Abstract

The invention discloses antibacterial and ozone-resistant modified calcium carbonate. Antibacterial and ozone-resistant modified calcium carbonate is prepared from the following raw materials in parts by weight: 0.5-0.7 part of cadmium stearate, 2-3 parts of glycerin, 1-2 parts of activated carbon, 0.4-0.6 part of lanthanium stearate, 2-3 parts of nano attapulgite, 1-1.5 parts of oxidized polyethlene wax, 3-4 parts of barium hydroxide, 2-3 parts of tetrabutyl titanate, 1-2 parts of disproportionated potassium abietate, 2-2.5 parts of eleostearic acid, 4-6 parts of chlorinated polyethylene, 0.8-1.1 parts of nano silver, 0.1-0.2 part of sodium hydroxide, 80-85 parts of light calcium carbonate, 13-16 parts of an auxiliary agent and 120-140 parts of water. According to antibacterial and ozone-resistant modified calcium carbonate disclosed by the invention, the nano silver is added into a filling material to ensure that PVC (polyvinyl chloride) has permanent antibacterial performance; chlorinated polyethylene is added to ensure that the weather resistance, ozone resistance, chemical medicine resistance and aging resistance of the PVC can be increased, and good oil resistance, flame-retardant performance and coloring performance can be provided; by virtue of surface treatment, calcium carbonate disclosed by the invention has good compatibility with PVC, and can be used for improving the mechanical performance of PVC.

Description

technical field [0001] The invention belongs to the field of plastic processing, in particular to an antibacterial and ozone-resistant modified calcium carbonate 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...
