Embodiment 1

[0018] Such as figure 1 As shown: the present invention is a decorative and thermal insulation composite board, which includes a decorative coating 1, a surface layer 2, and a thermal insulation layer 4; between the thermal insulation layer 4 and the surface layer 2, a solvent resistant, adhesive Polyurethane rigid foam plastic layer 3 with high capacity, the polyurethane rigid foam plastic layer 3 bonds the surface layer 2 and the insulation layer 4 together, so that they and the decorative coating 1 form a composite board with a four-layer structure. In this embodiment, the insulation layer 4 is an extruded polystyrene foam board; the surface layer 2 is a glass fiber reinforced magnesium oxychloride cement board; the decorative coating 1 is a metal fluorocarbon paint, and the polyurethane rigid foam plastic layer 3 is a polyurethane rigid foam Plastic, bulk density is 60kg / m 3 , the bulk density can be 20~100kg / m 3 Between them, the thermal conductivity is 0.024W / mK, and t...

Embodiment 2

[0020] When making the composite board, the polyurethane rigid foam plastic layer 3 is wrapped around the four sides of the thermal insulation layer 4, which ensures that the thermal insulation layer 4 will not be dissolved when the decorative coating 1 is applied, and the other structures of the composite board are the same as in Example 1. .

[0021] The production method of the composite board of the present invention is as follows: After cleaning the back of the surface layer board, place it in the forming mold of polyurethane hard foam plastic with the insulation layer board, heat the mold, make the surface layer board and the insulation layer board preheat, preheat The temperature is between 20 and 50°C, and then cast polyurethane rigid foam plastic and heat it through the mold. The polyurethane rigid foam plastic material begins to react and expand, releases reaction heat and forms expansion pressure, and the liquid material fills the mold space and wraps it under the ac...

Abstract

A method for preparing composite board of decoration and insulation includes placing surface layer board and insulation layer board in forming mould of polyurethane hard foaming-plastic material, pouring said material and heating mould to expand said material and to let said material wrap insulation layer board, curing them in mould after said material is solidified, taking them out from mould and coating decoration layer to obtain composite board product with four layers.

Description

1. Technical field: [0001] The invention relates to a thermal insulation composite board and a production method thereof, in particular to a thermal insulation composite board used in a decorative thermal insulation system of building exterior walls and a production method thereof. 2. Background technology: [0002] In the decorative insulation system of building exterior walls, polystyrene boards, extruded polystyrene boards, etc. are usually used as thermal insulation materials, and paints, facing bricks, metal fluorocarbon paints, etc. are usually used as decorative materials. Among them, quality problems often occur in the engineering application of building exterior wall decoration and thermal insulation systems using metal fluorocarbon paint as decorative materials. The main reasons for the analysis are as follows: [0003] The method is to use polymer mortar to paste polystyrene board and extruded polystyrene board on the base of the building's outer wall, then hang ...
