Abstract

The invention discloses a glass fiber reinforced AES resin material and a preparation method thereof. The glass fiber reinforced AES resin material is prepared from the following ingredients in parts by weight: 50-90 parts of acrylonitrile-ethylene propylene diene rubber-styrene, 10-40 parts of glass fibers, 3-10 parts of compatibilizer, 0.5-2 parts of coupling agent and 1-5 parts of dimethyl itaconate. The glass fiber reinforced AES resin material prepared by the preparation method has excellent tensile and bending properties and balanced flowability and impact properties. Due to the use of the glass fibers, the cost of the AES material is reduced, and the range of use of the AES material can be wider. The preparation method disclosed by the invention is simple and easy to implement. According to the glass fiber reinforced AES resin material and the preparation method thereof, a synergetic effect is achieved among the added dimethyl itaconate, the compatibilizer SMA (styrene-maleic anhydride copolymer) and the coupling agent, and the interfacial bonding strength between the AES and the glass fibers can be maximized, so that the mechanical properties of the material can be improved, and particularly the impact resistance of the material can be improved greatly.

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 resin, also known as EPSAN resin, is a graft copolymer of EPDM rubber, styrene and acrylonitrile. Like ASA and ACS, it is a styrene-based toughening resin developed for the poor weather resistance of ABS. 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 better than ABS resin, and other properties are equivalent to ABS. Therefore, due to its good comprehensive performance and excellent weather resistance, AES resin is now gradually used in auto parts, fishery and agricultural turnover boxes, and also has certain ...
