1 polystyrene chromatic steel sandwich plate preparation technology parameter of table
2 fireproof heat insulating gluing agent prescription of table
It is sufficiently stirred and is uniformly dispersed after above-mentioned substance is weighed by weight, obtain fireproof heat insulating adhesive.
3 color steel sandwich plate adhesive layer of table and structure
The performance of obtained fire retardant eps foam heat preservation plate material is tested, as shown in table 4.
The performance parameter of 4A grades of eps foam sandwich color steel plate of table
Insulation board core material thermal coefficient of the present invention is lower than 0.045w/mk, and core material specific gravity can reach 80Kg/M3Hereinafter, core
10% deformation compression strength of material is greater than 200KPa, and calorific value is less than 3MJ/kg, reaches GB8624-2012 construction material combustibility point
A2 grades of Fire retardant grade requirements of grade.It is with sulfate liquor mix light calcined magnesia that this, which protects heat preservation adhesive mainly due to the present invention,
(MgO) powder, it is additional to solidify modifying agent, water-repellent modified dose, the air hardening that is combined of fire retardant, heat shielding additives and infrared light screening agent
The compound MgO-MgSO of property multiple element4-H2O inorganic fire keeps the temperature cementitious material, on the one hand the compound MgO-MgSO of the multielement4-
H2The magnesia inorganic fire heat preservation cementitious material of O air-setting contains 12% crystalline hydrate, when burning in the scene of a fire itself there is heat absorption to drop
Temperature effect, can play with flame-retardant system of the present invention and cooperate with flameproof effect, therefore be less than meeting A grades of EPS insulation board calorific values
When 3.0MJ/kg is required, needs the additive amount of fire retardant to be added and inorganic filler smaller, reduce the specific gravity of insulation board.It is another
The compound MgO-MgSO of air-setting multiple element that aspect is combined due to present invention fire prevention adhesive4-H2The heat preservation of O inorganic fire
Cementitious material itself compression strength is big, and the compression strength of 10% deformation of core material of the present invention is caused to be greater than 200KPa.
Due to not using fire retardant of the invention, thermal insulating filling and infrared light screening agent in comparative example 1, but only pass through
Sulfate liquor mix light calcined magnesia (MgO) powder is added, it is additional to solidify modifying agent, the water-repellent modified dose of air-setting being combined
MgO-MgSO4-H2O inorganic fire keeps the temperature cementitious material, due to not adding fire retardant and fire retarding synergist of the present invention, leads to plate ratio
Heavy and light and calorific value is higher is not able to satisfy A2 grades of calorific values less than 3MJ/kg needs.And the fire-retardant association of fireproof heat insulating adhesive of the present invention
The calorific value of polystyrene foam heat preservation plate material itself can have both been diluted with formula, while can also pass through the decomposition of fire retardant itself
Heat absorption is to offset calorific value, to make polystyrene foam heat preservation plate material of the invention that can reach A2 grades of heat under lower specific gravity
Value is less than 3MJ/kg requirement, and thermal coefficient is also due to inorganic filler additive amount is few and relatively low.
Comparative example 2, warm board core material thermal coefficient are lower than 0.063w/mk, and core material specific gravity can reach 120Kg/M3, core
10% deformation compression strength 135KPa of material, it is big compared with Insulation board core material thermal coefficient of the present invention, than great, and insulation board more of the present invention
10% deformation compression strength of core material is small.This is because comparative example 2 is prevented fires, adhesive uses 30% sodium silicate aqueous solution for glue
Glutinous agent, in the case where other are formulated constant situation with fireproof heat insulating adhesive of the present invention, since adhesive itself and flame-retardant system do not have
Synergistic fire retardation is played, when plate calorific value being caused to reach A2 grades of calorific values less than 3MJ/kg requirement, insulation board specific gravity is more of the invention
It is bigger than normal.And fireproof heat insulating adhesive of the present invention be with sulfate liquor mix light calcined magnesia (MgO) powder, it is additional cured modified
Agent, water-repellent modified dose, the compound MgO- of air-setting multiple element that is combined of fire retardant, heat shielding additives and infrared light screening agent
MgSO4-H2O inorganic fire keeps the temperature cementitious material, which contains 12% crystalline hydrate, sheet when burning in the scene of a fire
Body, which has with absorbing and cooling temperature effect with flame-retardant system of the present invention, cooperates with absorbing and cooling temperature effect, is meeting A grades of EPS insulation board calorific values
When being required less than 3.0MJ/kg, needs the additive amount of fire retardant to be added and inorganic filler smaller, reduce the ratio of heat preservation plate material
Weight, thereby reduces the thermal coefficient of insulation board.Additionally, due to sulfate liquor mix light calcined magnesia (MgO) powder of the present invention
The air hardening cementitious materials compression strength being combined into is big, and the compression strength of 10% deformation of core material of the present invention is caused to be greater than 200KPa,
Higher than the compression strength of 2 core material of comparative example, 10% deformation.
Embodiment 6, so that fire prevention adhesive only has flameproof effect, does not have due to being not added with heat shielding additives and infrared light screening agent
Have heat insulation function, cannot with eps foam plate play heat preservation cooperative effect, thus make preparation eps foam heat preservation plate material with reality
In the case of the same specific gravity of fireproof heat insulating adhesive for applying example 1~5, thermal coefficient is relatively large.
In terms of chromatic steel sandwich plate preparation, the present invention is by using flute profile side plate, flute profile sealing plate and upper and lower panel in structure
Integration combine, when sandwich color steel plate surface stress, since the integration at the edge of side plate, sealing plate, panel and core plate adds
Gu and the bathtub construction of side plate, sealing plate plays outer support frame, resisting when further improving sandwich color steel plate surface stress
Curved intensity；On the other hand due in the present invention core plate, side plate, sealing plate and upper and lower panel be combined into an entirety, a side
Face had both improved bending strength when sandwich color steel plate surface stress, while can also effectively solve existing chromatic steel sandwich plate bonding
