Abstract

A protecting film for the metallic plate with ethylene-base covering surface which is used for domestic electric appliances is prepared from transparent low-density polyethylene which has 250-300% of elongation percentage, 1.2-1.7 kgf/sq.mm of extension strength, 100-150 g/25 mm of adhesion and 60-100 microns of thickness.

Description

Protection film for ethelene-based coated metal plate
Technical field
The invention relates to the metallic plate diaphragm of household appliances, particularly be a kind of protection film for ethelene-based coated metal plate.
Background technology
Usually utilizing vinyl clad can metallic plate to constitute the shell of household appliances such as refrigerator and air-conditioning, for the facility that illustrates, is that example describes with the door of refrigerator.
Inside at door of refrigerator is provided with thermal insulation layer, therefore, forms the chamber door profile in order to protect thermal insulation layer, and the chamber door shell utilizes the metallic plate manufacturing.At this moment, the surface of metallic plate shell by spary, forms the color of regulation.
But, use vinyl clad can metallic plate recently, make door of refrigerator possess the texture of multiple material.As shown in Figure 1, vinyl clad can metallic plate 1 is made of the mother metal 3 of metal material and the PVC layer 5 that forms on mother metal 3 surfaces and the pet layer 7 that is attached on the PVC layer 5.Here, it is 0 very smooth surface that pet layer 7 surfaces have roughness, can print various decorative patterns and shades of colour in the above.
And, when adopting vinyl clad can metallic plate 1 to make door of refrigerator, pass through processes such as panel beating, and in these processes,, protective film 10 be attached to pet layer 7 surfaces in order to make vinyl clad can metallic plate 1 surface injury-free.And, in processing door of refrigerator and when transportation, in order to prevent vinyl clad can metallic plate 1 surface damage, above diaphragm 10 continues to be attached to.This protective film 10 mainly adopts transparent high-density polyethylene material.
But, when making the pet layer 7 of vinyl clad can metallic plate 1, make it possess certain surface roughness, recently to possess the texture of metal material.
As mentioned above; possess the surface roughness of regulation and the pet layer 7 of special metal material sense; because of having higher relatively precision; therefore; adopt the diaphragm 10 of traditional high density polyethylene (HDPE) material; can't intactly protect pet layer 7 in operation, the part of vinyl clad can be in operation process such as panel beating, damage to some extent.
As mentioned above, possess the vinyl clad can metallic plate 1 of the bigger pet layer of surface roughness 7, when adopting the protective film 10 of high density polyethylene (HDPE) material, the easy phenomenon that comes off.
Summary of the invention
In order to solve above problem, the objective of the invention is when the vinyl clad can metallic plate of processing metal texture, the protective film of effective protection vinyl clad can part is provided.
In order to achieve the above object; the present invention implements by following scheme: vinyl clad can metallic plate constitutes by the mother metal of metal material with at PVC layer that forms on the mother metal surface and the pet layer that is attached on the PVC layer; protective film of the present invention is formed on the mother metal of metal material; keeping the mean roughness of center line is 0.3-1.0; and have on the pet layer of metal-like; protective film is to adopt tranparency and low density polyethylene material; be attached on the pet layer; adhesive force is 100-150g/25mm, and protective film thickness is 60-100 μ m.
Adopt the protection film for ethelene-based coated metal plate of using of the present invention's design, make relative accuracy higher, and have the processing of vinyl clad can metallic plate of metal-like more safe and reliable.
In sum; the protective film of the present invention's design; in engineering, protect the relative accuracy height and have certain surface roughness; and the pet layer of the vinyl clad can metallic plate of special metal texture; in processing or transportation; protective film protection pet layer helps to make profile door of refrigerator more attractive in appearance.
Description of drawings
Fig. 1 is the structure oblique view of the protection film for ethelene-based coated metal plate of conventional art.
Fig. 2 is a protection film for ethelene-based coated metal plate structure oblique view of the present invention.
Among the figure
1 vinyl clad can metallic plate, 3 mother metals
5 PVC layers, 7 pet layer
10 protective films
The specific embodiment
The present invention will be described in detail below in conjunction with the drawings and specific embodiments, as shown in Figure 2, has the surface of the vinyl clad can metallic plate 1 of PVC layer 5 and pet layer 7 on the mother metal 3 of metal material, is covered with protective film 10.
The relative hardness height of the pet layer 7 of vinyl clad can metallic plate 1, its thickness are about 0.13 μ m.And it is 0.3-1.0 that its surface roughness is got center line average roughness.Such pet layer 7 just can possess the texture of metal material.
In order to have aforesaid high rigidity in processing, and when having the vinyl clad can metallic plate 1 of PET of regulation roughness, protect described pet layer, and use protective film.
Protective film 10 adopts the low density polyethylene (LDPE) material, and its density approximately is 0.910-0.925.And because of the hardness height of pet layer 7, so damage in order to prevent in the process of chamber door, preferably in the 60-100 mu m range, the best is 80 μ m to its thickness.
The percentage elongation of protective film maintains in the scope of 250-300%, and tensile strength preferably maintains 1.2-1.7kgf/mm 2Scope in.
Below, the effect of above-mentioned protection film for ethelene-based coated metal plate of the present invention is described.
Protective film 10 of the present invention possesses physics value as above.For example, when making door of refrigerator, be attached to the surface of the preceding vinyl clad can metallic plate 1 of chamber door, till the manufacturing of finishing chamber door, the pet layer on protection vinyl clad can metallic plate 1 surface.
Particularly for the high rigidity of bringing pet layer 7 and the texture of metal material, the present invention is applied to finish after the color and Surface Treatment Engineering of regulation, and by such surface treatment, vinyl clad can metallic plate 1 has the texture of special metal.
When utilizing vinyl clad can metallic plate 1 to make door of refrigerator, adopt protective film 10 as above, prevent in the processing or transportation of panel beating etc., bad at vinyl clad can metal sheet surface generation cut or panel beating.
And it is higher relatively that protective film 10 attaches to the adherence force of pet layer 1, so after finishing the making engineering of chamber door, when separating with vinyl clad can metallic plate 1, protective film 10 is not in order to be torn and complete getting rid of.
