Functional master batch, preparation method thereof and application of functional master batch in preparation of polyester monofilament

Abstract

The invention discloses a functional master batch, a preparation method thereof and application of the functional master batch in preparation of a polyester monofilament. The functional master batch is prepared from the following raw materials in parts by weight: 100 parts of polyester chips, 6 to 9 parts of compatilizer, 10 to 15 parts of inorganic filler, 0.1 to 1 part of oiling agent, 0.5 to 1.5 parts of anti-hydrolysis agent and 0.2 to 0.4 part of antioxidant, The compatilizer is a mixture of an ethylene-methyl acrylate copolymer and linear polyethylene, and the weight ratio of the ethylene-methyl acrylate copolymer to the linear polyethylene is (2-3): (4-6). When the functional master batch is added into a polyester monofilament reaction system taking high-viscosity polyester chips as a main raw material, the flowability and the spinnability of a high-viscosity spinning melt can be solved, and the wear resistance and the use durability of the polyester monofilament are improved. The polyester monofilament prepared by the method is smooth in surface, uniform in dry heat shrinkage, wear-resistant, fatigue-resistant, good in weaving performance and high in yield.

Description

technical field [0001] The invention belongs to the technical field of monofilaments, and in particular relates to a functional masterbatch, a preparation method thereof and an application in preparing polyester monofilaments. Background technique [0002] Due to poor melt fluidity, high melt viscosity, and large swelling effect of high-viscosity polyethylene terephthalate, the spinnability of the material is poor and the diameter of the monofilament is uneven. In foreign countries, it is a hot spot in recent years to carry out technical research on this kind of high-strength and wear-resistant polyester fiber monofilament. However, this type of product is expensive. If you rely on imports, it will cause a lot of cost to paper-making net manufacturers. pressure. In foreign countries, the development and initial application of some emerging materials have improved the performance of monofilaments and provided a direction for future development. For example, PEEK, PPS, etc.,...
