Preparation method of shading screen cloth with antibacterial and antiageing performances

Abstract

The invention discloses a preparation method of shading screen cloth with antibacterial and antiageing performances. The prepared shading screen cloth is of a double-layered composite structure. The preparation method comprises the following steps: firstly, separately synthesizing outer screen cloth of an anti-ultraviolet layer and inner screen cloth of an antibacterial layer; then preheating and melting the two screen cloth through adjustment variation of the temperature of a heating roller, and assisted by an adhesive, pressing a rubber roller with an iron roller, and forming cooling forming to boating the shading screen cloth. The shading screen cloth of the double-layered composite structure is directly prepared from functional composite high molecular fibers separately without adding an anti-ultraviolet agent and an antibacterial agent. A finished product not only has an excellent anti-ultraviolet function, but also has a strong antibacterial and anti-mold property, is stable in chemical property, and also avoids use of external additives. Various stretch resisting, anti-ageing, corrosion-resisting, radiation-resisting and light characteristics of the screen cloth are guaranteed to the maximum.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a method for preparing a light-shielding mesh cloth with antibacterial and anti-aging properties. Background technique [0002] Shade net, also known as shading net, is the latest type of protective covering material for agriculture, fishery, animal husbandry, windproof, and soil cover that has been promoted in the past 10 years. After covering in summer, it plays a role of blocking light, rain, moisturizing and cooling. There is also a certain effect of heat preservation and humidification after covering in winter and spring. It is mainly used for the protective cultivation of vegetables, shiitake mushrooms, flowers, edible fungi, seedlings, medicinal materials, ginseng, ganoderma and other crops and aquatic poultry breeding, etc., and has obvious effects on increasing production. [0003] The traditional sunshade net is made of polyethylene, high-density polyethylene, PE, PB,...

AI Technical Summary

Problems solved by technology

In fact, the main material fiber of the traditional sunshade net does not have the ability of anti-ultraviolet, anti-bacterial and anti-mildew, and the corresponding effect can only be achieved through the action of external additives. However, the method of external additives has certain disadvantages, and it is difficult to choose two external additives at the same time. The additives all achieve the best synergy with the main material
