Residence, commercial and industrial building structure exterior-wall heat insulation.However, this organic foam material is shown very containing fire-retardant
The fire resistance of difference.When exposed to flame, organic foam material meeting conflagration, and generate harmful vapors.These organic foams
Material has led to many fatal fire incidents as external-wall heat-insulation material.
The heat-insulating material that non-combustible insulation board is used as building includes foam glass, foamed ceramics, glass mat, rock
Cotton plate and foam concrete, etc..Foam glass and foamed ceramics are usually valuableness, because their production is related at high temperature
Reason.In addition, foam glass and foamed ceramics are difficult to install due to its brittleness.Equally, the production of glass mat and rock wool board
Also a large amount of energy is consumed, because they need high-temperature operation.In addition, glass mat and rock wool board can easily absorb water
And lose its thermal insulation property.When glass mat and rock wool board absorb water, they often fall off from wall, cause potentially to endanger
Danger.In addition, fibrous insulant installation method is complicated.Foam concrete can be produced with relatively low cost.However, foam
The mechanical performance of concrete, such as compression strength, it is excessively poor.In addition, the mechanical property of foam concrete sharply declines in humidity.
Another fire resistance can preferable insulation board be a kind of to be formed by organic foam particle and inorganic bond
Composite insulation boards, this thermal insulation material has the superior heat-insulating property of organic foam particle, simultaneously as inorganic bond
Use, inorganic bond wrapped up organic granular, this material enabled to reach effective fire resistance energy.
