Description
Technical Field
The invention relates to the technical field of health-care insoles, in particular to an antibacterial sweat-absorbing health-care insole and a preparation method thereof.
Background
The beriberi, as a foot disease caused by fungal infection, often causes the foot to be extremely itchy and affects the work of people, and even causes secondary infection which seriously harms the health of human bodies. The insole is a necessity for life in direct and long-term contact with the foot, and its health care function has been continuously developed and explored in recent years.
Currently, in order to research the antibacterial health care function of insoles, the antibacterial medicine bag is mainly used as an insole interlayer to achieve the health care effect, and in recent years, research on polyurethane with antibacterial performance is also available.
Chinese patent CN201711358250.2, a chinese patent "a chinese herbal medicine insole for preventing and treating tinea pedis", discloses an antibacterial insole made by filling mixed Chinese herbal medicines through an intermediate layer, however, the filling of Chinese herbal medicines may make the insole feel hard and not soft, and uncomfortable to wear, and importantly, the volatilization of the traditional Chinese medicine components of the insole is fast, the time of the antibacterial and deodorant action of the traditional Chinese medicine is short, and the antibacterial action is not lasting.
Chinese patent No. 201710030120.X, "a polyurethane antibacterial and tinea pedis preventing insole", discloses a method for preparing an insole in which a polyurethane soft foam layer mixed with Chinese medicinal powder is used as an intermediate layer, but the soft foam used is a closed-cell polyurethane foam, and has poor air permeability, and the accumulation of sweat can cause discomfort of the foot after long-term wearing.
The selection of the efficient and durable antibacterial materials of the insoles and the development of a new process are worthy of further research and exploration.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides an antibacterial sweat-absorbing health-care insole and a preparation method thereof, wherein a super-hydrophilic technology is utilized to modify polyester knitted fabric, so that the polyester fabric is endowed with the capability of quickly absorbing sweat and guiding sweat, and a green plant artemisia apiacea extract is blended and crosslinked in a polyurethane reaction system, so that the material is endowed with a lasting biological antibacterial property; the combined structure enables the insole to absorb sweat rapidly and conduct the sweat to the lower layer of the perforated polyurethane foaming layer which is antibacterial for a long time, improves the comfort level of the insole, and has certain practical application value.
The scheme is realized by the following technical scheme:
a preparation method of an antibacterial sweat-absorbing health-care insole comprises the following steps:
s.1, coating polyester cloth by using a polyacrylate hydrophilic polymer solution at a certain padding rate, and shaping and drying by using a drying channel of drying equipment to obtain the treated polyester cloth; wherein, the polyacrylate hydrophilic polymer can be polyacrylic acid grafted maleic anhydride material;
s.2, adding the sweet wormwood herb extract into a first material tank filled with polyether polyol according to parts by weight, uniformly stirring the sweet wormwood herb extract and the polyether polyol at a certain temperature, adding an emulsifier, an amine ether foaming catalyst, an amine curing agent and a cross-linking agent to obtain a mixture, and continuously stirring the mixture for 2 hours at a certain temperature;
s.3, adding prefabricated diphenylmethane diisocyanate into the second material tank, and stirring at a certain temperature;
s.4, presetting the contents in the first material tank and the second material tank according to the corresponding weight of the mold, setting the injection amount according to different density requirements, stirring the mixture obtained by blanking and mixing the first material tank and the second material tank for 15-20 seconds by using a high-speed stirring head, uniformly pouring the mixture into a preheated mold, closing the mold under the condition of heat preservation, and opening the mold after 5-8 minutes to obtain cured polyurethane foam;
and S.5, cutting the processed polyester cloth obtained in the S.1, and performing hot-pressing lamination with the cured polyurethane foam obtained in the S.4 to obtain the antibacterial sweat-absorbing health-care insole.
Preferably, in S.1, the concentration of the polyacrylic acid modified hydrophilic polymer solution is 0.1-8%.
Preferably, in S.1, the padding rate is 60-200%.
Preferably, in S.1, the temperature of the drying tunnel is 80-140 ℃.
Preferably, in S.2, the stirring temperature of the sweet wormwood herb extract and the polyether polyol is 25 ℃.
Preferably, in s.2, the mixture consists of the following components in parts by weight: 1-5 parts of sweet wormwood herb extract, 100 parts of polyether polyol, 0.01-0.5 part of emulsifier, 2 parts of amine ether foaming catalyst, 0.2-2.0 parts of amine curing agent and 0.5-2.0 parts of cross-linking agent; the stirring temperature of the mixture was 40 ℃.
Preferably, in S.2, the emulsifier comprises silicone oil L-6900, the cross-linking agent is water, the amine ether foaming catalyst is one or more of 2- (2-dimethylaminoethoxy) ethanol (1-4) and bis- (dimethylaminoethyl) ether (1-3), and the amine curing agent is one or more of diethanolamine and triethanolamine.
