Abstract: The present invention relates to a method for manufacturing a paper straw, the method comprising: a paper roll transmission step, a paper strip heating step, a bonding and shaping step and a cutting step. Wherein, a plurality of raw paper rolls face a connection position jointly to transmit a raw paper strip, the raw paper strip includes a paper material and a dry hot-melt adhesive. The dry hot-melt adhesive of the raw paper rolls is heated for changing into flow hot-melt adhesive. Then the raw paper rolls is transmitted to the connection position for rolling jointly, and the flow hot-melt adhesives are bounded on another raw paper strip to form a pipe. Finally, the pipe is cut to form at least one paper straw after the pipe exceeds a setting length.

Abstract: The present invention relates to a paper material for producing a paper straw mainly, the paper material includes: a paper and a hot-melt adhesive material; wherein, the hot-melt adhesive material is provided on at least one surface of the paper, including an acrylic acid copolymer 40%˜45% w/w, an ammonia water less than 0.1% w/w or equal to 0.1% w/w and a water 55%˜60%. w/w The hot-melt adhesive material is presented as a dry hot-melt adhesive without viscosity and being transformed to a flow hot-melt adhesive with viscosity while being heated from 80° C.˜200° C.

Abstract: A waterproof coating process machine and its negative pressure coating and atomized coating methods are disclosed. The machine includes a coating process tank disposed at a top end, a drying chamber and a control panel. A discharge port connected with a discharge pipe on an outer side is disposed at a bottom of the coating process tank; and at least one negative pressure suction port connected with a suction pipe of a suction pump is disposed on a back side. An opening of the drying chamber in combination with a movable door is disposed at a front side of a lower section of the machine. An infrared outlet, an infrared spiral wave outlet and a circulation fan are disposed inside the drying chamber. The control panel is disposed on the front side of the machine between the coating process tank and the drying chamber.
