Description

A kind of toughening modifying foam cement polyurethane foam composite insulation boards
Technical field
The present invention relates to building materials technology field, particularly relate to a kind of toughening modifying foam cement polyurethane foam complex heat-preservation Plate.
Background technology
Building Energy Conservation Policy and the enforcement of Building Fire Protection specification, promoted the fast development of wall heat insulation material.Polyurethane The organic insulation materials such as rigid foam plate, polystyrol plastic foam plate, phenolic foam plate, because of its insulation Excellent performance has obtained relatively broad application in building heat preservation engineering.The fatal weakness of polyurethane foam is exactly flammability Can, easily it is ignited, and combustion process release harmful gas.Even if with the addition of fire retardant also cannot fundamentally change this genus Property, the highest burning rank of polyurethane foam board for building also can only accomplish B1 level.Cement insulation board, expanded perlite The inorganic heat insulation materials such as warming plate, inorganic material parcel polyphenylene granule heat-insulating plate, can reach the A level of classification system for fire performance not Combustible material standard-required, have also been obtained the most universal application at building field, but owing to its thermal and insulating performance is less than having Machine insulation material, heat conductivity is 1.5-2 times of organic insulation material, and density is big, from great, along with China's building energy conservation requirement Step up, tend not to meet Current Building ' energy saving igniter requirement.Research and development are adapted to Current Building ' energy-saving design mark The building thermal insulation material of alignment request and fire safety rules has become current study hotspot.
In " preparation of foam cement/injection composite insulation boards and performance study " literary composition, using cement insulation board as One side template, in a mold injection foaming polyurethane material organic insulation material, heated, extrusion forming, formed after the demoulding and send out Soaked mud/injection composite insulation boards, cement insulation board is positioned at the outside of foam cement/injection composite insulation boards, flammability Can reach A1 level, when meeting fire heat, heat is concentrated mainly on this, does not have too many heat and enters into polyurethane insulation coating, energy Enough play fireproof effect.The composite insulation boards made has good fire protecting performance, and thickness is little, composite plate global density Low, reduce the energy consumption in production process, environmental protection and energy saving；But owing to foam cement layer is positioned at the outside of warming plate, light weight is many The feature in hole makes it have higher water absorption, and moisture content is the highest, and heat insulating ability is the poorest, and intensity is the lowest, which limits compound The application of warming plate, needs to be modified this.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of toughening modifying foam cement polyurethane foam Foam composite insulation boards.
The present invention is achieved by the following technical solutions:
A kind of toughening modifying foam cement polyurethane foam composite insulation boards, is made up of the raw material of following weight portion: waste and old Cotton fibriia 3-4, chlorinated paraffin 1-1.2, fatty alcohol-polyoxyethylene ether 0.3-0.34, superelevation thin portland cement 45-50, concentration For 30wt% hydrogen peroxide 3.5-4, Gypsum Fibrosum powder 3-3.5, stearic acid 2-3, aluminum sulfate 2.5-3, organosilicon breast 1.6-1.8, Lauxite 7-8, polyvinyl alcohol 1.5-2, glass bead 1.5-2, sorbester p17 0.6-0.8, deionized water are appropriate, polyoxypropylene polyol 75-80, isocyanates 23-25, pentamethyldiethylenetriamine 2.2-2.4, pentane 10-12, dimethicone 1.5-2, Gao Ju Ammonium phosphate 8-10.
Described a kind of toughening modifying foam cement polyurethane foam composite insulation boards, is made up of step in detail below:
(1) remove impurity in discarded cotton fibriia, and the chopped fiber being cut into 10 millimeter is stand-by；By chlorinated paraffin at 90-100 DEG C oil bath in heat 1-1.5 hour, be subsequently adding fatty alcohol-polyoxyethylene ether, after stir 30-40 minute, addition total amount 3-4 The deionized water of times amount, mixes with above-mentioned chopped fiber after being then cooled to room temperature, dispersed with stirring uniformly rear centrifugation, is dried, Obtain water-repellent modified reinforcing fiber；
(2) by the deionized water adding 2-3 times amount in Lauxite, stirring, to being completely dissolved, is subsequently adding polyvinyl alcohol, with The speed of 300-400 rev/min stirs 20-30 minute, adds glass bead, sorbester p17, continues stirring 10-15 minute, is changed Property Lauxite；
(3) deionized water of organic silicon emulsion with 25-28 times amount is mixed homogeneously, be subsequently adding the modified urea that step (2) obtains The water-repellent modified reinforcing fiber that the thin portland cement of urea formaldehyde, superelevation, Gypsum Fibrosum powder, step (1) obtain, added after the stirring 60-90 second Entering stearic acid, aluminum sulfate, adding concentration after continuing the stirring 60-90 second is 30wt% hydrogen peroxide, quickly after stirring 10 seconds after pour into mould Tool, band mould maintenance 24 hours after having got angry, then form removal, cutting, and within 28 days, obtain, with thin film parcel maintenance, the water that foams Mud；
(4) polyoxypropylene polyol is mixed with pentane, be subsequently adding pentamethyldiethylenetriamine and with its equivalent Deionized water, high ammonium polyphosphate, under room temperature, the speed with 800-1000 rev/min stirs the 100-120 second, is eventually adding remaining residue Composition, injects after the stirring 10-15 second in the mould that foam cement is a side template obtained with step (3), is 13-at pressure 16MPa, temperature is 40-50 DEG C of compacted under, and finally ripening 15-20 minute, the demoulding at 90-100 DEG C to obtain final product.
The invention have the advantage that the present invention will use foam cement as a side template, polyurethane foam is moulded in it Surface, during injection mo(u)lding, polyurethane compositions penetrates into the internal also solidifying and setting of cement insulation board, is formed good Combination interface, improve interface bond strength, and need not additionally add adhesive, energy-conserving and environment-protective, simultaneously because foaming water Mud layer is positioned at the outside of composite insulation boards, and when meeting fire heat, heat is concentrated mainly on this, does not have too many heat and enters into Polyurethane insulation coating, it is possible to play fireproof effect.Foamed cement material layer is as polyurethane foam insulation layer and the external world simultaneously Transition zone, play middle transition effect, reduce inside and outside temperature difference and dimensional stability problems, the Jin Erti of polyurethane thermal insulation board The total quality of high system.The present invention adds discarded cotton fibriia in the preparation of foam cement, by the process of chlorinated paraffin, Improve water resistance, further increase fire resistance, reduce the water absorption rate of foam cement layer, improve composite insulation boards Heat insulation effect, energy-conserving and environment-protective simultaneously, reduce production cost.
The present invention adds the Lauxite that the compositions such as glass bead are modified in the preparation process of foam cement, improves and sends out The comprcssive strength of soaked mud layer, toughness, reduce embrittlement, simultaneously because glass bead contains space, adds air content, Reduce the heat conductivity of foam cement layer, thus improve the performance of foam cement layer；The composite insulation boards made not only has There is the anti-flammability of excellence, the most solid tough.
