Embodiment 1

[0029] This embodiment provides a surfactant for a workpiece, including deionized water, an interfacial complexing agent, a composite low-foaming surfactant, an antistatic agent, a water film spreading agent and an adhesion promoter, and each component is in a liquid state. That is to say, the surfactant is a surfactant liquid prepared by mixing deionized water, interfacial complexing agent, composite low-foaming surfactant, antistatic agent, water film spreading agent and adhesion promoter.

[0030] Specifically, the mass ratio of deionized water, interfacial complexing agent, composite low-foaming surfactant, antistatic agent, water film spreading agent and adhesion promoter in the surfactant is 60:4:8:2:5 :4.5.

[0031] Among them, sodium polycarboxylate is selected as the interfacial complexing agent, which can complex Ca in the surfactant liquid. 2+ , Mg 2+ Metal ions and other impurities have an excellent dispersion effect on the surfactant liquid or the solid particle...

Embodiment 2

[0043] This embodiment provides a surfactant for a workpiece, including deionized water, an interfacial complexing agent, a composite low-foaming surfactant, an antistatic agent, a water film spreading agent and an adhesion promoter, and each component is in a liquid state.

[0044] Specifically, the mass ratio of deionized water, interfacial complexing agent, composite low-foaming surfactant, antistatic agent, water film spreading agent and adhesion promoter in the surfactant is 70:6:10:8:6 :2.

[0045] Among them, the interface complexing agent chooses modified sodium ethyl naphthalene sulfonate, which has good surface activity and is often used as an emulsifier for moisturizing, penetrating factors, emulsification, and polymerization reactions, and can complex the interface Ca in active agent solution 2 + , Mg 2+ Metal ions and other impurities have an excellent dispersion effect on the surfactant liquid or the solid particles and oligomer gels on the surface of the work...

Embodiment 3

[0053] This embodiment provides a surfactant for a workpiece, including deionized water, an interfacial complexing agent, a composite low-foaming surfactant, an antistatic agent, a water film spreading agent and an adhesion promoter, and each component is in a liquid state.

[0054] Specifically, the mass ratio of deionized water, interfacial complexing agent, composite low-foaming surfactant, antistatic agent, water film spreading agent and adhesion promoter in the surfactant is 65:5:6:6:8 :4.

[0055] Among them, the interfacial complexing agent is potassium polycarboxylate, which can complex Ca in the surfactant liquid. 2+ , Mg 2+ Metal ions and other impurities have an excellent dispersion effect on the surfactant liquid or the solid particles and oligomer gels on the surface of the workpiece, so that the solid particles and oligomer gels will not adhere to the surface of the workpiece as much as possible. The composite low-foaming surfactant chooses the condensate of et...

Abstract

The invention relates to a surfactant used for workpieces, a preparation method thereof, and a workpiece surface spraying type pre-treatment method. The surfactant comprises deionized water, an interface complexing agent, a composite low-foam surfactant, an antistatic agent, a water film spreading agent, and an adhesion promoter at a mass ratio of 60-80:0-10:5-15:1-15:1-10:0.5-5. The antistatic agent is one or a composition of a plurality of ingredients selected from ethoxylated amines, ionic quaternary ammonium salts, tertiary amines, and carboxylates; the water film spreading agent is one ora composition of a plurality of ingredients selected from condensation products of alcohol ethers with ethylene oxide, fluorine containing surfactants, and carbon hydrogen surfactants. The surfactantcan be used for spraying at normal temperature, is capable of eliminating water stains and flow stains on the surfaces of workpieces, increasing the adhesion force of workpieces with paint. The preparation method and the workpiece surface spraying type pre-treatment method are simple in operation, and are suitable for large batch production.

Description

technical field [0001] The invention relates to a surface active agent for a workpiece, a preparation method and a spray type pretreatment method on the workpiece surface. Background technique [0002] After the surface of workpieces such as plastic parts or metals is painted, it can not only improve the appearance and decoration effect of the workpiece, such as color, smoothness, and texture, but also expand the use of the workpiece. Taking plastic parts as an example, coating the surface of a plastic part with a conductive layer can make it have the conductive properties of metal, and it can be widely used in communication, electronics and other fields. However, due to the inevitable adhesion of oil stains, sweat stains, dust, release agents and other impurities in plastic parts during injection molding, storage and transportation, as well as static electricity generated by friction, the adhesion performance of plastic parts is greatly reduced during surface coating. The ...
