Abstract

The invention belongs to the technical field of high-molecular material recovery, modification and processing, and relates to a modified plastic, and a preparation method and a use thereof. The modified plastic is prepared from the following components, by weight, 100 parts of a polyethylene resin, 80-140 parts of a waste plastic, 30-80 parts of a reinforced fiber, 60-140 parts of a combination filler, 8-16 parts of a light stabilizing agent, 11-20 parts of a compound antioxidant, 15-25 parts of a plasticizer, 50-80 parts of an inorganic compound flame retardant and 1.5-2.0 parts of a dispersant. The modified plastic provided by the invention has the advantages of high strength, good toughness, impact resistance, easy processing, long life, low cost, and good flame resistance. The method is simple and practical, and the modified plastic obtained through the method also has the advantages of waste plastic recycle, production cost reduction, and environmental protection, so the modified plastic is a novel agricultural greenhouse framework material.

Description

technical field [0001] The invention belongs to the field of polymer modification technology and processing technology, and relates to a modified plastic and its preparation method and application. Background technique [0002] With the rapid development of world economy and science and technology, the improvement of people's material living standards and the acceleration of urbanization, the output of urban solid waste has increased sharply. According to statistics, the current annual output of municipal solid waste in my country has exceeded 150 million tons, and is growing at a rate of 8% to 10% every year. About 2 / 3 of the cities in our country are surrounded by garbage. Waste plastics in urban life in my country account for about 4% to 10% of the total garbage, with an annual output of 5 to 6 million tons, and is growing at a rate of nearly 8% to 9% every year. [0003] At present, my country's municipal solid waste treatment technology is still dominated by sanitary ...
