Fireproof modified polystyrene foam heat preservation board and manufacturing method thereof

Abstract

The invention provides a fireproof modified polystyrene foam heat preservation board. The fireproof modified polystyrene foam heat preservation board is characterized by comprising a plurality of polystyrene foam boards integrally bonded with polystyrene particles and a fireproof material wrapping a polystyrene particle outer layer, the particle size of the polystyrene particles ranges from 4 mm to 5 mm, the weight ratio of the polystyrene particles to the fireproof material ranges from 1:5 to 1:6, the fireproof material is coated on the polystyrene particles of the fireproof modified polystyrene foam heat preservation board on the basis, an air isolation cover is formed around the polystyrene particles, a part of components is evaporated and carries away a large amount of heat after the fireproof material encounters open fire to be heated, the left component carbonized crystal forms a framework, the integrity of the fireproof modified polystyrene foam heat preservation board is ensured within a time period, the defect that the polystyrene particles are inflammable in case of fire is thoroughly overcome, and physical performance is improved.

Description

technical field [0001] The invention relates to the technical field of building insulation materials, in particular to a fireproof modified polystyrene foam insulation board and a manufacturing method thereof. Background technique [0002] The full name of polystyrene foam board, referred to as EPS board, is currently the most widely used building insulation material on the market. It is made of expandable polystyrene particles containing volatile liquid foaming agent, heated and pre-expanded, and then heated in a mold to form a white solid with a fine closed-cell structure. EPS board can effectively protect the wall, has high strength, long durability, good thermal insulation performance, low cost, simple construction, and convenient maintenance. Therefore, it is widely used as a good thermal insulation material in wall thermal insulation systems. However, the fire resistance of traditional EPS boards is poor, and it is a flammable material. It melts, shrinks, and flows im...

Problems solved by technology

[0016] The technical problem to be solved by the present invention is: in order to solve the problem that traditional EPS boards are flammable and produce poisonous gas and dense smoke when burned, and aim at the current existing fireproof EPS boards, although the fireproof performance has been improved, but in terms of thermal insulation performance, bulk density, etc. To improve the poor performance in terms of water absorption and water absorption, the present invention provides a fireproof modified polystyrene foam insulation board, which combines flammable polystyrene and air Solve the above problems by isolating and preventing its burning
