[0027] The preparation method of high-performance HIPS resin includes the following steps: according to the weight parts of the formula components in Table 1 and Table 2, the raw materials are added to a high-speed mixer and fully mixed, and then placed in a screw machine, and extruded at a temperature of 220 ° C. And 500 rev / min screw speed for melt extrusion, cooling and granulation to obtain the product.

[0028] Wherein, the raw materials of Table 1 and Table 2 are as follows:

[0029] HIPS1: Taihua HP8250, melt index 5.5g / 10min, notched impact strength 11kJ / m 2 ;

[0030] HIPS2: Taihua HP825T, melt index 11g / 10min, notched impact strength 9kJ / m 2 ;

[0031] SPS: purchased from Idemitsu, Japan, with a weight average molecular weight of 150,000;

[0032] Toughening agent 1: Rizhisheng MAH-g-POE, MAH content 0.6-0.8%;

[0033] Toughening agent 2: Rizhisheng MAH-g-SBS, MAH content 1.5%;

[0034] Toughening agent 3: Rizhisheng MAH-g-SEBS, MAH content 0.5-0.8%;

Abstract

The high-performance HIPS resin composition is prepared from the following components in parts by weight: 70 to 87 parts of HIPS resin, 10 to 20 parts of SPS resin, 3 to 10 parts of a toughening agent, 0.5 to 1 part of a compatilizer and 0.1 to 1 part of an antioxidant. The characteristics of high heat resistance, high strength and high chemical resistance of the crystalline SPS are utilized, and the crystalline SPS is compounded with the HIPS, so that the high-performance HIPS resin composition with excellent mechanical property, heat resistance, chemical resistance and weather resistance is obtained; the obtained high-performance HIPS resin composition is easy to prepare and low in cost, and the performance of the high-performance HIPS resin composition is superior to that of ABS.

Description

technical field [0001] The invention relates to the technical field of resin compositions, in particular to a high-performance HIPS resin composition and a preparation method thereof. Background technique [0002] HIPS has excellent toughness, rigidity and fluidity, as well as its low cost, and is widely used in large and small home appliance shells. Compared with ABS, HIPS has lower price, lower surface polarity and better matte performance; and its heat resistance, chemical resistance and mechanical properties are not as good as ABS. Under the pattern of cost competition, HIPS has become an industry trend to replace ABS. Improving the heat resistance, chemical resistance and mechanical properties of HIPS can make it replace ABS in more occasions. [0003] HIPS and PPO are two very compatible materials. PPO can significantly improve the heat resistance, strength and toughness of HIPS, making its performance consistent with or better than ABS. However, the addition of PPO ...
