Abstract

The invention discloses a foamed material, and applications thereof. The foamed material is prepared from graphene, polyvinyl chloride, ethylene propylene rubber, polyoxypropylene triol, caprylic / capric triglyceride, a metacrylic acid ester polymer, chlorinated paraffin, ceramic fiber, maleic anhydride, ethylene-ethyl acrylate copolymer, vinyl acetate ethylene copolymerization emulsion, triisopropanolamine, an adhesive, a dispersant, a tackifier, a cross-linking agent, a catalyst, a plasticizer, a flexibilizer, an foaming agent, a foaming conditioning agent, a foam stabilizer, a curing agent, a degradation agent, and a stabilizing agent. The foamed material is obtained via steps including mixing and extrusion. The foamed material can be applied in 3D printing, is degradable, can be degraded completely in 261 to 294 days; the sound reduction index ranges from 22.8 to 29.14dB, and the sound insulation effect of the foamed material is excellent.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of foam material preparation, and in particular relates to a foam material and its application. [0003] 【Background technique】 [0004] Foam material is also called porous material. It is made of resin as the main raw material and has countless micropores inside. It has the functions of light weight, heat insulation, shock resistance and corrosion resistance. It is widely used as packaging materials and car and ship shells. [0005] In 2004, Geim and Novoselov of the University of Manchester in the United Kingdom obtained independent two-dimensional graphene (Gra-phene, GN) crystals by stripping highly oriented graphite through tape, and graphene has become a research hotspot in the field of materials science. one. Graphene is actually a single atomic layer of graphite, which has a unique two-dimensional structure and excellent mechanical, thermodynamic, optical and electrical properties. [0006]...
