Problems solved by technology

[0002] Plastic has the advantages of low cost, easy processing, and collision resistance, but generally its finished product is not rich enough in appearance, and the feel is not liked by most people, so it is not suitable for contact and use in daily life
The appearance of plastic with partial frosted effect is more cool, but the surface of plastic material with partial frosted effect prepared by traditional technology is often difficult to be stably combined with other functional coatings to improve user experience, so it is often difficult for partially frosted plastic to have an ideal appearance.

preparation example Construction

[0052] On the other hand, the present invention provides the preparation method of above-mentioned abrasive material, and this preparation method comprises the following steps:

[0053] Step S1, providing a substrate, the surface of the substrate is a plastic surface;

[0054]The plastic base material can be selected from commonly used portable electronic devices such as casing materials of mobile phones, or materials of protective cases thereof. Further, some hard plastic materials can be selected, for example, the plastic material is but not limited to at least one of polycarbonate plastic, polymethyl methacrylate and ABS plastic.

[0055] The plastic substrate can be pre-processed into the shape of the prepared device according to actual needs, or it can be a finished unprocessed plastic sheet. The plastic base material preprocessed into a device shape can be directly prepared through the preparation method provided by the invention to obtain the desired frosted plastic pr...

[0095] Plastic cover with frosted effect in local areas

[0096] (1) Hardening treatment: Prepare the pre-formed and cleaned plastic cover plate, pour a layer of high-hard fluorine-free light-curable coating on the surface of the plastic cover plate, and apply ultraviolet light for 5 minutes to make it completely cured, so that A hardened layer is formed on its surface.

[0097](2) Forming a partial protective layer: by screen printing, a layer of peelable glue is printed on the area of ​​the plastic cover plate that forms a hardened layer on the surface as a smooth surface to form a partial protective layer. The thickness is 7 μm.

[0098] (3) Matte treatment: use the method of sandblasting to perform frosting treatment on the plastic cover plate with a partial protective layer on the surface, so that the surface has a frosted texture as a whole.

[0099] (4) Back protection: Use a scraper to peel off the peelable glue on the surface of the frosted plastic back cover to exp...

[0102] Plastic cover with frosted effect in local areas

[0103] (1) Hardening treatment: Prepare the preformed and cleaned plastic cover plate, spray a layer of high-hard light-curing paint on the surface of the plastic cover plate and apply ultraviolet light for 3 minutes to make it completely cured, so that the surface Form a hardened layer.

[0104] (2) Forming a partial protective layer: by screen printing, a layer of peelable glue is printed on the area of ​​the plastic cover plate that forms a hardened layer on the surface as a smooth surface to form a partial protective layer. The thickness is 9 μm.

[0105] (3) Frosted treatment: use laser etching method to perform frosted treatment on the plastic cover plate with partial protective layer formed on the surface, so that the surface has a frosted texture as a whole.

[0106] (4) Back protection: Use a scraper to peel off the peelable glue on the surface of the frosted plastic back cover to expose the original plastic ...

Abstract

The invention relates to the technical field of plastics, in particular to a partially frosted plastic material. The partially frosted material disclosed by the present invention comprises a base material and a hardened layer arranged on the base material, the surface of the hardened layer has a frosted area and a smooth area, the surface of the base material is a plastic surface, and the hardened layer is set on the plastic surface. The above materials are frosted in some areas and bright in some areas, and the appearance is cool. Moreover, the partially frosted material can be further firmly combined with the functional coating, so that it has better grip performance.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a partially frosted material and a preparation method, a partially frosted shell, and electronic equipment. Background technique [0002] Plastic has the advantages of low cost, easy processing, and impact resistance, but generally its finished product is not rich enough in appearance, and most people don't like the hand feeling, so it is not suitable for contact and use in daily life. The appearance of plastic with partial frosted effect is more cool, but the surface of plastic material with partial frosted effect prepared by traditional technology is often difficult to be stably combined with other functional coatings to improve user experience, so it is often difficult for partially frosted plastic to have an ideal appearance. Use performance. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to...
