Abstract
The invention relates to a preparation method of polyfunctional UV (Ultraviolet)-cured organic silicon resin. The preparation method comprises the steps: enabling aliphatic polyisocyanate containing three or more than three isocyanate groups to react with a silane coupling agent for 1.5 hours while heating and agitating under the temperature of 45 DEG C and in the presence of a catalyst to obtain a product (A); heating to reach the temperature of 50 DEG C; feeding a monomer which contains -OH and -C=C groups and has molecular weight less than or equal to 1000 to the reaction system while heating and agitating in the presence of the catalyst, so as to continuously react with the product (A) to obtain a product (B) which is the polyfunctional UV-cured organic silicon resin. With the adoption of the preparation method, the disadvantage of high temperature curing of the organic silicon resin can be solved; a plurality of double-bond structures are formed at the chain end of the prepared polymer, and therefore, the prepared resin can be subjected to UV curing under the room temperature, and meanwhile, the same performances can be achieved, such as heat resistance, weather resistance and mechanical property.
Description
Technical field
The present invention relates to a kind of preparation method of polyfunctionality UV cured silicone resin, belong to photo-cured coating field.
Background introduction
UV is coating material solidified is a kind of new green environment protection type coating, has and pollutes the advantages such as little, energy consumption is low, set time is short.UV is coating material solidified primarily of prepolymer, reactive monomer, light trigger and auxiliary agent composition, and wherein prepolymer constitutes the skeleton of cured film cross-linked structure, and it is the main determining factor of product physical and chemical performance.Tradition silicone resin generally all needs hot setting (150 ~ 200 DEG C), and when set time is long, large-area construction is inconvenient, temperature poor to the poor adhesive force of bottom, organic solvent resistance is higher, the physical strength of paint film is bad.The modification UV cured silicone resin adopting the monomeric aliphatic isocyanate such as hexamethylene diisocyanate trimer (HDT), pentaerythritol triacrylate (PETA), Hydroxyethyl acrylate (HEMA), Acrylic Acid Monomer obtained is compared with traditional silicone resin, there is higher sticking power, wear resistance, oil-proofness and chemical-resistant, and chain end has a large amount of double bond structure, can at room temperature solidify by UV, heat-resisting, weather resistance is good, has great potential in photo-cured coating field.
Summary of the invention
The present invention relates to a kind of preparation method of polyfunctionality UV cured silicone resin, its object is to provide a kind of utilize isocyanic ester and Acrylic Acid Monomer modified synthesis there is moderate molecular weight and the silicone resin of the resistance toheat of excellence.In this polymkeric substance, the polymkeric substance end of the chain has a large amount of double bond structure, and this makes prepared resin at room temperature can carry out UV solidification, avoids the shortcoming that traditional silicone resin needs hot setting, and identical performance can be reached equally, as thermotolerance, weathering resistance, mechanical property etc.
