The invention relates to elastic grouting water-stop glue. The invention relates to a
polyurethane hot melt adhesive which comprises the following components in percentage by weight: 40%-41% of polyether
polyol, 7.3%-7.7% of polyphenyl polymethylene polyisocyanate, 26%-28.5% of
plasticizer, 23.5%-24.5% of filler, 0.2%-0.4% of
pigment and 0.2%-0.6% of
antioxidant. The
plasticizer is prepared by mixing four of dioctyl
phthalate, diisooctyl terephthalate, dinonyl
phthalate, butyl benzyl
phthalate, di-sec-octyl phthalate,
fatty acid methyl ester, acetyl
tributyl citrate,
tributyl citrate and chlorinated paraffin; the
plasticizer is prepared by mixing four of dioctyl phthalate, diisooctyl terephthalate, dinonyl phthalate, butyl benzyl phthalate, di-sec-octyl phthalate,
fatty acid methyl ester, acetyl
tributyl citrate, tributyl citrate and chlorinated paraffin; the
antioxidant is formed by mixing one or two of octadecanol
propionate, bis (stearoyl) thiodipropionate, bis (cinnamoyl) thiodipropionate and polysiloxane; the
antioxidant is formed by mixing one or two of octadecanol
propionate, bis (stearoyl) thiodipropionate, bis (cinnamoyl) thiodipropionate and polysiloxane; the filler is formed by mixing one or two of
calcium carbonate, diatomite, talcum
powder and carbon
fiber; the
pigment is formed by mixing one or two of
carbon black and
graphite.
