Plastics, rubber, and rubber products containing tourmaline components and tender shale (negative oxygen ion powder) produced according to the aforementioned technology can be widely used in sporting goods, medical protective gear, dining utensils, office supplies, automotive interiors, decorations, etc. Materials and other products, when people use and touch such products, these products will exert the characteristics of tourmaline and tender shale (negative oxygen ion characteristics), can purify the surrounding environment and water quality, release negative oxygen ions, stimulate cell activity, and promote plant growth. Growth and development, prevention of electromagnetic radiation, etc., make people benefit from it. However, due to the material differences between rubber materials and tourmaline powder and tender shale, and tourmaline powder and tender shale also have high biological activity, for foaming materials It is difficult to say that the poor dispersion after processing and integration is difficult. If tourmaline powder and tender shale cannot be effectively and evenly dispersed in rubber molecules to form clusters, it will not only affect the quality of rubber products, but also cannot fully release a sufficient amount of negative energy. Oxygen ions cannot give full play to the effect of air energy negative oxygen ion powder, and the concentration of negative oxygen ions released by the product cannot reach 200-400 per cubic centimeter in static state and 400-1000 per cubic centimeter in dynamic state, and there is no improvement The air quality of the surrounding environment and the original intention of being beneficial to physical and mental health, therefore, how to improve the dispersion of negative oxygen ion powder in rubber, reduce costs, and improve the comprehensive physical properties of products, thereby enhancing the ecological health of rubber products is the current foaming material technology. Important technical issues that urgently need to be solved in the field
