Abstract

The invention provides a heat insulation plate with heat insulation and heat radiation effects, and relates to the technical field of heat insulation building materials. The heat insulation plate comprises a pasting layer, a fire-retardant agent layer, a heat insulation layer, a protection layer, a finish layer and heat radiation holes, wherein the fire-retardant agent layer is arranged under the pasting layer 1, the heat insulation layer is arranged under the fire-retardant agent layer, the protection layer is arranged under the heat insulation layer, the finish layer is arranged outside the protection layer, and the heat radiation holes are respectively formed in the pasting layer, the fire-retardant agent layer, the heat insulation layer, the protection layer and the finish layer. The heat insulation plate has the following beneficial effects that economical and practical effects are achieved, the performance is stable, the aging deformation cannot occur, any pollution cannot be caused on environment, the sintering is not needed, the heat insulation plate belongs to a novel wall body material integrating the environment protection, the energy saving, the fire-proof effect, the water-proof effect, the heat insulation and the decoration, meanwhile, the production and the installation are simple, the implementation is easy, and the mass popularization generalization can be realized.

Description

Technical field: [0001] The invention relates to the technical field of thermal insulation building materials, in particular to a thermal insulation board with thermal insulation and heat dissipation effects. Background technique: [0002] The insulation board is easy to understand, it is a board for building insulation. Insulation board is a rigid foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, mixed with heat and injected with catalyst, and then extruded and formed. It has moisture-proof and waterproof properties. It can reduce the thickness of the building's outer envelope, thereby increasing the indoor usable area. [0003] The common types on the market are as follows: [0004] Extruded plastic insulation board: it has a dense surface layer and an inner layer with a closed-cell structure. Its thermal conductivity is much lower than that of EPS with the same thickness, so it has better thermal insulatio...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages: The strength of the board itself is high, which makes the board more brittle and not easy to bend. The stress on the board is concentrated, which is easy to damage and crack the board; the air permeability is poor, almost impermeable, if the temperature difference between the two sides of the board is large , the humidity is high and it is easy to condense; due to the smooth surface of the board, interface treatment and roughening are required during construction

[0007] Disadvantages: The formula and ratio of insulation boards are messy and unstable, which leads to poor physical stability of the boards and poor insulation effect; the construction of spraying has not been solved, and it is difficult to guarantee the quality of the project

[0009] Disadvantages: The fire resistance grade is B grade, up to A2 grade, but it increases the cost

Organic matter cannot be resistant to aging, ultraviolet rays and other rays will act for a long time, and the phenolic insulation board will lose its function and shorten its life
