Abstract

The invention discloses a PPC yoga mat and a preparation method thereof, and belongs to the technical field of yoga mats, wherein the PPC yoga mat sequentially comprises a base cloth layer and a foaming layer from bottom to top, and the foaming layer comprises, by weight, 80-120 parts of polypropylene carbonate polyol, 10-30 parts of ethylene-vinyl acetate copolymer, 10-20 parts of foaming agent, 8.3-9 parts of deodorant, 3.9-8 parts of calcium carbonate and 2-4 parts of zinc oxide. According to the invention, the physical adsorption type deodorant and the coupling type deodorant are used in a compounding way, so that the deodorizing effect of the deodorant can be enhanced, and the problem that the peculiar smell is desorbed and released again after the physical adsorption type deodorant is adsorbed to be saturated can be avoided. In addition, the foam holes can be ensured to be uniform and the yoga mat surface is endowed with high anti-slip performance by controlling the foaming temperature and time. Moreover, through the surface suppression antiskid line at the foaming layer to combine the microporous structure of PPC foaming layer, can show the antiskid performance that promotes yoga mat.

Description

PPC yoga mat and preparation method thereof Technical Field The invention relates to the technical field of yoga mats, in particular to a PPC yoga mat and a preparation method thereof. Background Yoga exercise has become a widely popular exercise way in the society today, and an essential auxiliary device in yoga training is a yoga mat. The yoga mat in the existing market is various in material, wherein the PPC yoga mat is a novel yoga mat product taking polypropylene carbonate polyol as a raw material, has good flexibility and rebound resilience, and has the advantage of good buffering and damping effects, and meanwhile, the mat body can realize excellent anti-skidding performance after surface texture optimization. However, polypropylene carbonate polyols use propylene oxide during production, which tends to give rise to significant chemical odors when left in yoga mats, and consumers can feel uncomfortable when they contact the yoga mats or during exercise for a long period of time. In order to solve the problems, the prior art adds the deodorant into the raw materials for preparing the yoga mat, but the deodorant is single in type and unsatisfactory in deodorizing effect, and the compatibility of the deodorant and a PPC system is poor, so that the PPC yoga mat cannot be simultaneously considered to have low odor and high anti-skid performance. Disclosure of Invention The invention aims to provide a PPC yoga mat and a preparation method thereof, and aims to solve the problems that the existing PPC yoga mat is not ideal in deodorizing effect and cannot be enabled to be low in odor and high in anti-skid performance. The PPC yoga mat comprises a base cloth layer and a foaming layer in sequence from bottom to top, wherein the foaming layer comprises, by weight, 80-120 parts of polypropylene carbonate polyol, 10-30 parts of ethylene-vinyl acetate copolymer, 10-20 parts of foaming agent, 8.3-9 parts of deodorant, 3.9-8 parts of calcium carbonate and 2-4 parts of zinc oxide, and the deodorant is a mixture of coupling deodorant and physical adsorption deodorant. Optionally, the ratio of the coupling type deodorant to the physical adsorption type deodorant is (0.3-0.5) 8. Optionally, the coupling deodorant is at least one of polyethylene diamine, diethanolamine and polyethyleneimine.
