Abstract

The present invention involves the field of anticorrosive coatings, which provides a graphene -based high -solid high -solid -based epoxy anticorrosive coating and its production method to solve the poor anticorrosive coating performance of existing technologies, not environmental protection, and graphene difficult to stabilize the stability in the coatings.The problem is composed of the main paint and curing agent mixed. The main paint consists of the following weights of the following weights: epoxy resin 18‑25 weight, dilute agent 10‑15 weight, auxiliary 0.2‑3 weight portion, Graphene 0.1量2 weight, pigment 10‑15 weight, filler 35‑45 weight, tactile 0.5‑5 weight; the curing agent consists of the following weights of each raw material: amine resin 75‑‑‑85 weights, dilute agents 5‑15 weights, and additives 3‑8 weights.

Description

technical field [0001] The invention relates to the field of anti-corrosion coatings, in particular to a graphene-enhanced high-solid epoxy anti-corrosion coating and a preparation method thereof. Background technique [0002] According to relevant data, the economic loss caused by corrosion of metal materials in my country is relatively large every year, accounting for about 5% of the gross national product. From the perspective of the economics of anti-corrosion treatment, the use of anti-corrosion coatings is the most economical and effective method. With the continuous improvement of infrastructure design requirements, new requirements for coating performance requirements are constantly emerging, especially new requirements are put forward for the anti-corrosion protection life of coatings, the versatility of materials, and environmental friendliness. [0003] Traditional anti-corrosion coatings are generally classified by resin into epoxy, epoxy bitumen, chlorinated rub...
