preparation example Construction

[0039] A preparation method for ABS toughening agent, comprising the following steps:

[0040] 1) Mix the ABS high rubber powder, compatibilizer, reinforcing agent, dispersant, polyhydroxy chemical coupling agent and antioxidant in the formula amount, and stir evenly to obtain the mixture;

[0041] 2) the compound is placed in the internal mixer, fully plasticized, to obtain a semi-finished product;

[0042] 3) Take the semi-finished product, cool it to room temperature, then pulverize it and sieve it.

Embodiment 1

[0044] An ABS toughening agent is prepared according to the following steps: Weigh 68.5 parts of ABS high-glue powder, 20 parts of ABS-g-MAH, 5 parts of organic montmorillonite, 3 parts of barium stearate, 2 parts of zinc stearate 1 part of pentaerythritol, 0.5 part of tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester. Put the above-mentioned ingredients into a high-speed mixer and mix them well; then put them in a double-roller internal mixer and knead them for 8 minutes, and set the kneading temperature to 230°C; Crush and screen the ABS toughening agent below 2mm for performance test.

[0045] The test method is as follows: the test indicators include notched impact strength (kJ / m 2), melt index (g / 10min), tensile strength (MPa), elongation at break (%), flexural strength (MPa) and modulus of elasticity (MPa), the test standards are strictly in accordance with ISO180, ISO 1133, ISO 1033, ISO 527, ISO 178 and other systems for verification. ...

Embodiment 2

[0051] An ABS toughening agent is prepared according to the following steps: Weigh 57.5 parts of ABS high rubber powder, 15 parts of ABS-g-MAH, 10 parts of AS-g-MAH, 10 parts of fumed nano-silica, ethylene bis 5 parts of stearamide, 2 parts of glycerin, 0.5 part of tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester. Put the above-mentioned ingredients into a high-speed mixer, and stir well; then put them in a double-roller mixer for 10 minutes, and set the mixing temperature to 220°C; Crush and screen the ABS toughening agent below 2mm for performance test.

[0052] The test method is the same as in Example 1, and the test results are shown in Table 2 below.

Abstract

The invention discloses an ABS (acrylonitrile-butadiene-styrene) flexibilizer. The ABS flexibilizer comprises components in parts by weight as follows: 60-90 parts of high rubber content ABS, 10-30 parts of a compatilizer, 1-10 parts of a reinforcing agent, 1-10 parts of a dispersing agent, 0.5-3 parts of a polyhydroxyl chemical coupling agent and 0.5-2 parts of an antioxidant. According to the ABS flexibilizer, solubility parameters of high rubber content ABS can be increased, compatibility of high rubber content ABS with ABS resin is better, so that reduction of overall performance of resin due to phase layering is slowed down and more efficient toughening effect is realized. The invention further discloses a preparation method of the ABS flexibilizer. The preparation method adopts a few steps, and is simple to operate, convenient and safe.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an ABS toughening agent and a preparation method thereof. Background technique [0002] ABS resin is polymerized from monomers acrylonitrile, butadiene and styrene, but in fact it is often a mixture of butadiene-containing graft copolymer and acrylonitrile-styrene copolymer, of which acrylonitrile accounts for 15%. -35%, butadiene accounts for 5%-30%, and styrene accounts for 40%-60%. In ABS resin, rubber particles are dispersed phase, dispersed in the continuous phase of SAN resin. Just because the continuous phase is SAN resin, the apparent performance of ABS resin is dominated by SAN resin, with certain hardness and gloss. The solubility parameter of ABS resin is between 10.6-11.0, which is similar to that of SAN resin (12.0-13.0), and the apparent polarity is relatively large. [0003] ABS high rubber powder is also polymerized from monomers acrylonitrile, butadi...
