Problems solved by technology

The invention uses an extractant to remove low-molecular-weight volatiles, and the extractant releases a low-boiling additive during the material melt blending process, which is similar to and compatible with odorous small molecules and can extract small odorous molecules in TPV materials. Molecular substances act, and then take them away by vacuuming to obtain TPV materials with low odor and low TVOC content; but this application technology cannot completely remove low-volatile substances in TPV, and there will be low-volatile substances in TPV as time goes on It escapes slowly and continues to endanger the surrounding environment. Therefore, it is necessary to adopt a new and effective method to decompose the low-volatile substances that TPV materials continuously and slowly escape during use, and the decomposed products are harmless substances, and at the same time, they can play a role in the surrounding environment. Sterilize, remove odors and eliminate low-volatility harmful substances released by other surrounding materials

Abstract

The invention discloses a low-odor TPV material with a sterilization function and a preparation method thereof. The TPV material is prepared from polypropylene, ethylene propylene diene terpolymer, thermoplastic elastomer, paraffin oil, cross-linking agent, TPV deodorant, coating lytic enzyme, nano photocatalyst, and antioxidant according to parts by weight. The TPV deodorant eliminates low molecular weight volatile matters in TPV, and releases low boiling point additive in melting and mixing of materials, is similar to and compatible with small molecules with odor, and can extract the small molecular substances with odor in the TPV material, and then the extracted small molecular substances with odor are taken away by a vacuum pumping method, so that a low-odor TPV material is obtained; and the coating lytic enzyme and nano photocatalyst decompose trace low volatility harmful gas generated by a material shaping part and low volatility harmful gas generated by surrounding environment of the part into harmless carbon dioxide and water, so that the TPV material has powerful functions of sterilizing, deodorizing, resisting mildew, resisting stain and self-cleaning, and purifying air.

Description

technical field [0001] The invention relates to the technical field of modification of thermoplastic elastomer materials, in particular to a TPV material with low odor and bactericidal function and a preparation method thereof. Background technique [0002] The polyolefin alloy thermoplastic elastomer material prepared by dynamic vulcanization technology—TPV is mainly composed of two parts, one part is plastic as the continuous phase, and the other is rubber as the dispersed phase, which presents a unique sea-island structure on the microcosm. In this way, TPV is both It has the excellent processing performance of plastics in the continuous phase and the unique high elasticity of vulcanized rubber particles as the dispersed phase. At the same time, the process flow of TPV is simple in manufacturing and application, the processing cycle is greatly shortened and the energy consumption is reduced. , so TPV is widely used, such as hoses for auto parts, auto dust covers, auto sea...
