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 film is to develop degradable agricultural film. The current degradable agricultural film has poor light transmission, which leads to the reduction of cotton production. After a 60-day induction period and a 150-day degradation period, its Fragments larger than 4×4cm 2 , cannot meet the actual needs

Abstract

The invention discloses a biodegradable plastic film, which is prepared by performing film blowing on a master batch, wherein the master batch comprises the following substances: polyethylene, a 1 to 2 [mu]m filler, a degrading agent, a dispersant and a lubricant. Compared with the prior art, the prepared agricultural film has the advantages that detection of the mechanical performance according to standard GB 4455-2006 shows that the longitudinal and transverse tensile strength is more than or equal to 14 MPa, the longitudinal and transverse breaking elongation is more than or equal to 300 percent, and the longitudinal and transverse tangential breaking strength is more than or equal to 55 KN / m; the film is high in light transmittance, and has a yield increasing effect on cotton, and film fragments maintained after a 60-day induction period and a 150-day degradation period are 1*1 cm<2>.

Description

technical field [0001] The invention belongs to degradable plastic films, in particular to biodegradable 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 film is to develop degradable agricultural film. The current degradable agricultural film has poor light transmittance, which leads to the reduction of cotton production. After a 60-day induction period and a 150-day degradation period, its Fragments larger than 4×4cm 2 , can not meet the actual needs. Invention content: [0003] The technical problem to...
