Abstract
A biodegradable plastic container is prepared from the biodegradable basic material (high-density polyethene or starch), elastomer, and linear low-density polyethene through proportionally mixing, and blow moulding. Its advantages are environmental protection and high compression strength and impact strength.
Description
Technical field
The present invention relates to the technology of amyloid bio-degradable plastics, and the production method of its vessel prepd, the plastic manufacturing technology field belonged to.
Background technology
Plastics are since coming out, because performances such as its distinctive corrosion-resistant, easy processing have obtained using widely.But common plastics mostly do not possess degradation property, and along with the rapid increase of plastics usage quantity and the people intensification day by day to the environment protection understanding of importance, the plastics of how handling after the use become a great problem.Plastics of a great variety, handled and need expend great amount of manpower, financial resources again its recovery; In many occasions, the plastics after the use often can not reclaim.
In order to address the above problem, degradable plastics comes into one's own.Degradable plastics comprises photodegradation and biodegradable plastic etc.The shortcoming of photodegradable plastics is the cost height, and degradation speed is wayward, and buried plastics can not be degraded.
Biodegradable plastics are common to be mixed and made into by biodegradable starch and the macromolecular compound that is difficult for degraded, and biological degradation can take place resulting composition.
Now, biodegradable plastics generally have been used for fields such as agricultural, packing and daily one-time consumption product.But, the self-technique of biodegradable plastics as more rational technical recipe, accurately degrade time control, with the back fast degradation property, thoroughly the technology such as recycling of degradation property and scrap stock still await further perfect.
Amyloid bio-degradable plastics is the important degradable plastics of a class.
Starch used herein is modified starch, needs to mix with plastics then through suitable processing (generally also need under molten state);
Plastics used herein can be macromolecular materials such as polyethylene, medium-density polyethylene, high density polyethylene(HDPE), polypropylene.
The general preparation method of amyloid bio-degradable plastics vessel prepd is that macromolecular material, modified starch and plastics additive etc. are mixing evenly, is processed into product with methods such as common extrusion-blown modlings.
Because the raw material that the extrusion-blown modling working method is used is common to be single macromolecular material, and melting index is had certain area requirement.And after adding modified starch etc., can influence the processing characteristics of bio-degradable plastics, the too high amylolysis that causes of Yin Wendu usually during blow molding produces burnt grain, causes the resistance to impact shock of goods, ultimate compression strength to descend.Especially when adding at high proportion modified starch, this situation becomes even more serious.
Summary of the invention
The invention provides a kind of bio-degradable plastics, it is relatively poor to have overcome present amyloid bio-degradable plastics Drawing abillity, complete processing difficulty, the shortcoming that the resistance to impact shock of goods, ultimate compression strength descend.The present invention also provides the production method of this bio-degradable plastics container.
The technical scheme of this bio-degradable plastics of the present invention and vessel prepd thereof comprises:
1, adding in macromolecular material with starch is the biodegradable master batch of main component, and auxiliary materials such as elastomerics, linear low density polyethylene, mixes;
2, compound is processed into vessel prepd through preheating, plasticizing, extrusion-blown modling.
The macromolecular material here can be any in polyethylene, medium-density polyethylene, high density polyethylene(HDPE), the polypropylene etc.
Here be the biodegradable master batch of main component with starch, adopt through connecing the starch of technological transformation: on the starch molecule main chain, connect the skill lipophilic molecules, and compatible with vector resin, disperse, plasticizing, make the biodegradable master batch of acquisition have the characteristic of plastics itself.
For increasing the smooth finish of mobile and product surface, select for use the higher resin of melting index as vector resin, and select the auxiliary agents such as starch, adding compatilizer, dispersion agent, softening agent of suitable fineness for use.Mix, on twin screw extruder, be processed into biodegradable master batch.
What meet above-mentioned technical requirements is the biodegradable master batch of main component with starch, also can obtain on market, and for example: Linda Plastic Chemistry Co., Ltd., Shanghai produces, the trade mark is the biodegradable master batch of S 1212.
The flexible body of the auxiliary material here, linear low density polyethylene;
Can also comprise in the auxiliary agents such as lubricant, softening agent any one or a few.
The working method here relates to the production method of bio-degradable plastics vessel prepd:
In macromolecular materials such as polyethylene, medium-density polyethylene, high density polyethylene(HDPE), polypropylene, add auxiliary agents such as a certain proportion of biodegradable master batch, elastomerics, linear low density polyethylene, lubricant, mix;
Compound enters blow moulding machine, is processed into vessel prepd through preheating, plasticizing, extrusion-blown modling.
In order to make the compound can normal blow molding, and avoid temperature too highly to cause burnt grain phenomenon, influence vessel prepd intensity, need each section of adjustment processing temperature, extruded velocity; Adjust the thickness at vessel prepd thin-walled position, increase vessel prepd intensity.
For example, different according to the actual prescription of compound, the processing temperature of extrusion-blown modling can be preferably 150～175 ℃ in 100-200 ℃ of scope.
The ratio of the biodegradable master batch that adds is high more, and the biodegradability of goods is good more, but can influence the physical index and the moulding difficulty of goods simultaneously.Need adopt suitable additional proportion to auxiliary agents such as the biodegradable master batch that adds, elastomerics, linear low density polyethylene, lubricants.
For example, macromolecular material can be 20～80 weight parts, and 40～45 weight parts are better;
Biodegradable master batch is 50～40 weight parts;
Auxiliary agents such as elastomerics, linear low density polyethylene, lubricant are 10～15 weight parts.
As required, can also add softening agent, polyvalent alcohol for example, the incomplete esterification products of wherein preferred propylene glycol, glycerol, tetramethylolmethane, sorbyl alcohol or they and longer chain fatty acid such as glyceryl monostearate etc.;
As required, can also add lubricant, for example stearic acid or stearic metal-salt are as calcium stearate, Magnesium Stearate and barium stearate etc.
This bio-degradable plastics container provided by the invention, the processing characteristics that has overcome present amyloid bio-degradable plastics is relatively poor, complete processing difficulty, the shortcoming that the resistance to impact shock of goods, ultimate compression strength descend.It is extensive to have raw material sources, and cost is low, characteristics easy to process.The production method of this bio-degradable plastics container provided by the invention adopts extrusion and blow molding, and the goods that obtained meet the requirement of use, reaches the related standards that country formulates fully, has biodegradable performance.To alleviating white pollution, protecting environment to have positive effect, can be applied on the wrapping material such as Agricultural products, daily necessities, makeup, medicine, washing composition.
