Problems solved by technology

[0003] (1) The wear resistance is not good, and the damage rate of its surface is very high under the wear and tear of automobiles and other vehicles;
[0004] (2) The strength is not high, and the corners will be broken under the heavy pressure of vehicles such as cars;
[0005] (3) Poor drainage performance, easy to accumulate water
Because the above-mentioned problems exist in the concrete pavement brick in the prior art, so its use effect is not ideal enough yet

preparation example Construction

[0042] A kind of preparation method of wear-resistant pavement brick provided on the one hand, the preparation method of described wear-resistant pavement brick is as follows:

[0043] Step (1): Uniformly mix granite, silica-alumina, water reducer, hollow glass microspheres, mullite, lead oxide ceramic particles, binder and proppant according to the component content to obtain mixture A;

[0044] Step (2): Use a ball mill to grind the mixture A, add 2-4 times the weight of the above-mentioned mixture to the water and stir evenly, pump the pulp, and squeeze out the water by 85-90% through the filter in the mud squeezer %;

[0045]Step (3): Squeeze out the moisture and stack it indoors for 24-36 hours to rot, put it in a mud mixer for rough refining, discharge the air in the components, and place it indoors for 24 hours, and then squeeze it out through a mud mixer and a mold ;

[0046] Step (4): Sintering at a high temperature of 1200-1300°C, cutting into semi-finished product...

Embodiment 1

[0054] One aspect of this embodiment provides a wear-resistant pavement brick. The wear-resistant pavement brick includes the following components in parts by weight: 35 parts of granite, 18 parts of high-silicon alumina, 0.53 parts of water reducing agent, and 10 parts of hollow glass microspheres. 39 parts of mullite, 18 parts of lead oxide ceramic particles, 5 parts of binder and 7 parts of proppant.

[0055] The water reducer is a polycarboxylate water reducer.

[0056] The proppant is prepared from 90 parts of bauxite powder, 2 parts of zeolite powder, 6 parts of titanium concentrate powder, 11 parts of diatomite and 5 parts of calcium oxide.

[0057] The preparation method of the proppant is as follows:

[0058] Step (1): Mix bauxite powder, zeolite powder, titanium concentrate powder, diatomaceous earth and calcium oxide in proportion, and stir evenly;

[0059] Step (2): Place the raw material mixture in a granulator to granulate and dry to obtain semi-finished balls;...

Abstract

The invention belongs to the technical field of processing of road plates, and provides wear-resisting pavement bricks and a preparation method. The wear-resisting pavement bricks are prepared from the following components: granite, cement with high silicon and aluminum contents, a water reducing agent, hollow glass micro beads, mullite, lead oxide ceramic particles, an adhesive and a supporting agent. The wear-resisting pavement bricks prepared from the granite serving as a material are attractive in surface, resistant to wear and antiskid; during use, stress on the wear-resisting pavement bricks is uniform, and corners of the brisk are difficult to crush. The production process of the wear-resisting pavement bricks is simple, and the production cost is low; the prepared pavement brocks are high in quality and good in flying dust adsorption effect.

Description

technical field [0001] The invention belongs to the technical field of road plate processing, and in particular relates to a wear-resistant pavement brick and a preparation method thereof. Background technique [0002] Existing pavement bricks are made of concrete pavement bricks with shapes such as triangles, squares, and regular hexagons through mixing, roasting or other molding processes with cement and aggregates as the main raw materials. Concrete pavement bricks are mainly used for laying concrete pavements such as urban roads, sidewalks, and urban squares, as well as blocks and slabs for ground engineering. But there is following problem in above-mentioned concrete pavement brick: [0003] (1) The wear resistance is not good, and the damage rate of its surface is very high under the wear and tear of automobiles and other vehicles; [0004] (2) The strength is not high, and the corners will be broken under the heavy pressure of vehicles such as cars; [0005] (3) Po...
