Problems solved by technology

[0006] The purpose of this invention is to solve the problem that the existing oil pipelines and storage tanks have higher and higher requirements for salt spray resistance. During the production and construction of oil-based paints, a large amount of solvents volatilize, which is harmful to the human body and the environment, and some have a long curing time. Winter 48 Due to the problem of incomplete drying within hours, a water-based salt spray resistant epoxy primer was designed

Abstract

The invention discloses waterborne salt spray-resistant epoxy primer. The primer is prepared from a component A and a component B, wherein the component A comprises 15 to 55 parts of an epoxy emulsion with low molecular weight, 20 to 55 parts of an epoxy emulsion with high molecular weight, 20 to 60 parts of water, 0 to 1 part of a leveling agent, 0 to 2 parts of a drier, and 0 to 5 parts of polyurethane; the component B comprises 25 to 70 parts of a curing agent, 10 to 50 parts of zinc powder, 0 to 1 part of graphene, 5 to 30 parts of water, 0 to 2 parts of a dispersant, 0 to 2 parts of organic bentonite, and 0 to 3 parts of an antifoaming agent. The primer has the following beneficial effects: 1, the salt spray resistance of the epoxy primer prepared by adopting a natural drying technology can reach 1500 hours; 2, the production mode of existing traditional paint is changed, the water is used as a diluent, the discharge of pollution sources is reduced and the safety of production and transportation is improved; 3, water resistance is increased by 20% while the salt spray resistance is increased.

Description

technical field [0001] The invention relates to the field of epoxy primers, in particular to a water-based salt spray resistant epoxy primer. Background technique [0002] Oil pipelines (also called pipelines, pipelines) are composed of oil pipes and their accessories, and are equipped with corresponding oil pump units according to the needs of the process flow, designed and installed as a complete pipeline system to complete oil unloading and transportation Task. [0003] The oil pipeline system, that is, the pipeline system used to transport oil and petroleum products, is mainly composed of oil pipelines, oil stations and other auxiliary related equipment. For transportation equipment, compared with railway and highway oil transportation, which are also land transportation methods, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. [0004] The pipes of oil pipelines are generally steel ...
