Abstract

The invention discloses a preparation method of a sol deposition hollow polystyrene building insulation material. According to the preparation method disclosed by the invention, hollow sol deposition calcium carbonate filler is epoxidized, then is blended with an amination styrene monomer, and participates in a polymerization reaction of styrene, so that the compatibility of the filler among polymers is effectively improved, agglomeration is effectively reduced, and the stability and the strength of a finished material are improved. A composite material disclosed by the invention has the advantages of good flame retardance, heat insulation property, corrosion resistance, stability, strength and the like, light weight, good environment-friendly property and excellent overall properties.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of a sol-deposited hollow polystyrene building insulation material. Background technique [0002] Polystyrene foam is a lightweight material made of polystyrene resin as the base material, adding foaming agent and other auxiliary materials, and foaming by heating. It has the advantages of light weight, small thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price and high quality. However, polystyrene foam insulation materials bring great convenience to people's lives. Flammability also brings certain limitations to its application. Polystyrene foam itself is a flammable material, and it is easy to decompose and burn under fire and high temperature conditions. [0003] And accompanied by a large amount of toxic gas. Therefore, it is urgent to carry out research work on the f...
