Description
Technical field
The present invention relates to the field of building materials, in particular to a kind of manufacture craft of flexible silicon ink alkene insulation board.
Background technique
With the raising year by year of energy conservation standard, external walls heating insulation has obtained significant progress, and becomes one Xiang Chong of China
The energy-saving building technology wanted.But in recent years external-wall heat-insulation material fall off and the Frequent Accidents such as fire, cause great personnel
Injures and deaths and property loss.With pushing forward comprehensively for building energy conservation, the especially fire safety problem of energy-saving building materials is also increasingly severeer.
Thermal insulation material used in exterior-wall heat insulation is broadly divided into inorganic heat insulation material and organic insulation material two major classes, but these materials at present
The shortcomings that generally existing energy conservation cannot take into account with fire prevention.The resistance to heat differential of organic material, easy firing, and big calorimetric is discharged in burning
It measures, generate a large amount of poison gas, can not only accelerate big fire spread but also be easy to cause trapped person and rescue personnel's injures and deaths.One
Denier meet fire will burn rapidly, and easily generate drip melt the case where, accelerate or sprawling.Then there is tensile strength not in inorganic material
Insulating layer caused by height integrally falls off, and thereby results in the accident of personnel, financial losses.
Graphite is a kind of infrared ray absorbing object that heat-insulating property is splendid, is made after graphite has been wrapped up outside granules of polystyrene
Thermal insulation material compare common EPS thermal insulation material and at least can be improved 30% in thermal insulation property, and there is water imbibition simultaneously
Low, the advantages that moisture permeable coefficient is low, dimensionally stable, high cost performance.But graphite polystyrene foam insulation board is due to its manufacture craft,
Cause its internal structure of a relatively loose, compression strength is not high, causes use scope limitation big, and tensile strength is inadequate, causes big
The problem of area falls off, and since its fire-protection rating is still B1 grades (fire retardant), it cannot be really achieved fire protection requirement, there are possibility combustions

Embodiment 1
The feedstock composition of embodiment 1 includes:
Silicoide, including 50 parts of active SILICA FUME, 5 parts of silica, 6 parts of glass bead and 50 parts of silica flour；
Binder, including 50 parts of cement, 30 parts of calcium oxide and 10 parts of flyash；
Mineral additive, including 105 parts and 5 parts of prodan of sodium metasilicate；
Additive, including 1 part of water-reducing agent, 2 parts of waterproofing agent, 2 parts of redispersable latex powder, 2 parts of cellulose ether, graphite
3 parts and 4 parts of foaming agent；
Reinforcing fiber is 1 part of short glass fiber in the present embodiment；
15 parts of graphite granules of polystyrene；
50 parts of water.
The manufacture craft of flexible silicon ink alkene insulation board of the invention is as shown in figure 3, firstly, make graphite granules of polystyrene one
Secondary foaming is allowed to swelling volume increase, and by setting steam pressure, keep its close by heating graphite granules of polystyrene
Corresponding variation occurs for degree, to reach required density requirements.Steam pressure is set as 0.2MPa, and temperature sets 100 DEG C, once
The time of foaming is 10 seconds, then pressure maintaining 30 seconds, is then depressurized 3 seconds.
Then, sodium silicate solution, silica flour, calcium oxide, cement and prodan is taken to fill under the conditions of 20 DEG C of set water temperature
Divide stirring, sequentially adds flyash, active SILICA FUME, cellulose ether, short glass fiber, water-reducing agent, waterproofing agent, can divide again
Scattered latex powder, graphite, foaming agent carry out stirring in 5 minutes, and (mixing time is adjusted accordingly according to temperature change, blender revolving speed
It is set as 300 revs/min), stir evenly its whole as premixing cementitious material.The addition of sodium metasilicate can be such that mixture has
Fire protecting performance.The addition of the materials such as graphite can be such that the mixture presetting period is gradually shortened, and reduce mixture mobility, main to make
With to promote bending property, enhance finished product compression strength and bend resistance intensity.Meanwhile reducing thermal coefficient enhancing heat insulation effect.
Then, graphite granules of polystyrene is added in a mixing bowl, is put into the progress of premixing gel rubber material after starting blender
It is mixed, sufficiently mixes it uniformly.By multiple repetition test, speed of agitator need to be set in 100 revs/min, stir 5 points
Clock, revolving speed is too fast or mixing time is too long can be such that graphite granules of polystyrene shrinks, deformation.
(1mm heavy sheet glass will be padded in mold in mixture (containing graphite granules of polystyrene) the input mold after stirring again
Paper demoulds convenient for the later period), mold is as shown in Figure 1, include upper layer mould 1 and lower layer's mould 2, upper layer mould 1 and lower layer's mould 2 are stacked, warp
Feedstock composition after crossing stirring is input in mold, is tentatively fixed to the feedstock composition of plate in mold, mold it is interior
Chamber is adjustable in a thickness direction.It is shunk since certain proportion can be generated after material heating pressurization, finds, press after test of many times
For product thickness 5cm, the height of level-sensing device need to be adjusted to 10cm, shrinkage rates 45%.And to guarantee that mixture inputs mould
Non-uniform phenomenon is avoided to generate during tool, the ratio that transmission speed should be set in 1 minute 1m is best.
Before mold enters flattening bench 3, flattening bench 3 is preheated with oil temperature machine.Then upper layer mould 1 is removed, will be loaded
There is lower layer's mould 2 of the feedstock composition of plate to move into flattening bench 3 as shown in Figure 2.There are multiple stacked heating in flattening bench 3
Plate 4, the initial void between every two heating plate 4 are all larger than the sum of the height of feedstock composition of lower layer's mould 2 and plate.Work as temperature
Mold is pushed by degree after reaching setting value, and upward with oil hydraulic cylinder 5, two neighboring heating plate 4 can relatively move, so that
Gap between every two adjacent heating plate 4 synchronously reduces, so that the feedstock composition of each plate is synchronously squeezed, when
Stop mobile heating plate 4 when feedstock composition is expressed to a certain amount of in a thickness direction, reaches the temperature inside feedstock composition
To 65 DEG C, the pressure inside feedstock composition is made to reach 0.1MPa, keeps forming for pressure 8 minutes, during heating pressurization,
Second time of foaming occurs for graphite granules of polystyrene.Oil temperature machine is then shut off by its natural cooling depanning.
Finally, carrying out fog room maintenance to the product after depanning, fog room is dry, divulges information, and curing time is 7 days.
Gained sample is through detecting, compression strength 0.250MPa, and the tensile strength perpendicular to plate face is 0.182MPa, curved
Bent deformation values are 3.010mm, and thermal coefficient is 0.0580W/ (mK), and sample combustibility rank reaches A2 grades.
