Sound-absorbing light-insulating heat-preserving material and preparation method thereof

Abstract

The invention provides a sound-absorbing light-insulating heat-preserving material and a preparation method thereof. The sound-absorbing light-insulating heat-preserving material comprises the following materials in percentage by volume: 10%-15% of resin, 55%-60% of clay or lime, 12-18% of cement, 12%-18% of gypsum and 12%-18% of fibers or rock wool. The method comprises the following steps of: firstly placing the resin, cement, clay or lime and gypsum into a container in proportion and stirring; after the resin, cement, the clay or lime and gypsum are uniformly stirred, slowly blowing the fibers or rock wool into the stirring container by utilizing an air blower, and stirring while blowing till the fibers or rock wool prepared in proportion is completely delivered into the stirring container; uniformly stirring the mixed material, naturally foaming and solidifying for 24 hours in a mold, then taking out of the mold, and drying for 5-7 days. The sound-absorbing light-insulating heat-preserving material provided by the invention is mainly used for the heat preservation and heat insulation of building houses and used for filling materials of bridges, highway isolation strips and the like and can meet the actual requirements for wind prevention, rain prevention, collision prevention, ventilation, light insulation, sound absorption, heat preservation, cold protection and the like of roads and bridges.

Description

technical field [0001] The invention relates to the field of research and development of new materials, in particular to a sound-absorbing, light-insulating, heat-insulating material and a preparation method thereof. Background technique [0002] The weather is cold in winter, and the insulation of the house is poor, so it is usually necessary to rely on heating to survive the severe winter; similarly, the temperature in summer is high, and the temperature inside the house quickly rises with the increase of the ambient temperature outside, making the room hot in summer, warm in winter and cool in summer It has always been the ideal residence that people yearn for; with the improvement of people's living standards, there are more and more cars, and the cars whizzing by on the road bring convenience to people's lives, but also make people stay in the noise for a long time, and at night There are also lights that affect people's sleep quality, especially people who live near th...
