Problems solved by technology

In this way, the bonding of tiles and polyurethane is achieved through adhesives. Although the weather resistance of the polyurethane insulation board is solved, the thickness of the tile itself is about 10mm, and its weight is relatively heavy, about 20 kg per square meter. Therefore, it is easy to cause falling off
impact on future security
At the same time, the production and construction are complicated

Embodiment 1

[0015] A continuous production method of weather-resistant polyurethane thermal insulation composite board,

[0016] (1) The raw materials for producing high-density self-skinned polyurethane foam are configured, the mold is closed, and foaming is poured with a pouring machine to obtain a high-density and high-hardness self-skinned polyurethane foam board; high-density and high-hardness polyurethane foam board The hardness is above Shore 60D.

[0017] (2) The high-density and high-hardness self-skinning polyurethane foam board is used as the bottom plate, and is input into a polyurethane horizontal foaming machine, and the low-density polyurethane board is foamed on the non-self-skinning side to obtain a polyurethane thermal insulation composite board. Finally, beautify and modify the surface of the self-crust to have a modified pattern.

Embodiment 2

[0019] When manufacturing the high-density and high-hardness self-skinned polyurethane foam plastic board, 4-8% of the total weight of the raw material of the high-density and high-hardness self-skinned polyurethane foam plastic board is added with glass fiber or nano-calcium carbonate. All the other are with embodiment 1.

Abstract

The invention discloses a method of continuously producing a weatherable polyurethane thermal-insulating composition board. The method comprises the steps of preparing the raw materials for producing the high-density self-mantling weatherable polyurethane foam; closing the mold, casting and frothing using a casting machine to obtain a high-density and high-rigidity weatherable self-mantling polyurethane foam panel; imputing the high-density and high rigidity weatherable self-mantling polyurethane foam panel as a base plate into a polyurethane horizontal frothing machine, and frothing the low-density polyurethane panel on the non-self-mantling side to obtain a weatherable polyurethane thermal-insulating composition board, which is light, safe, reliable, simple in process, and capable of realizing continuous industrial production, construction and assembly.

Description

Technical field: [0001] The invention relates to a production method of building materials, which is a polyurethane 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 i...
