Description

Technical field: [0001] The invention relates to the technical field of chemical materials, in particular to a nano-titanium oxide modified organic silicon adhesive. Background technique: [0002] Silicone adhesives have excellent resistance to cold and heat changes, stress changes, etc., high and low temperature resistance, long-term elasticity and stability at -60 to 200 ° C, and excellent insulation, moisture resistance, shock resistance, corona resistance, and Leakage and chemical resistance properties, and widely used in various industrial sectors. In recent years, with the continuous emergence of new varieties of silicone adhesives, their consumer demand is increasing. However, silicone adhesives have poor weather resistance and poor self-cleaning properties. [0003] As a new type of functional material that has attracted much attention in recent years, nano-titanium oxide can be used in silicone adhesives, which can effectively improve the weather resistance and se...
