Abstract

The invention discloses completely degraded starch / PVA (Polyvinyl Alcohol) plastic fishing bait and a processing method thereof, and relates to the technical field of completely degraded plastic processing. The completely degraded starch / PVA plastic fishing bait is made of the following raw materials in parts by weight: 25-30 parts of plant starch, 15-20 parts of polyvinyl alcohol, 3-5 parts of coal ash, 3-5 parts of a biodegradable additive, 2-3 parts of an environmental-friendly plasticizer, 1-2 parts of a zeolite powder, 1-2 parts of anionic polyacrylamide, 0.5-1 part of a ceramic micro powder, 0.5-1 part of a cross-linking agent, 0.05-0.1 part of hydrolytic polymaleic anhydride and 0.05-0.1 part of hexakis(methoxymethyl)melamine. The plastic fishing bit disclosed by the invention is excellent in controlled-speed water solubility and biodegradability in a water body, the mold growth grade is up to a grade V, the weight loss ratio of 15 days is up to 80% or greater, the plastic fishing bait is completely degraded within 30 days, and the plastic fishing bait can meet environmental requirements.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fully degradable plastic processing, in particular to a fully degradable starch / PVA plastic fishing bait and a processing method thereof. [0003] Background technique: [0004] In recent years, with the development of the international and domestic economy and the continuous progress of society, people have higher and higher requirements for the protection of the ecological environment, and the standards for international trade in this area have become more and more stringent. Whether a product can open up the market in a certain country or region is no longer a simple matter of the product’s internal price, quality and safety. The environmental protection of the product, especially whether the degradability of plastic products complies with the environmental regulations of the region has become an essential component. [0005] Starch / PVA polymer materials belong to a category of fully degradable...
