Embodiment 1

[0039] Apply the binder emulsion on the surface of the organic foam board 3 first, and let it dry naturally for 60-120 minutes; the formula of the binder emulsion is 1Kg of binder and 2.5Kg of water. The binder is an acrylate polymer.

[0040] Use a release agent to coat the inner surface of the insulation board mold; the release agent can be sodium silicate precipitation or sodium phosphate, and the most commonly used is waste engine oil.

[0041] Make wear-resistant cement slurry according to the following formula:

[0042] Toner 8Kg, white cement 300Kg, binder emulsion 15Kg, binder is acrylic ester polymer, defoamer 2Kg, defoamer is tributyl phosphate.

[0043] Pour the toner and white cement of the above components into a mixer and stir evenly, then pour in the binder emulsion and defoamer for stirring to form a cement slurry. Pour the prepared wear-resistant cement slurry into a mold suitable for the external dimensions of the insulation board to make the cement wear-re...

Embodiment 2

[0049] Make wear-resistant cement slurry according to the following formula:

[0050] Color powder 20Kg, white cement 400Kg, binder emulsion 30Kg, defoamer 5Kg.

[0051] Make the mixture as follows:

[0052] 650Kg of cement, 300Kg of quartz sand, 80Kg of lightweight hollow powder, 30Kg of binder, 8Kg of foaming agent, and 200Kg of water.

[0053] Others are with embodiment 1.

Abstract

The heat insulating board includes antiwear cement layer, organic foam layer and outside reinforcing layer comprising hollow powder, sand, cement and adhesive mixed together. The production process of the heat insulating board includes the following steps: smearing emulsion adhesive to the surface of organic foam board and painting demolding agent to the inside of the mold; pouring cement slurry into the mold to form the antiwear cement layer; pouring the mixture of light hollow powder, sand, cement, foaming agent and adhesive into the mold to form the reinforcing layer; setting foamed polystyrene board, covering one mixture layer, drying and demolding. The heat insulating board has multifunction, excellent heat insulating effect, light weight, high compression strength, low cost and other advantages.

Description

technical field [0001] The invention relates to building materials, in particular to a thermal insulation board for roofs or walls and a manufacturing method thereof. Background technique [0002] The traditional construction industry uses vermiculite as heat insulation material, but due to its troublesome construction and unsatisfactory heat insulation effect, it is gradually eliminated in the new building code. The use of polystyrene foam boards as building insulation materials has become the mainstream. This material has excellent thermal insulation performance, light weight and low price; its disadvantage is that it is easy to break and shrink, and it must be covered with a surface layer. However, due to its easy damage, it causes greater difficulty in the construction of the surface layer. Usually only one deck of barbed wire can be added so as to facilitate construction, which causes cost increase again. For example, the Chinese patent whose notification number is 22...
