Description

The flame retardant polyurethane foamed glue that a kind of air-tightness is good
Technical field
The present invention relates to foamed glue technical field, particularly relate to the flame retardant polyurethane foamed glue that a kind of air-tightness is good.
Background technology
Dual-component polyurethane adhesive is a most important class in adhesive for polyurethane, generally by component A (host) and B group Dividing (firming agent) composition, wherein component A is hydroxy component, and B component is containing free isocyanate groups component, and the two is separately packed, Use can be prepared by a certain percentage.In China, the research of expansion type dual-component polyurethane adhesive starts from nineteen ninety-five, 20th century 90 Later stage in age gradually comes into operation.Expansion type dual-component polyurethane adhesive has that porous, relative density be relatively low, specific strength relatively High, according to the difference of raw material and formula can be made into common soft bubble, hard bubble, high rebound foam and low resilience urethane foam resilient foam etc., Multiple application necks such as automobile, electronics, rack, filter, three-prevention lamp, explosion-proof casing, household electrical appliance are widely used in it Territory.Therefore, the promotion prospect of expansion type dual-component polyurethane adhesive is the most optimistic.The present invention is directed to it at switch cubicle, rack The application of the aspects such as sealing is studied.The effect of the shell such as switch cubicle or rack avoids internal unit by extraneous factor Interference, but only shell is not enough to stop outside dust storm or electromagnetic radiation, therefore, it is desirable to and sealing strip increases product integral sealing Performance.Conventional seals technique is to use physical bonds method that standard seal part is bonded in sealing station, and the method exists production Efficiency is low, poor reliability, many defects such as unsightly.
With trihydroxy polypropylene oxide ether, Oleum Ricini and two in " preparation of expansion type dual-component polyurethane adhesive " literary composition Methylenebis phenyl isocyanate is primary raw material, and glycerol is chain extender, and water is foaming agent, by suitable proportioning, uses pre- Poly-method has synthesized a kind of expansion type dual-component polyurethane adhesive, the foaming adhesive foam uniform and smooth made, tensile shear Intensity is higher, and combination property is more excellent, but its heat resistance is poor, easily burns, when being used as the sealing of switch cubicle or rack, no Can meet the safety used, this is accomplished by carrying out its heat stability strengthening modification, improves fire resistance.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that the flame retardant polyurethane foaming that a kind of air-tightness is good Glue.
The present invention is achieved by the following technical solutions:
The flame retardant polyurethane foamed glue that a kind of air-tightness is good, is prepared by the raw materials in: diphenylmethane diisocyanate Ester 150-160, trihydroxy polypropylene oxide ether 100-105, Oleum Ricini 100-110, glycerol 5-6, diethyl phosphate 40-43, The sodium hydroxide solution of 1mol/L is appropriate, kieselguhr 13-15, distilled water 5-6, triethanolamine 2-3, dibutyl tin laurate 3- 4, stearic acid 2-3, polyvinyl alcohol 3-4, cetomacrogol 1000 2-3, short glass fiber 4-5, nanoclay 2-3, silane coupled Agent KH560 0.8-1, dehydrated alcohol are appropriate.
The flame retardant polyurethane foamed glue that described a kind of air-tightness is good, is made up of step in detail below:
(1) pouring in reactor by trihydroxy polypropylene oxide ether, Oleum Ricini and glycerol, water bath with thermostatic control is heated to 85-90 DEG C, Stir reaction 60-90 minute with the speed of 150-200 rev/min, be then cooled to 40-50 DEG C, be slowly added dropwise diethyl phosphate, Add in 30 minutes, drip complete, be warming up to 70-75 DEG C, react 2-3 hour, the sodium hydroxide of the complete 1mol/L of question response It is 7 that solution is neutralized to pH, at 55-60 DEG C of decompression dehydration;
(2) short glass fiber is pulverized, mix with nanoclay after crossing 300 mesh sieves and put into mixing and ball milling 30-40 in ball mill Minute, it is subsequently adding and is dissolved in the silane coupler KH560 of 2-3 times amount dehydrated alcohol, cetomacrogol 1000, be heated to 50-60 DEG C, Continue ball milling discharging after 40-60 minute, obtain mixed material;
(3) kieselguhr being dried pulverizing, cross 300 mesh sieves, it is mixed that the product then obtained with step (1), step (2) obtain Compound material mixes, and is sequentially added into triethanolamine, dibutyl tin laurate, distilled water and removes methyl diphenylene diisocyanate Outside remaining residual components, stir 2-3 minute with the speed of 800-1000 rev/min, obtain compound A;
(4) use scene that compound A is heated to constant temperature 30 DEG C at foamed glue, be subsequently adding methyl diphenylene diisocyanate, Quickly mixing, after being stirred the 15-20 second with motor stirrer with the speed of 300-400 rev/min, is coated onto workpiece table by compound Face, is heated to 25-30 DEG C so that it is foam voluntarily, then dry tack free, it is achieved foam-in-place molding, obtains foamed glue.
The invention have the advantage that the present invention passes through trihydroxy polypropylene oxide ether, Oleum Ricini compounds with glycerol, by stirring Mix the NCO that mixing can be free with B component and crosslink reaction, generate stable three-dimensional-structure;In reaction system Middle interpolation diethyl phosphate, can improve the oxygen index (OI) of system, coordinates diatomaceous interpolation, improves the anti-flammability of system further Can, and along with diatomaceous interpolation, the abscess of foamed glue becomes more tight, reduces its heat conductivity so that it is have good Good effect of heat insulation;The present invention also adds a certain amount of triethanolamine and dibutyl tin laurate in course of reaction so that it is Form composite catalyst system, each reaction in system is carried out catalytic action thus reaches the foamed state of balance;Present invention profit With distilled water as foaming agent, do not use organic solvent, safety and environmental protection, good appearance, foam uniform and smooth, viscosity can be formed Moderate, flame retardant effect is excellent, is prone to the foamed glue that the tensile shear strength after coating, and solidification is higher during use.
Glass fibre, nanoclay, Polyethylene Glycol are added by the present invention by the compounding mixed material of making of certain technique In foamed glue system, import long flexible ether linkage, thus improve the toughness of foams, by synergism, can be notable Improve the compressive strength of foamed glue, heat stability and anti-flammability, reduce pulverization rate and shrinkage factor, and improve foam structure, Improve the sealing property of foamed glue;The foamed glue that the present invention makes can foam at the scene, has backfilled enclosed effective, construction Simply, the feature such as safe and reliable, low cost, great be widely applied prospect.
