Problems solved by technology

[0004] At present, most of the coating systems for the protection of electrical equipment shells are solvent-based paints, and water-based paints only account for less than 5-10% of the market share. Most of the water-based products come from foreign technologies, such as Akzo-Nobel, Nippon, and DuPont. , Kansai and other well-known international companies mainly focus on water-based two-component products.

Abstract

The invention discloses single component air-drying water-based rust inhibiting primer with curtaining capacity and used for an electrical equipment housing. The primer comprises components in percentage by weight as follows: 30%-50% of water-based resin, 1%-5% of a wetting dispersant, 0.1%-1% of a pH regulator, 5%-15% of rust inhibiting pigment, 15%-30% of pigment packing, 1%-8% of a coalescing agent, 0.5%-1.5 % of a wetting levelling agent, 0.5%-2% of a flash rust remover, 0.1%-1.5% of an antifoaming agent, 0.5%-2% of a thickener, 0.1%-1% of a mould-proof sterilizing agent and 5%-20% of deionized water. The invention further discloses a preparation method of the water-based rust inhibiting primer. The water-based rust inhibiting primer has lower film forming temperature, any cross-linking agent and curing agent is not required to be added, the primer can be rapidly dried and cured at normal temperature or a low-temperature baking environment ranging from 50 DEG C to 80 DEG C, construction is simple and convenient, and the product performance is comparable with that of solvent based paint.

Description

technical field [0001] The invention relates to water-based coatings, in particular to a flow-coatable single-component self-drying water-based antirust primer for electrical equipment shells. The invention also relates to a preparation method of the water-based antirust primer. Background technique [0002] Electrical equipment, such as servo motors, CNC machine tools, industrial robots, terminal distribution boxes of substations and power distribution stations, distribution lines of urban communication systems, and box-type substations that are being popularized in recent years, most of them are made of metal. Shell protection, but because of the high cost of aluminum alloy, its use is limited, so in practical applications, the surface of the steel plate is often coated with paint for protection. [0003] Due to the complex structure of electrical equipment shells, multi-faceted and porous workpieces, complex parts and overall coating processes, numerous processes, and st...
