Problems solved by technology

[0003] Water-based fluorocarbon paint can be divided into two-component water-based fluorocarbon coatings and one-component water-based fluorocarbon coatings according to the preparation process, film-forming mechanism and packaging methods. The paint has the advantages of weather resistance, corrosion resistance, and strong self-cleaning, but the use of two components has poor air permeability, and the production process and components are more complicated.

Embodiment 1

[0015] In the embodiment of the present invention, a two-component water-based fluorocarbon paint includes: A component and B component, wherein, the A component includes the following raw materials in mass fractions: water 6%, dispersant 1.1%, water-based 67% of fluorocarbon emulsion, 0.2% of wetting agent, 0.4% of defoamer, 2% of film-forming aid, 0.5% of thickener, 0.3% of defoamer and 0.2% of anti-corrosion and anti-algae agent. The B component is 22% curing agent.

[0016] The curing agent comprises 3-5% of rutile titanium dioxide mixed with 17-19% of resole phenolic resin.

[0017] The film-forming aid is preferably alcohol ester-12.

[0018] The thickener is an organic cellulose thickener, preferably hydroxypropylmethylcellulose.

[0019] The defoamer is preferably an organic polar compound defoamer.

[0020] A preparation method of two-component water-based fluorocarbon paint, adding water, dispersant, wetting agent and defoamer into a container and stirring for 10 ...

Embodiment 2

[0022] A two-component water-based fluorocarbon paint, including: A component and B component, wherein, the A component includes the following raw materials in mass fractions: 5% water, 2.4% dispersant, 69% water-based fluorocarbon emulsion, 0.2% wetting agent, 0.4% defoamer, 1.5% film-forming aid, 0.7% thickener, 0.3% defoamer and 0.2% anti-corrosion and anti-algae agent, the B component is 20% curing agent, Compared with Example 1, the content of water and curing agent is reduced, the efficiency and dispersion fineness of the dispersion process are improved, and the time for curing and film formation after construction is reduced.

[0023] The curing agent comprises 2.5-3.5% of rutile titanium dioxide mixed with 16.5-17.5% of resole phenolic resin.

Abstract

The invention discloses two-component waterborne fluorocarbon paint which comprises a component A and a component B. The component A is prepared from, by mass, 6% of water, 1.1% of a dispersing agent, 67% of waterborne fluorocarbon emulsion, 0.2% of a wetting agent, 0.4% of an antifoaming agent, 2% of a coalescing agent, 0.5% of a thickening agent, 0.3% of an antifoaming agent and 0.2% of an anticorrosion and anti-algae agent; the component B refers to a curing agent in mass fraction of 22%. On the basis of a solvent type waterborne fluorocarbon paint preparation method, the component A is prepared according to a post-emulsification method, and a preparation process is simple and feasible; by adding of a certain quantity of rutile titanium dioxide into the component B namely the curing agent, weather resistance and self-cleaning performance of the waterborne fluorocarbon paint can be further improved, and high breathability is realized.

Description

technical field [0001] The invention relates to the technology of decorative materials, in particular to a two-component water-based fluorocarbon paint and a preparation method thereof. Background technique [0002] Generally, the water-based fluorocarbon paint refers to an environmentally friendly one-component fluorocarbon emulsion coating with excellent performance of water-based fluorocarbon resin as the main component. It has excellent durability, easy construction, cleaning and long-term excellent gloss retention. Color retention properties. It is an ultra-durable decorative protective coating suitable for various building exterior walls, roofs and various building materials, which can greatly extend the service life of buildings. [0003] Water-based fluorocarbon paint can be divided into two-component water-based fluorocarbon coatings and one-component water-based fluorocarbon coatings according to the preparation process, film-forming mechanism and packaging method...
