Description
Technical field
The invention discloses a kind of preparation methods of high-strength light heat-preserving brick, belong to insulating brick preparing technical field.
Background technology
Insulating brick, a kind of building material, using synthesis of polymer material, also useful cinder, slag are processed into.It is main to use
It is filled in the wall of building constructions, has many advantages, such as light-weight, easy for construction, warming, become the main wall material of modern architecture
Material.
Insulating brick in existing construction material uses styrofoam based on polystyrene more or with flyash, perlite
Etc. being mixed with into insulating brick.Styrofoam is only used for exterior-wall heat insulation, it is impossible to be used in builds main wall body by laying bricks or stones, and polystyrene is not
It is fire-retardant, therefore its use scope is restricted.
Heat preservation is technically all existed in the market using the thermal insulation material of styrofoam, compact substance styrofoam and thermal insulation mortar at present
The defects of itself can not overcome and part not fully up to expectations.Styrofoam is the organic material extracted from oil.By temperature
Sensitivity is influenced, molecule activity is very active.Heat resisting temperature only has 70 DEG C, when measuring 70 DEG C through experiment, change in size after 48 hours
Rate reaches 5%.Northeast Area of China winter outdoor temperature is -45 DEG C~20 DEG C, and southern area summer metope temperature reaches as high as
To 70 DEG C~75 DEG C.For polyphenyl plate material by the acute variation of outside air temperature, warpage, cracking are inevitable.It is and common at present
The heat-insulating property of insulating brick does not reach requirement, and standard is not achieved in intensity.
Existing interior wall heat-insulating sound-insulating thermal insulation material is mainly based on aerated bricks, also using shale brick, clay brick.Add
The shortcomings that gas brick is although light, but it is maximum is exactly frangible, and intensity is insufficient, and is easily in powdery.But consider the light of it
The saving of confrontation building cost is extended use in recent years or constantly, instead of shale brick and clay brick.Shale brick glues
Cob brick, intensity is higher, but from great, greatly increases the load-bearing of building, and wall collapses human body is made in a fire
Into secondary damage it is larger, so this kind of partition block is gradually substituted.
Therefore, invent a kind of high-strength light heat-preserving brick has positive effect to insulating brick preparing technical field.
