The invention discloses a method for producing an epoxy crosslinking modified paper humidity intensifier. The alkaline cured humidity intensifier polyamide polyamine epoxy chloropropane resin is the mainstream product at present, but the PAE which is not cross-linked and modified is poor in the crosslinking degree and molecular weight and has poor retaining performance, and the humidity-intensifying effect of the paper can not reach the production requirement, and can result in the increase of the adsorptive organic halide in the wastewater. The invention adopts the dibasic acid and polybasic amine as the raw material to produce the intermediate of polyamide polyamine; a certain amount of polyamide polyamine intermediate, epoxy and epoxy chloropropane react under certain temperature until the product reaches a certain viscosity, then acid is added to terminate the reaction and obtain the epoxy crosslinking modified paper humidity intensifier. The method can reduce the consumption of the epoxy chloropropane and decrease the content of organochlorine in the waste; the retaining rate of the product is greatly improved; the product provided by the invention can not only improve the wet strength of the paper but also can increase the physical properties of the paper, such as the folding strength, tensile strength and dry strength and the like.

The invention discloses a preparation method of a paper wet strengthening agent that is modified by organic silicon, which comprises the following steps: firstly combines the raw materials of dibasic acid and polyhydric amine into a polyamine intermediate compound of daiamid.
