Embodiment 1

[0008] Example 1: (1), in parts by weight, 13 parts of bamboo leaf flavonoids, 6 parts of bamboo juice, 0.3 parts of sodium lauryl sulfonate and 5 parts of paraffin wax were homogenized at high speed for 5 minutes, and then added 100 parts (2) Add 4 parts of polypropylene and 0.05 parts of dilauryl thiodipropionate to the mixed solution in parts by weight, stir evenly, and cool to room temperature to form a premix ; (3) Put the premixed material into the granulator to extrude and granulate, and control the granulation temperature to 120°C; (4) Send the granulated granules to the film-making machine to make a film, and cut the film The artificial flute membrane can be obtained by making it into a suitable size.

Embodiment 2

[0009] Example 2: (1), in parts by weight, 31 parts of bamboo leaf flavonoids, 12 parts of bamboo juice, 2.4 parts of sodium lauryl sulfonate and 17 parts of paraffin were homogenized at high speed for 10 minutes, and then 120 parts were added thereto Heat deionized water at 120°C for 3 hours; (2) Add 7 parts of polypropylene and 0.4 parts of dilauryl thiodipropionate to the mixed solution in parts by weight, stir evenly, and cool to room temperature to form a premix ; (3), put the premix into the granulator to extrude and granulate, and control the granulation temperature to 200°C; (4), send the granulated granules to the film making machine to make a film, and cut the film The artificial flute membrane can be obtained by making it into a suitable size.

Embodiment 3

[0010] Example 3: (1), in parts by weight, 25 parts of bamboo leaf flavonoids, 8 parts of bamboo juice, 1.6 parts of sodium lauryl sulfonate and 11 parts of paraffin wax were homogenized at high speed for 7 minutes, and then 110 parts were added thereto Heat deionized water at 110°C for 2 hours; (2) Add 5 parts of polypropylene and 0.25 parts of dilauryl thiodipropionate to the mixed solution in parts by weight, stir evenly, and cool to room temperature to form a premix (3) Put the premixed material into the granulator to extrude and granulate, and control the granulation temperature to 160°C; (4) Send the granulated granules to the film-making machine to make a film, and cut the film The artificial flute membrane can be obtained by making it into a suitable size.

[0011] The artificial flute membrane that embodiment 1-3 makes and the flute membrane that nature takes are done performance comparison, and test data is as follows:

Abstract

The invention discloses a manufacturing method of an artificial flute diaphragm. The method comprises the following steps: (1) homogenizing bamboo leaf flavonoid, bamboo juice, laurinol sulfonate and paraffin at high speed for 5-10 min, adding deionized water and heating at 100-120 DEG C for 1-3h; (2) adding 4-7 parts by weight of polypropylene and 0.05-0.4 part by weight of dilauryl thiodipropionate into a mixed solution and uniformly stirring, and cooling to room temperature to obtain a premix; (3) extruding and granulating by putting the premix into a granulator, and controlling granulating temperature to 120-200 DEG C; and (4) sending the granulated particles into a film making machine to prepare a thin film, and cutting the thin film into a proper size so as to obtain the artificial flute diaphragm. The invention has the following beneficial effect: the artificial flute diaphragm obtained in the invention has basically the same toughness, timbre, transparency and the like as previous flute diaphragms prepared from reed or bamboo and is not influenced by external environment.

Description

technical field [0001] The invention relates to making flutes, in particular to a method for making artificial flute membranes. Background technique [0002] Dimembrane, attached to the second hole at the left end of the flute, is a thin film that vibrates and sounds when playing the flute. This thin film is taken from the stems of bamboo or reeds. To keep the thin film fresh, it can be stored in the refrigerator. One of the reasons why the flute is different from the flute is that the flute membrane can adjust the sound, while the flute does not need a membrane. This film is taken from the stems of bamboo or reeds. Bamboo membrane is cheaper, but it is easy to break, and the sound is not as crisp as reed membrane, so it is better to choose reed membrane. When purchasing, you should choose a beige, more transparent film. Turning blue or yellow is a sign of being too tender or too old. Dimo collection is limited by time, and can only be collected 4 to 5 days before the "Xi...
