Embodiment 1

[0029] The board is made of polyethylene / polystyrene alloy raw materials (8 parts by weight of high-density polyethylene / 80 parts by weight of Chevron HIPS-D6007), and 12 parts by weight of additives are added. Among them, based on the total weight of additives, the rubber elastomer The content is 5 parts by weight, the content of the compatibilizer is 7 parts by weight, processed into a single-layer plate through co-extrusion process, and thermoformed to obtain the plate A. Place the board A in a foam box with a single foaming agent, cyclopentane, and place it at room temperature for 12 hours, then put it in a high and low temperature test box for 4 cycles, and observe the state of the lining after the test. There are no cracks, dark cracks and cracks in the tank liner.

Embodiment 2

[0031] The board is made of polyethylene / polystyrene alloy raw material (75 parts by weight of low density polyethylene / 10 parts by weight of Styron HIPS-1175), and 15 parts by weight of additives are added, wherein, based on the total weight of additives, the content of rubber elastomer is 30 parts by weight, and the content of the compatibilizer is 13 parts by weight, processed into a single-layer board through a co-extrusion process, and thermoformed to obtain a board B. Place the board B in a foaming box with multi-element foaming agent cyclopentane / HFC-245fa as the foaming material, place it at room temperature for 12 hours, then put it into a high and low temperature test box for 4 cycles, and observe the state of the lining after the test. There are no cracks, dark cracks and cracks in the tank liner.

Embodiment 3

[0033] The board is made of polyethylene / polystyrene alloy raw material (30 parts by weight linear low density polyethylene / 55 parts by weight Yamba HIPS-2710), and 14 parts by weight of additives are added, wherein, based on the total weight of the additives, the rubber elastomer The content is 18 parts by weight, the content of the compatibilizer is 10 parts by weight, processed into a single-layer board through co-extrusion process, and thermoformed to obtain the board C. Place plate C in a foaming box with multi-component blowing agent cyclopentane / HFC-245fa / HFC-134a as foaming material, place it at room temperature for 12 hours, then put it in a high and low temperature test box for 4 cycles, observe the test Lined condition. There are no cracks, dark cracks and cracks in the tank liner.

Abstract

The invention provides an alloy material, a plate for an inner liner of a refrigeration device, an inner container for the inner liner of the refrigeration device and the refrigeration device, and the refrigeration device. The alloy material is a polyethylene / polystyrene alloy or a polypropylene / polystyrene alloy. According to the alloy material of the embodiment of the invention, the alloy material simultaneously has great toughness on the basis of keeping relatively high strength; the alloy material further has great capability of resistance to corrosion of a single foaming agent, a polynary mixed foaming agent, edible oil and the like; in addition, as the toughness and strength of the alloy material can achieve great balance by formula adjustment, the thickness of the plate can be thinned by 10%-50% on the basis of keeping the technical standard of the existing plate for the refrigeration device, and then the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of home appliances, and in particular, relates to an alloy material used for the inner lining of a refrigeration equipment, a plate used for the inner lining of the refrigeration equipment and a preparation method thereof, an inner lining for the refrigeration equipment and a refrigeration equipment having the same. Background technique [0002] The lining materials of refrigeration equipment in the prior art mainly include: 1. HIPS composite board, the surface layer is high-gloss / matte HIPS, and the bottom layer is special HIPS for extrusion-grade refrigerators; 2. ABS single-layer board, using board-level ABS for dyeing The material is extruded in a single layer through a sheet extruder. But HIPS composite sheet and ABS single-layer sheet are only suitable for cyclopentane foaming system. With the improvement of energy consumption requirements and the reduction of production costs, the application of multi-componen...
