Novel water-based rust-free aerosol anti-corrosion primer and preparation method thereof

Abstract

The invention provides a novel water-based aerosol anticorrosive primer free of rust removal, and a preparation method thereof. The novel water-based aerosol anticorrosive primer free of rust removal comprises the following components by weight: 50.0-55.0 parts of a water-soluble resin, 25.0-35.0 parts of water, 3.0-8.0 parts of a cosolvent, 1.0-2.0 parts of a dispersing agent, 0.5 -1.0 parts of a wetting agent, 0.5-1.0 part of a defoaming agent, 12.0-31.0 parts of a functional filler, 0.2-0.5 part of a preservative, 0.1-0.5 part of a penetrating agent, 0.2-1.0 part of a thickening agent and 40.0-50.0 parts of a DME propellant. The water-soluble resin is a polymer water-soluble epoxy modified organic silicon resin containing compound organic acidic group; and solid content of the water-soluble resin is 48-52%. The water-based aerosol anticorrosive primer free of rust removal can thoroughly solve the problems of secondary rust, halfway rust removal and relatively poor corrosion resistance; and the water-based aerosol anticorrosive primer free of rust removal is used by packaging in a form of aerosol can and has relatively high storage stability and construction.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel water-based rust-free aerosol anti-corrosion primer and a preparation method thereof. Background technique [0002] The water-based rust-free and anti-corrosion primer can be applied on the steel surface with rust, eliminating the traditional sandblasting and shot blasting processes, greatly improving production efficiency and saving a lot of construction costs, and due to the extremely low VOC (volatile organic compounds, Volatile organic compounds) emissions, less environmental pollution, has been greatly developed and applied in recent years. [0003] The water-based rust-free and anti-corrosion primers currently on the market mainly use water-based polymer emulsions as film-formers, and are used alone or in combination by adding phosphating solution, phosphoric acid and tannic acid, but these products generally have poor storage stability. , and poor permeability to the rust ...

AI Technical Summary

Problems solved by technology

[0007] Another object of the present invention is to provide a preparation method of a novel water-based rust-free aerosol anti-corrosion primer, the construction equipment is simple and easy to obtain, and the process operation is simple, and the prepared novel water-based rust-free aerosol anti-corrosion primer It can further solve the problems of secondary rust, incomplete rust removal, and poor corrosion resistance. It can be packaged and used in the form of aerosol cans, and has high storage stability and construction
