Abstract

The invention discloses wearable flame-retardant light calcium carbonate packing, which is prepared from the following raw materials in parts by weight: 2-3 parts of talcum powder, 0.4-0.6 part of molybdenum disulfide, 1-2 parts of copper oxide, 2-3 parts of lanthanum oxide, 0.4-0.6 part of tall oil, 1-1.5 parts of calcium stearate, 3-5 parts of decabromodiphenyl ether, 0.4-0.6 part of polyoxyethylated castor oil, 2-3 parts of methacrylate, 0.1-0.2 part of potassium peroxodisulfate, 2-4 parts of dibutyltin dilaurate, 3-4 parts of polyisobutene, 2.2-2.5 parts of stearate, 1.2-1.4 parts of silicone oil containing hydrogen, 80-85 parts of light calcium carbonate, 13-16 parts of an assistant and 120-140 parts of water. The light calcium carbonate surface of the packing is coated by an organic matter layer, so that the packing is firmly combined, the interface bonding with the PVC is enhanced, the overall performance of the material is improved, the flame-retardant property of the PVC is increased by adding of the decabromodiphenyl ether, and the dispersity and the abrasive resistance are improved.

Description

technical field [0001] The invention belongs to the field of plastic processing, in particular to a wear-resistant and flame-retardant 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 proces...
