TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The filler is active heavy calcium carbonate, active light calcium carbonate, heavy calcium carbonate, light calcium carbonate, talc powder, kaolin, and/or diatomite. The silicon dioxide is gas-phase silica and/or precipitated silicon dioxide. The fire retardant is magnesium hydroxide, aluminum hydroxide, antimonous oxide, red phosphorus masterbatch, resorcinol bis(diphenyl phosphate), melamine, melamine cyanurate, melamine phosphate, alkaline zinc carbonate, and/or zinc borate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The crosslinking agent is methyltrimethoxysilane, dimethyltrimethoxysilane, methyltriethoxysilane, polymethyltriethoxysilane, ethyltrimethoxysilane, diethyldiethoxysilane, vinyltrimethoxysilane, vinyltriethoxysilane, and/or tetraethoxysilane. The coupling agent is gamma -aminopropyltriethoxysilane, gamma -(2,3-epoxypropoxy)propyltrimethoxysilane, bis(3-trimethoxysilylpropyl)amine, or bis(3-triethoxysilylpropyl)amine. The catalyst is ethyl acetoacetate chelates of dibutyltin diacetate, dibutyltin dilaurate, dibutyltin oxide, isopropyl titanate, butyl titanate, or isopropyl titanate. The light stabilizer is any one or two of 4-benzyloxy-2,2,6,6-tetramethylpiperidine, hexamethylphosphoric triamide, and tris(1,2,2,6,6-pentamethylpepiridinyl)phosphite    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The viscosity of hydroxy-terminated polydimethylsiloxane is 700-200000, preferably 50-10000 cP. Preferred Process: One end of the connecting pipe used in step (B) is an internal thread structure matched with an adhesive discharge hole of the adhesive transmission pipeline of the gluing machine; while the other end of the connecting pipe is an internal thread structure matched with the adhesive tube. The adhesive tube comprises an adhesive nozzle, a pipe body, and a rear cover. The adhesive nozzle is an external thread structure. The pipe body and rear cover are both cylindrical; and the rear cover is capable of sliding in the pipe body. In step (B), the rear cover of the adhesive tube is directly pushed from the bottom of the pipe to the top of the adhesive pipe, the adhesive nozzle is provided at the adhesive discharge hole of the adhesive gun to start injecting adhesive, and then the rear cover moves backwards till the tail of the adhesive tube along with increase of sealant in the pipe.
