Description

Technical Field

[0001] The present invention relates to the technical field of sculpture, in particular to sculpture oil clay and a preparation method thereof. Background Art

[0002] Industrial clay, also known as fine carving clay, is one of the most commonly used materials for industrial modeling. Its main component is an oily mixture of various industrial waxes, oils, and fillers. Industrial clay is widely used in the production of physical models during the design development phase of industrial products such as small cars, motorcycles, and household appliances. Different proportions of clay are used to verify and correct the visual effects of design renderings in real-world situations. Compared to other modeling materials, clay models are highly malleable and can be repeatedly filled, scraped, and modified to modify the product's shape. The refined model's surface is dense and smooth, making it easy for modelers to apply decorative techniques such as film application and painting to achieve the optimal visual effect of the design.

[0003] Currently, the most commonly used industrial clays are 8433 lightweight sulfur-free industrial clay and NS60 sulfur-free industrial clay. These two imported clays have long been recognized by many modelers at major OEMs and design companies due to their excellent material properties (hardness of approximately 80HC at room temperature and 20HC after baking at 60°C). Domestic industrial clays often have drawbacks such as mild toxicity (due to the addition of substances such as sulfur and tung oil), high shrinkage, insufficient toughness, and a rough texture.

[0004] In view of this, it is necessary to provide a new sculpture oil clay and a preparation method thereof to address the above-mentioned shortcomings. Summary of the Invention

[0097] Performance testing:

[0098] Test objects: sludge samples of Experimental Examples 1-13 and Comparative Examples 1-8.

[0099] Test method:

[0100] The hardness of the test object is tested using a Shore C durometer at room temperature (21°C-25°C);

[0101] Temperature resistance is determined by baking the test object at 60°C for 12 hours and then immediately testing the hardness using a Shore C durometer.

[0102] The test results are shown in Table 1.

[0103] Table 1

[0104]

[0105]

[0106] Note: A means average toughness, AA means good toughness, and AAA means very good toughness.

[0107] As shown in Table 1, compared with Comparative Examples 1-8, the industrial paraffin wax, PE wax and calcium carbonate filler used in the present invention can all improve the hardness of the sculpture oil mud, but the sculpture oil mud with high hardness cannot meet the toughness requirement. Compared with industrial paraffin wax, PE wax has a greater impact on the temperature resistance of the sculpture oil mud. The synergistic effect of the raw materials of the sculpture oil mud formula in the present invention can not only meet the hardness requirement but also meet the toughness requirement.

[0108] In order to further illustrate the effect of the melting point of industrial paraffin on the performance of sludge, the industrial paraffin provided in Experimental Example 1 was selected with melting points of 50°C, 60°C, 70°C, 80°C and 85°C as the raw materials of Experimental Example 1 to verify the effect of different melting points on the hardness of sludge and the recovery rate of hardness at room temperature. The test results are as follows: Figure 1 As shown, Figure 1 50# industrial paraffin means industrial paraffin with a melting point of 50℃, 60# industrial paraffin means industrial paraffin with a melting point of 60℃, 70# industrial paraffin means industrial paraffin with a melting point of 70℃, 80# industrial paraffin means industrial paraffin with a melting point of 80℃, and 85# industrial paraffin means industrial paraffin with a melting point of 85℃.

[0109] Depend on Figure 1It can be seen that the melting point of industrial paraffin affects the hardness of sculpture oil clay and the rate of hardness recovery at room temperature. As the melting point of industrial paraffin increases, the hardness of sculpture oil clay increases, and the rate of hardness recovery at room temperature is faster.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
