Abstract

The invention relates to an acrylate-modified calcium carbonate filler capable of improving machinability, which is characterized by being prepared from the following raw materials in parts by weight: 200 parts of nano calcium carbonate, 6-8 parts of 3-aminopropyltriethoxysilane, 20-25 parts of iron stearate, 10-12 parts of molybdenum disulfide, 6-8 parts of para-polyphenylene, 12-15 parts of sodium p-styrenesulfonate, 5-6 parts of poly(butylene succinate), 4-5 parts of sodium diisopropylnaphthalene sulfonate, 25-30 parts of methyl acrylate, 10-12 parts of ammonium persulfate, 35-45 parts of 2-morpholinoethyl methacrylate, 12-15 parts of titanium diisopropoxide bis(acetylacetonate), an appropriate amount of methanol and an appropriate amount of deionized water. The calcium carbonate filler provided by the invention has the advantages of fineness, uniformity, high whiteness, low wear rate, oleophobicity and good 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 capable of improving machinability 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 na...
