Abstract

The invention provides a preparation method of a polyether compound serving as a polyamide adjuvant. The preparation method comprises the following steps: adding polyether, vinyl triethoxysilane, (Z)-11-eicosene amide, 9,9-dis[4-(2-acryloyloxy ethyoxyl) phenyl] fluorene and the like, and carrying out reaction to obtain a product.

Description

technical field [0001] The invention relates to a preparation method of a polyamide auxiliary agent, in particular to a preparation method of a polyether compound used as a polyamide auxiliary agent. Background technique [0002] Polyamide is commonly known as nylon. Polyamide is mainly used in synthetic fibers. Its most prominent advantage is that its abrasion resistance is higher than that of all other fibers, 10 times higher than cotton, 20 times higher than wool, and a little added to blended fabrics. Polyamide fiber can greatly improve its wear resistance; when stretched to 3-6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of times of bending without breaking. [0003] Adding flame retardants in the nylon production process can improve the flame retardancy of nylon products, thereby improving the safety performance of nylon-related products and expanding the application fields of products. [0004] CN103304992B discloses a flame-retarda...
