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, and the anti-corrosion effect is general
In addition, in cold regions, exposed metal pipes are prone to bursting accidents in winter, especially the thermal insulation filler contains more inorganic fillers, and there is no good way to avoid problems such as poor elongation of the coating.
[0004] In order to overcome the problem of poor elongation of the existing heat-insulating coating, the present invention discloses a pressure-resistant and waterproof water-resistant coating based on compounded acrylic resin and polyurea resin combined with various heat-insulating fillers and graphene nanosheets.

Description

technical field [0001] The invention relates to a pressure-resistant, waterproof and environment-friendly paint and a preparation method thereof, which are suitable for anti-corrosion, waterproof and thermal insulation of chemical storage tanks and civil buildings and explosion-proof of metal pipes in winter. Background technique [0002] In recent years, the demand and consumption of energy in various countries in the world have increased year by year, which is in contradiction with the shortage of energy. As one of the best countries in global economic development, my country's dependence on energy is also increasing. In my country's energy consumption sector, building and industrial energy consumption is the highest. Therefore, the development of new energy-saving materials is of great significance for building and industrial energy conservation. [0003] As an effective material for preventing storage tank and building temperature, thermal insulation coatings have attr...
