Scope

Scope: This document specifies the product classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of floor coatings specifically designed for hazardous waste storage sites. This document applies to low-volatile organic compound (VOC) content floor coatings primarily made from synthetic resins, pigments, and fillers. These products possess special functions such as anti-seepage, chemical resistance, and anti-static, and are suitable for coating cement mortar, concrete, and other substrates on the floors of hazardous waste storage sites, providing protection against seepage and corrosion. This document also applies to floor coatings on cement mortar and concrete substrates in hazardous chemical production sites. Main technical content: 5.1 Requirements for hazardous substance limits: The VOC content shall comply with the requirements for floor coatings in Table 2 of GB/T 38597-2020, and the content of other hazardous substances shall comply with the requirements in Table 5 of GB 30981-2020. 5.2 Performance requirements: 5.2.1 Requirements for primers and intermediate coats: The performance of primers and intermediate coats shall comply with the requirements in Table 1. Table 1: Performance indicators for primers and intermediate coats Item Indicator Primer Intermediate coat State in the container after stirring No hard lumps Drying time/h Dry time ≤ 4 Full dry time ≤ 24 Workability No obstacles to film formation Surface smooth, no visible shrinkage holes Alkali resistance (saturated calcium hydroxide solution, 48 h) Film intact, no bubbling or peeling allowed, slight discoloration acceptable Adhesion (pull-off test)/MPa ≥ 2.0 --- 5.2.2 Requirements for topcoats and composite coatings: The performance of topcoats and composite coatings shall comply with the requirements in Table 2. Table 2: Performance indicators for topcoats and composite coatings Item Indicator Topcoat
