Degradable plastic

Abstract

The invention provides a degradable plastic which is composed of, by weight, 30 to 70 parts of synthetic resins, 50 to 70 parts of plant fiber starch, 1 to 5 parts of photo-sensitizer and 5 to 20 parts of additives. The synthetic resins are selected from the combination of propene polymer (PP) resins and polylactic acids; the plant fiber starch is selected from garden wastes, in particular to leaves, weeds, limbs and the like; the additives include plasticizers, lubricants and heat stabilizers; the plasticizers are selected from one of tributyl citrate, mineral oil, acetic acid tributyl ester, urea and formamide; the lubricants are magnesium stearate; and the heat stabilizers are triphenyl phosphate. The degradable plastic has the advantages of biodegradation and light degradation, and the degradation is thorough; the starch is selected from the plant fiber starch, and the garden wastes are used, accordingly, both environmental problems are solved, and the cost of the degradation plastic is reduced; and components are simple, the cost is low, and the plastic is easy to produce.

Description

technical field [0001] The invention relates to a degradable plastic. Background technique [0002] Plastic is a common and durable material, but the pollution caused by plastic is also terrible. White pollution has caused irreversible damage to the environment. Therefore, degradable plastic products have always been a hot spot in research and development. Various new products emerge in endlessly. The earliest It is a photosensitive degradable material. The latest research and development hotspot is starch-based degradable plastics, that is, biodegradable plastics. However, today's degradable plastics may not be completely degradable. Degradable plastics cannot be degraded when they are buried in the soil, and the degradable polymer materials used to make degradable plastics are polycaprolactone (PCL), polylactic acid (PLA), polybutylene succinate ( PBS), the price is relatively expensive, how to use existing materials, especially waste materials, to produce a degradable pl...

Problems solved by technology

[0002]Plastic is a common and durable material, but the pollution caused by plastic is also terrible, white pollution has caused irreversible damage to the environment, so now biodegradable plastic Products have always been the hot spot of current research and development. Various new products emerge in endlessly. The earliest is photosensitive degradable materials. The latest research and development hotspot is starch-based degradable plastics, that is, biodegradable plastics. Plastics are difficult to degrade in some special areas such as drought or lack of soil, and photodegradable plastics cannot be degraded when buried in soil, and the degradable polymer material used to make degradable plastics is polycaprolactone (PCL), Polylactic acid (PLA) and polybutylene succinate (PBS) are relatively expensive. How to use existing materials, especially waste materials, to produce a degradable plastic can greatly reduce costs and reduce environmental pollution
