FYT-1 polymer road and bridge specific waterproof coating

Description :

　　The bridge deck waterproof layer refers to a material layer designed to prevent rainwater from entering the bridge deck, rainwater, snow water from seeping into the bridge body, bridge, and other water sources from damaging the bridge body.

　　In recent years, the design standards and construction techniques of highways built in China have significantly improved overall. However, early damage often occurs within less than a year of opening, with water damage being the most harmful and common. For asphalt pavement, due to its high porosity and lack of waterproofing function, the infiltration and retention of water, under the combined effects of temperature and load, not only cause the surface layer to loosen, peel off, and pit damage, but also the infiltration of water will cause the base layer to soften and the strength to decrease, thereby inducing more serious damage to the surface layer. Similarly, cement concrete pavement also has similar problems. In addition, in road construction, various types of bridges account for a considerable proportion of the total mileage of the highway. In practical engineering, problems such as water seepage on the bridge deck of overpasses, peeling of pavement layers, and broken bridge decks often occur. Research has shown that water infiltration is one of the direct and significant causes of these damages. In order to protect the bridge deck, prevent ruts or tracks from directly wearing the bridge deck, and disperse the concentrated load of the wheels, cement concrete and asphalt concrete are usually used to pave the bridge deck. To meet the requirements of good waterproofing, stability, crack resistance, durability, and good interlayer adhesion, a waterproof layer is generally set between the bridge deck paving layers. There are many materials that can be used for laying waterproof layers in road and bridge construction, including various waterproof rolls, waterproof coatings, and various leak stopping materials. However, among numerous waterproof materials, waterproof coatings have been widely used and in large quantities in road and bridge waterproofing in recent years. This is mainly because waterproof coatings have the following advantages as road and bridge waterproofing: waterproof coatings are amorphous materials that can be applied to various shapes of substrates, forming a seamless and well integrated waterproof layer; Sprayable, easy to apply, high efficiency, water-based coatings can also be applied on damp substrates, which can shorten the construction period. Therefore, in recent years, with the vigorous development of highway construction, road and bridge waterproof coatings have also developed rapidly, and the engineering usage has increased year by year. However, due to the lag in standards, in the past, road and bridge waterproof coatings were mostly based on building waterproof coatings JC 408 and JC/T 894 standards. In fact, building waterproofing has significant differences in environmental and mechanical properties compared to road engineering waterproofing. The function of the bridge deck waterproof layer is different from that of waterproofing on buildings and structures in underground engineering. The roof waterproof coating is not subjected to load, its function is to prevent rainwater from entering the roof concrete, corroding the stressed steel bars in the concrete, and reducing the service life of the structure; The waterproof coating of underground structures is based on roof waterproofing and a constant water pressure; The waterproof materials used for roads and bridges are designed to provide waterproofing under constantly changing external strain and shear forces. In the early stages of construction, they must withstand the bare rolling of construction equipment and the piercing of granular materials. After opening for operation, they also have to withstand the repeated action of driving and dynamic water pressure. Especially for roads, they need to withstand large vehicle pushing loads and horizontal loads, and their strength is greater at bends. Due to the many curved and sloping bridges on highways, as well as the large gradient of the bridges and the high speed of heavy vehicles, some bridge decks have experienced asphalt concrete sliding after the construction and opening of bridges with waterproofing layers made of rolled materials. When the bridge is subjected to vibration loads, the waterproof layer of the bridge deck should be made of flexible coating and roll material. Compared with the two, the use of coating waterproof layer is better.

It can effectively prevent water infiltration and has strong adhesion with concrete, masonry, mortar plastering, etc. It is integrated with the substrate to achieve good waterproof effect.

　　2、 Product Details

　　Product Name: Shuanghong FTY-1 Bridge Deck Waterproof Coating

　　Product Model SH-114

　　Product form: single component, brown black liquid slurry

　　Execute standard JC/T975-2005

　　3、 Product advantages

　　1. The waterproof layer has fast film formation, good waterproof effect, and low price.

　　2. The construction process is simple, and it can be manually painted or mechanically sprayed. Both construction methods can achieve the same effect.

　　3. The waterproof layer has strong adhesion and shear resistance.

　　4. High temperature resistance, corrosion resistance, aging resistance, and long service life.

　　4、 Scope of application

　　The product is specifically designed for waterproofing engineering of roads and bridges, and is also suitable for waterproofing of building roofs, underground, and tunnel projects.

　　5、 Construction technology

　　1. Base preparation

　　(1) The substrate must be sturdy, flat, clean, and free of dust, grease, wax, release agents, and other debris;

　　(2) All small pores and sand holes can be sealed by adding a little water to the sealing king and mixing it into a wet ball shape, then smoothing it out;

　　(3) Before applying the slurry, the substrate can be pre wetted, but there should be no accumulated water.

　　2. Grassroots treatment: The newly constructed concrete shall reach the design strength, and the surface temperature cracks and natural shrinkage cracks shall be basically completed. The surface of the base shall be free of floating dust, dirt, grease, accumulated water, etc., and shall be clean and dry.

　　3. The construction must have complete equipment and good performance.

　　4. Mix the paint evenly before application, and maintain intermittent mixing during construction to prevent sedimentation.

　　5. Before applying a large area of paint, use a small brush to apply 2-3 coats on the treated substrate, and then apply a large area of paint. Generally, it takes 3-6 hours (but not more than 24 hours) depending on the temperature. After the paint is dry, apply the second and third coats until the desired thickness is achieved.

　　VI Precautions

　　1. This product is suitable for use in an environment between 5 ℃ and 35 ℃. During the construction process, it must be protected from rain, hot sunlight, and frost.

　　2. If there is precipitation, it does not affect the quality. Stir well and it can be used normally.
