Description
Technical field
The invention belongs to building material technical field, relate to a kind of method for preparing insulation blocks.
Background technology
Entered since 21 century, be accompanied by the high speed development of the realty industry of China, the demand of materials for wall grows with each passing day.Simultaneously, government also calls all industries " energy-conservation " always in rapid economic development, and " the residential building thermal technology and the heating and energy saving design standard " of formulation proposes energy-conservation 50% requirement to the heat preservation energy-saving of architectural exterior-protecting construction.Therefore, the development and application of thermal-insulating type materials for wall is very important.
Though original building-block has good mechanical performance and endurance quality, but its thermal property is relatively poor, be difficult to satisfy energy-conservation 50% requirement, and being filled building-block, thermal insulation mortar prepares insulation blocks, make it when keeping original excellent mechanical performances and endurance quality, can improve heat-insulating property significantly, satisfy the requirement of current construction work insulation.Also there is not report at present both at home and abroad about this respect technology.
Summary of the invention
The object of the present invention is to provide a kind of thermal insulation mortar that utilizes to fill the method that building-block prepares insulation blocks.
The insulation blocks that the present invention proposes is made up of building-block and thermal insulation mortar, and the hollow parts of building-block is filled with thermal insulation mortar.
The thermal insulation mortar that the present invention proposes, be made up of Portland cement, flyash, slag powders, light granules, polyvinyl acetate latex powder, cellulose ether, poly carboxylic acid series water reducer, dodecyl sodium sulfate, methyl silicon sodium alcoholate, water, the weight ratio of each component is:
