Photo-curing monomer with ortho-phenolic hydroxyl structure, preparation method and bond thereof

Abstract

The invention discloses a photo-curing monomer with ortho-phenolic hydroxyl strucutre, a preparation method and bond thereof. In the formula I monomer, the compound which has crylic acid at two ends or crylic acid double bond at one end and methylacrylic acid double bond at the other end is added to the amidogen of dopamine and derivant thereof through a Michael addition method to form corresponding secondary amine or tertiary amine. In the formula II monomer, the double bond is introduced by (methyl) acrylic anhydride, (methyl) crylic acid and (methyl) acryloyl chloride. The photopolymerization bond comprises the following components by weight percent: 20 to 99.9 percent of the compound with the ortho-phenolic hydroxyl structure, 0 to 70 percent of activated thinner and / or solvent, 0.1 to 10 percent of evocating agent and 0 to 60 percent of natural macromolecule or modified outcome thereof. The bond can be bonded in dry state and wet state, is a quick and long lasting bond, realizes the organic bond of biological bond and photopolymerization, has the advantages of low manufacture cost, simple and convenient operation and high productivity and has extensive application foreground in the biological bond field.

Description

technical field The invention relates to a photocurable adhesive monomer, its preparation and its application as an adhesive, belonging to the field of adhesives. Background technique The o-phenolic hydroxyl group of dopamine or its derivatives can form a complex with metal ions in the body. If the o-phenolic hydroxyl group of dopamine or its derivatives is oxidized, or encounters oxidative substances such as tyrosinase in the body, o-quinone is formed The structure of the protein is a substance that can form a covalent cross-linked substance with the protein in the body. This property endows the compound with ortho-phenolic hydroxyl structure with good adhesion in both dry and wet environments. Photopolymerization (also known as photocuring) technology is a new green technology that came out in the 1960s. Photocuring technology: high efficiency, wide adaptability, economy, energy saving and environmental friendliness. These characteristics endow photopolymerization techn...
