Embodiment 1

[0014] A modified heavy calcium carbonate for blinds, prepared by the following parts by weight of raw materials:

[0015] 100 parts of heavy calcium carbonate, 0.7 parts by weight of sodium cetyl sulfate, 1 part by weight of sodium stearate, and 1 part by weight of ricinoleic acid.

[0016] The specific preparation method is as follows: adding sodium cetyl sulfate, sodium stearate, and ricinoleic acid dropwise with heavy calcium carbonate into a dry mixer, and mixing at a high speed at 70-80°C for 25 minutes to obtain.

Embodiment 2

[0018] A modified heavy calcium carbonate for blinds, prepared by the following parts by weight of raw materials:

[0019] 100 parts of heavy calcium carbonate, 1 part by weight of sodium cetyl sulfate, 0.5 parts by weight of sodium stearate, and 1.5 parts by weight of ricinoleic acid.

[0020] The specific preparation method is as follows: adding sodium cetyl sulfate, sodium stearate, and ricinoleic acid dropwise with heavy calcium carbonate into a dry mixer, and mixing at a high speed for 30 minutes at 70-80° C. to obtain.

Embodiment 3

[0022] A modified heavy calcium carbonate for blinds, prepared by the following parts by weight of raw materials:

[0023] 100 parts of heavy calcium carbonate, 0.5 parts by weight of sodium cetyl sulfate, 0.7 parts by weight of sodium stearate, and 1.3 parts by weight of ricinoleic acid.

[0024] The specific preparation method is as follows: adding sodium cetyl sulfate, sodium stearate, and ricinoleic acid dropwise with heavy calcium carbonate into a dry mixer, and mixing at a high speed at 70-80° C. for 20 minutes to obtain.

[0025] In this example, through the combination of 16-18 alkyl salt and 18 carbene compound, ricinoleic acid can form a better coating effect on the surface of heavy calcium carbonate through its carboxylic acid group and ethylenic bond, forming a core-shell structure, hard Sodium fatty acid and sodium cetyl sulfate form a long-chain structure on the surface of the shell layer to form a three-layer sphere structure, which makes the distance between the parti...

Abstract

The invention relates to the field of calcium carbonate, and discloses modified heavy calcium carbonate used for a louver blade. The modified heavy calcium carbonate is prepared from the following rawmaterials in parts by weight: 100 parts of heavy calcium carbonate, 0.5 to 1 part of sodium cetyl sulfate, 0.5 to 1 part of sodium stearate and 1 to 1.5 parts of ricinoleic acid. The objective of theinvention is to provide low-agglomeration modified heavy calcium carbonate used for the louver blade.

Description

Technical field [0001] The invention relates to the field of calcium carbonate, in particular to a modified heavy calcium carbonate for blinds. Background technique [0002] Heavy calcium carbonate is ground from natural carbonate minerals such as calcite, marble and limestone. It is a commonly used powdery inorganic filler, with high chemical purity, high inertness, difficult chemical reaction, good thermal stability, will not decompose below 400 ℃, high whiteness, low oil absorption, low refractive index, soft, dry, No crystal water, low hardness, low abrasion value, non-toxic, odorless, odorless, and good dispersibility. The shape of heavy calcium carbonate is irregular, and its particle size varies greatly, and the particles have certain edges and corners, the surface is rough, the particle size distribution is wider, and the particle size is larger. The average particle size is generally 1-10μm. This also brings some shortcomings of heavy calcium carbonate in the applicati...
