Problems solved by technology

This kind of water-based inorganic zinc silicate coating has a low viscosity and is not suitable for automatic high-pressure airless spraying. It is easy to cause gun blockage during spraying and affect construction efficiency.
In addition, the particle size of the Zn powder used in it is about 45 μm, and the thickness of the sprayed coating is more than 100 μm, which cannot meet the requirements of the film thickness of the shop primer.

Abstract

The invention provides a water-based inorganic zinc shop primer, which comprises a base-material and a curing agent, wherein the base-material comprises zinc, a filling material, pigment, rare earth oxide, a heterocyclic organic compound, a surfactant, water, an anti-settling agent and an antifoaming agent; the curing agent comprises an inorganic high-molecular film forming substrate, anacrylic acid monomer, styrene, methyl acrylate, ethyl acrylate, a dispersant, water, an antifoaming agent and a surfactant. The shop primer is used for ship or large-scale steel structure construction, has excellent anticorrosion performance, and is suitable for high pressure airless spraying to satisfy the production requirements of shop primer streamline, and satisfy the requirements of welding, cutting and the like. and can be used as a priming paint for temporary protection in the process for constructing large-scale heavy steel structures in ship construction factory or large-scale steel structure factory, the protection duration is 3-12 months.

Description

technical field [0001] The invention relates to a shop primer and its preparation and application, in particular to a water-based inorganic zinc shop primer and its preparation and application. Background technique [0002] Shop primer, also known as steel pretreatment primer and maintenance primer, refers to the first primer sprayed on the steel plate after spraying to a certain level. Its main function is to protect the steel plate during production (including welding, cutting, etc.) , pyrotechnic correction, etc.) are less subject to atmospheric corrosion, and are widely used in the construction of ships and large steel structures. For example, in the shipbuilding industry, it is generally equipped with a large-scale pretreatment and spraying shop primer production workshop. The purchased steel plate is directly sent to the workshop, and the automatic assembly line is used for shot blasting and derusting to a certain level, and then an automatic high-pressure airless spra...
