Problems solved by technology

At present, the curing methods of silicone-coated polymers mainly include condensation curing and thermal curing. These two traditional curing methods have more or less defects, such as a long period of condensation curing, about 2-3 days, The curing temperature required for thermal curing is higher, above 100°C, which makes the silicone polymer coating cannot be applied to some specific fields, such as substrates that require short operating cycles or are sensitive to temperature

Abstract

The invention discloses a fluorosilicone polymer capable of being subjected to UV light and heat curing, a preparation method thereof and a coating. The fluorosilicone polymer capable of being subjected to UV light and heat curing is formed by polymerizing the following components in parts by mass: 10-80 parts of fluorine-containing cyclic siloxane; 10-80 parts of cyclic siloxane containing a vinyl group; 0-80 parts of a dimethyl cyclosiloxane mixture; 0.1-10 parts of 1, 3-dihydroxyalkyl-1, 1, 3, 3-tetramethyldisiloxane; 1-1000 ppm of a base catalyst; 1-1000 ppm of an acid neutralizer; 0.1-10 parts of diisocyanate; 1-1000 ppm of an organic tin catalyst; and 0.1-10 parts of hydroxyalkyl methacrylate or hydroxyalkyl acrylate. The fluorosilicone polymer has good solvent resistance and heat resistance, and is suitable for two curing modes of thermocuring and UV photocuring, and when UV photocuring is utilized, the fluorosilicone polymer has the advantages of short curing period and high efficiency, so that the application field of the fluorosilicone polymer, such as the field of electronic protective coatings, is greatly expanded.

Description

technical field [0001] The invention relates to the field of preparation of organosilicon polymer materials, in particular to a fluorosilicon polymer curable by UV light and heat, a preparation method and a coating thereof. Background technique [0002] At present, there are many kinds of coatings used in the market, among which polysiloxane-based silicone coatings occupy an extremely important position because of their many application products and wide application fields. At present, the curing methods of silicone-coated polymers mainly include condensation curing and thermal curing. These two traditional curing methods have more or less defects, such as a long period of condensation curing, about 2-3 days, The curing temperature required for thermal curing is relatively high, above 100°C, so that silicone polymer coatings cannot be applied to some specific fields, such as substrates that require short operating cycles or are sensitive to temperature.
