Abstract

The invention relates to a double-reinforced mulching film and a manufacturing method thereof, and aims to solve the technical problem of incapability of recycling and reducing ultraviolet absorption in the conventional mulching film technology. The manufacturing method comprises the following steps of: pretreating linear low-density polyethylene, low-density polyethylene, metallocene and vinyl acetate, namely stirring the components, and packaging 30 to 40 weight percent of linear low-density polyethylene, 30 to 40 weight percent of low-density polyethylene, 10 to 20 weight percent of metallocene and 10 to 15 weight percent of vinyl acetate which are pretreated and 1 to 5 weight percent of aid into separated bags. A double-reinforced mulching film comprises three layers, namely an outer layer, a middle layer and an inner layer; and the double-reinforced mulching film is manufactured by utilizing the components which are packaged into separated bags, wherein the outer layer, the middle layer and the inner layer are subjected to film blowing respectively by utilizing a constant-temperature coextrusion film blowing machine, are cooled and rolled by a melting combination process and are packaged to obtain the double-reinforced mulching film. The double-reinforced mulching film is tasteless and non-toxic, the reinforced part and the laminated part have a high light-reflecting function, the service life of the mulching film can be prolonged by reducing ultraviolet rays, and the double-reinforced mulching film is recycled conveniently.

Description

technical field [0001] The invention relates to a mulch product and a manufacturing method thereof, in particular to a double fascia and a manufacturing method thereof. Background technique [0002] Due to the needs of modern agricultural planting, most areas use the dripper mode for watering. Since the drip irrigation belt is black, after the white mulch is covered, the black part is easy to age and crack due to sunlight, causing water to evaporate, and the amount of water used increases at the same time. , the heat preservation and moisturizing function of the product is reduced. Ordinary film cultivation crops do not have the functions of fixed distance, labor reduction, and ultraviolet radiation reduction. They cannot suppress weeds. . Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that the existing common mulch technology cannot achieve recycling and reduce ultraviolet absorption, and to provide double fa...
