Description

A kind of biological whole degradation plastic and preparation method thereof
Technical field
The present invention relates to plastics preparing technical field, is especially a kind of biological whole degradation plastic and preparation method thereof.
Background technology
As the problems such as environmental pollution and energy shortage is on the rise, the development and application of environmentally friendly material, which turns into, grinds The emphasis studied carefully.For environmentally friendly material using renewable resource as raw material, product has a biodegradability, raw material sources are abundant, Its Devoting Major Efforts To Developing application of product degraded is pollution-free etc. advantage boosting.During product development, degradable polymer is due to making Prepared with non-petroleum class raw material and widely paid close attention to.
Natural fiber is commonly used to replace some synthesis fine due to its cheap and easy to get, renewable and good biocompatibility Tie up to serve as reinforcing agent and filler.In recent years, have increasing natural fiber be used for degradation plastic it is filling-modified with Improve its mechanical property, hot property, crystal property and degradation property.Rice and wheat are as basic primary product, annual production Amount is very big, the byproduct stalk of rice and wheat except packing ring, pasture is used on a small quantity, partly made compost for heap it is outer, it is most of All abandoned or burnt up as fuel；The byproduct wheat bran of wheat is primarily used to feed or discarded, causes very big resource Waste；Research at present focuses primarily upon some compositions of wheat bran or the functional study of component, in the research of other side It is less；Therefore rice straw and wheat bran are not utilized rationally.
But in string containing substantial amounts of hydroxyl, phenolic hydroxyl group, hydrophily is strong, at the same thermoplastic resin hydrophobicity compared with By force, make the interface compatibility of the two poor, simultaneously because the presence of hydroxyl and phenolic hydroxyl group, fiber is easily reunited in process, Dispersiveness is poor, thus the two simple mixing is difficult to reach and should required, so improving its interface compatibility turns into research With the key for preparing natural plant fibre composite.
The content of the invention
The technical problems to be solved by the invention are the shortcomings that overcoming above prior art：A kind of fully bio-degradable is provided Plastics and preparation method thereof.
The technical solution of the present invention is as follows：
A kind of biological whole degradation plastic：It is prepared from the following raw materials in parts by weight：40~60 parts of polycaprolactone, stalk fibre 10~20 parts, 10~20 parts of wheat bran, 5~15 parts of chitosan, biuret modified 4~10 parts of epoxy resin, diphenyl methane two is different 2~8 parts of cyanate, 1~7 part of tributyl 2-acetylcitrate, 2,2- double 0.1~0.5 part of (4- hydroxy phenyls) propane, polypropylene connects 1~8 part of maleic anhydride of branch, 1~5 part of silane coupler, 1~5 part of stearic acid, 1~5 part of carragheen, 1~7 part of glycerine.
A kind of preparation method of biological whole degradation plastic：Comprise the following steps：
(1) pre-treatment of wheat bran：It is 100~150 mesh that wheat bran is crushed into granularity, by the wheat bran after crushing with Water is 1~2 according to mass body:10 are mixed, and the sulphur acid for adjusting pH for adding 1mol/L is 5~6, are heated to 60~80 DEG C of placements 3~4h；Then 5~10 are ultrasonically treated under the conditions of 200~400W of ultrasonic power until after neutral with absolute ethyl alcohol and water washing Minute；It is 4~5 with 1mol/L sulphur acid for adjusting pH, adds alpha-amylase, 20~30min is digested at 40~60 DEG C；Add 1mol/L sodium hydroxide regulation pH is 7.5~8.5, adds at protease is 30~40 DEG C in temperature and digests 20~30min, does It is dry；
(2) modification of stalk fibre：By stalk fibre and silane coupler, chitosan, biuret modified epoxy resin, hard Resin acid is mixed, and input high-speed mixer mixes 5~10 minutes, is dried after taking-up at 20~40 DEG C, produces modified straw Fiber；
(3) mix：The stalk fibre modified with step (2) of wheat bran enzymolysis liquid made from step (1) is mixed, so Polycaprolactone, polypropylene grafted maleic anhydride, methyl diphenylene diisocyanate are added afterwards to be well mixed, and add acetyl lemon Double (4- hydroxy phenyls) the propane carragheens of sour tributyl, 2,2-, glycerine are well mixed, and melting extrusion is carried out with double screw extruder It is granulated, obtains masterbatch；
(4) masterbatch is added in inflation film manufacturing machine through heating up, extruding, being blow molded, upper traction, lower traction and winding film forming, that is, obtain The product of the present invention.
