Problems solved by technology

[0002] The disposable raincoats prepared by the prior art are generally made of plastic, and are widely used in playgrounds, water sports, open-air courts, mountaineering tours, etc., and will be discarded after one-time use, causing white pollution. Although there are environmentally friendly raincoats produced in the prior art, materials with certain degradation properties are produced to avoid environmental pollution after they are discarded, but the environmental protection raincoats prepared by the prior art have general degradation properties and a long degradation time, which cannot meet the needs of the market. needs

Abstract

The invention discloses a degradable plastic film raincoat, and relates to the technical field of new materials. The raincoat is prepared from the following components: polyvinyl chloride resin, silicon-doped starch, phenolic resin, dilauryl thiodipropionate, trioctyl acetylcitrate, dodecyl polyglucoside, aluminum borate whisker, polycaprolactone, inorganic filler, a plasticizer and a dispersant.The added silicon-doped starch cooperates with nano diatomite modified phenolic resin, biodegradability of the environment-friendly film raincoat can be significantly improved, the same technical effect cannot be achieved by adopting unmodified starch or starch modified with other modification methods. Meanwhile, different types of starch also have different influences on biodegradability of the prepared film raincoat, and cassava starch is better than soybean starch in improvement of biodegradability of the plastic film raincoat.
