Embodiment 1～9

[0036] The embodiment of the nylon with high color stability of the present invention, the preparation method of the product, comprises the following steps:

[0037] After the dried components are uniformly mixed according to the proportions, they are put into a twin-screw extruder, melt-blended at 230° C. and extruded and pelletized to obtain the nylon with high color stability.

[0038] The raw materials used in each example are as follows, and the proportions of the raw materials are shown in Table 1.

[0039] PA6 resin: high viscosity PA6 resin, grade HY-2800;

[0040] Glass fiber: chopped glass fiber, grade Chongqing glass fiber ECS301HP-3-H;

[0041] Antioxidant: Antioxidant 1098;

[0042] Nucleating agent: nucleating agent LICOMONT NAV101 PWD;

[0043] Lubricant: Wuhan Hyperbranched HyperC100;

[0044] White powder: zinc sulfide;

[0045] Red Pink A: Naphthalene red;

[0046] Red Pink B: Cerium sulfide.

Embodiment 10

[0048] The only difference between this example and Example 9 is that the lubricant used is replaced with lubricant A-C540A.

Abstract

The invention discloses nylon with high color stability and a preparation method thereof, belonging to the field of nylon material reinforcement. After the nylon product of the present invention introduces glass fiber as a reinforcing component, the product is modified by using a specific content of cerium sulfide as a coloring material, the resulting nylon is firmly colored, and the discoloration after moisture absorption is significantly improved; at the same time, each component The synergistic effect promotes the heat resistance, weather resistance and stability of the obtained nylon to be effectively enhanced, and the comprehensive performance is excellent. The invention also discloses a preparation method of the nylon. The preparation method has simple operation steps and can realize industrialized large-scale products.

Description

technical field [0001] The invention relates to the field of nylon material reinforcement, in particular to a nylon with high color stability and a preparation method thereof. Background technique [0002] PA6, also known as nylon 6, is a common translucent or opaque milky white particle polymer product. It is generally used in auto parts and mechanical parts due to its thermoplasticity, light weight, good toughness, chemical resistance and durability. , electronic and electrical products and engineering accessories and other products. Specifically, PA6 has the following advantages: (1) the material has excellent mechanical strength, rigidity and durability, and also exhibits good thermal stability; (2) the material has strong processability, excellent fluidity and The thermal stability makes the processing conditions of the material itself more relaxed, which can miniaturize the injection molded parts; (3) the material has a perfect surface appearance, which can be suitabl...
