Problems solved by technology

Landfilling and incineration will not only produce dioxins, causing harmful substances and CO2 greenhouse gases to cause secondary pollution, but also high processing costs. For example, it costs US$110-120 to dispose of one ton of polymer material waste in the United States

Abstract

The invention provides a synthetic resin composition which consists of the following components in percentage by weight: 35 percent of component A and 65 percent of component B, wherein the component A is formed by polymerizing the following monomers in parts by weight: 20 parts of polyethylene, 20 parts of polypropylene, 15 parts of polyester, 8 parts of nylon, 10 parts of phthalic anhydride and 4 parts of pentaerythritol; and the component B is prepared from the following raw materials in parts by weight: 20 parts of pine tar, 8 parts of naphthenic oil, 10 parts of coumarone indene resin, 5 parts of 420 resin and 57 parts of rubber powder. In the resin composition, high molecular material waste can be effectively utilized and changed into things of value, and environmental pollution can be reduced. The invention also provides a preparation method and application of the resin composition.

Description

technical field [0001] The invention relates to a synthetic resin, its preparation method and application. Background technique [0002] Energy is the material basis for human survival and social development. All our daily consumer goods, our industrial and mining enterprises, transportation construction, and all our activities need energy, and energy is closely related to people's lives. The total energy consumption and the growth rate of energy consumption are directly proportional to the gross national economic product and the growth rate of the national economic product. It is precisely because of energy and its extensive use that it has promoted the great prosperity of the world economy and created an unprecedented material civilization in human history. [0003] But on the other hand, with the increase of the world's population and the rapid development of the economy, energy consumption continues to increase, and global environmental problems such as climate warming...
