Description

Technical Field

[0001] This application relates to the technical field of ceramic materials, and particularly to an organic ceramic material, a preparation method thereof, and an organic ceramic product. Background Art

[0002] Organic ceramics are a new type of composite material that combines an organic phase and an inorganic ceramic phase. The ceramic phase can improve the strength, hardness, heat resistance, corrosion resistance, etc. of the material, and the organic phase endows the material with flexibility. As a result, organic ceramics not only have good mechanical properties and excellent heat and corrosion resistance, but also have excellent wear resistance and flexibility, so they have broad application prospects in many fields. However, organic ceramics have the problem of low gloss, which greatly limits the application range of organic ceramics. Summary of the Invention

[0003] Based on this, it is necessary to provide an organic ceramic material with high gloss, a preparation method thereof, and an organic ceramic product.

[0004] In one aspect of this application, a preparation method of an organic ceramic material is provided, including the following steps:

[0005] The organic ceramic powder is successively subjected to internal mixing injection molding and heat treatment to obtain the organic ceramic material; wherein, the organic ceramic powder includes polyphenylene sulfide, zirconia, coupling agent, and color powder with a mass ratio of 1:1 - 4:0.01 - 0.05:0.03 - 0.05, and the average particle size of the zirconia is 0.5 µm - 3 µm.

[0006] The raw materials in the above preparation method adopt polyphenylene sulfide, zirconia, coupling agent, and color powder with a mass ratio of 1:1 - 4:0.01 - 0.05:0.03 - 0.05, and the average particle size of the zirconia is 0.5 µm - 3 µm. Through the mutual cooperation of specific components with specific ratios, the synergistic effect is enhanced, the interfacial bonding force and compatibility between the raw materials are improved, and the contact area between the raw materials during subsequent internal mixing injection molding and heat treatment is increased. Furthermore, the density and uniformity of the obtained organic ceramic material are better, and the gloss of the organic ceramic blank is improved. Among them, the use of zirconia with an average particle size of 0.5 µm - 3 µm makes the wrapping effect of polyphenylene sulfide on the particulate matter in the organic ceramic powder unexpectedly good, the particulate matter is evenly dispersed, and the plastic completely wraps the particulate matter, greatly improving the density and uniformity of the organic ceramic material; moreover, the use of zirconia with an average particle size of 0.5 µm - 3 µm well balances the strength, gloss, and mechanical properties of the organic ceramic material, making the finally obtained organic ceramic material not only have good gloss but also excellent strength performance.

[0007] The above preparation method broadens the application range of the organic ceramic material, making it applicable to fields with high requirements for the surface gloss of the organic ceramic material.

[0008] When a colorant is added to traditional ceramic materials, it is likely to deteriorate the mechanical properties of the ceramic materials during the heat treatment process. However, the above preparation method improves the density and uniformity of the organic ceramic materials through the mutual cooperation of specific components with specific ratios, compensates for the influence of the color powder on the mechanical properties, and improves the surface gloss of the organic ceramic materials on the premise of ensuring the mechanical properties of the organic ceramic materials, achieving unexpected effects.

[0009] In some of the embodiments, the mass ratio of the polyphenylene sulfide, zirconia, coupling agent, and color powder is 1:1.5 - 3:0.01 - 0.02:0.03 - 0.048.

[0010] In some of the embodiments, the average particle size of the zirconia is 0.5 µm - 1 µm.

[0011] In some of the embodiments, the molecular weight of the polyphenylene sulfide is 4000 - 5000; and / or, the melt index of the polyphenylene sulfide is 6 g / 10 min - 10 g / 10 min.

[0012] In some of the embodiments, the coupling agent includes at least one of γ-aminopropyltriethoxysilane, γ-(2,3-epoxypropoxy)propyltrimethoxysilane, and vinyltriethoxysilane; and / or, the color powder includes at least one of plastic color powder and ceramic color powder.

[0013] In some of the embodiments, the kneading temperature for kneading and injection molding is 300°C - 350°C; and / or, the temperature for heat treatment is 180°C - 200°C; and / or, the time for heat treatment is 2 h - 4 h.

[0014] In some of the embodiments, before the kneading and injection molding, the following steps are further included: grinding the polyphenylene sulfide and zirconia into a slurry in a solvent, then adding the coupling agent and the color powder to the slurry, grinding, and drying to obtain the organic ceramic powder.

[0015] In some of the embodiments, a polishing treatment step is further included. The polishing treatment sequentially includes rough polishing treatment, fine polishing treatment, and finishing polishing treatment. The rough polishing treatment is performed using a polyurethane polishing pad and a silica polishing liquid for surface polishing; and / or, the fine polishing treatment is performed using a wire wheel and white wax for polishing; and / or, the finishing polishing treatment is performed using a cloth wheel and red wax for polishing.

[0016] In the second aspect of the present application, an organic ceramic material is provided, which is prepared by using the preparation method of the organic ceramic material as described in the first aspect.

