Description

Frosted 3D special-effect VCM composite steel plate

Technical Field

The utility model belongs to the technical field of the composite decoration panel, especially, relate to a dull polish 3D special effect VCM clad steel sheet.

Background

The VCM product front that uses in the household electrical appliances trade all is smooth, does not do any processing, because the front is the appearance contact surface, soft scratch and fracture problem can appear easily in daily use, and the front receives the destruction back, and the whole weatherability of product will descend, so can lead to product life to shorten seriously. Because the front surface glossiness of PET is very high, can reach 300 degrees, and the surface is also very clean simultaneously, and after this surface state retreats dull polish material, dull polish material and PET direct laminating performance are very poor, receive high temperature, and the granule drops easily, and the performance of product can't satisfy the requirement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dull polish 3D special effect VCM clad steel sheet forms the corona layer through adopting corona technology to handle on the PET layer, forms the dull polish layer again in corona layer coating, has solved the very poor problem of current dull polish material and the direct laminating performance of PET.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a dull polish 3D special effect VCM clad steel sheet, including the substrate layer, the two sides of substrate layer form first chromium-free passivation layer and second chromium-free passivation layer respectively through passivation treatment; one side coating of second chromium-free passivation layer has epoxy back paint layer, be equipped with gum layer, adhesive layer, imitative wire drawing layer, 3D printing layer, PET layer, corona layer and dull polish 3D layer in proper order on the one side of first chromium-free passivation layer.

Further, the first and second chromium-free passivation layers have a thickness of 2-10 μm.

A preparation method of a frosted 3D special-effect VCM composite steel plate comprises the following steps:

step 1, respectively forming a first chromium-free passivation layer and a second chromium-free passivation layer on two sides of a base material layer through passivation treatment;

step 2, coating an epoxy back paint layer on one surface of the second chromium-free passivation layer;

step 3, sequentially forming a back glue layer, an adhesive layer, a wiredrawing-simulated layer, a 3D printing layer and a PET layer on the first chromium-free passivation layer;

and 4, forming a corona layer on the PET layer by adopting corona treatment, and finally forming a frosting layer on the corona layer by coating through a micro-gravure roll, a reticulate pattern roll or a spray painting mode.

The utility model discloses following beneficial effect has:

the corona layer is formed on the PET layer by adopting corona treatment, and then the frosted layer is formed by coating the corona layer, so that the problem that the direct laminating performance of the existing frosted material and PET is poor is solved; the problem that the abrasive particles are not peeled off after being baked for 24 hours at the temperature of 240 ℃ by using a strong adhesive tape can be solved.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
