Abstract

The invention provides a masterbatch for a graphene anticorrosive coating and a preparation method of the masterbatch. The preparation method comprises the following steps: carrying out depth etchingon rubber powder particles by using laser for improving porosity of the rubber powder particles; then filling graphene into holes of a porous rubber powder material for carrying out high-speed stirring, enabling the porous rubber powder to effectively adsorb and carry graphene and finally obtaining the masterbatch. The prepared masterbatch is added into a waterborne resin coating for reacting withwater and quickly dispersing, and a continuous film is formed inside the coating, so that the graphene is driven to be uniformly dispersed into the coating, and further the problem that the grapheneis easy to overlap and aggregate in the application of anticorrosive coatings is effectively solved. Furthermore, porous emulsion powder particles are used as a carrier, has good compatiblity with thecoating and does not contain any impurity components; besides, the graphene anticorrosive masterbatch prepared by the method, disclosed by the invention, has the advantages of convenience in storage,no environmental pollution and remarkable market application value.

Description

technical field [0001] The invention relates to the field of graphene materials, in particular to a masterbatch for graphene anti-corrosion coatings and a preparation method. Background technique [0002] Anti-corrosion coatings are widely used in modern industry, transportation, energy, marine engineering and other departments. According to the corrosion resistance of the coating film and the use requirements, it is usually divided into two types: conventional type and heavy anti-corrosion type. At present, the market size of my country's anti-corrosion coatings ranks second only to architectural coatings. According to Qianzhan.com, the total output of anti-corrosion coatings in my country will reach about 6 million tons by 2017, and the total output of anti-corrosion coatings in my country will reach about 6.8 million tons by 2018. Among them, heavy-duty anti-corrosion coatings have the fastest growth rate and have promising development prospects. Compared with conventi...
