Many people do not know much about building materials, and quick-setting rubber asphalt waterproof coating is one of the building materials. It is generally used when building a house. However, we are not very familiar with his characteristics. Today, Xiaobian will take a look at the advantages and disadvantages of spraying quick-setting rubber asphalt waterproof coatings and the characteristics of quick-setting rubber asphalt waterproof coatings!
Spraying quick-setting rubber asphalt waterproof coating features:
1, using spray technology, efficiency, to achieve a seamless connection, not drowning. It has unique features for objects with different shapes or shapes, and the construction is simple and convenient;
2. It has strong adaptability to the grassroots and can be used on base materials such as reinforced concrete, profiled steel, plastic and various masonry materials;
3, spraying surface treatment is simple, no special requirements can not do screed, in the case of humidity below 80% can be directly constructed;
4. During the construction process, it can work continuously, does not contain volatile organic compounds, is non-toxic and tasteless, has no exhaust gas emissions, does not pollute the environment, and can be applied to a confined space;
5. The coating has excellent weather resistance, acid and alkali resistance and aging resistance, and no need for a protective layer on the surface, which can effectively reduce the engineering cost;
6, the service life of more than 50 years, can be used in the environment of not less than 5 ° C, superior and excellent anti-peeling, anti-puncture ability;
Disadvantages of spraying quick-setting rubber asphalt waterproof coating:
It can be applied on a wet surface because it is water-containing, so it can be applied on a wet base. This is similar to polyurea because polyurea is rapidly solidified and can be solidified in a few seconds and ten seconds, so the permeability of the base surface is not particularly good, so we have a requirement, that is, The bonding strength of the base layer, unlike polyurethane, can be very high, generally around 0.5 MPa, which is also a weakness of it, that is, the bonding with the base layer is not very good. ? The strength is general, and it is not possible to make the roof waterproof with dynamic load.
Spraying quick-setting rubber asphalt waterproof coating characteristics:
1. Ultra-high elasticity: The elongation at break of the coating film can reach more than 1000%. It is suitable for expansion joints and deformation joints. It can effectively solve the leakage caused by stress deformation, expansion cracking, puncture or poor connection of various structures. , rust and other issues; effectively deal with structural deformation to ensure waterproof effect.
2, the overall waterproof: the coating film can perfectly cover the base layer, to achieve seamless connection of the coating, so as to meet the requirements of no water, no peeling. It is more convenient and reliable for the construction of the base structure with complicated structure or shape.
3, self-healing self-healing: high elasticity and high elongation make the self-healing function of the coating film, the general puncture can be repaired by itself, there will be no leakage.
4, good temperature resistance: coating film has excellent chemical resistance, acid, alkali, salt and chlorine, and high temperature and low temperature resistance.
5, the construction is simple: in addition to the main use of spray construction methods, brushing, scraping and other coating methods can also be used to meet the special requirements for waterproofing operations such as the water outlet, yin and yang angle, construction joints, structural cracks.
6. It can be applied on wet surface: It can be applied on the base surface of wet and clear water, which is convenient for application in subway, tunnel, water conservancy and other engineering fields.
The above are the advantages and disadvantages of the quick-setting rubber asphalt waterproof coatings introduced by Xiaobian today, and the characteristics of the quick-setting rubber asphalt waterproof coatings are here. I hope to help you to know about the spraying of quick-setting rubber asphalt waterproof coatings. friends. For more information, please stay tuned to the renovation home.
