Problems solved by technology

[0004] At present, my country mainly uses ultra-thin mulches below 0.012mm (0.006-0.004mm, or even 0.005-0.003mm). This kind of mulch has low strength, is easy to break, and is difficult to recycle after use. It is discarded in the soil. It has caused serious white pollution to the soil and the environment over the years

Abstract

The invention discloses a black liquid state environment-friendly multifunctional mulching film which comprises the following components in percentage by weight: 20-40wt% of high concentration organic wastewater, 0-30wt% of humic acid, 3-15wt% of a polymerization film-forming agent, 30-70wt% of water, 1-3wt% of a crosslinking agent, 0-20wt% of a stabilizer and 0-20wt% of a land additive. The degradable liquid state mulching film produced by using humic acid and paper making black liquid as raw materials has double effects: temperature increase, soil moisture conservation and seedling prevention, and stronger adhesive capacity. The mulching film can bind soil particles to ideal aggregates.

Description

technical field [0001] The invention relates to the field of biodegradable polymer materials, in particular to provide a black liquid environment-friendly multifunctional plastic film. Background technique [0002] The use of plastic mulch cultivation technology is one of the top ten agricultural technologies well known in this century. The application of mulch can meet the needs of crops in terms of heat preservation, moisture conservation, frost protection, and fertility maintenance. Therefore, plastic mulch is one of the main applications of plastics in agriculture. [0003] In the early 1950s, Japan was the first to promote the application of plastic film mulching cultivation technology. my country introduced this technology from Japan in 1978. Since the 1980s, the use of plastic film has shown an upward trend in fluctuations. Plastic mulch is a high molecular hydrocarbon compound made of polyethylene plus antioxidants and anti-ultraviolet agents. It has the characteris...
