Abstract

The invention relates to the technical field of thin films and in particular to a cement packaging thin film. The cement packaging thin film comprises the following components in parts by mass: 30-50parts of modified polypropylene, 10-20 parts of polyethylene, 18-24 parts of polyester fibers, 12-15 parts of ABS resin, 2-8 parts of asbestos powder, 2-5 parts of carbon fibers, 12-15 parts of glassfibers, 2-4 parts of 2-hydroxypropyl-Beta-cyclodextrin, 2.5-4.5 parts of acrylic acid hydroxypropyl ester, 4.2-5 parts of metacrylic acid ester, 0.3-0.5 part of titanium dioxide, 2.1-3.8 parts of calcium carbonate powder, 7-9 parts of kieselguhr, 3-4 parts of a coupling agent, and 4-8 parts of a fire retardant. The cement packaging thin film is capable of, through adding the modified polypropylene, increasing toughness after modifying polypropylene by a specific method, enabling a branched chain to become active, and cross-linking with other raw materials well, thereby increasing strength of the thin film, and has excellent performance, good stability, good strength, slow aging speed, high wear resistance, good using effect, and wide application range.

Description

technical field [0001] The invention relates to the technical field of films, in particular to a cement packaging film. Background technique [0002] For a long time, cement, as an important cementitious material, has been widely used in civil engineering, water conservancy, national defense and other projects. Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in air or better hardened in water, and can firmly bind sand, stone and other materials together. [0003] Cement bags play a vital role in carrying the weight of cement. Now cement companies use gas and mechanical conveying cement filling methods when filling cement. The exhaust problem during cement filling is not solved well, which reduces the firmness of the packaging bag. The problem of moisture resistance cannot be solved. Contents of the invention [0004] The purpose of the present invention is to provide a packaging film with high stre...
