Problems solved by technology

In recent years, inorganic ultraviolet shielding agents have become a hot spot in anti-ultraviolet research. It uses fine powder of inorganic substances such as titanium dioxide and zinc oxide to combine with fabrics through adhesives to increase the reflection and scattering of ultraviolet rays on the surface of the fabric and play an anti-ultraviolet effect. The effect of this kind of anti-ultraviolet finishing agent is that it feels hard and has poor air permeability when it is finished on the textile.

Embodiment 1

[0028] 1. Add 11.78g of methyl hydrogen-containing silicone oil, 0.78g of acrylamide and 12.00g of allyl polyoxyethylene polyoxypropylene ether into a reaction vessel equipped with a stirrer, a thermometer and a condensing reflux tube, and stir. After heating until the solid is completely dissolved, add 0.60 g of chloroplatinic acid solution, and raise the temperature to 90°C under the protection of nitrogen. After reacting for 4 hours, remove low boilers under reduced pressure, cool the product to room temperature, and use 29.50 g of methanol-acetone The mixed solvent (the volume ratio of methanol to acetone is 5:1) is fully washed, the mixed solvent is removed under reduced pressure, and the obtained product is vacuum-dried at 78-82°C to obtain intermediate I.

Abstract

The invention discloses an anti-ultraviolet soft finishing agent for textiles as well as a preparation method and application of the anti-ultraviolet soft finishing agent. The preparation method comprises the following steps: using methyl hydrogen silicone oil, acrylamide and allyl polyoxyethylene polyoxypropylene ether as raw materials, and using chloroplatinic acid as a catalyst for synthesizing an intermediate I; synthesizing an intermediate II by cyanuric chloride and resorcinol under the catalytic action of aluminum trichloride; finally, reacting the intermediate I with the intermediate II to obtain the anti-ultraviolet soft finishing agent. According to the anti-ultraviolet soft finishing agent disclosed by the invention, organic ultraviolet absorbents are grafted to a polysiloxane chain; the ultraviolet resistance of the textiles is remarkably improved by triazine ultraviolet absorption groups in molecules of the obtained anti-ultraviolet soft finishing agent; meanwhile, by using a siloxane chain, the textiles have soft hand feeling, and the defects of an inorganic ultraviolet screening agent can be effectively overcome. The anti-ultraviolet soft finishing agent disclosed by the invention has the advantages of simpler process and lower cost.

Description

technical field [0001] The invention belongs to the technical field of synthesis of textile printing and dyeing auxiliaries, and in particular relates to an anti-ultraviolet softening agent for textiles and a preparation method thereof. Background technique [0002] Ultraviolet rays are easier to pass through textiles, and the lighter and thinner the textiles, the easier it is for ultraviolet rays to pass through; in hot summer, light and comfortable textiles are people's first choice, but summer ultraviolet radiation is the strongest; therefore, anti-ultraviolet radiation finishing of textiles most urgent. In recent years, inorganic ultraviolet shielding agents have become a hot spot in anti-ultraviolet research. It uses fine powder of inorganic substances such as titanium dioxide and zinc oxide to combine with fabrics through adhesives to increase the reflection and scattering of ultraviolet rays on the surface of the fabric and play an anti-ultraviolet effect. The effect...
