Environmental-friendly plastic additive and preparation method thereof

Abstract

The invention provides an environmental-friendly plastic additive which contains 1) low-density polyethylene, 2) nano-calcium carbonate, 3) sarin, 4) high-density polyethylene, 5) lubricant, 6) modified starch, 7) low-temperature thermal oxidant, 8) antistatic agent, 9) microorganism preparation, 10) polypropylene and 11) glycerol or propanediol. The invention also provides a preparation method of the environmental-friendly plastic additive and environmental-friendly plastics containing the additive. The plastic products containing the environmental-friendly plastic additive emit toxic gas with low concentration when being burnt so as not to cause air pollution, and can be decomposed by biological degradation after being buried for one year. Furthermore, the environmental-friendly plastic additive can be formed by jetting or extruding technology according to the actual need, and has simple manufacturing technique and strong practicability.

Description

technical field [0001] The invention relates to an environment-friendly plastic additive and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] As we all know, with the rapid development of the petrochemical industry after the middle of the 20th century, plastic materials have become the most important materials in people's daily life, such as plastic bags, plastic cups, shells of most home appliances, shoe materials, tableware, raincoats, agricultural products, etc. Films, packaging films, containers, stationery, leisure products, household products, etc. are all plastic products, so plastic materials are inseparable from people's daily life, but the biggest disadvantage of plastic materials lies in their waste disposal. Its characteristics of not being melted for thousands of years will greatly reduce the service life of the landfill; if incineration is used, the plastic products will produce dioxin, HCN, HF, CO, SO 2 ...

[0002] As we all know, with the rapid development of the petrochemical industry after the middle of the 20th century, plastic materials have become the most important materials in people's daily life, such as plastic bags, plastic cups, shells of most home appliances, shoe materials, tableware, raincoats, agricultural products, etc. Films, packaging films, containers, stationery, leisure products, household products, etc. are all plastic products, so plastic materials are inseparable from people's daily life, but the biggest disadvantage of plastic materials lies in their waste disposal. Its characteristics of not being melted for thousands of years will greatly reduce the service life of the landfill; if incineration is used, the plastic products will produce dioxin, HCN, HF, CO, SO 2 Toxic gases, such as toxic gases, will not only deteriorate the air quality around the incinerator or lead to the greenhouse effect, but there is also evidence that it may cause serious human health problems such as miscarriage of pregnant women and lung cancer; in recent years, air pollution caused by incinerators has caused Many serious protests have highlighted the difficulties and crises of plastic waste disposal, which urgently need to be resolved
