Problems solved by technology

However, in actual use, since the invention uses clear water as the dispersion medium, the combination of the sprayed water-based graphite lubricant and the refractory fiber cloth is not good and uneven, and prefabrication into rolls cannot be realized. It must be sprayed immediately, which deteriorates the on-site operation. surroundings

Abstract

The invention relates to the technical field of composite materials and discloses a fiber cloth composite material with a graphite coating. The fiber cloth composite material comprises a refractory fiber cloth and a graphite slurry coating applied to one side of the refractory fiber cloth, wherein graphite slurry in the graphite slurry coating comprises the following raw materials in parts by weight: 100 parts of deionized water, 5-15 parts of graphite powder, 10-30 parts of sodium polyacrylate mixed liquid and 10-20 parts of a water-dispersible polyacrylate emulsion. The invention further discloses a preparation method of the composite material. The graphite slurry is evenly applied to one side of the refractory fiber cloth and is subjected to drying treatment to obtain the fiber cloth composite material with the graphite coating. Based on a fabric coating finishing technology, the graphite slurry coating is firmly combined with the refractory fiber cloth, so that the fiber cloth composite material with the graphite coating can be prefabricated in rolls and achieves the effects of a good lubricating effect, a simple preparation process and low cost and the effect of effectively reducing the forming force of die forgings.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a graphite-coated fiber cloth composite material and a preparation method thereof. Background technique [0002] At present, in the hot die forging process of metal materials, the high temperature lubrication of the die is very important for the smooth demoulding of the forging. Based on the background that metal materials hot forging lubricants are mostly graphite-based lubricants, a variety of water-based graphite-based hot forging lubricants have been successfully developed at home and abroad, such as China's MD-2, MD-7 series lubricants and American Dug-31, West Germany's Delta-144, etc. Among them, the graphite lubricant disclosed in patent CN1570049A is mainly composed of graphite micropowder, methyl cellulose, sodium methylene disodium sulfonate, sodium silicate and surfactant, and has good high-temperature lubricating properties; the water-based graphite disc...
