Embodiment 1

[0024] (1) take each component raw material by the ratio given in table 1;

[0025] (2) At 60°C, mix in a high mixer for 5 minutes, and mix the above raw materials evenly;

[0026] (3) Extrude the obtained mixture in a twin-screw extruder. The extrusion temperature of each section of the extruder is respectively set to 195°C, 205°C, 215°C, 215°C, 215°C, and 225°C. The test results are shown in Table 2.

Embodiment 2

[0028] (1) take each component raw material by the ratio given in table 1;

[0029] (2) At 70°C, mix in a high mixer for 10 minutes, and mix the above raw materials evenly;

[0030] (3) Extrude the obtained mixture in a twin-screw extruder. The extrusion temperature of each section of the extruder is respectively set to 180°C, 190°C, 200°C, 200°C, 200°C, and 210°C. The test results are shown in Table 2.

Embodiment 3

[0032] (1) take each component raw material by the ratio given in table 1;

[0033] (2) At 70°C, mix in a high mixer for 15 minutes, and mix the above raw materials evenly;

[0034] (3) Extrude the obtained mixture in a twin-screw extruder. The extrusion temperature of each section of the extruder is set at 190°C, 200°C, 205°C, 205°C, 210°C, and 220°C, respectively. The test results are shown in Table 2.

Abstract

The invention discloses a polyolefin composite material having easiness in dermatoglyph die pressing and a preparation method thereof. The polyolefin composite material is formed by mixing and squeezing granulation of polyolefin resin, poly-fluorine resin, inorganic filler, compatilizer, antioxidant, coupling agent, lubricant and nucleating agent. According to the prepared polyolefin composite material, the problem that a polyolefin material is subjected to surface texture bounce after undergoing embossing can be solved well under the conditions that mechanical properties of the material and a die pressing process are not changed; thus, the polyolefin composite material can be used for dermatoglyph die pressing and is particularly suitable for various tiny dermatoglyph plates, dermatoglyph is formed easily in the die pressing process, the obtained die pressing dermatoglyph plates are clear in texture and plump, and the appearance and use range of the product are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyolefin composite material which is easy to be molded with texture and a preparation method thereof. Background technique [0002] Products with large planar structure, high strength and short molding cycle are usually formed by compression molding. Due to the appearance requirements of the molded polyolefin sheet, the surface often has some small and numerous lines. After the material is extruded and molded and cooled, due to the creep of the polyolefin material, the small lines on the surface often become unclear, and the surface texture rebounds, forming The appearance of the product is poor, which affects the use effect. [0003] The commonly used solution at present is to increase the molding temperature, increase the molding pressure or prolong the molding time to make the surface texture of the product clear. These solutions are all solved by a...
