Problems solved by technology

[0004] In view of the existing titanium dioxide and other metal oxide matting agents used in fiber-grade polycaprolactam materials, there are uneven dispersion, instability, and increased polycaprolactam The processing cost of caprolactam affects defects such as the performance of polycaprolactam. The first purpose of the present invention is to provide a kind of caprolactam miscibility, stable dispersion, good matting performance, and does not affect the performance of polycaprolactam impact strength and tensile strength. , an inexpensive matting agent

Abstract

The invention discloses a delustering agent, and a delustering nylon 6 material and a preparation method thereof, wherein the delustering agent comprises a melamine cyanurate generated by a reaction of a melamine compound and a cyanuric acid compound. The method for preparing a fiber-grade delustering nylon 6 material by adopting the delustering agent comprises: adding a melamine compound, a cyanuric acid compound, dicarboxylic acid, a binary primary amine and water into a molten caprolactam liquid, and carrying out shearing dispersing to obtain a dispersion liquid; and feeding the dispersionliquid and molten caprolactam liquid into a polymerization system, and carrying out ring-opening polymerization to obtain the delustering nylon 6 material. According to the invention, the delusteringagent has advantages of low cost, intersolubility with caprolactam, stable dispersion and good delustering performance, and the prepared polycaprolactam has good mechanical properties, such as excellent impact strength, excellent tensile strength and the like.

Description

technical field [0001] The invention relates to a matting agent, in particular to a matting agent containing a triazine structure, and a matting nylon 6 material prepared by using a triazine matting agent and a preparation method of the matting nylon 6 material, belonging to the technical field of nylon 6 material preparation. Background technique [0002] According to the classification of the industry standard "FZ / T5104-2011 Fiber Grade Polycaprolactam Slices", nylon 6 slices are generally divided into glossy (the mass percentage of titanium dioxide is less than or equal to 0.05%), semi-dull (mass percentage of titanium dioxide is greater than 0.1% and less than 0.6%) and full-dull slices (mass percentage of titanium dioxide is greater than or equal to 1.2%); using these slices can be made respectively Bright, semi-dull Dull and full-dull filaments and their engineering plastics. [0003] There are two existing methods for preparing nylon matting slices: one is to use tit...