The preparation method of stalk fibre of the present invention is：Water intaking rice or wheat stalk, it is 5~8cm to cut into length, uses clear water Clean, dry or dry at 30~50 DEG C, 5~10min of crushing in pulverizer is then put into, through 2~3h of ball milling in ball mill； Rice straw powder after ball milling and mass percent concentration are handled into 1~2h for 10% sodium hydroxide solution in 40~50 DEG C, It is with absolute ethyl alcohol and water washing until neutral；It is 95 that rice straw after alkali process is added into mass ratio:2:3 NaOH, K2S2O4With And K2In S mixed solutions, filtered with the nylon filter bag of 400 mesh, then with absolute ethyl alcohol and water washing up to neutral, so as to be made Stalk fibre；
The beneficial effects of the invention are as follows：
1st, the present invention in order to solve the problems, such as that the compatibility between stalk fibre and polyester is poor, using silane coupler, Chitosan, biuret modified epoxy resin, stearic acid are surface-treated to stalk fibre, and first, silane coupler can improve The hydrophobicity of fiber surface；Secondly, physical entanglement effect can occur with fiber macromolecular for chitosan, and the amino of chitosan is with gathering The ester group of caprolactone can produce hydrogen bond, and good bridging effect is played to the compatibility of composite, while again because it is day Right macromolecule, therefore the water imbibition of modified obtained composite is also larger；Stearic carboxyl is esterified with hydroxyl in fiber Reaction, reduces fibrous hydrophobic, improves the dispersiveness of fiber, while stearic backbone one side and polycaprolactone There is preferable compatibility, on the other hand can be deep into polycaprolactone phase, mutually wind, enhance with the strand of polycaprolactone The toughness of composite；Excessive epoxy radicals strengthens the polarity of modified fibre in biuret modified epoxy resin, so as to influence Compatibility between fiber and plastic substrate；Therefore by the synergy of these four materials, stalk fibre is substantially increased Compatibility between polyester, so as to improve the mechanical property of composite.
2nd, the present invention uses NaOH, K2S2O4And K2S is handled stalk fibre, and NaOH is in dissolving hemicellulose, wood While plain, cellulose has also inevitably been decomposed, has caused the reduction of fiber self-strength, therefore the present invention is in NaOH processing During, add K2S2O4And K2S auxiliary agents can occur certain with the aldehyde terminal groups of the carbohydrate such as cellulose, hemicellulose Chemical reaction (oxidation, reduction), it is suppressed that " peeling reaction " of carbohydrate, so as to play a part of protecting cellulose.
3rd, a variety of processing aids, such as tributyl 2-acetylcitrate carragheen, glycerine are also added with the present invention, carried significantly Water resistance, hot-workability and the life-span of high polybag of the present invention.Added with double (4- hydroxy phenyls) propane of 2,2- in the present invention The degraded of plastics can be promoted.
4th, the present invention adds stalk fibre of degradable, wheat bran, chitosan etc. in polycaprolactone, so as to improve it is poly- oneself The degradability of lactone, meanwhile, the structural strength and mechanical strength, its tensile strength for improving the present invention are 9~18N/ mm2, fracture strength is 10~28N/mm2, elongation at break is 100~240%.The plastics of the present invention can carry out fully bio-degradable, Can degrade completion for 3~9 months substantially in outdoor, therefore protect environment.
