Elastic polymer cement waterproof coating is prepared by modifying special cement with high-durability polymers, supplemented by a variety of additives, and using a specific process. This material not only has the advantages of high strength and good durability of cement-like inorganic materials, but also has the good elasticity and waterproof properties of rubber-like materials. After coating, it can form a high-strength, tough and durable waterproof coating film, and can be used according to engineering needs. Formulated in various colors. After testing by the National Building Materials Testing Center and provincial and municipal quality inspection stations, this product meets the requirements of relevant standards, and its technical performance has reached the first-class level of similar products in the world. It has been successfully used in many key and large-scale projects and has received unanimous praise from users. .
2. Technical Features
Good integrity, the entire waterproof layer is integrated in one go, without seams, which reduces the risk of leakage and improves the waterproofing effect (thick cured coating, under high water head pressure Impermeable)
, excellent elasticity and flexibility, the elongation at break is adjustable within % according to engineering needs, and has the ability to withstand building settlement, dry shrinkage, high and low temperature deformation without cracking
, breathable and impermeable, the water vapor in the building structure can evaporate slowly and naturally through the waterproof layer, and the hollowing phenomenon of conventional waterproof materials (such as rolled materials) is not easy to occur
, and has extremely strong bonding force with each substrate, and its The bonding strength is about twice that of ordinary cement mortar
. Cold work construction, it can be painted directly on the wet base surface without baking the base surface, which does not delay the construction period. The construction operation is simple and flexible
and anti-freeze. It has excellent melting, high temperature resistance, corrosion resistance, ultraviolet radiation resistance, weather resistance and aging resistance. It can be used as exposed roof waterproofing
, non-toxic, non-polluting, no organic solvent volatilization, safe construction and harmless to the human body. It is a green and environmentally friendly product
. When leakage due to human factors occurs, the leakage point can be directly found and partial repair is required. Compared with repairing with roll materials (easy to hollow out), it saves time, effort, and Save money. , it can be mechanically pumped or manually operated during construction, without the need for vibration or troweling. It is convenient and fast, has low labor intensity and sets and hardens quickly. It has high early strength and final strength. The hardened ground is smooth and beautiful, does not shrink and crack, and is wear-resistant and water-resistant. protrude. When in use, mix this product with water in a certain proportion and pour it on the ground to form a smooth and smooth ground layer.
3. Technological Advancement
Compared with similar products currently on the market, the performance of the new generation of elastic polymer cement waterproof coatings in all aspects, especially water resistance and weather resistance, has been greatly improved. It has the following characteristics: less polymer dosage, low ash-to-ash ratio, high elasticity (elongation at break %), and high modification efficiency (polymer-injected cement waterproof coatings are generally two-component, and the liquid material is water-based Polymer dispersions and powders are mainly composed of cement, fillers, and admixtures. The two components are blended and constructed on site. Currently, the polymer cement waterproof coatings on the market use a ratio of liquid powder, and liquid powder, also That is to say, the amount of powder and cement used is more, that is, the ash collection ratio is lower, but the elasticity is higher than the former)
Compared with similar products currently on the market, the water absorption rate is greatly reduced (coating The average water absorption rate of the film is .%, but only .%. The water absorption rate of the coating is .%, but only .%), high water resistance, no swelling when soaked in water, and high retention of tensile strength and elongation at break after immersion
It is mainly based on inorganic substances such as cement (inorganic substances account for % of the total system, and organic substances only account for %). In this way, a large number of cement-based materials can effectively shield ultraviolet radiation and moisture intrusion. In addition, high-quality materials are used. Durable polymer (with annual application examples) does not use non-cross-linked polymers with poor water resistance and aging resistance, so it has better UV resistance and superior weather resistance and aging resistance.
To sum up, the comprehensive technical performance of the product is at the leading domestic level and it is an ordinary replacement product.

Suitable for various waterproofing projects, such as roofs, interior and exterior walls, basements, toilets and bathrooms, kitchens, tunnels, subways, pools, dams, roads, bridges and other engineering waterproofing curves and special shapes Waterproofing treatment of structures, nodes, complex parts, etc.
Used as interface treatment agent, the bonding strength is three times higher than that of ordinary cement mortar. It is used to bond marble, ceramic tiles and other veneer decoration materials, and to bond the joints of cement pipes. Bonding material, etc.
Used in repair projects, such as the repair of various cement products and concrete water pipes, the repair of defects or cracks in masonry structures and old buildings, especially under dynamic loads and vibration conditions (such as roads, Repair of bridges, etc.
The waterproof layer can be made into various colors, integrating waterproofing, decoration, insulation (combined with insulation materials) functions
Concrete protection, such as anti-carbonization, anti-salt water corrosion, etc.
. Mix this product into putty according to the liquid and powder materials, which can be used for jointing or sealing projects.
6. Construction methods
Selection of product models and applicable project parts
In order to achieve reasonable technical and economic effects, different types of products should be selected according to different parts of the project, such as roofs and exterior walls. , deformation joints and other parts with large deformation, it is better to choose high elasticity products (liquid, powder, water); while basements, toilets, bathrooms, tunnels and other engineering parts have smaller deformation, so low elasticity products should be chosen. (liquid, powder, water), construction cannot be carried out below ℃ or in the rain.
This product is a two-component product. When using, add the liquid material first, slowly add the powder material while stirring, and stir thoroughly until there are no lumps in the material. The stirring time usually takes about 10 minutes. Filter the slurry (filter out the unstirred material pieces), and then divide Apply to full thickness and become waterproof once cured.
