Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of inorganic heat-insulation board and preparation method thereof.
Background technology
At present, lagging material conventional both at home and abroad has polystyrene foamed plastics (EPS, XPS), hard foamed poly urethane (PU) etc., advantage is lightweight, good heat preservation performance, but these organic foam materials are easily aging, can not the life-span same with buildings, within the buildings usage period, need repeatedly to change thermal insulation layer, consume a large amount of human and material resources, financial resources.More seriously its fire safety performance is poor, repeatedly there is the fire failure that organic insulation material is caused by igniting in various places, as Zhong Huan mansion, Nanjing, Gemini mansion, Harbin, the Olympic Sports Center, Jinan, cultural center of CCTV, teacher apartment, Jiangzhou, Shanghai, Shenyang feudal dynasty ten thousand prosperous mansion, Beijing University Gymnasium (Olympic Games table tennis training hall), the new shop of China Science and Technology Hall etc., during fire, smog is large, toxicity is large, cause huge financial loss and loss of life and personal injury, cause the great attention of relevant departments, the fire resistance of lagging material is had higher requirement, inorganic heat insulation material is good because having fire resistance, ageing-resistant, deformation coefficient is little and close with body of wall, with body of wall cohesive strength advantages of higher, cause the extensive concern of people.Existing cement foaming insulation board also also exists the shortcomings such as intensity is low, and thermal conductivity is high, inflammable.
Summary of the invention
The problem to be solved in the present invention is to provide the inorganic heat-insulation board and preparation method thereof of a kind of high strength, low thermal conductivity.
For achieving the above object, of the present invention adopted technical scheme is:
A kind of inorganic heat-insulation board, is characterized in that being made up of the component of following weight part: cement 15-20 part, pottery sand 30-40 part, drift pearl 10-20 part, water glass 10-20 part, gypsum 4-8 part, nano-calcium carbonate 15-30 part, Citric Acid, usp, Anhydrous Powder 6-8 part, triton x-100 0.2-0.5 part, water 8-15 part.
Preferably, be made up of the component of following weight part: cement 16-18 part, pottery sand 33-37 part, drift pearl 14-18 part, water glass 12-16 part, gypsum 5-7 part, nano-calcium carbonate 18-25 part, Citric Acid, usp, Anhydrous Powder 6-8 part, triton x-100 0.3-0.5 part, water 8-12 part.
Preferred further, be made up of the component of following weight part: cement 17 parts, pottery 36 parts, sand, drift 16 parts, pearl, water glass 15 parts, 6 parts, gypsum, nano-calcium carbonate 20 parts, Citric Acid, usp, Anhydrous Powder 7 parts, triton x-100 0.3 part, 12 parts, water.
Further, rubbing of described water glass counts between 2-3.Described cement selection grade is the silicate cement of 42.5 or 42.5R.
A preparation method for above-mentioned inorganic heat-insulation board, comprises the following steps: (1) to tile one deck alkali resistant glass fibre open weave cloth at mold bottom, and at mould surrounding brushing releasing agent, for subsequent use; (2) cement, pottery sand, drift pearl, gypsum, nano-calcium carbonate are joined in stirrer and stir 3-5 minute, then Citric Acid, usp, Anhydrous Powder, water glass and water are mixed to form mixed solution by (3); (4) mixed solution in step (3) is joined in stirrer and continue to stir 3-5 minute, obtain the slurry stirred; (5) slurry stirred is paved in mould, vibration compacting, be pressed into one deck alkali resistant glass fibre open weave cloth at upper surface, with covered rearing with plastic film maintenance 5-7 days, obtain above-mentioned inorganic heat-insulation board.Preferably, churning time is 3 minutes.
The advantage that the present invention has and positively effect are:
(1) composition of the present invention is simple, scientific and reasonable, warming plate good heat insulating, and bonding strength is high, and thermal resistance performance is good, can significantly improve Construction Quality;
(2) application of water glass can not only improve intensity and the degree of compactness of warming plate, because its viscosity greatly can also as suds-stabilizing agent, use composite with nano-calcium carbonate, its molecule can produce larger internal friction when the aqueous solution flows, and causes soltion viscosity to raise, and then adds liquid film surface strength, the liquid that liquid film is closed on not easily is discharged, the speed that thickness of liquid film diminishes is comparatively slow, has delayed the time of liquid-sheet disintegration, has added the stability of foam;
(3) float pearl and there is its special hollow ball structure, not only can improve the fire resistant heat preserving performance of material, also because ball effect can improve the aid pumpability of slurry, reduce difficulty of construction;
(4) triton x-100 and the composite use of Citric Acid, usp, Anhydrous Powder, can significantly improve the water resistance of material;
(5) nano-calcium carbonate both can be used as whipping agent in the present invention and makes material have excellent heat-insulating property, again can space between packing material, made structure become more closely knit thus improved the ultimate compression strength of warming plate.
