Problems solved by technology

This construction process can ensure the surface treatment effect and overcome the difficulty of sandblasting and dust removal after welding. However, the pre-coated primer before the overall anti-corrosion is often completely cured, and the surface needs to be roughened before the topcoat can be applied.
At present, the roughening of the surface of the primer is mainly done manually, which has problems such as uneven treatment and easy to leave dead angles, and is time-consuming, laborious and inefficient, which seriously affects the quality and progress of anti-corrosion construction.

Abstract

The invention relates to a coating interface treating agent and a preparation method thereof. The preparation method comprises the following steps of: adding a titanate coupling agent NDZ-401 and LTH adhesive force promoting resin into a main solvent formed by butanone, n-butyl alcohol and cyclohexanone and adding BYK401 for sufficiently mixing. When the coating interface treating agent is sprayed onto the surface of a cured coating, the coating can be slightly swelled; after permeated into the surface of the slightly swelled coating, the coating interface treating agent interacts with the components of the cured coating so that an adhesive force between the coating interface treating agent and the newly coated coating on the upper layer is equal to the force of artificial hacking, and therefore, the artificial hacking technology with lower efficiency and difficulty in construction at present can be replaced.

Description

technical field [0001] The invention relates to a coating interface treatment agent and a manufacturing method, which can slightly swell the fully cured coating, and interact with the components of the cured coating by penetrating into the slightly swollen coating surface, so that it can be combined with the new coating on the upper layer. The adhesion between coating layers is equivalent to that of artificial napping, thus replacing the current low efficiency and difficult construction of artificial napping. Background technique [0002] The anti-corrosion construction of large-scale steel structures such as crude oil storage tanks and offshore platforms begins with surface treatment, primer coating, welding, and overall anti-corrosion construction at the end. This construction process can ensure the surface treatment effect and overcome the difficulty of sandblasting and dust removal after welding. However, the pre-coated primer before the overall anti-corrosion is often c...
