Abstract

A light-weight bacteriostatic building thermal-insulation material is disclosed. The thermal-insulation material is prepared from, by weight, a proper amount of polyvinylpyrrolidone, 100-120 parts of an aqueous silver nitrate solution having a concentration of 3-5%, 27-30 parts of ethyl orthosilicate, 3-4 parts of sericin, 2-3 parts of tributyltetradecylphosphonium chloride, 1-2 parts of pentaerythritol, a proper amount of ammonia water, 0.4-1 part of divinyl benzene, 0.2-0.3 part of Span 80, 3-5 parts of 1,3,5-triglycidyl isocyanurate, 180-200 parts of styrene, 0.1-0.2 part of hexadecyldimethylamine, 7-10 parts of ammonium persulfate, 5-6 parts of stannous octoate, 16-20 parts of a pentane foaming agent, a proper amount of glycol and a proper amount of dimethylformamide. The thermal-insulation material has good flame retardance, thermal insulation performance, bacteriostatic performance, and a light weight, and is convenient to mount and transport.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a lightweight antibacterial building insulation material and a preparation method thereof. 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...
