Abstract

The invention relates to the field of heat-insulating materials and provides a composite material heat-insulting board and a preparation method thereof. Raw materials comprise 425 ordinary Portland cement, polyphenyl particles, polyvinyl acetate emulsion, an organic silicon waterproof agent, cellulose, a physical foaming agent and water. The preparation method comprises the following steps: in the preparation process, preparing foam from the foaming agent by a foaming method; mixing the foam and other raw materials; adding water and stirring uniformly; adding glass fiber gridding cloth on the heat-insulating board material; and after rolling and forming the board, irradiating the heat-insulating board for 5 to 7 minutes by using microwave with the frequency of 3 GHz, so that the prepared composite material heat-insulting board has excellent heat-conducting coefficient and low dry density.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a composite material thermal insulation board and a preparation method thereof. Background technique [0002] China has a large market for building energy-saving materials, especially building insulation materials. The energy loss of Chinese housing is roughly as follows: walls account for about 50%; roofs account for about 10%; doors and windows account for about 25%; basements and grounds account for about 15%. In order to achieve a 50% energy-saving rate in 2010, China's construction requires a comprehensive renovation of the building's exterior walls, and the market for wall insulation materials will increase significantly. [0003] Before 1980, the development of China's thermal insulation materials was very slow, but after more than 30 years of hard work in China's thermal insulation material industry, especially after nearly 20 years of rapid development, many ...
