Modified plastic based on few-layer graphene and preparation method of modified plastic

Abstract

The invention provides modified plastic based on few-layer graphene and a preparation method of the modified plastic. The modified plastic is prepared from: 1000 parts of plastic, 3 to 8 parts of polydimethylsiloxane, 5 to 35 parts of few-layer graphene powder, 5 to 25 parts of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane, 25 to 70 parts of methanol and 4 to 8 parts of softened water. The PP modified plastic sample prepared by the invention is injected into an electric fan shell for an aging comparison test, it is verified that the new material can effectively utilize the shell for heat conduction and dissipation, and the temperature rise of the internal structure can be reduced by 10% through one-hour test; after the prepared modified PE plastic is molded into different products, the antibacterial property of the modified PE plastic can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of graphene application, in particular to a modified plastic based on few-layer graphene and a preparation method thereof. Background technique [0002] PP plastic (polypropylene) has good impact resistance, insulation and mechanical properties, high melting point and low temperature resistance, so it can be widely used in consumer products and industrial products. Especially its high dielectric coefficient and high breakdown voltage are very suitable for making heated electrical insulation products and electrical enclosures or accessories. However, due to its relatively low thermal conductivity, when it is applied to a heat-generating product shell, the temperature of the internal structure of the product often rises too high because the product cannot effectively dissipate heat through conduction. Household appliances on the market, such as electric fans, generally use PP plastic as the shell material to ...

Problems solved by technology

However, due to its relatively low thermal conductivity, when it is applied to the shell of a product that generates heat, the temperature of the internal structure of the product often rises too high because the product cannot effectively dissipate heat through conduction.

Household appliances on the market, such as electric fans, generally use PP plastic as the shell material to achieve the purpose of insulation and isolation. However, if the internal temperature rise is too high, the working environment of the power supply will deteriorate, which will reduce energy efficiency and even affect the effective working life of the product.
