Problems solved by technology

[0003] This kind of ABS special dyeing material usually needs to be purchased from different manufacturers due to the large amount of use, so there are problems of color difference and performance difference between different grades of ABS special dyeing materials provided by different suppliers
In addition, different ABS dyeing materials cannot be mixed due to compatibility issues, which causes inconvenience to production management
Moreover, due to its high performance requirements, only a few companies can produce this kind of ABS special material for dyeing. At present, it basically relies on imports, so the purchase cycle is long and the price is high.

Embodiment 1

[0027] Embodiment 1: double-layer ABS layered composite board (total thickness: 1.8mm) and door liner

[0028] The raw material of the surface layer is dyed ABS-775T produced by KUMHO PETROCHEMICAL.

[0029] The raw material of the anti-corrosion layer is matt ABS-3513 produced by Sinopec.

[0030] The coextrusion head was adjusted so that the thickness of the surface layer was 0.1 mm, and the thickness of the corrosion-resistant layer was 1.70 mm.

[0031] Dry at 80 degrees centigrade for 4 hours, and then extrude at 220 degrees centigrade through a co-extruder to obtain a double-layer ABS laminated composite board.

[0032] The obtained ABS laminated composite sheet is made into a door lining of a refrigeration device through vacuum thermoforming at 145 degrees Celsius. It can be used in refrigeration equipment using cyclopentane foaming.

Embodiment 2

Abstract

The invention discloses an acrylonitrile butadiene styrene (ABS) laminated composite plate and a refrigeration equipment liner. The laminated composite plate comprises a surface layer consisting of high gloss ABS, and a corrosion resistant layer consisting of foamer corrosion resistant ABS. According to the ABS laminated composite plate, the surface layer consists of the high gloss ABS, so the ABS laminated composite plate has good glossiness and is easy to clean. Meanwhile, because the corrosion resistant layer consists of the foamer corrosion resistant ABS, so the ABS laminated composite plate is foamer corrosion resistant. In addition, the general high gloss ABS and foamer corrosion resistant ABS are adopted to replace ABS dyeing special materials, so the cost is greatly reduced. Moreover, the requirement on the performance of a single material is reduced, so more material choices are provided, raw materials are convenient to purchase and the localization of the raw materials is realized.

Description

technical field [0001] The invention relates to the field of refrigeration equipment manufacturing, in particular to an ABS layered composite board and a refrigeration equipment inner container prepared therefrom. Background technique [0002] ABS boards used for refrigerators and freezer liners in the prior art are usually formed by single-layer extruding of board-level ABS dyeing materials through extruders. This kind of board needs to have good anti-foaming agent corrosion, and in addition, it is required to have high gloss from the perspective of appearance and easy cleaning. [0003] This kind of ABS special dyeing material usually needs to be purchased from different manufacturers due to its large usage. Therefore, there are problems of color difference and performance difference among different grades of ABS special dyeing materials provided by different suppliers. In addition, different ABS dyeing materials cannot be mixed due to compatibility issues, which causes i...
