Description
Technical field
The invention relates to a kind of heat-insulating fireproof material, especially a kind of exterior-wall heat insulation fire retardant material and preparation method thereof.
Background technology
Propose the idea of development of " Sustainable development ", " saving renewable resources ", " building a harmonious society " since China after, environment protection, energy-saving and emission-reduction, weather-proof safety are just really by implementation.State Environmental Protection Administration, firmly build section dwelling house, office, commercial establishment are implemented to force insulation.At present wall heat insulation material is take polystyrene and polyurethane foaming material as main, this material thermal conductivity reaches 0.04w/m.k, heat-insulating property is poor, particularly aspect fire resistance, show extremely outstandingly, polystyrene belongs to the material that can discharge a large amount of toxic gases after inflammable and the burning, in recent years cause a lot of malignant fires, therefore adopt hardly this material at developed country's building energy conservation heat insulations such as America and Europes.Because in recent years continuously many lagging materials, the finishing material building fire that causes not up to standard, country unprecedentedly strengthens the fire resistance attention degree of material of construction.In view of the severe situation of Building Fire Protection, it is the material of A level that the Ministry of Public Security requires the covil construction lagging material must adopt combustionproperty, in the field of businessly causes huge vibrations.Therefore develop a kind of heat preservation energy-saving and the good external wall decorative material of flame retardant properties is very necessary.
Summary of the invention
The object of the invention is to overcome the prior art deficiency, a kind of heat preservation energy-saving, fire-retardant, lightweight, novel external wall finishing material that cost performance is high and preparation method thereof are provided.Purpose of the present invention realizes by following technical proposals, the present invention by following component by weight mix successively, plastotype forms again: expandable heat-reactive phenolic resin 60-70, the linear urea-formaldehyde resin 30-40 of thermoset, tween 80 3-8, silica powder 10-30, aluminium hydroxide micropowder 10-15,4A zeolite 10-20, Skellysolve A 5-12, vitriol oil 2-6.
The production method of product of the present invention is as follows:
The linear urea-formaldehyde resin 30-40 of expandable heat-reactive phenolic resin 60-70 weight part and thermoset weight part is inserted in the reactor and was stirred 10-20 minute; Then add tween 80 3-8 weight part, stirred 10-20 minute; Add simultaneously again silica powder 10-30 weight part, aluminium hydroxide micropowder 10-15 weight part, 4A zeolite 10-20 weight part, stirred 20-30 minute; Add again Skellysolve A 5-12 weight part, stirred 5-10 minute; Add at last vitriol oil 2-6 weight part, stir and stop after 2-5 minute stirring, this material is injected box mould, insulation is aging 9-12 hour in 70-80 ℃ of situation, is cooled to room temperature and namely makes this product.
Product of the present invention is by bi-component resin, composite flame-retardant agent, solidifying agent, foam stabilizer, whipping agent, media assemblage.Bi-component resin refers to the mixture of expandable heat-reactive phenolic resin and the linear urea-formaldehyde resin of thermoset, and resol has preferably fire-retardant heat insulation performance, but exists fragility large, and percentage of open area is high, easily efflorescence, the shortcoming that physical strength is low, price is high; Urea-formaldehyde resin low price, hard, scratch resistant, has certain toughness.The present invention is composite by resol and urea-formaldehyde resin, and in conjunction with both advantages, the product of making is a kind of obturator-type rigid foam, and smooth surface, intensity is good, cost performance is high.Composite flame-retardant agent refers to the mixture of aluminium hydroxide micropowder (D50 particle diameter 1-2 micron) and 4A zeolite (D50 particle diameter 1-2 micron), and the aluminium hydroxide micropowder molecular structural formula is Al(OH)
3, containing the crystal water about 35% in the molecular structure, it is 350 ℃ that product begins dehydration temperaturre; 4A zeolite molecules structural formula is Na
12AL
12Si
12O
4827H
2O, contain the crystal water about 21% in the molecular structure, it is about 450 ℃ that product begins dehydration temperaturre. aluminium hydroxide micropowder (particle diameter 1-2 micron) and 4A zeolite (particle diameter 1-2 micron) decomposite the water vapour non-flammable gas when being heated, produced strong thermo-negative reaction, absorb the part heat that burning is emitted, reduce the temperature on combustiblematerials surface, effectively suppress the generation of inflammable gas, stop spreading of burning; And decomposite the water vapour non-flammable gas, the concentration of the inflammable gas that combustiblematerials is decomposed out waters down below the burning lower limit; The effect that also oxygen concn in the combustion zone is had simultaneously dilution stops proceeding of burning, reaches fire-retardant effect.Aluminium hydroxide micropowder (particle diameter 1-2 micron) and 4A zeolite (particle diameter 1-2 micron) use and discarded process in all unharmful substance discharge, and can also in and the acidity and the corrosive gases that produce in the combustion processes, the solidifying agent that the present invention adopts is sulfuric acid.The foam stabilizer that the present invention adopts is tween 80.The whipping agent that the present invention adopts is Skellysolve A.The filler that the present invention adopts is silica powder (200-250 order).
Product of the present invention is insulated fire sound-proof material of new generation, it have lightweight, fire prevention, chance naked light do not burn, smokeless, nontoxic, without drippage, use temperature is enclosed extensively (196～+ 300 ℃), does not shrink under the low temperature environment, the characteristics of not embrittlement.Because the product rate of closed hole is high, thermal conductivity low (can be lower than 0.028w/mk) then, heat-proof quality is good, and has good water resisting property and aqueous vapor perviousness, is good heat insulating energy saving material, especially the desirable thermal insulation material of HVAC refrigeration engineering.During the product pyrolytic decomposition, the gas that overflows is nontoxic, tasteless, and is all harmless to human body, environment, meets the national green environmental requirement.
Product oxygen index of the present invention 〉=55%; Water-intake rate≤2%(soaked 24 hours); Thermal conductivity is between 0.02-0.029 w/mk; Product stability, weather resisteant are good; Nonpoisonous and tasteless, environmental protection.This product is very good fire prevention, thermal insulation, environment-friendly and green thermal insulation decorative material energy-conservation, attractive in appearance.Product is by national fire-proof construction material quality supervision and test Spot detection, and the goods combustionproperty reaches GB8624-2006 " material of construction and goods classification system for fire performance " standard A level.
The physical and chemical index of product of the present invention is as follows:
1, product oxygen index 〉=55%;
2, water-intake rate≤2%(soaked 24 hours);
3, thermal conductivity 0.02-0.028 w/mk;
4, proportion≤80kg/m
