Because of its excellent waterproof properties, silicone resin has been widely used in construction, electronics and automobiles.This article will discuss the waterproof properties, preparation methods and main application areas of silicone resin.
Waterproof properties of silicone resin
Hydrophobicity: Silicone resin has natural hydrophobicity, which can effectively prevent moisture penetration.Its surface energy is low and the water contact angle is large, making it difficult for water droplets to spread on its surface.
Chemical stability: Silicone resin has excellent chemical resistance to water, acids, alkalis and salts, and can maintain stable performance for a long time in humid and corrosive environments.
Weather resistance: Silicone resin has excellent resistance to ultraviolet rays, ozone and extreme temperatures, and is suitable for long-term use in outdoor and harsh environments.
Flexibility: Silicone resin has certain flexibility, can maintain good waterproof performance under mechanical stress, and is suitable for waterproof treatment of complex shapes and structures.
Preparation method of silicone resin waterproof material
The preparation of silicone waterproof materials usually goes through the following steps：
Basic polymer synthesis: Through the polymerization reaction of organosilicate monomers, a silicone resin prepoler with an active end group is prepared.
Crosslinking and curing: By heating or adding a catalyst, the silicone resin prepoler is crosslinked and cured to form a three-dimensional network structure.
Additive mixing: Add fillers, plasticizers and other additives as needed to adjust the mechanical properties and construction properties of silicone resins.
Application areas of silicone resin waterproof materials
Construction field: In building waterproof coatings, sealants and waterproof membranes, silicone resin has become a high-performance building material because of its excellent water resistance and weather resistance.
Electronics field: In electronic packaging and circuit board coatings, silicone resin waterproof materials can effectively protect electronic components from humid environments.
Automotive field: In the sealing of automobile bodies, car windows and lights, silicone resin waterproof materials are widely used in automobile manufacturing because of their high temperature resistance and flexibility.
Aerospace: In the waterproof sealing and coating of aerospace spacecraft, silicone resin waterproof materials have become key materials because of their high temperature resistance and weather resistance.
With its excellent water resistance, chemical stability and weather resistance, silicone resin has shown a wide range of application prospects in the fields of construction, electronics, automobiles and aerospace.With the progress of materials science, the performance of silicone resin waterproof materials will be further improved, and the application fields will be more diversified.
