Novel high-strength low-volume-weight heat preservation fireproof decoration integration plate and preparation method thereof

Abstract

The invention relates to a novel high-strength low-volume-weight heat preservation fireproof decoration integration plate. The technical scheme includes that the integration plate is composed of a heat preservation layer, a fireproof layer which is coated on the outer surface of the heat preservation layer, a strengthening layer and decorative surface layer. The heat preservation layer is composed of polyurethane foaming plate double-faced composite cement alkali-resistant glass fabric. According to the plate and the preparation method, the strength is high, the heat preservation performance is high, the volume weight of the integration plate is less than 8kg / m2, compared with the volume weight of a conventional integration plate, the volume weight of the integration plate is reduced by 4-6kgm2, fireproof interface agent processing is performed on six surfaces of a core material, compared with existing products, the plate improves the fireproof performance substantially, and fire is prevented from spreading along a wall body.

Description

technical field [0001] The invention belongs to the field of building boards, and in particular relates to a high-strength, low-density integrated board for heat preservation, fire prevention and decoration. Background technique [0002] With the advent of the 21st century, under the guidance of the scientific outlook on development, the construction field has made it clear that a new industrialization road that is resource-saving and environment-friendly must be taken. For building energy conservation, the most critical link is the promotion of the use of new high-efficiency energy-saving thermal insulation materials and the reduction of energy consumption during construction. The emerging thermal insulation and decoration integrated board has become the focus of the construction industry. [0003] This thermal insulation and decoration integrated board is made by combining the front and back sides of insulation materials such as extruded board, benzene board, polyurethane...

AI Technical Summary

Problems solved by technology

[0004] However, the current thermal insulation and decoration integrated board has the following disadvantages: First, the fire performance is poor, and there is no fire protection layer around the integrated board, which cannot prevent the fire from spreading horizontally

This is inconsistent with the emphasis on energy saving of thermal insulation materials, and it is difficult to fully promote it as a high-efficiency energy-saving thermal insulation material

The rock wool insulation material, which has the advantages of fire prevention and heat preservation, has always been difficult to be widely used because of its high price and short period of rock wool sinking, resulting in a void in the upper part and fatal hazards to the lungs of construction workers.

With the application of thermal insulation and decorative integrated panels more and more widely, the original design ideas and product structure have obviously failed to meet the needs of the current building thermal insulation industry
