Axial-flow fan blade high-flow glass fiber reinforced flame-retardant AS special material and preparation method thereof

Abstract

The invention discloses an axial-flow fan blade high-flow glass fiber reinforced flame-retardant AS special material and a preparation method thereof. The AS special material is prepared from, by weight, 34-52% of an acrylonitrile-styrene copolymer, 20% of an alkali-free glass fiber, 3-6%of a compatilizer, 15-22% of a flame retardant, 3-6% of a flame retardant synergist, 0.1-0.5% of an efficient lubricant and 0.2-1% of an antioxidant. The AS special material provided by the invention is based on base material selection, an AS raw material with narrow molecular weight distribution and high acrylonitrile content is selected, the acrylonitrile-styrene copolymer of the type has high rigidity, proper fluidity and stable mechanical properties, the glass fiber is the alkali-free glass fiber of which the surface is coated with a silane-based impregnating compound, the glass fiber has the characteristics of high strength, high surface activity and good compatibility with a base material, the flame retardant decabromodiphenyl ethane which has excellent compatibility with the base material and high flame retardant efficiency is selected, so the flame retardant level of the AS special materialreaches UL94 test standard.

Description

technical field [0001] The invention relates to a plastic, in particular to a high-flow glass fiber reinforced flame-retardant AS special material for an axial-flow fan blade and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the continuous improvement of the society's requirements for the use of air-conditioning products, the competition in the air-conditioning market is becoming more and more fierce. [0003] ASGF materials are widely used in the manufacture of fan blades for air conditioners and exhaust systems in some occasions. The air conditioner technology used in daily environments is very mature, but the development of air conditioner fan blades used in some special environments is still in its infancy. For example, in some special closed environments such as flammable and explosive, it is required to avoid the risk of fire in the process of using the fan blades, which will pose a great threat to property an...

AI Technical Summary

Problems solved by technology

Since the AS fiber-reinforced material itself is a brittle material, and the flame retardant function is added to the material, it is necessary to add a flame retardant with a flame retardant effect to the original reinforcement system, and the addition amount is also large. Therefore, the compatibility problem between the various components in the system must be solved, otherwise the material cannot meet the use requirements of the fan blade in a special environment.
