Pearlite fiber composite fire-proof heat insulation board

Abstract

The invention relates to a fire-proof material, in particular to a fire-proof heat insulation material used for filling an interlayer of fire protection equipment such as fireproof door and the like, and fire-proof heat insulation decorating material used for a fire-resistive partition in building and decorating. The invention aims at providing the fire-proof heat insulation material which has the advantages of higher compression strength and impact-resistant strength, wide application scope and longer service life, and the novel fire-proof heat insulation material also has higher fire-proof heat insulation property, does not pollute the environment and harm the human health and is lighter in specific gravity. The invention makes up the defects that the existing expanded perlite heat insulation board is fragile when being collided and short in the service life. In order to achieve the aim, the invention adopts the scheme that the novel fire-proof heat insulation material comprises the components based on parts by weight: 40-90 parts of expanded perlite powder particles, 10-50 parts of bonding agent and 5-60 parts of glass fiber.

Description

Technical field: [0001] The invention relates to a fireproof material, in particular to a fireproof and heat-insulating material used for filling interlayers of fireproof equipment such as fire doors, and a fireproof and heat-insulating decorative material used for fireproof partitions in construction and decoration. Background technique [0002] At present, most of the materials used for fire prevention and heat insulation are aluminum silicate wool, asbestos, volcanic rock ash, coal ash, vermiculite or perlite. Aluminum silicate wool or asbestos is particularly harmful to the human body due to needle-like dust overflow. It is a carcinogen, and its use is gradually restricted or eliminated. It has been banned in the United States, and asbestos (rock wool) has been gradually banned in China; volcanic rock ash and coal ash are not uniform due to uneven powder particles, large bulk density, and insufficient heat resistance.

Problems solved by technology

[0002] At present, most of the materials used for fire prevention and heat insulation are aluminum silicate wool, asbestos, volcanic rock ash, coal ash, vermiculite or perlite. Aluminum silicate wool or asbestos is particularly harmful to the human body due to needle-like dust overflow. It is a carcinogen, and its use is gradually restricted or eliminated. It has been banned in the United States, and asbestos (rock wool) has been gradually banned in China; volcanic rock ash and coal ash are not uniform due to uneven powder particles, large bulk density, and insufficient heat resistance. It is not the first choice for light fireproof materials with high requirements. Expanded perlite products are being popularized and used because they are light in weight, harmless to human body and environment, and have high heat insulation and fire resistance performance. The manufacturing process of expanded perlite products is relatively different. Large, the main process is to mix expanded perlite with adhesive, compression molding, and drying, which is an ordinary perlite fireproof board, but this kind of perlite fireproof board is not strong enough and easy to break, and people have also taken some measures. For example: Patent Publication No. CN101279826A "Perlite insulation board for fire door filling and its preparation method"; it is better to bond flame-retardant cloth, kraft paper or interlayer fiber net in the middle of perlite products on the surface and bottom of the product, etc. For example, as represented by the patent 200820008255.2 "Strength Improvement Structure of Perlite Fireproof Material", due to the limitation of the production material and its performance, it is difficult to obtain high compressive strength and impact strength for the perlite products, and it is easy to be damaged by collision and impact. The rock powder of perlite products is scattered or damaged, which seriously affects the performance, service life and scope of use of perlite fireproof and heat insulation products
