Abstract

The invention relates to a preparation method of an insulating baking-free brick. The preparation method comprises the following steps: (1) premixing: adding water into raw materials including gangue, steel slag, gasification slag and boiler slag according to a certain mass ratio and stirring until the materials are uniformly mixed; (2) aging; (3) moulding; (4) press-fitting; (5) steam curing; and premixing and adding CaO and Na2SO4 as excitant, and adding a binder into a heat-insulation layer. By the preparation method, strength of the insulating brick is greatly enhanced; and gangue and steel slag, etc. are changed from waste into valuable things so as to save resources and protect the environment. The preparation method of the invention is simple and feasible, and is easy to realize. Strength of the brick prepared by the method is 3 times higher than strength of a common brick. The brick of the invention has huge market potential and wide prospect.

Description

technical field [0001] The invention belongs to the field of building materials, and more specifically, the invention relates to a method for preparing heat-retaining unburned bricks. Background technique [0002] With the popularization and application of thermal insulation bricks, the poor cohesion and low strength of thermal insulation bricks have gradually become a common problem in the field of building materials, which further limits the promotion and use of thermal insulation bricks. The currently used insulation bricks are common, with high cost, poor adhesion, and strength defects. Therefore, it is a social development trend to develop an insulation brick with high strength, strong adhesion, and low cost. Contents of the invention [0003] The problem to be solved by the present invention is to provide a method for preparing heat-retaining non-burning bricks. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: ...
