Embodiment 1

[0061] 1) Preparation of cationic silicone acrylic emulsion by emulsion polymerization

[0062] (1) Preparation of pre-emulsion: mix 7 g butyl acrylate, 18 g methyl methacrylate, 1.2 g vinyl triethoxy silane, 1.5 g vinyl-terminated silicone oil with a viscosity of 200 ± 30 cP, 1.5 g N-(isobutoxymethyl)acrylamide and 0.9 g and hydroxyethyl methacrylate are mutually dissolved as the oil phase; add 0.9 g 1227 and 2.4 g Pingping O-15, 0.5 g glacial acetic acid, and dissolve in 30 g. Ionized water is used as the water phase. Mix the water phase and the oil phase, quickly stir and pre-emulsify at room temperature, where the temperature does not exceed 40°C, the stirring speed is 1200 rpm, and the stirring time is 35 minutes.

[0063] (2) Prepare the primer: add 0.1 g 1227 and 0.9 g Pingping O-15 (23% of the total emulsifier mass), 0.125 g azobisisobuimidazoline hydrochloride and 40 g deionized water , Stir and dissolve evenly at room temperature. Put all the primers into a four-necked...

Embodiment 2

[0070] Step 1) According to Example 1, change the hard monomers to 6 g methyl methacrylate and 12 g styrene, and change the silicone to 1.5 g 3-methacryloxypropylmethyldimethoxysilane And 1.2 g of vinyl-terminated silicone oil with a viscosity of 300±20 cP, and change the corresponding cationic emulsifier in the pre-emulsion and primer to 1831;

[0071] Steps 2) and 3) are the same as in Example 1. The solid content of the finishing agent was measured to be 49.2%, and the pH value was 4.9.

Embodiment 3

[0073] Step 1) Same as Example 1;

[0074] Step 2) According to Example 1, change the ultraviolet absorbers used to 40 g EHA, 15 g UV-1130 and 30 gUV-531;

[0075] Step 3) Same as Example 1. The solid content of the finishing agent was 48.5% and the pH value was 5.6.

Abstract

The invention discloses a durable uvioresistant finishing agent applicable to both cotton and terylene and a preparation method thereof. The durable uvioresistant finishing agent applicable to both cotton and terylene comprises, in percent by mass, 60-85% of a cationic silicone-acrylic emulsion and 15-40% of an ultraviolet-ray absorber solution. The preparation method for the durable uvioresistant finishing agent comprises the following steps: preparing the cationic silicone-acrylic emulsion through an emulsion polymerization reaction, preparing the ultraviolet-ray absorber solution, and mixing the ultraviolet-ray absorber solution and the silicone-acrylic emulsion, and performing emulsification. The durable uvioresistant finishing agent is universally applied to cotton, terylene, polyester cotton and other fabric with highest demand, and also is universally applied to technologies of dip padding, dipping, coating, printing, spraying and the like. The product storage stability is excellent. Fabric arranged by employing the finishing agent is excellent in ultraviolet resistance and excellent in washing fastness.

Description

Technical field [0001] The invention belongs to the technical field of textile dyeing and finishing auxiliaries, and specifically relates to a durable anti-ultraviolet finishing agent commonly used for cotton and polyester and a preparation method thereof. Background technique [0002] In view of the harmfulness of ultraviolet light to the human body, the human body's anti-ultraviolet radiation has received more and more attention. Clothing is the most effective protective product for the human body, so it is necessary to carry out anti-ultraviolet finishing of textiles. At present, countries such as Japan, the United States, Germany, and the Netherlands have even included the anti-ultraviolet function of elementary school student clothing in the legal provisions, which shows the importance of fabric anti-ultraviolet. [0003] As we all know, cotton fabrics and polyester fabrics are the two most widely used textiles in the world. Because polyester fabric contains benzene ring in i...
