Description
Technical field
The invention belongs to building materials field, particularly a kind of inorganics that utilizes is made fire-retardant heat-insulation material technology.
Background technology
The common lagging material in lagging material market has following several both at home and abroad at present: 1) organic class lagging material: EPS polystyrene foamed material, XPS extrusion molding ethylene foam material, polyurethane foamed material etc.; 2) mineral-type lagging material: rock wool, slag wool, glass wool, pure aluminium silicate, cement (or flyash, magnesium oxide) foam material etc.; 3) organism and inorganics mixing lagging material: cement (or flyash) granular polystyrene concrete thermal-insulating material etc.There is following problem in above-mentioned lagging material.1) though organic class lagging material high insulating effect is in light weight, easy firing.Along with the attention of country to fire safety problem, and the building field fire safety rules widely popularize enforcement, its use range is more and more littler.2) though rock wool, mineral wool, glass wool fire resistance reach the requirement of A grade standard, production process power consumption, contaminate environment, its material itself has certain injury to human skin, and simultaneously, material cost is also high.Cement (or flyash) foam material, fire resistance reaches the requirement of A level, but unit weight is big, and every cubic metre more than 450 kilograms, and heat insulation effect is not good enough, only limits to body of wall and fills and use; The aluminosilicate material fire resistance also is the A level, and heat insulation effect is also fine, but the cost height costs an arm and a leg, and marketing is subjected to very big influence.3) cement (or flyash) granular polystyrene concrete material, though reach fire prevention, insulation requirement, unit weight is big, use range is being greatly limited property equally.
