Abstract

A two-component modified heavy-duty-anticorrosion epoxy mortar coating for super-thick membranization is composed of a component A and a component B, and the component A is composed of 8-13mass% of an epoxy resin, 2-7mass% of an epoxy active diluent, 5-19mass% of an epoxy resin modifier, 0.1-0.5mass% of a wetting dispersant BYK-110, 0.1-0.5mass% of an antifoaming agent BYK-A530, 4-5mass% of a multifunctional thixotropic agent, 5-10mass% of an alkaline water absorbing agent, 10-20mass% of a wear-resistant filler, 5-15mass% of an antirust pigment filler, and 10-25mass% of a pigment filler; and the component B is a phenolic aldehyde amine curing agent. The adoption of the optimized combination of the liquid epoxy resin, the epoxy active diluent and the epoxy resin modifier in the invention realizes the compactness, strong adhesion, excellent chemical resistance and strong anticorrosion property of a coat; and the production technology of the coating is simple, so the coating can be used for the super-thick membranization construction.

Description

technical field [0001] The invention relates to a heavy-duty anti-corrosion coating and a preparation method thereof, in particular to a super-thick film construction two-component modified epoxy mortar heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] Heavy-duty anti-corrosion coatings refer to a type of anti-corrosion coatings that can be applied in relatively harsh corrosive environments and have a longer protection period than conventional anti-corrosion coatings. It is mainly used in emerging marine engineering, modern transportation, energy industry, large industrial enterprises and other fields, and the design service life of heavy-duty anti-corrosion coatings required for concrete structures of bridges and wharves and marine steel structures is generally more than 15 years. The thickness of the coating is above 800 microns, which also requires the coating to have ultra-thick film construction. [0003] The main differe...
