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.

Embodiment 1

[0045] Weigh 4.2kg of component A1, 4.0kg of component B1, 0.5kg of component C, 1.25kg of component D, 0.02kg of component E, 0.02kg of component F, and 0.01kg of red pigment. The mixer is mixed evenly, and the speed of the high-speed mixer is set at 1400r / min. It is melted and extruded through a twin-screw or single-screw extruder, and the extrusion temperature is 230-300°C; and then pelletized by a granulator to produce pellets. Dry in an oven at 80° C. for 4 hours, and then obtain a sample strip with a thickness of 1.6 mm by injection molding. The temperature of the injection molding machine is set at 270° C., and the injection molding pressure is 70-120 bar.

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...
