Anti-aging shading screen cloth

Abstract

The invention discloses a piece of anti-aging shading screen cloth. The cloth comprises a three-layer composite screen cloth structure: an outer anti-ultraviolet layer screen cloth, an inner anti-microbial layer screen cloth, and an intermediate elastic layer screen cloth; the outer anti-ultraviolet layer screen cloth comprises the following spinning materials in percentages by mass: 40-60% of polyester fiber, 10-20% of copper ion fiber, and the balance being corn fiber; the inner anti-microbial layer screen cloth comprises the following spinning materials in percentages by mass: 30-60% of polyester fiber, 10-20% of silver ion fiber, and the balance being anti-microbial vegetable fiber; the intermediate elastic layer screen cloth comprises the following spinning materials in percentages bymass: 20-40% of polyether ester elastic fiber, 30-50% of polyolefin elastic fiber, and the balance being a two-component composite crimped fiber. Compared with the prior art, the product is advantageous in that ultraviolet resistance is high, addition of other micromolecular anti-ultraviolet absorbents with easy volatile migration is avoided, chemical performance of the finished product is stable, generation of volatile migration is not easy, the product has lasting anti-ultraviolet absorption property and shading performance, and the product has long service life, aging resistance, and corrosion resistance.

Description

technical field [0001] The invention relates to a sunshade mesh cloth, in particular to an anti-aging sunshade mesh cloth. Background technique [0002] Sunshade 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, PVC, recycled materials, new materials, etc., and is prepared by UV stabilizer and anti-oxidatio...

AI Technical Summary

Problems solved by technology

In fact, the main material for the preparation of traditional sunshade mesh does not have the ability to resist ultraviolet rays, and the effect of shading can only be achieved through the action of ultraviolet absorbers or stabilizers. This method of simply adding ultraviolet absorbers usually has certain disadvantages. Many Anti-ultraviolet absorbers such as benzophenone compounds are small molecular organic compounds, which are prone to volatilization and migration problems, resulting in the rapid reduction of the anti-ultraviolet ability and light-shielding ability of the prepared shading mesh during use, thus It affects its service life and is prone to aging
