The invention relates to an environmentally-friendly recycled paper and a preparation method thereof, which belong to the technical field of paper making. The method uses
waste paper as a raw materialto synthesize two hydrophilic group surfactants, the
surface tension is reduced, and steps of penetration, emulsification and dispersion are carried out on an ink, thereby removing, the whiteness ofthe
waste paper is improved, and the recycled paper can be re-printed and reused; an active
methylene hyperbranched
waste paper formaldehyde-removal additive is prepared by taking
ethyl acetoacetate and hydroxyl terminated
hyperbranched polyester as raw materials, so that the
formaldehyde can be captured and removed; dicyandiamide and hexanediamine dihydrochloride are taken as raw materials,
ciprofloxacin is added for clathration as an
antibacterial agent, the
irritation is reduced, the utilization is increased and the action time is prolonged, the
antibacterial property of recycled paper is increased, and
mildew can be prevented; a silica
sol is used as a
raw material, and by compounding with
calcium carbonate and
bentonite, the mechanical properties of recycled paper and the
tear resistance can be improved. The environmentally-friendly recycled paper solves the problems of high
formaldehyde content and poor
water resistance of waste paper at present.
