Example 1

Embodiment 1 provides a composite printing plate comprising a plastic core 1, a first metal foil 3 and a second metal foil 6. The plastic core plate 1 can be a PP plate, a PE plate or a PVC plate, or other formable plastic plates, and the thickness of the plastic core plate 1 is 2-30mm, so that the plastic core plate has enough strength and meets the process requirement of compounding with metal foil. The first and

second metal foils

3, 6 have a thickness of 0.1-0.5mm in order to have sufficient strength and to meet the process requirements for compounding with the plastic core 1. The first metal foil 3 and the second metal foil 6 are made of copper, iron or aluminum, and the first metal foil 3 and the second metal foil 6 may be made of the same material or different materials. The first metal foil 3 is adhered to one side surface of the plastic core plate 1 through an adhesive 2, and the second metal foil 6 is adhered to the other side surface of the plastic core plate 1 through the adhesive 2. The adhesive 2 can be a hot melt adhesive, a PUR adhesive, a single-component or two-component glue, or the like. The side of the first metal foil 3 far away from the plastic core plate 1 is provided with a first paint coating 4 suitable for printing, and paint can be coated on the surface of the first metal foil 3 in a roller coating baking mode to form the first paint coating 4 with the thickness of 12-16 microns, so that the first paint coating 4 has very good adhesion with printer ink, a printed pattern is clear and firm, and the printed pattern can be used outdoors without fading.

A first protective film 5 is arranged on the side of the first paint coat 4 facing away from the plastic core 1. The first protective film 5 is mainly used for protecting the surface of a product from scratching before use by a customer.

A second paint coating 7 is provided on the side of the second metal foil 6 remote from the plastic core 1. When double-sided printing is performed, the second paint coating 7 is the same as the first paint coating 4, so that ink can be attached conveniently; when the printing is single-sided printing, the second paint coat 7 may be ordinary paint, and does not need to have ink adhesion. When the double-sided printing is carried out, a second protective film 8 is arranged on the side face, far away from the plastic core plate 1, of the second paint coating 7, so that the surface of a product is protected and scratch and abrasion are prevented.

The production process of the composite printing plate of the embodiment comprises the following steps: firstly, uniformly coating printing paint on the surface of a metal foil in a roller coating mode to form a paint coating; secondly, dividing the metal foil coated with the paint coating into an upper layer and a lower layer, compounding the upper layer and the lower layer with the adhesive 2 and the plastic core plate 1 at one time through certain temperature and pressure to form a composite printing plate; and finally, coating a layer of protective film on the composite printing plate, and cutting to length.

The composite printing plate of the embodiment has the following advantages:

1. the first paint coating 4 suitable for printing can be directly printed, so that the process of compounding the printed back adhesive film/paper with a KT lining board is avoided, and the bubbling problem in the compounding process is also avoided;

2. the metal foil and the plastic core board 1 are formed in a compounding mode at one time, so that the board is very small in size error and very high in flatness, and the warping degree after long-time use is very small, and the board is not easy to deform and wear;

3. because the first paint coating 4 is formed by adopting the high-performance printing paint, the paint can be directly used outdoors, is not afraid of rain, cold, heat and ultraviolet rays, and cannot have the problems of fading, deformation and the like, wherein if the paint is double-sided printing, the second paint coating 7 is also formed by adopting the high-performance printing paint;

5. the cost performance is high, and the composite product of the metal foil and the plastic core plate 1 has the metal high-grade property and the economical and practical property of plastics;

6. the composite printing plate has wide application, and can be used as an advertisement printing material, decoration and furniture building material.

7. The printing can be carried out on two sides, the second paint coating 7 can be made on the surface of the second metal foil 6 by adopting printing paint according to the requirements of customers, and the second protective film 8 is applied.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
