POLYMER WATERPROOFING PASTE AND METHOD FOR ITS PRODUCTION Russian patent published in 2024 - IPC C09D125/10 C08L35/08 

FIELD: construction materials.

SUBSTANCE: invention relates to waterproofing construction materials. Invention discloses a polymer waterproofing paste containing, in wt.%, 15-17 of block copolymer of the styrene-butadiene-styrene linear type, 78-80 of petroleum toluene and 3-5 of polyvinyl butyral, and a method of producing the disclosed paste.

EFFECT: obtaining polymer waterproofing paste, which has increased relative strength, relative elongation at break, adhesion strength with metal, heat resistant, reduced water absorption, increased temperature range of operation to values of absence of cracks, and also during production, a simplified production technology is used, which requires less power consumption.
