Abstract

The invention relates to a nano-filler modified bi-component polysulfide hollow glass elastic sealant. It is characterized in that the elastic sealant consists of an A component composed of liquid polysulfide rubber, first plasticizer, filler, nano-filler and coupling agent, and a B component composed of oxidizer, second plasticizer, pigment and accelerant. Preparation method of the elastic sealant includes adding the liquid polysulfide rubber, the first plasticizer, the nano-filler, the filler and the coupling agent into high-speed dispersion machine, heating, stirring, vacuumizing, stirring at 600-800 r / min for 180 min when degree of vacuum achieves 9 MPa, and controlling sealant temperature below 85 degrees, to obtain the A component; and uniformly mixing the oxidizer, the second plasticizer, the pigment and the accelerant on tri-roller grinder until obtained mixture is uniform and fine, and degassing, to obtain the B component. The invention has good ultraviolet ray resistance, and has properties satisfying operation requirements of hollow glass.

Description

technical field [0001] The invention relates to an elastic sealing material for the second sealing of hollow glass (energy-saving glass), in particular to a nano-filler modified two-component polysulfide elastic sealant for hollow glass. Background technique [0002] At present, polysulfide sealant is the most widely used sealing material on insulating glass for doors and windows. The existing polysulfide sealant for insulating glass still has insufficient anti-ultraviolet performance. The current formula is mainly composed of the following materials: A component, liquid polysulfide rubber, butyl benzyl phthalate, calcium carbonate; B component, manganese dioxide, carbon black, butyl benzyl phthalate, accelerator and so on. According to the ratio of A:B=10:1, the hollow glass sample is made by mixing evenly. After 14 days of curing under standard conditions, it is placed on the roof. After a year of sunlight, wind and rain, cracks will appear on the surface of the glue. Th...
