Problems solved by technology

However, even with such surface-treated calcium carbonate, it is difficult to impart high viscosity and high thixotropy
[0009] In addition, when the surface of calcium carbonate is generally treated with fatty acid, the viscosity and physical properties of the pasty sol-curable resin composition blended with the calcium carbonate are improved. However, the use of fatty acid results in the disadvantage of poor mechanical properties and adhesive properties of the cured product.

Embodiment 1）

[0100] In 2kg BET specific surface area is 22.2m 2 / g of synthetic calcium carbonate, water adjusted to 60°C was added so that the solid content was 10% by weight, and a calcium carbonate slurry was prepared using a stirring type disperser. While stirring this slurry with a disperser, add 54g mixed fatty acid sodium salts (in acid conversion, 19.9g palmitic acid, 27.9 g stearic acid), after stirring for 5 minutes, press and dehydrate.

[0101] After drying the obtained dehydrated cake, about 2 kg of surface-treated calcium carbonate was obtained by powdering.

Embodiment 2）

[0103] Use BET specific surface area of ​​17.9m 2 / g of synthetic calcium carbonate, add 40g of mixed fatty acid sodium salts (in terms of acid conversion, 14.7g of palmitic acid, 22.3g of stearic acid) mixed with 16g of sodium palmitate and 24g of sodium stearate, in addition, with Above-mentioned embodiment 1 operates similarly, obtains surface-treated calcium carbonate.

Embodiment 3）

[0105] Except adding 46 g of mixed fatty acid sodium salts mixed with 18.4 g of sodium palmitate and 27.6 g of sodium stearate (in terms of acid conversion, 16.9 g of palmitic acid and 25.6 g of stearic acid), the same operation was performed as in Example 1 above, Get surface treated calcium carbonate.

Abstract

Disclosed are: surface-treated calcium carbonate which can impart a high viscosity and high thixotropic properties to a paste-like resin composition when added to the composition and can impart good mechanical properties and good adhesion properties to a cured product of the paste-like resin composition; and a paste-like resin composition containing the surface-treated calcium carbonate. The surface-treated calcium carbonate is produced by treating the surface of calcium carbonate with a surface-treating agent comprising a sodium salt or a potassium salt of a fatty acid, is characterized in that the sum total of PW and SW (PW + SW) is 90 or more and the ratio of PW to SW (PW / SW) falls within the range from 0.30 to 1.1 inclusive (wherein PW represents the content (wt%) of the sodium salt or the potassium salt of palmitic acid in the surface-treating agent in terms of acid content; and SW represents the content (wt%) of the sodium salt or the potassium salt of stearic acid in the surface-treating agent in terms of acid content), and is also characterized in that SA2 falls within the range from 15 to 48 inclusive and the ratio of FA to SA2 (FA / SA2) falls within the range from 0.095 to 0.135 inclusive (wherein SA2 represents the BET specific surface area (m2 / g) of the surface-treated calcium carbonate; and FA represents the amount of the sodium salt or the potassium salt of the fatty acid to be used for the treatment in terms of acid content relative to 100 parts by weight of calcium carbonate).

Description

technical field [0001] The present invention relates to surface-treated calcium carbonate and a pasty resin composition containing the surface-treated calcium carbonate. Background technique [0002] In adhesives, sealing materials, etc., a paste-like sol is prepared, and the sol is used for coating, painting, construction, mixing, etc. When it is not possible to mix a large amount of filler in the pasty sol due to the physical properties and quality of the cured product, a filler such as fumed silica that can impart high viscosity to the sol with a small amount is used. [0003] However, fumed silica exhibits high thixotropy (thixotropy), and there is also a problem that the added amount differs by a small amount and the viscosity changes extremely. [0004] On the other hand, calcium carbonate is used as a filler in various polymer materials, such as plastics, rubber, inks, coatings, sealing materials, PVC sols, acrylate sols, and the like. Therefore, since high thixotro...
