detailed description:
Detailed introduction
1. Product performance (also called: agricultural production system silicon modified acrylic elastic emulsion) polyacrylate elastic emulsion is an anionic emulsion copolymerized by acrylic ester and special functional monomer. This product is used for cement modification, production of cement-based polymer waterproof coating, elastic waterproof internal and external strong emulsion paint, waterproof mortar, and has good compatibility with cement. Its film has good extensibility, resilience, waterproof and good low-temperature flexibility, and has good alkali resistance and adhesion performance. It is suitable for preparing waterproof coatings or crack filling materials, and used for walls, Elastic waterproof of roof basement and toilet can also be used as anti crack agent of cement mortar.
2. Physical and chemical indicators:
Appearance: milky white viscous liquid with blue light
PH value: 5.5-6.5
Viscosity: 200-1000 centipoise
Solid content (53 ± 2)%
Calcium ion stability: excellent (10% CaCl2 liquid is randomly prepared)
Mechanical stability: excellent (2800 rpm, 20 minutes without demulsification)
Dilution stability: (10% aqueous solution does not delaminate for 96 hours)
3. Product characteristics
This product is used to produce polyacrylate * * * elastic waterproof coating for high elasticity and high water resistance internal and external wall emulsion paint for cement mortar modifier for cement mortar crack inhibitor
4. Storage and packaging
This product should be stored between 5-35 ℃ to avoid open storage and sunlight exposure. The reference mix proportion of polymer (polyacrylate emulsion) cement mortar is a highly elastic polyacrylate emulsion used for polymer cement mortar. Its dosage can be large or small, which is (8-100)% of the cement weight. The larger the dosage, the greater the water resistance, alkali resistance, flexibility, and solvent resistance of mortar or concrete, called polymer mortar or polymer concrete, The following table is the reference mix proportion table of polymer cement mortar recommended by the Ministry of Construction. Users can choose different dosage for different requirements of mortar or concrete products.

Anti corrosion materials: waste liquid trench, chemical plant floor, acid resistant tank, alkali resistant tank, septic tank, machinery and equipment foundation, chemical laboratory and drug warehouse floor, etc.
Polymer cement mortar has great development, mainly due to its excellent performance. Compared with ordinary cement mortar, polymer cement mortar has many unique advantages:
1. Good impermeability and compactness. Surfactant is added to polymer cement mortar to reduce water consumption, thus increasing compactness; In addition, after the internal polymer film is formed, the internal pores are blocked, which greatly improves the waterproof performance, improves the impermeability several times, and reduces the water absorption by 2-4 times.
2、
Crack resistance. Due to the internal polymer bonding, the crack resistance of polymer mortar is greatly improved. Someone has tested that the crack resistance of acrylic emulsion mortar is more than 10 times higher than that of ordinary mortar.
3. Cohesion force. During construction, the emulsion in the polymer mortar will have a layer of emulsion film with the surface of the object to be adhered. After drying, a layer of bonding layer will be formed. The adhesive force is very large, which can generally be increased by more than 2 times compared with ordinary mortar. The higher one can be up to several times.
4. The elastic modulus decreases and the deformation resistance increases. Polymer cement mortar was applied 70 years ago in foreign countries, and the 1960s was the most popular time for research and application. Rubber cement mortar was used earlier for bridge deck covering to prevent concrete corrosion caused by freezing and chlorine salt. In the early 1980s, 184 bridge decks in the United States were protected by polymer mortar, which had been used for more than 20 years. A dam in the United States was built in the early 1970s, and the ship lock wall was severely damaged, Then polymer cement mortar is used to repair, so that the project that originally needed years to repair can be completed within three weeks, and it is intact after winter freezing and thawing and ship collision tests.
