911 waterproof coating polyurethane waterproof coating inquiry

Waterproof coating (also known as polymer waterproof slurry, polymer waterproof glue) is an acrylic polymer cement-based waterproof material of high performance; it is composed of acid and alkali, anti-aging, high elasticity of the acrylic polymer copolymer emulsion formed add other additives; by adding a certain percentage of cement can be formulated to suit the different parts of the waterproof coating. Second, product characteristics 1. Cost-effective: strong bond, good weather resistance, high temperature resistant, cement-based waterproof layer formed by mixing with cement, long life waterproof. 2. Strong adhesion to the substrate: according to a certain proportion of cement mixing, may be applied to the wet surface of the base, after hard work and the substrate to form a watertight whole, without hollowing, shedding phenomenon of channeling water. 3. Construction is simple: the addition of a special polymer slurry modified active substance can be mixed directly with concrete or cement mortar construction, and excellent compatibility. 4. Environmental: The product is non-toxic, harmless, non-polluting, below the national focus on the promotion of environmentally friendly products. Third, the scope 1. Ⅰ polymer cement-based waterproof coating: mainly used to make the roof waterproof layer or high performance occasions extended waterproofing. 2. Type Ⅱ polymer cement-based waterproof coating: mainly used for basements, underground tunnels, bathroom, pool, etc., under construction and in particular long-term immersion in water and wet conditions. 3. Ⅲ polymer cement-based waterproof coating: mainly used for making facade tiles need to paste the parts of the waterproofing. Fourth, the technical indicators of the implementation GB / T 23445-2009 "polymer cement waterproof paint" standard indicators. No. Test Item Standard I II III 01 solid content,% ≥70 02 Tensile strength, Mpa ≥1.2 ≥1.8 ≥1.8 03 Elongation,% ≥200 ≥80 ≥30 04 bond strength, Mpa ≥0.50 ≥0.70 ≥ 1.00 05 impermeability (0.3MPa, 30min) impervious Fifth, use the base 1. The base surface treatment surface clean, leveling, keeping no cracks, no loose; yin and yang angle arc angle made; the sharp local mill level. 2. The polymer cement-based waterproof coating formulation Ⅰ polymer cement-based waterproof coating ratio (weight ratio): liquid material: 32.5R than ordinary Portland cement = 1: 0.5; type Ⅱ polymer cement-based waterproof coating ratio (weight ratio): liquid material: 32.5R than ordinary Portland cement = 1: 1; Ⅲ polymer cement-based waterproof coating ratio (weight ratio): liquid material: 32.5R than ordinary Portland cement = 1: (2-2.5). 3. parts processing node splash wet base surface, the yin and yang corner, wall pipe, floor drain port, construction joints, etc. with type Ⅱ polymer cement-based waterproof coating and fiberglass cloth to strengthen the process, a thickness of about 1.0mm. The waterproof layer brushing predetermined proportion reclaimers, thoroughly stirred with a stirrer for about 5 minutes, until the coating material does not contain aggregate, for water, the first compound in liquid water, stirring with a stirrer slowly add the powder. Increase the amount of color pigment layer coating liquid material is 10% or less, and only need to add the pigment in the surface layer of paint. Even when applied to try to not have local deposition and require multiple brush several times so as not to leave air bubbles between the paint and the grass roots, tightly bonded. When adding non-woven construction, coating and the coating to be under continuous construction, nonwovens straight to paving, and not leave with a brush real hollowing. The first layer of non-stick directly to brush a second layer (each about 0.6mm, not too thick) after hand; general water need to brush two or more, the last time when the waterproof layer is dry dilute sprinkle sand on top, can increase their and the protective layer adhesion. After brushing the edge of the coating brush a few times to close the head; waterproof layer is completely dry. 5. waterproof protective layer waterproof layer after dryness can do 1.5 to 2.0cm thick protective layer of cement mortar in accordance with demand. 6. Reference amount: Ⅰ polymer cement-based waterproof coating thickness of 1.0mm, about 0.8 ~ 1.0kg / m2. Type Ⅱ polymer cement-based waterproof coating thickness of 1.0mm, about 0.6 ~ 0.8kg / m2. Ⅲ polymer cement-based waterproof coating thickness of 1.0mm, about 0.4 ~ 0.6kg / m2. VI Cautions 1. Stir the paint, one-time run, should not be re-used rubber dryness. 2. Suitable construction temperature 5 to 45 degrees Celsius, air circulation during the construction. 3. After two days of construction, attention to anti-rain, strong sun or frost; tools and equipment after use please clean water. Seven, packaging and storage of 50 kg / barrel, 25 kg / barrel, 20 kg / barrel, 9 kg / barrel; cool place, the shelf life of six months.
