Problems solved by technology

Today's methods for preparing graphene, one is to use adhesive tape for micromechanical peeling, which is extremely inefficient and can only be used for the preparation of test samples; the other is to use concentrated sulfuric acid (or acetic acid, etc.) Potassium (perchloric acid, hydrogen peroxide, etc.) is used as an oxidizing agent, and the intercalation is first oxidized, then ultrasonically dispersed or expanded by microwaves, and finally reduced, which not only requires many operations, but also produces a large amount of washing sewage. Although it can be industrialized, the production cost and The cost of environmental pollution is very high, so its products can only be used in high-tech fields. It is obviously not cost-effective to use it as a raw material for cold stamping release agents
As for single-layer graphene, it is obviously not suitable for use as a raw material for cold stamping release agents.

preparation example Construction

[0050] A preparation method of a water-based graphite-based release agent: deacidify the water-based graphite and place it in a stirring container to obtain the de-acidified water-based graphite, take each component according to the weight percentage, add glycerol and coconut oil fatty acid under stirring Diethanolamide, after stirring evenly, add distilled water, continue stirring until uniform, then discharge, pack and store.

[0051] A method of using a water-based graphite-based release agent: according to the complexity of the structure of the stamping parts, it can be diluted with distilled water by different multiples of 0~10, that is, the more complex the structure of the stamping part, the lower the dilution factor until it is used directly. Apply by smearing or spraying.

Abstract

The invention discloses a water-borne graphite-based release agent as well as a preparation method and a usage method thereof. The release agent is prepared from the following components in percentageby weight: 28.17 to 50 percent of deacidified water-borne graphite, 0 to 20.94 percent of glycerol, 4.04 percent of coconutt diethanol amide and the balance of distilled water. The release agent disclosed by the invention has high lubricating capability; during cold stamping processing, no other solids are precipitated out except low-order graphite, so that the surface of a stamping finished product can be smooth, the service life of a mold can be prolonged, and the yield is high.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a water-based graphite-based release agent and methods for preparing and using the same. Background technique [0002] The metal cold stamping process requires the use of a release agent with high temperature resistance and strong lubricating ability. So far, the release agent with the best above-mentioned ability recognized by people is still graphite powder. In addition, graphite powder also has the advantages of abundant natural resources and low cost. However, there is a big disadvantage of using graphite powder as a cold stamping release agent, that is, graphite powder flies everywhere during use, which not only wastes graphite but also seriously pollutes the environment, and seriously affects the image and health of operators. For this reason, people have been looking for an alternative to using graphite powder with properties comparable to graphite powder. [0003] The ...
