Problems solved by technology

[0003] At present, the refrigerator box liner, door liner and freezer door liner on the market are mainly traditional HIPS (high impact polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer). Liner cost is low and easy to process, but the gloss is low and the texture is poor. The traditional ABS liner has high gloss and high-end texture, and has better chemical resistance, but the cost is higher

preparation example Construction

[0048] refer to figure 2 , figure 2 Show the flowchart of the preparation method of refrigerator liner material of the present invention, the preparation method of this refrigerator liner material is as follows, comprises the following steps:

[0049]S1. Weigh 5-15 parts of the surface ABS material according to the mass ratio and add it to the material tank 1;

[0050] S2. Weigh 85-95 bottom layer alloy materials according to the mass ratio and add them to the barrel 2;

[0051] S3. The board is extruded by double-layer extrusion technology. The extrusion process parameters of the main machine are: 170-180°C in the first zone, 200-210°C in the second zone, 210-220°C in the third zone, and 220-230°C in the fourth zone. The five-zone temperature is 220-230°C, the head temperature is 220-230°C, the host speed is 300-450 rpm; the auxiliary machine extrusion process parameters are: the first zone 175-185°C, the second zone temperature 205-215°C, the third zone The temperature ...

Embodiment 1

[0055] The high-gloss low-cost refrigerator liner material of this embodiment is composed of a high-gloss ABS material on the surface and an ABS alloy material on the bottom layer. Wherein, the parts by weight of each component are 10% for the high-gloss ABS layer on the surface, and 90% for the ABS alloy layer at the bottom.

[0056] The ABS material of the surface layer is ordinary extruded board grade ABS, and its physical and chemical properties are shown in Table 1.

[0057] Table 1 surface material properties

[0058]

[0059] The matrix resin of the bottom ABS alloy layer is an alloy material of ABS and PP materials, wherein ABS resin is 110 parts, and PP resin includes homopolymerized PP and copolymerized PP, wherein the ratio of homopolymerized PP and copolymerized PP is 5:1, A total of 35 parts, the compatibilizer is the first compatibilizer and the second compatibilizer compound, wherein the parts by weight of the first compatibilizer are 1.5 parts, and the part...

Abstract

The invention provides a refrigerator, a refrigerator liner, a refrigerator liner material and a preparation method of the refrigerator liner material. A double-layer co-extrusion technology is adopted for the refrigerator liner material, a surface layer is made of a common ABS material, a bottom layer is made of a modified ABS alloy material, and the modified ABS alloy material of the bottom layer is an ABS / PP alloy material. The liner material has good compatibility and chemical resistance for a pure cyclopentane system, a cyclopentane and 245fa (cyclopentane and 1,1,1,3,3-pentafluoropropane) foaming system, a cyclopentane and LBA (a new generation of hard foam foaming agent) foaming system and a pure LBA (a new generation of hard foam foaming agent) foaming system. Compared with a traditional liner preparation process, the refrigerator liner prepared through the refrigerator liner material is high in glossiness, good in appearance, high in texture grade, high in machinability, highin machining process and equipment universality and lower in cost compared with a traditional ABS liner.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator, a refrigerator liner, a material for the refrigerator liner and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, consumers put forward higher demands on the appearance, energy consumption and texture of refrigerators. For example, multi-door large-capacity refrigerators such as side-by-side, cross-door, and French-style four-door refrigerators, and refrigerators with stylish appearances such as frosted brushed glass doors and Ruiya black brushed steel doors are more and more popular among consumers. [0003] At present, the refrigerator box liner, door liner and freezer door liner on the market are mainly traditional HIPS (high impact polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer). The inner liner is low in cost and easy to process, but the glo...
