Acrylic sealant, the sealant-containing methacrylic monomers, acrylate copolymers, benzoin propyl ether, α-methylstyrene oligomer and activating agents in a wide temperature range with good fluidity, good weather resistance when cured. Formula composition by mass of methyl methacrylate - methyl methacrylate, propyl methacrylate copolymer 220 500 α-methylstyrene oligomer, benzoin propyl ether 130 18 silica (0.025μm) 130 p-toluenesulfonyl chloride 2 is a flow of sealant or sealant squeeze amorphous material formulations to sell technology to fill a closed joint, can rely on embedded dry, temperature changes, solvent evaporation, stability and bond sealant technology formula chemical crosslinking materials and gradually the solid plastic, viscoelastic behavior or elastic sealing material molding. In order to ensure the sealing function, sealants should have the following basic characteristics: ① good filling them, squeeze construction sealant formulations advanced technology, storage stability, non-toxic or low toxic; liquid sealant formulations environmental technology, gas and other media ② low penetration; ③ can withstand telescopic movement, displacement and deformation of joints; cyclic deformation in the affected joints, ④ to ensure full recovery of its performance and shape sealant formulation technology, advanced technology sealant formulations, Jun Jun Feng Feng equipment provided by the device.
