Detailed ways

The present application will be described in further detail below in conjunction with accompanying drawings 1-7.

The embodiment of the application discloses a foam insulation board.

Example 1

Referring to Fig. 1, a foam insulation board includes an insulation layer 1, which is bonded to the building wall during construction, and the side of the insulation layer 1 away from the building wall is the grouting surface 11. Smear mortar on the grouting surface 11 of the insulation layer 1, and form a certain thickness of the mortar layer 2 after the mortar solidifies, and the mortar layer 2 is used to increase the strength of the insulation layer 1.

The insulation layer 1 is composed of spherical polyphenylene particles with different diameters, and the diameter range of the particles is 2.0-2.5mm. Due to the material properties of polyphenylene particles, a single polyphenylene particle will shrink after being heated.

Before the mortar is applied, the application surface 11 of the thermal insulation layer 1 is heated, and the application surface 11 will form a plurality of uniform grooves 3 due to heat shrinkage of the polystyrene particles, and the indentation depth is 0.5-1.2 mm. Smear mortar on the smearing surface 11 that has groove 3 again, and groove 3 increases the surface area of smearing surface 11, has slowed down the speed that mortar flows downward due to its own weight, thereby strengthened the grouting ability of insulating layer 1, makes mortar Layer 2 is not easy to fall off.

Referring to Fig. 4, a plurality of chute 31 intersecting each other is opened on the grouting surface of the thermal insulation layer 1, and a plurality of chute 31 intersect each other on the grouting surface to form a rhombus grid shape, thus, a plurality of slanting grooves 31 intersecting each other The groove 31 prolongs the flow path of the mortar, and further slows down the downward flow of the mortar under the action of friction, so that the grouting on the grouting surface 11 is more uniform.

Referring to Fig. 2, in order to enhance the protective effect of the mortar layer 2 on the insulation layer 1, a layer of glass fiber mesh 21 can be pre-embedded before the mortar is applied, and the glass fiber mesh 21 is used as the skeleton of the mortar layer 2, which improves the resistance of the mortar layer 2. Tensile strength, so that the mortar layer 2 is not easy to crack.

Referring to FIG. 2 , in order to make the connection between the grouting surface 11 and the mortar layer 2 more firm, several connecting pieces 4 can also be arranged between the grouting surface 11 and the glass fiber mesh 21 . The connector 4 includes two parts: a patch 41 and a connecting rod 42. The connecting rod 42 is perpendicular to the patch 41. The patch 41 and the connecting rod 42 can be connected by welding or integral molding.

Utilizing the characteristics of the groove 3 to increase the surface area of the grouting surface 11, it is preferable to fix the patch 41 on the insulation layer 1 by gluing, and the end of the connecting rod 42 away from the patch 41 passes through the glass fiber mesh 21 and bends upwards At this time, the glass fiber mesh 21 is hung on the connecting rod 42, and then the mortar is applied.

The bent connecting rod 42 restricts the movement of the glass fiber mesh 21 from the horizontal direction and the vertical direction at the same time, so that the mortar layer 2 and the insulation layer 1 have a more reliable connection method besides bonding, which improves the foam insulation performance. board quality.

The implementation principle of a foam insulation board in the embodiment of the present application is:

During the production of foam insulation boards, since the unsolidified mortar will flow downward along the grouting surface 11, the thermal insulation layer 1 will be heated to shrink the polystyrene particles, and then a plurality of uniformly distributed concave holes will be formed on the grouting surface 11. Groove 3, to increase the surface area of the grouting surface 11 in contact with the mortar, slow down the speed of the mortar flowing downward due to its own weight, thereby improving the grouting ability of the insulation layer 1, making the grout not easy to slip, and improving the mortar layer 2 The problem of poor quality insulation boards caused by unevenness.

However, the connection between the grouting surface 11 and the mortar layer 2 relies on vertical friction, so a connecting piece 4 is set between the grouting surface 11 and the glass fiber mesh 21, and the connecting piece 4 limits the horizontal direction. The movement of the glass fiber mesh 21 improves the connection strength between the insulation layer 1 and the mortar layer 2 .

Example 2

The difference between embodiment 2 and embodiment 1 is that: instead of setting up rhombus grid-like chute 31 on the grouting surface 11 of the insulation layer 1 , the slotting method is changed to wave-shaped groove 32 .

Referring to Fig. 7, a plurality of wavy grooves 32 arranged at intervals are provided on the grouting surface 11, and the length direction of the wavy grooves 32 is along the horizontal direction, which can also prolong the mortar flow path and slow down the mortar flow speed.

All of the above are preferred embodiments of the application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made according to the structure, shape, and principle of the application should be covered by the protection scope of the application. Inside.
