Problems solved by technology

The latex products produced by this natural latex are of good quality and have obviously improved mechanical properties, but their antibacterial properties need to be further improved
[0005] In order to further enhance the performance of natural latex products and expand its functions, it is proposed that graphene, a material with excellent optical, electrical, thermal and mechanical properties and huge specific surface area, can be added in the preparation of natural latex products. However, the existing technology In general, graphene is first compounded with natural latex, and after dispersion, a mixed solution of graphene natural latex is obtained, and then downstream products are produced, because natural latex has special requirements for conditions such as pH value and solid content , the pH value of graphene may cause the coagulation and demulsification of the latex, thereby making the latex invalid, and the natural latex has a certain viscosity, which is not conducive to the dispersion of graphene in the latex
