Description
Technical field
The present invention relates to warming plate technical field, and in particular to a kind of cement insulation board and preparation method thereof.
Background technology
China is as building big country, and building energy consumption accounts for 27% or so of national total energy consumption, but building energy conservation level is far low
In World Developed Countries, unit building energy consumption is 3-5 times of the close developed country of weather.Development of Novel building energy conservation environment-friendly materials
For improving resource utilization, improving environment, energy-saving and emission-reduction, have important practical significance.Heat insulation plate for building is mainly used in
The positions such as building masonry wall, roof, window, floor, play a part of heat-insulation and heat-preservation, are the important indicators of building energy conservation environmental protection.
Existing cement insulation board cryoprotective effects are not good.
The content of the invention
It is an object of the invention to provide a kind of cement insulation board and preparation method thereof, anti-freezing property is stronger, uses the longevity
Life length, preparation method is simple, plays energy-saving heat preserving effect.
The invention provides following technical scheme：A kind of cement insulation board, includes the raw material of following part meter：Silicic acid
60 ~ 70 parts of salt cement, 40 ~ 50 parts of granular polystyrene, 33 ~ 36 parts of composite modified fiber grain, 29 ~ 31 parts of calcium sulfate crystal whiskers, foaming
110 ~ 120 parts of 10 ~ 11 parts of agent, 8 ~ 10 parts of binding agent, 8 ~ 10 parts of coupling agent, 5 ~ 7 parts of foam stabilizer and deionized water；
The composite modified fiber grain includes the raw material that following part is counted：14 ~ 16 parts of bamboo fibre, 12 ~ 13 parts of chopped strand, modification
8 ~ 9 parts of sawdust powder, 8 ~ 9 parts of expanded perlite, 4 ~ 5 parts of talcum powder, 4 ~ 5 parts of activated carbon and nano oxidized 16 ~ 17 parts of zinc solution.
Wherein, the granular polystyrene is that bulk density is 5~22kg/m3Primary granular polystyrene.
Wherein, the calcium sulfate crystal whiskers are the α type hemihydrate calcium sulfate crystal whiskers being prepared from by industry by-product gypsum, and length is
10~100 microns, the industry by-product gypsum is any of desulfurated plaster, ardealite and fluorgypsum.
Wherein, the foaming agent includes the raw material that following part is counted：10 ~ 12 parts of gelatine, 5 ~ 6 parts of Lauxite, dodecyl
1 ~ 2 part of 2 ~ 3 parts of benzene sulfonic acid sodium salt and triethanolamine.
Wherein, the foam stabilizer is empgen BB or calcium stearate, and the binding agent is waterglass, the idol
Connection agent is silane coupler.
Wherein, the preparation method of the bamboo fibre is：Bamboo is blocked and is cut into bamboo chip, takes bamboo chip to be put into 90 DEG C waters
10 ~ 20min of boiling, taking-up is crushed to filament, filament is put into continuation 30 ~ 40min of boiling in pressure cooker, by the filament after boiling
It is immersed in the solution containing biology enzyme and handles, bamboo fibre cleaning, bleaching, soft and shredding after then being decomposed by biology enzyme
Comb, obtain the bamboo fibre.
Wherein, the chopped strand be polypropylene fibre, polyethylene fibre, glass fibre, vinylon fibre, polyester fiber and
One or more in basalt fibre, the unit weight of the expanded perlite is 60 ~ 75kg/m3。
Wherein, the preparation method of the nano oxidized zinc solution is：Ammoniacal liquor is added drop-wise in zinc nitrate solution, makes solution body
It is that pH value is more than 9, then precipitation is obtained with funnel, sediment is then washed with deionized, until the pH value of system is 7, Xiang Chen
The salpeter solution that concentration is 65 ~ 75%, stirring are added in starch until system pH is 3.5~4.1, you can obtain nano oxidized
Zinc solution.
Wherein, the preparation method of the modified sawdust powder is：Starch and neopelex are weighed according to proportioning, plus
Enter into water, stir and heat with 90 ~ 100r/min rotating speed, heating-up temperature be 65 ~ 80 degrees Celsius, the heat time be 10 ~
20min, obtains pasty mixture, sawdust powder, plant ash, vegetable oil and aluminium powder is sequentially added thereto, with 200 ~ 250r/min
Rotating speed continue stir 10 ~ 15min, will obtained drying materials sieve after obtain the modified sawdust powder.
The present invention provides a kind of preparation method of cement insulation board, comprises the following steps：
（1）, prepare modified polyphenyl particle
Binding agent and 80% deionized water are weighed, granular polystyrene and coupling agent are added after mixing, with 200 ~ 300r/min's
