Embodiment 1

[0052] Take 100 parts of hydroxyl-terminated polyorganosiloxane with a viscosity of 2000mpa.s, 100 parts of diluent acetone solution, and stir evenly in a closed mixer at normal temperature and pressure; then add 40 parts of reinforcing filler, plasticizer 20 parts of simethicone oil, 0.5 parts of colorant, and 10 parts of heat-resistant agent continue to stir; under the protection of nitrogen, add 2 parts of stabilizer, 5 parts of crosslinking agent, and 2 parts of catalyst and mix well to obtain silicone coating A1, seal save.

[0053] Coat the silicone coating A1 on the aluminum substrate, test the surface drying time of the silicone coating A1, form the silicone coating C1 after curing, and test the tensile properties of the silicone coating C1.

Abstract

A silicone coating for electroplating, comprising: a hydroxyl-terminated polyorganosiloxane, a reinforcing filler, a crosslinking agent, and a catalyst, wherein a diluent is added to the silicone coating, and the diluent is a volatile organic Solvent; based on 100 parts by weight of hydroxyl-terminated polyorganosiloxane, the content of the above components is: reinforcing filler: 0-100 parts by weight; crosslinking agent: 0.5-20 parts by weight; catalyst: 0.05-10 parts by weight parts by weight; diluent: 100-300 parts by weight. The present invention also relates to a preparation method of the above-mentioned organosilicon paint, and using the organosilicon paint as a protective coating for electroplating. The organosilicon coating provided by the invention has excellent storage and operability. By adding a diluent to the system, it can be operated for more than 4 hours before coating, and the curing time of the coating after coating is 10 to 15 minutes. It is suitable for use in electroplating. The non-plated areas are coated.

Description

technical field [0001] The invention relates to the field of organosilicon materials, in particular to an organosilicon paint and a preparation method thereof, and also to a protective coating for electroplating formed by the organosilicon paint. Background technique [0002] Electroplating is a process of attaching a layer of metal film on the surface of metal or other material products by using the principle of electrolysis, which can prevent surface corrosion of products, improve wear resistance, conductivity, reflectivity and enhance aesthetics. According to the effect that the product needs to achieve, there will be a choice to electroplate the local area of ​​the product (electroplating area). However, in the process of operation, it is difficult to avoid sputtering the electroplating solution on the non-electroplating area. To protect the electroplating area, the existing method is to cover the non-electroplating area with a film or apply an adhesive. However, when t...
