PREPARATION OF LIQUID RUBBER UTILIZED IN CONSTRUCTION ENVIRONMENT
Journal Title: Topics in Civil, Environmental & Building Engineering (TICEBE) - Year 2017, Vol 1, Issue 1
Abstract
Sealing material liquid rubber utilized in construction environment was prepared using diphenyl methane diisocyanate (MDI), polyether 330, polyether 220, butyl acetate, additives andfillers and so on.The influencesof the temperature of prepolymerization reaction, the content of –NCO after prepolymerization reaction, the ratio of mixed polyether, and the amount of catalyst and fillers on product properties were investigated.The optimal preparation technology was determined. the results show that, when the temperature of prepolymerization reaction is 90℃, polyether 330 / polyether 220 is 85 /15 (w %), the content of – NCO (w%) is 4. 1%, the amount of dibutyltin dibutyl (w %) is 0. 3 %, and the amount of packing (w %) is 4%, the liquid rubber prepared has better properties. It exhibits good waterproof performance when utilized in construction environment.
