Embodiment 1-11

[0045] As described in Table 1, the main difference of Examples 1-11 is that the proportioning ratio of raw materials is different.

[0046] The following is illustrated by taking Example 1 as an example. The specific formula for its implementation is: 30Kg of polylactic acid, 15Kg of nanocellulose, 45Kg of HDPE, 15Kg of LDPE, 0.05Kg of oleic acid, and 1Kg of the first masterbatch.

[0047] The preparation method of embodiment 1 rattan is as follows:

[0048] S1. Weigh the raw materials according to the formula and place them in a mixer. Stir for 20 minutes at a heating temperature of 60°C and a stirring speed of 150 r / min to fully mix the raw materials to form a mixture.

[0049] S2, add the mixture in step S1 to the extruder from the first zone where the barrel temperature is 120-130°C; The third zone advances at -160°C, and plasticizes in the fourth zone with a temperature of 180-185°C and the fifth zone with a temperature of 185-190°C; finally, the compound is extruded fr...

Embodiment 12-18

[0054] As described in Table 1, the main difference of Examples 12-18 lies in the composition and proportioning of raw materials.

Embodiment 12

[0056] The preparation method of embodiment 12 rattan is as follows:

[0057] S1. Weigh the raw materials according to the formula and place them in a mixer. Stir for 20 minutes at a heating temperature of 60°C and a stirring speed of 150 r / min to form a mixture.

[0058] S2, add the mixture in step S1 to the extruder from the first zone where the barrel temperature is 120-130°C; The third zone advances at -160°C; the second masterbatch is added to the extruder from the fourth zone where the barrel temperature is 180-185°C, and the compound and the second masterbatch are in the fourth zone and the temperature is 185- The fifth zone at 190°C is plasticized; the final mixture and the second color masterbatch are extruded from the head of the sixth zone to form a green body, and the screw speed is 25r / min.

[0059] S3, water cooling the green body in step S2, the water cooling temperature is 5-10°C, the cooled green body is under the action of the traction device, first absorbs ...

Abstract

The invention relates to the field of high polymer material preparation, and particularly discloses a rattan and a preparation method thereof. The rattan is prepared from the following raw materials in parts by weight: 30-35 parts of polylactic acid, 15-20 parts of nanocellulose, 60 parts of a PE mixture, 0.05-0.1 part of oleic acid and 1-3 parts of first color master batches, wherein the PE mixture comprises HDPE and LDPE. The preparation method of the rattan comprises the following steps: weighing corresponding parts of raw materials, fully mixing, adding into an extruder, extruding, plasticizing, forming and cooling to obtain the rattan. The rattan can be used for weaving various furniture and has the advantage of being degradable, and environmental pollution is reduced; in addition, the rattan prepared by the preparation method has stripes, so that the rattan is rich in artistic atmosphere.

Description

technical field [0001] The application relates to the field of polymer material preparation, more specifically, it relates to a rattan and a preparation method thereof. Background technique [0002] Rattan is a tough, extremely long vine. A long time ago, people used rattan to weave various furniture, such as tables, chairs, beds and storage cabinets. The original processing procedure of rattan is quite tedious, including cooking, drying, bleaching, anti-virus, disinfection and sterilization; and because natural rattan is easily eaten by insects and corroded, its service life is not long. [0003] With the development of technology, the rattan of many rattan furniture is imitated by plastic; the plastic has excellent characteristics such as waterproof, sun protection, and stable performance, which prolongs the service life of the rattan. The main components of imitation rattan in the related art are high-density polyethylene (HDPE) and low-density polyethylene (LDPE), whic...
