Abstract
The invention discloses insulation masonry mortar for aerated concrete self-insulation building blocks in a severe cold area and a production method of the insulation masonry mortar. The problems of 'cold bridge', 'condensation', energy loss and cracking existing in the conventional common mortar masonry autoclaved aerated concrete building block wall are solved. The mortar consists of the following raw materials in parts by weight: 100 parts of cement, 10-50 parts of coal ash, 50-150 parts of cinder, 5-30 parts of expanded perlite, 5-50 parts of glass bead, 5-50 parts of high-performance insulation water retaining enhancer, 0.2-20 parts of soap-free emulsion powder and 0.1-10 parts of cellulose ether. The production method comprises the following steps of performing hydrophobic treatment on the surface of expanded perlite, preparing the insulation water retaining enhancer, mixing dry materials and adding water for blending. The method has the positive effect that the insulation masonry mortar with high insulation, high freezing resistance, high water retention, high compression resistance and high bonding strength, special for the aerated concrete self-insulation building blocks, in the severe cold area is obtained. The problems of cracking, hollowing, 'cold bridge' and 'condensation' generated by the common mortar are eliminated, and an aim of saving the energy by 65 percent in the aerated concrete building block self-insulation wall is achieved.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of severe cold area steam-pressing aero-concrete heat insulation building block special-purpose thermal insulation masonry mortar.
Background technology
Along with global energy worsening shortages, improve energy use efficiency and develop the important topic that renewable energy source is facing mankind.China's building energy consumption accounts for 27.6% of whole society's total energy consumption, and wherein northern area building energy consumption accounts for more than 40% of national building energy consumption, and building energy conservation is the major issue of Sustainable Construction Industry.The architectural exterior-protecting construction heat insulation system applied under construction at present mainly contains four kinds: the sandwich thermal insulated system of external thermal insulation system, exterior wall internal insulation system, exterior wall, wall self-insulation system.What the actual employing of current China construction work was many is mainly external wall heat insulation system, but there is a lot of problems, and e.g., work-ing life, short, especially selected heat insulating material for external mostly was polymeric foam plastics, and fire performance is poor, inflammable.
The structured material that wall self-insulation system mainly adopts autoclave aerated concrete building block to protect as architecture enclosing, is characterized in utilizing the heat-insulating property of materials for wall self to reach power conservation requirement.Autoclave aerated concrete building block, as a kind of novel wall material, itself has the advantages such as light weight, heat insulating, fire prevention, a large amount of profit are useless, low power consuming, good environmental protection.But, self heat insulation wall is built by laying bricks or stones as still used ordinary mortar in the past in northern frore area, then have that heat-insulating property is bad, poor water retention property, cohesive force are low and between autoclave aerated concrete building block performance difference larger, therefore between autoclave aerated concrete building block and ordinary mortar, the problems such as cracking, hollowing are easily produced, particularly there is serious " cold bridge ", " condensation " phenomenon in body of wall, building mortar layer causes serious power loss, and these problems hinder the further application of autoclave aerated concrete building block in northern frore area and popularization.
Summary of the invention
The object of this invention is to provide a kind of severe cold area gas concrete heat insulation building block heat-insulating masonry mortar, building by laying bricks or stones for self-thermal insulation wall building block, obtain the effect that mortar and walling characteristic match, overcome power loss and problem of Cracking that existing autoclave aerated concrete building block body of wall causes because of " cold bridge ", " condensation "
Another object of the present invention is to provide the production method of a kind of severe cold area steam-pressing aero-concrete heat insulation building block special-purpose thermal insulation masonry mortar, makes product of the present invention be able to suitability for industrialized production.
