Description

A kind of preparation method of the synthesized thin film of antibacterial degradable
Technical field
The present invention relates to membrane technology and preparation fields, and in particular to a kind of preparation side of the synthesized thin film of antibacterial degradable Method.
Background technology
Environmental protection, economizing on resources has become the basic strategy that sustainable development is realized in countries in the world.Once for the mankind with Carry out very big easily environmental pollution caused by plastic products and increasingly disputed on extensively to the consumption of the energy.Due to China Population base is huge, economy rapid growth, and the production and consumption amount of non-degradable plastics has resulted in serious ring in explosive growth Border is polluted and substantial amounts of energy consumption.The nutriments such as food storage during easily be subject to environment in microorganism polluted, In turn result in the rotten and rotten of food.In addition, the ultraviolet light and free radical in environment can also cause the oxidation of lipid material, break It goes bad its taste or even generates some pathogenic, carcinogenic chemical compositions.Therefore, in order to extend food, drug when the preservation of substances Between, meet green chemical concept, the new packaging material for researching and developing antibacterial degradable is significant.Therefore, in order to more The environment and resource problem that good solution becomes increasingly complex, people start gradually to be transferred to sight on degradable material.
At present, the hot spot of the degradation material of people's research concentrates on cellulose, lignin, starch, chitin, shell and gathers Sugar, other polysaccharide, protein and natural rubber etc., but the utilization of these materials is lacked be subject to cost, actual use performance Fall into and be restricted, the shortcomings of mechanical strength is low for example, chitosan is subject to, brittleness is big, moisture-proof acid resistance suitable application area narrow.
Chitosan quaternary ammonium salt is chitosan derivatives, and water solubility can preferably play chitosan better than chitosan The effect of.Chitosan quaternary ammonium salt has good antibiotic property, film forming, Cation adsorption, moisture absorbability and moisture retentivity, flocculability, anti- The performances such as static behaviour.Containing substances such as brass, aromatic acid and esters in propolis, there is very strong antibacterial, sterilizing ability；In addition, bee Glue contains antioxidant content, has extremely strong oxidation resistance, the oxidation of functional components in fruits and vegetables can be effectively prevented, so as to carry The quality of high food.Containing flavonoids, phenol and volatile compound and hydrogen peroxide in honey, there is excellent antibacterial Effect.Nano-meter SiO_22Also known as ultra-fine white carbon black is a kind of nontoxic, tasteless, pollution-free and with nano-meter characteristic and certain antibacterial The chemical material of property；Nano-meter SiO_22With other polymers are compound can not only enhance its mechanical property, while also using silicon oxygen bond To CO2And O2Absorption, dissolving, diffusion, release action, the exchange capacity of two kinds of gas inside and outside adjusting film, so as to inhibit exhaling for fruits and vegetables Intensity and water loss are inhaled, is haved the function that preserving fruit and vegetable utilizing.
The content of the invention
In view of the defects existing in the prior art, the present invention provides a kind of preparation side of the synthesized thin film of antibacterial degradable Method, composite membrane prepared by this method have higher mechanical strength and bacteriostasis property, are avoided that in food packaging, preservation process Microbial growth spoilage problem improves the service life of film.
A kind of preparation method of the synthesized thin film of antibacterial degradable, comprises the steps of：
