[0002] In the field of automotive technology, drivers and passengers have a need for heating in the car cabin, which is usually achieved by air conditioning, and some are achieved by heating direct contact parts. For example, in cold weather, heated seats can quickly increase the temperature of the seat surface, providing drivers and passengers with a warm and comfortable riding experience; especially for people who drive or ride for a long time, heated seats can relieve the discomfort caused by the cold and reduce muscle tension.

[0003] In addition, in order to make the car cabin warmer in cold winter and improve the experience and comfort of the drivers and passengers, heating functions can be added to the parts around the passengers. For example, heating can be added to some areas of the door interior panels, including but not limited to the upper part of the door panel, the armrest, the sub-panel armrest, the rear seat middle armrest, and the steering wheel. This can provide a warm touch when opening and closing the door or leaning on the door.

[0043] One embodiment of the present invention provides a paint product, including a substrate and a coarse ash layer, a fine ash layer, a clear ash layer, a color paint layer, a decorative layer and a transparent paint layer sequentially stacked on the substrate.

[0044] The coating of the coarse ash layer includes coarse tile ash and raw lacquer, and the particle size of the coarse tile ash is 40-100 mesh. The coating of the fine ash layer includes the first fine tile ash, raw lacquer and conductive and thermally conductive material, and the particle size of the first fine tile ash is 100-180 mesh.

The conductive and thermally conductive materials in the fine ash layer and the clean ash layer independently include one or more of graphite powder, graphene and carbon nanotubes.

[0045] The above-mentioned paint products improve the ash layer on the substrate, specifically using specific coatings to form a coarse ash layer, a fine ash layer and a clean ash layer that are stacked in sequence, and the particle size of the tile ash in the coarse ash layer, the fine ash layer and the clean ash layer is gradually reduced, so that the surface can be better smoothed, and the cracks in the ash layer and other undesirable effects can be avoided, and the adhesion of the subsequent paint layer can be guaranteed; by using a specific mesh of tile ash and conductive and thermal conductive materials in the fine ash layer and the clean ash layer, its thermal conductivity, heat resistance, cold resistance and other environmental resistance can be improved, and at the same time, the color paint layer, decorative layer and transparent paint layer that are stacked in sequence give the lacquer an aesthetic appearance. Lacquer is an intangible cultural heritage, and the application of the lacquer products using lacquer on automobiles gives it a profound cultural value and artistic charm.

[0046] The above-mentioned paint products have good environmental resistance, especially fast heating temperature rise performance, and can be used to meet but not limited to the heating needs of parts of the car door interior panels such as the upper part of the car door panel, armrests, as well as the sub-panel armrests, rear seat middle armrests, steering wheels and other areas, thus having both beautiful and practical characteristics.

[0047] As an example, the particle size of the coarse tile ash can be 40 mesh, 45 mesh, 50 mesh, 60 mesh, 80 mesh, 100 mesh, or within the range formed by any two of the above point values ​​as end values. The particle size of the first fine tile ash can be 100 mesh, 120 mesh, 140 mesh, 160 mesh, 170 mesh, 180 mesh, or within the range formed by any two of the above point values ​​as end values. The particle size of the first fine tile ash can be 200 mesh, 230 mesh, 240 mesh, or within the range formed by any two of the above point values ​​as end values.

[0048] In some of the embodiments, in the coating of the coarse ash layer, the weight ratio of coarse tile ash and raw lacquer is (1~2):1. As an example, it can be 1:1, 1:1.5, 2:1, or within the range consisting of any two of the above point values ​​as end values, and the same is true below.

[0049] Furthermore, the coarse ash layer and its coating may or may not include conductive and thermally conductive materials. Since the coarse ash layer is adjacent to or in direct contact with the substrate, the conductive and thermally conductive materials are arranged in the coarse ash layer, which will cause the substrate to absorb a large amount of heat, thereby affecting the heating performance of the paint product. Preferably, the coarse ash layer and its coating do not include conductive and thermally conductive materials. Furthermore, the composition of the coarse ash layer consists of coarse tile ash and raw lacquer.

