Embodiment 1

[0044] The preparation method in embodiment one and comparative example one, comprises the following steps:

[0045] (1) Weigh and take various raw materials according to weight percentage;

[0046] (2) Mix HIPS, polyethylene resin, toughening compatibilizer, raw gypsum powder, antioxidant, reactive castor oil, lubricant, etc. in a high-speed mixer for 3-5 minutes;

[0047] (3) Place the above-mentioned mixed materials in the main feeding port of a twin-screw extruder with a length-to-diameter ratio of 36:1, melt and extrude to granulate, and the extruded materials are cooled, air-dried, pelletized, and dried. Corrosion of HIPS composites with low-odor anti-foaming agents for refrigerators.

[0048] The temperature setting range of the twin-screw extruder is 65-185°C, the screw speed is 200-500rpm, the vacuum at the end of the extruder is -0.08-0.09MPa, and the temperature of each zone of the twin-screw extruder is:

[0049] Zone 1 temperature: 65°C, Zone 2 temperature: 70°C...

Abstract

The invention discloses a low smell corrosion-resistant HIPS composite material for a refrigerator and a preparation method thereof. The composite material is prepared from the following components inparts by weight: 100 parts of HIPS, 10-40 parts of polyethylene resin, 5-15 parts of a toughening compatilizer, 10-20 parts of gypsum powder, 0.1-0.5 part of a main antioxidant, 0.1-0.5 part of an auxiliary antioxidant, 0.1-0.5 part of a lubricant and 1-5 parts of reactive castor oil. The preparation method comprises the following steps: vaporizing water in the raw material gypsum powder in a fusing processing process; vacuumizing small molecular substances capable of generating smell in the HIPS and polyethylene to take away the materials; and combining smell substances in an active functional group chelating material of the reactive castor oil to form a stable novel compound so as to prepare the low smell foaming agent corrosion-resistant HIPS high performance composite material, so that the content of VOCs is reduced effectively, and the demand of the composite material of the refrigerator on low smell is met.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a low-odor and anti-corrosion HIPS composite material for refrigerators and a preparation method thereof. Background technique [0002] Refrigerators are one of the most frequently used home appliances in our daily life. The existing refrigerator door end cover materials are mainly ABS materials, but ABS materials are only suitable for cyclopentane foaming systems. In the multi-component foaming system, the ABS end cover Cracking occurs in batches. The patent CN105504638A solves this problem well through the formula design of the alloy, but the common preparation method usually has some odor due to the small molecules such as residual monomers. As people's requirements for home appliance materials are getting higher and higher, the requirements for indoor air quality are also increasing. At present, most of the plastic materials of household appliances contain...
