High-polymer waterproof roll material preparation technology
The invention discloses a high-polymer waterproof roll material preparation technology. The high-polymer waterproof roll material preparation technology includes the steps of adding asphalt modifiers as heavy as 5-15% of the weight of dehydrated liquid asphalt into the dehydrated liquid asphalt, stirring for 0.5-2 hours, turning on a colloid mill to circulate for 2-4 hours, adding talcum powder as heavy as 40-50% of the weight of the dehydrated liquid asphalt, mixing and stirring at the temperature of 150-180 DEG C for 1-3 hours and decreasing the temperature to 100-120 DEG C so as to obtain liquid asphalt paste; adhering high-polymer plastic sheets with high-polymer filament irregular polyester fabric by means of mixing, hot melting and cooling so as to obtain a carrier sheet, spraying the obtained inorganic filler asphalt paste on one non-fabric surface of a high-polymer carrier and covering the rubber asphalt liquid surface with a film prior to primary cooling and secondary cooling so as to enable the carrier to be cooled and sized. The high-polymer waterproof roll material preparation technology has the advantages that a product prepared by the technology only needs single-surface coating and is simplified in structure, light, less prone to deformation, excellent in waterproof and corrosion-resistant performance and highly resistant to puncture of plant root systems, and elongation at break can exceed 400%, so that tensile strength and tear resistance are improved.
