Preparation method for high-strength, lightweight and self-insulation block

Abstract

The invention discloses a preparation method for a high-strength, lightweight and self-insulation block. The block comprises the following raw materials: Yellow river clay, Nishan argillaceous limestone, polyimide powder, nanometer nickel, tantalum carbide, vanadium carbide, tungsten carbide powder, glass microbeads, a mixed solution 1, an additive I with a mass accounting for 2 to 3 wt% of the mass of the mixed solution 1, and an additive 2 with a mass accounting for 0.015 to 0.025 wt% of the mass of the mixed solution 1, wherein the mixed solution 1 comprises acrylic acid, polyvinyl alcohol,modified wheat straw and water. The preparation method provided by the invention has the following beneficial effects: the raw materials comprise the Yellow river clay and the wheat straw, so wastesare turned into treasure, and resources are comprehensively utilized; a wall body constructed by using the block provided by the invention does not need to construct an exterior wall for heat insulation; the strength is significantly increased; the early strength is high; the factory cycle of the block is greatly shortened; and the heat-insulation block prepared by using the preparation method provided by the invention has the advantages of excellent thermoengineering properties, light weight, high strength and low product water-absorption rate.

Description

[0001] This case is a divisional application. The invention name of the original application is: a lightweight self-insulating block. The filing date of the original application is: 2016-11-14, and the application number of the original application is: 201610999162.X. technical field [0002] The invention relates to the technical field of materials, in particular to a preparation method of a high-strength light-weight self-insulating block. Background technique [0003] The advantage of self-insulating blocks for external walls is that it is accompanied by the theme construction. The overall construction of the project has high timeliness. New wall materials sintered with river and lake silt and composite blocks produced from fly ash, slag, coal gangue and other materials have been fully utilized in our country. Standard bricks are used for load-bearing walls and perforated bricks are used for frame structure infill walls. The existing problem is that the wall cannot meet ...
