Abstract

An aqueous anti-rusting paint and a preparation method therefor. The paint is characterized in that: the raw materials in a formula in parts by mass are as follow: 600-700 parts of an acrylate modified alkyd resin emulsion, 100-120 parts of deionized water, 90-110 parts of pigments and fillers, 5-10 parts of a rheological agent, 5-10 parts of a dispersant, 1-5 parts of a defoamer, 1-3 parts of a bactericide, 70-90 parts of film forming auxiliaries, 15-25 parts of a co-solvent, 3-8 parts of a flash-rust agent, 5-10 parts of a multi-functional agent and 4-10 parts of a thickener solution. The process steps comprises: dispersing, milling, paint mixing, thickening, filtering and packaging. According to the present invention, water is used as a dispersion medium, multiple anti-rusting mechanism of physical, chemical and the like are used to prepare and produce the anti-rusting industrial paint. The paint combines an undercoat and a finishing coat and is constructed at one-time, so that the mode that the undercoat and the finishing coat of the conventional paint are constructed separately is broken. The paint is unequalled in environmental protection performance, good in salt-spray resistance and weather resistance and strong in anti-rusting function, and is an excellent product of a new generation that can replace the traditional anti-rusting paint. The paint has water solubility and non-flammable property, and is safe in use, and the paint is good in water resistance and good in thermal stability, and has a good anti-rusting function even in a high-temperature state.

Description

technical field [0001] The invention belongs to the technical field of paint manufacture, and in particular relates to a water-based antirust paint with an acrylic modified alkyd resin emulsion as a base material and a preparation method thereof. Background technique [0002] The antirust paint currently used is roughly two types: oily and water-based. Oil-based antirust paint makes it difficult to remove the greasy surface of the material, so it is rarely used. Oil-based antirust paint is easy to use and low in price, but because it contains toxic substances such as nitrite and chromate, it is harmful to operators. Rust requirements. [0003] The water-based metal anti-rust paint is made of metal strong chelating agent phytate as the main component, and is compounded with several other water-based additives. Phytate is a natural non-toxic organic chemical product extracted from food crops. When it is used as an antirust agent for magnetic materials, it can quickly chelat...
