Abstract
The invention relates to a high-dispersibility modified calcium carbonate filler. The high-dispersibility modified calcium carbonate filler is prepared from the following raw materials in parts by weight: 3-4 parts of PVC (poly vinyl chloride) resin powder S-1300, 3-5 parts of nitrile buna rubber powder, 1-1.5 parts of sodium ethylene diamine tetracetate, 1-1.4 parts of shea butter, 0.4-0.5 part of boric acid, 3-5 parts of diatomite, 1-1.5 parts of sodium ethylene diamine tetracetate, 0.1-0.2 part of potassium aliphatate, 0.2-0.4 part of calcium resinate, 0.2-0.4 part of cobalt resinate, 80-85 parts of light calcium carbonate, 13-16 parts of auxiliary, a proper amount of water and a proper amount of 2-3% hydrochloric acid. The high-dispersibility modified calcium carbonate filler has the advantages that diatomite is added, and dispersibility of a modifying agent is improved, so that calcium carbonate is uniformly modified, and dispersibility is improved; shea butter is added, and permeability is good, so that surface of calcium carbonate is organized, and dispersibility is improved; PVC resin powder S-1300 and nitrile buna rubber powder are added, so that compatibility between the filler and PVC is improved; and the auxiliary is added, so that wettability of calcium carbonate in PVC can be improved, and defects of PVC are reduced.
Description
technical field [0001] The invention belongs to the field of plastic processing, in particular to a highly dispersible modified 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 polym...
