Abstract

The invention discloses an anti-ageing modified light calcium carbonate filler which is prepared from the following raw materials in parts by weight: 2-3 parts of barium stearate, 2.3-3.5 parts of dioctyl phthalate, 2-3 parts of glyceryl stearate, 1-1.3 part of glycerol, 4-6 parts of superfine talcum powder, 0.4-0.7 part of sunflower seed extract, 0.4-0.6 part of cyanoethyl cellulose, 4-6 parts of zinc oxide, 1-2 parts of stearic acid, 0.3-0.5 part of potassium sulfate, 0.2-0.3 part of phosphoric acid, 2-2.5 parts of silica sol, 80-85 parts of light calcium carbonate, 13-16 parts of auxiliaries and 120-140 parts of water. The filler disclosed by the invention comprises the barium stearate and the superfine talcum powder, so that the self-lubrication is good, the dispersibility is good, agglomeration is not easy to occur and the PVC has less local defects; through adding the zinc oxide and the sunflower seed extract, the anti-ageing property of the PVC is increased; and through adding the dioctyl phthalate, the glyceryl stearate and the glycerol, the organic property of the calcium carbonate is increased and the compatibility with the PVC is good.

Description

technical field [0001] The invention belongs to the field of plastic processing, in particular to an anti-aging 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 polyme...
