Abstract

The invention discloses acrylic ester modified calcium carbonate packing with a good self-lubrication property. The acrylic ester modified calcium carbonate packing is characterized by being prepared from the following raw materials in parts by weight: 200 parts of nano calcium carbonate, 6-8 parts of octadecyl trimethyl ammonium chloride, 20-25 parts of vitric, 10-12 parts of decabromodiphenyl ethane, 6-8 parts of poly butylene tertephehalate, 12-15 parts of sodium styrene sulfonate, 5-6 parts of sodium di(2-ethyl-hexyl)sulfosuccinate, 4-5 parts of sorbitan fatty acid ester, 25-30 parts of crylic acid, 10-12 parts of ammonium persulfate, 35-45 parts of hydroxyethyl methylacrylate, 12-15 parts of diacetone-acryloamide, a proper amount of methanol and a proper amount of deionized water. The acrylic ester modified calcium carbonate packing disclosed by the invention has the advantages of being fine, uniform, high in whiteness, low in abrasion rate, oleophobic, good in optical property and the like.

Description

technical field [0001] The invention relates to a calcium carbonate filler, in particular to an acrylate-modified calcium carbonate filler with good self-lubricating properties and a preparation method thereof. Background technique [0002] Nano-calcium carbonate is a new type of inorganic filler. Due to its various outstanding characteristics, it is gradually replacing traditional calcium carbonate in the field of material addition. It is called an important industrial raw material and has been widely used in plastics, rubber, coatings and papermaking. and other fields. However, the surface of nano-calcium carbonate is hydrophilic and oleophobic, has strong polarity, is difficult to combine with organic polymers, and has poor compatibility with commonly used organic raw materials, so it is difficult to uniformly disperse in the polymer matrix. Therefore, how to increase the surface affinity of nano-calcium carbonate and common polymer collectives, improve the dispersion of...
