Abstract

The invention discloses a preparation method of a moisture-absorbing, antibacterial and wash-free insole coating of oyster shells, belonging to the technical field of shoe material preparation. Mixing and stirring sodium alginate, oyster shell powder, chitosan fiber, photocatalyst, water and the like according to a certain proportion, and stirring until a solution becomes a suspension to obtain slurry; the slurry is evenly coated on the surface of the prepared insole, and then the insole is put into a drying oven for baking, dehydrated and dried, taken out and cooled to obtain the moisture-absorbing, antibacterial and no-clean insole coating. After the insole prepared by the invention is used for a period of time, a consumer only needs to put the insole under the sunlight for airing for a period of time, and then the insole can play the roles of antibiosis, deodorization and self-cleaning, and does not need to wash with water, thereby saving resources and labor force and effectively ensuring the cleanness and sanitation of the sole of a foot of the user.

Description

Oyster shell moisture-absorbing, antibacterial and washing-free insole coating and preparation method thereof
Technical Field
The invention belongs to the technical field of shoe material preparation, and particularly relates to a preparation method of a moisture-absorbing, antibacterial and wash-free insole coating of oyster shells.
Background
Shoes are necessities of people's life at present, and due to daily outdoor activities, a large amount of sweat can be discharged from soles of the feet to cause a damp environment in the shoes. Because the space in the shoes is limited, bacteria and fungi are favorably bred, and peculiar smell and foot diseases caused by the limited space become a great problem which troubles the life of people. The insole is an important component of the shoe, and has important significance for ensuring the sole health of consumers if the insole has good functions of moisture absorption, antibiosis, deodorization and the like.
Chitosan is a basic polysaccharide, and the derivative thereof has the advantages of no toxicity, biodegradability, good biocompatibility, adsorptivity, adhesiveness, reactivity, safety, broad-spectrum antibacterial property and the like. It has wide application in textile, paper making, food, medicine and chemical industry, etc. A great number of documents report that chitosan has broad-spectrum antibacterial performance and has better inhibitory effect on various bacteria, fungi and even some viruses. Therefore, if chitosan can be added into the insole, the insole has excellent antibacterial effect.
Oyster shell and egg shell are a pure natural biomass material, and the main component is calcium carbonate. Due to the characteristics of hierarchical and porous structures, the composite material is widely applied to the fields of water treatment, ecological coating, papermaking, drying agents and the like. It is useful in the field of moisture absorption and the like because of its excellent adsorption property. On the other hand, the method can change waste into valuable, and makes positive contribution to the healthy and sustainable development of the marine shellfish breeding industry and the poultry breeding industry.
The photocatalyst is a generic name of a semiconductor photocatalyst represented by nano titanium dioxide. The catalyst is coated on the surface of a base material, generates active oxygen species under the action of ultraviolet light and visible light, can generate catalysis, decomposition and other effects with organic matters, toxic and harmful gases, bacteria, fungi, viruses and the like, and has important application in the fields of air purification, sewage treatment, deodorization and the like. The method is used for preparing the self-cleaning, no-washing and antibacterial insoles in the field of insoles and has important value.
Disclosure of Invention
The invention provides a preparation method of a moisture-absorbing, antibacterial and wash-free insole coating of oyster shells. The insole coating prepared by the invention has the functions of antibiosis, deodorization and self-cleaning, and can effectively ensure the cleanness and sanitation of the sole of a user.
In order to achieve the purpose, the invention adopts the following technical scheme:
a moisture-absorbing, antibacterial and wash-free insole coating of oyster shells is prepared from the following components in parts by weight:

1 to 50 parts of oyster shell powder,
1-10 parts of chitosan fiber,
0.1 to 5 portions of photocatalyst,
50-70 parts of pure water.
The insole is made of the following materials: EVA, sponge, TPR, silica gel, latex, cloth, leather, CPU, non-woven fabrics.
The preparation method of the oyster shell moisture-absorbing, antibacterial and no-clean insole coating comprises the following specific steps:
(1) weighing sodium alginate, oyster shell powder, water-soluble chitosan fiber and photocatalyst according to a certain proportion, sequentially adding into pure water, and strongly stirring at room temperature for 20 minutes to obtain a suspension;
(2) and uniformly coating the suspension on the surface of the prepared insole, heating in a 60 ℃ oven for 1 hour, taking out and cooling to obtain the target product.
Compared with the prior art, the invention has the beneficial effects that:
(1) the oyster shell material has wide raw material source, does not generate any pollution, can realize the recycling of biological waste, changes waste into valuable, and promotes the benign development of related industries;
(2) the photocatalyst is added to make the insole have the functions of self-cleaning, sterilizing and deodorizing, washing with water is not needed, and resources and labor are saved.
(3) The method is simple, is finished in a water phase system, has no toxicity and danger to operators, is environment-friendly, has high industrialization degree and has strong application prospect.
