Abstract

The invention discloses a PVC (polyvinyl chloride) yoga mat and a preparation method thereof, and the PVC yoga mat is prepared from the following raw materials in parts by weight: 30 to 80 parts of PVC paste resin, 10 to 50 parts of high polymerization degree PVC paste resin, 30 to 70 parts of filler, 10 to 50 parts of vinyl chloride-acrylate grafted copolymer, 2 to 15 parts of porous PVC, 80 to 120 parts of plasticizer, 2 to 8 parts of foaming agent and 1 to 4 parts of stabilizer. According to the PVC yoga mat, the adopted PVC paste resin material can be recycled and is good in environmental protection property, the rebound resilience can be improved by adding the high-polymerization-degree paste resin and the vinyl chloride-acrylate grafted copolymer, meanwhile, the precipitation of a plasticizer can be reduced by adopting the porous PVC, and the flexibility and rebound resilience of the PVC yoga mat are further enhanced. The PVC yoga mat provided by the invention has the advantages of high rebound resilience, high wear resistance, high flexibility and lasting rebound resilience and flexibility, accords with EN71-3 and CA65 environmental protection standards, and accords with national green development requirements.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to a PVC yoga mat and a preparation method thereof. Background technique [0002] In today's society, practicing yoga has become one of the fashionable sports. Long-term yoga practice can prevent diseases, effectively regulate the nervous system and endocrine system, and improve human health. Yoga mats are indispensable when doing yoga exercises. Yoga mats can effectively reduce the pain in contact with the ground. In addition to softness and good resilience, yoga mats should also have good anti-skid performance. , toughness and mechanical properties. At present, the materials of yoga mats are generally divided into rubber foam, TPE foam, PVC foam, EVA, latex mats, NBR mats, etc., but rubber is not recyclable and the environmental protection is not strong, so people turn their attention to PVC materials. The yoga mat made of PVC material is mainly mixed with fillers such as PVC, p...
