Problems solved by technology

The disposal of waste toys has become a big problem. If it is not handled properly, a large amount of plastic will become a "killer" that damages the environment; and the recycling cost of plastic is relatively high, and it needs to go through multiple processes before it can be recycled.

Abstract

The invention discloses a fully-degradable starch / PVA plastic toy and a processing method thereof, and relates to the technical field of processing of fully-degradable plastic. The fully-degradable starch / PVA plastic toy is prepared from the following raw materials in parts by weight: 25 to 30 parts of plant starch, 15 to 20 parts of polyvinyl alcohol, 3 to 5 parts of sepiolite powder, 3 to 5 parts of biodegradable additives, 2 to 3 parts of calcined kaolin, 2 to 3 parts of an environment-friendly plasticizer, 0.5 to 1 part of molecular sieve raw powder, 0.5 to 1 part of a crosslinking agent, 0.05 to 0.1 part of sepiolite fiber powder and 0.05 to 0.1 part of tea seed powder. The plastic toy has excellent biodegradability, the mycete growth level reaches level V, the 30-day weight loss ratio reaches about 80 percent, and the plastic toy can be biodegraded completely within 60 days, so that the plastic toy accords with the environmental protection requirement and solves the problems that the environment is difficult to degrade and the recycling cost is high in the common plastic toy.

Description

Technical field: [0001] The invention relates to the technical field of fully degradable plastic processing, in particular to a fully degradable starch / PVA plastic toy and a processing method thereof. Background technique: [0002] 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. [0003] Starch / PVA polymer materials belong to a category of fully degradable materials. They not onl...
