Abstract

The invention discloses a novel thermal insulation sintered block and a preparation method thereof. The novel thermal insulation sintered block comprises the following raw materials in parts by weight: 80-100 parts of coal cinder, 30-50 parts of red mud, 20-30 parts of perlite, 4-6 parts of nanosilica, 3-5 parts of a rosin resin and 5-8 parts of polyacrylamide. Comprehensive utilization of solid wastes is realized, the environmental pollution problem is reduced, and the prepared sintered block has excellent product performance and has the compressive strength of 18-22MPa, the water absorption rate of 10-12 percent, the density of 870-930kg / m<3> and the heat conductivity coefficient of 0.058-0.064W / (m.k). The sintered block disclosed by the invention has the advantages of high strength, low water absorption rate, low density, heat preservation, thermal insulation, good fireproof effect, wide raw material source, low cost, simple preparation process, low energy consumption and the like and has good market prospects.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and specifically relates to a heat-insulating and heat-preserving sintered block and a preparation method thereof. Background technique [0002] Protect land, save energy and resources, reduce pollutant emissions, protect and improve the environment, and implement sustainable development strategies. In social energy consumption, building energy consumption accounts for 35% to 45%, and the energy of buildings is mainly It is very necessary to vigorously develop new energy-saving building wall materials through the scattered and loss of the wall. Among them, the thermal insulation sintered block is a new type of energy-saving and environmentally friendly building wall material with excellent performance. Insulation sintered blocks not only have excellent thermal performance, but also have wide distribution of raw materials and low cost, so they have broad application prospects. It has ...
