Abstract

The invention discloses a nanometer environmentally friendly pbt material. The nanometer environmentally friendly pbt material comprises, by weight, 92-100 parts of polybutylene terephthalate, 0.7-1 part of methyl ethyl ketone oxime, 1-2 parts of tricalcium silicate, 1-2 parts of butylmercaptooxo stannane, 1-2 parts of sebacic dihydrazide, 1-2 parts of polyhexamethylene guanidine, 1-2 parts of sodium fluoride, 2-4 parts of nanometer brick slag powder, 1-2 parts of aluminum dihydrogen phosphate, 1-2 parts of molybdenum boride, 2-3 parts of phosphate ester, 2-4 parts of dioctyl phthalate, 0.1-0.2 part of cross-linking agents TAC and 1-2 parts of processing agents. The nanometer environmentally friendly pbt material is good in environmental protection performance, compatibility among the materials is well promoted due to the added nanometer materials, and the comprehensive performance of products is increased. The finished product is good in anti-abrasion performance and tensile resistance, high in heat resistance and acid and alkali resistance, wide in application range and good in safety and environmental protection performance.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a nano-environmental friendly PBT material. Background technique [0002] Polybutylene terephthalate has low weather resistance and water absorption rate of only 0.1%. It still maintains various physical properties (including electrical properties) and electrical insulation in a humid environment, but its volume resistance and dielectric loss are large. Resistant to hot water, alkalis, acids, oils, but easily corroded by halogenated hydrocarbons, poor hydrolysis resistance, rapid crystallization at low temperature, good formability. The disadvantage is that the notched impact strength is low and the molding shrinkage is large. Therefore, most of them are reinforced by glass fiber or modified by inorganic filling, the tensile strength and bending strength can be more than doubled, and the heat distortion temperature is also greatly increased. It can work at 140°C for a long t...
