Efficient energy-saving heat-insulation brick and method for preparing same

Abstract

The invention provides an efficient energy-saving heat-insulation brick and a method for preparing the same. The efficient energy-saving heat-insulation brick is prepared from river channel sludge, coal gangue powder, palygorskite powder, brucite fibers, glass fibers, modified aluminum oxide, hydroxypropyl guar gum, glycol distearate, polycarboxylate water reducing agents, fire-resistant oxide, styrene, pore forming agents, composite additives and water. The efficient energy-saving heat-insulation brick and the method have the advantages that the efficient energy-saving heat-insulation brick prepared by the aid of the method is low in heat conductivity, excellent in heat-insulation performance and mechanical property and high in anti-erosion ability; the method is simple and is low in cost, the efficient energy-saving heat-insulation brick is mainly made from waste pollutants, and accordingly the efficient energy-saving heat-insulation brick and the method have certain energy conservation and environmental protection benefits.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-efficiency energy-saving thermal insulation brick and a preparation method thereof. Background technique [0002] With the rapid development of society, the problem of energy shortage in the world is increasing day by day, and energy saving has been widely concerned by the whole world. Buildings are large energy consumers. A large amount of energy is consumed in buildings all over the world. In my country, building energy consumption is also increasing. Therefore, how to improve the energy utilization efficiency of buildings on the basis of satisfying user comfort, To make better use of natural energy while reducing the impact on the outside world is a topic that needs serious research. [0003] The promotion of building energy conservation and the development of green buildings are widely supported by people, which also stimulates the development of...

[0004] Publication date March 26, 2008, Chinese patent application with publication number CN101148071 "Method for producing light-weight high-strength sintered bricks using urban sludge and wet-discharged fly ash", the patent document discloses a method of using nearly half the amount of urban Sludge and more than half of the fly ash plus a small amount of fluxing pore-forming agent are mixed to make sintered bricks. This method uses a large amount of fly ash to make bricks, and the reuse of fly ash has been widely used. For example, in the manufacture of fly ash cement, fly ash concrete blocks, etc., fly ash has become a resource that costs a certain amount of purchase costs in many places. In addition, the amount of sludge treated by this method is small. The brick method is not ideal in many cities that urgently need to solve a large amount of sludge

Publication date August 6, 2008, publication number CN101234886 Chinese patent application "one-step comprehensive utilization of waste sintered microporous ecological brick method", the patent document discloses the use of 20-60 parts of domestic waste or sludge, 10- 20 parts of construction waste, 10-20 parts of fly ash, 20-40 parts of excavation spoil or coal gangue. Although the amount of waste used in this method is relatively large, the composition of fresh domestic waste is complex, which will inevitably affect the quality of bricks. Quality, from the several materials used, it is not possible to obtain ecological bricks that meet national standards, such as light weight, high strength, sound insulation, heat insulation, and low radioactivity, and construction waste excavation spoils do not need to be made into bricks. It is also easy to find other filling uses

Publication date September 17, 2008, publication number CN101265077 Chinese patent application "Process of producing energy-saving sintered bricks with silt", the patent document discloses the use of silt with a weight ratio of 10-50% and siliceous clay with a weight ratio of 50-90%. Binder clay or bentonite, etc., the disadvantage is that the urban sludge that can be consumed is relatively limited, and more other effective resources are consumed in order to digest urban sludge
