Problems solved by technology

Yet so far, also do not have a set of practicable methods to make consumers completely get rid of the troubles of wet feet, foot odor, and diseases such as beriberi caused thereby
Although almost every manufacturer or seller of footwear claims that their products are "antibacterial and deodorizing", due to the lack of insole materials with corresponding functions, the promise to consumers is exaggerated after all.

Abstract

The invention discloses a hydrogen bonding adsorption type polyurethane foam material and a preparation method thereof. A multiple hydrogen bond type polyurethane macromolecule long chain containing special chain knots is designed, the material has an adsorption characteristics applicable for the environment for water or moisture, the material has a desorption capacity, reducing regeneration function repeatability is realized, and a shoe pad is manufactured after the polymer is processed into a pore-open foam material, the perforated structure of the foam enables moisture or sweat generated byfeet of people to be of freely diffused passages, the inner wall of holes are of a hydrogen bonding adsorption effect, moisture or sweat can be adsorbed and accommodated, the dry and comfortable environment inside the shoe can be maintained, but excessive adsorption cannot be caused. The shoe pad manufactured by the material has circulating regeneration functions of moisture adsorption and desorption, and has effective moisture absorption and sweat releasing effects. The manufactured shoe pad has the advantages of baby diapers, and also can be repeatedly regenerated and reduced, so that lasting dry and comfortable environment is realized when the shoe pad is repeatedly used.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to a hydrogen bond adsorption type polyurethane foam material and a preparation method thereof. Background technique [0002] Keeping the inside of the shoes dry and free from wet feet is a matter of utmost concern to every footwear consumer. Yet up to now, also do not have a set of practical method to make consumers get rid of wet feet, foot odor, and the puzzlement of diseases such as beriberi caused thereby. Although almost every manufacturer or seller of footwear claims that their products are "antibacterial and deodorizing", due to the lack of insole materials with corresponding functions, the promise to consumers is exaggerated after all. [0003] Whether the shoes are "antibacterial and deodorant" during wearing, the decisive factor is the degree of humidity in the microenvironment inside the shoes. Since the secretion capacity of the sweat glands of each person's...
