Compound insulation board

Abstract

The invention relates to a compound insulation board, comprising two layers of cement fibreboards and a middle layer arranged between the two layers of cement fibreboards. The compound insulation board is manufactured by mixing and stirring the following components by weight percent: 7.5-8.5% of cement, 5-7% of yellow sand, 2.5-3.5% of coal ash, 80-83% of polystyrene particle and 1.5-2.5% of resin powder. Compared with the existing compound insulation board, the compound insulation board of the invention has better thermal insulation effect and has high strength and excellent fireproof and waterproof properties.

Description

technical field [0001] The invention relates to a composite thermal insulation board. Background technique [0002] At present, most of the wall materials in my country are made of solid clay bricks. Due to the high energy consumption of solid clay bricks and their poor thermal insulation effect, the annual energy consumption of wall materials and building heating is nearly 150 million tons of standard coal. Therefore, it is an urgent matter to develop new wall materials with energy saving, environmental protection, heat preservation and heat insulation. [0003] Traditional thermal insulation materials for buildings include cement vermiculite, cement perlite, overhead insulation boards and aerated concrete blocks. Although these thermal insulation materials can play a certain role in thermal insulation, they are expensive , Moisture-proof and poor waterproof performance, especially the aerated concrete block also has the problem of wasting land resources and energy.

Problems solved by technology

[0002] At present, most of the wall materials in my country are made of solid clay bricks. Due to the high energy consumption of solid clay bricks and their poor thermal insulation effect, the annual energy consumption of wall materials and building heating is nearly 150 million tons of standard coal. Therefore, it is an urgent matter to develop new wall materials with energy saving, environmental protection, heat preservation and heat insulation.

[0003] Traditional thermal insulation materials for buildings include cement vermiculite, cement perlite, overhead insulation boards and aerated concrete blocks. Although these thermal insulation materials can play a certain role in thermal insulation, they are expensive , moisture-proof, and poor waterproof performance, especially the aerated concrete blocks still have the problem of wasting land resources and energy

At present, it has become a trend to use waste foam plastics and cement as raw materials to make thermal insulation wallboards. Brick, its thermal insulation performance and waterproof and fireproof performance cannot meet the requirements of construction engineering for the performance of thermal insulation materials
