The present invention provides a kind of production method of building partition thermal insulation strip plate, including：It is protected by above-mentioned building partition
The composition of raw materials of warm batten is stocked up, and slurry, extrusion forming, maintenance is made in raw material.
Raw material is mixed with water when slurry is made.In some preferable embodiments of the invention, when raw material is mixed,
Quick-drying sulphate aluminium cement, coarse fodder and fines are first stirred evenly into obtain the first mixture.The first mixture and micro mist are stirred again
With the second mixture.Afterwards by the second mixture and water mixing.
Through inventor the study found that after first mixing other material compositions other than micro mist, then mix micro mist, raw material it is easy
More preferably with property, the batten that sizing material forming obtains has many advantages, such as that profiled sheeting is longer, surface density smaller.
The molding of slurry is operated using extrusion forming.Inventor, which studies, to be found to squeeze using the cooperation of quick-drying sulphate aluminium cement
It is molding to be bonded, be conducive to improve the adhesion strength of cementitious material between the materials, while advantageously reducing the face of product
Density.It is bonded using quick-drying sulphate aluminium cement, adhesion strength is high；The time of initial set and final set is shorter, early strong high, energy
Starting board demoulding is avoided, bundling, transhipment, the technological operation of links such as conserves in factory and leads to the integrality in early damage batten,
Stablize convenient for maintenance, product performance index.
The speed that re-packs of sheeting machine all has an impact the advance resistance of raw material, extruding force, to particle after molding, plate density
With influence.In some preferable embodiments of the invention, sheeting machine is using the speed that re-packs faster, specifically preferably
Such as can be 5m/min, 5.1m/min, 5.2m/min, 5.3m/min, 5.4m/min, 5.5m/min, 5.6m/ for 5-6m/min
Min, 5.7m/min, 5.8m/min, 5.9m/min, 6.0m/min etc., it is therefore preferable to 5-5.5m/min, more preferably 5.46m/
min。
Using the above-mentioned faster speed that re-packs, compared with the slightly slow speed that re-packs of conventional 2-3m/min, obtained item
The surface density of plate is significantly reduced.
Maintenance operations make the abundant aquation of plank, performance stablize.Moisturizing is the important link in maintenance operations, if humidity mistake
Conference entirely extends the production cycle of maintenance, can also reduce the cohesive force of concrete to a certain extent, it is not easy to generate stable
Crystallization；If relative humidity is too small cannot to reach maintenance effect, easy to produce that moisture evaporation in concrete is too fast to cause dehydrating phenomena,
Also cup shake is easy tod produce.
In preferred embodiments of the present invention, maintenance humidity 90-100%, curing temperature is 17-23 DEG C.What is conserved is specific
Operation is：After sheet metal forming when 25-35min, sprinkling water mist maintenance；It is sprayed every 100-120min after sprinkling water mist maintenance
