Abstract

The invention relates to a bi-component long-acting-corrosion-resistant epoxy coal tar pitch anticorrosive coating material. The coating material is prepared from a component A and a component B which are in the weight ratio of 6: 1; the component A is prepared from the following ingredients: dimeric acid modified epoxy resin, coal tar pitch, anticorrosive pigments/fillers, a variety of adjuvants and a special mixed diluent for anticorrosive coating materials; the component B is an epoxy curing agent containing an imide structure; and the epoxy coal tar pitch anticorrosive coating material is obtained through mixing the component A and the component B. The bi-component long-acting-corrosion-resistant epoxy coal tar pitch anticorrosive coating material disclosed by the invention has excellent seawater resistance, durability, adhesive power, toughness, resistance to chemical corrosion and aging resistance; the film forming speed for coatings is high, and brush-coating is carried out at low temperature; and the bi-component long-acting-corrosion-resistant epoxy coal tar pitch anticorrosive coating material is applied to general buried pipelines, steel storage tanks and the like.

Description

technical field [0001] The invention relates to the technical field of coating chemicals, in particular to a two-component long-acting corrosion-resistant epoxy coal tar pitch anticorrosion coating. Background technique [0002] Epoxy coal tar pitch coating is a kind of anti-corrosion coating that appeared in the 1960s. It combines the acid resistance, alkali resistance, water resistance of coal tar pitch and the adhesion, mechanical strength and solvent resistance of epoxy resin. It is an excellent anti-corrosion coating. Variety of corrosion coatings, widely used in water conservancy, petrochemical, shipbuilding and transportation industries. A two-component long-acting corrosion-resistant epoxy coal tar pitch anti-corrosion coating of the present invention has excellent seawater resistance, durability, adhesion, toughness, chemical corrosion resistance and anti-aging performance; the film-forming speed of the coating is fast and low temperature Brush. Suitable for oil a...
