Description
Technical field
The invention belongs to building material field, be specifically related to a kind of phenolic fireproof heat insulating block and preparation method thereof.
Background technology
There is the most eurypalynous insulation material both at home and abroad.Classify by material, insulation material can be divided three classes: metal heat preservation material
Material, organic insulation material, inorganic heat insulation material.The source of goods of metal heat preservation material still this material is little, and expensive is made
Cost can be greatly improved, it is impossible to be widely applied for insulation material for building.Organic insulation material is easy to burning,
Easily producing poisonous gas during high temperature, ageing-resistant, fire resistance is poor, these shortcomings all limit organic insulation material widely
Use.
Inorganic heat insulation material composition the most aging, have will not thermal expansion, cold events, cracking resistance, peel etc. good from
Body characteristic.Compared with general insulation material, there is oneself special performance superiority, be irreplaceable performance in construction material
Feature, and cost is relatively low, can save lot of materials, cost of labor.But, heat conductivity is high (i.e. applied thickness is big), insulation effect
The poorest.Inorganic heat insulation material is when wall thermal insulating, by the fractional energy savings of existing country supervisor's industry relevant regulations, insulation material
Thickness must strengthen, the biggest because of its unit weight again, not only increases built-loading, also brings inconvenience to construction simultaneously.
At present, it is accordingly required in particular to there is the insulation material of combination property, reach to prevent fires and do not fire, there is lightweight, high-strength, heat conduction system
Low, durable, the high insulating effect of number and the external wall outer insulation material of easy construction, the building that not only can be used for less than 100 meters is high
Degree, more can be used for all kinds of building heights of more than 100 meters.
Summary of the invention
For solving the problem that the coefficient of heat conduction is big and water absorption rate is high that existing inorganic heat insulation material exists, the present invention proposes
