Product overview
Acrylic copolymer emulsion is a kind of water dispersion of polymer, which is formed by adding cement and mortar then become a polymer cement mortar. It has excellent bond, anti-seepage, waterproof, anti-corrosion, anti-cracking, anti-freezing, anti-chloride ion penetration, anti-abrasion, anti-aging and etc. Suitable for waterproofing, anti-corrosion and repair of steel structures such as hydraulic, highway, tunnel, bridge, metallurgical, chemical, industrial and civil construction.
Advantages
* Nontoxic and harmless, non-polluting, meet the requirements of environmental protection
* Convenient construction, suitable for wet surface bonding
* Excellent bond properties: the bond strength with old mortar and steel plate is increased by more than 4 times, its elastic modulus and expansion coefficient are closer to the base concrete, and it is a very excellent new and old concrete bond and repair material.
* Strong impermeability: the compactness of acrylic emulsion mortar is much better than that of ordinary mortar, the resistance to chloride ion permeability is increased by more than 8 times, water permeability resistance is increased by more than 3 times , and the water absorption rate is reduced by 10 times in 2 days.
Application Range
* It is suitable for repairing dam overflow, erosion and freeze-thaw damage of hydraulic buildings, impervious treatment of concrete and reinforced concrete buildings such as roller compacted dam surface, tunnel and highway, bridge repair engineering.
* It is suitable for the application of steel bar corrosion prevention engineering. Protection against corrosion of seawater and chlorine salt, anti-carbonation treatment, anti-chemical corrosion.
* Leakage repair of basement, building surface, interior and exterior walls of civil buildings and kitchen, toilet and enclosed balcony, bonding of water plant, pool, filter plate.
* It can be used as interfacial agent.
Executive Standard JC/T 984-2011
Key points of construction
* Base surface treatment:Thoroughly remove dirt, dust and loose layer on the base surface and add sandblasting or artificial chipping to the base surface.
* Pre construction: Water should be sprinkled to keep the base surface in a saturated condition. To the general requirements, sand dust ratio is 1:2, and the amount of acrylic emulsion is 15-20% of the cement . To the high requirements for anticorrosion and impermeability , the sand dust ratio is 1:1 and the amount of acrylic emulsion is 25-30% of the cement.
* Configuration: When mixing acrylic emulsion mortar, mix the cement, sand first, then add water and acrylic emulsion, stir well, and the material must be weighed accurately. The mixing mortar will be used out in 30-45 minutes. The acrylic emulsion configure ratio is: acrylic emulsion: cement =1:1-1.5.
* Construction: Before applying acrylic emulsion mortar, brush a layer of acrylic emulsion paste as the base, brush thin and uniform, do not miss brushing, do not flow. Need to spread acrylic emulsion mortar before the paste is hardening. Use back and facade construction, when the coating thickness is more than 7mm, need 2 times screeding, so as not to fall off. After the mortar is spread, it will be compacted with force and next spread the surface. Smooth in the same direction, do not wipe it back and forth multiple times, and don’t need second times spread. When the repair area is large, can use blocks to separated for construction.
* Maintenance: Use sprayer to maintain or cover with film, pay attention to shade and heat preservation. Sprinkler maintenance 7 days and natural conservation 21 days can be put into use
