High-temperature-resistant and corrosion-resistant ABS particles and preparation method thereof

Abstract

The invention discloses high-temperature-resistant and corrosion-resistant ABS particles and a preparation method thereof. The ABS particles are prepared from the following raw materials in parts by weight: 8-10 parts of precipitated calcium carbonate, 8-10 parts of calcined clay, 8-10 parts of talcum powder, 30-40 parts of styrene, 30-40 parts of a modified heat-resistant agent, 3-4 parts of benzoyl peroxide, 80-100 parts of ABS resin, 20-25 parts of polypropylene and 5-8 parts of a lubricant. In the preparation process, the polypropylene and the ABS resin are blended, so that the corrosion resistance of the ABS resin is enhanced. The modified heat-resistant agent is prepared, molecules of the modified heat-resistant agent have a plurality of five-membered ring structures, each five-membered ring structure is connected with a benzene ring, the five-membered rings and the benzene rings are groups with high rigidity and can well hinder internal rotation of chain segments, so that the rigidity of the high-molecular polymer is improved, and the heat resistance of the high-molecular polymer is further improved.

Description

technical field [0001] The invention belongs to the field of plastic preparation, and in particular relates to high-temperature-resistant and corrosion-resistant ABS particles and a preparation method thereof. Background technique [0002] ABS plastic is a terpolymer of acrylonitrile-butadiene-styrene. It combines the properties of three components, among which acrylonitrile has high hardness and strength, heat resistance and corrosion resistance, butadiene has impact resistance and toughness, and styrene has high surface gloss, easy coloring and Ease of processing, the characteristics of the above three components make ABS plastic a thermoplastic with good comprehensive performance of "hard quality, toughness and high rigidity". However, after actual use, it is found that ABS products are not resistant to sulfuric acid corrosion Sulfuric acid will be crushed and broken, and it will be damaged when used at a temperature higher than 100°C, which seriously affects the scope o...

[0003] Chinese invention patent CN107573635A discloses a high-performance flame-retardant ABS material and its preparation method. The ABS material is made of the following raw materials in parts by weight: ABS resin 50-100 parts, transition metal compound 5-10 parts, auxiliary flame retardant 1 -10 parts, 1-20 parts of lubricant, the ABS material prepared by the invention has good flame retardant effect and excellent mechanical properties, but the corrosion resistance of the ABS material is relatively poor, and it will break into pulverization when it encounters sulfuric acid. The ABS material has been damaged under high temperature conditions, which is not conducive to the multi-field use of ABS materials
