Problems solved by technology

The second aspect refers to that during the use of amide wax, due to the easy hydrolysis of the -CONH- group in the amide wax molecule and the low molecular weight of the amide wax, it causes its own yellowing, which in turn affects the color of the final product
Susceptibility to yellowing severely limits the use of amide waxes in masterbatches and white composites

Embodiment 1

[0020] Take 100 grams of AS1801, 0.5 grams of solid activator, 5 grams of accelerator, 0.1 gram of antioxidant, 1 gram of α, β-unsaturated acid, 0.01 gram of inhibitor and 0.1 gram of initiator tape In a four-necked flask with a stirrer, a thermometer, a condenser and an equal pressure funnel, place the four-necked flask in a programmed temperature-controlled oil bath. Get 5 grams of ethylenediamine and place it in an equal pressure funnel. With the agitator in a stirring state and the system under nitrogen protection, turn on the programmed temperature control device to heat the oil bath, and when the temperature of the system rises to 110°C, add ethylenediamine dropwise. During the dropwise addition of ethylenediamine, the temperature in the reaction system should be controlled below 150°C. After the ethylenediamine is added dropwise, keep it at about 150°C for 1 hour, then raise the temperature of the system to 190°C, and keep it for 6 hours. The temperature of the system...

Abstract

The invention provides anti-yellowing amide wax and a preparation method thereof. The anti-yellowing amide wax is prepared from the following raw materials in parts by weight: 100 parts of C18 stearicacid, 0.5-2 parts of a solid activator, 5-25 parts of an accelerant, 0.1-0.5 part of an antioxidant, 1-10 parts of alpha,beta-unsaturated acid, 0.01-0.05 part of a polymerization inhibitor, 0.1-0.5 part of an initiator and 5-25 parts of ethanediamine. According to the anti-yellowing amide wax and the preparation method thereof, compared with amide wax prepared by a conventional process, the prepared anti-yellowing amide wax is high in whiteness, low in color value, few in by-products and high in purity, and has excellent anti-yellowing property in the using process.

Description

technical field [0001] The invention relates to the fields of polymer materials and the like, in particular to an anti-yellowing amide wax and a preparation method thereof. Background technique [0002] Amide wax represented by ethylene bisstearamide (N,N-Ethylenebisstearamide, referred to as EBS) is one of the most important processing aids for polymer materials. Anti-sticking, significantly improving the surface smoothness of products, improving and improving the dispersion performance of fillers such as dyes (toners) in base resins, and improving the processing fluidity of materials. It has a wide range of applications in the fields of polymer materials such as plastics, coatings, rubber, and chemical fibers. With the continuous expansion of the application field of polymer materials, higher and higher requirements are put forward for the performance of amide waxes. In particular, the easy-yellowing performance of amide wax has seriously affected its application fields ...
