Special weather-resisting functional mulching film capable of being used for two years

Abstract

The invention provides a special weather-resisting functional mulching film capable of being used for two years. The special weather-resisting functional mulching film is prepared from the following raw materials in percentage by weight: 60-80% of LLDPE (Linear Low Density Polyethylene), 5-15% of LDPE (Low-Density Polyethylene), 3-8% of HDPE (High-Density Polyethylene), 5-15% of mPE (Metallocene Polyethylene) and 2-6% of anti-ageing master batch. The anti-ageing master batch is prepared from the following raw materials in percentage by weight: 35-45% of LLDPE powder, 25-35% of the LDPE, 6-15% of the HDPE, 5-12% of the mPE, 2-7% of a hindered amine light stabilizing agent, 0.5-3.5% of an antioxidant, 0.5-3.5% of an ultraviolet absorber and 1..5-5.0% of dispersing agent white oil. The special weather-resisting functional mulching film can meet the requirements of 'one film with two-year service life' of the weather-resisting functional mulching film and can be used for 12-18 months; and compared with the common mulching film, the culture under-glass increased production reaches to 30-40%, so that the stable agriculture is realized and the good supply is guaranteed.

Description

technical field [0001] The invention relates to an agricultural ground covering film, in particular to a special weather-resistant functional mulching film suitable for full-film covering and double-furrow sowing technology. Background technique [0002] The application of plastic film in agricultural production is an epoch-making progress in the use of solar energy by human beings. It has made great contributions to the realization of the "food and clothing project" and "vegetable basket project" in my country, and has become an indispensable means of production in the two high and one excellent . According to the statistics of relevant departments, the annual consumption of plastic film in my country is more than 1.25 million tons, the covered cultivation area is more than 350 million mu, and the area suitable for plastic film covering cultivation is 700 million mu, and the usage is increasing year by year. However, with the extensive use of medium and low-grade plastic mu...
