3) foaming, demoulding: slurry injection is inserted with and 3 position of anchoring piece mounting hole, the identical core model of shape
Mold in foaming, then in 30~40 DEG C of environment conserve 6~10h after demould；
4) initial curing: in temperature it is 20~30 DEG C by the green body after demoulding, conserves 3 in the environment of relative humidity >=70%
~7d；
5) level-one is cut: the green body after initial curing is subjected to level-one cutting, i.e., grown by required cement insulation board 1,
Width is cut, and green body length and width size is identical as cement insulation board 1 after cutting, with a thickness of cement insulation board 1
Several times；
6) composite flame-proof polyurethane foam plastics protective layer: the green body after level-one is cut is put into cuboid closed mold
In, mold above and below is fitted closely with green body above and below respectively, and the front, rear, left and right four of mold are stayed between side and green body
There is the gap of required 2 thickness of flame retarded polyurethane-foam plastic protective layer；By isocyanates, polyether polyol or polyester polyols
Alcohol, foaming agent, catalyst, foam stabiliser, water, fire retardant etc. inject foaming in mold after being sufficiently mixed according to the ratio, so
It is demoulded after 6~12min of post curing；
7) second level is cut: the green body after composite flame-proof polyurethane foam plastics protective layer being carried out second level cutting, that is, is pressed
The thickness of required resisting breakage foamed cement composite insulation boards is cut, and obtains resisting breakage foamed cement composite insulation boards green body；
8) it late maintaining: is sent out to get to resisting breakage of the invention within green body natural curing 21~25 days after second level is cut
Soaked mud composite insulation boards.
According to JC/T 2200-2013 " cement base foam heat-insulating board " standard to resisting breakage foamed cement composite insulation boards into
Row performance test, test result is as follows: test result are as follows: density 185kg/m3, compression strength 0.46MPa, volume water absorption rate
