Special filler for modified light calcium carbonate plastic and preparation method for special filler

Abstract

The invention discloses a special filler for modified light calcium carbonate plastic. The special filler is prepared from the following raw materials in parts by weight: 1-2 parts of perfluoroalkyl ethyl phosphite ester, 4-6 parts of light magnesium oxide powder, 2-3 parts of polyethylene glycol 400, 3-4 parts of nano carbon fibers, 1-1.5 parts of isocyanate, 1-2 parts of alkyd resin, 1-2 parts of glycol distearate, 2-3 parts of nano iron-ore slag, 200-220 parts of light calcium carbonate, 5-9 parts of auxiliaries and 20-30 parts of water. The special filler adopted by the invention adopts the perfluoroalkyl ethyl phosphite ester, the isocyanate, the alkyd resin and the glycol distearate, so that the surface energy among particles is reduced, the compatibility and the dispersion of the plastic are strengthened, the processing mobility is improved, and the impact strength, the rigidity, the heat resistance and the dimension stability of products are improved; by adding the nano carbon fibers and the nano iron-ore slag, the tensile strength, the wear resistance and the antistatic performances of the plastic can be improved.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a special filler for modified light calcium carbonate plastics and a preparation method thereof. Background technique [0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. In recent years, my country's economy has achieved sustained and stable growth. Industries such as home appliances, automobiles, mobile phones, PCs, and medical equipment have benefited from a favorable external environment and have also achieved rapid development. The development of downstream industries has further stimulated the demand for plastics. Compared with the advanced level, there is still a certain gap in my country's synthetic resin industry. The quantity of some domestic high-end products cannot meet the market demand, and the quality needs to be improved and improved. At present, the performance def...

In recent years, my country's economy has achieved sustained and stable growth. Industries such as home appliances, automobiles, mobile phones, PCs, and medical equipment have benefited from a favorable external environment and have also achieved rapid development. The development of downstream industries has further stimulated the demand for plastics. Compared with the advanced level, there is still a certain gap in my country's synthetic resin industry. The quantity of some domestic high-end products cannot meet the market demand, and the quality needs to be improved and improved.

At present, the performance defects of plastics are manifested in wear resistance, aging resistance, oil resistance, high temperature resistance, strength, chemical stability, bending strength, creep performance, etc., which need continuous improvement
