The invention discloses a waterproof
corrosion-resistant antiaging high-flexibility rich mineral paper and a preparation method thereof. The rich mineral paper is composed of the following raw materials in parts by weight: 15-20 parts of
synthetic resin, 1-5 parts of EVA / EAA (
ethylene-
vinyl acetate /
ethylene-
acrylic acid)
copolymer, 55-60 parts of inorganic
powder, 5-10 parts of shielding agent, 1-4 parts of
preservative, 0.1-1 part of antiaging agent and 1-10 parts of assistant. The preparation method comprises the following steps: weighing raw materials according to the formula proportion, uniformly mixing, sending into an 80-120-DEG C mixer, mixing for 5-15 minutes to activate the materials, mixing by a 100-240-DEG C Banbury mixer for 5-10 minutes, pressing the obtained material into a single screw / double screw extruder through a bi-
wrist /
bipyramid feeder, carrying out
extrusion forming at 130-190 DEG C, cooling, granulating, introducing the master batch into a
drying machine,
drying until the
water content is less than 0.3%, extruding by a 190-230-DEG C DEG C,
calendering by a 40-70-DEG C calender, carrying out cooling to form, and trimming to obtain the rich mineral paper finished product. The rich mineral paper has the advantages of
water resistance,
corrosion resistance,
aging resistance, long use period, high / low
temperature resistance, simple production technique and very high popularization value.