[0050] In some of the embodiments, in the coating of the fine ash layer, the weight ratio of the first fine ash, raw lacquer and the conductive and thermally conductive material is (1-2):1:(0.1-0.5). As an example, in the coating of the fine ash layer, the weight ratio of the first fine ash, raw lacquer and the conductive and thermally conductive material may be 1:1:0.1, 1:1:0.2, 1:1:0.3, 1:1:0.4, 1:1:0.5, 1.5:1:0.1, 1.5:1:0.2, 1.5:1:0.3, 1.5:1:0.4, 1.5:1:0.5, 2:1:0.1, 2:1:0.2, 2:1:0.3, 2:1:0.4, 2:1:0.5, or within the range formed by any two of the above point values ​​as end values, and the following is similar.

[0051] Furthermore, in the coating of the fine ash layer, the weight ratio of the first fine tile ash, the raw lacquer and the conductive and thermally conductive material can be 2:1:(0.1-0.5), or (1-2):1:(0.2-0.4), or 2:1:(0.2-0.4). Within this range, the prepared paint product has a faster heating temperature rise performance on the basis of taking into account good environmental resistance such as heat resistance, cold resistance and resistance to alternating cold and heat.

[0052] In some of the embodiments, in the coating of the cleaning layer, the weight ratio of the second fine tile ash, raw lacquer and the conductive and thermally conductive material is (1-2):1:(0.1-0.5).

[0053] Furthermore, in the coating of the dust removal layer, the weight ratio of the second fine tile ash, raw lacquer and the conductive and thermal conductive material can be 2:1:(0.1-0.5), or (1-2):1:(0.2-0.4), or 2:1:(0.2-0.4). Within this range, the prepared paint product has a faster heating temperature rise performance on the basis of taking into account good environmental resistance such as heat resistance, cold resistance and resistance to alternating cold and heat.

[0054] In some embodiments, the particle size of the graphite powder is 200 mesh to 240 mesh, for example, 200 mesh, 230 mesh, 240 mesh, or within a range consisting of any two of the above point values ​​as end values.

[0055] In some of the embodiments, the diameter of the graphene sheet is 1 μm to 20 μm, for example, it can be 1 μm, 2 μm, 5 μm, 10 μm, 12 μm, 15 μm, 18 μm, 20 μm, or within the range formed by any two of the above point values ​​as end values.

[0056] In some embodiments, the diameter of the carbon nanotube is 5 nm to 30 nm, and the length is 5 μm to 200 μm. As an example, the diameter of the carbon nanotube is 10 nm, and the length is 100 μm.

[0057] Furthermore, the conductive and thermally conductive material in the fine ash layer and the clean ash layer preferably includes graphene. Compared with other conductive and thermally conductive materials, the paint product made of conductive and thermally conductive materials including graphene has faster heating and temperature rise performance on the basis of good environmental resistance such as heat resistance, cold resistance and resistance to alternating cold and heat.

[0058] In some embodiments, the coatings of the coarse ash layer, the fine ash layer, and the clean ash layer each independently include a solvent, and the solvent is water or kerosene. Adding water can adjust the consistency of the paint-ash mixture for better application and operation; it can also control the drying speed; adding kerosene can prevent sticking, make the scraping smoother, and make the surface smoother, and it can also control the drying speed.

[0059] Furthermore, the weight ratio of the solvent in the coating of the coarse ash layer, fine ash layer and clear ash layer to the raw lacquer in the corresponding coating is (0.1~0.5):1. As an example, it can be 0.1:1, 0.2:1, 0.3:1, 0.4:1, 0.5:1, or within the range consisting of any two of the above point values ​​as end values.

[0060] In some of the embodiments, the thickness of the coarse ash layer is 0.2 mm to 0.6 mm. As an example, it can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, or within a range consisting of any two of the above point values ​​as end values.

[0061] In some of the embodiments, the thickness of the fine ash layer is 0.1 mm to 0.5 mm. As an example, it can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, or within a range consisting of any two of the above point values ​​as end values.

[0062] In some of the embodiments, the thickness of the cleaning layer is 0.1 mm to 0.3 mm. As an example, it can be 0.1 mm, 0.2 mm, 0.3 mm, or within a range consisting of any two of the above point values ​​as end values.

