Problems solved by technology

However, during the transportation process, the steel structure coated with the existing steel structure paint will be subjected to different degrees of collision and damage because it has to go through hoisting, truck transportation, or shipping, sea transportation, etc. Most of the coated steel structures need to be repainted or recoated after arriving at the destination, which not only wastes a lot of manpower and material resources, increases the cost, but also affects the progress of construction

Abstract

The invention relates to the field of coating technology in chemical technology, in particular to high-performance impact-resistance steel structure paint, which comprises a component A and a component B, wherein the component A and the component B are used in combination according to the mass ratio of the component A to the component B of (3-5):1. In the invention, dimer acid addition modified toughened epoxy resin is added with potassium hexatitanate whisker with a tunnel-like structure and phenolic aldehyde modified amine is used as a curing agent, so the paint has high mechanical performance, chemical performance and high impact resistance; besides high anticorrosion performance, the 200-micrometer-thick coating on carbon steel plate can resist 200kg.cm impact; a coating process is safe and exerts fewer influences on the environment; and the damage rate of coated steel pipes in a transport process is greatly reduced, supplementary coating or recoating times are reduced, labor and materials are saved, cost is lowered and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coatings in chemical technology, in particular to the development of high-performance impact-resistant steel structure coatings. Background technique [0002] Steel structure coating is one of many coatings. It is suitable for corrosion protection of sewage, seawater, industrial water, oil, gas and other pipelines, as well as bridges, electric equipment, grids and various chemical equipment. It has a wide range of applications prospect. However, during the transportation process, the steel structure coated with the existing steel structure paint will be subjected to different degrees of collision and damage because it has to go through hoisting, truck transportation, or shipping, sea transportation, etc. Most of the coated steel structures need to be repainted or recoated after arriving at the destination, which not only wastes a lot of manpower and material resources, increases the cost, but also affect...
