Abstract

The invention relates to the technical field of deodorizing materials, and provides a modified fine-pore silica-alumina gel deodorizing material which is prepared by loading ascorbic acid on the surfaces of fine-pore silica-alumina gel particles in order to solve the problems of weak deodorizing effect and short deodorizing time of traditional deodorizing insoles. The ascorbic acid is loaded on the fine-pore silica-alumina gel particles to achieve physical adsorption and chemical adsorption dual deodorization effects, the fine-pore silica-alumina gel particles have a physical adsorption effecton sweat, substances such as ammonia contained in the sweat are reduced through the reversible oxidation-reduction effect of the ascorbic acid, generation of odor molecules is inhibited, the modifiedfine-pore silica-alumina gel deodorization material can be used as a filling material to be applied to polyurethane foam insoles, and the obtained polyurethane foam insoles have long-acting sweat absorption and deodorization performance.

Description

technical field [0001] The invention relates to the technical field of deodorizing materials, in particular to a modified fine-pore silica-alumina gel deodorizing material, a polyurethane foam insole and a preparation method thereof. Background technique [0002] Insole is a shoe lining that is made into the shape of the sole and attached to the shoe. The insole is widely used in the shoe industry, health care, and special functions; it is generally divided into two models: the shoe industry application type shoe factory application type and the market commodity type. The insoles used in the shoe industry are mainly used to match the outsole and midsole of the shoe to make a corresponding shape; make a size board according to the last board or panel, and make the corresponding shape. [0003] Traditional insoles are mainly made of bamboo shoot shells and cotton cloth. The bamboo shoot shells are cut to the size of the soles, then flattened with heavy objects, and the surface...
