Based on the alkylalkoxy silane as basic raw material, the silicone water-proof agents with good properties were prepared through chemical modification and emulsification.
Liquid silicon water repellent agent is used in this experiment.
As a new type of water repellent agent, silicon water repellent agent can form a barrier on the cover of concrete, for the aim to reduce the penetration of chloride ion.
Experience acquired over more than thirty years shows that silicone water repellents are a good solution, especially when treating building materials that must retain their natural appearance.
Waterproof bonding layer, as a very thin layer on the structural design of porous asphalt pavement, is used to prevent the rainwater from the bottom of the top asphalt layer permeating through conjoint layer as well as to provide good adhesion between layers.
The company's main products are silicone waterproofing agents, paper additives, stone conservation agent, cleaning agent cleaning, polymer absorbent, soil moisture, colorful crystal soil, as well as some household and industrial chemicals.
Through the modified effect contrast between polymer latex and redispersible polymer powder which mixed to cement slurry within 5%, the influence of adding organic silicon waterproof solvent to modified cement slurry, and seawater resistant property when coating the surface of timbers, especially for the scene observation of this material's cohering property, resistance to abrasion, impact resistance and cracking when it was soaked in seawater for 28 days.
Organosilicon high-boiling components was by-product from direct synthesis of methylchlorosilanes, The routes for production of monosilane, silicone oil, organosilicon water-proof agent, defoaming reagent, ceramics, organosilicon resin from the high-boiling components and their technical features were outlined, and some suggestions on development direction of catalysis cracking were put forward.
Modified organosilicon waterproofing agent was prepared by way of emulsion polymerization with acrylate and methyl alcoholate silicate as raw materials, OP-10 and SDBS as emulsifiers.
The silicone molecules in the coatings can be adhered with the hydroxy group on the surface of substrate to form a network hydrophobic silicone film with excellent water proofness and durability.
The aerogel has good hydrophobic property after surface hydrophobic treatment with organo-silicone waterproofing agent.
Taking Shanghai Middle Ring Road project as example, the principle and effect of D-125 as a waterproof agent are described.
