Abstract
The invention discloses an oxidized-biodegradable plastic bag which is attractive in price and quality and is prepared from the following raw materials in percentage by weight: 40% of low density polyethylene (LDPE), 12% of metallocene line type polyethylene (MLLPE), 45% of corn starch pasting modified master batch and 3% of hydroperoxide inosine diphosphate (IDP) master batch. The oxidized-biodegradable plastic bag provided by the invention can be used as shopping bags, continuously-wound and flat-edge fresh-keeping bags, rubbish bags, dinner cloth and the like, and the degradation effect of the oxidized-biodegradable plastic bag meets the national standards. Within 6 to 9 months in the natural environment after being abandoned, the oxidized-biodegradable plastic bag is converted into powder with a physical strength of zero, and then converted into a fertilizer beneficial to plant growth and finally converted into carbon dioxide and water. The oxidized-biodegradable plastic bag is only about 20% more expensive than the ordinary plastic bag in price, and the oxidized-biodegradable plastic bag provided by the invention can be used for eliminating the white pollution fundamentally,thus an effective and economical product which is easy to popularize is invented.
Description
Technical field
The present invention relates to widely used plastic shopping bag, connect roll up fresh-keeping flat mouth bag, refuse bag, platform (table) but the manufacturing technology of the natural degradation plastic film of cloth etc. refers in particular to a kind of oxidized-biodegradable plastic bag and preparation method thereof.
Background technology
At present, known plastic shopping bag, connect roll up fresh-keeping flat mouth bag, refuse bag, platform (table) cloth be in 50 years can not natural degradation material, form white pollution after discarded.Even recycling, its cost recovery is too high, does not possess operability.Restriction is used even if government takes measures, and also can't solve white pollution problems at all.Although poly(lactic acid) (PAL), PBT full-biodegradable material have appearred in market in succession in recent years, but its price is 3-4 times of the common plastics bag, can't popularize use, and light degradation, starch base filled biomass degradative plastic bag be also because hard to tell whether it is true or false, and treated coldly by market.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cheap and degradable oxidized-biodegradable plastic bag of short period, and the present invention simultaneously also provides the preparation method of this product.
The technical scheme that the present invention solves the problems of the technologies described above employing is:
Oxidized-biodegradable plastic bag, it is made by the raw material of following weight percentum:
Low Density Polyethylene (LDPE) 40%, metallocene Hi-fax (MLLPE) 12%, corn starch pasting modified master 45% is crossed hydroxide (IDP) masterbatch 3%.
The preparation method of above-mentioned oxidized-biodegradable plastic bag, the preparation method is as follows:
According to above formula, four kinds of raw materials add batch mixer simultaneously, after mixing, use common inflation film manufacturing machine, adopt the high pressure polyethylene film-blowing process, and temperature is arranged on 135 degree to 170 degree scopes, gets final product normal blown film, printing, bag.
The technological advance that the present invention obtains is: the oxidized-biodegradable plastic bag that the present invention is prepared from has a kind of special texture, the face light yellow complexion, obvious corn snuff fragrance is arranged, and the feel particularly soft is as silk, and common people can accurately identify.This product has reached respectively QB/T 2461-1999, GB/T21661-2008, GB/T 21660-2008, HJ/T209-2005 standard.Can under oxidizing process and biological assimilation, be converted into the organic fertilizer that is conducive to plant growth at 6 months in 9 months in the environment that natural daylight, oxygen, moisture content, bacterium are arranged, finally generate carbon dioxide and water.And its market price has possessed only than expensive 20% left and right of common plastics bag the condition that promotes the popularization use fully.Photo-thermal oxidation biodegradation promotor (IDP) is a kind of hydroxide agent of crossing, and is the product that Xiner Synthesizing Risen Material Co., Ltd., Shanghai researches and develops and puts on market.It is a kind of under ultraviolet action of thermal difference with there being temperature traverse to form, can produce the hydroxide of crossing of a large amount of free radicals, be the compound of one kind of multiple rare metals, coats through modification, make masterbatch, play the biodegradable effect of promotion polyolefine material oxidation.This accelerator can evenly dissolve in the polyolefin body, and after goods went out of use, under the effect of light and heat, IDP was activated, and produces a large amount of free radicals.Under the free radical successive reaction, produce a large amount of carbonyls.Polyolefinic structure of matter generation chemical change, mol wt sharply descends, and physical strength levels off to zero, and the size of IDP dosage is directly proportional to degradation speed.The corn starch pasting modified master that adds is in recent years about the new process of the filling-modified masterbatch of cornstarch.Be a kind of need not with starch refinement, drying and dehydrating again modification coat, directly coat again to starch conversion the filling-modified masterbatch of cornstarch that the gelatinization treatment process produces.Except Xiner Synthesizing Risen Material Co., Ltd., Shanghai put on market in batches, the ground such as Nanjing, Guangzhou had 2 companies also to have like product to supply market.The corn starch pasting modified master is through the heating film-blowing process, and a kind of puffed rice taste is dense, and the smooth softness of goods, as the feel as silk is a kind of peculiar texture, obviously is different from other plastic bags.Under biological assimilation, the starch thing is converted into the fertilizer that is conducive to plant growth, finally generates carbon dioxide and water.The blown film temperature is controlled at below 170 ℃, seals, prints all the same with other raw material.
The specific embodiment
Embodiment: a kind of oxidized-biodegradable plastic bag, it is made by the composition of raw materials of following weight percentum:
Low Density Polyethylene (LDPE) 40%, metallocene Hi-fax (MLLPE) 12%, corn starch pasting modified master 45% is crossed hydroxide (IDP) masterbatch 3%.The preparation method is as follows: according to above formula, four kinds of raw materials add batch mixer simultaneously, after mixing, use common inflation film manufacturing machine, adopt the high pressure polyethylene film-blowing process, and temperature is arranged on 135 degree to 170 degree scopes, gets final product normal blown film, printing, bag.
Claims (2)
1. oxidized-biodegradable plastic bag is characterized in that it is made by the composition of raw materials of following weight percentum:
Low Density Polyethylene (LDPE) 40%, metallocene Hi-fax (MLLPE) 12%, corn starch pasting modified master 45% is crossed hydroxide (IDP) masterbatch 3%.
2. the preparation method of oxidized-biodegradable plastic bag according to claim 1, it is characterized in that the preparation method is as follows: according to above formula, four kinds of raw materials add batch mixer simultaneously, after mixing, use common inflation film manufacturing machine, adopt the high pressure polyethylene film-blowing process, temperature is arranged on 135 degree to 170 degree scopes, gets final product normal blown film, printing, bag.
