Abstract

The invention provides a composite film cement packaging bag, which relates to the field of cement bags; it includes a plastic woven bag and a film, and the plastic woven bag is composed of the following raw materials in parts by weight: 50-70 parts of modified polypropylene, 30-30 parts of polyethylene 40 parts, 15-25 parts of polyester fiber, 10-18 parts of ABS resin, 5-10 parts of asbestos powder, 8-15 parts of urea-formaldehyde melamine resin, 12-16 parts of aluminum oxide, 13-17 parts of dicumyl peroxide , 6-10 parts of recycled material, 2-4 parts of color masterbatch, 3-5 parts of whitening agent; the film is composed of the following raw materials in parts by weight: polyethylene 40-55 parts, polypropylene 10-15 parts, carbon fiber 2- 5 parts, 15-20 parts of fatty acid polyoxyethylene resin, and 10-13 parts of furfural resin; the cement packaging bag prepared by the invention has high strength, good firmness, and improved moisture-proof performance.

Description

technical field [0001] The invention relates to the field of cement bags, in particular to a composite-film cement packaging bag. 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] (1) Solved technical problems [0005] Aiming at the deficiencies of th...
