Abstract

Provided are carbon fiber reinforcing tyre casting gypsum powder and a preparation method thereof. The gypsum powder is prepared by the following raw materials by weight: 10-15 parts of alpha gypsum, 15-25 parts of beta gypsum, 17-23 parts of coal ash powder, 10-20 parts of carbon fiber, 0.001-0.002 part of retarder, 0.01-0.05 part of ammonium chloride and 0.2-0.5 part of antifoaming agents. The preparation method of carbon fiber reinforcing tyre casting gypsum powder is further provided. Products manufactured by the carbon fiber reinforcing tyre casting gypsum powder are high in product strength, good in heat-conducting performance, and good in physical performance and chemical performance. The preparation method is simple, easy to operate, low in production cost and beneficial to industrialized production.

Description

technical field [0001] The invention relates to a carbon fiber reinforced tire casting gypsum powder and a preparation method thereof. Background technique [0002] In the 1930s, the Morris and Bean couples of Antioch College in the United States discovered the foaming structure of Antioch gypsum. With the development of aerospace, aviation, weapons, and shipbuilding industries, their related parts tend to be integrated, thin-walled, large-scale, and complex in shape. Traditional machining, welding, riveting, forging, casting When the processing methods are greatly limited or cannot be processed at all, the United States, Japan and other countries developed an advanced casting technology-gypsum casting in the 1960s. [0003] However, there are also some technical barriers in gypsum casting, such as low strength, which greatly affects the precision and accurate shaping of castings, and the variability of castings, etc.; poor thermal conductivity, resulting in large tendencie...
