Abstract

The invention discloses a preparation method of a self-insulating wallboard, and belongs to the technical field of building materials. The preparation method comprises the following steps: sequentially weighing the fowling components in parts by weight: 100-120 parts of cement, 20-25 parts of sand, 25-30 parts of mixed granules, 12-18 parts of modified glass microspheres, 20-30 parts of modified copper sheets, 3-5 parts of a foaming agent, 3-5 parts of chitosan, 5-10 parts of sodium silicate and 20-40 parts of water, firstly mixing the cement with the sand, adding water, carrying out stirringand mixing to obtain a pretreated blank, then sequentially adding the mixed particles, the modified glass microspheres, the modified copper sheets, the foaming agent, the chitosan and the sodium silicate into the pretreated blank, carrying out stirring and mixing to obtain a blank, injecting the blank into a mould, carrying out pressing formation to obtain a wallboard blank, and curing the wallboard blank, so as to obtain the self-insulating wallboard. The self-insulating wallboard obtained by the preparation method provided by the invention has excellent heat-insulating performance.

Description

technical field [0001] The invention discloses a preparation method of a self-insulating wallboard, which belongs to the technical field of building materials. Background technique [0002] my country is currently in the peak period of urban construction. According to statistics, the total construction area in 2010 has exceeded 40 billion m 2 , Building energy consumption accounts for about 30% of the total energy consumption in society. The annual energy loss through the building envelope accounts for more than 50% of the total building energy consumption. Among them, the wall in the envelope occupies the largest area and consumes the most energy. Building energy conservation has been mandatory since 1997. Therefore, building wall insulation has become the key to building energy conservation. The development of thermal insulation wall materials with ultra-low thermal conductivity and the exploration of matching energy-saving structures have become the focus of research an...
