Problems solved by technology

Bonded solid lubricating coatings have the advantages of low friction coefficient, wide applicable temperature range, cheap price, and simple operation, but most of the binders in bonded solid lubricants are dissolved by organic solvents. A large amount of organic solvents and volatile organic compounds (VOC) are also used in the dispersion process of fillers, which are toxic and flammable, and cause serious harm to the environment and human body

Embodiment 1

[0030] Example 1: Weigh 10 grams of molybdenum disulfide, 5 grams of graphite, 3 grams of antimony trioxide, 5 grams of copper oxide, 0.1 gram of wax powder, 0.1 gram of polyethylene glycol, 0.1 gram of organic bentonite, and add 50 grams of water to carry out Ball milling, ball milling for 20 hours, disperse to the required particle size, take out, then add 10 grams of water-based epoxy emulsion, 10 grams of water-based curing agent, and stir for 10 minutes to form a water-based dry film lubricant spray. Under the air pressure of 0.1-0.3MPa, it is sprayed on the surface of the sandblasted stainless steel object with a thickness of 20-25μm. Let stand at room temperature for 1 hour. Slowly raise the temperature to 60°C, cure for two hours, then raise the temperature slowly to 100°C, and cure for two hours to obtain a water-based epoxy bonded solid lubricating coating.

Abstract

The invention discloses an aqueous epoxy adhering solid lubricant. The lubricant is composed of bi-component aqueous epoxy resins, a solid lubricant, a wear-resisting agent, a surface active agent, an antiseptic agent, an anti-sedimentation agent and water. The lubricant can be coated on the surfaces of processing workpieces such as stainless steel, carbon steel, alloy and the like. The lubricant is characterized in that water is adopted as a solvent, which has no pollution and no damage on bodies of painting constructors; and the coating has the advantages of good antifriction property and excellent physicochemical properties, and can replace an organic solvent type solid lubricant to be used on slide parts of multiple mechanical devices.

Description

technical field [0001] The present invention relates to a water-based epoxy bonded solid lubricant, describing a water-based epoxy bonded solid lubricant that is environmentally friendly, does not contain volatile organic compounds (VOC), and has excellent friction-reducing and wear-resisting properties. The prominent feature of this kind of bonded solid lubricant is that it is non-polluting, and the coating has good anti-friction and anti-wear properties and excellent physical and chemical properties. Background technique [0002] Bonded solid lubricating coating is a solid lubricating film with a thickness of about 20-30 microns. It uses binders to adhere solid lubricants, anti-wear agents, anti-corrosion agents and other fillers to the surface of parts to make relative movement The friction coefficient between the surfaces is reduced, and the wear is reduced, thereby playing the role of reducing friction, anti-wear, and anti-corrosion. Bonded solid lubricating coatings h...
