Description

A kind of cellular insulant
Technical field
The invention belongs to building material technical field, be applicable to the energy-saving heat preserving engineering of covil construction body of wall newly-built, that extend, transform and the cellular insulant of the energy-saving heat preserving improvement project of existing building body of wall.
Background technology
Lagging material is as a kind of large widely used material of construction, there is thermal and insulating performance, in modern construction engineering, bringing into play huge effect, yet conventional lagging material has combustibility, for construction, application have brought huge potential safety hazard, have a strong impact on people's the security of the lives and property.Therefore exploitation has insulation, heat-proof quality, and it is significant to have the lagging material of uninflammability energy.
At present, existing lagging material, can be divided into the large class of organic and inorganic insulation two.Organic and inorganic heat preservation is in performance and use and there are differences, aspect resource and environmental protection and fire safety aspect of performance, inorganic heat insulation material is better than organic insulation material, by scientific research, develop can recycle solid waste resource inorganic heat insulation material, the exploitation of these materials and technology and application, can promote the scientific development of building thermal-insulation energy-saving cause aspect energy-conserving and environment-protective and Sustainable development.
Summary of the invention
The object of the present invention is to provide a kind of starting material to be easy to obtain, have the features such as light thermal-insulation, the fire prevention of A level, low water absorption, high bonding force, low-carbon environment-friendly, energy-conserving profit waste, good endurance, the cellular insulant can manufacture.
A kind of cellular insulant that the present invention proposes, formulated by following compositions in weight percentage:
Silicate cement 45-55
Flyash 35-45
Hardening accelerator 4.0-5.0
Exciting agent 2.0-3.0
Suds-stabilizing agent 1.0-2.0
