Problems solved by technology

In the process of providing processing nuts for foreign companies, foreign companies require domestic suppliers to provide value-added services of solid lubricating coatings when supplying nuts for the purpose of reducing costs. There is no precedent for large-scale application on the Internet, which has seriously affected the export of nut suppliers

Embodiment

[0020] The formula of solid lubricating coating is as follows:

[0021] Solid lubricant: 10% molybdenum disulfide, 3% polytetrafluoroethylene, 5% graphite, 1% graphene, 16% tungsten disulfide, 10% graphite fluoride;

[0022] Adhesive: 30% epoxy resin, 19% nitro resin;

[0023] Additive: powder surface treatment agent 6%;

[0024] Active additives are added to the solid lubricant to activate the surface of the solid lubricant so that it can better combine with the polymer material.

[0025] After mixing, the specific gravity is 1100±60 g / L, it is black, and the flash point is 100°C.

[0026] The specific steps of coating the solid lubricating coating on the nut are as follows:

[0027] The first step is to use a normal temperature neutral degreasing agent to thoroughly remove all kinds of grease, dust, oil stains and other micro-garbage on the nut during the machining process, and wash it with water. After washing with water, dry the surface of the workpiece with high-press...

Abstract

The invention relates to a screw cap with a solid lubricating coating. The lubricating coating is 15-30mum thick, and the solid lubricating paint comprises the following ingredients in percentage by weight: 2-12% of molybdenum disulfide, 3-6% of polytetrafluorethylene, 1-7% of graphite, 0-3% of graphene, 12-18% of tungsten disulfide, 8-12% of carbon monofluoride, 16-34% of epoxy resin, 18-29% of nitroresin, and 3-9% of paint additives. The lubricating coating has excellent self-lubricating property, and anti-loosening and anti-occlusion properties. The screw cap with the solid lubricating coating realizes low torque coefficient of 0.1-0.13, and high torque coefficient of 0.14-0.17, thereby meeting the special requirements of automobiles, shipbuilding, power generation and other industries on the screw cap.

Description

[technical field] [0001] The invention relates to a nut with a solid lubricating coating layer and a production method thereof. [Background technique] [0002] Nuts are used in a wide range of fields, almost in all aspects of the industrial field, and the annual usage is very large. However, anti-jamming, anti-loosening, and self-lubricating high-end nuts are still rare in the market, and there are even fewer studies in this area. [0003] The solid lubricating coating technology adopted by developed countries such as Europe and the United States in the 1980s has realized industrial production and has been widely used in industries such as automobiles, shipbuilding, and wind power generation. [0004] At present, the application of solid lubrication technology in the field of nuts has just started in China, and there are some small batches of processing and use, but there is still no large-scale industrial production and processing. In the process of providing processing n...
