Abstract

The invention discloses an anti-drag and abrasion-resistant paint for a natural gas line. Raw materials of the paint comprise two components A and B, wherein the component A comprises a phenolic aldehyde amine curing agent, a flatting agent, a defoaming agent, a dispersant, a thickening agent, white ceramic powder, red ferric oxide powder, mica ferric oxide, yellow iron oxide powder, light calcium carbonate and an environmentally-friendly mixed solvent; and the component B comprises epoxy resin, the flatting agent and the environmentally-friendly mixed solvent. The anti-drag and abrasion-resistant paint has the following advantages that: 1, compared with the conventional polyamide curing agent, the phenolic aldehyde amine curing agent has the advantages of more convenient construction in winter, better wettability for base materials, high coating crosslinking density, no pinhole and stronger solvent resistance and corrosion resistance; 2, the coating surface of the paint is smooth andspecular gloss can reach more than 70 and is improved by15 to 30 percent compared with that of the like products; and 3, the paint is added with an abrasion-resistant filler, such as white ceramic, hollow microsphere and the like, so the abrasion resistance of the coating is greatly improved.

Description

technical field [0001] The invention relates to an internal drag-reducing coating for natural gas pipelines, in particular to a drag-reducing and wear-resistant coating for natural gas pipelines. Background technique [0002] The transportation of natural gas is mainly completed by pipelines, which has the advantages of safety and low cost. Therefore, the research is suitable for drag-reducing coatings in natural gas transportation pipelines. It is very important to reduce the cost, protect the inner wall from corrosion by the medium, and prolong the service life of the steel pipe. [0003] The existing drag-reducing coatings for pipelines are made of polymer resin and its curing agent, plus certain additives and pigments and fillers. The disadvantages are that the surface friction coefficient of the coating is not low enough, and the wear resistance, The resistance to solvent immersion is not good. Contents of the invention [0004] The purpose of the present invention ...
