Traditional Chinese medicine antibacterial PU foaming shoe material with good moisture absorption performance and preparation method thereof

Abstract

The invention discloses a traditional Chinese medicine antibacterial PU foaming shoe material with good moisture absorption performance and a preparation method thereof. The material is prepared fromthe following raw materials in parts by weight: 80-90 parts of polyurethane, 10-14 parts of styrene-ethylene-butadiene-styrene block copolymer, 4-6 parts of polyethylene oxide, 4-6 parts of epoxidizedsoybean oil, 2-2.6 parts of fructus cnidii, 1.4-1.8 parts of dandelion, 2.4-3.6 parts of carboxymethyl cellulose, 1.8-2.2 parts of 4-methylbenzenesulfonyl hydrazine, 0.6-0.75 part of triethylene diamine, 0.08-0.1 part of triallyl isocyanurate, 5-9 parts of a filling material, 1.2-1.6 parts of zinc oxide, 2.5-4 parts of stearic acid and 1.5-2.7 parts of zinc stearate. The traditional Chinese medicine antibacterial PU foaming shoe material with the good moisture absorption performance is small in density and light in weight; the antibacterial rate is high, and the antibacterial performance is good; the tensile strength is high and the mechanical property is good; the resilience rate is high, the compression set rate is low, and the elasticity is good; the comprehensive performance is excellent, and durability and antibiosis are achieved.

Description

technical field [0001] The invention relates to the field of PU foam materials, in particular to a traditional Chinese medicine antibacterial PU foam shoe material with good hygroscopic performance and a preparation method thereof. Background technique [0002] With the rapid development of the footwear industry, the varieties of sole materials are increasingly diversified. The polyvinyl chloride and rubber solid soles that dominate the traditional footwear industry have been gradually replaced by the emerging rubber and plastic foam shoes. The main materials of foam soles generally include polyvinyl chloride (PVC), polyethylene (PE), styrene-butadiene-styrene copolymer (SBS), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA) )Wait. [0003] Polyurethane material is the abbreviation of polyurethane, the English name is polyurethane, it is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is ...

AI Technical Summary

Problems solved by technology

[0006] 1. Low density and good mechanical properties cannot be well taken into account, or due to poor foaming effect, the mechanical properties and other properties are greatly reduced, and the comprehensive properties such as strength are poor;

[0007] 2. The rebound rate is average, the compression permanent deformation is large, the elasticity is poor, and the permanent deformation is easy to occur during use;

[0008] 3. It does not have antibacterial properties, or uses silver antibacterial agents, which affects mechanical properties, etc., and is toxic, unhealthy, and does not have health care functions, and cannot meet the needs of consumers for diverse functions.
