Problems solved by technology

[0003] Although the existing plastics have excellent performance, their degradation rate in the soil is not high, and they are easy to cause environmental pollution. At the same time, the existing injection molding equipment in the plastic injection molding process cannot meet the circular injection molding of multiple mold shells. At the same time, after injection molding, it is necessary to set up an independent cooling water mechanism to cool down the mold shell, and the cooling cost is high.

Abstract

The invention discloses s degradable environment-friendly plastic and a preparation method thereof. Polycaprolactone, polyvinyl chloride and polylactic acid are used as main raw materials, nano-silicon dioxide with an anti-ultraviolet effect, a UV531 anti-ultraviolet agent, epoxy resin with a light stabilizing effect, a flame retardant talcum powder, a plasticizer, a coupling agent titanate and afiller nano-calcium carbonate are added, so the prepared environment-friendly plastic has excellent toughness, rigidity, flame retardant property and antibacterial property; and the environment-friendly plastic does not contain halogen ions, and polylactic acid is biodegradable, so the environment-friendly plastic has biodegradability and strong air permeability, and is finally converted into CO2and H2O under the metabolic action of microorganisms in soil, and the 25-day degradation rate of the environment-friendly plastic is 99-99.2 according to GB / T20197-2006 determination.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, in particular to a degradable environmentally friendly plastic and a preparation method thereof. Background technique [0002] At present, plastic has become an indispensable synthetic material in people's life. With the continuous growth of plastic production, it brings convenience to people and also brings serious environmental pollution problems. Due to the characteristics of acid and alkali resistance, anti-oxidation, resistance to corrosion, and refractory degradation, plastics will not rot for a hundred years after being buried in the ground, and will produce a large amount of toxic gases when burned. Therefore, while studying the recycling technology of waste plastics, degradable plastics, as the most likely way to solve the problem of plastic waste, have become a research hotspot at home and abroad. [0003] Although the existing plastics have excellent performance, their de...
