FIELD: chemistry. ^ SUBSTANCE: two-component sealing compound contains two components. The first component consists of a homogeneous polysulphide polymer based sealing paste. The paste contains filler in form of titanium dioxide, natural chalk and white soot, as well as epoxy resin and chloroparafin. The second component consists of a homogeneous vulcanising paste. The paste contains zinc oxide, manganese dioxide as a vulcanising agent, chloroparaffin, as well as titanium dioxide, natural chalk and white soot as filler, and diphenyl guanidine, thiuram as a vulcanisation accelerator and water. Before use, the first and second components are mixed with each other in ratio of 2:1 (pts.wt), respectively. ^ EFFECT: broader processing capabilities and low cost of the sealing compound. ^ 2 cl, 1 tbl |
