Description

Technical Field

[0001] The invention relates to the technical field of color processing of silicone products, and in particular to a color gradient transition process on silicone products. Background Art

[0002] At present, the process of silicone vulcanization molding is quite mature, and there are many types of silicone products. Silicone raw materials can be used to realize products with different structures through compression molding. However, silicone products in the prior art are generally formed by molding single-color materials, molding by the lower KT method, or molding multi-color products by transferring materials and oil pressure. The multi-color silicone products made by the above methods have distinct colors, and products with distinct colors are easy to cause visual fatigue.

[0003] In addition, in order to achieve products with different colors but not distinct colors, the existing technology currently adopts a spraying method. However, the silicone products with different colors produced by the spraying method of the existing technology can only meet the requirements of the appearance surface, and cannot be achieved inside the non-appearance surface. Moreover, the silicone products with different colors produced by the spraying method are easily affected by external factors such as friction and fall off, and the stability is poor, which in turn affects the appearance of the product. A color gradient transition process on the silicone product is needed to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to provide a color gradient transition process on a silicone product to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a color gradient transition process on a silicone product, comprising the following steps:

[0006] S1. First, to make the silicone raw material into a single color, material preparation is required. First, prepare the necessary materials such as silicone raw material, silicone masterbatch and vulcanizer;

[0007] S2. Next, color matching: according to the required color, add the silicone masterbatch to the silicone raw material in a certain proportion, add additives to prevent discoloration caused by oxidation, and use a stirrer to fully stir evenly to ensure that the masterbatch is completely integrated into the silicone raw material;

[0008] S3. Select a suitable mold, ensure that the inside of the mold is clean and free of impurities, pour the prepared silicone raw materials into the mold, pay attention to control the amount of raw materials, and ensure uniform filling;

[0009] S4, placing the mold into a hot pressing machine, and setting the required temperature, pressure and time parameters;

[0010] S5. After the silicone raw material is completely solidified, the molded silicone product is taken out of the mold using an air spray or other tool to obtain the silicone raw material, and then masterbatches of different colors are added thereto;

[0011] S6. Twist the silicone product in your hand like twisting a twist, so that the colors are evenly superimposed together to form a variety of gradient color effects;

[0012] S7. Put the mixed silicone into a hydraulic machine for molding. During the high-pressure extrusion process, the masterbatch flows in the silicone product, forming a gradient of colorful colors.

[0013] As a preferred technical solution of the present invention, the materials in the material preparation in step S1 must ensure that all materials are clean and free of impurities, and materials with impurities and defects are sorted out.

[0014] As a preferred technical solution of the present invention, the addition ratio of the color blending silica gel masterbatch in step S2 is 0.2%, wherein the auxiliary agent is an antioxidant, and stirring needs to be fully mixed to ensure that the various ingredients are evenly distributed, thereby reducing the color difference problem caused by uneven mixing of raw materials.

[0015] As a preferred technical solution of the present invention, the selection of the mold in step S3 can be based on needs, and a layer of release agent can be coated inside the mold to facilitate subsequent demoulding.

[0016] As a preferred technical solution of the present invention, in step S5, the product can be trimmed and subjected to secondary sulfur treatment as required, and the obtained silicone raw material needs to be quality checked to ensure uniform color, smooth surface, and no bubbles or defects.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The present invention is a color gradient transition process on a silicone product. An antioxidant is added to the silicone product during the mixing process of the color gradient process. The antioxidant can extend the service life of the silicone product and can effectively prevent the silicone product from changing color due to oxidation. Before the raw material is placed in the mold, a layer of release agent is applied to the inside of the mold to facilitate subsequent demolding and prevent sticking, which in turn affects subsequent demolding.
