Problems solved by technology

After polishing with abrasives such as melamine resin grinding blocks and bitter soil abrasives, because the material of the abrasives is too hard, the contact point of the polishing is too sharp, and the print of the grinding head is obvious after polishing. The soft bristle wheel can be waxed to fill and flatten the grinding mark to have a more beautiful effect, but if the wax is filled too little, the grinding head mark cannot be covered and the appearance will be poor. If the wax is too much, the gloss is too high and the matte effect will not be achieved.
If the hardness of abrasive tools such as melamine resin abrasive blocks and bitter soil abrasive tools is lowered to solve the problem of obvious grinding head printing, the abrasive tools are easy to fall off due to insufficient toughness of the bonding material and are not wear-resistant.
Use abrasive tools such as grinding brushes, hair brushes, and sponge grinding blocks. The structure of such abrasive tools is porous, and the abrasive jumps too much, but the smoothing effect is poor, and the unevenness is too obvious; if the structure of this type of abrasive tools is looser, then Abrasives have weak grinding force, greater abrasive beating, and uneven polished brick surfaces; if the grinding brush and brush structure are made very dense and the strength is too high, problems such as scratches and scratches are prone to occur. And the sponge grinding block is made relatively hard, which is easy to produce agglomeration of abrasive grains and produce grinding marks or grinding head prints.
[0005] In recent years, there has been a demand for polishing matt or soft tiles in the market, and various abrasive tools are used in the polishing process of matt tiles or soft tiles, but the polishing effect is not ideal, the quality is poor, and the pass rate is low , adversely affect the marketing of matte or soft light bricks

preparation example Construction

[0038] When a two-component silicone resin or two-component polyurethane resin is prepared, the preparation method of the abrasive contains includes the following steps:

[0039] A. Depending on the function, divide the elastic resin into two copies;

[0040] B. The first elastic resin is mixed with abrasives, and the filler is mixed, and the first mixture is obtained;

[0041] C. A second mixture is mixed with a wax, a functional auxiliary agent, and a first mixture to obtain a second mixture;

[0042] D, mount the second mixture into the mold and cooled after cure.

[0043] The elastic resin is divided into two components depending on the function, and there is a different role in the preparation process, and the addition of other impurities has good performance in avoiding the addition of other impurities.

[0044] When a reactant using a polyurethane resin is used as a material to prepare a raw material, the preparation method of the abrasive contains includes the following st...

Embodiment 1

[0050] The elastic resin binding agent in the abrasive tool in Example 1 selected a fed-form silicone rubber.

[0051] The abrasive tool in Example 1 was prepared by the following preparation method: 20 parts of the silicone rubber according to 20 parts of the liquid silicone rubber, 10 parts of 180 # diamond sand, 40 parts of 180 # green silicon carbide, 4 parts of chromium oxide poured into the stirring In the cylinder, stirring at a rate of 1000 rpm for 10 minutes, then 20 parts of the liquid silicone rubber curing agent B, 4.5 parts of liquid paraffin, 1 coupling agent, 0.5 parts of catalyst, and stirred by 1500 rpm / min. After the uniform slurry is formed in 5 minutes, it is poured into a mold for a long 13 cm, a deep 1.5cm, a width of 5.5 cm. After curing, after curing, then in addition to the 100 degree oven for 5 hours, and then demolded after cooling. Abrasive.

Embodiment 2

[0053] Example 2 The elastic resin binding agent in the abrasive was used to use the addition silicone rubber.

[0054] The abrasions in Example 2 were prepared by the following preparation methods: 10 parts of the liquid silicone rubber A, 180 # diamond sand 10 parts, 180 # green carbonation, 4 parts of chromium oxide poured into the stirring cylinder, at 1000 The rotation / minute is stirred for 10 minutes, then add 25 parts of the liquid silicone rubber curing agent B, 4.5 parts of liquid paraffin, 1 couparent agent, 0.5 parts of the catalyst, and stir for 1500 rpm for 5 minutes to form uniform. After the slurry, poured into a die length 13 cm, deep 1.5cm, width of 5.5 cm, scraping the flat, standing for 1 hour, then placed in a 100 degree oven to curing for 5 hours, and then demolded after cooling to obtain the abrasive.

Abstract

The invention provides a ceramic polishing grinding tool and a preparation method thereof. The grinding tool comprises, by weight, 25%-50% of elastic resin, 30%-70% of grinding materials, 0%-25% of filling materials, 0%-10% of wax and 0%-5% of functional auxiliary agents. The elasticity of the grinding tool is larger than 120%, the hardness ranges from 75 A to 95 A, the adhesive strength is larger than 6 MPa, and the resistance temperature is larger than 150 DEG C. The elastic resin can be organic silicon rubber or polyurethane resin. The polyurethane resin can adopt an elastic polyurethane rubber finished product or adopts polyester polyol or polyether polyol to respectively react with polyisocyanate to generate elastic micro-foaming polyurethane resin. The elastic resin is adopted as a binding agent material, and after the elastic resin and the grinding material are combined to form a composite material, the composite material has good elasticity and toughness, strength and durability and is high in grinding force on ceramic, and the problems of grinding patterns, scratches and the like appearing during ceramic polishing are effectively solved.

Description

Technical field [0001] The present invention relates to the field of grinding tools, in particular to a ceramic polishing abrasive tool and a preparation method thereof. Background technique [0002] Ceramic tiles are an important part of building materials. As people's production level, the quality of life is improved, the quality requirements of ceramic tiles have also increased. Ceramics After sintered, the brick surface will have different degrees of sand, unevenness, or even grooves, affect the appearance quality of ceramic tiles. In order to improve the quality of the ceramic tile, the ceramic tile is needed to polish the ceramic tile. Ceramic tiles have been polished after the abrasive is polished, and the surface will become more flat, beautiful, antifouling, easy to clean. The polished tiles can be divided into high light tiles, antique bricks, matte bricks and soft bricks depending on the polishing effect, and the gloss of high gloss is basically more than 80 degrees, l...
