Building material and preparation method thereof

Abstract

The invention provides a building material and a preparation method thereof and relates to the field of construction. The building material comprises, by weight, 25 to 40 parts of yellow sand soil, 20 to 30 parts of expanded perlite, 25 to 30 parts of polyphenyl particles, 24 to 28 parts of polyurethane foam plastic, 20 to 30 parts of ash-calcium powder, 15 to 20 parts of quartz sand, 13 to 21 parts of bentonite, 15 to 25 parts of aluminum silicate, 11 to 15 parts of stearic acid, 5 to 9 parts of sodium formate, 8 to 14 parts of synthetic fibers, 5 to 7 parts of cement, 18 to 22 parts of electric furnace slag powder, 10 to 15 parts of a filler, 0.2 to 0.6 parts of a retarder, 0.3 to 0.5 parts of a water reducer and 4 to 6 parts of water. The preparation method comprises (1) raw material weighing, (2) polyurethane foamed plastic crushing, (3) stirring, and (4) molding, drying, cooling and storage. The building material solves the problem that the existing thermal insulation material has defects in buildings having high environmental protection, energy saving, sound insulation, tensile strength, compressive strength and heat preservation performance requirements.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a construction material and a preparation method thereof. Background technique [0002] Industrial waste materials are the main component of urban waste, accounting for about 15%-20% of the total urban waste. In 2008 alone, my country produced 3 billion tons of construction and industrial waste, and the data from 2010 to 2015 must be far greater than this. At present, industrial waste is mainly treated by traditional open-air stacking and deep-digging landfill. Although this method has a large processing capacity, is convenient and simple, and has low processing costs, it actually occupies a large amount of land resources and causes irreversible environmental pollution. [0003] With the implementation and development of building energy conservation, thermal insulation materials and products have been paid more and more attention by people. However, the currently used ma...
