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

An environmentally friendly water-based primer, the weight percentages of its components are: component 1: 50-60% of silicate solution; 20-30% of metal oxide; 15-20% of acrylic emulsion; and 1-10% of auxiliary agent. Component 2: 70-80% zinc powder; 20-30% active magnet powder. Its advantages are: using water as solvent, non-toxic, non-polluting, and zero VOC emissions; after 30 minutes of surface drying, it can be washed with water; the coating surface can be matched with various anti-corrosion coatings, which can meet the needs of various long-term heavy-duty anti-corrosion projects ; Excellent resistance to organic solvents, and the coating film has excellent electrochemical anti-corrosion performance; can be continuously used at high temperature up to 650 ° C, can be welded, cut, and cut well; low resistivity can be anti-static, anti-radiation, UV-resistant, Salt spray resistance and long-term anti-corrosion effect; the flexibility of this product is better than that of general inorganic zinc-rich coatings.

Description

technical field [0001] The invention relates to the technical field of paint making, in particular to an environment-friendly and 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 they are in the environment of alternating dry and wet, sunlight exposure, high-speed water flow, salt spray, water medium, and microbial adhesion for a long time, and different degrees of corrosion generally occur. The time depends on the degree of anti-corrosion treatment to prolong its service life. General anti-corrosion coatings, such as: chlorinated rubber, iron red epoxy, epoxy and other coatings only have shielding effect. 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 generat...