[0063] In some of the embodiments, the thickness of the paint layer is 10 μm to 50 μm. For example, it can be 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, or within a range consisting of any two of the above point values ​​as end values.

[0064] In some embodiments, the thickness of the decoration layer depends on the decoration material and technique, and may be from a few micrometers to several hundred micrometers, for example, 5 μm to 500 μm.

[0065] In some embodiments, the decorative layer is formed by one or more of painting, gilding, gold halos, gold and silver painting and inlaying. As an example, the decorative layer is formed by painting and gilding.

[0066] In some of the embodiments, the thickness of the transparent paint layer is 100 μm to 500 μm. For example, it may be 100 μm, 200 μm, 300 μm, 400 μm, 500 μm, or a range consisting of any two of the above point values ​​as end values.

[0067] In some embodiments, the material of the substrate includes one or more of a metal material and an alloy material. In addition to including one or more of a metal material and an alloy material, the material of the substrate may also include materials such as plastic, for example, a plastic layer is laminated on a metal material or an alloy material.

[0068] Furthermore, the paint products made of the substrate are used in many places inside the car, such as door panels, sub-panel armrests, rear seat center armrests, steering wheels, etc.

[0069] Another aspect of the present application provides a method for preparing a paint product, the paint product being any of the paint products described above, and the preparation method comprising the following steps S10 to S40.

[0070] S10, applying a coarse ash layer coating on the substrate to form a coarse ash layer.

[0071] In some embodiments, before step S10, a step of grinding the substrate is also included, which can be done manually, mechanically, or in combination. Multiple passes of grinding can be used, with sandpaper being used from coarse to fine. As an example, coarse sandpaper can be selected as #80 and above, and fine sandpaper can be selected as #400 and above. In this way, the bonding force of the coarse ash layer on the surface of the substrate is improved, and its environmental resistance such as heat resistance and cold resistance can be improved.

[0072] In some embodiments, because it is used for interior decoration, in order to prevent the size deformation of the parts under various working conditions, the substrate is a metal alloy substrate or a metal material substrate.

[0105] 5. Apply transparent paint and polish. Apply the diluted raw paint evenly or spray it on the surface of the decorative layer. After applying or spraying, dry it in a cool place. After drying, polish it. Repeat this process twice to form a transparent paint layer with a thickness of 300μm.

[0106] Comparative Example 1:

[0107] Comparative Example 1 is substantially the same as Example 2, except that graphene is omitted from both the fine ash coating and the clean ash coating in step 2 of Comparative Example 1. The specific steps are as follows:

[0108] 1. Select zinc alloy as the substrate, mechanically polish the main surface of the substrate, and manually polish the edges. It can be polished multiple times, with sandpaper from coarse to fine. Choose #80 (# represents the mesh number) for coarse sandpaper and #400 for fine sandpaper.

[0109] 2. Apply ash. On the polished substrate, apply coarse ash paint, fine ash paint, and clear ash paint in sequence to form a coarse ash layer, a fine ash layer, and a clear ash layer that are stacked.

[0110] After each layer is scraped and applied, let it dry in a cool place. After drying, sand it with #400 sandpaper.

[0111] The coarse ash paint is made by mixing coarse tile ash and raw lacquer in a weight ratio of 2:1, and adding kerosene in a mass ratio of 0.2:1; the particle size of the coarse tile ash is 80 mesh.

[0112] The fine ash paint is prepared by mixing the first fine ash and raw lacquer in a weight ratio of 2:1, and adding kerosene in a weight ratio of 0.2:1; the particle size of the first fine ash is 160 meshes.

[0113] The cleaning paint is made of second fine tile ash and raw lacquer in a weight ratio of 2:1, and kerosene is added in a mass ratio of 0.2:1, and the particle size of the second fine tile ash is 200 mesh.

[0114] 3. Apply primer (color paint). Apply the prepared color paint by brushing or spraying on the surface after plastering as the base color of the decoration. After brushing or spraying, dry it in a cool place to form a color paint layer.

