Heat-preservation pbt material and preparing method thereof

Abstract

The invention discloses a heat-preservation pbt material.The heat-preservation pbt material is prepared from, by weight, 3-4 parts of scolecite, 3-5 parts of an alkyl ketene dimer, 70-80 parts of caprolactam, 10-13 parts of attapulgite, 1-1.4 parts of zinc acetate, 2-3 parts of gamma-aminopropyltriethoxysilane, 18-20 parts of oxalic acid, 300-370 parts of polybutylene terephthalate, 1-2 parts of fatty alcohol polyoxyethylen ether, 10-14 parts of dimethyl isophthalate, 2-3 parts of ammonium aluminum sulfate, 2-3 parts of tert-butyl hydroquine, 1-2 parts of borax, 2-4 parts of trichloroiminocyanuric acid and 1-2 parts of polystyrene.According to the heat-preservation pbt material, scolecite is added, micropores can be formed in the material, and thus very good heat preservation and heat insulation effects are achieved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a thermal insulation PBT material and a preparation method thereof. Background technique [0002] As a photocatalytic antibacterial agent, ZnO has been widely studied in recent years, and it generates strong oxidative active functional groups under the action of photocatalysis to kill bacteria. It has the advantages of non-toxic, non-irritating, good stability, difficult to decompose under high temperature, long-lasting, low price, rich resources, etc., and has broad application prospects; [0003] At present, the commonly used carriers for loading photocatalysts mainly include carbon nanotubes (CNTs) and activated carbon, mesoporous materials, white carbon black and zeolite, etc. By loading, nanoparticles with uniform size can be obtained, and at the same time, the nano-functional composite materials can be guaranteed. high stability. The nano-photocatalyst / porous mineral co...

Problems solved by technology

However, during the application process, the polar groups of the polyamide 6 material make it easy to absorb water, resulting in low dry and low temperature impact strength, poor product stability, easy plastic deformation due to friction, and severe wear. In addition, as a mine The use of engineering plastics does not have antistatic properties and is prone to gas explosions, etc., which affects the dimensional stability, anti-wear and anti-friction properties and electrical properties of its products, which limits its application range;
