Background technology
Current refrigerator using sheet material level HIPS or ABS, passes through plate squeezing, plastics sucking moulding inner container of icebox mostly.However, ABS because
Its cost is higher, can not meet the reasons such as food security, is gradually substituted by sheet material level HIPS.HIPS is in order to reach height for sheet material level
The characteristics of toughness, the rubber of big particle diameter is added in the course of the polymerization process, thus its surface is matte effect, outward appearance, which is difficult to meet, to be wanted
Ask.Generally there is the HIPS of bloom effect, but bloom using multi-layer co-extruded method in laminating one layer of dumb light layer surface at present
HIPS surface chemical resistance is poor, easily cracks.When inner container of icebox is contacted with polyurethane foamed thermal-insulating layer, gather
Foaming agent in urethane insulating foam layer can produce corrosiveness to HIPS materials inner bag, easily form crackle.Thus, existing process
In by multi-layer co-extruded mode, in the laminating one layer of PE/PS alloy-layer in surface contacted with polyurethane foamed thermal-insulating layer, to carry
High inner container of icebox inner surface corrosion resistance.
To sum up, current refrigerator inner bag needs to use to reach the effect of the anti-foaming agent corrosion of outer surface high glaze, inner surface
Bloom HIPS, dumb light HIPS (high tenacity HIPS) and PE/PS alloys it is three-layer co-extruded go out manufacture craft.But the technical process is multiple
Miscellaneous, each thickness degree is difficult to control to, and production cost is higher.Simultaneously as HIPS belongs to non-polar material, polyurethane foamed thermal-insulating layer
Belong to polar material, the cementitiousness of the two need to be ensured using surface corona technique at present, producting process difficulty is added again.
