Embodiment 1

[0025] The antibacterial and antiviral treatment process of the workpiece includes the following steps:

[0026] First of all, the surface of the workpiece is pretreated, and different pretreatment steps are performed according to the material of the workpiece. For aluminum alloys, magnesium aluminum alloys, magnesium lithium alloys, stainless steel and plastic-coated parts of these alloys, grinding and Oxidation treatment step, wherein the plastics in the plastic lagging are mainly polyphenyl sulfide resin, polyphenyl sulfide resin containing glass fiber, polybutylene terephthalate and polyterephthalate containing glass fiber Butylene formate;

[0027] Then, spray the primer on the pretreated workpiece surface. The primer is prepared from 40kg of acrylic resin, 20kg of amino resin, 5kg of butyl ester, 5kg of ethylene glycol butyl ether, 2kg of cellulose acetate butyrate additive, and 2kg of pigment. After primer, bake at 100°C for 20 minutes to dry, so that a primer layer wi...

Abstract

The invention discloses an antibacterial and antiviral treatment process for a workpiece. The antibacterial and antiviral treatment process comprises the following steps: S1, pretreating the surface of the workpiece; s2, primer is sprayed on the surface of the pretreated workpiece, and the workpiece is dried by baking; s3, colored paint is sprayed on the primer and dried; and S4, spraying an antibacterial coating on the surface of the colored paint, and drying. The antibacterial coating is prepared from 8-10 parts by weight of an antibacterial agent and 90-92 parts by weight of feed liquid, and the antibacterial agent is prepared from the following raw materials in parts by weight: 0.5-1 part of organosilicon quaternary ammonium salt, 1-2 parts of nano zinc and 2-3 parts of an auxiliary A. The defects in the prior art are overcome; after the primer, the colored paint and the antibacterial coating are sprayed, the surface of a workpiece has antibacterial performance, and the wear resistance, the hardness and the wiping resistance of a coating are maintained.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to an antibacterial and antiviral treatment process for workpieces. Background technique [0002] Surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. For metal castings, the more commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, surface spraying, etc. In the prior art, after the general coating is sprayed on the surface of the workpiece, the surface of the workpiece has no antibacterial and anti-virus function, and after adding antibacterial materials in the coating, the durability of the coating will be seriously reduced. Contents of the invention [0003] The object of the invention is to provide an antibacterial and antiviral treatment process for workpieces, which overcomes the deficiencies of the prior art. [0004] In ...
