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...
