Description

Polyvinyl chloride metal coating painting, coating ingredients and manufacturing process thereof

The invention relates to the field of handicrafts, in particular to an improvement of a polyvinyl chloride metal coating, a coating composition and a manufacturing process thereof. Background technique

In order to improve the living conditions and tastes of life, or the decoration of public places or hotels, people hang various types of works of art on the walls. Craft painting is a form often used. Currently, there are various types of art paintings on the market. In particular, artistic paintings with metallic textures are more popular. In order to produce this type of art, people have made long-term explorations and proposed a variety of implementations. For example, casting from a pure metal into an art painting, or wrapping a metal layer on other materials. However, production costs are high, which is not conducive to mass production.

In addition, a kind of imitation porcelain plastic three-dimensional decorative painting disclosed in the Chinese patent document (application number -

CN92104578. 6), which is characterized in that the metal sheet is cut into the required specifications and then twisted by a bending cable to form a part of each shape in the overall picture, and then the non-oily paint putty which can be effectively combined with the surface is plastic coated. Abandoning the texture of the metal itself and at the same time obtaining further perfection of the shape, and drying them together in a special frame structure on which the positioning socket device is arranged, and at the same time using the putty having the above characteristics in the combination Complete the overall combination of the work on the frame surface and the local molding to make the picture achieve the three-dimensional relief effect. Finally, the surface of the dried product is painted with the imitation enamel paint combined with the common color to obtain the stand with various artistic effects. View the composition of the picture. The implementation steps of the above scheme are cumbersome, the production process is high, the cost is high, the metal texture of the screen is poor, and the stereoscopic effect is not strong. On the other hand, using a lot of metal, consumption Disclosure of invention

The invention mainly solves the technical problems that the production cost of the prior art is high, the metal texture of the picture is poor, the three-dimensional feeling is not strong, the service life of the material is not long, and the deformation is easy to occur once it is wet, and transportation is inconvenient; The utility model relates to a polyvinyl chloride metal coating which is low in production cost, easy to implement, strong in metallic texture, prominent in three-dimensional sense, and absorbs the advantages of polyvinyl chloride material, has long service life, is not deformed by moisture, and is easy to transport.

The invention also solves the technical problems of using the metal material to make the picture in the prior art, although the stereoscopic effect is good and the texture is real, but the metal is used, the metal material is consumed, the weight is large, and the handling and suspension are not convenient; It provides a PVC metal coating with a good metal texture, a good three-dimensional effect, and a light and reliable use.

The invention also solves the technical problem that the ratio of the coating ingredients existing in the prior art is not reasonable, the adhesion is poor, and the long-term use is easy to cause the lodging, etc.; and the ratio is reasonable and the adhesion is provided. Well, long-term use will not cause the coating ingredients of the cracked PVC metal coating.

Still another object of the present invention is to solve the technical problems in the prior art that the manufacturing process is complicated, the production efficiency is low, the time is long, the labor intensity is large, and the adhesion between the paint and the polyvinyl chloride material is not tight enough; The production process is simple, the production efficiency is high, the time is low, the labor intensity is low, and the coating of the PVC and the polyvinyl chloride material is closely adhered to the polyvinyl chloride metal coating painting process.

The above technical problem of the present invention is mainly solved by the following technical solution: a polyvinyl chloride metal coating painting process, which is characterized by the following steps: a: stamper: pressing a polyvinyl chloride material into a flat surface by using a mold Or a core with a concave-convex structure; b : a modulating paint: a metal Toner, volatile agent, and binder are mixed; C: Coating: Apply the prepared coating evenly to the outer surface of the PVC core; d: Coloring: After the coating is firmly adhered, Coloring is applied to the surface of the coating with a coloring agent depending on the condition of the pattern.

The present invention creatively coats a polyvinyl chloride material with a metallic coating which not only gives it a good metallic feel, reduces production costs, but also facilitates transportation and suspension. In order to facilitate the handling of the coating process, the present invention contemplates a suitable coating process step.

In order to better reflect the metallic texture of the coated layer, preferably, the metallic toner is a mixture of copper powder and gold powder, and the mass ratio of the copper powder to the gold powder is 6:4 to 8:2. The metal toners here can be of various types, and the effects of using different colors of metal powder are also different.

The particle size of the metal material not only affects the effect of the picture, but also has a great influence on the adhesion. 5: 3. 2~7. 2 : 2. 8; and the particle size of the copper powder and the gold powder is 1200 mesh ~ 1800 mesh.

The polyvinyl chloride metal coating obtained by the above method comprises a core, and a coating coated on the outer surface of the core, wherein the core is pressed by a polyvinyl chloride material, and the pattern has The concave-convex structure is coated with a non-ferrous metal coating on the outer surface of the core.

If the thickness of the metal coating is too small, scratching will cause scratches and affect the effect of the picture; if the metal coating is too thick, the production cost will increase, resulting in unnecessary cost increase. Preferably, the colored The thickness of the metal coating is 0. Ιπιπ! ~ 0. 3mm.

The above-mentioned polyvinyl chloride metal coating is painted with a coating material drawn of a polyvinyl chloride metal coating, It is characterized by comprising the following components of weight ratio: copper powder 40wt%~48wt%, gold powder 10wt%~20wt%, volatile agent 16wt%~18wt%, binder 20wt%~24wt%; and copper powder and gold powder The particle size is 1200 mesh to 1800 mesh.

In order to further improve the proportioning effect, preferably, the optimized weight ratio of the components is: copper powder 44wt%~46wt%, gold powder 13wt%~15wt%, volatile agent 17wt%~18wt%, binder 20wt%~22wt %.

The volatile agent herein may be variously used. Preferably, the volatile agent is any one or a combination of pine perfume, turpentine, ethanol, diacetone alcohol, and kerosene. The volatilizer here mainly takes away the water after the coating is applied, so that it is quickly dried, which helps the coating to adhere quickly to the outer surface of the core. Therefore, liquids with volatile energy can be used. Considering economy, environmental protection, and product quality, pine perfume is generally used as a volatile agent.

Preferably, the binder is an oil-based water-repellent binder, and the oil-based water-repellent binder is an acrylate copolymer. The oily waterproofing adhesive here can also be made of PS gold oil.

Preferably, the coloring agent is any one or a combination of iron oxide, chrome yellow, phthalocyanine blue, phthalocyanine green, titanium white powder, and carbon black. Of course, the dyes here can be of a wide variety of types.

Therefore, the invention has the following characteristics: 1. Low production cost, easy implementation, strong metallic texture, prominent three-dimensional effect, and absorption of the advantages of polychlorinated and vinyl materials; 2. long service life, no deformation caused by moisture, and convenient Transportation with a small amount of metal can obtain a better metal texture, good stereo effect, light and reliable; 3, simple production process, high production efficiency, less time, low labor intensity, close adhesion of paint and PVC material. Best way to implement the invention
