Problems solved by technology

However, a series of new problems also arise. During their production, transportation, storage and use, these materials are prone to yellowing, brittleness and cracking under the action of oxygen, water and ultraviolet rays in the air. And stickiness and other phenomena, which will lead to the decline of the appearance and mechanical properties of the material, affect the use, and cause the degradation and aging of polymer materials

Embodiment i

[0035] Weigh 53.0g of light stabilizer 3346 and dissolve it in 300mL of toluene, and add the above solvent into the autoclave, then add 8g of sodium hydroxide in 100mL of aqueous solution, slowly add 31.8g of 2-(2-hydroxy-5-bromomethyl Base-3-methylphenyl)-benzotriazole 200mL toluene solution, the air in the kettle was replaced with nitrogen three times, the temperature was slowly raised to 110°C, and the reaction was stirred for 16 hours. After the reaction, the water layer was separated, the organic phase was washed 3 times with 100 mL of deionized water, the toluene was evaporated under reduced pressure, and the concentrated solution was naturally cooled to precipitate a light yellow solid I. The measured product number average molecular weight: 2827.

[0036] Example II

[0037] Weigh 53.0g light stabilizer 3346 and dissolve it in 300mL toluene, add the above solvent into the autoclave, then add 100mL aqueous solution of 8g sodium hydroxide, slowly add 63.6g 2-(2-hydroxy-...

Abstract

The invention belongs to the field of high polymer material auxiliaries, and particularly relates to a multifunctional light-stable composition and a preparation method thereof, wherein the light stabilizer is a polymer shown as a formula I, and n is 2-10. According to the light-stable composition, the light stabilizer shown in the formula I and other auxiliaries are compounded and mixed, and the light stabilizer shown in the formula I has multiple functional groups, so that the application range can be greatly widened, the light-stable composition has good anti-aging performance on multiple materials, the light-stable composition has a good synergistic effect with all the components mixed with other substances, after compounding, the composition has better compatibility with most high polymer materials, volatilization and migration in the using process can be effectively prevented, the lasting and stable effect is kept, and the aging resistance of the polymer is effectively improved.

Description

technical field [0001] The invention belongs to the field of polymer material additives, and in particular relates to a multifunctional photostable composition and a preparation method thereof. Background technique [0002] With the step-by-step development of science and technology, the use of polymer materials such as plastics, rubber, resins and fibers has become more and more extensive. These polymer materials are highly irreplaceable in many fields, and people rely more and more on polymer materials. However, a series of new problems also arise. During their production, transportation, storage and use, these materials are prone to yellowing, brittleness and cracking under the action of oxygen, water and ultraviolet rays in the air. And stickiness and other phenomena, which will lead to the decline of the appearance and mechanical properties of the material, affect the use, and cause the degradation and aging of polymer materials. [0003] With the destruction of the a...
