A kind of antistatic molding composition containing conductive glass fiber and its preparation method

Abstract

The present invention discloses an antistatic molding composition comprising conductive fiberglass. The composition comprises, by weight percentage, the following: 35-75% of a resin, 20-55% of conductive fiberglass, 2-30% of an impact modifier, 0.5-30% of a flame retardant, 0.2-3% of an anti-drip agent, 0.05-1% of a lubricant, and 0.05-1% of a pigment, wherein the resin is a polycarbonate resin or a polyestercarbonate resin, and a component B may be fiberglass having a conductive sol-gel antimony-doped tin oxide coating layer on an outer surface thereof. The present invention also discloses a method of preparing the antistatic molding composition comprising conductive fiberglass. The antistatic molding composition prepared by the present invention can achieve a permanent antistatic effect, and has the following benefits: easy to be colored, having an aesthetically-pleasing appearance, employing well-chosen materials, having a scientific production process, easy to prepare, having a low cost, long service life, and wide applicability, and suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antistatic molding composition containing conductive glass fibers and a preparation method thereof. Background technique [0002] With the development of technology and people's increasing attention to the comfort of the home environment, high-end smart small appliances and smart home systems are becoming more and more popular. Emerging small household appliances, such as intelligent sweeping robots, wireless vacuum cleaners, etc., require materials with excellent Conductive (antistatic) or antistatic. [0003] Traditional permanent antistatic materials generally use permanent antistatic agents or carbon fibers to achieve permanent antistatic effects. Permanent antistatic agent, such as MH2030 from Arkema, France, is a kind of additive with special polyether chain segment based on polyamide. Generally, this kind of antistatic agent is sensitive to environmental h...

Problems solved by technology

Permanent antistatic agent, such as MH2030 from Arkema, France, is a kind of additive with special polyether chain segment based on polyamide. Generally, this kind of antistatic agent is sensitive to environmental humidity, that is, high humidity antistatic The effect is good, and vice versa; and this type of antistatic agent is not easy to color due to its own characteristics, it is difficult to make bright colors, or injection molding defects that are prone to weld marks during the injection molding process affect the appearance experience

Carbon fiber is used to achieve permanent antistatic effect. Due to the color limitation of carbon fiber, the appearance of the product is black, and the color effect cannot be achieved.
