3) calcined product, quick lime, carbon fiber, flyash, cyclodextrin, slag powders, silicon carbide whisker and zirconium silicate are mixed
Close so that gypsum material is made；
4) gypsum material and water are mixed to prepare calcium plaster, then the calcium plaster are coated on caly model,
Finally dry in the shade, demould so that the carbon fiber gypsum mold is made.
Invention further provides a kind of carbon fiber gypsum mold, which passes through above-mentioned method system
It is standby and obtain.
Through the above technical solutions, the present invention first lives gypsum, bamboo charcoal and attapulgite by hydrochloric acid solution
Change is handled, and then carries out calcining by filter cake so as to the calcined product activated, then fine by calcined product, quick lime, carbon
What the coordinate system between dimension, flyash, cyclodextrin, slag powders, silicon carbide whisker and zirconium silicate obtained excellent performance is gypsum material,
Finally the gypsum material is coated on caly model, finally dries in the shade, demould so that the carbon fiber gypsum mold is made.The carbon is fine
Dimension gypsum mold has excellent flexural strength, shock resistance and water resistance.The raw material in the above method is easy to get at the same time, and
Step is simply suitable for large-scale industrial production.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
