Abstract
The invention relates to a preparing method of a high-temperature levelling agent, and belongs to the technical field of spinning. According to the preparing method, diisopropanol amine and dimethylolpropionic acid are taken as mixed monomers and react with cyclodextrin and the like, a catalyst is adopted for catalysis, a hyperbranched polyester block cyclodextrin substance is formed, a very largecavity is formed in the formed hyperbranched polyester, and many active hydroxide radicals are formed on the surface of the hyperbranched polyester; then the hyperbranched polyester is mixed with a modifying agent formed by butanedioic anhydride and lysine, under the effect of the modifying agent, the content of carboxyl groups on the surface of the polymer can be increased, and the activity is improved; afterwards, glycerinum, cardanol and the like are mixed, and under the effect of a catalyst A, a cardanol-like glyceryl ether substance is formed; finally, the cardanol-like glyceryl ether substance is mixed with the polymer, dimethylformamide, an auxiliary material, an auxiliary agent and the like, wherein the polymer is utilized for triggering a reaction to form polymer-amphiphilic hyperbranched cardanol polyglycidol, and besides, through the utilization of the auxiliary material and the auxiliary agent, the types of active groups can be increased. By means of the preparing method,the problems that current levelling agents have a poor levelling effect and are hard to degrade are solved.
