Description
Technical field
The present invention relates to a kind of production method of mulch film, specifically is the production method of a kind of tobacco cultivation with the complete biodegradable mulch film.
Background technology
In the tobacco planting cultivation, use plastic film mulching cultivation to have the effect of water conservation, insulation and soil moisture conservation, become the important cultivation technique that the tobacco cultivation industry improves quality of tobacco and output, now in the widespread use of tobacco planting industry.But, because traditional mulch film is generally not biodegradable polythene material and makes, cause the tobacco plastic film mulching cultivation after, mulch film has a large amount of fragments to be difficult to reclaim in the mulch film removal process that cigarette is used, and forms " white pollution " that people are referred to as.Especially in area, the Yunnan-Guizhou Plateau, because illumination is bigger, fragment occurs more serious, not only causes the deterioration of soil to harden, and causes the tobacco underproduction.Therefore,, not only can solve " white pollution " problem, but also alleviate the situation that mulch film is depended on the petrochemical industry resource unduly to a certain extent, alleviate the carbon footprint in the tobacco cultivation process with environment protection aspect developing complete biodegradable cigarette mulch film.Chinese patent literature CN1453303A discloses, and a kind of " biologically degradable starch film and preparation method thereof " adopted polyvinyl alcohol and linking agent to starch conversion, its production method complexity, the cost height, and still contain part can not the complete biodegradable polyethylene, have problems in applications.Chinese patent literature CN1651495A discloses a kind of fully biodegradable mulch film for tobacco and preparation method thereof, its raw materials for production are the petrochemical industry resource material, and cost is higher, are not completely free of the dependence to the petrochemical industry resource yet, consume non-renewable petrochemical industry resource, still have some problems applying.
Summary of the invention
The purpose of this invention is to provide the production method of a kind of tobacco cultivation with the complete biodegradable mulch film, mainly utilize non-petrochemical industry resource to produce, the product of acquisition is complete biodegradable in a short time.
The present invention is achieved through the following technical solutions: a kind of tobacco cultivation production method of complete biodegradable mulch film, it is characterized in that making: thermoplasticity canna starch 15-65, poly(lactic acid) 20-65, softening agent 5-25, expanding material 5-15, toughener 0-5 and processing aid 0.5-2.0 by the raw material of following mass percent, after above each raw material mixed, add in the twin screw extruder at 145-195 ℃ of following extruding pelletization; The gained pellet is added in single screw rod extrusion blow molding machine barrel by hopper, and the control extrusion temperature promptly obtains tobacco cultivation complete biodegradable mulch film 175-205 ℃ of blow molding.
Described thermoplasticity canna starch is the bajiao banana taro thermoplastic starch through gelatinization, oxidation or esterification treatment.
Described poly(lactic acid) is chemosynthesis or the toughness reinforcing polydactyl acid of physical blending.
Described softening agent be in, the polyol polyester in the low-molecular-weight polyester, one or both mixtures in poly-succinic glyceryl ester, the polyoxyethylene glycol season luxuriant tetrol fat.
Described expanding material is maleic anhydride or acrylic graft-modified polylactic acid low polymer.
Described toughener is the Microcrystalline Cellulose that extracts in the plant.
Described processing aid is a composite auxiliary for processing, specifically is stearic acid or oleic acid or its ester cpds.
The present invention uses reproducible plant resources starch to make as raw material: poly(lactic acid) is a kind of novel biodegradable material; it is that starch material is made lactic acid through fermenting process; convert poly(lactic acid) to by chemosynthesis again; has good biodegradability; can be degraded fully by the occurring in nature microorganism after the use, finally generate carbonic acid gas and water, free from environmental pollution; this is highly beneficial to the protection environment, is the environmental friendliness macromolecular material of generally acknowledging.Poly(lactic acid) is applicable to various working methods such as blowing, thermoplastic, and is easy to process, uses very extensive.But poly(lactic acid) degraded required time is not short.
The bajiao banana taro has another name called non-irrigated lotus root, any of several broadleaf plants lotus root, achira, is the plant of Lowiaceae Canna generalis Bailey genus.The canna starch grain diameter is big, and gelatinization point is low, and the paste transparency is good, starch content height, good film-forming property.The development and use of bajiao banana taro at present to be to produce starch, as food such as bean vermicelli, vermicelli, monosodium glutamates, and Dian Fentangs such as glucose, Sorghum vulgare Pers. Maltose, for multiple nonstaple food such as lotus root starch.Be used in sizing and papermaking, clothes and the cultural goods etc. of textile industry at industrial canna starch.The starch content height of bajiao banana taro, protein, fat, the ash impurity that grades is few, has characteristics such as caking ability height, smooth finish be good.Canna starch is 62 ℃ of left and right sides gelatinizations, and hot gelatinization stability is than higher.
The present invention is with biomass canna starch and the poly(lactic acid) main raw material as the preparation mulch film, and with canna starch through gelatinization or esterification modification, increased the poly(lactic acid) avidity and the mechanical property on starch surface, also accelerated the biodegradation rate of mulch film.The present invention adds softening agent, expanding material, toughener and the processing aid of selecting after research trial repeatedly in main raw material, the processing characteristics of main raw material is improved, and quality product is improved.The product of preparation not only can satisfy the production service requirements of tobacco cultivation, product has certain ventilation property, oxygen-permeable and saturating carbonic acid gas, and in the cultivation process of plant tobacco, need not expire behind the overlay film and take off film and natural degradation, but treat to plough under after the tobacco crop is gathered in the soil just all biological degraded, overcome consume petroleum resource and use soil deterioration and " white pollution " problem that the back exists of traditional mulch film.
Tobacco cultivation of the present invention is simple, easy to operate with complete biodegradable ground film production process, and product cost is low, uses the full biology in back to fall, and has solved present tobacco cultivation with soil deterioration and " white pollution " problem that plastic film produced, compliance with environmental protection requirements.
The present invention also has the following advantages:
(1) the present invention is a material of main part by non-grain bajiao banana taro treated starch, and its source is abundant, and that can avoid that traditional employing food starch causes strives the grain situation with the people.
(2) the present invention has been owing to added softening agent, expanding material, toughener and processing aid through selecting, thereby improved every performance of blown film material; Additive is a full-biodegradable material, can effectively solve the conventional plastic mulch film to the dependence of petrochemical industry resource and be applied to soil deterioration and " white pollution " that tobacco cultivation causes.
(3) tobacco cultivation of the present invention's production is simple with complete biodegradable mulch film complete processing, can adopt existing mulch film blow moulding equipment blown film, simple and practical production method.
(4) raw material sources of the present invention are wide, are renewable material, low-carbon environment-friendly, and production cost is low, invests for a short time, has each environmental protection benefit of better economic society.
