Problems solved by technology

Thermal spraying of zinc and aluminum is sprayed on the metal substrate after melting and atomizing the wire rod, which has residual stress, high porosity, and poor shielding performance, so a sealing coating must be added, and the zinc mist generated during construction is harmful to the construction team. Personnel are at great risk
Both organic and inorganic zinc-rich coatings use high-fineness zinc powder as raw material, which has good shielding performance on metal substrates, but organic mostly uses epoxy resin as base material, which does not have conductivity, so its anodic protection performance is far inferior to that of thermal spray coatings. Zinc, aluminum and inorganic zinc-rich coatings

Abstract

The invention discloses an environmental-protective water-based priming paint, which comprises two formulations: one is 50-60% metasilicate liquid, 20-30% metal dioxide, 15-20% emulsion and 1-10% adjuvant; the other is 70-80% zinc powder and 20-30% white compound Si-Ti rust-proofing powder. The invention adopts water as solvent without polluting and VOC drainage, which can bear washing after drying for 30 min.

Description

Technical field [0001] The invention relates to the technical field of paint making, in particular to an environmentally friendly high-efficiency water-based primer. Background technique [0002] Most of the metal components are made of carbon steel, manganese steel, cast steel and other materials, and have been exposed to alternating wet and dry conditions, sunlight exposure, high-speed water flow, salt spray, and water media, microbial adhesion and other environments for a long time. Anti-corrosion treatment should be carried out according to the degree of time to extend its service life. General anti-corrosion coatings, such as chlorinated rubber, iron red epoxy, epoxy and other coatings, only have a shielding effect. Hot-sprayed zinc and aluminum are sprayed on the metal substrate after the wire is melted and atomized. There are residual stresses, high porosity, and poor shielding performance. Sealing coatings must be added, and the zinc mist generated dur...
