Graphene natural rubber antibacterial children crawling composite material and preparation method thereof

Abstract

The invention provides a graphene natural rubber antibacterial children crawling composite material and a preparation method thereof. The graphene natural rubber antibacterial children crawling composite material is prepared from the following raw materials in parts by weight: 70-100 parts of natural rubber, 18-25 parts of ethylene propylene diene monomer rubber, 3-6 parts of a nano active medium,0.5-10 part of graphene, 5-10 parts of zinc chloride, 3-6 parts of a vulcanizing activator, 0.4-2 part of a surfactant, 0.8-2.5 parts of an odorless cross-linking agent and 2.5-5 parts of a foaming agent. The preparation method of the composite material comprises the following steps: heating graphene treated by a surfactant, sequentially adding natural rubber and ethylene propylene diene monomer,and mixing in a mixing mill to obtain mixed raw rubber; and adding an odorless cross-linking agent, a foaming agent, zinc oxide, a vulcanizing activator and a nano active medium into the mixed raw rubber, and carrying out mixing, vulcanizing and cross-linking again, so as to obtain the graphene natural rubber antibacterial children crawling composite material. The composite material has the advantages of being high in elasticity, good in wear resistance, antibacterial, non-toxic, unlikely to deform, easy to clean and the like, and therefore, the use effect is better.

Description

technical field [0001] The invention belongs to the technical field of rubber-based composite materials, and in particular relates to a graphene natural rubber antibacterial children's crawling composite material and a preparation method thereof. Background technique [0002] Graphene is a sp 2 A new material in which hybrid-connected carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. As a reinforcing material for rubber, a small amount of filling can greatly improve The mechanical properties of rubber, and can show its good electrical and thermal properties, is a very ideal rubber nanomaterial. [0003] Rubber material is one of the indispensable and alternative key materials in the current national economy and high-tech fields, and i...

Problems solved by technology

Traditional crawling products are generally blankets and quilts, but these products have many problems: first, they are heavy and not easy to carry; second, they are easy to get dirty, and it takes time and effort to clean them;
