Problems solved by technology

[0003] The construction feature of coatings for metal inner cavities is that the façade is poured into the flow coating, but since the coating must be diluted to a certain extent before it can flow, and at the same time meet the anti-corrosion requirements, it is bound to require that the coating film must reach a certain thickness. The two contradict each other, and the actual operation Ordinary anti-corrosion coatings are not easy to flow evenly when they are thick, and can be flow-coated after diluting, but the film thickness is uneven, the film-forming property is poor, and the proper protection cannot be achieved. In order to ensure the safety of steel and metal products, we look forward to developing new anti-corrosion coatings. Heavy duty coating

Abstract

The invention discloses a high solid metal inner cavity anticorrosive paint and a production method thereof. The invention aims to provide a paint which can be widely applied to the inner wall of an iron metal inner cavity and ensure that a cured paint film formed by paint achieves favorable resistance and better mechanical performance and adhesive force and a production method thereof. The paint is formed by combining an A component and a B component by ratio of 100:30-35 in parts by weight, wherein the B component is modified aliphatic polyamine curing agent; and the A component comprises the following components in parts by weight: 50-60 solvent-free ethoxyline resin, 20-25 anticorrosive pigment, 20-25 titanium dioxide, 5-6 diluent, 0.5-1 dispersing agent, 0.2-0.4 flatting agent and 0.2-0.4 defoaming agent. The invention forms a thicker film by the ethoxyline resin with low molecular weight in flow viscosity and can achieve the function of protection. The paint is free from solvent and meets the anticorrosive requirement of the metal inner cavity by a technical route of the modified amine cured ethoxyline resin.

Description

technical field [0001] The invention relates to a coating, more specifically, to a high-solid metal inner cavity anti-corrosion coating and a production method thereof. Background technique [0002] The inner cavities of various metal products, such as the inner walls of automobiles, aircrafts, and mechanical facilities, are not only required to have good corrosion resistance to metal substrates such as paint and steel due to the harsh working environment, such as acid, alkali, hot water, oil, etc. Adhesion, and requires excellent water resistance, hot water resistance and salt spray resistance. Its comprehensive performance requirements are very high, especially the technical requirements for inner cavity anti-corrosion coatings are strict, not only must pass water resistance, resistance to various machine oils, but also require salt spray resistance and heat resistance of 150°C / 48h. [0003] The construction feature of coatings for metal inner cavities is that the façade ...
