Abstract

The invention relates to a polypropylene woven bag, which is composed of, by mass, 100 parts of PP(polypropylene); 15-20 parts of LDPE; 0.05-0.2 part of an antioxidant 1010; 1-5 parts of white oil; 1-5 parts of zinc white; 1-5 parts of PP-g-MAH; 0.1-0.5 part of an antioxidant DLTP; 0.2-1 part of zinc stearate; 5-10 parts of titanium dioxide; 0.05-0.25 part of DCP; 0.025-0.05 part of UV-327; 0.5-1 part of a coupling agent; and 10-20 parts of calcium carbonate. The product has tensile strength of 5-10MPa, elongation of 25-30%, fineness of 180-200, and has no change after 24h of soaking in strong alkali. The product is acid and alkali resistant and wear resistant, can be widely produced and used for replacing existing materials continuously.

Description

technical field [0001] The application belongs to the field of plastic materials, in particular to a polypropylene woven bag. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials. Australian coins are also made from polypropylene. It has the advantages of high strength, high hardness, wear resistance, bending fatigue resistance, high heat resistance, excellent moisture resistance and chemical resistance, easy processing and molding, and low price. At the same time, it has the disadvantages of poor low temperature toughness and aging resistance. [0003] Polypropylene is a general-purpose plastic resin with a wide source and low price, and has a very wide range of uses. However, due to its high brittleness, high crystallinity, and low mole...
