Vacuum electroplating water-based coating

Abstract

The invention discloses vacuum plating water-based paint and belongs to the field of chemical paint. The paint is prepared by the following raw materials by weight percentage: 10-30% of epoxy resin, 30-45% of acrylic resin, 15-18% of amino resin, 1-3% of assistant, 2-5% of nano colloid, 1-3% of a waterproof uncoupling agent and the balance of deionized water. With the adoption of the scheme, the vacuum plating water-based paint has the characteristics of low cost, environmental protection, safety, innocuity and uniform coating.

Description

technical field [0001] The invention belongs to the technical field of chemical coating vacuum electroplating, and in particular relates to a water-based coating suitable for vacuum electroplating on the surface of glass products and a preparation method thereof. Background technique [0002] At present, the surfaces of many daily-use glass products such as wine bottles, perfume bottles, lighting glass, and art glass are coated with coatings. Midea's strong pursuit. In the prior art, electroplating is to coat glass products by spraying or water electroplating. Although it can meet people's needs to a certain extent, there are also some shortcomings. 1. Water electroplating The processing time is long, the production efficiency is low; the material utilization rate is low, the demand for water resources and metal resources is large, and the process loss is serious; the waste liquid pollutes the environment, and a large amount of waste liquid needs to be treated, which increas...

[0002] At present, the surfaces of many daily-use glass products such as wine bottles, perfume bottles, lighting glass, and art glass are coated with coatings. Midea's strong pursuit. In the prior art, electroplating is to coat glass products by spraying or water electroplating. Although it can meet people's needs to a certain extent, there are also some shortcomings. 1. Water electroplating The processing time is long, the production efficiency is low; the utilization rate of materials is low, the demand for water resources and metal resources is large, and the process loss is serious; the waste liquid is more polluting to the environment, and a large amount of waste liquid needs to be treated, which increases the cost

2. The processing requirements of spraying are relatively strict, and the operating level of operators is high, and it is easy to cause uneven coating thickness and affect the appearance effect; waste of electroplating solution, a large amount of electroplating solution is not covered on the substrate

3. The electroplating solution contains a large amount of hexavalent chromium ions, causing serious harm to workers

[0003] Moreover, most of the glass coatings currently on the market are oil-based coatings, the ingredients of which are mainly from petrochemical products, and the solvents are mostly organic solvents, which contain formaldehyde and free TDI And xylene and other toxic substances, these substances are continuously emitted during the production process and use of glass coatings, which not only cause environmental pollution, but also damage human health. After curing, oily glass coatings generally have tolerance, toughness and wear resistance. poor problem
