Embodiment 1

[0031] Each component is weighed according to the parts by weight of each component in Table 1, wherein the percentage of acrylonitrile in ABS is 22%-30%, and the percentage of butadiene is 15%-20%. Dry the ABS at 80°C~90°C for 2~3h and then cool to room temperature. Fully mix DMDBP and silane, then add ABS, aluminum hydroxide, antioxidant, catalyst and other additives together with the above mixed liquid into the high-speed mixer, and mix thoroughly. Wherein the silane coupling agent is γ-methacryloxypropyltrimethoxysilane (VMMS, KH570).

Embodiment 2

[0033] Each component is weighed according to the parts by weight of each component in Table 1, wherein the percentage of acrylonitrile in ABS is 22%-30%, and the percentage of butadiene is 15%-20%. Dry the ABS at 80°C~90°C for 2~3h and then cool to room temperature. Fully mix DMDBP and silane, then add ABS, aluminum hydroxide, antioxidant, catalyst and other additives together with the above mixed liquid into the high-speed mixer, and mix thoroughly. The silane coupling agent is vinyltriethoxysilane (VTES, A151).

Embodiment 3

[0035] Each component is weighed according to the parts by weight of each component in Table 1, wherein the percentage of acrylonitrile in ABS is 22%-30%, and the percentage of butadiene is 15%-20%. Dry the ABS at 80°C~90°C for 2~3h and then cool to room temperature. Fully mix DMDBP and silane, then add ABS, aluminum hydroxide, antioxidant, catalyst and other additives together with the above mixed liquid into the high-speed mixer, and mix thoroughly. Wherein the silane coupling agent is vinyltrimethoxysilane (VTMS, A171).

Abstract

The invention provides a grafting-modified ABS anti-static material and a preparation method thereof, and relates to a high polymer material and a preparation method thereof. According to the grafting-modified ABS anti-static material and the preparation method thereof, a one-step crosslinking technology is adopted, an assistant crosslinking agent is added, water molecules needed by crosslinking can be obtained in the extruding processing process, and the hot water treating process after grafting is omitted, so that a grafting material can automatically complete a crosslinking reaction at room temperature; through enhancement modification, the good mechanical property is achieved, and meanwhile the excellent anti-static property is achieved; the preparation technology is simple, and the product cost is low. The anti-static ABS material can be processed into parts in various shapes through injection molding and is particularly suitable for being processed into various automotive interior parts through injection molding.

Description

technical field [0001] The invention relates to a polymer material and a preparation method thereof, in particular to a graft modified ABS antistatic material and a preparation method thereof. Background technique [0002] ABS resin (acrylonitrile-styrene-butadiene copolymer, ABS is the acronym for AcrylonitrileButadieneStyrene) is a thermoplastic polymer material structure with high strength, good toughness and easy processing. ABS resin is a graft copolymer of three monomers of acrylonitrile, 1,3-butadiene and styrene. Its molecular formula can be written as (C 8 h 8 ·C 4 h 6 ·C 3 h 3 N) x , but in fact it is often a mixture of graft copolymers containing butadiene and acrylonitrile-styrene copolymers, of which acrylonitrile accounts for 15-35%, butadiene accounts for 5-30%, and styrene accounts for 40-30%. 60%, the most common ratio of emulsion method ABS is A:B:S=22:17:61, while the ratio of B in bulk method ABS is often lower, about 13%. ABS is a thermoplastic ...
