The invention belongs to the technical field of
papermaking, and particularly relates to a preparation method of a nylon wear-resistant
papermaking dry net, which comprises the following specific steps: S1, mixing dried nylon chips with
graphene powder according to a certain proportion, adding other auxiliaries (
silane coupling agent and
active agent SDBS) in parts by weight, 95-99.5 parts of
polyester chips and 0.5-5 parts of talcum
powder in the mixing process, and uniformly mixing to obtain a nylon wear-resistant
papermaking dry net; 5-10 parts by weight of a
silane coupling agent and 0-5 parts by weight of an
active agent SDBS; s2, extruding through a screw extruder, molding through a cooling device, and carrying out stretching,
heat setting and oiling treatment to prepare monofilaments; according to the step, a monofilament cooling structure is formed by arranging a cooling platform, a
water cooling box, a water distribution
pipe, a water inlet header
pipe and a water drainage
pipe, the function of keeping the temperature consistent when monofilaments are cooled is achieved, the problem that the water temperatures of all parts are inconsistent when the monofilaments are cooled is solved, and the material
machining quality is improved; and the condition of inconsistent monofilament uniformity caused by inconsistent temperature during monofilament cooling is reduced.
