Problems solved by technology

However, the above two coating systems are not hydrophilic and cannot be used on surfaces with hydrophilic requirements
[0004] Publication No. CN103555114A uses acrylic resin, sodium hydroxide neutralizer, amino resin curing agent, sulfonic acid catalyst, etc. The surface is coated with a film-forming substance, and the formed coating has good hydrophilicity, adhesion and corrosion resistance, but the coating has no self-lubricating function
[0005] Therefore, the coating system in the related art has the disadvantages of small thermal conductivity, low heat conduction efficiency, low hydrophilicity or self-lubricating property

Abstract

The invention provides a self-lubricating hydrophilic coating which comprises, by weight, 30-50 parts of self-lubricating mixed dispersion liquid, 60-85 parts of acrylic resin, 20-90 parts of water, 1-2 parts of antifoaming agents, 4-8 parts of dispersing agents, 0.5-1.2 parts of wetting agents, 0.5-1.8 parts of PH modifiers, 0.5-0.8 part of rheological agents and 0.5-2.5 parts of surfactants, wherein the self-lubricating mixed dispersion liquid comprises, by weight, 20-50 parts of hydroxyl acrylamide, 30-45 parts of allyl glycidyl ether, 25-50 parts of acrylic acid, 40-80 parts of graphene, 80-120 parts of water, 20-50 parts of propylene glycol monomethyl ether and 50-80 parts of ethylene glycol monobutyl ether. Compared with related technology, the self-lubricating hydrophilic coating has the advantages that heat conduction efficiency, hydrophilia and self-lubricating performance are all high.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical coatings, in particular to a self-lubricating hydrophilic coating and a preparation method thereof. 【Background technique】 [0002] Wear and tear in high-speed operating equipment will lead to equipment failure, damage or even scrapping. The protection and repair of wear-resistant parts is the most concerned issue in industrial equipment. In the manufacturing process of air-conditioning radiators, in order to reduce the wear and tear of equipment and the rate of defective products, lubricating oil is applied to the surface of the mold for surface treatment. On the one hand, the consumption of lubricating oil is large and the cost is high; on the other hand, lubricating oil is removed by post-baking The waste oil fume produced in the process will pollute the environment. If the hydrophilic aluminum foil is endowed with a lubricating function, it will not only reduce the consumption of lubricati...
