Abstract
The method of a kind of sodium alginate-silk gum mixture modified natural emulsion, step is: the preparation of (1) sodium alginate-sericin mixture: be dissolved in water by sodium alginate, silk gum is added in solution, mix postlyophilization, then heat 30min at lyophilized products being placed in 30 DEG C, obtain sodium alginate-silk gum covalent complex for subsequent use; (2) preparation of modified milk glued membrane: preparation sodium alginate-silk gum covalent complex aqueous solution, with natural milk gelatin mixing and stirring, carries out latex film sulfidizing, after emulsion-stabilizing bubble-free, at 70 DEG C, pours into a mould film forming, obtain modified milk glued membrane.Natural emulsion prepared by the present invention possesses ageing resistance, antiallergic property.
Description
Technical field
The present invention relates to a kind of method of modifying of natural emulsion, the method for particularly a kind of sodium alginate-silk gum mixture modified natural emulsion, belong to natural macromolecular material manufacture field.
technical background
Natural emulsion is a kind of through biosynthesizing, reproducible natural resources, is widely used in the products such as medical catheter, medical gloves and condom because of the over-all properties of excellence.But natural emulsion is because containing unsaturated double-bond, and make its oil-proofness, ageing resistance poor, micro-water-soluble protein wherein causes human allergy to react.
Summary of the invention
The object of this invention is to provide a kind of method of modifying of natural emulsion preparing ageing resistance, antiallergic property.
For realizing above object, the method for a kind of sodium alginate of the present invention-silk gum mixture modified natural emulsion, step is:
(1) preparation of sodium alginate-sericin mixture: sodium alginate is dissolved in water, silk gum is added in solution, mix postlyophilization, at then lyophilized products being placed in 30 DEG C, heat 30min, obtain sodium alginate-silk gum covalent complex for subsequent use;
(2) preparation of modified milk glued membrane: preparation sodium alginate-silk gum covalent complex aqueous solution, with natural milk gelatin mixing and stirring, carries out latex film sulfidizing, after emulsion-stabilizing bubble-free, at 70 DEG C, pours into a mould film forming, obtain modified milk glued membrane.
Preferably, the mass ratio of sodium alginate and silk gum is 5:1-20:1; The add-on of sodium alginate-silk gum covalent complex is the 1%-2% of natural emulsion quality.
The beneficial effect that the present invention produces is that sodium alginate has good biocompatibility and biodegradability, has good affinity with human body skin.Silk gum has good biocompatibility, oxidation-resistance, bacteria resistance.Utilize various active group in sodium alginate and sericin molecule to the protein cross sex change in natural emulsion, reduce water-soluble protein spillage, give modified milk glued membrane antiallergic property.
