Description

Technical Field

[0001] This invention relates to polyphenylene sulfone composite dyeing materials, and more particularly, to a glass microbead-reinforced polyphenylene sulfone composite dyeing material and its preparation method. Background Technology

[0002] Polyphenylsulfone (PPSU) is a high-performance special engineering material with excellent heat resistance, hydrolysis resistance, and impact resistance, and is widely used in medical, food contact, aerospace, and electronic and electrical fields. To enhance aesthetics, manufacturers mix color powders with PPSU for composite dyeing. Achieving uniform dispersion and strong bonding of color powders within the PPSU matrix remains a current technical challenge. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing polyphenylene sulfone composite dyeing materials have uneven dispersion of pigments, and a novel glass microbead reinforced polyphenylene sulfone composite dyeing material and its preparation method are provided.

[0004] To achieve this objective, the technical solution of the present invention is as follows: a glass microsphere-reinforced polyphenylene sulfone composite dyeing material, the raw materials for which include: 78-80 parts by weight of polyphenylene sulfone, 20-21 parts by weight of hollow glass microspheres, 0.5-0.6 parts by weight of silane coupling agent, 0.2-0.25 parts by weight of wetting and dispersing agent, 0.5-0.6 parts by weight of lubricant, and 0.5-0.6 parts by weight of color powder, wherein the color powder is selected with a heat resistance ≥300°C. The beneficial effect is at least that it enables uniform dispersion and firm bonding of the color powder within the PPSU matrix. The hollow glass microspheres act as "ball bearings," aiming to reduce melt viscosity and enhance processing fluidity. The silane coupling agent is used to improve the interfacial compatibility and adhesion between the hollow glass microspheres and the PPSU matrix. The wetting and dispersing agent anchors to the surface of the color powder, utilizing steric hindrance to prevent agglomeration and ensuring uniform and stable dispersion of the color powder in the melt, thereby obtaining a final product with uniform color and a smooth surface. The lubricant further enhances the ability of the color powder to disperse uniformly and stably in the melt.

[0005] As a preferred embodiment of the glass microsphere-reinforced polyphenylsulfone composite dyeing material, its raw materials include: 78 parts by weight of polyphenylsulfone, 20 parts by weight of hollow glass microspheres, 0.5 parts by weight of silane coupling agent, 0.2 parts by weight of wetting and dispersing agent, 0.5 parts by weight of lubricant, and 0.5 parts by weight of pigment. The beneficial effect is at least that it provides the best embodiment.

[0006] As a preferred option for glass microsphere-reinforced polyphenyl sulfone composite dyeing materials, the raw materials for preparation further include: 0.7-0.8 parts by weight of antioxidant 1010 and 0.3-0.4 parts by weight of antioxidant 168. The beneficial effects are at least as follows: the combined use of antioxidant 1010 and antioxidant 168 provides far more efficient antioxidant protection than when used alone, throughout the entire processing and long-term service life, ensuring the material's performance stability under harsh environments.

[0007] As a preferred option for glass microsphere-reinforced polyphenylsulfone composite dyeing materials, 3M's iM16K hollow glass microspheres are selected. The advantages include at least providing a specific selection method for hollow glass microspheres.

[0008] As a preferred option for glass microsphere-reinforced polyphenylsulfone composite dyeing materials, KH550 is selected as the silane coupling agent. The beneficial effect is at least that it provides a specific selection method for silane coupling agents.

[0009] As a preferred option for glass microsphere-reinforced polyphenylsulfone composite dyeing materials, BYK-102 from BYK Corporation is selected as the wetting and dispersing agent. The beneficial effect is at least that it provides a specific selection option for the wetting and dispersing agent.

[0010] As a preferred option for glass microsphere-reinforced polyphenylsulfone composite dyeing materials, Clariant's Licowax PED521 lubricant is selected. The advantage lies at least in providing a specific lubricant selection.

[0011] As a preferred option for glass microbead-reinforced polyphenylsulfone composite dyeing materials, the pigments selected are Heliogen® Blue L 6700F (PB15:3), Heliogen® Green L 8605 (PG7), Hostaperm® Red E5B 02 (PR122 quinacridone red), Paliotan® Yellow 2140 HD (PY139 isoindolinone yellow), Black Pearls® 800 (high-pigment carbon black), and Ti-Pure™ R-105 (rutile titanium dioxide). The benefit lies at least in providing specific pigment selection options.

[0012] Another technical solution of the present invention is as follows: A method for preparing the glass microsphere-reinforced polyphenylene sulfone composite dyeing material, comprising:

[0013] Mixing steps: The color powder and wetting and dispersing agent are mixed to obtain a color powder mixture; then the color powder mixture, polyphenylene sulfone, hollow glass microspheres, silane coupling agent and lubricant are mixed to obtain a raw material mixture;

[0014] Mixing step: The raw material mixture is mixed at high temperature;

[0015] Cooling steps; and,

[0016] Dicing step.

[0017] The beneficial effects are at least that it enables the uniform dispersion and firm bonding of pigments within the PPSU matrix.

[0018] In the preferred method for preparing glass microsphere-reinforced polyphenylsulfone composite dyeing materials, the high temperature range during the mixing step is controlled at 300-360℃. The beneficial effect is at least that it provides a specific selection of the high temperature range.

[0019] In the preferred method for preparing glass microsphere-reinforced polyphenylsulfone composite dyeing materials, the high temperature range during the mixing step is controlled at 320-325℃. The beneficial effect is at least that it further improves the uniform dispersion of the pigment. Detailed Implementation
