Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to window materials made of transparent plate-like bodies, particularly glass plates, synthetic resin plates, etc., such as flat plate-shaped, bent plate-shaped raw or reinforced Single-panel, laminated, laminated, multi-layer, architectural window materials with film or other processing applied to the surface of the panels, vehicle window materials, etc., especially synthetic resin moldings or gaskets directly on the outer surface of the peripheral edges of automotive window materials. (Hereinafter, both are also referred to as malls)
This invention relates to a window material formed by integrally molding the above and its manufacturing method.

[Conventional technology]

Conventionally, as a means of attaching a transparent plate-like body such as a glass plate to a vehicle window opening, in the case of an automobile, it has been fitted to the joint between the inner panel and the outer panel of the vehicle body, and to the peripheral edge of the glass plate. The glass plate is attached to the car body through a separately molded weather strip, and the legs are inserted between the glass plate and the periphery of the glass plate mounting flange on the car body panel and fixed with adhesive. The so-called direct glazing method, which uses a separately molded peripheral molding, has been adopted, and a mounting method that has recently been gaining attention is to directly integrally mold a molding or gasket on the outer surface of the peripheral edge of the glass plate in advance by reaction injection molding, etc. The so-called encapsulation method is being adopted, in which the capacitor is easily attached to the vehicle body with one touch using adhesive or the like.

Among them, for example, Japanese Patent Application Laid-Open No. 61-66645 describes a window material assembly and its manufacturing method, which includes a main body made of a transparent plate material and a transparent material overlaid and attached to at least one side of the main body. Tear-resistant window assemblies are disclosed having a layer of synthetic resin material and a gasket formed in-situ and bonded to the periphery of both parts, and methods of making the same.

In addition, Japanese Utility Model Application Publication No. 158508/1988 describes a windshield glass detachment structure, which includes a holding means that detaches the glass from the vehicle body when an impact of more than a predetermined value is applied to the windshield glass, and a gap between the glass and the vehicle body. Absorbing means attached directly to or via a holding means and absorbing energy received by the glass when the glass moves,
There are known devices that attempt to reduce the impact load placed on the windshield glass by an occupant during a vehicle emergency.

[Problem that the invention seeks to solve]

As mentioned above, the conventional method described in JP-A No. 61-66645 is intended to prevent tearing by providing a layer of transparent synthetic resin material on a transparent plate material, and is not suitable for window materials. A polymer frame member is formed on-site to surround the peripheral edge of the transparent plate and the synthetic resin material layer to ensure sufficient adhesion at the peripheral edge,
Rather, it is intended to sufficiently adhere the transparent plate material and the synthetic resin material layer, and it does not necessarily make sufficient use of the polymer frame member itself that surrounds the peripheral edge of the window material to absorb impact energy in the event of a collision. It is not something that was originally intended. Also, Utsukai Showa 61-
The structure described in Publication No. 158508 has a complicated shape and a large number of members provided at the end of the windshield glass, a complicated configuration of the holding and absorbing means, and requires a high stacking capacity. The installation work was also inefficient, and the instrument panel of the vehicle body also required a certain shape.

[Means for solving problems]

The present invention has been made in view of the above-mentioned drawbacks of the conventional art.The present invention has been made in view of the above drawbacks of the conventional art. The present invention provides a window material and a manufacturing method thereof that can solve the above-mentioned problems by integrally molding a molding or a gasket on the peripheral edge of a transparent plate-like body.

That is, the present invention provides a window material in which a synthetic resin molding or gasket is integrally molded on the outer surface of the peripheral edge of a transparent plate, and at least one through hole is provided at a predetermined location on the peripheral edge of the transparent plate. A spring mechanism member passing through the through hole connects the decorative/reinforcing member on the outer surface of the molding or gasket with the base material facing the back surface, and the spring mechanism member is provided with a spring mechanism member passing through the through hole. A window material characterized by being integrally molded so as to be built-in, and a method of integrally molding a synthetic resin molding or gasket on the outer surface of the peripheral edge of a transparent plate-like body,
A predetermined portion of the peripheral edge of the transparent plate-like body is placed in a mold, at least one through hole is bored at a required location in the peripheral edge of the transparent plate-like body, and a spring passes through the through hole. Decorative/reinforcing members are placed on the inner surface of the mold via a mechanical member, positioned in pressure contact, and pressed and fixed by mold clamping, and at the same time, the transparent plate-like body is held by the clamping portions of the mold member using a sealing material. A window material characterized in that the synthetic resin is integrally molded into a cavity space constituted by the inner surface of the mold, the outer surface of the peripheral edge of the transparent plate-shaped body, and the inner surface of the decorative/reinforcing member, and then taken out from the mold. It provides a manufacturing method.

