High-temperature-resistant composite material with good antistatic property and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant composite material with a good antistatic property and a preparation method thereof. The high-temperature-resistant composite material is preparedfrom the following raw materials in parts by weight: 23-32 parts of polybutylene terephthalate, 14-20 parts of nylon, 10-18 parts of polyformaldehyde, 3.6-7.5 parts of nano silicon dioxide, 3-5 partsof aluminum dihydrogen phosphate, 4.2-6 parts of glass fibers, 4-8 parts of gelatin, 4-6.6 parts of antistatic masterbatch, 15-24 parts of butyl pentylalcohol and 5.5-8.4 parts of plant oil. The composite material is wide in source of raw materials, simple in preparation process and suitable for being industrially produced on a large scale. Under the synergistic effect of the raw materials, the prepared product not only has good using strength and high resistivity at a constant temperature, but also can keep relatively good using strength and relatively high resistivity in a high temperature environment of over 160 DEG C, so that the antistatic and high-temperature using demands can be met.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a composite material with good high temperature resistance and antistatic performance. Background technique [0002] Static electricity is a charge that is at rest. Static electricity is formed when charges accumulate on an object or surface, and charges are divided into positive charges and negative charges, that is to say, static electricity is also divided into two types, namely positive static electricity and negative static electricity. Positive static electricity is formed when positive charges accumulate on an object, and negative static electricity is formed when negative charges accumulate on an object. In the dry and windy autumn, people often encounter this phenomenon in daily life: when they take off their clothes to sleep at night, they often hear the crackling sound in the dark, accompanied by blue light; The other party will suddenly feel tingling pain like fin...

Problems solved by technology

[0003] In recent years, with the deepening of people's understanding of electrostatic hazards, anti-static has become more and more important, especially for semiconductor products, highly integrated precision electronic components, composition and precision instruments and equipment, medical equipment and chemical products, etc. , During the transfer process, due to the influence of friction, impact, external electric field and magnetic field, it is easy to generate static electricity, electrostatic dust collection will affect the performance of the product, and the accumulation of static electricity will generate discharge under suitable conditions, causing product and equipment failure or component damage , may cause great economic losses. People have developed anti-static materials, but the anti-static properties of existing anti-static materials are greatly reduced at high temperatures, which limits the application of anti-static materials.
