Abstract

The invention relates to a biodegradable additive prepared from a copper powder, an iron powder, a silane coupling agent, a titanate coupling agent and low density polyethylene as raw materials, wherein the biodegradable additive comprises the following components: 8 to 12 mass% of the copper powder, 8 to 12 mass% of the iron powder, 0.5 to 1.5 mass% of the silane coupling agent, 0.5 to 1.0 mass% of the titanate coupling agent, and the balance low density polyethylene. The invention also relates to a preparation method of the biodegradable additive and plastic products with addition of the biodegradable additive, especially polyethylene plastic thin film products, wherein the plastic products have good biodegradability and do not produce white pollution.

Description

technical field [0001] The invention relates to a biodegradation additive which can impart biodegradability to plastic products. The invention also relates to a plastic product prepared by adding the biodegradation additive, in particular to a polyethylene plastic film prepared by adding the biodegradation additive. Background technique [0002] Plastic is a cheap and high-quality material. However, with the widespread use of plastic products such as plastic convenience bags and plastic films, the problem of "white pollution" has become increasingly prominent. This is because the intrinsic life of plastic products (from finished product to complete natural decomposition) is much longer than its service life. The inherent durability of plastic allows it to persist in nature and accumulate if left untreated. At present, the main methods to solve this problem are deep burial and incineration, etc., but deep burial occupies cultivated land, pollutes groundwater, changes soil st...
