Problems solved by technology

[0003] Marble glue is mainly composed of unsaturated polyester, accelerator, initiator, polymerization inhibitor, light stabilizer, filler, etc. It needs to add a small amount of curing agent when using it. It has the advantages of fast curing speed, simple operation, and easy grinding. But on the other hand, marble glue also has disadvantages such as low strength, easy to become brittle, and easy to crack when the temperature difference is large. In order to reduce the influence of these factors on marble glue, active heavy calcium fillers are generally used in the prior art, but cloud The problem of poor toughness of stone glue

preparation example Construction

[0027] The invention provides a preparation method of a special filler for marble glue, comprising the following steps:

[0028] The calcium carbonate ore is mixed with sodium acrylate and then ground to obtain a first powder; the particle size of the first powder is 4-6 μm;

[0029] The calcium carbonate ore is mixed with sodium acrylate and then ball-milled to obtain a second powder; the particle size of the second powder is 1.2-2.5 μm;

[0030] The wollastonite is pulverized to obtain wollastonite powder;

[0031] Mixing the first powder, titanate and stearic acid for first modification to obtain a first modified powder;

[0032] Mixing the wollastonite powder and titanate for a second modification to obtain a second modified powder;

[0033] The second powder, the first modified powder and the second modified powder are mixed to obtain the special filler for marble glue.

[0034] In the present invention, unless otherwise specified, the raw materials used are all commer...

Embodiment 1

[0071] The calcium carbonate ore is washed and crushed in multiple stages to obtain calcium carbonate particles with a size of 5-10 mm. The obtained particles are ground by grinding or ball mill, adding 2wt‰ sodium acrylate as a grinding aid, and by controlling the rotating speed and classifying the classifier, the obtained Calcium carbonate powders with an average particle size of 5μm and 2μm were modified by a high-speed disperser by adding 3wt‰ titanate and 8wt‰ stearic acid to calcium carbonate with an average particle size of 5μm. The high-quality wollastonite ore is cleaned and multi-stage crushed to obtain wollastonite particles with a size of 5-10 mm. The wollastonite particles are ground by a ring roller mill, and acicular silicon with a crystal length of 20 μm is obtained by controlling the rotation speed and classification. The obtained acicular wollastonite was added to 5wt‰ titanate and modified by a high-speed disperser. The modified 5μm calcium carbonate, 2μm ca...

Abstract

The invention provides a special filler for marble glue and a preparation method thereof, and belongs to the technical field of fine chemical engineering. Mixing calcium carbonate ore with sodium acrylate, and grinding to obtain first powder; the particle size of the first powder is 4-6 [mu] m; mixing calcium carbonate ore with sodium acrylate, and performing ball milling to obtain second powder; the particle size of the second powder is 1.2 to 2.5 [mu] m; the preparation method comprises the following steps: crushing wollastonite to obtain wollastonite powder; mixing the first powder, titanate and stearic acid for first modification to obtain first modified powder; mixing the wollastonite powder with titanate, and carrying out second modification to obtain second modified powder; and mixing the second powder, the first modified powder and the second modified powder to obtain the special filler for marble glue. By controlling the particle size of the powder, the filler is more compact during filling, and the oil absorption value of the filler is reduced, so that the plasticizing effect during colloid curing is improved, and the toughness is improved.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a special filler for marble glue and a preparation method thereof. Background technique [0002] Since ancient times, stone has been loved by people as a building and decorative material. From the Great Wall of China to the stone lions in town houses, from the Leaning Tower of Pisa to Notre Dame de Paris, people can see the application of stone. However, natural stone is being mined and processed. During the process, stone fractures and cracks are often encountered, which requires the use of marble glue to repair the stone to make it complete and beautiful without affecting the use, so as to avoid unnecessary losses. [0003] Marble glue is mainly composed of unsaturated polyester, accelerator, initiator, polymerization inhibitor, light stabilizer, filler, etc. It needs to add a small amount of curing agent when using it. It has the advantages of fast curing speed, simple ...
