Abstract: PURPOSE: A quencher and a foam compound for injection are provided, to remove the light of the surface of foam effectively, to improve the dimension stability and to enhance the tear strength, the split tear strength and the adhesive strength of a quencher by employing the silica whose surface is modified from hydrophilic one to hydrophobic one. CONSTITUTION: The quencher comprises 100 parts by weight of silica; and 1-10 parts by weight of a silane-based coupling agent for modifying the silica. Preferably the silane-based coupling agent is selected from the group consisting of vinyl trichlorosilane, vinyl tri(2-methoxyethoxy)silane, vinyl triethoxysilane, vinyl trimethoxysilane, 3-methacryloxypropyltrimethoxysilane, 2-(3,4-ethoxycyclohexyl)ethyltrimethoxysilane, 3-glycidyloxypropylmethyldiethoxysilane, N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, N-2-(aminoethyl)-3-aminopropylmethyldimethoxysilane, 3-aminopropyltriethoxysilane, N-phenyl-3-aminopropyltrimethoxysilane, 3-mercaptopropyltrimethoxysilane and 3-chloropropyltrimethoxysilane. The foam compound comprises 100 parts by weight of 100 parts by weight of a base; 1-10 parts by weight of the quencher; and 0.25-1.5 parts by weight of polyethylene glycol or diethylene glycol as a crosslinking stabilizer.
