Abstract

PURPOSE:To obtain a porous floor material hard to be slid and improve durability by connecting two kinds or more of bulk materials having different affinities with thermo-setting resin in the liquid state at the ordinary temperature with this thermo-setting resin and molding the mixture into the porous floor material. CONSTITUTION:Thermo-setting resin 4 in the liquid state at the ordinary temperature and two kinds or more of bulk materials 2 and 3 having different affinities with the thermo-setting resin 4 are connected. In this case, the thermo-setting resin 4 and the bulk material 3 having a lower affinity with it are mixed in advance, then the bulk material 2 having a higher affinity is mixed. The mixture is molded to manufacture a porous floor material 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a porous floor material that has excellent water permeability and is particularly resistant to slipping even when used in wet conditions.

[Conventional technology]

Flooring materials used in places that frequently get wet, such as bathrooms, kitchens, toilets, and entrances, are required to be particularly resistant to slipping when wet.

Conventionally, the following techniques have been known regarding this type of floor material.

By connecting and solidifying the surface of aggregate such as sand with a particle size of 0.00.31 or more with a thermosetting resin, a water permeable resin concrete layer with continuous water permeable pores formed between the aggregates is formed, and this water permeable pore This allows water to permeate from the surface of the floor material to the back side, thereby preventing slipping when wet (for example, see Japanese Utility Model Publication No. 15308/1983).
.

■ By scattering particles on the surface of a floor material made of vinyl chloride resin, it imparts anti-slip properties to the surface of the floor material (for example, U.S. Pat. No. 4,196,243 and U.S. Pat. No. 4,239). , No. 797 Specification Reference 11q).

■While forming unevenness on the surface of the flooring material, the surface is
I<L, and by providing an elastic body on the surface, anti-slip properties are imparted to the surface of the flooring material (for example, U.S. Pat. No. 4,
336,293 and U.S. Pat. No. 4,403,0
(See specification No. 09).

[Problem to be solved by the invention]

However, in the configuration (2) above, since the diameter of the water permeable hole is large, foreign matter enters the water permeable hole along with water, causing clogging and reducing water permeability. In the configurations of ■ and ■ above, slipping is prevented by providing roughness to the surface of the floor material, such as by providing unevenness on the surface.
There are problems in that it gets dirty easily and has poor surface smoothness.

In addition, if only powders with a high affinity are used, the pore diameter needs to be increased in order for water to flow into the pores formed between the powders. If so, the floor material is likely to be non-durable.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide a flooring material that is resistant to clogging and resistant to slipping even under conditions of use where it is frequently wet. Another object of the present invention is to provide a flooring material with excellent surface smoothness.

[Means for Solving the Problems] The porous floor material of the present invention has a thermosetting resin that is in a liquid state at room temperature, and at least two types of powder particles having different affinities with the thermosetting resin. Combined and molded.

The method for producing a porous floor material of the present invention involves bonding at least two or more types of powder or granules that have different affinities with the thermosetting resin using a thermosetting resin that is in a liquid state at room temperature. Powder with low affinity is mixed in advance, and then powder with high affinity is mixed and molded.

The thermosetting resin that is in a liquid state at room temperature and used in the present invention includes unsaturated polyester resins, epoxy resins, polyurethane resins, etc. that can be used in a liquid state at room temperature.

In addition, granules include fillers such as heavy calcium carbonate and whitebait powder used in resin concrete, and JIS A 5
Structural lightweight concrete aggregate as specified in 002;
Also used are fiber reinforcing materials such as nylon fibers, vinylon fibers, glass fibers, and carbon fibers used in composite materials.

The powders and granules that have different affinities with the resin used in the present invention include those that are the same type of powder that has been surface-treated to have different affinities, or those that have a maximum resin content per unit filling volume. There are products that are divided into different powders and granules.

The blending ratio of the thermosetting resin and the powder is 200 to 1200 parts by weight per 100 weight parts of the resin.

[Function] As mentioned above, when two or more types of powder particles having different affinities with the thermosetting resin are bonded together using a thermosetting resin that is in a liquid state at room temperature, the amount of resin is kept to a small amount, the floor is formed. - The material is porous and has anti-slip properties even though the surface is smooth. By reducing the blending ratio of powder to thermosetting resin, a floor material with denser porosity can be obtained.
