A class A fireproof heat insulation polystyrene foam particle and its processing method

Abstract

The invention relates to a material structure and a processing method of thermal insulation polystyrene foam particles with A-level fireproof function. Specifically, it is made of ordinary commercially available polystyrene foam particles, which are modified by three layers of different composite additives; the spherical surface of ordinary commercially available polystyrene foam particles is used as the original first core. layer, on the outside of the first core inner layer, wrap the second fireproof middle layer coated with a layer of nanocomposite fireproof additive, and then wrap and roll a layer of nanocomposite combustion additive on the outside of the second fireproof middle layer The third cured outer layer, and finally, on the outside of the third cured outer layer, wrap and spray the fourth toughened surface layer with a layer of nanocomposite toughening additive; these four layers are wrapped and covered in layers according to the order of inside, middle and outside. Modification, interaction, and composition as a whole.

Description

technical field [0001] The invention relates to new building material technology and the application field of energy saving and emission reduction, in particular to a heat-insulating polystyrene foam particle with A-level fireproof function and a processing method thereof. Background technique [0002] At present, energy conservation and emission reduction, low-carbon environmental protection, have become an important topic and strategic task common to all mankind, and the energy consumption of buildings is very large, accounting for more than half of the total energy consumption. Building insulation is an effective means to solve building energy consumption and necessary condition. [0003] In comparison, expandable polystyrene foam particles are currently the most cost-effective thermal insulation material. The only disadvantage is that it is flammable and not fireproof, which has caused many catastrophic fire accidents and seriously affected its application. So much so t...

Problems solved by technology

[0003] In comparison, expandable polystyrene foam particles are currently the most cost-effective thermal insulation material. The only disadvantage is that it is flammable and not fireproof, which has caused many catastrophic fire accidents and seriously affected its application. So much so that its use is completely banned because of choking and waste food, causing a large number of existing polystyrene foam processing factories to close down
