Abstract

The invention discloses a graphene accessory for building external wall heat-insulation board and its preparation method. The graphene accessory is prepared from, by weight, 30 parts of graphene, 6-8parts of lead caprylate, 2-4 parts of glass fiber, 3-7 parts of acidified perlite, 1-3 parts of tungsten carbide, 1-3 parts of basalt fiber, 2-4 parts of polymethylvinylphenylsiloxane gum, 3-5 parts of magnesium oxide, 1-3 parts of cobalt aluminate, 3-5 parts of zinc oxide, 4-6 parts of manganese dioxide, 2-4 parts of vinyl acetate, 1-5 parts of nano-hydroxyapatite, and 2-4 parts of chrome. The graphene accessory for building external wall heat-insulation board and its preparation method are reasonable in component configuration and simple in preparation technique; through adding graphene andother conductive materials, every performance of the building external wall heat-insulation board, such as good heat insulation effect, high-temperature resistance and flame retarding performance, light mass, high intensity, waterproof, corrosive resistance, can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of carbon materials, in particular to a graphene auxiliary material used for building exterior wall insulation boards and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional crystal that is exfoliated from graphite material and composed of carbon atoms with only one layer of atomic thickness. In 2004, Andre Geim and Konstantin Novoselov, physicists at the University of Manchester, successfully separated graphene from graphite and confirmed that it can exist alone. Bell Prize in Physics. Graphene is both the thinnest material and the strongest, with a breaking strength 200 times stronger than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it can bear a cat wei...
