Problems solved by technology

[0004] However, in the prior art, there is a lack of a TPE material more suitable for sex toys
Sexy toys have a high degree of intimate contact with the human body, and require better antibacterial performance, but adding antibacterial agents to TPE materials will easily cause the elasticity of TPE materials to decrease, while sex toys have higher requirements on the elasticity of materials, which is solid in the prior art. The TPE material is difficult to meet the requirements

Abstract

The invention relates to the field of modified TPE, in particular to an antibacterial TPE ultra-soft material and a preparation method and application thereof. The antibacterial TPE ultra-soft material is prepared from 15-25% of SEPS, 73 to 84% of 100N base oil and 1-3% of an antibacterial auxiliary agent by mixing. The TPE material obtained through the formula has characteristics of sufficient elasticity, and compared to the addition of other types of mineral oil, the base material can be compounded with a certain amount of the antibacterial auxiliary agent so as to be subjected to melt extrusion without mechanical property reduction; the preparation method of the antibacterial TPE ultra-soft material comprises the steps of raw material stirring, melt extrusion and grain-sized dicing, andthe method can ensure that the microstructure of the antibacterial auxiliary agent is not damaged and plays a role for a long time; an antibacterial sex toy is obtained through injection molding of the TPE ultra-soft material, and the product is sufficient in elasticity and good in antibacterial performance and has good market value.

Description

technical field [0001] The invention relates to the field of modified TPE, more specifically, it relates to an antibacterial TPE supersoft material, its preparation method and application. Background technique [0002] TPE material, the English name is Thermoplastic Elastomer, also known as thermoplastic high elastic plastic body, or thermoplastic elastomer, which is a kind of rubber with high elasticity, high strength, high resilience, and has the characteristics of injection molding. Materials are generally used in toys, sports equipment and other items. TPE material is environmentally friendly, non-toxic and safe, has excellent colorability, fatigue resistance and temperature resistance, and has a soft touch, excellent processing performance, and does not require vulcanization. Since Bayer first prepared thermoplastic polyurethane (TPU) in 1958, TPE has developed rapidly, especially after the advent of styrene-based thermoplastic elastomers in 1963, the theory of prepara...