[0115] 4. Decoration. Use painting and gilding to form a decorative layer

[0116] 5. Apply transparent lacquer and polish. Apply the diluted raw lacquer evenly on the surface of the decorative layer by brushing or spraying. After brushing or spraying, dry it in a cool place. After drying, polish it. Repeat the process twice to form a transparent lacquer layer. You will get the lacquerware decorative piece.

[0117] Comparative Example 2:

[0118] Comparative Example 2 is substantially the same as Example 2, except that the step of scraping and coating the clearing paint is omitted in step 2 of Comparative Example 2. After scraping and coating the fine ash paint to form a fine ash layer, the process of applying the primer (color paint) in step 3 is directly performed.

[0119] Comparative Example 3:

[0120] Comparative Example 3 is basically the same as Example 2, except that the types of tile ash in the fine ash paint and the cleaning paint in Comparative Example 3 are interchanged, as shown in Table 1.

[0121] Example 3

[0122] Example 3 is basically the same as Example 2, except that the amount of graphene added to the fine ash paint and the cleaning paint in step 2 of Example 3 is different. Specifically, the weight ratios of tile ash, raw lacquer and graphene in the fine ash paint and the cleaning paint are both 2:1:0.1.

[0123] Example 4

[0124] Example 4 is basically the same as Example 2, except that the amount of graphene added to the fine ash paint and the cleaning paint in step 2 of Example 4 is different. Specifically, the weight ratios of tile ash, raw lacquer and graphene in the fine ash paint and the cleaning paint are both 2:1:0.3.

[0125] Example 5

[0126] Example 5 is basically the same as Example 2, except that the graphene in the fine ash paint and the cleaning paint in step 2 of Example 5 is replaced with an equal mass of graphite powder.

[0127] Example 6

[0128] Example 6 is basically the same as Example 2, except that the graphene in the fine ash paint and the cleaning paint in step 2 of Example 5 are replaced with an equal mass of carbon nanotubes.

[0129] Example 7

[0130] Example 7 is basically the same as Example 3, except that graphene is also added to the coarse ash paint in Example 7, and the coarse ash paint is a mixture of coarse tile ash, raw lacquer and graphene in a weight ratio of 2:1:0.5; the particle size of the coarse tile ash is 80 mesh.

[0131] The following is a performance test.

[0132] 1. Heat resistance: Place the lacquerware decorative parts in a 90℃ test box for 72 hours and observe the condition of the samples after the test.

[0133] 2. Cold resistance: Place the lacquerware decorative pieces in a -40℃ test chamber for 72 hours and observe the condition of the samples after the test.

[0134] 3. Resistance to alternating cold and hot conditions: The test conditions are three cycles, and the test conditions for each cycle are:

[0135] First, store in a (-30±2)℃ test chamber for 2 hours, then store in a (23±2)℃ test chamber for 0.5 hours, then store in an 80℃ test chamber for 2 hours, then store in a (23±2)℃ test chamber for 0.5 hours, then store in a (50±2)℃ and 95%RH test chamber for 0.5 hours, and then store in a (23±2)℃ test chamber for 0.5 hours. Observe the state of the sample after the test.

[0136] 4. Heating performance: Pre-store the lacquerware decorative parts in a 0℃ test box for 8 hours, apply a test voltage of 13V for 5 minutes, and then measure the heating temperature of the sample surface (the surface of the transparent paint layer).

[0137] Some parameters and performance test results of various embodiments and comparative examples are shown in Tables 1 and 2.

[0138] Table 1

[0139]

[0140] Table 2

[0141]

[0142] As can be seen from Table 1 and Table 2, in Comparative Example 1, no conductive and thermal conductive material is provided in the fine ash paint and the cleaning paint, and the heating temperature rise performance is poor. In Comparative Example 2, the cleaning layer formed by the cleaning paint is omitted, and the environmental resistance performances such as heat resistance, cold resistance, and resistance to alternating cold and heat are poor. The paint products prepared in each embodiment have good environmental resistance performances such as heat resistance, cold resistance, and resistance to alternating cold and heat, especially faster heating temperature rise performance.
