Problems solved by technology

[0003] However, the strength of the modified AES resin currently developed is low, which restricts its application in more fields
With the expansion of AES application fields, pure AES mechanical properties will be insufficient in the field of high strength requirements, and the cost of AES materials restricts its wide application

Abstract

The invention discloses a glass fiber-reinforced AES resin material. The glass fiber-reinforced AES resin material is prepared from 50-90 parts by weight of acrylonitrile-ethylene propylene diene monomer-styrene (AES), 10-40 parts by weight of glass fibers, 3-10 parts by weight of a compatilizer, 0.5-2 parts by weight of a coupling agent and 0.5-5 parts by weight of tributyl citrate. The glass fiber-reinforced AES resin material has excellent stretching and bending performances and balanced fluidity and impact resistance. The glass fibers reduce an AES material cost so that the AES material has a wide use range. Through synergism of the tributyl citrate, compatilizer SMA and coupling agent, an interface bonding force of AES and glass fibers is maximized so that material mechanical properties are improved and shock resistance is greatly improved. The preparation method has simple processes and can be implemented easily.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a glass fiber reinforced AES resin material and a preparation method thereof. Background technique [0002] AES (acrylonitrile-EPDM-styrene) resin, also known as EPSAN resin, is a graft copolymer of EPDM rubber, styrene and acrylonitrile. Like ASA (acrylonitrile-acrylonitrile-styrene copolymer) and ACS (acrylonitrile-chlorinated polyethylene-styrene copolymer), it is also aimed at the poor weather resistance of ABS (acrylonitrile-butadiene-styrene copolymer) And developed a styrene-based toughening resin. AES uses EPDM rubber as a toughening agent. EPDM is an ethylene-propylene-diene terpolymer with very little double bond content in its molecule. Therefore, the weather resistance of AES is 4-8 times better than that of ABS. In addition, the thermal stability, water absorption and impact strength of AES are superior to ABS resin, and other properties are equivalent to ABS. The...
