Embodiment 1

[0021] Pour 57.5g of measured deionized water into the dispersion tank and start stirring at a low speed, slowly add 0.85g of light stabilizer 5411 weighed to dissolve, and then add 0.65g of polyacrylic acid after it is completely dissolved Stir the methyl ester for 20 minutes, then slowly add 5.5g of zinc stearate weighed, after the zinc stearate is completely dissolved, slowly add 23.5g of antioxidant WL and 12.0g of antioxidant 3052 respectively Increase the stirring speed and stir vigorously for about 10 minutes, then reduce the speed and continue stirring for 30 minutes to obtain a preliminary dispersion. After the preliminary dispersion is ground by a sand mill and then filtered through a filter, it is the required ABS resin composite antioxidant.

Embodiment 2

[0023] Pour 53.0g of measured deionized water into the dispersion tank and start stirring at a low speed, slowly add 1.2g of light stabilizer 770 weighed to dissolve, and then add 0.3g of silicone oil weighed and stir After 10 minutes, slowly add 5.5g of the weighed glycol fatty acid ester, and slowly add the weighed antioxidant WL 25.5g and antioxidant 3052 14.5g after the glycol fatty acid ester is completely dissolved Then increase the stirring speed and stir vigorously for about 5 minutes, then reduce the speed and continue stirring for 20 minutes to obtain a preliminary dispersion. After the preliminary dispersion is ground by a sand mill and then filtered through a filter screen, it is the required ABS resin composite antioxidant. .

Embodiment 3

[0025] Pour 55.5g of measured deionized water into the dispersion tank and start stirring at a low speed, slowly add 0.8g of light stabilizer 5411 weighed to dissolve, and then add 0.2g of palmitic acid after it is completely dissolved After the isopropyl ester is stirred for 30 minutes, slowly add 5.5g of dipentaerythritol ester that has been weighed. After the dipentaerythritol ester is completely dissolved, slowly add 22.5g of antioxidant WL and 15.5g of antioxidant 3052 respectively, and then speed up. Stir vigorously at the stirring speed for about 15 minutes, then reduce the rotating speed and continue stirring for 40 minutes to obtain a preliminary dispersion. After the preliminary dispersion is ground by a sand mill and then filtered through a filter screen, it is the required ABS resin composite antioxidant.

Abstract

The invention discloses an ABS resin composite antioxidant and a preparation method thereof, and relates to the field of antioxidants, the ABS resin composite antioxidant comprises 20%-35% of a main antioxidant, 10%-20% of an auxiliary antioxidant, 5%-15% of a dispersant, 0.5%-1.5% of a stabilizer, 0.2%-0.5% of an antifoaming agent, and the balance deionized water. A bisphenol monoester auxiliary antioxidant, a main antioxidant, a dispersing agent, a stabilizing agent, a defoaming agent and the like are compounded and processed to prepare a novel additive, and the novel additive can be uniformly dispersed in acrylonitrile/butadiene/styrene terpolymer (ABS) latex, so that the auxiliary adding step is simplified, and the mixing effect of the antioxidant and the latex is improved; and the oxidation induction period of the antioxidant in the ABS latex is prolonged by about 10%. The emulsion-type ABS antioxidant is convenient to use and can be directly added into ABS latex, so that the emulsion can be fully mixed, the production steps can be simplified, and meanwhile, the production cost of the device is reduced.

Description

technical field [0001] The invention relates to the field of antioxidants, in particular to an ABS resin composite antioxidant. Background technique [0002] ABS resin is a copolymer of three monomers of acrylonitrile-butadiene-styrene. It is an important polymer material with high strength, good toughness and easy processing. It has great potential in the fields of automobiles, electrical appliances, building materials and machinery. Wide range of applications. [0003] As a kind of chemical auxiliary agent, antioxidant plays a vital role in improving the performance and quality of ABS resin products in the production process of ABS resin. When it only exists in a small amount in the ABS resin, it can delay or inhibit the oxidation process of the ABS resin, solve the problems of brown, yellowing, hardening, cracking, etc., and at the same time maintain the mechanical properties of the material such as impact strength and elongation. , so as to prevent the aging of ABS res...
