A kind of inorganic fireproof insulation material and its manufacturing process

Abstract

The present invention is an inorganic fireproof and thermal insulation material, which is composed of water glass glue (solid content 40% to 85%), calcium carbonate, aluminum oxide, zinc oxide, magnesium oxide, burnt gemstone fine powder, titanium dioxide, and ferric oxide , red mud, chopped glass fiber (or nylon fiber) plus foaming agent, waterproofing agent. The raw materials can be obtained by mixing and stirring, forming, foaming and drying at a high temperature of 180°C to 350°C, and demoulding. Light weight, good heat preservation effect; the combustion performance meets the national A-level standard for fireproof materials. A certain amount of toughness. The production process does not require coal combustion, and there is no "three wastes" discharge. It is a clean production, energy-saving and water-saving. It is non-toxic, tasteless, and has no harmful radiation. It is a "green fireproof and thermal insulation material".

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a process for making fireproof and thermal insulation materials by using inorganic substances. Background technique [0002] At present, the common insulation materials in the insulation material market at home and abroad are as follows: 1) Organic insulation materials: EPS polystyrene foam materials, XPS extruded ethylene foam materials, polyurethane foam materials, etc.; 2) Inorganic insulation materials: rock wool , slag wool, glass wool, aluminum silicate, cement (or fly ash, magnesium oxide) foaming materials, etc.; 3) organic and inorganic mixed insulation materials: cement (or fly ash) polystyrene granular concrete insulation materials, etc. . The above heat insulating material has the following problems. 1) Although organic insulation materials have good insulation effect and light weight, they are easy to burn. With the country's emphasis on fire protecti...

Problems solved by technology

2) Although rock wool, mineral wool, and glass wool meet the requirements of Class A standards for fire resistance, the production process consumes energy and pollutes the environment. The materials themselves have certain damage to human skin, and at the same time, the cost of materials is also high

Cement (or fly ash) foaming material, the fire performance meets the requirements of Class A, but the volume is large, more than 450 kg per cubic meter, the insulation effect is not good, and it is only used for wall filling; the fire performance of aluminum silicate material is also Class A, the insulation effect is also very good, but the cost is high, the price is expensive, and the marketing is greatly affected

3) Cement (or fly ash) polyphenylene particle concrete material, although it meets the requirements of fire prevention and heat preservation, it has a large capacity and its application range is also subject to great limitations
