Novel printing technology of low-temperature bright golden pattern paper

Abstract

The invention discloses a novel printing technology of low-temperature bright golden pattern paper. The novel printing technology is characterized in that aiming at the defect of traditional bright golden pattern paper and the recent development trend of the bright golden pattern paper, a substitute of golden paste is researched to reduce the production cost and the product price; a substitute of pigment containing harmful heavy metal objects such as lead, cadmium and lithium and the recycling of byproducts during printing are researched to avoid resource waste; low-temperature enamel firing adhesion is researched to reduce energy source consumption, the breakage rate of attached objects and atmospheric pollution; a driving roller which is used for carrying out heat sealing on a heat-sealed material is appropriate in hardness, is good in elasticity and toughness and can be kept smooth in a long time, and the heat-sealed material is enabled to be uniformly heated. According to the novel printing technology disclosed by the invention, through the design concept of energy conservation and emission reduction, environment protection and low carbon economy, the defect in a traditional technology is improved, and the performance of products in aspects such as abrasion resistance, high temperature resistance and safety is effectively increased.

Description

technical field [0001] The invention relates to a new technology for printing low-temperature bright golden decal paper. Background technique [0002] Bright gold decal paper has the characteristics of high strength, high temperature resistance, friction resistance and bright color. The products are widely used in ceramics, glass ornaments and other products. If the traditional method is used to prepare bright gold decal paper, there are the following deficiencies: (1) the composition of the gold paste is mainly precious metal gold, and the price is high, resulting in high production costs and product prices; (2) this bright gold decal paper adopts Pigments contain heavy metals such as lead, cadmium, and lithium, which are harmful to the health of consumers; (3) the precious metals in the gold paste that are not printed on glass and ceramics in the pattern gap cannot be recycled, resulting in waste of resources; (4) cover film It cannot be torn, that is, it cannot be reused...

Problems solved by technology

If the traditional method is used to prepare bright gold decal paper, there are the following deficiencies: (1) the composition of the gold paste is mainly precious metal gold, and the price is high, resulting in high production costs and product prices; (2) this bright gold decal paper adopts Pigments contain heavy metals such as lead, cadmium, and lithium, which are harmful to the health of consumers; (3) the precious metals in the gold paste that are not printed on glass and ceramics in the pattern gap cannot be recycled, resulting in waste of resources; (4) cover film It cannot be torn, that is, it cannot be reused, resulting in waste of resources; (5) Large energy consumption: gold paste needs to be baked at high temperature to tightly adhere to the attached object (ceramic, glass, etc.), and the glass bright gold decal paper must be at 520 ° C Bake in a kiln at ~580°C, ceramic bright golden decal paper must be baked in a kiln at about 900°C, during the baking process, consume a lot of energy such as electricity and natural gas; (6) High temperature bright golden decal paper Due to temperature requirements, the application is limited, and it cannot be used for exquisite pattern decoration on metal, plexiglass and other products. Polyethylene and other substances are volatilized by pyrolysis, which is likely to cause air pollution; (8) Since the driving roller of the laminating machine is made of metal and has high hardness, it is difficult to make the surface very smooth, especially after a period of use. There will be some deformation on the surface, and its lack of elasticity and toughness, so it is easy to cause uneven heating of the heat-sealed material, and even some areas cannot achieve the purpose of heating, and the heat-sealing effect is poor
