Resin-permeable porous ceramic composite material as well as preparation method and application thereof
The invention discloses a resin-permeable porous ceramic composite material and a preparation method and application thereof.The composite material is prepared from mixed powder of lead-free low-melting-point glass powder and silicate powder according to the mass ratio of (1-20): (80-99) as a raw material, two-time compression molding is adopted, sintering is conducted at the temperature of 500-650 DEG C, the Vickers hardness mean value of the material is 1.6 GPa or above, and the resin-permeable porous ceramic composite material is prepared. The average value of elasticity modulus is 25 GPa or above, the average value of fracture toughness is 1.5 MPa.m < 1/2 > or above, the defective rate of the material in production can be as low as 2.3%, and compared with an existing ceramic resin composite material prepared from silicate powder as a raw material, the defective rate of the material is obviously reduced, and the service life of the ceramic resin composite material is prolonged. The defective rate is reduced by about 50%, and the mechanical property of the material at the sintering temperature of 500-650 DEG C can be kept equivalent to or even better than that of the existing material sintered at the temperature of 700-800 DEG C.
本发明公开了一种树脂渗透多孔陶瓷复合材料及其制备方法和应用，所述复合材料，以无铅低熔点玻璃粉体与硅酸盐粉体按照质量比为1～20:80～99混合粉体为原料，采用两次压制成型，在500～650℃条件下烧结，材料的维氏硬度均值在1.6GPa以上，弹性模量均值在25GPa以上，断裂韧性均值在1.5MPa.m1/2以上，生产中材料次品率可低至2.3％，相比现有以硅酸盐粉体为原料制备的陶瓷树脂复合材料，材料的次品率明显降低，次品率降低约50％且能够在500～650℃烧结温度下保持材料力学性能与现有700～800℃烧结的力学性能相当，甚至更优。
