Heat reflection-emission lamina simulated-brick thermal insulation coating and preparation method thereof

Abstract

The invention discloses a heat-reflecting-emission lamina simulated-brick thermal insulation coating, which consists of the following raw materials in percentage by weight: 10 to 20 percent of fluorine-modified silicon-acrylic emulsion, 10 to 15 percent of hollow composite ceramic microspheres, 10 to 15 percent of infrared emission pigment and filler, 5 to 10 percent of infrared reflection nanomaterial, 0.5 to 2 percent of molecular bridge modifying material, 20 to 30 percent of other filler, 4 to 6 percent of aid and the balance of water. The simulated-brick thermal insulation coating has the functions of improving thermal reflection of sunlight and converting phonon-photon energy, converts the thermal energy of the sunlight into infrared in an atmospheric window and emits the infrared into the air, and simultaneously can reduce the thermal conductivity of the coating; and the coating greatly reduces the sunlight energy absorption of walls and has the energy saving effect.

Description

technical field [0001] The invention relates to a heat-insulating coating, in particular to a heat-reflecting-emissive thin-layer imitation brick heat insulation and a preparation method thereof. Background technique [0002] When people use paint to replace wall bricks and exterior wall decoration materials, it is difficult to give up their feelings for the cultural tradition of "Qin bricks and Han tiles". In order to meet people's requirements for decorative aesthetics, the "Sand Wall Paint" series of textured paints has been developed. ;Through the construction process, various patterns of "bricks and stones" are prepared, which also overcomes the safety hazards caused by the weight shortcomings and falling off of decorative wall tiles, but the problems of sun resistance and heat transmission resistance have not been solved. . Sunlight irradiates the surface of an object, causing reflection, refraction, absorption and transmission. If the solar heat ray is absorbed by th...

Chinese patent CN101565581A discloses a kind of emitting heat-insulating coating and its preparation method. The coating focuses on reflecting the solar radiation heat rays and blocking heat conduction to the inside, thereby reducing the temperature of the object to achieve a certain heat-insulating effect; but its heat-insulating The effect of the coating is not ideal, which limits the popularization and application of the coating to a certain extent.
