Glass fiber reinforced flame-retardant ABS 5VA material for fan blades and preparation method of material

Abstract

The invention discloses a glass fiber reinforced flame-retardant ABS 5VA material for fan blades and a preparation method of the material. The glass fiber reinforced flame-retardant ABS 5VA material for fan blades is prepared from components in percentage by mass as follows: 40%-70% of ABS resin, 15%-20% of a flame retardant, 1%-3% of an SMA resin, 0.2%-0.4% of a lubricating dispersant, 0.2%-0.4%of an anti-dripping agent, 0.1%-0.3% of an antioxidant and 10%-30% of alkali-free continuous glass fiber. The glass fiber reinforced flame-retardant ABS 5VA material for fan blades has the characteristics of good rigidity and strength, improved fluidity and mold filling capacity, low cost and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a glass fiber reinforced flame-retardant ABS 5VA material for wind blades and a preparation method thereof. Background technique [0002] At present, in addition to the use of a certain amount of metal materials such as copper and steel, plastic parts account for most of the parts of air conditioners, especially the wind blade materials of air conditioners. The existing wind blades are mainly reinforced with glass fiber. It is made of AS or ABS, among which glass fiber reinforced ABS has better impact resistance and processing performance, so glass fiber reinforced ABS is commonly used. [0003] The glass fiber reinforced ABS material used for wind blades is injected in the blade mold. It is required that the injection mold filling is normal, there is no shortage of materials, no sticking and cracking; and ABS for wind blades usually requires tensile tests, torsion tests, and dyn...

Problems solved by technology

[0004] Chinese Patent Document No. CN 103740082 discloses a UL94-5VA grade flame retardant reinforced PC / ABS blend material by adding carbon fiber, which reaches UL94-5VA under the thickness of 2.0mm, and the sample has no damage under the repeated action of the flame. Twisted, no perforation, maintains a relatively complete appearance shape, but carbon fiber is expensive, and PC / ABS reinforced with carbon fiber has poor fluidity, which is not conducive to injection molding

Chinese Patent Document No. CN 106633525 discloses a weather-resistant high-impact PVC / ABS composite 5VA material, but PVC / ABS has poor temperature resistance and low rigidity, which cannot meet the requirements of wind blade materials

[0005] Under normal circumstances, after the flame-retardant modification of glass fiber reinforced ABS, the tensile strength and impact toughness will drop more, and the fluidity will decrease, resulting in the failure of the tensile, torsion and drop tests of the wind blade parts, and the injection molding and filling mold Reduced capacity; ordinary glass fiber reinforced ABS belongs to UL94-HB level, flammable, poor fire safety performance
