Abstract

The invention discloses a preparation method for a lightweight heat-preserving fireproof sheet material by utilizing hollow glass microspheres. The method comprises the following steps: subjecting a hollow glass microspheres by-product to high-temperature glassification treatment by utilizing a vertical electric furnace at 800 to 1200 DEG C, and sieving out glassified particles with a particle size of more than 2 mm so as to obtain a glassification material of the hollow glass microsphere by-product; mixing 45% to 55% of the glassification material of the hollow glass microsphere by-product, 15% to 25% of cement, 3% to 5% of a waterproof agent, 1% to 2% of an early strength agent, 5% to 10% of cellulose fiber and 15% to 25% of water, and carrying out uniform stirring so as to prepare a slurry; laying a fiber gridding cloth in a mold, and pouring the prepared slurry into the mold; and carrying out demolding and then carrying out curing so as to prepare the lightweight heat-preserving fireproof sheet material provided by the invention. The lightweight heat-preserving fireproof sheet material provided by the invention has the advantages of high utilizability of the hollow glass microsphere by-product, low cost and simple process; and the prepared lightweight heat-preserving fireproof sheet material has the advantages of light volume weight, low thermal conductivity, high compressive strength, A-level fireproofing grade and good social benefits.

Description

technical field [0001] The invention belongs to the technical field of preparing building materials from industrial solid waste, and in particular relates to a method for preparing light-weight heat-preserving and fireproof boards by using by-products produced in the production of hollow glass microspheres. Background technique [0002] The total energy consumption of buildings in my country has been increasing year by year, and its proportion in the total energy consumption has risen from 10% in the late 1970s to 27% at present, gradually approaching 30%. According to the research of the Department of Science and Technology of the Ministry of Construction, with the acceleration of urbanization and the improvement of people's quality of life, the proportion of my country's building energy consumption will eventually rise to about 35%. With such a large proportion, the high energy consumption of buildings has become an important restrictive factor for my country's economic de...
