Abstract

The invention belongs to the technical field of cover film application, and particularly discloses a thermal insulation and heat preservation composite mulching film. The composite mulching film is composed of a first black PE film layer, a second black PE film layer and a composite layer arranged between the first black PE film layer and the second black PE film layer. The thermal insulation and heat preservation composite mulching film has the advantages that a formed multiple-layer composite structure has characteristics of high heat preservation, moisture protection, oxidation resistance, shading performance, corrosion resistance and the like, and has high anti-tensile strength at the same time, and the appearance is flat and attractive; a thermal insulation layer and ultraviolet-proof layer structure can effectively insulate external heat, avoid the influence on covered stuffs by high temperature, meanwhile the heat preservation performance can be improved, the service life of the overall film layer is prolonged, the cost is lowered, the overall structural surface is flat, and the package is practical and attractive; the thermal insulation and heat preservation composite mulching film is reasonable in design and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of application of covering films, and in particular relates to a heat-insulating and heat-preserving composite mulching film. The multi-layer composite structure formed by the film has the characteristics of heat preservation, moisture resistance, oxidation resistance, light-shielding performance and corrosion resistance. Background technique [0002] Mulch film is the ground covering film, usually transparent or black PE film, and there are also green and silver films, which are used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc. , the function of promoting plant growth. [0003] In the past two decades, the application and development of plastic film has been very rapid, and the effect of increasing production and income has been particularly significant. In 1979, small...
