Abstract
The invention discloses a preparation method of an adhesive based on a mercapto Michael addition reaction, which comprises the following steps: oxidation and purification of BPx: dissolving bisphenol compounds in an organic solvent, adding an oxidant, and stirring at room temperature to form a red solid; cooling and then carrying out vacuum filtration; re-dissolving the filter residue, and repeatedly performing suction filtration to remove unreacted reactants to obtain a red solid product; dissolving the red solid substance in an organic solvent, performing vacuum filtration, and performing rotary evaporation to remove the solvent in the filtrate to obtain a purified red solid product, wherein the purified red solid product is BQx; preparation of the adhesive based on the mercaptomichael addition reaction: BQx is dissolved in organic solvent, the solution of the biquinones compound is prepared by magnetic stirring, and the multi-sulfhydryl compound is added to react to obtain light yellow solution; purification of the adhesive based on the mercaptomichael addition reaction: and dripping a precipitator into the light yellow solution under the stirring state, and centrifuging at a high speed to separate a supernatant and a precipitate to obtain a yellow viscous compound serving as a final adhesive. The adhesive prepared by the preparation method has high adhesive strength and good underwater adhesion.
Description
Technical Field
The invention relates to the field of high polymer materials, belongs to the fields of chemical engineering, biomedical materials and marine industry, and particularly relates to a preparation method of an adhesive based on a mercapto Michael addition reaction.
Background
Polymer adhesive materials are widely used in various fields such as biomedicine, underwater equipment and marine industry. Polymer adhesives are now being put into commercial production. However, most adhesives currently only work on the surface of dry solids, forming a permanent or reversible bond with the dry surface. However, in many applications, adhesives that can bond to wet surfaces or surfaces submerged in aqueous media are needed, such as medical implantable devices, wound dressings, underwater sensors, and the like. And adhesives that have been put into commercial use today also suffer from the problem that the strength of adhesion does not achieve the desired target. Therefore, it is a breakthrough in this field to develop a new adhesive having high adhesive strength and suitable for use in underwater environments.
Most of the underwater adhesives developed today draw inspiration from the nature. For example, inspired by marine mussel organisms, permanent underwater adhesion is achieved using l-3, 4-Dihydroxyphenylalanine (DOPA), where the key contributing structure is the catechol group. In the past decade, inspired by this, significant progress has been made in the design and manufacture of new underwater adhesives. For example, chinese patent publication No. CN107916078A discloses a method for preparing a starch-based mussel-like adhesive based on a chemical-biological coupling method, which utilizes simple chemical reaction and laccase catalysis to generate reactive active quinones and other structures to prepare a novel functional material with starch as a macromolecular skeleton and dopa-containing side groups, and achieves the purpose of improving the starch bonding strength through biomimetic bonding. For example, chinese patent publication No. CN107625991A discloses a method for preparing a mussel-like functionalized fracture adhesive, which uses a catechol-containing structural polymer, hydroxyapatite and chitosan as raw materials, wherein the raw materials for preparing the catechol-containing structural polymer are polyethylene glycol, acrylic acid chloride and a catechol-containing structural compound, and the catechol-containing structural compound is dopamine hydrochloride. However, the research on the current adhesive is more dependent on the existing catechol group-containing compound, and the large-scale development and application of the catechol-containing adhesive cannot be realized, so that the development of a large amount of catechol-containing adhesive which can be chemically synthesized is the current research hotspot.
Bisphenols are compounds in which two hydroxyphenyl groups are bonded together by one or more carbon atoms, optionally a sulfur atom and an oxygen atom. Bisphenols are of great interest because of their endocrine disrupting properties. The bisphenol compound is introduced into a high molecular chain by chemical reaction and is possibly expanded into a substance with biological friendliness, the biological safety problem of the bisphenol compound monomer is solved, and the catechol group is obtained by the oxidation-reduction reaction of the bisphenol compound, so that the high adhesion of the adhesive material is facilitated.
The mercapto group is a negative monovalent functional group formed by connecting a sulfur atom and a hydrogen atom, the chemical formula is-SH, and the multi-mercapto compound refers to a compound containing two or more mercapto groups. The mercapto Michael addition reaction is a common method for growing carbon chains and is widely applied to polymer reactions. The mechanism is a conjugate addition reaction of a compound containing an electrophilic conjugate system as an electron acceptor with a nucleophilic mercapto group, i.e., an electron donor. The reaction system is efficient and rapid, and can generate a polymer chain segment with a certain connecting group.
