Heat-resistant filler for plastics and preparation method of heat-resistant filler

Abstract

The invention discloses a heat-resistant filler for plastics. The filler is prepared from the following raw materials in parts by weight: 1-2 parts of magnesium stearate, 3-4 parts of zirconia ceramic microbeads, 0.1-0.2 part of sodium dodecyl benzene sulfonate, 2-3 parts of pure acrylic emulsion, 1-2 parts of hexafluoro-acetylacetone, 0.2-0.3 part of China wood oil, 0.2-0.3 part of carnauba wax, 2-3 parts of nanometer iron-ore slag, 200-220 parts of light calcium carbonate, 5-9 parts of aids and 20-30 parts of water. According to the filler, due to addition of the zirconia ceramic microbeads, the heat resistance of the plastic can be improved; due to addition of the nanometer iron-ore slag, the wear resistance and strength of the plastics can be improved; and moreover, calcium carbonate is subjected to surface modification by using pure acrylic emulsion, hexafluoro-acetylacetone, China wood oil and carnauba wax, so that calcium carbonate is high in lipophilicity, the compatibility of calcium carbonate with the plastics is increased, and the strength of the plastics can be improved.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a heat-resistant filler for 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 defects of plastics are manif...

Problems solved by technology

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
