Waterproof corrugated paper, manufacturing method thereof, manufacturing apparatus thereof, and usage thereof

A manufacturing method of a waterproof corrugated paper comprises:

• providing a stone paper medium;
• utilizing a corrugated synchronized roller to make the stone paper medium wave-shaped and to have a first fluting surface;
• providing a stone glue, wherein the stone glue comprises a linear polyolefin plastic material and an inorganic material, and the linear polyolefin plastic material accounts for 30 wt %-70 wt % of a weight of the stone glue;
• the inorganic material accounts for 30 wt %-70 wt % of the weight of the stone glue;
• utilizing a glue roll set to apply the stone glue to a plurality of wave crests of the first fluting surface of the stone paper medium;
• and
• attaching a stone liner paper to the plurality of wave crests of the first fluting surface of the stone paper medium to form the waterproof corrugated paper, wherein a production speed of the waterproof corrugated paper is over 150 m/min;
• wherein the stone paper medium in a corrugated shape has a thickness and a wave height;
• the thickness is in a range of 0.10 mm-0.25 mm, the wave height is in a range of 0.6 mm-6.0 mm;
• wherein the glue roll set comprises a plurality of rollers and a stone glue supply unit, and the stone glue supply unit is adapted to provide the stone glue from a site above the plurality of rollers;
• and wherein at least one of the plurality of rollers is heated;
• wherein the plurality of rollers comprises a first roller, a second roller, and a third roller, a circumference of each of the plurality of rollers is flat;
• the first roller is adapted to apply the stone glue to the plurality of wave crests of the first fluting surface of the stone paper medium;
• the second roller is located between the first roller and the third roller;
• the stone paper medium passes on a side of the first roller which is opposite to the second roller;
• the stone paper medium is provided by a stone paper medium supply unit, and the stone paper medium supply unit is located above the glue roll set.
