Description
Technical field
The present invention relates to building thermal insulation material technical fields, more particularly to a kind of building heat preservation material of cast in situs foaming
Material and preparation method, application method.
Background technique
Building energy conservation mainly reduces heat loss to guarantee that room temperature is constant, to reduce by using heat preserving and insulating material
The energy for pyrogenicity or refrigeration.Since organic insulation material thermal coefficient is low, heat preservation and insulation is good, is answered extensively at present
For building energy conservation.But organic insulation material is there is various drawbacks, for example raw material are using petroleum resources, the feature of environmental protection is poor,
It is inflammable, weatherability is poor, easy to aging etc..Especially with promote and apply further deeply, the inflammable defect of organic insulation material by
Step exposure, the serious safety for threatening people.Inorganic heat preservation is wide at present due to excellent flame-retarding and low cost
General application.
Inorganic heat insulation material is to select to have low-density, porous, fibrous inorganic particle or powder for aglite, is led to
It crosses compound with cementitious material, external additive, by a certain percentage through keeping the temperature coating material made of certain technique, can directly apply
It smears in surface of wall, plate etc. can also be prefabricated into.It generally requires prefabricated, therefore the application in shaped piece is limited.Thus
The appearance of in-situ foamed concrete substantially advances the extensive use of inorganic heat insulation material.
Foam concrete plays an increasingly important role in building heat preservation field.Foam concrete soybean passes through existing at present
Field inflation, nitrogen, carbon dioxide gas or air are introduced into concrete mortar, through overmolding, reasonable maintenance, make to be formed containing big
Metering-orifice hole.Scene inflation process is many and diverse and not easy to control.Therefore there is concrete foamer, the rosin such as used earliest
Soap, and the efficient surfactant etc. of high-foaminess later.However, being needed constantly since high surfactant forms bubble
Stirring, and the bubble formed is uneven, is easy to collapse, and the bubble relative closure of especially high surface formation is independent, meeting
The aquation for influencing concrete combines, and seriously affects the intensity of foamed concrete.
