T/LFS 0002-2017 Spaying Quick-Curing Rubber Asphalt Waterproof Coating

Scope

Scope: This standard specifies the marking, requirements, test methods, inspection rules, labeling, packaging, transportation, and storage of spray-applied quick-curing rubber asphalt waterproofing coatings (referred to as SN waterproofing coatings). This standard applies to rubber asphalt waterproofing coatings used in construction projects, which are composed of two components: a rubber asphalt emulsion (component A) and a demulsifier (component B), and are applied by mechanical spraying for rapid demulsification and curing. Main technical content: 1. Appearance: After mixing, the A component should be uniform without color differences, gelation, or clumping, and without visible asphalt strands. The B component should not clump and should form a uniform and stable liquid after dissolving in water. 2. Solid content of the A component: The solid content of this standard product mainly refers to the rubber asphalt emulsion of component A. The B component is typically packaged in a solid form and dissolved in water for use, so the solid content only applies to component A. As a water-based coating, a higher solid content results in lower transportation costs. However, considering the feasibility and cost of the production process, the solid content should be controlled at an appropriate level. The verification test results show a value of (55~60)%, and the target value is set at 55%. 3. Gelation time: As a quick-curing material, the gelation time also needs to be considered to facilitate construction on irregular surfaces and vertical walls and reduce the requirements for surface flatness. It should be noted that...
