Problems solved by technology

However, the bonding of tiles and polyurethane is achieved through adhesives, because the thickness of the tile itself is about 10mm, and its weight is relatively heavy, about 20 kg per square meter, so it is easy to cause falling off
impact on future security

Embodiment 1

[0023] A polyurethane thermal insulation composite board is produced according to the following process: various conventional raw materials are prepared according to conventional ratios, the mold is closed, and then pouring and foaming are performed by a pouring machine. A high-density and high-hardness self-skinned polyurethane rigid foam board 1 is obtained, and its hardness is Shore 70D. Then apply polyurethane adhesive on its non-skinning side, and stick the low-density polyurethane rigid foam plastic plate 2 on its surface immediately. After the adhesive is cured, the polyurethane insulation composite board can be obtained.

Embodiment 2

[0025] A polyurethane thermal insulation composite board is produced according to the following process: various conventional raw materials are prepared according to conventional ratios, the mold is closed, and then pouring and foaming are performed by a pouring machine. A high-density and high-hardness self-skinned polyurethane rigid foam plastic plate is obtained, and its hardness is Shore 70D. Then use it as a bottom plate, put it into another mold, and perform foaming of conventional low-density polyurethane board on its non-skinning side to obtain a polyurethane thermal insulation composite board.

Embodiment 3

[0027] A polyurethane thermal insulation composite board, which is produced according to the following process: various conventional raw materials are prepared according to conventional ratios, and glass fiber or nano-calcium carbonate is added in an amount of 4-8% of the total weight of all the above-mentioned raw materials (minimum Preferably 6%) short glass fibers or nanometer calcium carbonate as reinforcing material, close the mold, and then use a pouring machine to pour and foam. A high-density and high-hardness self-skinned polyurethane rigid foam plastic plate is obtained, and its hardness is Shore 70D. Then use it as a bottom plate, put it into another mold, and perform foaming of conventional low-density polyurethane board on its non-skinning side to obtain a polyurethane thermal insulation composite board.

Abstract

The invention discloses a polyurethane heated composition board and a production method thereof, wherein, a heated board comprises a high-density high hard integral skin urethane foam plate on which a low-density urethane foam plate is compounded. The production method is as follows: the high-density high hard integral skin urethane foam plate is produced first, then the low-density urethane foam plate is compounded on the high-density high hard integral skin urethane foam plate through a cementing compound or direct foaming. The composition board is light in weight, safe and reliable, simple in process, can realize industrialized production and construction assembly manner.

Description

Technical field: [0001] The invention relates to a building material, which is a polyurethane thermal insulation board and a production process. Background technique: [0002] The previous polyurethane insulation technology usually adopts the method of spraying on-site construction, and utilizes the excellent bonding performance of polyurethane to bond to the surface of the wall to be insulated, so as to achieve the effect of energy saving and heat preservation. Polyurethane is a kind of bonding material with good bonding performance, which can bond well with the surface of many objects. But the insulating layer obtained by the method of such on-site construction, because there is no protection on the surface, it is easily damaged after being hit by hard objects, thereby losing the effect of insulating. And on-the-spot construction is difficult for vertical wall construction, is difficult to guarantee construction quality. Simultaneously, the surface of the insulating laye...
