BRS acrylic emulsion (acrylic emulsion) Mortar

I. Introduction of acrylic emulsion mortar waterproofing preservative is acrylic emulsion waterproof emulsion, special cementitious materials, high quality aggregates are mixed in a special process in which acrylic emulsion polymer molecule is a modified base polymer waterproofing preservative systems; long acrylic emulsion waterproof / corrosion mortar life, convenient construction, long-term immersion in water life of more than 50 years. The mortar has excellent adhesion, crack, antifreeze, seepage, corrosion, resistance to chloride ion penetration, abrasion resistance, aging properties, suitable for water conservancy, port construction, highways, bridges, metallurgical, chemical, industrial and civil construction and other seepage, corrosion protection of steel surfaces and repair works and reinforced concrete structures. Second, the use of 1, structural concrete reinforcement, waterproof plugging two air defense facilities, dams, ports seepage treatment 3, hot tub, landfills, chemical storage, chemical tank and other chemical resistance building 4, pavement , bridges, tunnels, culverts, concrete repair 5, industrial and civil roof, bathroom, basement seepage prevention treatment for 6, 7 waterproof steel and reinforced concrete, direct construction in the wet base surface, and a variety of substrates with good The bond strength. Third, the technical indicators (see the implementation of standards: GB / T50212-2002) 1, acrylic emulsion latex performance indicators: No. Project standard indicators tested index Results 1 Viscosity 11.5 ~ 12.5 (25 ℃, pa s) 12 First grade 2 Total solids content 39-4140 First grade 3 density ≥1.056 1.06 First Class 4 Storage stability 5 ~ 40 ℃, 3 months, no significant precipitation (when the temperature is too large or the temperature is too low, there will be a slight layering, using Stir required) 5 Appearance Milky white uniform emulsion Note: The total solids content of acrylic emulsion due to the synthesis method and purity are not the same, for high temperature polymer purity of greater than 99 or more, a total solids content of more than 20% to meet the with performance of product requirements. 2, acrylic emulsion waterproof / corrosion mortar performance index Project Quality index Index Initial setting time (min)> 45 300 Final setting time (h) <12 10 28d Compressive Strength (MPa) ≥30 40 28d flexural strength (MPa) ≥3.0 4.5 28d and cement mortar bond strength (MPa) ≥1.2 1.5 28d impermeability grade (MPa) ≥1.5 1.7 28d Water absorption (%) ≤5.5 3.5 Alkali resistance: saturated Ca (OH) 2 solution, 168h without cracking , peeling no cracking, spalling heat resistance: 100 ℃ water, 5h no cracking, spalling no cracking, spalling frost resistance: -15 ℃ ~ + 20 ℃, 25 times without cracking, spalling no cracking, spalling 28 d shrinkage / % without cracking, spalling no cracking, spalling Note: The setting time can be adjusted according to user needs; impermeability grade of mortar test block measured. Fourth, the construction Introduction 1, the conditions of use 1.1 acrylic emulsion mortar construction environment temperature is preferably 10-35 ℃, when the environmental temperature is below 5 ℃, heat insulation measures should be taken. Construction should not be in the wind, rain, or direct sunlight high temperature environments. 1.2 acrylic emulsion mortar curing period should not be less than the cement mortar or concrete base 3d construction. 1.3 When purchased separately acrylic emulsion lotion, from the time the construction site with mortar: cement grade should not be less than p.o42.5 of cement, aggregate of not more than 2.5mm use clean sand or quartz sand, cement: sand ratio 1: 1-2, one ton of acrylic emulsion mortar dosage of 38-50, in order to achieve the appropriate mortar product performance and construction for better operability, may be added stabilizers, defoamers, ph value regulating agents additives. 1.4 When you use the finished mortar, acrylic emulsion dosage will be reduced, the minimum can be as low as 15-20% by weight of the mortar 2, the base surface treatment: 2.1 primary surface should be smooth, rough, clean, no oil, sand, empty drums, cracks and other phenomena. Construction of high-pressure water rinse before application and keep moist state, do not have time during the construction of the water on the steel construction 2.2 interface, the primary surface should be free of grease, rust, rust grade appropriate for ST3, welds and lap joint, application of gamma After milk mortar, during construction. 3, the preparation of mortar: acrylic emulsion water corrosion mortar should adopt artificial mixing, when using mechanical mixing, use the vertical double mixer. When not mixing with vigorous agitation; mix well, then stir again not adding water, configured mortar should be used within 1h. 4. Use these steps: 4.1 acrylic emulsion mortar shop wiping should be preceded by brushing propyl emulsion cement paste again, according to the cement paste 100-200: acrylic emulsion mixing ratio of 38-50, according to the construction of the need to join some modified agents, while brushing the side paving propyl emulsion cement mortar. If the base surface rough, smooth, to meet the conditions of the construction can also be directly applied to water corrosion with a good acrylic emulsion mortar. 4.2 Mortar a construction area should not be too large, should striping or block staggered construction, each area should not be greater than 12m2, the bar width of not more than 1.5m, fill joints or segmented construction staggered intervals of not less than 24h. Slope of the seams of wood or PVC strips should be pre-fixed on the base until after plastering mortar can stay out of strip joints and fill joints after 24h. Layered construction, the left seam location should be staggered. 4.3 propyl emulsion cement mortar after Paving pressure immediately after wiping, and should once disappearing, should not be repeated wiping pressure. Bubble punctured should meet the pressing, the surface should be dense. 4.4 Construction on the facade or on his back, when the face layer thickness is greater than 10mm, should be layered construction, layered plaster thickness is preferably 5-10mm. Pending before a layer of dry to sticky layer can be under construction. 4.5 acrylic emulsion waterproof mortar after 12-24h after construction, it should be on the surface and then brushing a layer of cement paste. 5, after curing acrylic - emulsion cement mortar surface, dry surface that is covered with plastic film spray or when to tack, sacks conservation. Plastic film four weeks should seal conservation cycle preferably wet curing 7d, then nature conservation 21d. 6, when the material used for laying blocks, 6.1 blocks surface water should be pre-soaked wood blocks 2h, dry water stains can be paved. 6.2 bonding layer material thickness and width mortar joints should meet the following types of block material combined with a layer thickness (mm) mortar joint width (mm) acid brick / temperature 4-64-6 natural stone tile thickness ≤30 6-8 6 -88-15 thickness> 3010-158-15 6.3 paving bricks acid should be used for kneading extrusion method; paving thickness is greater than or equal to 60mm natural stone base slurry method may be employed. 6.4 laying in the grass on top of the block material should be brushing paste edge paving, block material of the bonding layer and the mortar joints should be dense and full, and shall take measures to prevent the continuous paving block material movement, the height of the facade of the block material should be clay, mortar setting time to adapt, and should prevent bulk compressive deformation. Shop 6.5 blocks material, mortar joint should fill compaction, mortar joint surfaces should be smooth and should block material to clean the excess mortar. Fifth, packaging storage 1, the product packaging specifications 20kg / barrel or 50kg / drum, dry mortar in accordance with 25kg / bag. 2, should be stored indoors in a dry, ventilated, moisture, rain environment, the shelf life of six months. 3, acrylic emulsion mortar waterproof non-toxic, tasteless, non-radiation, environmental compliance, according to general cargo storage and transportation thereof.