Here, the term "transparent" in the transparent plate-like material refers to transparent, translucent, colored, uneven surface patterns, etc.; Various types of glass such as
Namely, flat glass, tempered plate glass by heat treatment or chemical treatment, various types of laminated glass made by combining glass plates, resin plates, etc., laminated glass with various surface treatments such as heat ray reflective coating, tear prevention coating, black frame, etc., bent plate glass, These include various inorganic glasses such as double-layer glass, hard-coated synthetic resin plates such as polycarbonate, acrylic, and scratch-resistant sheets, and laminates made of these synthetic resin plates and inorganic glass plates.

The through-holes to be bored in the peripheral edge of the transparent plate-like body should have a diameter that does not come into contact with the spring mechanism member, a shape similar to that of a through-hole, and a number of through-holes at required locations around the entire circumference. At least one type or more is required, and although it is better to provide the same cross section as the locking rib portion in terms of strength, it may be provided in other locations.

The molding that is integrally molded onto the transparent plate-like body is applied to the peripheral edge of the transparent plate-like body over the entire circumference or almost the entire circumference, and various shapes are adopted for the molding, but at least transparent It is integrally molded on one of the front and back sides and the end face of the peripheral edge of the plate, and it goes without saying that it is preferable to apply a primer to the required areas in advance to improve adhesive strength. It is preferable to have a shape that satisfies a more aerodynamic structure and does not cause unpleasant wind noise, and is provided with a tongue portion to improve sealing performance with the outer skin of the vehicle body. It is preferable that the back surface of the transparent plate has an uneven shape or a shape that has some kind of spring effect, and furthermore, a protruding piece (for sealing) is provided around the entire circumference of the transparent plate on the rising surface corresponding to the end face side of the transparent plate. Or, it is preferable to make it airtight by incorporating a flexible hollow tube in its surface, and furthermore, it can be fixed by adhesive or by engagement when it is installed in alignment with an opening in a vehicle body, etc. Therefore, the back side of the molding has an uneven or concave shape to prevent the bead-shaped adhesive applied to this area from leaking, and a dam part is provided at the end for the purpose of sealing. It is preferable to provide at least one locking rib portion for positioning the material at the vehicle body opening, fixing it until the adhesive is fixed, and assisting with subsequent fixing.

The molding can be molded using general synthetic resin molding methods such as injection molding, and in particular RIM (Reaction Injection) method.
Molding), R-RIM method (particularly those with reinforcing materials), LIM method (Liquid Injection)
Molding), R-LIM method (particularly those containing reinforcing materials), among which RIM
Preferably, it is based on the law. In other words, while it generally requires a temperature of about 200 to 300℃ for the part of the mold surrounding the cavity space,
The temperature can be as low as 100°C to normal temperature, preferably as low as 50 to 80°C.
It is preferable to be able to adjust the temperature of not only the mold holding temperature but also the non-molded part because it allows the solidification rate etc. to be controlled.
Materials that require an extremely high pressure of 350 to 1000 Kg/cm ² are injected into the cavity space at a pressure ranging from normal pressure to about 6 Kg/cm ² , preferably around 3 Kg/cm ² , and are injected into the cavity space at an extremely low pressure. It has the advantage that, for example, two components are mixed by collision and then reacted and injected. The mold itself is not particularly limited, and may be made of extremely common metal, resin, or ceramic, and the surface of the cavity space may be treated with a mold release agent, or a transparent plate-like material may be used. A substance that doubles as a sealing member and a buffering member different from the injected resin, so as not to damage or break the surface of the body, and also to prevent the generation of burrs and absorb deformation of molds and transparent plate-like bodies. For example, an elastic body such as a heat-resistant fluororesin or fluorine rubber, silicone resin or silicone rubber, or other soft resin, such as a single body, a foam, a hollow body, or a composite body, is interposed between the transparent plate-like body and the mold surface. Needless to say, it must be sealed tightly.