[0017] In a third aspect of the present application, an organic ceramic product is provided, which includes the organic ceramic material as described in the second aspect. Detailed implementation manners

[0018] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to relevant embodiments. Preferred embodiments of the present application are given in the text. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure content of the present application more thorough and comprehensive.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] The organic ceramic material has some characteristics of both organic materials and ceramic materials. In addition to having good mechanical properties and excellent heat resistance and corrosion resistance, it also has excellent wear resistance and flexibility. However, it has the problem of low gloss, which greatly limits the application range of organic ceramics. Currently, organic ceramics are mainly used in structural components such as circuit packaging, capacitors, electronic components, and aircraft. For some fields with high requirements for the surface gloss of materials, it is difficult to promote the application of organic ceramic materials, such as the field of decorative materials and the field of electronic product materials with high requirements for appearance quality.

[0021] Based on this, an embodiment of the present application provides a preparation method of an organic ceramic material, including the following steps:

[0022] The organic ceramic powder is subjected to kneading injection molding and heat treatment in sequence to obtain the organic ceramic material; wherein, the organic ceramic powder includes polyphenylene sulfide, zirconia, coupling agent, and color powder with a mass ratio of 1:1 to 4:0.01 to 0.05:0.03 to 0.05, and the average particle size of the zirconia is 0.5 µm to 3 µm.

[0023] The raw materials in the above preparation method are polyphenylene sulfide, zirconia, coupling agent and color powder with a mass ratio of 1:1-4:0.01-0.05:0.03-0.05, and the average particle size of zirconia is 0.5 µm-3 µm. Through the mutual cooperation of specific components with specific ratios, synergistic effects are achieved, improving the interfacial bonding force and compatibility between the raw materials, increasing the contact area between the raw materials during subsequent internal mixer injection molding and heat treatment, and further making the density and uniformity of the prepared organic ceramic material better, and improving the gloss of the organic ceramic blank. Among them, using zirconia with an average particle size of 0.5 µm-3 µm makes the wrapping effect of polyphenylene sulfide on the particles in the organic ceramic powder unexpectedly good, the particles are evenly dispersed, and the plastic completely wraps the particles, greatly improving the density and uniformity of the organic ceramic material; moreover, using zirconia with an average particle size of 0.5 µm-3 µm well balances the strength and gloss of the organic ceramic material, making the finally obtained organic ceramic material not only have good gloss, but also excellent strength performance.

[0024] The above preparation method broadens the application scope of organic ceramic materials, enabling them to be used in fields with high requirements for the surface gloss of organic ceramics.

[0025] After adding colorants to traditional ceramic materials, it is easy to cause deterioration of the mechanical properties of ceramic materials during the heat treatment process. For example, some metal salt colorants are prone to react with the active groups in organic ceramics, changing the reaction path, causing defects, pores or non-uniformity in the originally regular internal network structure of organic ceramics, and then reducing the strength and toughness of the materials; another example is some organic colorants, which are prone to form weak physical adsorption or chemical bonds with the ceramic matrix, and the strength of these bonds is lower than the chemical bonds of the ceramic itself. Under conditions such as stress or heat, they are prone to become the weak links of the materials, resulting in a decline in the performance of the materials. However, the above preparation method improves the density and uniformity of organic ceramic materials through the mutual cooperation of specific components with specific ratios, compensates for the influence of color powder on mechanical properties, and obtains unexpected effects.

[0026] Understandably, the color powder includes but is not limited to plastic color powder.

[0027] As an example, the mass ratio of polyphenylene sulfide, zirconia, coupling agent and color powder can be 1:1:0.01:0.05, 1:1.5:0.01:0.05, 1:2.0:0.01:0.05, 1:7 / 3:0.01:0.048,

[0028] 1:2.5:0.01:0.05, 1:3.0:0.01:0.05, 1:3.5:0.01:0.05, 1:4.0:0.01:0.05 and 1:4:0.05:0.04, or it can also be within the range formed by any two of the above point values as the end values.

[0029] The mass ratio of polyphenylene sulfide, zirconia, coupling agent and color powder is preferably 1:1.5 - 3:0.01 - 0.02:0.03 - 0.048. Under this mass ratio, the compatibility between raw material components is better, further improving the gloss and mechanical properties of the organic ceramic.

[0030] As an example, the average particle size of zirconia can be 0.5 µm, 0.6 µm, 0.7 µm, 0.8 µm, 0.9 µm, 1.0 µm, 1.1 µm, 1.2 µm, 1.3 µm, 1.4 µm, 1.5 µm, 1.6 µm, 1.7 µm, 1.8 µm, 1.9 µm, 2.0 µm, 2.1 µm, 2.2 µm, 2.3 µm, 2.4 µm, 2.5 µm, 2.6 µm, 2.7 µm, 2.8 µm, 2.9 µm and 3.0 µm, or can also be within the range formed by any two of the above point values as the end values.

[0031] The average particle size of zirconia is preferably 0.5 µm - 1 µm. Within this particle size range, zirconia can take into account the gloss, mechanical properties, heat resistance and electrical properties of the organic ceramic material, and the prepared organic ceramic has better comprehensive properties.

