Abstract

The invention discloses a kind of can the master batch of fast degraded biologically plastic pellet, including following material: polyethylene, the implant of 1 2um, degradation agent, dispersant, lubricant.Compared with prior art, the mechanical property of the plastic film for agricultural use prepared by master batch presses GB 4,455 2006 standard detection to the present invention, its hot strength vertical, horizontal >=14MPa, elongation at break vertical, horizontal >=300%, angle tear strength vertical, horizontal >=55KN/m.The light transmission of this film is good, and Cotton Gossypii plays a part volume increase, and after the induction period of 60 days, the degradative phase of 90 days, its thin film relic is less than 4 × 4cm2。

Description

A kind of can the master batch of fast degraded biologically plastic pellet
Technical field
The invention belongs to a kind of degradable plastic masterbatch, particularly belong to the biodegradable plastic master batch containing polyethylene.
Background technology
Agricultural mulching can play soil moisture conservation, insulation, weeding, parasite killing four kinds effect, can increase substantially the yield of crops. The master batch of tradition agricultural mulching is polyethylene, and this material has the physical property of excellence.But the degradation time of this plastic sheeting Long, it is widely used and can cause serious " white pollution ".The main path solving plastic sheeting " white pollution " at present is exploitation Degradable agricultural film, current degradable agricultural film, its light transmission is poor, causes the underproduction of Cotton Gossypii, and through the induction period of 60 days, The degradative phase of 150 days, its relic is more than 4 × 4cm2, it is impossible to meet actual needs.
Summary of the invention:
The technical problem to be solved is to provide a kind of induction period through 60 days, after the degradative phase of 90 days, its Relic is less than 4 × 4cm2Plastic master batch.
The present invention solves the technical scheme of technical problem: a kind of can the master batch of fast degraded biologically plastic pellet, including Following material and weight portion:
Described implant includes following material and weight portion:
Calcium carbonate 40-50
Semen Maydis powder 40-50
Described Semen Maydis powder processes through hydrophobization, and detailed process is as follows:
By the Semen Maydis powder that crushes in the case of stirring, add hydrophobic modifier, normal temperature modified 1-2 hour,；Beautiful Rice flour is 100:1-2 with the weight ratio of hydrophobic modifier；
Described hydrophobic modifier is silane coupler, and model is kh550, raw by Nanjing Chuan Shi auxiliary chemicals company limited Produce.
Described degradation agent is 1-oxygen-acetyl inulicin.
Described dispersant is hyper-dispersant, and model is that YY502 is produced by Guangzhou Yuan Tai synthetic material company limited.
Described lubricant is zinc stearate；
Described polyethylene includes that the line style of high density polyethylene (HDPE) that concentration expressed in percentage by weight is 60-75% and 25-40% is low Density polyethylene；
After utilizing prior art to carry out blending extrusion polyethylene, implant, degradation agent, lubricant, dispersant, make mother Grain.
The present invention is compared with present technology, and the mechanical property of the plastic film for agricultural use prepared by master batch presses the inspection of GB4455-2006 standard Survey, its hot strength vertical, horizontal >=14MPa, elongation at break vertical, horizontal >=300%, angle tear strength vertical, horizontal >= 55KN/m.The light transmission of this film is good, and Cotton Gossypii plays a part volume increase, and through the induction period degradative phase of 90 days of 60 days After, its thin film relic is less than 4 × 4cm2。
