Embodiment 2

[0030] The material of the hard layer includes 48%-63% boron nitride and 37%-52% zirconia; the material of the buffer layer includes 68%-70% soil, 20%-21% titanium dioxide, 6%- 7% acrylic acid, 2%-4% polypropylene fiber; the wear-resistant layer is made of alumina ceramics.

[0031] The preparation method of the ceramic ball:

[0032] (a) Weigh 48%-63% of boron nitride and 37%-52% of zirconia according to the mass percentage, and mix to obtain the first powder, perform a granulation to form the first spherical particles, and the hard layer spherical particles performing pre-sintering to form first spherical particles;

[0033] (b) Weigh 68%-70% of soil according to mass percentage; 20%-21% of titanium dioxide; 6%-7% of acrylic acid; 2%-4% of polypropylene fiber, mix and dry to obtain the second powder; The spherical particles of the hard layer are mixed with the second powder for secondary granulation, so that the second powder is evenly wrapped on the surface of the first s...

Abstract

The invention discloses a rubber ceramic compound lining plate which comprises a plurality of independent lining plate blocks; the independent lining plate blocks are matched with each other and formed into a lining plate main body; the lining plate main body is connected with a base plate; each lining plate block comprises a rubber layer and a ceramic layer; one side of the rubber layer is fixedly connected with the ceramic layer; the other side of the rubber layer is fixed with the base plate; a fastening part is embedded into each lining plate block; the ceramic layer is formed by a plurality of ceramic balls arrayed in parallel; each ceramic ball is composed of a hard layer, a buffering layer and a wearing layer from inner to outer.

Description

technical field [0001] The invention relates to the field of lining boards, in particular to a rubber-ceramic composite lining board. Background technique [0002] The rubber ceramic liner is usually inlaid with special ceramics in special rubber through vulcanization to form a square wear-resistant rubber liner, and then fixed on the substrate of the equipment by welding or pasting to form a wear-resistant layer, which is widely used in firepower The coal conveying and ash discharge system of the power plant and the silo, hopper and other equipment in the material conveying and batching system of the metallurgical iron and steel industry are used as wear-resistant linings. In order to ensure the performance of the wear-resistant lining, it must be ensured that the wear-resistant lining has excellent wear resistance, toughness, impact resistance, etc., and the connection between the wear-resistant lining and the base plate must be firm. However, in the prior art, most of th...
