Problems solved by technology

[0002] In the prior art, natural color HIPS is usually used for the surface layer of the liner of refrigeration equipment. This original HIPS material has poor weather resistance, is easy to age, and will turn yellow and crack after a period of use.
In order to improve the gloss, facilitate cleaning and make the appearance more exquisite, a layer of high-gloss HIPS is usually coated on the surface of the HIPS liner, but the high-gloss HIPS has poor ESCR resistance, and the matte HIPS has too low gloss and is difficult to clean, etc.
[0003] Therefore, present refrigeration equipment liner and preparation method thereof still need to be improved

Embodiment 1

[0040] Example 1: White enhanced weather-resistant bright masterbatch

[0041] Weigh 35 parts by weight of HIPS-1175, 35 parts by weight of SBS1301, 15 parts by weight of KN4010 and 15 parts by weight of titanium dioxide, add SBS1301 and KN4010 into the mixer, mix well, then add HIPS-1175 and titanium dioxide Mix evenly, and use a twin-screw co-rotating extruder to granulate to obtain a white bright masterbatch with enhanced weather resistance.

Embodiment 2

[0042] Example 2: White enhanced weather-resistant high-brightness masterbatch

[0043] Weigh 30 parts by weight of HIPS-888G, 38 parts by weight of Kraton1101, 16 parts by weight of KG16c, 11 parts by weight of titanium dioxide and 5 parts by weight of brightener, add Kraton1101 and KN4010 into the mixer, mix well, and then add HIPS- 888G, titanium dioxide and brightener are added and mixed, extruded through a twin-screw co-rotating extruder, and pelletized to obtain a white masterbatch with enhanced weather resistance and high brightness, dried and packaged.

Embodiment 3

[0044] Example 3: White enhanced weather-resistant high-brightness masterbatch with anti-photooxidative aging function

[0045] Add HIPS-1180, SBS4303, KN4010, titanium dioxide, brightener and anti-photooxidative aging agent according to the ratio of 30:30:15:17:7:1 (mass ratio) into the mixer and mix them. Extruder granulation to obtain white enhanced weather-resistant high-gloss masterbatch with strong anti-light and oxygen aging.

Abstract

The invention discloses a master batch composition, a compound board and a preparation method of the compound board, and a refrigeration plant. The master batch composition comprises 20-40 parts by weight of a matrix resin which is selected from HIPS (High Impact Polystyrene), 30-50 parts by weight of a flexibilizer which is selected from at least one of SBS (Styrene-Butadiene-Styrene), butadiene styrene rubber, naphthenic oil, PE-g-PS (Polythene-g-Polystyrene), POE-g-PS (Polyolefin-g-Polystyrene), EPDM-g-PS (Ethylene-Propylene-Diene Monomer-g-Polystyrene), 3-20 parts by weight of pigment, 0-10 parts by weight of a brightener, 0-3 parts by weight of an anti-light and oxygen ageing agent and 5-20 parts by weight of an antistatic agent. Thus, the master batch composition can effectively prepare a liner and can further increase the strength of the surface of the liner, increase the anti-cracking ability and particularly the resistance to chemical corrosions such as oils, cleaning agents and the like, increase the weather resistance and the surface gloss and increase the antistatic and dirt-proof functions, so that the liner is easier to clean.

Description

technical field [0001] The invention relates to a masterbatch composition, a composite plate, a preparation method thereof, and a refrigeration device. Background technique [0002] In the prior art, natural color HIPS is usually used for the surface layer of the liner of the refrigeration equipment. This original HIPS material has poor weather resistance, is easy to age, and will turn yellow and crack after a period of use. In order to improve the gloss, facilitate cleaning and make the appearance more exquisite, a layer of high-gloss HIPS is usually coated on the surface of the HIPS liner, but the high-gloss HIPS has poor ESCR resistance, and the matte HIPS has too low gloss and is difficult to clean. [0003] Therefore, the current refrigerator liner and its preparation method still need to be improved. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. [0005] For this reason, an o...
