Benefits of technology

This technology improves how we use carbon black (CB) instead of traditional materials like talcum powders for better shielding from electromagnetic waves or reducing heat transfer between different parts inside an article made up by multiple layers of material. Additionally, this innovation makes possible creation of special types that are more flexible than regular plastics while still maintain their effectiveness at cutting down unwanted rays.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the functionality or properties (such as impact strength) of colored polymer compositions used for various applications such as automobile parts. Current methods involve adding different chemicals into these materials during manufacturing processes which can be time-consuming and expensive due to their high cost compared with regular colors themselves.

Abstract

The invention discloses a thermochromic radiation-proof masterbatch and belongs to the field of high polymer materials. The thermochromic radiation-proof masterbatch is prepared from the following components in parts by weight: 60 to 80 parts of graphene, 20 to 30 parts of boron carbide, 20 to 30 parts of methyl methacrylate-butadiene-styrene terpolymer, 6 to 8 parts of ethylene-propylene-diene monomer, 3 to 4 parts of butyl benzyl phthalate, 3 to 4 parts of phenyl salicylate, 30 to 40 parts of ethylene-octylene copolymer, 20 to 30 parts of chitosan, 10 to 20 parts of aerosil, 6 to 8 parts ofhexamethyl disiloxane, 30 to 40 parts of styrene, 5 to 6 parts of butyl acrylate, 5 to 6 parts of coupling agents, 8 to 12 parts of sodium metaaluminate, 1.5 to 2 parts of polyvinyl alcohol and 0.3 to0.8 part of benzenediol. According to the thermochromic radiation-proof masterbatch, the problem that an existing masterbatch cannot effectively block radiation is solved.
