Abstract
The invention discloses a plastic master batch for a degradable environment-friendly shopping bag. The plastic master batch comprises the following ingredients by weight percent: 2-3% of stearic acid, 5-6% of calcium stearate, 6-8% of a titanate coupling agent, 12-16% of heavy calcium carbonate powder, 4-6% of liquid paraffin, 16-18% of ethylene-methyl acrylate copolymer, 12-14% of linear polyethylene, 8-10% of high density polyethylene, and the balance of low density polyethylene.
Description
Technical field
The present invention relates to field of packaging material, relate in particular to a kind of Degradable environment protection shopping bag plastic master batch.
Background technology
The shopping bag that supermarket, market, country fair etc. provide is all to adopt the polymer materialss such as polystyrene, polyethylene, polypropylene to make substantially, because they cannot be degraded, ecotope is done great damage, threatening the space of human survival, people are referred to as " white pollution ".For this reason, general office of State Council of the People's Republic of China has issued " selling the notice that uses plastic shopping bag about limit production ".According to notice, in view of shopping bag becomes the main source of " white pollution ", the various places People's Government, ministries and commissions etc. should forbid producing, selling and uying super-thin plastic shopping bag, and will carry out plastic shopping bag Paid Use System from now on.From 1 day June in 2008, plastic shopping bag Paid Use System was carried out in commodity retail place in all supermarkets, market, country fair etc., must not provide free without exception plastic shopping bag.Although paid utilization has limited the shopping bag of some amount, the pollution problem of shopping bag itself is not still resolved.
For this reason, people start degradable package bag to study gradually, and increasing degradative plastics goods start to emerge in large numbers.But always there is such or such deficiency in current degradation products.At present many is that employing petroleum-based plastics polyolefine material is that carrier is prepared degradative plastics, or adopt the polylactic acid-based macromolecular material of preparing from crude substance to improve the biological degradability of degradative plastics, but, the resistance toheat deficiency of material after processing, be difficult to meet the service requirements of shopping bag, and the cost compare of poly(lactic acid) is high.
For example, application number is the blend that has adopted degradable high polymer material and natural macromolecular material in 200710190063.8 patent, to solving the contradiction between Performance and Cost Modeling, wherein, the content of poly(lactic acid) and thermoplastic starch is 1: 1 substantially, although this scheme makes moderate progress to the performance of product, still not ideal enough and cost is still very high.
Summary of the invention
The object of the invention is to propose a kind of Degradable environment protection shopping bag plastic master batch, this master batch, by the adjustment of component, makes the starch-based degradable shopping bag take it as master batch have enough intensity and toughness and deflection, meets service requirements.
For reaching this object, the present invention by the following technical solutions:
A kind of Degradable environment protection shopping bag plastic master batch, the composition of this plastic master batch is made up of following component by weight percentage: stearic acid 2-3%, calcium stearate 5-6%, titanate coupling agent 6-8%, heavy calcium carbonate 12-16%, whiteruss 4-6%, ethylene-methyl acrylate copolymer 16-18%, linear polyethylene 12-14%, high density polyethylene(HDPE) 8-10%, surplus is Low Density Polyethylene.
Preferably, the composition of this plastic master batch is made up of following component by weight percentage: stearic acid 2.5%, calcium stearate 5.5%, titanate coupling agent 7%, heavy calcium carbonate 14%, whiteruss 5%, ethylene-methyl acrylate copolymer 17%, linear polyethylene 13%, high density polyethylene(HDPE) 9%, surplus is Low Density Polyethylene.
This master batch can be prepared as follows: in proportion stearic acid, calcium stearate, titanate coupling agent, heavy calcium carbonate, whiteruss, ethylene-methyl acrylate copolymer, Low Density Polyethylene, linear polyethylene, high density polyethylene(HDPE) are put into high-speed kneading machine, be heated to 115-125 ℃ and start stir, stir 14-16 minute; Compound is put into twin screw extruder, granulation on twin screw extruder at 155-165 ℃ of temperature.
Master batch of the present invention, for the preparation of starch-based degradable packing bag, mixes rear granulation blowing with starch according to the ratio of 1:2-3 by this master batch.
Beneficial effect of the present invention is:
Master batch of the present invention, by the adjustment of component, makes the starch-based degradable shopping bag take it as master batch have enough intensity and toughness and deflection, meets service requirements.