The decorative/reinforcing members set in the mold can be metal or resin films or plates of various sizes, thicknesses, and shapes, and are set by a spring mechanism.
In conjunction with mold clamping, it can be firmly clamped and fixed in the mold regardless of the transparent plate-like object, and it can also absorb mold distortion and transparent plate-like object distortion, which may cause positional distortion during injection injection of synthetic resin. It is possible to accurately position the synthetic resin so as not to cause any damage, and after the synthetic resin has solidified from a liquid state, the spring force can be eliminated by the resin, making it sturdy.
Further, depending on the synthetic resin used, the strength of the spring force can be freely selected, and various materials and types of spring mechanism members can be selected, and springs are preferred.

The spring mechanism member is directly bonded to, for example, the outer panel of the vehicle body, and as a result, the decoration/reinforcement member is also a spring mechanism member that is attached directly to the outer panel of the vehicle body, regardless of the molding.

The synthetic resins used in the various molding methods, that is, the synthetic resins that can be used in the present invention, include, for example,
Polyurethane resin, low density and high density polyethylene, polystyrene, polypropylene, silicone resin, polyamide resin, nylon-6,
Thermoplastic resins such as EVA, PET, and PBT, thermoplastic rubbers such as polyurethane, ethylene-vinyl acetate, polyolefin, and styrene-butadiene, as well as vinyl ester resins, epoxy resins, silicone resins, and unsaturated polyesters. These include thermosetting resins such as thermosetting resins, blended resins, foamed polyurethane, elastomers, elastic rubbers, etc., which can be widely used, as well as ultraviolet absorbers, colorants, catalysts that control the reaction rate, It goes without saying that fillers such as foaming agents and stabilizers, as well as reinforcing agents such as glass fibers and glass flakes, may be added. Of course, it is necessary to consider weather resistance, heat resistance, strength, coefficient of thermal expansion, shrinkage ratio, surface texture, etc.

[Effect]

As mentioned above, the window material and the manufacturing method of the present invention allow various decorative and reinforcing members to be integrally molded by various combinations of the spring force and holding force of the spring mechanism and the physical properties of the metal or synthetic resin molding itself. At the same time, the decorative and reinforcing members that become the outer surface can be attached and held directly to the mounting frame, such as the outer panel of the vehicle body, using spring mechanism members, reducing the impact load on the occupant's side shield glass even in the event of a vehicle collision, for example. It provides more functional effects, such as relaxation and increased penetration resistance.

In other words, due to the spring force of the spring mechanism,
Decorative and reinforcing members can be reliably positioned within the formwork,
The transparent plate-like body can be held in pressure contact with the inner surfaces of the cavity mold and core mold without any load, and can be further pressed during mold clamping and absorb mold deformation, and is also useful when injecting liquid synthetic resin. This also makes it possible to prevent burrs from forming on the outer surface of the decorative/reinforcing member without causing any misalignment or the like. Also, depending on the holding force of the spring mechanism, the size of the decorative/reinforcing member,
It can be integrally molded with a variety of thicknesses and shapes, resulting in high finishing accuracy and eliminating variations in positioning accuracy between each component.For example, it is now possible to attach and paste these components, which was previously done after installation on the outer panel of the vehicle body with an opening. This eliminates the need for additional work, allows for a more aesthetically pleasing finish, and makes full use of the physical properties of the integrally molded synthetic resin molding.
For example, a transparent plate-like body can be made to hold more flexibly and absorb the impact energy of an object, allowing for a wide range of highly functional moldings to be selected. This makes it possible to flexibly respond to variations in surface inclination accuracy and distortion between the window material and the frame of the vehicle body exterior panel, etc., during installation, and to greatly improve the sealing performance, adhesion, and fixing performance between them. This improves the maintenance of watertightness and airtightness, and as a result, increases the holding power and durability of the transparent plate, and the installation work can be easily automated using machines without creating stress. Automation is possible, and the transparent plate-like body is not damaged or damaged during installation.
