Abstract

The invention discloses a uvioresistant polyethylene non-woven fabric. A polydopamine layer and a titanium dioxide layer are sequentially adhered to the surface of the polyethylene non-woven fabric. The invention also discloses a preparation method of the uvioresistant polyethylene non-woven fabric, which comprises the following steps of S1, soaking the polyethylene non-woven fabric in a dopamine solution, washing, and drying to obtain an intermediate fabric; and S2, soaking the intermediate fabric in the titanium dioxide dispersion liquid, washing and drying to obtain the uvioresistant polyethylene non-woven fabric. The uvioresistant polyethylene non-woven fabric provided by the invention has high ultraviolet resistance and antibacterial performance, and good mechanical properties.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to an anti-ultraviolet polyethylene nonwoven fabric and a preparation method thereof. Background technique [0002] Polyethylene (referred to as PE) is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, low temperature resistance, good chemical stability, and easy to process. It is often used as the raw material of non-woven fabrics for the production of packaging bags and other products; however, polyethylene is prone to degradation under the action of ultraviolet rays, which limits its use. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an anti-ultraviolet polyethylene nonwoven fabric and a preparation method thereof. The present invention has good anti-ultraviolet performance and antibacterial performance, and good m...
