Problems solved by technology

[0003] The appearance of products with partial frosting effect is more cool and comfortable to wear. Therefore, when rubber materials are used to manufacture some wearable products, not only the rubber materials must have good mechanical properties, but also new requirements for the appearance of molded products. It is required to have a matte effect and feel smoother, but the wearable products made of rubber materials in the traditional technology do not meet the above requirements. In the traditional technology, in order to achieve the matte effect, after the product is prepared, it is necessary to adjust the product. Surface frosting treatment not only increases the production cost, but also the produced surface functional coating is often difficult to be stably combined with the product itself, so it is difficult to have ideal performance

Embodiment 1

[0027] Step 1: Weigh 9 parts of low-molecular-weight SEBS, 27 parts of high-molecular-weight SEBS, 25 parts of OIL, 18 parts of polypropylene, 20 parts of filler, 0.2 parts of lubricant and 0.8 parts of sanding agent by mass parts, add to the mixing tank and stir evenly ;

[0028] Step 2: Add the uniformly stirred material in step 1 into the twin-screw extruder, set the operating temperature of the twin-screw extruder to 195°C, and extrude. After extrusion, send the extruded material into the cooling water tank for cooling , and then use a granulator to granulate to make pellets;

[0029] Step 3: Add the granular material in Step 2 into a large mixing tank, fully stir, mix evenly, and pack to obtain the rubber material.

Embodiment 2

[0031] Step 1: Weigh 9 parts of low-molecular-weight SEBS, 27 parts of high-molecular-weight SEBS, 25 parts of OIL, 16.8 parts of polypropylene, 21 parts of filler, 0.2 parts of slippery agent and 1 part of sanding agent in parts by mass, add to the mixing tank and stir evenly ;

[0032] Step 2: Add the uniformly stirred material in step 1 into the twin-screw extruder, set the operating temperature of the twin-screw extruder to 195°C, and extrude. After extrusion, send the extruded material into the cooling water tank for cooling , and then use a granulator to granulate to make pellets;

[0033] Step 3: Add the granular material in Step 2 into a large mixing tank, fully stir, mix evenly, and pack to obtain the rubber material.

Embodiment 3

[0035] Step 1: Add 6 parts of low-molecular-weight SEBS, 30 parts of high-molecular-weight SEBS, 25 parts of OIL, 17 parts of polypropylene, 19.8 parts of filler, 0.2 parts of lubricant and 2 parts of sanding agent in parts by mass, add to the mixing tank and stir evenly;

[0036] Step 2: Add the uniformly stirred material in step 1 into the twin-screw extruder, set the operating temperature of the twin-screw extruder to 195°C, and extrude. After extrusion, send the extruded material into the cooling water tank for cooling , and then use a granulator to granulate to make pellets;

[0037] Step 3: Add the granular material in Step 2 into a large mixing tank, fully stir, mix evenly, and pack to obtain the rubber material.

[0038] It should be noted here that Formosa Plastics 150N is used as the OIL in the above examples, calcium carbonate produced by Meilitai is used as the filler, CROSS-INKCD CMA is used as the abrasive agent, and conventional silicone masterbatch is used as t...

Abstract

The invention relates to the technical field of high polymer materials, in particular to a rubber material with a frosted effect and a preparation method of the rubber material. The rubber material comprises, by mass, 20 to 36 parts of SEBS; 15 to 30 parts of OIL; 8 to 19 parts of polypropylene; 15 to 25 parts of a filler; 0.1 to 0.2 part of a lubricating agent; and 0.5 to 2 parts of a dull polishagent. The rubber material disclosed by the invention is prepared by compounding SEBS, OIL, polypropylene, the filler, the lubricating agent and the dull polish agent, is good in mechanical propertyand soft and smooth in material, has a dull polish effect on the surface, and can meet the use requirements of people on wearable products made of the rubber material; the preparation method disclosedby the invention is simple in process, easy to operate and low in production and processing cost, and can meet the industrial production and manufacturing requirements.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a rubber material with a frosting effect and a preparation method thereof. Background technique [0002] Rubber material is a kind of polymer material, which is widely used in various fields. With the continuous development of rubber material, the performance of rubber material has higher requirements while the scope of use is expanding. [0003] The appearance of products with partial frosting effect is more cool and comfortable to wear. Therefore, when rubber materials are used to manufacture some wearable products, not only the rubber materials must have good mechanical properties, but also new requirements for the appearance of molded products. It is required to have a matte effect and feel smoother, but the wearable products made of rubber materials in the traditional technology do not meet the above requirements. In the traditional technology, in order to achieve ...