[0032] In some of the embodiments, before the internal mixing and injection molding, the following steps are further included: grinding polyphenylene sulfide and zirconia in a solvent to form a slurry, then adding a coupling agent and color powder to the slurry, grinding and drying to obtain the organic ceramic powder. The solvent includes but is not limited to alcohol.

[0033] In some of the embodiments, the molecular weight of the polyphenylene sulfide is 4000 - 5000.

[0034] In some of the embodiments, the melt index of the polyphenylene sulfide is 6 g / 10 min - 10 g / 10 min.

[0035] In some of the embodiments, the coupling agent includes at least one of γ-aminopropyltriethoxysilane, γ-(2,3-epoxypropoxy)propyltrimethoxysilane, and vinyltriethoxysilane.

[0036] In some of the embodiments, the color powder includes at least one of titanium dioxide, iron oxide red, iron oxide yellow, cobalt blue, bismuth yellow, titanium nickel yellow and cerium red.

[0037] In some of the embodiments, the mixing is first grinding polyphenylene sulfide and zirconia in a solvent for 48 h - 60 h, and then adding a coupling agent and color powder and grinding for 6 h - 10 h.

[0038] In some of the embodiments, the internal mixing temperature of the internal mixing and injection molding is 300 °C - 400 °C.

[0039] The kneading temperature is preferably 300°C to 350°C. When kneading at this temperature, polyphenylene sulfide has good fluidity and can be fully mixed with zirconia, coupling agent, and color powder, avoiding the agglomeration of zirconia.

[0040] In some of the embodiments, the heat treatment temperature is 180°C to 250°C.

[0041] The heat treatment temperature is preferably 180°C to 200°C. Conducting heat treatment at this temperature can eliminate the internal stress of the organic ceramic, promote the interfacial bonding between raw material components, and optimize the comprehensive properties of the organic ceramic.

[0042] In some of the embodiments, the kneading temperature for kneading and injection molding is 300°C to 350°C, and the heat treatment temperature is 180°C to 200°C.

[0043] In some of the embodiments, the heat treatment time is 2h to 4h.

[0044] In some of the embodiments, it further includes a polishing treatment step. The polishing treatment sequentially includes rough polishing treatment, fine polishing treatment, and finish polishing treatment. The rough polishing treatment uses a polyurethane polishing pad and silica polishing liquid for surface polishing.

[0045] In some of the embodiments, the fine polishing treatment uses a wire wheel and white wax for polishing.

[0046] In some of the embodiments, the finish polishing treatment uses a cloth wheel and red wax for polishing.

[0047] In some of the embodiments, the rough polishing treatment uses a polyurethane polishing pad and silica polishing liquid for surface polishing. The polishing time is 60 min to 90 min, and the polishing rotation speed is 40 revolutions per minute to 50 revolutions per minute.

[0048] In some of the embodiments, the fine polishing treatment uses a wire wheel and white wax for polishing. The polishing time is 10 min to 20 min, and the polishing rotation speed is 2600 revolutions per minute to 2800 revolutions per minute.

[0049] In some of the embodiments, the finish polishing treatment uses a cloth wheel and red wax for polishing. The polishing time is 60 min to 70 min, and the polishing rotation speed is 2000 revolutions per minute to 2400 revolutions per minute.

[0050] In some of these embodiments, the polishing process sequentially includes rough polishing, fine polishing, and finish polishing. For rough polishing, a polyurethane polishing pad and silica polishing liquid are used for surface polishing. For fine polishing, a wire wheel and white wax are used for polishing. For finish polishing, a cloth wheel and red wax are used for polishing. This polishing method removes the oxides on the surface of the organic ceramic blank and performs surface polishing through rough polishing, making the appearance surface free of scratches, pits, or orange peel, etc. Through fine polishing, the oxides on the surface of the organic ceramic blank are further removed and surface polishing is further carried out, making the appearance surface free of scratches, pits, or particulate matter, etc.; through finish polishing, the organic ceramic is polished to remove the surface white mist, further improving the gloss and smoothness of the surface of the organic ceramic, and making the surface of the organic ceramic reach a flat and bright mirror effect.

[0051] White wax is rougher than red wax. Using white wax and red wax in combination for fine polishing, white wax is beneficial for removing surface unevenness, and red wax is beneficial for surface polishing. The two cooperate with each other and synergistically enhance the effect, greatly improving the gloss of the organic ceramic material.

[0052] In some of these embodiments, the polishing process sequentially includes rough polishing, fine polishing, and finish polishing; for rough polishing, a polyurethane polishing pad and silica polishing liquid are used for surface polishing, and the polishing speed is 40 rpm to 50 rpm; for fine polishing, a wire wheel and white wax are used for polishing, and the polishing speed is 2600 rpm to 2800 rpm; for finish polishing, a cloth wheel and red wax are used for polishing, and the polishing speed is 2000 rpm to 2400 rpm.

[0053] In the second aspect of the present application, an organic ceramic material is provided, which is prepared by using the preparation method of the organic ceramic material described in the first aspect.

[0054] The organic ceramic material includes, but is not limited to, decorative materials.

[0055] In the third aspect of the present application, an organic ceramic product is provided, which includes the organic ceramic material described in the second aspect.
