The application of the water-soluble chitosan combination agent includes dispersing the water-soluble chitosan combination agent in water to form a water solution of the chitosan combination agent, and applying the water solution of the chitosan combination agent to the fields about air purification, bacteriostasis, moisturizing, dust control, freshness keeping, water purification, cosmetics, food and the like.
Description
Technical field
The present invention relates to a kind of agent of shitosan water-soluble combination and its application in fields such as purification of air, antibacterial, moisturizing, dust-proof, fresh-keeping, purification of water quality, cosmetics and food.
Background technology
Shitosan, also known as chitosan, is the nature uniquely natural activity polysaccharide fiber with cation positive charge.Shitosan is that the chitin being widely present in the plant cell wall such as the animal such as shrimp, Eriocheir sinensiss shell and mushroom, algae by nature is obtained through deacetylation, and chemical name is Chitosan (1-4) -2- amino-B-D glucoses.Shitosan has that cation positive charge, big molecular weight, higher viscosity, good biocompatibility, asepsis environment-protecting edibility, broad spectrum antibacterial, biodegradable, heavy metal ion be sequestering, film forming into characteristics such as fibers, there is good application prospect in fields such as environmental conservation, food, medical and health, agricultural, industry, animal husbandry, daily-use chemical industry, chemical analyses, biological engineering.
Shitosan is water insoluble, though deacetylation higher than 95% shitosan also can only in case of heating oligodynamical in water, the shitosan amount of dissolving does not also far reach the requirement for using.The characteristics of shitosan is water insoluble greatly limit the effective exploitation application of shitosan.At present, the use of shitosan is typically employed under conditions of heating, during shitosan is slowly added into into the acetic acid of high concentration or salt aqueous acid, long agitation forms shitosan-acetic acid or shitosan-aqueous hydrochloric acid solution, the shitosan acidic aqueous solution has stronger acid and corrosivity, there is larger contaminative and destructiveness to human body, animals and plants and surrounding enviroment, the use range and using effect of shitosan is greatly limited.Additionally, the preparation method of the chitosan aqueous solution requires that equipment has resistance to gentle corrosion resistant feature, need to consume the more energy, put into production use high cost；Meanwhile, easily there is aggregation sedimentation and cause performance to be remarkably decreased in the chitosan aqueous solution for preparing, cause aqueous products Acceptable life shorter after placing a period of time；Additionally, preparing chitosan aqueous solution also adds additional the costs such as the storage and transport of product.
Therefore, the use cost that fully reduce shitosan and the using effect for lifting shitosan, a kind of effective manner is to find to promote shitosan rapidly-soluble hydrotropy material in water, and the hydrotropy material should have the characteristics such as relatively low cost, nontoxic, environmental protection.Shitosan combination agent is formed after shitosan hydrotropy material is combined with shitosan, the combination agent can for a long time place and qualitative change does not occur, and while shitosan service life is lifted, also a saving the costs such as the storage and transport of shitosan product；In addition, the shitosan combination agent formed after being combined with shitosan by shitosan hydrotropy material can quickly be dissolved in the water at normal temperatures and pressures and form chitosan aqueous solution, the input cost of saving equipment, low-energy consumption is dropped, the scene and practice of construction for being easy to shitosan uses, and can greatly lift the range of application and using effect of shitosan.
