Novel graphene sponge

Abstract

The invention discloses a production process of novel graphene sponge. The production process comprises a material component structure, wherein the material component structure comprises a polyol component structure and an isocyanate component structure; the polyol component structure is formed by mixing high-activity polyether polyol, CASE polyether polyol, a crosslinking agent, a foaming agent,a catalyst and a foam stabilizer. According to the production process disclosed by the invention, graphene is mixed and added in the sponge-foaming process, graphene sponge has good electric-heat conductivity, the heat-conductivity coefficient is up to 5300W / mK, the static electricity and heat of a human body can be effectively conducted, and the calcium loss and memory deterioration of the humanbody can be prevented; the super-heat-conductivity coefficient is high, so that residual heat of the human body can be effectively conducted and the dryness heat can be prevented; simultaneously, thegraphene sponge also has good flame-retardant safe effect, and can replace the traditional flame-retardant agent sponge (the traditional flame-retardant agent contains a large amount of toxic substances of phosphorus, chlorine, bromine, antimony, aluminum and boron and the like) so as to be more environment-friendly and healthy.

Description

technical field [0001] The invention relates to the related field of sponges, in particular to a novel graphene sponge. Background technique [0002] Sponge is a porous material with good water absorption and can be used to clean items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. Alternatively, there are natural sponges made from spongy animals, and most natural sponges are used for body cleaning or painting. In addition, there are three types of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (highly absorbent material, no obvious pores), and polyester. [0003] However, existing sponges have the following problems: [0004] 1. The existing sponge does not have good electrical and thermal conductivity, and cannot better conduct static electricity and heat from the human body, resulting in the loss of calcium in the human body and memory loss; [0005] 2. The existing...
