1. What is a silicone water repellent?
Silicone waterproofing agent is a non-polluting, non-irritating new high-efficiency water guard material for the world's in advanced countries are widely used. Silicone waterproofing agent sprayed (or brushed) on the surface of the material, can be formed on the surface of a layer of colorless transparent, UV-resistant breathable film imperceptible to the naked eye, when the rain blowing on it or when the humid air, the water droplets will naturally flow, to prevent the intrusion of water.
Silicone waterproofing agent has two properties, respectively, water-based and oil-based. Water-based silicone waterproofing agent is colorless or light yellow, and it is mixed into the cement mortar, but also can play the role of a retarder, water reducer, and reinforcing agent. Therefore, it is suitable to be used in the construction industry, exterior wall finishes, underground engineering, antique buildings, pools, masonry, cement, gypsum products, and perlite as the main material of thermal insulation materials and rural roof waterproofing, moisture-proof, anti-pollution treatment. Oily silicone waterproofing agent is transparent, generally used for glazed surfaces, ceramic tiles, floor tiles, ceramics, etc., and can be appropriate to add part of the solvent dilution, easy to use.

2. What are the special features of silicone water repellent?
(1) Differences in chemical properties
Silicone waterproofing agent is a silicone high molecular polymer with a large number of organic groups in the molecular chain, which has excellent weather resistance, high temperature resistance, corrosion resistance, and chemical resistance, and shows an excellent waterproofing effect in the field of waterproofing.
Inorganic silicone waterproofing agent is made of water glass as the main raw material, does not contain organic groups, with a certain degree of durability and weather resistance, but in chemical environments and high temperature conditions of poor stability.
(2) The waterproofing principle is different
Silicone waterproofing agent can apply the maximum repellency principle is to using its molecular chain of organic groups and the substrate material to produce affinity, forming of hydrophilic and lipophilic surface, thus forming a layer of waterproof protective layer.
Inorganic silicon waterproofing agent is formed through the reaction with the substrate material in the Ca2 or Mg2 and other metal ions, in the substrate material to generate a gel layer on the surface, the formation of chemical reaction waterproof layer.
(3) The scope of application is different
Silicone waterproofing agent for the construction of roof waterproofing, basement waterproofing, tunnel waterproofing, bridge waterproofing, highway waterproofing, and so on. Inorganic silicon waterproofing agent for the construction of waterproofing of external walls, indoor waterproofing, pond waterproofing, ditch waterproofing, and waterproofing of underground buildings. Because the organosilicon waterproofing agent has excellent temperature resistance, corrosion resistance and chemical resistance, and other characteristics, so in the industrial field in wastewater sewage treatment, petrochemical, and other important areas of waterproofing.
3. What about the structure of silicone water repellent?
Silicone waterproofing agent is a heavy-duty water repellent, non-toxic, and in line with the concept of green development, with excellent comprehensive characteristics, and thus, its application prospects are promising. This is mainly due to the main chain of silicone polymers being usually interactively ordered -Si-O - links, molecular side chains containing different carbon atoms of alkyl, amino, and carboxylic acid groups, etc., mainly. Generally speaking, in the application, the main chain of its molecules in the silicon oxygen atoms due to the strong electronegativity and close to the surface of the material into a film, on the contrary, the side chain will be away from the surface layer arranged in the periphery of the performance of different roles. Silicone's excellent waterproofing ability is attributed to its low surface energy, the most common waterproofing agent in this category, which the hydroxyl silicone oil, dimethyl silicone oil, and hydrogen silicone oil. The three main chain structures are as follows:
Textiles treated with silicone waterproofing agent, can achieve significant waterproofing effect, the main reason is: the polymer film on the fiber surface, the molecular side chain contains functional groups arranged in the direction of the air, and the active groups are easy to react cross-linking and easy to bonding with the fiber, and ultimately a layer of smooth film covering the surface of the fiber, and play a role in blocking the water, oil droplets and other infiltration of the role of the textile. Silicone waterproofing agent in the textile surface film schematic diagram below.
4. Why should silicone waterproofing agent be used in textiles?
Silicone waterproofing agents used in various types of textile finishing have been a welcome achievement, due to the silicone waterproofing agent raw materials, low price, breathable and soft effect, and other comprehensive performance is excellent, and has a high cost-effectiveness, prompting the silicone products in the textile industry has be widely used. It is worth noting that silicone water repellents only need a small amount to make the textile have obvious hydrophobicity, a soft effect is good, and can enhance the textile's shape retention, and so on. If the dosage is too much, it generates a double-layer silicone membrane on the polar surface, hydrophobicity decreases, and water washing resistance decreases, which may be due to the hydrolysis of siloxane and the swelling effect of fibers in water, leading to the rupture of the silicone membrane.
In addition, the application effect of some unmodified single components still reveals different degrees of disadvantage. Hydrogen-containing silicone oil because of its high activity of the Si-H bond, with the help of a catalyst, can be grafted with different functional groups to modify it, on the one hand, to change its molecular structure, on the one hand, access to the functional groups in different industries in the application of the effect of unique, combined with the two, and continue to work on the development of new types of multi-stylized, multi-functional silicone products, is a potential unlimited, far-reaching and extremely valuable direction of research. It is a direction with unlimited potential, far-reaching significance, and great research value.
Fluorine polymers are difficult to degrade, extremely hazardous, and the feel and softness of textiles are significantly worse after treatment. On the other hand, compared with fluorine-based products, silicone-based water repellents are less oleophobic. For fluorine, silicon polymer disadvantages, in order to make up for their shortcomings, to take the fluorine, silicon jointly introduced into the polymer, and then set the two sides of the excellent characteristics of one, complement each other, play their characteristics. Preparation of fluorosilicone finishing agent with excellent hydrophobicity, oleophobicity, resistance to high and low temperatures, anti-fouling, and other comprehensive application characteristics. Its R&D progress has drawn the attention of the general public, with very high application potential.
