Problems solved by technology

Although these insulation boards are all Class A fireproof boards, each material has certain disadvantages, among which: the material itself and production cost of the foamed ceramic insulation board are high, which is difficult to accept in the market; the strength of the composite cement foam insulation board is low Easy to shrink and crack; the material of aerated concrete slabs has poor thermal insulation; rock wool board composite board, that is, a layer of cement and other fabrics are compounded on both sides of the rock wool board to increase its strength. Although this kind of board has better flame retardant and thermal insulation effects , due to the increase of the surface layer, its bulk density is heavy and its strength is low; although the vitrified microbead board is light in weight and good in heat preservation, its product strength is low and its water absorption rate is high
[0003] Chinese patent, the application number is 02138944.6, the application date is 2002-08-15, and the publication number is: 1415568.

Abstract

The invention provides an environment-friendly fireproof insulation plate and a production process thereof. The environment-friendly fireproof insulation plate is a block-shaped plate manufactured by 45-80% of vitrified micro ball, 15-35% of rock cotton fiber and 5-20% of water glass in percentage by weight according to the sequence of mixing, spreading, continuously flatly pressing, curing on line and cutting on line. The environment-friendly plate made from an inorganic material has the advantages of environmental friendliness, light weight, high strength, low heat conducting coefficient and good insulation performance, the volume weight is lower than 200 kg / cube, the fire protection level is high (level A), and the indexes of the state level-A plate are satisfied. At the same time, the processes of continuously flatly pressing and curing on line are adopted, so that the defect of lower production efficiency in the traditional insulation plate production process using mould pressing or plate frame forming or the like is overcome, the production cost is lowered, and the production efficiency is improved.
