Description
Technical field
The invention belongs to Storage and Processing of Agricultural Products technical field, and in particular to a kind of degradable antibacterial mulch film.
Background technology
Mulch film looks thin layer, but acts on quite big.Ground temperature, water conservation, soil conservation, fertilizer conservation can not only be improved and improve fertilizer efficiency, and also weed eradication, anti-disease pest, waterlogging-resistant, suppression salt of taking precautions against drought keep a full stand of seedings, improve light and heat condition near the ground, make the multiple functions such as product hygiene.For those just unearthed seedling, with the effect such as mulch growth promoting.For China three northern areas of China, the factor of low temperature, short of rain, arid poor ridge, frost-free period the limitation agricultural development such as short, with very strong specific aim and applicability, for also play effect on two season of plantation raising rice seedlings and various crop cultivation.In the provinces, cities and autonomous regions' popularization of 31, the whole nation and application, for the multiple kinds of crops of grain, cotton, oil, dish, melon and fruit, cigarette, sugar, medicine, fiber crops, tea, woods etc. 40, crop is set generally to increase production 30%-50%, rise in value 40%-60%, deep to be welcome by vast farmerses.
The research and development focus that degradative plastics is just being attracted attention as high-tech product and environment-friendly products as the world today, its development not only expands the function of plastics, and environment contradiction is alleviated to a certain extent, how to produce one kind can be with biodegradation, and plastic sheeting with preferable physical and mechanical property and the features such as well adapting to property is the technical problem to be solved in the present invention.But the film that uses mostly still non-degradable, difficult recovery, the material of difficult to burn at present, these materials are universally acknowledged to the severe contamination of environment；The shortened shelf life of food brings serious loss to manufacturing enterprise caused by packaging material, barrier, the moist, anti-microbial property of resistance of nano packaging material are all significantly increased than common packaging materials, therefore, a kind of degradable antibacterial mulch film how is researched and developed, is the technical problem to be solved in the present invention.
The content of the invention
The purpose of the present invention is providing a kind of degradable antibacterial mulch film, it is ensured that there is the preservation quality of product good Antimicrobial preservative to act on simultaneously, can ensure that Environmental security.
The technical scheme that the present invention takes is：
A kind of degradable antibacterial mulch film, material component proportioning is counted by weight：
Polyvinyl resin 13-15 parts, particle diameter be cornstarch 30-40 part of 4-9 μm, 5-8 parts of basalt fibre of crushing, antiseptic 10-15 parts, 13-15 parts of plasticity starch, 14-16 parts, redispersable latex powder 3-5 parts, coupling agent 4-6 parts, talcum powder 3-5 parts, poly butylene succinate 3-5 parts, fatty acid amide 10-12 parts, plasticizer 1-2 parts of degradable poly caprolactone；
The antiseptic compares 2 for calcium carbonate, silver nano material and TiO2 nano materials according to weight：2:The mixture of 3 compositions.
Further, described degradable poly caprolactone is the kaolin containing 3-5% low-molecular-weight polyhexene waxes.
Further, described coupling agent be containing 5% by cadmium stearate and nano titanium oxide according to 1：The silane coupler model 570 of the mixture of 2 compositions.
Further, a kind of preparation method of degradable antibacterial mulch film is：
（1）Above-mentioned raw materials are taken according to weight proportion, with the rotating speed of 240-260r/min on high-speed mixer, above-mentioned material 30-40min is sufficiently mixed；
（2）Temperature is controlled in molding machine is played for 150-155 DEG C, 25-35min is mediated with the rotating speed of 350-360r/min, be then cut into master batch after extrusion cooling 2-3min；
（3）It is 145 DEG C to control machine barrel charging zone temperature, and plasticizing zone temperature is 165 DEG C, and homogenization zone temperature is 175 DEG C, controls mould temperature for 145 DEG C, and extrusion plasticizing uses blow moulding machine Blown Film.
Beneficial effects of the present invention：
The present invention is by cornstarch and plasticity starch; content of starch highest; in the presence of edaphon; water, carbon dioxide and organic matter can completely be resolved into; it is pollution-free; can be widely applied to agricultural mulching, packaging bag etc.; the synergy of basalt fibre and antiseptic is crushed, with barrier property, extends the storage life of food; there is good Antimicrobial preservative to act on simultaneously; edible safety in shelf life is can ensure that, the film antimicrobial efficiency is high and safety non-toxic, degradable; there is good mechanical property simultaneously, market application foreground is wide.
