Steam-free self-insulating block and preparation method thereof

Abstract

The invention discloses a steam-free self-insulation building block and a preparation method thereof, and relates to the technical field of building parts in bulk or other shapes in a building component. The steam-free self-insulation building block is prepared from the following raw materials by weight: in each cubic meter, 0.8-1.5kg of an animal protein-containing foaming agent, 0.5-0.8kg of zinc stearate, 1.2-1.5kg of a water reducing agent, 160-180kg of water, 0.6-0.8kg of an early strength agent and 453-645kg of a main raw material, and the steam-free self-insulation building block is prepared through stirring the main raw material and the early strength agent after physical foaming. By physical foaming, the internal structure of the steam-free self-insulation building block is changed, the problems that traditional materials cannot take into account of both thermal insulation and strength can be solved, the steam-free self-insulation building block has high compression strength and low thermal conductivity, and can be individually built into a wall; and the preparation method has the advantages of simple process, and low production cost and energy consumption.

Description

technical field [0001] The invention relates to the technical field of block-like or other-shaped building components in building components. Background technique [0002] As the form of energy becomes increasingly severe, building energy conservation becomes increasingly important. According to the current policy requirements of my country's building insulation and energy conservation, the use of wall energy-saving technology is the focus of implementing building energy conservation. In the heat loss of the whole building, the heat loss of the heat transfer of the enclosure structure reaches 70%-80%, and the heat loss of the air penetration in the gaps of doors and windows accounts for 20%-30%. Therefore, strengthening the thermal insulation of the maintenance structure is an important part of building energy conservation. [0003] Most of the current exterior walls need to use exterior wall insulation systems to meet the requirements of building energy conservation. The...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a non-steaming self-insulating block and its preparation method. The non-steaming self-insulating block changes its internal structure through physical foaming, which solves the problem that traditional materials cannot take into account both heat preservation and strength. High compressive strength, low thermal conductivity, and can be built into a wall alone, which solves the integrity and weather resistance of the building insulation wall, so that the service life of the wall insulation system is truly the same as that of the building; steam-free self-insulation The preparation method of the block has simple process, low production cost and energy consumption
