Problems solved by technology

At present, the function of anti-corrosion coatings is relatively simple, and general anti-corrosion coatings only have anti-corrosion function. With the change of corrosion environment, the coating is required to not only have anti-corrosion function, but also to protect equipment from abrasion damage. The coefficient of friction is required small, wear-resistant
At the same time, it is required that the coating can be used in a higher temperature environment, and a single resin cannot meet such requirements. The coatings used now must be sprayed electrostatically, with small molecular residues and many organic volatile components. Pollution of the environment; poor flexibility, poor sintering performance, and poor wear resistance of coatings
Such as patent 98233680, only considered the non-stick properties of the coating without considering the wear resistance and anti-corrosion performance of the coating, and failed to solve the above problems

Embodiment 1

[0018] The paint is prepared according to the following composition ratio: (mass ratio):

[0019] The ratio of film-forming substances is:

[0020] Cellulose Nitrate 5%, Polyacrylic acid 10%, PTFE 35%, Ca 2 Al 2 Si 3 o 10 (OH) 2 (Anorthite) 5%

[0021] Al 2 Si 4 o 10 (OH) 2 (clay) 4%, KAlSiO 4 (potassium feldspar) 3%, FeO 2%, TiO 2 5%α-Al 2 o 3 21%, SiC 10%

[0022] The preparation process is as follows: after mixing the film-forming substance and the ceramic material evenly according to the above formula components, first add ketone and ester solvents to the film-forming substance), curing agents, dispersants, wetting agents and other additives, solvents The amount of addition is 1 / 4 of the total amount of film-forming substances and ceramic fillers, and then ceramic fillers are added to mix and disperse evenly. After grinding to the required average particle size of 25 μm to 50 μm, add the rest of the solvent, sieve, and pack.

[0023] The construction proce...

Embodiment 2

[0026] The paint is prepared according to the following composition ratio: (mass ratio):

[0027] Cellulose nitrate 15%, polyacrylic acid 15%, polytetrafluoroethylene 30%, low temperature ceramic powder 15%

[0028] TiO 2 5%, α-Al 2 o 3 20%

[0029] Appropriate amount of solvent, appropriate amount of dispersant and wetting agent

[0030] The preparation process is as follows: after mixing the film-forming substance and the ceramic material in proportion to the above-mentioned substances, first add solvents and additives to the film-forming substance. The amount of solvent added is 1 / 4 of the total amount of the film-forming substance and ceramic filler. , and then add ceramic fillers to mix and disperse evenly, grind to the required average particle size (5-50μm), add the rest of the solvent, sieve, and pack.

[0031] Construction technology is the same as embodiment 1.

Abstract

This invention adopts the ceramic material and Fluorine resin with moist slippery characteristic to mix altogether, it is wear-resisting to make one, it is warm to be able to bear, corrosion-resistant, do not glue the wear-resisting sizing of pottery of the function. It is become membrane material, ceramic packing, a piece of coating of one pair of groups made up of the solvent and solidification pharmaceutical, succeed the membrane material and include the cellulosic nitric acid ester, gather the acrylic acid. the mixture of three kinds of resin of the polytetrafluoroethylene (PTFE), low-temperature glass dust, the ceramic pcking makes up. Will become membrane material and solvent first while preparing, the solidification pharmaceutical will be mixed evenly, and then put into the ceramic packing, then adopts the disperse the equipment, after mixing evenly, processes in grinding the equipment, sieve, pack. It becomes membrane under normal atmospheric temperature, improve coating coating construction performance, adopt and brush and roll scribbling and spraying, overcome coating must adopt static shortcoming of spraying at present, become low temperature products after the membrane, the high temperature frits again, any little member does not remain materials, has guaranteed this application in the tableware and wear-resisting trade of coating.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a self-lubricating anti-adhesive coating and a preparation method thereof. Background technique [0002] During the use of metals, in order to prolong the service life, it is necessary to treat the surface to be corrosion-resistant, wear-resistant, temperature-resistant, and have a low friction coefficient. At present, the function of anti-corrosion coatings is relatively simple, and general anti-corrosion coatings only have anti-corrosion function. With the change of corrosion environment, the coating is required to not only have anti-corrosion function, but also to protect equipment from abrasion damage. The coefficient of friction is required Small and wear-resistant. At the same time, it is required that the coating can be used in a higher temperature environment, and a single resin cannot meet such requirements. The coatings used now must be sprayed electrostatically, with small mol...
