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...
