GLUE COMPOSITION Russian patent published in 1995 - IPC

FIELD: glue production. SUBSTANCE: glue composition has, wt.-% 47-50% aqueous emulsion of copolymer of vinyl acetate, butylacrylate and acrylic acid 71.5-88.0; 50% polyvinylacetate dispersion 5-13; polyethylene oxide with molecular mass (0.5-2.0) x ± 1.5-3.0; 25% ammonium aqueous solution 1-2; ester phosphate plasticizer 0.4-1.2; barium sulfate 2.5-5.0; Trilon B 0.1-0.3, and water the rest. Properties: initial viscosity is retained for 180 days, thermal stability is up to 180 C, adhesion properties ( detachment strength of bitumen lining from the steel is 330-350 H/m at 25(0,5-2,0)·10⁶ 1,5-3,05 C; after holding under normal conditions for 180-200 days this value is 327-347 H/m, strength at uniform detachment is 0.26-0.35 MPa and 0.25-0.36 MPa, respectively). EFFECT: increased glue stability. 2 tbl
