A kind of styrene-butadiene rubber/natural rubber/negative oxygen ion powder blended closed-cell secondary foaming material and preparation method thereof

Abstract

The invention relates to the technical field of foaming materials and provides a styrene-butadiene rubber / natural rubber / negative oxygen ion powder blended closed-pore secondary foaming material and a preparation method thereof.The negative oxygen ion powder of the styrene-butadiene rubber / natural rubber / negative oxygen ion powder blended closed-pore secondary foaming material can also effectively combine with a styrene-butadiene rubber raw material and natural rubber under the condition that the high biological activity is kept, the dispersion of the negative oxygen ion powder on rubber molecules is effectively improved, the original excellent physical properties of the rubber can be effectively kept, and sufficient negative oxygen ions can be also effectively and fully released.The concentration of the negative oxygen ions continuously released by a finished product prepared by the foaming material can be up to 1500 per cubic centimeter in a static state, the concentration of the continuously released negative oxygen ions can be up to 8000 per cubic centimeter in a dynamic state, the ambient air quality can be improved, the foaming material is beneficial to human body health, and the preparation method of the foaming material is simple in operation, easy to achieve and suitable for large-scale production and usage.

Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to a styrene-butadiene rubber / natural rubber / negative oxygen ion powder blended closed-cell secondary foaming material and a preparation method thereof. Background technique [0002] Styrene-butadiene rubber has become the mainstream rubber type because of its good elasticity, wear resistance, crack resistance, wet skid resistance and price advantages. With the maturity of domestic production technology, it has been widely used in various industries; and styrene-butadiene rubber The disadvantage is that the tear strength is low, and various chemical raw materials for preparation are easy to remain in its finished products. Various chemicals will continuously erode the living environment of human beings and creatures, and the living environment continues to deteriorate, especially water resources and air. The deterioration in quality is even more serious. [0003] In order...

Problems solved by technology

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, so as to enhance the application range of ecological health is an urgent need to solve in the field of foaming material technology important technical issues
