Embodiment 1～9

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

[0037] After the dried components are uniformly mixed according to the proportion, they are placed in a twin-screw extruder, melted and blended at 230° C., extruded and granulated to obtain the nylon with high color stability.

[0038] The raw materials used in each embodiment are as follows, and the proportioning ratio of the raw materials is 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 powder A: Naphthalene red;

[0046] Red powder B: cerium sulfide.

Embodiment 10

[0048] The difference between this embodiment and embodiment 9 is that the lubricant used is replaced by lubricant A-C540A.

Abstract

The invention discloses nylon with high color stability and a preparation method thereof, and belongs to the field of nylon material reinforcement. According to the nylon product disclosed by the invention, after the glass fiber is introduced as a reinforcing component, the product is modified by taking the cerium sulfide with a specific content as a pigment, so that the obtained nylon is firm in coloring, and the color change condition after moisture absorption is obviously improved; meanwhile, all the components have a synergistic effect, so that the heat resistance, the weather resistance and the stability of the obtained nylon are effectively enhanced, and the comprehensive performance is excellent. The invention also discloses the preparation method of the nylon, the preparation method is simple in operation steps, and industrial large-scale products can be realized.

Description

technical field [0001] The invention relates to the field of nylon material reinforcement, in particular to 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 while also exhibiting good heat resistance stability; (2) The material has strong processability, excellent fluidity and 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, can be applied ...
