Reflective heat insulation waterproof anti-corrosion self-cleaning water-based paint and preparation method thereof

Abstract

The invention discloses reflective heat insulation waterproof anti-corrosion self-cleaning water-based paint and a preparation method thereof. The paint is characterized by comprising a high-performance reflective filler and an auxiliary agent having a self-cleaning function. The reflectivity of the paint is up to 92%, the emissivity is 0.91, and meanwhile the paint has waterproof and anti-corrosion performance, excellent weather resistance, excellent salt spray resistance and excellent chemical resistance. The temperature of a building during high temperature seasons of spring and summer canbe effectively reduced, the sunlight radiation heat is prevented from entering the building, the use time of air conditioners is shortened, and meanwhile the self-cleaning function can keep the outerwall of the building attractive for a long time. The paint has strong adhesion, good flexibility and a long service life and is especially suitable for the outer surfaces of all kinds of storage tanks, equipment and pipelines in oil refineries and chemical plants, the thermal insulation performance of the surface of the equipment can be effectively improved, the temperature of the equipment is prevented from being too high, a significant energy saving effect is achieved, and safety coefficients of running of the equipment are increased.

Description

technical field [0001] The invention relates to a reflective heat-insulating, waterproof, anti-corrosion and self-cleaning water-based paint, which is especially suitable for heat-insulating and waterproofing of concrete buildings, oil pipes, transport vehicles and pipelines. Background technique [0002] With the continuous development of society, human beings have become more and more dependent on energy, and the increasing energy consumption not only intensifies the global energy crisis, but also causes harm to the environment. Buildings have a strong ability to absorb light in the spectrum, especially light waves in the infrared band. The building heats up quickly under the condition of sunlight for a long time, and at the same time dissipates heat slowly, so it lasts for a long time after heating. In the southern regions where winter is warm and summer is hot, the indoor temperature of airtight buildings in spring and summer can reach above 60°C without taking cooling ...

AI Technical Summary

Problems solved by technology

At present, relatively mature foreign technologies include Japanese patent JP98-120946 heat insulation coating, although the effect is good, but it is an oily coating, which will have adverse effects on people and the environment during production and use.

However, the design and effect of domestic thermal insulation coatings are immature. For example, the thermal insulation coatings with application numbers 03147361.

At present, the actual use effect of domestic thermal insulation coatings is not satisfactory, and has not reached the stage of large-scale industrial production

[0004] In order to overcome the lack of performance of existing heat-insulating coatings, the present invention discloses a reflective heat-insulating, waterproof, and anti-corrosion water-based coating based on modified acrylic emulsion, combined with infrared reflective pigments and fillers, hollow reflective materials and additives.
