Description

Technical Field

[0001] The invention relates to the technical field of resin clay, in particular to a temperature-variable resin clay. Background Art

[0002] Resin clay is a material used to make various handicrafts and decorations. It has the characteristics of strong plasticity, fast drying speed and rich colors.

[0003] The prior art includes simulated flowers, simulated succulents, miniature flowers, fruits and vegetables, cute dolls and other simulated products made of resin clay. These products strive to be highly similar to animals and plants in nature in appearance, but animals and plants in nature will also change color due to changes in ambient temperature. However, most of the current resin clay products cannot achieve this temperature-induced color change effect, resulting in certain limitations in their simulation. For this reason, we propose a temperature-changing resin clay. Summary of the invention

[0004] The purpose of the present invention is to solve the problem of artificial flowers, artificial succulents and other artificial products made of resin clay in the prior art. These products strive to be highly similar to animals and plants in nature in appearance, but animals and plants in nature will also change color due to changes in ambient temperature. However, most of the current resin clay products cannot achieve this temperature-induced color change effect, resulting in certain limitations in their degree of simulation. The present invention provides a temperature-changing resin clay.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] Thermostatic resin clay comprises the following raw materials in percentage by weight: 50%-65% ethylene vinyl acetate copolymer (EVA), 25%-35% starch, 4%-6% glycerol, 4%-6% color-changing pigment, 0.3%-0.7% sodium benzoate and 2%-5% liquid paraffin.

[0007] Furthermore, the temperature-changing resin clay comprises the following raw materials in percentage by weight: 50% ethylene vinyl acetate copolymer (EVA), 35% starch, 4% glycerol, 6% color-changing pigment, 0.3% sodium benzoate, and 4.7% liquid paraffin.

[0010] Furthermore, the temperature-variable resin clay is also added with 0.2%-0.4% by weight of fragrance.

[0011] Furthermore, the temperature-dependent resin clay is also added with 5%-10% by weight of water.

[0012] Furthermore, the starch includes one or more of corn starch, potato starch, tapioca starch, wheat starch and rice starch.

[0013] Furthermore, the color-changing pigment is one or more of a thermosensitive pigment and a photochromic pigment.

[0014] A method for processing temperature-dependent resin clay comprises the following steps:

[0015] S1. Weigh the raw materials according to the weight percentage of ethylene vinyl acetate copolymer (EVA) 50%-65%, starch 25%-35%, glycerol 4%-6%, color-changing pigment 4%-6%, and sodium benzoate 0.3%-0.7%, pour them into a blender, and stir at a low speed until they are evenly mixed;

[0016] S2. Slowly add water and continue stirring for 30-60 minutes until the mixture becomes a muddy state;

[0017] S3. Add liquid paraffin and continue stirring for about 20-30 minutes until the clay is soft and has a moderate texture.

[0018] Furthermore, the stirrer is a twin-screw mixer.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. EVA in the present invention has good flexibility, weather resistance and plasticity, and is the main base material of resin clay. The color-changing pigment can change color according to temperature changes or light changes, thereby increasing the realism and interactivity of the product. By adding the color-changing pigment, the resin clay product can present color changes similar to those of animals and plants in nature at different ambient temperatures, thereby improving the simulation and enhancing the ornamental and interesting nature of the product.

[0021] 2. The starch in the present invention provides good plasticity and a certain bonding force, which is helpful to form a fine texture. Glycerol, as a moisturizer, can maintain the softness and moisture of the clay and prevent it from drying and cracking. It has good flexibility and plasticity, which is convenient for users to perform various shapes and creations. Sodium benzoate, as a preservative, is used to extend the service life of the product and prevent mold growth.

[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Embodiment 1:

[0025] The invention provides a temperature-changing resin clay, which comprises the following raw materials in percentage by weight: 50%-65% of ethylene vinyl acetate copolymer (EVA), 25%-35% of starch, 4%-6% of glycerol, 4%-6% of color-changing pigment, 0.3%-0.7% of sodium benzoate and 2%-5% of liquid paraffin.

[0026] EVA has good flexibility, weather resistance and plasticity, and is the main base material of resin clay. Starch provides good plasticity and a certain degree of adhesion, which helps to form a delicate texture. Glycerol, as a humectant, can maintain the softness and moisture of the clay and prevent drying and cracking. Color-changing pigments can change color according to temperature changes or light changes, increasing the realism and interactivity of the product. Sodium benzoate is used as a preservative to extend the service life of the product and prevent mold growth. Liquid paraffin, as a lubricant, improves the operability of the clay and the gloss of the finished product. By adding color-changing pigments, resin clay products can show color changes similar to those of animals and plants in nature at different ambient temperatures, thereby improving the simulation and enhancing the product's ornamental and interesting properties.

[0027] In this embodiment, preferably, the temperature-variable resin clay is further added with 0.2%-0.4% by weight of spices. The spices are selected according to the type of the finished product to enhance the sensory experience of the product.

