Description
Technical field
The invention belongs to building material field, more particularly to a kind of wall thermal insulation board.
Background technology
Building energy conservation is the important step of China's energy conservation, various in style for external wall heat insulating material for external, is whether there is
Machine material, organic material, composite etc.；Make the equal of isothermal holding for beam, post, shear wall and non-heat-insulation masonry material wall
For sheet material or mortar class insulation material.
At present, architectural engineering has using hard-foam polyurethane plate built in external mold and the built-in molding polyphenyl plate cast-in-place concrete exterior wall of external mold
Outer heat preservation system enters cross girders, post and the construction of shear wall part external wall outer insulation, and sheet material must use alkaline-resisting grid cloth or steel wire net rack
Strengthen, processing technology is complicated, involves great expense.Sheet material must be fixed with bar connecting in concrete during construction, complicated construction technique, and
After 20~25 year service life, this system one be pollute, two be secondary to construct.
For above-mentioned situation, now constructed mostly using A grades of fire-retardant heat-insulation materials, but A levels fire prevention in the market
Warming plate compression strength is not high, quality is crisp, make inner formwork pour muscle concrete smash shake when easily crush.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of fire prevention, pressure-proof and snap-resistent intensity is high and thermal and insulating performance is good
Wall thermal insulation board.
In order to solve the above technical problems, the technical scheme is that：A kind of wall thermal insulation board, its innovative point is：
The wall thermal insulation board is made up of the raw material of following parts by weight：
20~40 parts of flyash；
10~12 parts of cinder；
5~15 parts of cement；
2~8 parts of quick lime；
8~16 parts of gypsum；
10~20 parts of CHARACTERISTICS OF TAILINGS SAND；
6~8 parts of slag；
2~8 parts of ferronickel ground-slag；
1~2 part of binding agent；
2~3 parts of fire retardant.
Further, the specific surface area of the ferronickel ground-slag is 460-480m2/kg.
The advantage of the invention is that：Wall thermal insulation board of the present invention, each reasonable raw material proportioning, increase considerably its toughness,
Viscosity and water-resistance, and the rapid hardening characteristic of gypsum and flyash light weight, insulation and gypsum is uninfluenced, so as to optimize
The performance of wall thermal insulation board, and renewable resource utilization rate is high, it is cheap.
