Nano composite canvas coating containing graphene

Abstract

The invention discloses a nano composite canvas coating containing graphene. The nano composite canvas coating containing graphene is characterized by comprising the following components in parts by weight: 2-4 parts of polyvinyl alcohol resin, 14-30 parts of film-forming polymer resin emulsion, 1-20 parts of nano calcium carbonate slurry, 23-39 parts of white filler, 4.9-6.9 parts of coating assistant, 20-30 parts of diluent water and 0.1-2 parts of graphene, wherein the part by weight of each component is 8-18 when the film-forming polymer resin emulsion is formed by more than two components, and the weight percent of nano calcium carbonate in the nano calcium carbonate slurry is 48-52%; the part by weight of each component is 5-20 when the white filler is formed by more than two components; the part by weight of each component is 0.25-4 when the coating assistant is formed by more than two components; the film-forming polymer resin emulsion is one or more out of a styrene-acrylic emulsion, a micron-scale pure acrylic resin emulsion and an ultraviolet self-cross linked pure acrylic emulsion; the viscosity of the nano calcium carbonate slurry is smaller than or equal to 800mPa.s; the PH value is 7.5-9.0; the mean grain size of the nano calcium carbonate is smaller than or equal to 60 nanometers.

Description

technical field [0001] The invention relates to a nano-composite canvas paint which can be applied on the surface of a canvas, in particular to a graphene-containing nano-composite canvas paint with electrical conductivity and good adhesion. Background technique [0002] Canvas is the most important carrier of paintings, and its use can be traced back to the Renaissance Venetian painters. The painter expresses his inspiration on the canvas in the form of color and pattern, and has created one masterpiece after another. The quality of the coating material used for painting and the quality of the coating process are the key to determining the expressiveness and the quality of the painting. The canvas coating material requires strong adhesion to the canvas, and has oil resistance and stretch resistance. Non-toxicity, no cracking, anti-aging and other characteristics, can make the canvas works intact after a long period of preservation, and leave them for future generations to ...
