Abstract

The invention discloses self-lubricating modified light calcium carbonate filler which is prepared from the following raw materials in parts by weight: 2-3 parts of zinc stearate, 3-5 parts of polyoxyethylene, 0.5-0.7 part of inulin, 2-3 parts of graphite fluoride, 0.2-0.3 part of sodium potassium tartrate tetrahydrate, 0.1-0.2 part of sodium lignin sulfonate, 1-1.5 parts of nano crystalline cellulose, 0.5-0.8 part of benzotriazole, 1-1.5 parts of sulfo-diethylene glycol, 2-3 parts of butyl acrylate, 1-2 parts of a crylic acid, 0.4-0.5 part of poly(oxy-1,2-ethanediyl), 2-3 parts of nano zinc oxide, 0.1-0.2 part of ammonium persulfate, 80-85 parts of light calcium carbonate, 13-16 parts of aids and 120-140 parts of water. The filler disclosed by the invention is good in dispersibility; a modifier can form a uniform and integral coating layer on the surface of the nano calcium carbonate, so that the water delivery property of the surface of the calcium carbonate is good, and the strength and wear resistance of the surface of the calcium carbonate are increased; and due to addition of nano zinc oxide, the age resistance of PVC is increased.

Description

technical field [0001] The invention belongs to the field of plastic processing, in particular to a self-lubricating modified light calcium carbonate filler and a preparation method thereof. Background technique [0002] Calcium carbonate is a widely used inorganic filler, which can be applied to plastic products, rubber products, coatings, adhesives, etc., especially light calcium carbonate, which has a great effect on the dimensional stability of PVC plastic products, and can Increasing the hardness of the product can also improve the surface gloss and surface smoothness of the product. Adding calcium carbonate to general PVC plastic products can improve the heat resistance. Since the whiteness of calcium carbonate is above 90%, it can also replace expensive white pigments and play a certain role in whitening. However, calcium carbonate has strong hydrophilicity. If the surface is not modified, the compatibility with the polymer matrix is ​​poor during the processing of p...
