Description
Technical field
The present invention relates to a kind of carbon fiber reinforcing tyre casting gypsum powder and preparation method thereof.
Background technology
In the thirties in 20th century, the Morris of U.S. Antioch institute, Bean Mr. and Mrs have found the foaming structure of Antioch gypsum.Development along with space flight, aviation, weapons, naval vessel industry, its related components day by day tends to integration, thin-walled property, maximization, complex-shapedization and becomes more meticulous, in the situation that adopt the processing means such as traditional mechanical workout, welding, riveted joint, forging, casting be very limited or can't process at all, the states such as U.S., day have developed foundry engieering-plaster mould casting of a kind of advanced person in the sixties in 20th century.
But also there are some technical barriers in plaster mould casting, such as intensity is low, make the precision of foundry goods and accurately finalize the design and be a greater impact, foundry goods volatility etc.; Poor thermal conductivity, cause foundry goods to produce pore, pin hole, tendency loose, shrinkage cavity large, and the coarse grains of foundry goods and mechanical property are descended.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and take carbon fiber and be raw material, high by its casting mould intensity of making, the carbon fiber reinforcing tyre casting gypsum powder of good heat conductivity.
The objective of the invention is to be achieved through the following technical solutions:
The present invention's carbon fiber reinforcing tyre casting gypsum powder, made by the raw material of following parts by weight: 10～15 parts, α gypsum, 15～25 parts, β gypsum, 17～23 parts of coal ash powders, 10～20 parts, carbon fiber, 0.001～0.002 part of retardant, 0.01～0.05 part of ammonium chloride, 0.2～0.5 part of defoamer.
Further, the particle diameter of described α gypsum, β gypsum, coal ash powder is respectively 10～20 μ m, 5～15 μ m, 20～35 μ m.
Further, the preferred chopped carbon fiber of described carbon fiber, length 2～5mm.
Further, described retardant can be methyl alcohol, ethanol or citric acid.
Further, described defoamer can be polydimethylsiloxane, silicone emulsion or natural fats and oils.
The preparation method of the present invention's carbon fiber reinforcing tyre casting gypsum powder, at first take each component raw material by described parts by weight, and then each component raw material is placed in to mixer and mixes 20～30min.
Described carbon fiber has the characteristics such as high strength, high-modulus, high temperature resistant, corrosion-resistant, antifatigue, creep resistance, conduction, heat transfer, belongs to typical new high-tech product, can be used for preparing advanced composite material.
The present invention's carbon fiber reinforcing tyre casting gypsum powder, the carbon fiber of take is main raw material, makes the intensity of products obtained therefrom high, and thermal conductivity is good, and other physicals and chemical property are also improved preferably; Its preparation method is simple, easy and simple to handle, and production cost is low, is conducive to suitability for industrialized production.
