Embodiment 1

[0024] S1. Preparation of acetoacetyl-functionalized cellulose: 10 grams of cellulose and 10 grams of tert-butyl acetoacetate were dissolved in 200 ml of dimethyl sulfoxide, and reacted at 150° C. for 12 hours. After cooling, the above solution was poured into 1500 ml of ethanol to precipitate the acetoacetyl-functionalized cellulose, which was dried in a vacuum oven at 40° C. for 24 hours.

[0025] S2. Preparation of anti-ultraviolet aging coating sol solution: the acetoacetyl-functionalized cellulose obtained in step S1 and 1,8-octanediamine are dissolved in dimethylmethylene in a mass ratio of 10:3 as an amino accelerator In sulfone, a homogeneous solution with a concentration of 5% was prepared to prepare a sol solution of anti-ultraviolet aging coating, and its ultraviolet transmittance was measured;

[0026] S3. Preparation of anti-ultraviolet aging coating: coating the gel solution of anti-ultraviolet aging coating on the surface of poly-m-phenylene isophthalamide (meta...

Embodiment 2

[0028] The difference from Example 1 is that in step S2, the acetoacetyl-functionalized cellulose and polyetheramine D230 obtained in step S1 are amino accelerators and are dissolved in dimethyl sulfoxide with a mass ratio of 10:1. , configured into a homogeneous solution with a concentration of 3% to prepare an anti-ultraviolet aging coating sol solution, and measure its ultraviolet transmittance.

Embodiment 3

[0030] The difference from Example 1 is that the mass ratio of acetoacetyl-functionalized cellulose and polyetheramine D230 as amino accelerator is 10:2, and other conditions are not changed.

Abstract

The invention provides an anti-ultraviolet aging coating and a preparation method thereof, and belongs to the technical field of polymer, and the preparation method comprises the following steps: S1, preparing acetoacetyl functionalized cellulose; s2, preparing a sol solution of the anti-ultraviolet aging coating; and S3, preparing the anti-ultraviolet aging coating. According to the method disclosed by the invention, the poly (m-phenylene isophthalamide) (meta-aramid) anti-ultraviolet aging coating sol can be prepared, and poly (m-phenylene isophthalamide) (meta-aramid) fibers and products thereof can be directly coated, so that the anti-ultraviolet aging performance of the poly (m-phenylene isophthalamide) (meta-aramid) fibers and the products thereof is improved; the method has the technical advantages of high universality, low cost, simple synthesis, low raw material cost and the like.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to an anti-ultraviolet aging coating and a preparation method thereof. Background technique [0002] Poly-m-phenylene isophthalamide fiber (aramid 1313) is a kind of high temperature resistant fiber with early development, wide application, large output and rapid development, and its total amount ranks second in special fibers. However, because it is also a light-sensitive polymer material, it is prone to aging and degradation under the irradiation of ultraviolet rays, which greatly affects its use range and service life. Therefore, using an appropriate anti-ultraviolet aging agent to protect it and block the damage of ultraviolet light can improve the service life of the poly-m-phenylene isophthalamide fiber and its products. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a kind of anti-ultraviolet aging coating and preparation method ther...
