Preparation method and application of porous surface grafted adsorptive deodorant

The invention provides a preparation method and application of a porous surface grafted adsorptive deodorant. The main structure is composed of a photocurable formula, a porous material is formed through pores appearing through polymerization, and then surface grafting is carried out through terminal carboxyl and a polyamino compound. Different porous material effects can be achieved by controlling the composition of the photocurable formula, and small-molecular substances such as formaldehyde and vinyl chloride in plastic can be well absorbed by grafting a large number of loaded amino groups. Meanwhile, the porous surface grafted adsorptive deodorant can also be used for replacing a stabilizer in a polymeric material, and the stability of the plastic is enhanced by absorbing free micromolecules in a high-molecular polymer system. 本发明提供了一种多孔表面接枝吸附性除味剂的制备方法及其应用。本发明的主结构由可光固化配方组成，通过聚合出现的孔隙来形成多孔材料，然后通过末端羧基和多氨基化合物做表面接枝。通过控制可光固化配方的组成能够实现不同的多孔材料效果，通过接枝负载的大量氨基，能够非常好的吸收塑料中小分子的物质，如甲醛、氯乙烯等。同时所述多孔表面接枝吸附性除味剂还可以代替聚合材料中的稳定剂
