Environment-friendly recycled paper preparation method

The invention relates to an environment-friendly recycled paper preparation method which comprises the following steps: S1, pretreatment; S2, purification; S3, pulping: feeding into a pulper for crushing, adding water, mixing and crushing into paper pulp; S4, screening; S5, quantifying the paper; S6, preparing a self-made reinforcing agent: selecting acrylamide AM, methacryloyloxyethyl trimethyl ammonium chloride DMC and a 2-acrylamide-2-methyl-1-propanesulfonic acid AMPS monomer for compounding, and adding an emulsifying agent to obtain the reinforcing agent; and S7, cooling: adding the reinforcing agent within 5 minutes before the paper sheet is formed, uniformly stirring, then carrying out drying treatment in a paper sheet forming device, feeding the paper sheet into a cooling system for cooling, and carrying out cooling treatment on the paper sheet for 24 hours. The preparation method has the beneficial effects that the strength and the tensile coefficient of the obtained paper areobviously improved, and
