Abstract
The invention discloses an antibacterial and anti-insect fully-degradable plastic film. According to the invention, polyvinyl alcohol and rice protein powder are used as main film forming substances, and compared with the prior art, nano silica and rice protein powder are modified by a physical and chemical method, and at the same time, a certain amount of inorganic nano additive subjected to surface treatment is added and other effective components are matched, thus greatly reducing the dosage of micromolecular plasticizer, lowering cost, ensuring that hydroxys in the rice protein powder and polyvinyl alcohol molecules can be preferentially bonded with hydroxys on the surface of a proper amount of nano silica to form hydrogen bonds, increasing mutual dissolution of rice protein powder and polyvinyl and improving film water resistance. The prepared fully-degradable plastic film has the advantages of antibiosis, insect prevention, high toughness, and high degradation efficiency, and the problems that the mechanical property of the film at the late stage is reduced and a package is polluted by leachables are avoided.
Description
Technical field
The present invention relates to natural macromolecular material technical field, be specifically related to a kind of antibacterial anti-insect type Based Full-degradable Plastics Film and preparation method thereof.
Background technology
Synthesized polymer material also causes serious pollution to environment while bringing great convenience to the life of people, in addition the continuous minimizing of the prospective oil of conventional plastic is manufactured, thus reproducible eco-friendly natural macromolecular material becomes the focus of research, Mierocrystalline cellulose, starch, protein etc. are current practical study and apply more natural polymer, so natural polymer subtype Wholly-degradable material becomes one of study hotspot of novel environmental friendly material.
Natural polymer because its raw material sources are wide, biodegradability is strong and film forming properties excellence is subject to extensive concern in food product pack and mulch film Application Areas.But, the feature due to natural polymer itself: its range of application of the drawbacks limit such as poor processability, fragility are very much not water-fast.Often adopt plasticising for addressing this problem, acid adjusted, crosslinked, fill or the single method of modifying such as blended, but this single method of modifying is limited, the Based Full-degradable Plastics Film function singleness prepared and cost is high cannot realize its suitability for industrialized production.Nanometer silicon dioxide material has the special functional effect of nanoparticle, improve separately natural macromolecule membrane and PVA (PVOH) FILM mechanical property and water resistance aspect with it and all have obvious effect, and few with the research report of nano-silicon dioxide modified natural polymer and polyvinyl alcohol compound film.
Summary of the invention
Object of the present invention is just to provide a kind of antibacterial anti-insect type Based Full-degradable Plastics Film and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of antibacterial anti-insect type Based Full-degradable Plastics Film, it is characterized in that, be made up of the raw material of following weight part: polyvinyl alcohol 100-110, rice protein powder 48-54, garlic protein powder 3.4-6.2, nano silicon 1.5-3.8, nano titanium oxide 0.8-1.5, sodium alginate 0.3-0.6, Tenox PG 0.7-1.2, ethylene glycol monoisobutyl ether 8-11, oxidation soybean oil 2-4, far-infrared negative-ion powder 3-5, suitable quantity of water.
The preparation method of described a kind of antibacterial anti-insect type Based Full-degradable Plastics Film, is characterized in that comprising the following steps:
(1) rice protein powder, garlic protein powder are added suitable quantity of water and stir into paste, heating pre-gelatinized process 10-20 minute, add sodium alginate, Tenox PG, constant temperature is uniformly mixed 2-3h, and suction filtration dries to obtain modification rice protein powder naturally;
(2) far-infrared negative-ion powder is calcined 30-50 minute at 700-760 DEG C, cooling adds ethylene glycol monoisobutyl ether, oxidation soybean oil, nano silicon agitation grinding 2-3 hour, dries;
(3) polyvinyl alcohol is put into 80-90 DEG C of water-bath and be incubated 30-40 minute, add step (1), (2) material in 55-65 DEG C of water-bath 40-50 minute, then add other remaining components stirring 1-2 hour, put into twin screw extruder granulation;
(4) particle obtained for step (3) is poured in inflation film manufacturing machine at 140-170 DEG C, carry out blown film.
The present invention has following beneficial effect: the present invention adopts polyvinyl alcohol and rice protein powder to be main film forming substance, compare the present invention to carry out modification by physico-chemical process to nano silicon and rice protein powder and simultaneously to add again with traditional technology and a certain amount ofly coordinate other effective constituents to cooperatively interact through surface-treated inorganic nano auxiliary agent, not only greatly reduce the consumption of small molecules softening agent, reduce costs, hydroxyl in rice protein powder and polyvinyl alcohol molecule can also be made preferential and proper amount of nano silica sphere hydroxy combining formation hydrogen bond, increase the compatibility of rice protein powder and polyvinyl alcohol, improve film water tolerance, obtained Based Full-degradable Plastics Film has antibacterial insect protected, toughness is large, degradation efficiency advantages of higher, avoid the mechanical properties decrease in film later stage and separate out the problem polluting packed article.
