I. Introduction acrylic waterproof coating (858,951 series of water color multifunction waterproof coating) is a single component, water-based acrylic waterproof coating, this coating with pure acrylic emulsion and multiple polyacrylic acid emulsion as the base material, adding a variety of additives and inorganic fillers dispositions. After the coating can form tough, flexible waterproof adhesive force strong film, combined with the grass-roots form a rigid complete waterproof system to adapt to all kinds of deformation structure, to the role of long-term water impermeability. This product can be made from a variety of colors as needed. Second, product characteristics: 1, direct construction of the base surface wet or dry variety of materials. 2, the coating toughness, high strength, water resistance, good low temperature, anti-aging properties. In particular, the superior general waterproofing products in the UV aspect. 3, strong bond, good extension, color optional. Four, one-component, simple construction, short construction period. 5, non-toxic, tasteless, is frequently used alternatives currently polyurethane coating, SBS and other solvent-based paint waterproof paint. 6, plus a variety of colors, can be used for decorative waterproof coating. Third, the scope: This product is widely used in-situ concrete roof, walls, asbestos cement tile roof, interior, bathroom, storage and other parts of the water, moisture, renovation of old buildings face trap and so on. Layers can also be used to protect other waterproof layer. Fourth, the main technical indicators: Standard: JC / T846-2000 "building waterproof coating polymer emulsion" technical indicators technical indicators Ⅱ type Ⅰ Solid content (%) ≥65 dry time (h) ≤4 drying time (h) ≤8 Tensile strength (Mpa) ≥1.0 ≥1.5 elongation at break (%) ≥300 ≥300 low temperature flexibility (around φ10mm stick) -10 ℃ -20 ℃ No crack No crack impermeability (0.3Mpa , 30min) impermeable impermeable five, construction methods: 1, primary treatment: primary firm, firm, smooth, no sharp corners, no rust, oil and obvious water damage. Yang angle using cement mortar or sealant made of rounded, Yin angular diameter should be greater than 50mm, the angular diameter of the sun should be greater than 10mm. Cracks and pipe groove root leaving in the grassroots should be filled, sealed material handling. 2, the primary treatment agent: To improve adhesion, the general should be brushing primary treatment agent. Primary treatment agent can be diluted with water waterproof coating method for site preparation, proposes to add water to 50% is appropriate. Special grass can be used for supporting primary treatment agent. Primary treatment agent with about 0.3kg / m. 3, waterproof coating: 1.5mm ~ 2mm thick film should be 3 to 4 times brushing film, be painted over after each drying again (usually intervals of 6 to 12 hours), brushing direction perpendicular to each other. For overlay when the carcass reinforcement material, the matrix material should be flat, without wrinkles and soaked film thickness under the carcass should not be less than 1mm, the film thickness should not be less than 0.5mm. 4, the amount and thickness: the amount of 1.5kg / ㎡ ~ 4.0kg / m, 1.5 mm thick film coatings need about 3.3kg / m. Six, packaging, transport and storage: a product in a clean, dry, airtight plastic bucket, packaging capacity of 5kg / drum, 20kg / barrel. 2, according to the non-dangerous goods transport requirements. Transportation, to prevent rain, exposure, extrusion, collision, upside down, keep the packaging intact. 3, the product should be stored in ventilated, dry, cool place, to prevent direct sunlight. Storage temperature should not fall below 0 ℃. Valid for one year
