Embodiment 1

[0030] A kind of wear-resisting coating of the present invention, comprises the following composition by weight percentage:

[0031] Unsaturated polyester varnish 43%

[0032] Mineral spirit 30%

[0033] Hardener 8%

[0034] Auxiliary 6%

[0035] Wax powder 1%

[0036] Silicone resin 2%.

[0037] The use of silicone resin in powder coatings can improve its heat resistance and weather resistance, but the use of silicone resin alone has problems such as high price and poor adhesion to the substrate. Therefore, silicone resins are often used to modify other organic resins, which can combine the advantages of silicone resins and other organic resins to make up for their shortcomings, improve the weather resistance and heat resistance of the paint film, and obtain powder coatings with excellent performance;

[0038] Ultra-fine wax powder has a very low melting point and is not easy to disperse. Silicon material or sili...

[0047] Mineral spirit 32%

[0048] Curing agent 9%

[0049] Auxiliary 6.5%

[0050] Wax powder 1.5%

[0051] Silicone resin 3%.

[0052] The auxiliary agent is selected from a combination of polyacrylate polymers, polymer silicones, and fluorine-modified acrylate polymers.

[0053] The curing agent is composed of 93-97wt% polyamide curing agent and 3-7wt% m-phenylenediamine curing agent.

[0054] The wax powder is ultra-fine wax powder reaching micron level.

[0055] Described solvent oil is No. 200 solvent oils.

[0056] The preparation method of wear-resistant coating of the present invention, comprises the steps:

[0057] (1) At room temperature of 28°C, weigh the above components by weight, mix...

Embodiment 3

[0061] The difference between embodiment 3 and embodiment 1 is: a kind of wear-resisting coating, it is characterized in that comprising the following composition by weight percentage:

[0062] Unsaturated polyester varnish 47%

[0063] Mineral spirit 35%

[0064] Curing agent 10%

[0065] Auxiliary 7%

[0066] Wax powder 2%

[0067] Silicone resin 4%.

[0068] The auxiliary agent is selected from one or a combination of polymer silicone, fluorine-modified acrylate polymer or silicon dioxide auxiliary agent.

[0069] The curing agent is composed of 97wt% polyamide curing agent and 7wt% m-phenylenediamine curing agent.

[0070] Described solvent oil is No. 180 solvent oils.

[0071] The preparation method of wear-resistant coating of the present invention, comprises the steps:

[0072] (1) At room temperature of 30°C, weigh the above-mentioned components by weight, mix the emulsified silicone resin, additives, and wax powder, and stir wi...

Abstract

The invention discloses a wear-resistant coating. The wear-resistant coating comprises the following components in percentage by weight: 43 to 47% of unsaturated polyester varnish, 30 to 35% of solvent oil, 8 to 10% of curing agent, 6 to 7% of assistant, 1 to 2% of wax powder, 2 to 4% of organic silicon resin, wherein the assistant is selected from one or the combination of some of polyacrylate polymer, macromolecule organic silicon, fluorine modified acrylate polymer or silicon dioxide assistants. The wear-resistant coating is prepared under normal temperature, and has outstanding performances like insulating performance, wear resistance, anti-permeability, super moisture resistance, electricity leakage preventing performance, super moisture resistance, vibration resistance, dust proofing performance, corrosion resistance and ageing preventing performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a wear-resistant coating and a preparation method thereof. [0002] Background technique [0003] With the continuous development of the economy, under realistic conditions, such as chemical environment, vibration, high dust, salt spray, humidity and high temperature, etc., building materials, metal surfaces, wood surfaces, circuit boards and the surface of objects that need to be protected are likely to produce Corrosion, softening, deformation, mildew and other problems lead to a reduction in service life. The chemical environment mainly refers to fuels and coolants. [0004] For example, the circuit board and its related equipment will fail in order to avoid the erosion of the environment. If the wear-resistant coating is applied to the surface of the circuit board to form a special protective film, it can protect the circuit under the above harsh conditions. free from damage. The ...
