Embodiment 1

[0029] Embodiment 1# The toughening functional masterbatch of a kind of PS class material is characterized in that: the parts by weight of each component of its composition raw material is:

[0030] Embodiment 1#:

[0031] 22 parts of SBS resin

[0032] 20 parts plasticizer

[0033] 30 parts polypropylene

[0034] Antioxidant 0.06 parts

[0035] Filling 12 parts

[0036] Pigment 0 parts

[0037] Concrete preparation method comprises the following steps:

[0038] Step 1: Add SBS resin to the high mixer, stir, then slowly spray plasticizer into SBS resin, control the temperature at 65°C, so that the plasticizer is continuously absorbed into the SBS resin;

[0039] Step 2: Add the following components together into the high mixer and stir for 3 minutes, then take out of the pot;

[0040] Step 3: Add the above-mentioned mixed materials into a twin-screw extruder for mixing, granulation, and packaging. The granulation temperature is 150°C, and the granulation adopts the unde...

Embodiment 2

Abstract

The invention discloses toughening functional masterbatch of PS materials. The toughening functional masterbatch is characterized by being prepared from, by weight, 20-60 parts of SBS resin, 5-40 parts of plasticizers, 5-50 parts of polypropylene, 0.002-1 part of antioxidants, 5-50 parts of packing and 0-25 parts of pigment. The toughening functional masterbatch of the PS materials has the significant chemical corrosion resistance, the toughening function, the dyeing and color mixing properties and the good covering power, is stable in color and good in weather resistance and can be mixed according to the customer requirements.

Description

technical field [0001] The invention relates to the field of plastics and modified plastics, in particular to a toughening functional master batch of PS material and a production process thereof. Background technique [0002] With the continuous development and competition of the home appliance market, the use of bulk materials requires continuous cost optimization, such as replacing ABS with PS materials, and replacing PS or ABS with PP. However, the demand for refrigerators mainly comes from replacements and product upgrades. Energy saving, environmental protection, and high-end appearance are the major trends in the development of the refrigerator market. Refrigerators with large capacity and multiple doors are one of the products favored by customers, and large-capacity refrigerators have great influence on products. Various technical indicators put forward higher requirements. The same goes for the air conditioner. [0003] When conventional HIPS is used instead of AB...
