Background technique
China is world architecture big country, and the usage amount of construction material accounts for 30% or more of world demand amount, needs to expend big
The construction material of amount, building energy consumption account for the 40% of national total energy consumption, realize that energy-saving and emission-reduction, building are saved by reducing building energy consumption
Type society is extremely urgent.
Currently, reducing building energy consumption realizes that the major way of energy-saving and emission-reduction is to construct construction wall thermal insulation material, both at home and abroad
Common building thermal insulation material mainly has using styrofoam, polyurethane and phenolic foam heat insulation plate as the organic insulation material of representative,
It is the inorganic heat insulation material of representative with rock wool, foam glass and expanded perlite class etc..Existing organic insulation material in the market
Mainly there is the organics plate such as EPS sheet, XPS plate, however organic insulation material fire protecting performance is B2 or B1 grades, and A grades of marks are not achieved
Standard can burn in the case of fire, and can generate a large amount of harmful vapors, generate very big shadow to personal safety and environment
It rings, especially building the fire occurred again and again mostly in recent years is to be caught fire to cause by this kind of foamed material.Inorganic heat preservation material

Table 1
Table 2
It can be seen from Table 1 that in Examples 1 to 10 in insulation board obtained sodium abietate presence, increase heat preservation
Bubble in plate, reduces the density of insulation board, and apparent density is 145~176kg/m3, and then increase the safety of material
Energy and thermal insulation property, the presence of silica aerogel powder further assign the good thermal insulation property of insulation board, and 25 DEG C thermally conductive
Coefficient and 60 DEG C of thermal coefficient difference < 0.0020W/ (mK), the combustibility test specification embodiment of the present invention 1~10 in table 2
In insulation board obtained there is good security performance.
It can be seen from Table 1 that poly- hydroxy acid, flyash, higher ridge in insulation board obtained in the embodiment of the present invention 1~10
The presence of soil and hydrophobicity rubber powder can assign the good mechanical performance of insulation board and waterproof performance, and insulation board obtained is dry to be received
Lower shrinkage is 0.3%~0.5%, and lower volume water absorption rate is 4.2%~5.8%.
It can be seen from Table 1 that embodiment 8 is higher relative to 1 thermal coefficient of embodiment, it may be possible to because in embodiment 8
Graphite plate foam beads, phenol formaldehyde foam particle are identical with the average grain diameter of glass bead, do not carry out gradation, and then intergranular
Compactness is lower, and the heat insulation effect of material is poor, so embodiment 8 is higher relative to 1 thermal coefficient of embodiment.
By Tables 1 and 2 as can be seen that comparative example 1 is higher relative to 1 thermal coefficient of embodiment and security performance is poor,
It may be because the parts by weight of sodium abietate are very few in comparative example 1, and then the bubble in insulation board is very few, the compactness of insulation board
It is excessively high, so the heat insulation effect of insulation board is poor and security performance is poor.
By Tables 1 and 2 as can be seen that mechanical performance poor (tensile strength, compression of the comparative example 2 relative to embodiment 1
Intensity and flexural strength are lower), coefficient of softing is lower, drying shrinkage is higher and volume water absorption rate is higher, it may be possible to because
The parts by weight of sodium abietate are excessive in comparative example 2, and then the bubble in insulation board is excessive, and the compactness of insulation board is too low, so
The mechanical performance of insulation board compared with, poor coefficient of softing is lower, drying shrinkage is higher, volume water absorption rate is higher and security performance compared with
Difference.
By Tables 1 and 2 as can be seen that comparative example 3 is higher relative to 1 thermal coefficient of embodiment, 60 DEG C of thermal coefficients with
25 DEG C of thermal coefficient differences are greater than 0.0020W/ (mK), it may be possible to because of the weight of silica aerogel powder in comparative example 3
Amount part is less, and the heat insulation effect of insulation board is poor, so comparative example 3 is higher relative to 1 thermal coefficient of embodiment.
By Tables 1 and 2 as can be seen that comparative example 4 is higher relative to 1 volume water absorption rate of embodiment, and security performance compared with
Difference, it may be possible to which, because of silica aerogel powder too high levels in comparative example 4, comparative example 4 is relative to 1 volume of embodiment
Water absorption rate is higher, and security performance is poor.
