Abstract

The invention relates to a flame-retardant two-component polysulfide rubber elastic sealant for hollow glass, and its preparation method. Component A includes liquid polysulfide rubber, plasticizer, filler, flame retardant, and coupling agent; and is obtained by adding the materials into a high-speed dispersing machine, heating, stirring, vacuumizing to 0.09 MPa, and stirring at 600-800 rpm and at rubber temperature of below 85 DEG C for 180 min. Component B includes antioxidant, plasticizer, color masterbatch, flame retardant, and accelerator; and is obtained by mixing the materials on a three-roller mill, milling uniformly, and degassing. The inventive sealant has good flame-retardant fireproof property, and various performances satisfying application requirement 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 flame-retardant two-component polysulfide elastic sealant for hollow glass and a preparation method thereof. Background technique [0002] At present, polysulfide sealant is the most widely used sealing material for insulating glass in doors and windows. The existing polysulfide sealant for insulating glass generally uses: A component, liquid polysulfide rubber, butyl benzyl phthalate or Chlorinated paraffin, calcium carbonate, etc.; B component, manganese dioxide, butyl benzyl phthalate or chlorinated paraffin, carbon black, accelerator, etc. Liquid polysulfide rubber, butyl benzyl phthalate, and carbon black are extremely flammable in a fire. Chlorinated paraffin has a certain flame retardant effect, but it will release chlorine gas when it burns, which is harmful to human body and is generally used less. Therefore, ...
