Abstract

The invention discloses a pressing-bar environment-friendly mulching film capable of heat preservation and water retention, wherein composition proportions of polypropylene, natural fibers, calcium carbonate and an adhesion agent are 30-70%, 10-50%, 10-20% and 5-10%, respectively. The pressing-bar environment-friendly mulching film is shaped through an extrusion technology; the pressing-bar environment-friendly mulching film is equipped with parallel pressing bars; composition proportions of materials of the mulching film, preparation technologies of the mulching film, the structure of the mulching film and so forth are combined organically and rationally, so the pressing-bar environment-friendly mulching film is obtained; and thus various problems appearing in use of traditional mulching films can be solved, and the film has a lot of technological advantages. For example, the film is degradable and constituents can be adjusted according to cultivation demands. In this way, degrading duration of the pressing-bar environment-friendly mulching film is fitted with crop culture duration which requires duration of mulching film covering.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a layered environmental-friendly mulching film for heat preservation and water retention. Background technique [0002] In the cultivation of crops, due to the needs of growth, it is often necessary to use plastic film for heat preservation and water retention. There are many crops cultivated with plastic film, such as peanuts, tobacco, tomatoes, strawberries, etc. Although traditional plastic film can play a role in the use of plastic film It has the effect of heat preservation and water retention, but it is also inconvenient to use. For example, the plastic film is generally made of polyethylene, which is not easy to decompose and is easy to cause environmental pollution. Especially when the plastic film is damaged during recycling, farmers basically use incineration to dispose of it. [0003] In traditional mulch cultivation, mulching is required. When the crops grow to a cert...
