High-gloss high-heat-resistance high-fluidity halogen-free flame-retardant glass-fiber-reinforced PC material and preparation method thereof

Abstract

The invention provides a high-gloss high-heat-resistance high-fluidity halogen-free flame-retardant glass-fiber-reinforced PC material and a preparation method thereof. The material is composed of the components of, by weight, 50-80 parts of polycarbonate, 0-15 parts of an inorganic flame retardant, 1-6 parts of halogen-free flame retardant masterbatch, 3-10 parts of a compatibilizing agent, 0.2-3 parts of a lubricant, 0.1-0.4 parts of an antioxidant, 0.1-0.3 parts of an anti-dripping agent, 5-30 parts of glass fiber, and 0.2-1 parts of other auxiliary agents. According to the preparation method, dried PC, the compatibilizing agent and the auxiliary agents are mixed in a high-speed mixer according to a certain ratio; when the materials are uniformly mixed, the mixture is added into a twin-screw extruder, and is subjected to kneading and extrusion with continuously inputted glass fiber. According to the invention, the requirements on high-efficiency halogen-free flame retarding property and environment friendliness are realized. Under a specific process environment, the product has relatively high gloss, and can be widely applied in home appliances, LCD televisions and tablet computers.

Description

technical field [0001] The invention belongs to the field of materials, and specifically relates to a halogen-free flame retardant, high gloss, low shrinkage, high fluidity, high heat resistance, and high rigidity, which is suitable for computers, TV front shells and middle rubber frames. Flame retardant glass fiber reinforced PC alloy material. Background technique [0002] With the improvement of people's living standards, the demand for home appliances in the market is getting higher and higher, and plastic products are widely used. Flat-panel TVs and computers have become new favorites of home appliances due to their lightness and thinness. Because ABS and PS are cheap and have relatively high gloss, they have been used as main products, but their hardness is low, they cannot meet the requirements of thin-walled products, and cannot protect the liquid crystal screen. Therefore, the present invention Provides a halogen-free flame-retardant glass fiber reinforced PC produ...

Problems solved by technology

But at the same time, because PC products have poor fluidity, are prone to environmental stress cracking, and are sensitive to notch damage, there are many difficulties in the production and processing process.
