Detailed description of the invention
Make insulation roof slab with the following methods:
(1) dispensing
High-strength alpha-type Gypsum Fibrosum: 26 parts, calcium-phosphate cement: 13 parts, flyash: 31 parts, rosin soap foaming agent:
2.5 parts, 107 glue: 0.25 part, glass fibre: 2.5 parts, water: 24.75 parts.
Raw material effect is as follows:
High-strength alpha-type Gypsum Fibrosum: high-strength alpha-type Gypsum Fibrosum system semi-hydrated gypsum, has the strongest hydrating capacity, at it and water
After mixing, first it is that high-strength alpha-type Gypsum Fibrosum dissolves the metastable saturated solution of formation, dihydrate gypsum in aqueous
Quickly at saturated solution crystallize, the crystallize of dihydrate gypsum, destroy the original poised state of semi-hydrated gypsum, can promote
It is made to dissolve further, until whole crystallizes are that dihydrate gypsum produces intensity.
Calcium-phosphate cement: the comprcssive strength of roof boarding is within the specific limits along with the increasing of calcium-phosphate cement percentage composition
Add and improve, the impact on roof boarding comprcssive strength of table 1 calcium-phosphate cement.Calcium-phosphate cement is worked as under experiment condition
When being 1:2 with plaster ratio, intensity reaches maximum.Then present along with the increase comprcssive strength of plaster ratio
Downward trend, owing to the increase of Gypsum Fibrosum percentage composition within the specific limits is conducive to tricalcium phosphate hydrated cementitious to generate
Hydroxyapatite, the rising of hydroxyapatite conversion ratio will cause the raising of its comprcssive strength；But when Gypsum Fibrosum excess
Time, wrap phosphate the most too much, suppressed it to change to hydroxyapatite, thus cause roof boarding
Comprcssive strength reduces.
The impact on roof boarding comprcssive strength of table 1 calcium-phosphate cement
| High-strength alpha-type Gypsum Fibrosum incorporation | Calcium-phosphate cement incorporation | Comprcssive strength |
| 24 parts | 10 parts | 19.8MPa |

| 26 parts | 15 parts | 23.9MPa |
Flyash: add flyash filler, plays a part deformation, increases intensity reduction cost, and flyash is
The fine powder collected from the boiler smoke of burning coal powder power plant, how spherical in shape its granule is, smooth surface, Lycoperdon polymorphum Vitt and
Lead.Its chemical composition is mainly SiO2、Fe2O3, CaO etc., the active SiO in flyash2With Ca (OH)2
Effect, generates the hydrated calcium silicate with the hydraulicity, thus improves goods hydrophobicity and intensity.
107 glue system water solublity and the high polymer of emulsion type or organosilicon, after adding in high strength gypsum Binder Materials
Gel precipitation and breakdown of emulsion is there is not, to the hardening of gypsum plaster without destruction in gypsum solution medium.
And the crosslinking of their own energy air hardening or cross-linked polymeric in acid medium, participating in Gypsum Fibrosum sclerous reaction process
In, CaSO can be coated with4Crystal, forms good protective layer, carries out certainly in the interstitial channels between crystal simultaneously
Exchange, blocks capillary channel, improves protection against the tide and the anti-condensation ability of gypsum plaster, the crosslinking of high polymer
Cohesiveness makes the intensity of goods also increase.
Rosin soap foaming agent: rosin soap foaming agent is internally formed bubble in calcium phosphate cement, these small gas
Bubble is wrapped up by calcium-phosphate cement, is evenly dispersed in calcium-phosphate cement slurry, forms stable foam calcium phosphate
Cement mortar, foam calcium-phosphate cement is starched and is not only wrapped up gypsum particle, and the space between filler particles, formed and protect
The temperature peculiar internal structure of composite light plate.
107 glue: 107 glue play reinforcing agent effect, 107 glue additions are the 0.5%～0.8% of Gypsum Fibrosum, add 107
Glue (polyvinyl formal resin) can significantly improve resistance to water and the intensity of goods, but dosage should be suitable, crosses and adds
Enter and affect intensity on the contrary.
Glass fibre: roofing thermal-insulating board mixes glass fibre, can improve roofing thermal-insulating board bending resistance, cracking resistance and resist
Impact flexibility performance, its character and consumption play decisive role for the mechanical property of wallboard.Table 2 is glass
The fiber impact on roofing thermal-insulating board intensity, shows in table that roofing thermal-insulating board bending strength is affected relatively by glass fibre
Greatly, relatively small on comprcssive strength impact, contrast volume is 2.5 parts and the mechanical index do not mixed, bending strength
Improving 50%, comprcssive strength improves 13.2%.Roofing thermal-insulating board bending resistance when the incorporation of glass fibre is less
Intensity increases with the increase of the incorporation of glass fibre, and when more than 2.5 parts, bending strength is not further added by,
This is owing to the contact condition of gypsum plaster Yu glass fibre is caused.It addition, after glass fibre excess,
Roof heat insulation sheet metal forming is relatively difficult.Considering, glass fibre volume is defined as 2.5 parts.
The impact on roofing thermal-insulating board intensity of table 2 glass fibre
| Glass fibre incorporation | Bending strength | Comprcssive strength |
| Do not mix | 5.6MPa | 22.8MPa |
| 0.5 part | 6.8MPa | 23.6MPa |
| 1 part | 7.3MPa | 24.1MPa |
| 1.5 part | 7.8MPa | 24.8MPa |
| 2 parts | 8.1MPa | 25.3MPa |
| 2.5 part | 8.4MPa | 25.5MPa |
| 3 parts | 8.5MPa | 25.8MPa |

High-strength alpha-type Gypsum Fibrosum, calcium-phosphate cement, flyash, rosin soap foaming agent, 107 glue are added water stirring 4～
6 minutes, stir speed (S.S.) was 60～110r/min.
(3) compression atomizing
Mixed liquor is loaded extrusion pump, utilizes extrusion pump by mixed liquor compression atomizing.
(4) injection
Sprayed by air-flow after glass fibre being cut to certain length by cutting spraying machine, then mix with atomization
Liquid spatial mixing and together spray fall and on mould, form goods bottom and surface layer, make glass fibre reach with base material
Preferably two dimension random distribution.

Spatial mixing together spray are fallen and are formed goods bottom and surface layer on mould, make glass fibre and base material reach preferable
Two dimension random distribution；
(5) intubate
Automatically combination core pipe is penetrated die cavity by tube filling machine；
(6) vacuum dehydration
Roofing thermal-insulating board carries out vacuum dehydration after completing operations for forming；
(7) tube drawing
Watering is used to extract in automatically sandwich layer compound being poured into die cavity；
(8) steam curing
Still is closed behind the door, cold sky in applying vacuum pump evacuation or top gas method to eject still when roofing thermal-insulating board enters still
Gas, slowly and equably heats up 1.5～2 hours, and in making still, pressure reaches 0.8MPa gauge pressure, temperature reach 125～
130℃.Keep temperature 125～130 DEG C 6～8 hours, the most slowly and equably release in still steam cooling 1.5～
2 hours, when in still steam pressure be down to its temperature of zero-pressure below 70 DEG C time, still door can be opened；
(9) demoulding
Through billet shift machine automatic demoulding after roofing thermal-insulating board hardening；
(10) milling
Use grinding machine that product surface is ground continuously, make product surface flatness and thickness error less than 1mm.
