(2) put in screen cloth after hollow glass micropearl being dried, cross 300 mesh sieves, be subsequently adding the hydrogen of the 1mol/L of 10-12 times amount Sodium hydroxide solution, ultrasonic disperse 60-90 minute, it is heated to 90-100 DEG C, is heated to reflux 40-60 minute, washing and filtering is to pH value For neutrality, 70 DEG C of drying are stand-by；Adding Silane coupling agent KH550, n-propylamine in hexamethylene institute, the formation mixing that stirs is molten Liquid, then adds hollow glass micropearl in above-mentioned mixed solution, is heated to reflux 1-1.5 hour, uses deionization at 60-70 DEG C Water washs 2-3 time, filters, and dries at 80-90 DEG C, obtains modified hollow glass micropearl；
(3) kieselguhr being dried pulverizing, cross 300 mesh sieves, what the product then obtained with step (1), step (2) obtained changes Property hollow glass micropearl mixing, be sequentially added into triethanolamine, dibutyl tin laurate, distilled water and except diphenyl methane two Remaining residual components outside isocyanates, stirs 2-3 minute with the speed of 800-1000 rev/min, obtains 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.
The present invention also adds modified hollow glass micropearl in formula, and light weight density is little, and heat conductivity is low, pressure resistance Degree height, improves the compatibility of remaining foamed matrix, improves mobility and the processing characteristics of foaming system；The present invention makes Foamed glue can foam-in-place, have that uniform in foaming, cell density be big, the feature of low thermal conductivity, for switch cubicle or machine The intensity that is sealing adhesive of cabinet is big, good seal, excellent thermal insulation performance.
