Problems solved by technology

However, the plastic film takes a long time to degrade, and its wide use will cause serious "white pollution"
At present, the main way to solve the "white pollution" of plastic films is to develop degradable agricultural films. The current degradable agricultural films have poor light transmittance, resulting in a reduction in cotton production. After a 60-day induction period and a 150-day degradation period, The fragments are larger than 4×4cm 2 , cannot meet the actual needs

Abstract

The invention discloses a photodegradable plastic film. The film is made of a master batch through blown film, and the master batch includes polyethylene, a photodegradant, a light stabilizer and a lubricant. Compared with the prior art, the mechanical properties of the prepared agricultural film are tested according to the GB 4455-2006 standard, and its tensile strength is ≥14MPa longitudinally and transversely, elongation at break is greater than 300% vertically and transversely, and the right-angle tear strength Longitudinal and transverse ≥55KN / m. The film has good light transmittance, which can increase the production of cotton, and after a 60-day induction period and a 150-day degradation period, the film fragments are less than 1×1cm 2 .

Description

technical field [0001] The invention belongs to degradable plastic films, in particular to photodegradable plastic films containing polyethylene. Background technique [0002] Agricultural mulch can play four functions of moisture conservation, heat preservation, weeding and insecticide, and can greatly increase the yield of crops. The masterbatch of traditional agricultural mulch is polyethylene, which has excellent physical properties. However, the degradation time of this plastic film is long, and its extensive use will cause serious "white pollution". At present, the main way to solve the "white pollution" of plastic films is to develop degradable agricultural films. The current degradable agricultural films have poor light transmittance, resulting in a reduction in cotton production. After a 60-day induction period and a 150-day degradation period, The fragments are larger than 4×4cm 2 , can not meet the actual needs. Invention content: [0003] The technical prob...
