Natural aromatic environment-friendly EVA composite foam material and its preparation method and application

Abstract

The invention relates to the technical field of EVA composite materials, and specifically discloses a natural aromatic and environment-friendly EVA composite foam material, which is prepared from the following components in parts by weight: 80-100 parts of rubber-plastic base material, 4-8 parts of hair Foaming agent, 0.5-1 part of cross-linking agent, 0.5-0.8 part of mineral oil, 0.5-1 part of stearic acid and 20-40 parts of modified lavender particles, the rubber-plastic base material contains 40%-100 % EVA. The present invention adopts modified lavender particles, which can effectively control the volatilization of lavender aroma components, achieve lasting aroma effect, and at the same time can enhance the antibacterial performance and deodorization of foaming materials and products, and has the advantages of deodorization, ventilation, refreshing, incense and fragrance. It has the advantages of repelling insects, can improve the utilization rate of lavender, reduce waste and environmental pollution, and is green and environmentally friendly. It is suitable for daily necessities and sports equipment such as shoe soles, insoles, yoga mats, and crawling mats.
