Abstract

The invention relates to the technical field of recycling of HIPS regenerated materials, and particularly relates to a regenerated HIPS environmental-friendly modified material and a preparation method thereof. The regenerated HIPS environmental-friendly modified material comprises the following substances in parts by weight: 100 parts of HIPS recovered materials, 3-6 parts of toughening agents, 15-20 parts of flame retardants, 1-2 parts of flame-retardant synergists, 10-12 parts of anti-impact modifying agents, 1-2 parts of antioxidants, 1-4 parts of coupling agents, 2-5 parts of lubricating agents and 2-5 parts of stabilizing agents, wherein the flame retardants are formed by mixing a compound flame retardant of ammonium polyphosphate, magnesium hydroxide and boric acid with montmorillonite-hexadecyl trimethyl ammonium bromide. The regenerated HIPS has the advantages of low toxicity, low smoke and no corrosion and is favorable to the flame retardance of HIPS. The regenerated HIPS environmental-friendly modified material disclosed by the invention is high in mechanical property, low in cost, capable of effectively saving the material cost, environmental-friendly, economic and effective. The preparation method disclosed by the invention has the advantages of high HIPS purity and few impurities of an obtained HIPS recovered material, simple preparation process and easiness for industrialization realization.

Description

technical field [0001] The invention relates to the technical field of recycling HIPS recycled materials, in particular to a recycled HIPS environmentally friendly modified material and a preparation method thereof. Background technique [0002] Today, China has entered the peak period of discarding household appliances, and more than 30 million discarded household appliances will be produced every year. Such a huge waste of household appliances will inevitably produce a large amount of waste plastics. There are three ways to recycle waste plastics: sanitary landfill, incineration for heat, and resource recycling. Among them, landfill and incineration are likely to cause waste of resources and secondary pollution, which is contrary to the theme of the era of green environmental protection. [0003] Nowadays, the recycling of waste plastics mainly adopts the method of recycling, mainly including direct regeneration, modified regeneration, gasification and oil treatment. Howe...
