Abstract
The invention discloses a metal-like folded plastic back-plate comprising a base plate, a metal-like layer and a film layer. The base plate is made of a reinforced PP (polypropylene) material, the metal-like layer is fixed on the upper surface of the base plate, and the film layer is fixed to the upper surface of the metal-like layer. The metal-like folded plastic back-plate and a refrigerator provided with the same have the advantages that manufacturing cost and weight of the back-plate can be reduced, appearance quality of the refrigerator can be improved remarkably and the like.
Description
Technical field
The present invention relates to a kind of refrigerator backboard, especially a kind of imitative metal appearance plastics bending postnotum for very flat back of the body refrigerator.
Background technology
At refrigerator industry, the postnotum that at present very flat back of the body refrigerator uses mainly contains two kinds of metal postnotum and plastics postnotums.Wherein metal postnotum mainly uses cold-rolled steel sheet spraying, PCM(Pre-coated metal, in advance coated metal plate) steel plate, Al-Zn coated steel, form by mould punching, need a large amount of steel, its manufacturing cost is higher; And adopting steel backboard, weight is larger, is unfavorable for the lightness of refrigerator.And plastics postnotum is mainly to use ABS(Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene copolymer) or HIPS(high impact polystyrene, high impact polystyrene) sheet material, process by heating bending technique.ABS and HIPS sheet material are plastic material, and cost is lower, and density is little, are convenient to the lightness of refrigerator, but ABS and HIPS sheet material postnotum percent defective are higher, and plastics appearance effects refrigerator presentation quality.
Summary of the invention
The present invention is the weak point existing in above-mentioned prior art for avoiding, and provides a kind of imitative metal appearance plastics bending postnotum, to reduce cost of manufacture and the weight of postnotum.
The present invention be technical solution problem by the following technical solutions.
Imitative metal appearance plastics bending postnotum, its design feature is to comprise substrate, the imitative metal level that strengthens PP material and make and the BOPP thin layer that prints the pattern of imitative metal appearance by ink screen printing technology thereon; Described imitative metal level is fixed on the upper surface of described substrate, and described thin layer is fixed on the upper surface of described imitative metal level.
On four limits of described postnotum, be provided with flange.
Angle between described flange and the substrate of described postnotum is 90 °.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Imitative metal appearance plastics bending postnotum of the present invention, be applicable to refrigerator back position, there is imitative metal appearance, postnotum, for very flat back of the body refrigerator back, has imitative metal (zinc-plated flower) outward appearance, and uses four sides bending structure, cost is low, technique assembling is easy, can significantly improve the presentation quality of refrigerator, further reduces the production material cost of refrigerator simultaneously.
1) the imitative metal postnotum of the present invention, by base material PP is carried out to modification, improves toughness and the impact strength of material, obviously reduces than the percent defective of former ABS or HIPS sheet material.
2) the imitative metal postnotum of the present invention uses ink and screen printing technique that the pattern with imitative metal (zinc-plated flower) outward appearance is imprinted on BOPP film, fuse by the PP of hot compress membrane technology and basic unit again, be that it has metal appearance, can promote refrigerator presentation quality.
Imitative metal appearance plastics bending postnotum of the present invention, have can reduce postnotum cost of manufacture and weight, can significantly improve the advantage such as presentation quality of refrigerator, be suitable for for very flat back of the body refrigerator back.
Accompanying drawing explanation

Fig. 2 is the stereogram of imitative metal appearance plastics bending postnotum of the present invention.
Fig. 3 is the use state diagram on refrigerator that is installed on of imitative metal appearance plastics bending postnotum of the present invention.
Mark in Fig. 1～Fig. 3: 1 substrate, 2 imitative metal levels, 3 thin layers, 4 postnotums, 5 flange, 6 refrigerators.
Below pass through the specific embodiment, and the invention will be further described by reference to the accompanying drawings.
The specific embodiment
Referring to Fig. 1～Fig. 3, imitative metal appearance plastics bending postnotum, it comprises substrate 1, the imitative metal level 2 that strengthens PP material and make and the BOPP thin layer 3 that prints the pattern of imitative metal appearance by ink screen printing technology thereon; Described imitative metal level 2 is fixed on the upper surface of described substrate 1, and described thin layer 3 is fixed on the upper surface of described imitative metal level 2.
On four limits of described postnotum 4, be provided with flange 5.
Angle between described flange 5 and the substrate 1 of described postnotum 4 is 90 °.
Thin layer adopts BOPP(Biaxially Oriented Polypropylene, bidirectional stretching polypropylene film) film.What the substrate of postnotum used is that modification strengthens PP(Polypropylene, polypropylene) material, there is approximate metal appearance effect.The imitative metal appearance on surface be use to be BOPP film print by ink screen printing technology the pattern of imitating metal appearance on film.The modification of substrate strengthens PP materials'use single screw extrusion machine extrudes, and carries out overlay film in mouth mould position, by heat fusion techniques, film and basic unit is closely linked.The tow sides of postnotum must carry out patterned roll embossing processing, and decorative pattern has two kinds of dermatoglyph and grid lines.The dual-side of postnotum and upper below by after heating bending processing, shape flange in 90 °.
Postnotum of the present invention comprises three layers: substrate, imitative metal level and thin layer.By PP is carried out to modification as base material, use ink screen printing technology that the pattern of imitative metal appearance is imprinted on to BOPP film, then BOPP film and PP sheet material are fused by hot compress membrane technology, produce imitative metal postnotum.MODIFIED PP base material can reduce postnotum percent defective, and metal appearance can promote refrigerator presentation quality, and imitative metal postnotum can reduce production material cost simultaneously.
PP material modification technology application: mainly improve toughness of material, improve the impact strength of material, reduce formulation cost; Imitative metal appearance decoration technique research: use ink and screen printing technique that the pattern with imitative metal (zinc-plated flower) outward appearance is imprinted on BOPP film; Spend (interior embossing) and hot film coating techniques by extruder three roll-ins: make the imitative decorating film of metal appearance and the PP of basic unit realize fusion, auxiliary multiple tracks corona operation simultaneously, the caking property of raising sheet material and PU foam.
As shown in Figure 1, use modification to strengthen the extrusion molding of PP material and produce substrate 1, tow sides carry out patterned roll embossing processing simultaneously, and decorative pattern has dermatoglyph and grid line.In addition, the face contacting with expanding foam solution will carry out sided corona treatment, to strengthen adhesion; Use ink and screen printing technique that the imitative metal level 2 of the pattern with imitative metal (zinc-plated flower) outward appearance is imprinted on BOPP film 3; By hot film coating technique, the imitative decorating film of metal appearance and the PP of basic unit are realized to fusion again.After heating bending is processed, shape flange in 90 °, is made into required postnotum (Fig. 2).The position that postnotum assembles in refrigerator 6 as shown in Figure 3.
Above-mentioned these examples are only not used in and limit the scope of the invention for the present invention is described, are reading after the present invention, and those skilled in the art all falls into the application's appended claims limited range to the modification of the various equivalent form of values of the present invention.
