Baking-free insulating brick and production method thereof

Abstract

The invention relates to a baking-free insulating brick and a production method thereof. The baking-free insulating brick provided by the invention comprises the following raw materials in parts by weight: 490-590 parts of fragment, 260-320 parts of portland cement, 20-60 parts of dried sludge, 4-5 parts of lime, 1.8-30 parts of expanded perlite, 2-5 parts of straw, 3-5 parts of nut shell, 2.1-1.9 parts of animal wool fiber and 107-130 parts of water. The baking-free insulating brick provided by the invention is prepared by the following production steps: firstly, dewatering and drying sludge; adding lime to the dry sludge to be uniformly mixed; piling; stirring; deodorizing and sterilizing; simultaneously grinding straw, nut shell and animal wool fiber into microparticles; sequentially adding all the raw materials to a stirrer to be uniformly mixed; and finally, carrying out extrusion molding and maintenance on the mixture to obtain a finished baking-free insulating brick. The baking-free insulating brick produced by the invention has good heat insulation property and compressive strength and strong freezing resistance and crack resistance, and the radiation quantity of the baking-free insulating brick is far lower than industrial specified standards.

Description

technical field [0001] The present invention relates to bricks or building blocks for buildings, in particular to insulating bricks or building blocks for buildings. Background technique [0002] At present, the commonly used thermal insulation measures for building walls are generally to apply a certain thickness of thermal insulation mortar or external thermal insulation boards on the ordinary masonry external walls, but this method is cumbersome to construct, with long construction periods and high costs, and the walls are prone to cracking and seepage. Leakage will seriously affect the insulation effect of the building. In response to this situation, bricks and blocks that can directly prevent cold and heat insulation have been developed. Early bricks and blocks with good thermal insulation effect were mostly made by high temperature sintering. The production of such sintered insulating bricks and blocks consumes a lot of energy and pollutes the environment...
