Problems solved by technology

High-solid coatings are formulated with liquid epoxy resin and low-viscosity curing agent. The paint film has high cross-linking density and good adhesion, but has the problems of high brittleness and poor impact resistance. It is frequently loaded and unloaded in the drilling water tank Easy to crack and peel off during alternating changes
According to reports, solvent-free pure epoxy anti-corrosion coatings have been tested on drilling water tanks, but there are defects such as too fast increase in viscosity during construction, short service life, and unsatisfactory construction performance.

Abstract

Belonging to the technical field of paint and making methods, the invention relates to a fast curable environment friendly epoxy paint for drilling water tanks and a making method thereof. The method includes: in a stainless steel charging basket, adding bisphenol A low viscosity type epoxy resin, bisphenol F type epoxy resin, bisphenol A and bisphenol F mixed type epoxy resin and a cashew oil modified monoglycidyl ether epoxy active diluent, mixing the materials, under stirring, adding an anionic compound containing fatty acid and rosin acid, a hydrophobic particle containing organosilicon polymer and a modified urea solution, controlling the temperature at 25+ / -2DEG C, performing high speed stirring, and under stirring, adding zinc chrome, aluminum triphosphate, superfine silica powder and talcum powder, conducting high speed stirring for 0.25h, then carrying out grinding for 0.5-1h by a sand mill so as to obtain an A solution in the paint; and in another stainless steel charging basket, adding a phenolic aldehyde amine curing agent, linear aliphatic amine and an adduct epoxy curing agent, conducting high-speed stirring to mix the materials evenly to obtain a B solution in the paint.

Description

technical field [0001] The invention relates to a fast-curable environment-friendly epoxy coating for drilling water tanks and a manufacturing method, belonging to the technical field of coatings and manufacturing methods. Background technique [0002] The anticorrosion of drilling water tanks of early offshore drilling platforms or drilling ships mostly adopts epoxy coal tar pitch paint, which has excellent salt water resistance and low surface treatment construction adaptability, but its scope of application is limited because it contains carcinogens. Asphalt substitutes, aromatic C9 resin and coumarone resin, have the advantages of both performance and price, but have a high softening point, and need to add plasticizers and solvents to make coatings, and there are still problems of solvent volatilization and environmental pollution during use. question. When the coating system containing solvent is applied in the cabin, the solvent volatilizes slowly, and it takes more t...
