Abstract

The invention belongs to the field of functional polymer materials, and especially relates to a thermal-insulation damping coating used for buildings, and a preparation method thereof. According to the preparation method, cross-linked polymer microspheres with a porous structure and titanium silicate compound microspheres with radiation functions are added into a silicone acrylic emulsion polymer as additives so as to obtain the building interior and exterior wall coating with thermal insulation and damping functions. The material heat conduction coefficient is reduced effectively under the synergistic effect of the inorganic titanium silicate compound microspheres and the organic polymer microspheres, via effective utilization of thermal radiation functions and light scattering effect, under the effect of the large amount of nano-scale or micron-scale pores of the above two functional additives. In addition, the glass-transition temperature of the silicone acrylic emulsion polymer matrix is relatively low, and the silicone acrylic emulsion polymer matrix also possesses a certain degree of noise absorption damping performance. The preparation method is simple and convenient; cost is low; thermal insulation effect is excellent; damping performance is achieved; and requirements of buildings and home decoration are satisfied.

Description

technical field [0001] The invention belongs to the field of synthesizing functional polymer materials, and in particular relates to a thermal insulation and damping coating for buildings and a preparation method thereof. Background technique [0002] With the development of science and technology and social progress, energy conservation and emission reduction has increasingly become the focus of attention of all walks of life. Under the premise of satisfying the requirements of use, the construction field also increasingly strengthens the use of energy-saving materials. Such as hot summer and cold winter, how to reduce the influence of the external environment on the interior of the building and maintain the indoor temperature has always been a hot spot in the research of the building materials industry. Therefore, the use of functional materials can effectively improve the thermal insulation performance of buildings, thereby reducing the energy consumption of air conditio...
