The present invention aims to solve the technical problem of the raise of the utilization rate of silicon carbide abrasives in the grinding block and thereby, to enhance the durability of the grinding block. Compared with an originally used grinding block, waste materials ground by machine grinding are greatly reduced. Thereby, industrial pollution is greatly reduced, which is favorable to environmental protection. Therefore, the present invention has the following technical proposals: firstly, the chemical components (weight percentage) of the sintered grinding block comprises 39 to 51 of abrasives, 3 to 8 of fluxing agents, 5 to 16 of filling materials, 24 to 37 of sintered binders, 1.8 to 4 of an additive (1), 2.2 to 5 of an additive (2) and a proper quantity of water; secondly, the components are mixed, are ball milled, are stirred uniformly, are put into a mould, are pressed and molded by a press and are sintered into the finished product by a furnace. Sintering temperature range is between 800 DEG C and 1250 DEG C, and sintering time range is between 9 hours and 14 hours. The sintered grinding block can be made into the shape of clockwise skewed teeth or other shapes.
Description
Technical field
The present invention relates to ceramic flat surface grinding tool technical field, the sintering grinding block that particularly a kind of ceramic board grinding is used.
Background technology
Existing application is to do glue crosslinking agent with magnesia, magnesium chloride in the abrading block of floor tile and stone material grinding-polishing, and the carbonization silica sand is done abrasive material, through the mixing pulping, and casting forming, natural air drying is deposited more than 15 days and could be used.This abrading block has the following disadvantages:
(1) the abrasive material carborundum sand that price is the most expensive, utilization rate is low, and this is because glue crosslinking agent is little to particle and adhesion surperficial comparatively slick and sly carborundum sand is not strong, abrading block is shaped and only depends on natural air drying, therefore its abrasive material breaks away from the abrading block water that is cooled easily and washes away, utilization rate less than 50%, and waste is greatly.
(2) the abrading block durability is low, and every abrading block was only just scrapped about 2 hours in the machine grinding time.Because abrading block service time is short, need frequently to change, wasted the time, water power, grinding machine often flogs a dead horse, and has increased working strength of workers again.
(3) abrasive material can not be formed firm integral body because employed glue connects mixture, abrading block is stressed in grinding process, under the effect of rotating speed, belt pressure, add the frictional force of adobe, caused the abrading block abrasive material fast mill take off.Calculate by 28 grinding machines, per hour directly abrasion are 84 kilograms of dry sand powder, add cooling water, then per hour are no less than 250 kilograms of mortars and discharge, and contaminated environment is brought serious environmental issue.
Summary of the invention
The technical problem to be solved in the present invention is: (1) improves the utilization rate of silicon carbide abrasive in abrading block, thereby improves the durability of abrading block; (2) waste material under the machine grinding is ground will reduce significantly than the abrading block of original employing, thereby has reduced industrial pollution widely, helps environmental protection.
