Abstract

The invention belongs to the technical field of chemical synthesis and provides a Poly(diphenylethylene-2-phenylacrylic acid)-polyester resin and a preparation method and application thereof. The preparation method comprises the following steps: (1) polyol, polyacid, anhydride and dicyclohexylcarbodiimide are dissolved in N,N-dimethylformamid to form a reactant A; (2) a reactant B is obtained by the reaction of the reactant A and 2-phenylacrylic acid under the action of Ziegler catalyst; (3) diphenylethylene is mixed with an initiator and a dispersing agent, and heating and stirring are carried out, so that a reactant C is obtained by reaction; and (4) the reactants C and B are mixed, heating is carried out under stirring, then a crosslinker and an initiator are added for continuous reaction to obtain the poly(diphenylethylene-2-phenylacrylic acid)-polyester resin. The poly(diphenylethylene-2-phenylacrylic acid)-polyester resin can significantly improve the adhesion and high temperature resistance of ink when applied to PVC floor ink.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a poly(stilbene-2-phenylacrylic acid)-polyester resin and its preparation method and application. Background technique [0002] The development of modern life puts forward different requirements on the performance of polymer resins. Under the guidance of the principle of chemical reaction, with the further development of modern technology, people adjust the degree of polymerization of polymers, the reactants used in polymerization reactions, and the A variety of polymers can be produced by the amount ratio of the reactants and the like. The preparation of new polymers has brought people's living standards to a higher level. [0003] Plastic floor (PVC floor), the main component is polyvinyl chloride material, PVC floor can be made into two types, one is homogeneous and transparent, that is, the pattern material from bottom to surface is the same. There is...
