Low-fragrance low-organosilicon glass fiber reinforced PBT material and preparation technology thereof

Abstract

The invention discloses a low-fragrance low-organosilicon glass fiber reinforced PBT material and a preparation technology thereof. The low-fragrance low-organosilicon glass fiber reinforced PBT material is prepared from the following raw materials in parts by weight: 40-50 parts of PBT resin, 4-8 parts of glass fiber, 3-5 parts of antistatic agents, 2-6 parts of coupling agents, 4-8 parts of silicon oil, 2-6 parts of antioxygen, 1-5 parts of fire retardants, 4-8 parts of dispersing agents, 3-6 parts of toughening agents, 4-8 parts of lead caprylate, 2-6 parts of disodium hydrogen phosphate, 1-3 parts of sodium dehydroacetate and 2-4 parts of dimethyl fumarate. The preparation technology comprises the following steps that S1, a set of weighing equipment is selected, stearamide and higher alcohol raw materials are weighed by weight, and the weighted stearamide and higher alcohol raw materials are placed into an anti-corrosion container. According to the low-fragrance low-organosilicon glass fiber reinforced PBT material and the preparation technology thereof, the design is reasonable, decabromodiphenyl ether, titanate and other addition agents are added into the raw materials, the heat stability, antibacterial property, oxidation resistance and flame retardant property for preparing the low-fragrance low-organosilicon glass fiber reinforced PBT material are effectively improved,and the safety of the PBT material is enhanced.

Description

technical field [0001] The invention relates to the technical field of PBT material processing, in particular to a low-aromatic and low-organic-silicon glass fiber reinforced PBT material and a preparation process thereof. Background technique [0002] PBT (polybutylene terephthalate) material not only has excellent physical and mechanical properties such as high mechanical strength, good fatigue resistance and dimensional stability, and excellent aging resistance, but also has excellent electrical properties, such as its volume resistance High rate and dielectric strength, excellent arc resistance, and stable electrical properties in humid and high temperature environments, so PBT material is an ideal material for manufacturing electronic and electrical parts. PBT material is a cost-effective engineering plastic. It is more and more widely used in public places. [0003] After retrieval, the patent document with the application number 201110044217.9 discloses a halogen-fre...

AI Technical Summary

Problems solved by technology

However, the existing PBT materials still have low flame retardancy and poor thermal stability, which makes the safety of PBT materials insufficient and limits the application range of PBT materials. Therefore, we propose a low-aromatic and low-organosilicon glass fiber-reinforced PBT material and Its preparation process is used to solve the above problems
