Quick-drying anticorrosive dipping prime paint with low viscosity as well as preparation and application method thereof

Abstract

The invention discloses a quick-drying anticorrosive dipping prime paint with low viscosity as well as preparation and application methods of the prime paint and belongs to the technical field of dipping paints. The preparation method comprises the following steps of: mixing alkyd resin, dimethylbenzene, methylbenzene, acetic ether, thixotropic agent, pigments and padding and anticorrosive pigments; grinding in a grinder; dispersing the thixotropic agent and the round slurry again; adding chlorinated rubber, an anti-skinning agent, a drying agent and an anti-sag agent and uniformly stirring to obtain the dipping prime paint. The dipping prime paint is mixed with diluent to form dipping paint, and a workpiece is dipped by the dipping paint, the prime paint has low requirement on drying and can be dried at a low temperature or constant temperature. The prime paint is of a single-component type, has low viscosity and high anti-sag performance and is convenient in construction; dipping construction is directly carried out after the prime paint is diluted; the prime paint is not affected by seasons; a dried coating film is flat and compact, and a paint film is plump.

Description

technical field [0001] The invention belongs to the technical field of dipping paints, and in particular relates to a low-viscosity quick-drying anti-corrosion dipping primer and methods for preparing and using the same. Background technique [0002] Low-viscosity quick-drying anti-corrosion impregnating paint is an indispensable material for steel structures with complex structures, containers, ships and other industrial fields. It has simple construction characteristics and excellent gloss and color retention properties. It is suitable for high weather resistance High corrosion-resistant primer and topcoat. However, the low-viscosity quick-drying anti-corrosion impregnating paint currently on the market generally has a long drying time, poor anti-sag performance and anti-skinning performance. The construction is seriously affected by the seasons, and the actual application efficiency is low. Contents of the invention [0003] The purpose of the present invention is to p...
