Waterproof means to avoid the leakage between the cracks or the joints of components caused by various factors. All buildings or structures in order to meet the function of moisture-proof, anti-seepage, anti leakage materials are called waterproof materials. The characteristics of waterproof materials belong to functional materials in building materials. The key purpose of building waterproof material selection is to prevent water, waterproof layer and leakage, especially in order to prevent leakage. Housing construction generally consists of flat roof, wall and shell, which are the key positions of waterproof engineering construction.
Classification of waterproof raw materials
According to the shape and shape of waterproof raw materials, the waterproof raw materials can be generally divided into four series of products: waterproof membrane, waterproof building coating, rubber seal and stiffness waterproof raw material. These four categories of raw materials can be divided into more than 100 categories according to their different composition.
Waterproof and waterproof membrane: asphalt waterproof membrane, asphalt concrete waterproof membrane, forming polymer material waterproof roll.
Waterproof building coating: asphalt concrete waterproof building coating, asphalt concrete waterproof building coating, polymer material waterproof building coating, concrete base waterproof building coating
Rubber seals: non shaped rubber seals, shaped rubber seals
Stiffness and waterproof raw materials: waterproof concrete, waterproof cement mortar, water reducing agent (waterproof agent, admixture, concrete expansion agent), waterproof and plugging raw materials
In addition, waterproof raw materials also have the trend of development in recent years, such as powder hydrophobic glass wool raw materials, concrete sealing waterproof agent and so on.
Characteristics of waterproof raw materials
1. It has excellent aging resistance, and has certain bearing capacity to light, heat and active oxygen.
2. It has waterproof layer penetration and corrosion resistance.
3. It has certain adaptability to the external temperature and external force, that is, the raw materials have high tensile strength and large tensile strength, and can bear the deformation caused by temperature difference transformation and various external forces as well as the expansion and cracking of rural grassroots. 4. It can not only maintain its own cohesive force, but also firmly bond with rural grassroots. In addition, there is a stable tensile strength under the aquiclude.
