Abstract

The invention relates to the technical field of recycling of polypropylene regenerated materials and particularly relates to a regenerated polypropylene environment-friendly modified material and a preparation method thereof. The regenerated polypropylene environment-friendly modified material comprises the following substances in parts by weight: 100 parts of polypropylene recycled materials, 10-15 parts of glass fibers, 30-40 parts of nitrogen-phosphor compounded expansion flame retardants, 0.3-0.8 part of a synergistic flame retardant, 4-10 parts of an anti-impact modifier, 1-2 parts of an antioxidant, and 0.1-0.5 part of a coupling agent, wherein the synergistic flame retardant is silicon dioxide, the anti-impact modifier is recycled rubber material, the coupling agent is a titanate coupling agent. According to the regenerated polypropylene environment-friendly modified material disclosed by the invention, the regenerated polypropylene is low in toxicity, low in smoke, free of melt drops and high in oxygen index, the material is high in mechanical performance and low in preparation cost, capable of saving the material cost, environmentally friendly, economical and efficient. The polypropylene recycled material obtained by the preparation method is high in polypropylene purity, less in impurity and simple in preparation process, and industrialization is easy to realize.

Description

technical field [0001] The invention relates to the technical field of recycling polypropylene recycled materials, in particular to a recycled polypropylene 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 oi...
