Embodiment 1

[0034] This embodiment provides a protective coating suitable for the surface of various substrates. The resin system of the coating contains a large number of hydroxyl groups, and these hydroxyl groups can form hydrogen bonds with ethanol and n-butanol, so it can be dissolved in ethanol and n-butanol middle. And the coating is made by mixing the following materials by weight and filtering them through a 80-100 mesh filter screen: 14-15 parts of vinyl resin, 14-15 parts of A181 polyketone resin, 37-38 parts of absolute ethanol , 15~16 parts of n-butanol, 0.4~0.6 parts of E44 epoxy resin, 0.8~1.2 parts of R~972 anti-settling agent, 12~13 parts of iron oxide red, 3~5 parts of talcum powder, 0.4~ 0.6 parts of Deqian dispersant of model 923S, 0.4-0.6 parts of Deqian defoamer of model 5500 and 0.2-0.5 parts of Deqian leveling agent of model 455,

[0035] The dispersant, defoamer and leveling agent used in this example are all produced by Deqian Chemical Co., Ltd. Any dispersant, ...

Embodiment 2

[0042] A kind of preparation method that is applicable to the protective coating of multiple base material surface is as follows:

[0043] (1) Take by weight 37.5 parts of absolute ethanol, 15 parts of n-butanol, 0.5 parts of E44 epoxy resin, 0.5 parts of 923S dispersant, 0.5 parts of 5500 defoamer, 0.3 parts of 455 fluid Leveling agent and 14.5 parts of A181 polyketone resin are added to the dispersion container, and dispersed for 25 minutes at a stirring speed of 200 rpm;

[0044] (2) Add 12 parts of iron oxide red and 3.5 parts of talcum powder in turn, and disperse for 50 minutes at a stirring speed of 500 rpm;

[0045] (3) Add the homogeneously dispersed slurry in step (2) into a conical mill and grind it to a fineness of 70 μm, and then add it to a dispersion container;

[0046] (4) Add 14.5 parts of vinyl resin and 1 part of R~972 anti-sedimentation agent, adjust the stirring speed to 800 rpm, continue stirring for 60 minutes, filter and pack with an 80-mesh filter to ...

Embodiment 3

[0049] A kind of preparation method that is applicable to the protective coating of multiple base material surface is as follows:

[0050] Preparation of a high-adhesion protective coating suitable for the surface of various substrates of power equipment:

[0051] (1) Take by weight 38 parts of absolute ethanol, 15.5 parts of n-butanol, 0.5 part of E44 epoxy resin, 0.5 part of 923S dispersant, 0.55 part of 5500 defoamer, 0.35 part of 455 fluid Leveling agent and 14.8 parts of A181 polyketone resin are added to the dispersion container, and dispersed for 20 minutes at a stirring speed of 300 rpm;

[0052] (2) Add 12.5 parts of iron oxide red and 4 parts of talcum powder in turn, and disperse for 40 minutes at a stirring speed of 800 rpm;

[0053] (3) Add the homogeneously dispersed slurry in step (2) into a conical mill and grind it to a fineness of 80 μm, and then add it to a dispersion container;

[0054] (4) Add 14 parts of vinyl resin and 0.9 parts of R-972 anti-sedimenta...

Abstract

The invention discloses a protective coating suitable for various base material surfaces and a preparation method thereof, and relates to the technical field of coatings. The invention provides a protective coating suitable for various substrate surfaces. The protective coating is mainly composed of absolute ethyl alcohol, n-butyl alcohol, vinyl resin, polyketone resin and the like. The protective coating provided by the invention is suitable for various materials of electrical equipment, such as inorganic materials (ceramic, concrete, cement, glass and the like), organic materials (such as polystyrene plastic, acrylic plates and the like), metals (cold-rolled steel plates, stainless steel plates and aluminum-coated zinc plates) and the like, and shows excellent adhesion to various base materials.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a protective coating suitable for the surface of various substrates and a preparation method thereof. Background technique [0002] In recent years, with the increasing level of power consumption, the safety and continuous power supply of the power grid is very important. The mechanical strength and insulation performance of outdoor electrical equipment caused by surface degradation, corrosion, and condensation of electrical equipment are one of the factors that affect the reliability of power systems. Coating protective coatings on the surface of electrical equipment is an effective way to protect the safe operation of electrical equipment. [0003] Commonly used materials for power equipment include many types, such as inorganic materials (ceramics, concrete, cement, glass, etc.), organic materials (such as polystyrene plastics, acrylic plates, etc.), metals (cold-rolled stee...