[0028] In this embodiment, preferably, the temperature-variable resin clay is further added with 5%-10% water by weight. Adding water can adjust the consistency and plasticity of the clay, and gradually dripping it during the production process keeps the clay soft and plastic but not sticky, which is convenient for subsequent plastic use.

[0029] In this embodiment, preferably, the starch includes one or more of corn starch, potato starch, tapioca starch, wheat starch and rice starch.

[0030] Cornstarch: Due to its wide availability and relatively low cost, cornstarch is one of the most commonly used starches in resin clay. It has good viscosity and water absorption properties and blends well with other ingredients to form a homogenous mixture.

[0031] Potato starch: Potato starch has a finer texture than corn starch, so it gives the resin clay a smoother and softer feel. It also has better water absorption, which helps to keep the clay moist and soft.

[0032] Tapioca Starch: Although it has a slightly coarse texture, tapioca starch's high viscosity makes it ideal for use in resin clay. It adds strength and stability to the clay, making the finished product more durable.

[0033] Wheat starch: Wheat starch contains a certain amount of gluten protein, which makes it have a certain elasticity in resin clay. However, too much gluten protein may affect the plasticity and softness of the clay, so it needs to be used in moderation.

[0034] Rice starch: Rice starch has good water absorption and stability, which can maintain the moisture and shape of resin clay. It can also increase the fineness and glossiness of the clay, making the finished product more beautiful.

[0035] When choosing the type of starch, you need to consider the specific use and desired characteristics of the resin clay. For example, if you want the clay to have higher strength and stability, you can choose tapioca starch or wheat starch; if you want the clay to be softer and finer, you can choose potato starch or rice starch. At the same time, you also need to pay attention to the compatibility of starch with other ingredients to ensure the overall performance and quality of the resin clay.

[0036] In this embodiment, preferably, the color-changing pigment is one or more of a thermosensitive pigment and a photosensitive color-changing pigment.

[0037] Thermosensitive pigments can change color with temperature, such as SW 1220 pink-to-colorless pigment powder, WS0066 colorless-to-black pigment powder, SW 3080 golden-to-colorless pigment powder, WS6020 colorless-to-purple pigment powder, etc. produced by Shanghai Jingyan Chemical Co., Ltd.;

[0038] Photochromic pigments can change color according to changes in light. For example, the Ranbar DP4010 colorless green dye, the Ranbar GS6020 photosensitive colorless purple color-changing pigment, and the Ranbar GS3080 colorless yellow photochromic pigment produced by Shanghai Jingyan Chemical Co., Ltd. can change color according to changes in light.

[0039] Thermosensitive pigments and photochromic pigments can be used together to simulate the color changes of flowers and succulents in natural environments as temperature and light change, making the simulation model more realistic.

[0040] The beneficial effects of the present invention are as follows:

[0041] 1. By using color-changing pigments, resin clay can show rich color changes under different temperatures or lighting conditions, thereby improving the ornamental and interactive nature of the product.

[0042] 2. The temperature-changing resin clay of the present invention has good flexibility and plasticity, which is convenient for users to carry out various shapes and creations. At the same time, it has certain weather resistance and is suitable for long-term storage.

[0043] 3. By adding starch and glycerol, the resin clay of the present invention has good moisture retention and adhesion, can maintain the softness and moisture of the clay, and prevent drying and cracking.

[0044] 4. The temperature-variable resin clay of the present invention also has certain antibacterial properties, because sodium benzoate is added as a preservative, which can effectively prevent mold growth and extend the service life of the product.

[0045] 5. By selecting different types of starch and color-changing pigments, the temperature-changing resin clay of the present invention can be customized according to different needs to meet the requirements of different users for product characteristics.

[0046] See also Figure 1 , a method for processing temperature-dependent resin clay, comprising the following steps:

[0047] S1. Weigh the raw materials according to the weight percentage of ethylene vinyl acetate copolymer (EVA) 50%-65%, starch 25%-35%, glycerol 4%-6%, color-changing pigment 4%-6%, and sodium benzoate 0.3%-0.7%, pour them into a blender, and stir at a low speed until they are evenly mixed;

[0048] S2. Slowly add water and continue stirring for 30-60 minutes until the mixture becomes a muddy state;

[0049] S3. Add liquid paraffin and continue stirring for about 20-30 minutes until the clay is soft and has a moderate texture.

[0050] When S2 and S3 are stirred and mixed, water and liquid paraffin are added in small amounts for multiple times. After each addition, the operator takes samples at intervals and feels the texture of the resin clay with his hands, thereby adjusting the amount of water and liquid paraffin to be added next time according to the feel.

[0051] In this embodiment, preferably, the stirrer is a twin-screw mixer. Model SHM-500, produced by Jinyuan Machinery Co., Ltd., has the characteristics of high efficiency and uniform mixing. The two propellers of the twin-screw mixer rotate in opposite directions, which can effectively mix the raw materials evenly, while avoiding excessive heat generated by the raw materials during the mixing process, thereby ensuring the quality of the mixture.
