Flame-retardant plastic packing and preparation method thereof

Abstract

The invention discloses a flame-retardant plastic packing, which is prepared from the following raw materials in parts by weight: 3-5 parts of superfine porous silicon dioxide, 2-3 parts of nanoscale antimony trioxide, 1-2 parts of epoxy octyl stearate, 0.4-0.6 part of ethylene glycol monostearate, 0.2-0.3 part of avocado oil, 0.3-0.4 part of tragacanth gum, 2-3 parts of nano-iron slag, 200-220 parts of lightweight calcium carbonate, 5-9 parts of auxiliaries and 20-30 parts of water. Nanoscale antimony trioxide is added in the filler, so that the flame-retardant property of plastics can be improved; calcium carbonate is modified by using epoxy ethylhexyl stearate, ethylene glycol monostearate, avocado oil and tragacanth gum, so that the lipophilicity of calcium carbonate can be improved, and the reinforcement effect is good; through the auxiliaries, the dispersity and self-lubrication property of the packing can be improved.

Description

technical field [0001] The invention belongs to the field of plastics, in particular to a flame-retardant plastic filler 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 manifeste...

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
