Polyurethane yoga mat and preparation method thereof

Abstract

The invention relates to the technical field of polyurethane material preparation, in particular to a polyurethane yoga mat and a preparation method thereof. The polyurethane yoga mat is prepared from a component A and a component B in a weight ratio of (1.8-2.2): 1, wherein the component A is prepared from the following raw materials in parts by weight: 90 to 100 parts of polyether polyol, 0.5 to 0.8 part of an anti-aging additive, 0.4 to 0.6 part of a foam regulating agent, 2 to 3 parts of deionized water, 0.4 to 0.6 part of an organic silicon surfactant, 0.6 to 0.8 part of a compound catalyst and 0.5 to 0.7 part of polyhexamethylene guanidine hydrochloride; and the component B is prepared from modified isocyanate and an opening agent which accounts for 4 to 10 percent of the weight of the modified isocyanate. The polyurethane yoga mat prepared by the preparation method disclosed by the invention not only has better mechanical properties, but also has good antibacterial, mildew-proof and anti-aging properties; and the service life of the polyurethane yoga mat is effectively prolonged, and the grade of the polyurethane yoga mat is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of yoga mat preparation, in particular to a polyurethane yoga mat and a preparation method thereof. Background technique [0002] Most of the yoga mats on the market today are mainly made of rubber, plastic and chemical fiber, which are renewable and have a low recycling rate. They not only have technical problems such as large environmental pollution and difficult recycling, but also have technical problems such as large pollution in recycling and processing. Take the rubber yoga mat as an example. First, it is not only expensive, but also in terms of the production equipment and the material itself. The high equipment price and material price determine the high cost of the rubber yoga mat. Second, the smell is strong, and the rubber itself It has a strong smell, which is very inconvenient for daily skin application. [0003] However, the polyurethane yoga mat prepared by foaming polyurethane material can ...

AI Technical Summary

Problems solved by technology

[0004] First of all, the antibacterial, anti-aging and anti-mildew properties of polyurethane yoga mats are relatively poor. During long-term use, some bacteria or microorganisms will grow on the surface of polyurethane yoga mats, which will affect the service life of polyurethane yoga mats to a certain extent.

[0005] Secondly, when the polyurethane yoga mat is affected by factors such as light and heat for a long time, it will cause damage to its body structure to varying degrees, resulting in yellowing of the polyurethane yoga mat.

[0006] In addition, in the process of preparing polyurethane yoga mats, foaming agents (such as water and other substances) need to be used, and traditional silicone surfactants are used as foam stabilizers, but only relying on such foam stabilizers, the foam stabilization effect It is not particularly ideal, and the quality of foaming is poor, which will have a negative impact on the quality of polyurethane yoga mats
