Description

Ceramic plastic composite product and manufacturing method thereof

The invention relates to a ceramic plastic composite product and a preparation method thereof.

Both plastics and ceramics are important industrial materials. For functional or decorative purposes, it is sometimes necessary to combine ceramics and plastics. Although this can be done by various methods, such as mechanical fastening, the process of manufacturing a composite of ceramics and plastics by means of mechanical fastening is complicated, and, during the fastening process, The ceramic piece may be broken due to excessive force. In addition, the structure of the composite product itself is also relatively complicated. When the composite product is used for a decorative part, such as an electronic device casing, it is difficult to form a diversified combination between plastic and ceramic, and it is difficult to obtain a better decorative effect.

In view of this, the present invention provides a ceramic plastic composite product which is versatile and has a good decorative effect.

In addition, a method for manufacturing the above ceramic plastic composite product is provided.

A ceramic plastic composite product comprising a ceramic substrate and at least one insert disposed on the ceramic substrate, wherein the ceramic substrate is provided with an embedded portion, the insert is filled in the embedded portion and the ceramic The base body is integrally formed of plastic, and the embedded portion is composed of at least one through hole formed in the ceramic base body, and the through hole has two openings At least one large diameter portion is formed between the openings, and the embedded portion is formed by at least one through hole formed in the ceramic substrate, and at least one large diameter portion is included between the two openings of the through hole.

Wherein, the embedded portion is formed by a through hole or a groove formed on the ceramic base.

A manufacturing method of a ceramic plastic composite product, comprising the steps of: providing a ceramic substrate, wherein the ceramic substrate is provided with an embedded portion; and inserting and inserting an insert into the ceramic substrate to form an insert and the ceramic a body structure; forming a plating layer on the surface of the embedded portion by electrolytic plating.

The ceramic-plastic composite product forms a recessed or through-hole-shaped embedded portion on the ceramic substrate, and the ceramic is injected into the embedded portion to form a decorative pattern, and a plating metal layer is formed on the plastic surface by electroplating to make the ceramic The surface of the base body has a decorative effect of a metal pattern, so that the ceramic plastic composite product has a better decorative effect. Moreover, the specific formation of the embedded portion can be arbitrarily set, so that the decorative pattern formed by the plastic can also be varied, so that a plurality of combinations can be formed between the ceramic and the plastic.

3 is a first structural schematic view showing an embedded portion of a ceramic base of a ceramic-plastic composite product according to a preferred embodiment of the present invention.

4 is a schematic view showing the second structure of the embedded portion of the ceramic base of the ceramic-plastic composite product according to the preferred embodiment of the present invention.

Referring to FIG. 1 and FIG. 2 , a ceramic plastic composite article 100 according to a preferred embodiment of the present invention is exemplified by an application of an electronic device casing, comprising a ceramic substrate 10 and at least one insert 20 embedded in the ceramic substrate 10 . (See Figure 2).

The ceramic substrate 10 can be made of ordinary ceramic or reinforced ceramic, which constitutes a major component of the housing of the electronic device. The ceramic base 10 is provided with an embedded portion 12 (see FIG. 3) for embedding the insert 20 on the ceramic base 10. The embedded portion 12 can have a variety of shapes.

The embedded portion 12 may be formed by at least one through hole 122 formed in the ceramic base 10. The second opening 1221 of the through hole 122 includes at least a large diameter portion 1223. Of course, the through holes 122 can also be the same size. Referring to FIG. 3, the embedded portion 12 of the present embodiment is composed of a plurality of through holes 122 of different sizes. The embedded portion 12 can also be formed by at least one groove 124 formed on the ceramic base 10. The groove 124 has a wide groove bottom and a small notch (see FIG. 4).

The insert 20 is composed of a plastic filled in the embedded portion 12. The insert 20 is integrally formed with the ceramic substrate 10 by insert molding, and may be formed by selecting a relatively common injection molding resin such as polyvinyl chloride, polyethylene terephthalate or acrylonitrile-styrene. Butadiene copolymer, polycarbonate, polyimine, liquid crystal polymer, polyether phthalimide, polyphenylene sulfide, polyfluorene, polystyrene, ethylene glycol modified polyester and polypropylene polymer One or more. The insert 20 forms a decorative pattern, a character, a logo, and the like on the surface of the plastic substrate 10. When the material of the insert 20 is acrylonitrile-butadiene-Styrene (ABS), polycarbonate (PC), acrylonitrile-butadiene-styrene and polycarbonate mixture and Polyethylmethacrylate (PMMA), etc. When the electroplated plastic material is subjected to plating, a plating layer 30 may be formed on the surface of the insert 20 (see Fig. 3). The plating layer 30 is formed on the surface of the insert 20 exposed on the embedded portion 12 to obtain the metal appearance effect of the insert 20.

The manufacturing method of the above ceramic plastic composite article 100 comprises the following steps: First, a pre-made ceramic substrate 10 is provided. The ceramic substrate 10 can be formed by sintering a green body by powder pressure, and has the structure as described above, wherein the embedded portion 12 can be formed at the same time when the green body is molded, or can be formed by mechanical processing after sintering. .

Then, the insert 20 and the ceramic base 10 are integrally formed by insert molding in the insert portion 12 of the ceramic base 10. The material forming the insert 20 is acrylonitrile-butadiene-Styrene (ABS), polycarbonate (PC), acrylonitrile-butadiene-styrene and polycarbonate mixture and A plastic material that can be plated, such as polyethylmethacrylate (PMMA).

A plating layer 30 is formed on the surface of the insert 20 exposed to the embedded portion 12 by electrolytic plating.

The ceramic-plastic composite product 100 has a recessed or through-hole-like embedded portion 12 formed on the ceramic substrate 10, and the plastic is injected into the embedded portion 12 to form a decorative pattern, and a plating is formed on the plastic surface by electroplating. The metal layer has a decorative effect of the metal pattern on the surface of the ceramic substrate 10, so that the ceramic-plastic composite article 100 has a better decorative effect. Moreover, the specific formation of the embedded portion 12 can be arbitrarily set. Therefore, the decorative pattern formed by the plastic can also be varied, so that a plurality of combinations can be formed between the ceramic and the plastic.
