Example Embodiment

[0031] The following examples are to further illustrate the present invention, but not to limit the scope of the present invention.

[0032] 1. Preparation of water-based anticorrosive and thermal insulation coating:

[0033] First add antifreeze, dispersant, and pH adjuster to the water, and stir with a disperser at 500 rpm for 20 minutes to obtain a dispersion. Add metal-modified zinc phosphate and physical fillers to the dispersion to obtain the first liquid. Stir at a high speed of 1000 rpm for 30 minutes, and add hollow microspheres and 1 / 2 amount of defoamer to obtain the second liquid. Finally, add the film-forming emulsion, the film-forming assistant, the anti-flash rust agent and the increaser to the second liquid. Thickener, stir at 500 rpm for 10 minutes at low speed, and finally add the remaining 1 / 2 amount of defoamer to obtain a water-based anti-corrosion and thermal insulation coating.

Abstract

The invention discloses an aqueous anticorrosive heat-insulation paint which is prepared from the following raw materials of, by weight, 5-40% of water, 0.5-2% of an antifreezing agent, 0.1-0.5% of a dispersant, 0.4-0.8% of an antifoaming agent, 0.5-7% of a thickening agent, 0.2-0.5% of a pH conditioning agent, 2.5-25% of metal modified zinc phosphate, 3-25% of cenosphere, 15-45% of a body filler, 20-50% of a film forming emulsion, 0.5-5% of a coalescing agent and 0.5-1.5% of a flash-rust inhibitor. The invention also discloses a preparation method of the aqueous anticorrosive heat-insulation paint. The aqueous anticorrosive heat-insulation paint provided by the invention is a single-coating multifunctional paint, has excellent anticorrosive performance and heat-insulation performance to guarantee various anticorrosion and heat-insulation indexes, is beneficial to popularization and utilization, and has a wide application prospect. The method provided by the invention has a simple product preparation and construction process, is easy to carry out, and is easy for industrial large-scale production.

Description

technical field [0001] The invention relates to the field of water-based anti-corrosion and heat-insulating coatings and the preparation thereof, in particular to a water-based anti-corrosion and heat-insulating coating containing metal-modified zinc phosphate and hollow microsphere fillers and a preparation method thereof. Background technique [0002] Metal materials occupy an important position in the field of materials due to their excellent mechanical properties and process properties, but metal corrosion has also caused huge losses to human society, such as storage and transportation equipment made of metal materials, petrochemical equipment, steel structure workshops, storage roofs and other facilities , due to long-term chemical or electrochemical action and corrosion damage, resulting in a large number of economic losses. Aiming at the problem of metal corrosion, a variety of technologies can be used to protect, slow down or prevent metal corrosion. The most effecti...
