Abstract
The invention discloses a kind of high ceramic material of compression strength, it is made up of following raw material according to parts by weight：1.5 5 parts of 15 28 parts of building castoff, 8 15 parts of quartz sand, 5 14 parts of corundum, 14 30 parts of nano-metal-oxide, 2.5 5 parts of carborundum, 1.5 6 parts of boron nitride, 1.5 4.5 parts of alumina silicate fibre, 38 parts of paraffin, 7 19 parts of phenolic resin, 4 10 parts of tetrabutyl titanate, 26 parts of reinforcing fiber, 48 parts of cocoanut shell and xylitol.The present invention also disclosed the preparation method of the ceramic material.Extensively, preparation technology is simple, it is adaptable to large-scale industrial production for raw material sources of the present invention；Each component plays synergy in the present invention, using grinding, ball milling and scattered so that material is well mixed, and is then calcined under elevated pressure conditions, the compression strength, bending strength and fracture toughness for obtaining material are significantly better than existing product, with wide market prospects.
Description
Technical field
The present invention relates to field of new materials, the high ceramic material of specifically a kind of compression strength.
Background technology
Ceramic material is the class inorganic non-metallic material being made with natural or synthetic compound by shaping and high temperature sintering
Material.It has the advantages that high-melting-point, high rigidity, resistance to oxidation, can be used as structural material, cutter material, because ceramics also have certain
A little special performances, but also as functional material.Crystal grain is difficult to slide in traditional ceramic material, and material matter is crisp, sintering temperature
It is high.The crystallite dimension of nano ceramics is small, and crystal grain is easily moved on other crystal grain, the nano ceramics material developed using nanometer technology
Material is that existing ceramics are modified using nano-powder, by toward ceramics in add or generation nano-scale particle, whisker, chip
Fiber etc., makes crystal grain, crystal boundary and the combination between them all reach nanometer level, makes the intensity, toughness and superplasticity of material
Increase substantially.
Nonmetallic wear-resistant ceramic material can be applied to metal surface and be used as wear-resisting, refractory layer, " hydration knot conventional at present
It is legal " the nonmetallic wear-resistant ceramic material of production, the method generally mixed using cement with water at normal temperatures, then again by cement with
The mixture of water carries out mixing the resistance to of some strength with the aggregate in wear-resistant ceramic material, micro mist, dispersant, steel flat flanges
Ceramic material is ground, the wear-resistant ceramic material compressive resistance of this method production is poor, and waste water resource increases production cost, expends
Labour, this just brings inconvenience for the use of people.
