Abstract

The invention relates to a constant-temperature polyethylene composite material and a production method thereof, and the constant-temperature polyethylene composite material can be particularly applied to various fields of cotton quilts in agricultural greenhouses, emergency tents, travelling tents, disaster relief tents, oilfield pipeline laying, coal mine induced air hoods, building heat insulation materials and the like. A constant temperature polyethylene composite material is of a multilayer structure and comprises the following components from outside to inside: the self-cleaning thermal insulation material comprises a first thermal insulation layer, a self-cleaning layer, an ageing layer, a first reinforcing layer, a polyethylene foam film, a second reinforcing layer, a second thermal insulation layer and a dripping layer, wherein the materials of all the layers are low-density polyethylene; the invention has the beneficial effects that: 1) each layer of the composite material is made of low-density polyethylene material, so that the composite material is waterproof, flame-retardant, resistant to ultraviolet irradiation, wear-resistant, durable, lower in cost, better in performance, stable in structure, degradable, green, environment-friendly and pollution-free; 2) the mesh cloth is used as the reinforcing layer, so that the strength is good and the service life is long.
