Abstract
The invention discloses a kind of nano zine oxide enhancing starch/PBAT degradation materials and preparation method thereof, the packaging film is made of following raw materials in parts by weight: 10-30 parts of starch, 70-90 parts of PBAT, 3-12 parts of glycerol, 0.3-1.2 parts of release agent, 0-2 parts of nano zine oxide, 0.2-1.5 parts of lauric acid, 0.1-0.9 parts of compatilizer, wherein the dosage of methylene chloride is that the mass ratio of its volume and PBAT are 4~8mL:1g.Glycerol, lauric acid and compatilizer are added during starch gelatinization and is modified that plasticizing modified starch is made to it by the present invention, it then is into film base material with starch and PBAT, by dichloromethane solvent, it is completely dissolved PBAT, starch and nano zine oxide are evenly dispersed in a solvent, and release agent is added, finally obtained nano zine oxide enhances tapioca/PBAT film.The filming technology is simple and easy, film obtained has good mechanical performance and water preventing ability, lower light transmittance and water absorption rate, higher contact angle, and it can be with complete biodegradable, with certain practical value, it can be used for refuse bag, the packaging bag to hygienic no requirement (NR), the fields such as agricultural mulching and industrial film.
Description
Technical field
The invention belongs to field of packaging material, specifically a kind of nano zine oxide enhancing tapioca/PBAT can drop
Solve material.
Background technique
Petroleum-based plastics are light inexpensive, and functional, therefore are widely used in packaging field, but since they are difficult
Degradation, while plastics package brings benefit and convenience, waste also results in serious environmental pollution, threatens
People's health.Therefore, the packaging material of biological degredation plastic and Nantural non-toxic is increasingly becoming the heat of packaging field research
Point.
Starch is a kind of high-molecular compound of natural reproducible, from a wealth of sources, and reserves in nature are only second to fibre
Dimension element, it is safe and non-toxic and cheap, there is good biocompatibility and degradability.PBAT is that one kind biology can drop completely
The aromatic polyester of solution, it is that raw material passes through direct esterification or ester-interchange method that it, which is by adipic acid, terephthalic acid (TPA), 1,4-butanediol,
The three-element copolymerized ester being polymerized.However, keeping its degradation rate relatively slow due to the presence of PBT segment, and PBAT price
It is higher, limit the application of its market.Nano material has various excellent characteristics, is applied in high molecular polymer, Ke Yigai
Certain performances of kind polymer.Nano zine oxide has many advantages, such as nontoxic, inexpensive.The size of nanoparticle is smaller, can will divide
The matrix of dephasing and material combines better so that the compactness of composite material improves, such substrate can in intensity, just
Property, improved in terms of toughness, nano material can also play the role of improving material waterproofing.
But have not yet to see the phase using starch, PBAT and nano zine oxide for degradation material made of primary raw material
Close report.
Summary of the invention
The object of the present invention is to provide a kind of nano zine oxide enhancing tapioca/PBAT degradation material and its preparation sides
Method is film forming matrix by using tapioca, PBAT and nano zine oxide, adjusts the dosage of additive and auxiliary agent, make to be made
Edible package film have excellent performance and biodegradable, to meet the performance requirement of packaging material.
The present invention solves above-mentioned technical problem by using following technical solution:
Nano zine oxide of the present invention enhances tapioca/PBAT degradation material, is made of following raw materials in parts by weight:
10-30 parts of starch, 70-90 parts of PBAT, 3-12 parts of glycerol, 0.3-1.2 parts of release agent, 0-2 parts of nano zine oxide, laurel
It is 0.2-1.5 parts sour, 0.1-0.9 parts of compatilizer, wherein the dosage of methylene chloride be the mass ratio of its volume and PBAT be 4~
8mL:1g.
The starch refers to that cornstarch, tapioca, rice starch, pueraria starch, sweet potato starch, potato are formed sediment
One of powder, wheaten starch, green starch, pea starch, water caltrop starch, Lotus Root Starch, Chinese Water Chestnut Starch are several.
The release agent refers to polyethylene glycol 200, polyethylene glycol 400, Macrogol 600, polyethylene glycol-800, poly- second
One of glycol 1000 is several.
The compatilizer refers to that stearic acid, cinnamic acid, arachidic acid, myristic acid and citric acid are one such or two
The mixture of person.
Raw material optimum ratio of the present invention is as follows: 20 parts of tapioca, 80 parts of PBAT, and 6 parts of glycerol, polyethylene glycol 200
0.9 part, 1 part of nano zine oxide, 0.4 part of lauric acid, 0.5 part of arachidic acid, wherein the dosage of methylene chloride is its volume and PBAT
