Description
technical field
The present invention relates to phenolic foam board technical field, particularly a kind of phenolic foam board that comprises nanoporous aerogel, also relates to the preparation method of described phenolic foam board.
background technology
Phenol formaldehyde foam due to its raw material be easy to get, inexpensive, be easy to produce, be conventional lagging material.Not too desirable but the problem of its existence is effect of heat insulation, the thermal conductivity of phenolic foam board is higher, the thermal conductivity of phenolic foam board is substantially in about 0.032W/ (m K) on the market, cause phenolic foam board and the heat-insulating property of the lagging material such as urethane aspect competitive pressure very large.And toughness is bad, drawing, compressive strength are also preponderated.Therefore, reducing the thermal conductivity of phenolic foam board, increase its toughness, is a main direction of phenol formaldehyde foam research.
Aerogel, English aerogel, is called again xerogel.Slough most of solvent when gel, make in gel content liquid than solids content much less, or the medium being full of in the space reticulated structure of gel is gas, appearance is solid state, and this is xerogel, also referred to as aerogel.The thermal conductivity of aerogel and specific refractory power are very low, and insulating power is also eager to excel 39 times than best glass fibre.Due to general in aerogel more than 80% be air, so there is extraordinary effect of heat insulation.In prior art, also there is the record that aerogel is improved to heat-proof quality for foam material, if China Patent Publication No. is in CN103408722A and CN103436006A, record respectively and used the polyurethane foam board of SiO2 airsetting rubber powder and nano titanium oxide, but also do not used it for the record in phenol formaldehyde foam.
summary of the invention
In order to solve the problem that thermal conductivity is higher, toughness is bad of above phenolic foam board, the invention provides a kind of intensity and oxygen index that phenolic foam board can be provided, reduce a kind of phenolic foam board that comprises nanoporous aerogel of thermal conductivity.
The present invention also provides the preparation method of described phenolic foam board.
The present invention is achieved by the following measures:
A phenolic foam board that comprises nanoporous aerogel, raw material weight proportioning is as follows:
Resol: emulsifying agent: toughner: whipping agent: nanoporous aerogel: fire retardant and solidifying agent weight ratio are 100:(1-10): (1-10): (7-12): (2-15): (2-15): (15-25);
Described toughner is that Polyvinylpyrolidone (PVP) and ethylene glycol are according to weight ratio 1:(1 ~ 5) be mixed to get.
Preferred described nanoporous aerogel is nanometer titanium dioxide silica aerogel, charcoal-aero gel, titania aerogel or alumina aerogels.
Preferred described whipping agent is lower boiling alkane,
Preferably polyethylene base pyrrolidone is more than one in K15, K17, K25, K30 and K90.
Preferably fire retardant is more than one in calcium hydroxide, magnesium hydroxide, aluminium hydroxide and silicon-dioxide.
Preferred described whipping agent is more than one in Skellysolve A, iso-pentane, normal hexane, pentamethylene and sherwood oil.
Preferred described solidifying agent is organic acid or mineral acid.
Preferred described solidifying agent is more than one in tosic acid, acid dimethyl, sulfocarbolic acid, sulfuric acid, phosphoric acid and hydrochloric acid.
Preferably described emulsifying agent is nonionogenic tenside.
The preparation method of described phenolic foam board, it is characterized in that nanometer titanium dioxide silica aerogel to be ground into powder, with resol, emulsifying agent, toughner, whipping agent, fire retardant, solidifying agent mixing and stirring, pour into fast in the mould of preheating and foam, solidify.
The resol using can be the normal resol using in foaming, also can be the low water absorption resol through modification, as phenol, formaldehyde, contain amino organic compound and organic phosphorus compound reacts under the condition of basic catalyst, obtain low water absorption modified phenolic resins.In a word, as long as can be used in the resol of foaming, can use in technical scheme of the present invention.
Described emulsifying agent, is selected from one or more in aliphatic alcohol polyethenoxy, polysiloxane, castor oil polyoxyethylene ether, polyoxyethylene nonylphenol ether, polyoxyethylene block copolymer, is all emulsifying agent conventional in resin expanded field.
Technical scheme of the present invention can reach the compressive strength and the pull strength that reduce the thermal conductivity of phenolic foam board, the water-intake rate that reduces phenolic foam board, increase phenolic foam board, and is strengthening to some extent aspect the flame retardant properties of phenolic foam board.Due to after airsetting rubber powder adds in resol, dispersed fine, interface compatibility is fine, and therefore surface tension is larger, and the intensity of phenolic foam board is increased.But, nano level aerogel is because particle is too little, inevitably cause aerogel to increase in the viscosity of sneaking into after modified phenolic resins, therefore need a kind of material that can reduce foaming system viscosity, therefore, this patent has been introduced a kind of special toughner Polyvinylpyrolidone (PVP) (PVP) and the mixture of ethylene glycol.
Toughner uses Polyvinylpyrolidone (PVP) (PVP) and ethylene glycol to mix in specific proportions, can further improve dispersiveness and the interface compatibility of nano-hole aerogel filler, further improves surface tension, and the intensity of phenolic foam board is increased.
Beneficial effect of the present invention:
Nano level aerogel is used as filler, then add special toughner, can improve the intensity of sheet material, compressive strength is brought up to more than 0.18 from 0.14 left and right; Pull strength is brought up to more than 0.12 from 0.07 left and right; The thermal conductivity that reduces sheet material, is reduced to below 0.022; Oxygen index brings up to 55 from 45 left and right.
