Abstract
The invention discloses a kind of preparation method of sol deposition hollow polystyrene building thermal insulation material, the present invention will be blended after hollow sol deposition pearl filler epoxidation with amination styrene monomer, in the polymerisation for participating in styrene, effectively raise compatibility of the filler between polymer, reunion is effectively reduced, the stability_intensity of finished-product material is improved.The composite of the present invention has good fire-retardant, insulation, anti-corrosion, stability_intensity etc., and light weight, and the feature of environmental protection is good, and combination property is superior.
Description
Technical field
The invention belongs to Material Field, and in particular to a kind of preparation of sol deposition hollow polystyrene building thermal insulation material
Method.
Background technology
Polystyrene foamed material is, using polystyrene resin as base-material, to add the auxiliary materials, heated hair such as foaming agent
The light material of bubble.It has that light weight, thermal conductivity factor are small, water absorption rate is low, water-fast, ageing-resistant, low temperature resistant, easy processing, valency
Honest and clean of fine quality the advantages of, but polystyrene foam heat insulation material is while the life given people brings huge facilitate, its is inflammable
Property also brings certain limitation to its application.Polystyrene foam is combustible material in itself, under fire and hot conditions
Easily decompose burning,
And produced with a large amount of poison gases.Therefore, it is badly in need of carrying out to grinding in terms of polystyrene foam heat insulation material fire safety
Study carefully work；
The purposes of foamed polystyrene resin widely, because it has high intensity, light weight, splendid insulation heat-insulating property
With high-selenium corn energy ability, the packaging of various instrument, valuables, precision instrument, vegetable and fruit and aquatic products etc. may be used as
Material；And because its have that pyroconductivity is low, water imbibition is small, electrical insulating property good, sound insulation, protection against the tide and moulding process it is simply etc. excellent
Good characteristic, and the insulation of industry is fished for and refrigerated in the roadbed laying and building construction and fishery for being widely used in road and bridge
In terms of material.Wherein, as a kind of excellent construction material, foamed polystyrene resin be mainly used in building roofing and
Wall, it has very good energy-saving effect as external heat insulating composite wall；And it is applied to house, work as heat insulation house surface
Factory, flat and pitch roofing, can play the effect such as sound insulation, dash steam, sealing and insulation.It is used as thermal insulating material for building
Material, several performance indications of overriding concern are low thermal conductivities, high fire retardancy, preferable self-strength；
At present, in order to improve the performances such as the fire-retardant of insulation material, self-strength, insulation, it will usually introduce inorganic filler, but nothing
The compatibility of machine filler and polymeric matrix is poor, is easily caused the stability reduction of finished product, and is passed through in Conventional insulation
Hollow glass micropearl can be often added, it has the heat-insulating property for improving material well, but its cost is higher, and fragile
Split.
The content of the invention
It is an object of the invention to the compatibility for inorganic filler in the prior art and polymeric matrix is poor, cost compared with
High the problem of, there is provided a kind of preparation method of sol deposition hollow polystyrene building thermal insulation material.
To achieve the above object, the present invention uses following technical scheme：
A kind of preparation method of sol deposition hollow polystyrene building thermal insulation material, comprises the following steps：
（1）Terephthalaldehyde, the methyl methacrylate mixing of 20-27 parts by weight of 1-2 parts by weight are taken, stirs, adds
Compound weight 30-40% methanol, is stirred, is sent in reactor, be passed through nitrogen, and 40-50 is incubated at 60-70 DEG C
Minute, obtain aldehyde radical monomer；
（2）Above-mentioned aldehyde radical monomer, the initiator mixing of 0.2-0.4 parts by weight are taken, the tetrahydrochysene of 6-9 times of compound weight is added to
In furans, it is sent in reactor, insulation reaction 6-7 hours at 80-85 DEG C, discharging is cooled to normal temperature, 45-50 DEG C of vacuum
Lower dry 2-3 hours, obtain aldehyde radical fluidized polymer；
（3）The tetraethyl orthosilicate of 17-20 parts by weight is taken, in the deionized water for being added to 30-40 times of its weight, 16-20 points of stirring
Clock, obtains precursor solution；
（4）The calcium carbonate of 20-30 parts by weight is taken, in the absolute ethyl alcohol for being added to 3-4 times of its weight, is stirred, 2-4 weights are added
The gamma-aminopropyl-triethoxy-silane of part is measured, ultrasound 20-30 minutes, are distilled off ethanol at 50-60 DEG C, obtain ammonification carbonic acid
Calcium；
（5）Above-mentioned aldehyde radical fluidized polymer, the mixing of ammonification calcium carbonate are taken, stirs, is added in above-mentioned precursor solution, be added dropwise
The 10-13% of 3-5 parts by weight ammoniacal liquor, rise temperature is 50-60 DEG C, and insulated and stirred 2-3 hours turns at 2700-3000 revs/min
Speed is lower to be centrifuged, and precipitation is washed, is dried 30-40 minutes at 70-80 DEG C of vacuum, obtains sol deposition polymer；
（6）Above-mentioned sol deposition polymer is added in the acetone of 10-13 times of its weight, 46-50 DEG C of thermostatted water is sent to
In bath, 10-13 hours are incubated, is discharged, filtering washs precipitation 2-3 times with acetone, deionized water, air drying, in obtaining successively
Empty sol deposition pearl filler；
（7）Take in above-mentioned hollow sol deposition pearl filler, the absolute ethyl alcohol for being added to 1.5-2 times of its weight, add 2-3 weights
The epoxychloropropane of part is measured, it is ultrasonic 10-20 minutes, ethanol is distilled off, the hollow sol deposition pearl filler of epoxidation is obtained；
（8）The lauryl amine of 4-5 parts by weight is taken, in the absolute ethyl alcohol for being added to 3-5 times of its weight, is stirred, rise temperature is
