Heavy anti-corrosion paint made of epoxy resin and basalt scales

Abstract

The invention discloses a heavy anti-corrosion paint made of epoxy resin and basalt scales. The paint comprises a component A and a component B, and is characterized in that: the component A comprises the following components in parts by weight: 20 to 40 parts of epoxy resin, 25 to 38 parts of dibutyl phthalate, 15 to 35 parts of dispersant, 20 to 40 parts of antifoaming agent, 20 to 39 parts of levelling agent, 10 to 25 parts of pigment zinc phosphate, and 12 to 78 parts of basalt scales; and the component B comprises the following components in parts by weight: 20 to 40 parts of polyamide and 25 to 40 parts of solvent. Basalt scales are adopted as the filling material, because of the labyrinth effect of the basalt scales, penetration of corrosive mediums is effectively prevented, the penetration rate is reduced by 8 to 9 times, and the paint has the advantages of high adhesive force, corrosion resistance, good penetration resistant property, low coating contracting rate, small thermo-expanding coefficient, low curing residual stress, wear resistance, simpleness for construction, and easy repairing.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to a heavy-duty anti-corrosion epoxy basalt scale anti-corrosion coating. Background technique [0002] Anti-corrosion coatings are widely used in petrochemical, metallurgy, chemical fiber, transportation, electric power, construction and other fields, especially in various marine engineering equipment, naval ships, oil platforms, steel structures of ports and wharfs, etc. [0003] The existing heavy-duty anti-corrosion coatings have poor medium permeability and wear resistance, short service life, and generally need to use glass fiber reinforced plastics or rubber linings when used. The construction conditions are relatively complicated, the efficiency is low, and maintenance is difficult. [0004] Generally contain volatile solvents, these volatile solvents will damage the health of the human body. In the case of good ventilation, the accumulation of this volatile solvent is less, whi...
