Embodiment 1

[0012] This non-crystalline rosin comprises the following production steps:

[0013] Under stirring state, put 100kg rosin, 1kg petroleum sodium sulfonate and 1kg particle diameter into the cobblestone powder of 1 micron, then heat to 300 ℃, carry out reaction; When described rosin dissolves completely, stop stirring, After standing still for 10 minutes, discharge the material.

Embodiment 2

[0015] This non-crystalline rosin comprises the following production steps:

[0016] Under stirring state, 100kg rosin, 4kg petroleum sodium sulfonate and 4kg particle diameter are put into the cobblestone powder of 4 microns, then heated to 350 ℃, carry out reaction; When described rosin dissolves completely, stop stirring, After standing still for 15 minutes, discharge the material.

Embodiment 3

[0018] This non-crystalline rosin comprises the following production steps:

[0019] Under stirring state, 100kg rosin, 3kg petroleum sodium sulfonate and 3kg particle diameter are put into the cobblestone powder of 6 microns, then heated to 320 ℃, carry out reaction; When described rosin dissolves completely, stop stirring, After standing still for 12 minutes, discharge.

Abstract

The invention discloses a production method of non-crystallized rosin, which belongs to the technical field of rosin deep processing. The invention comprises putting 100 parts by weight of rosin, 1 to 4 parts by weight of sodium petroleum sulfonate and 1 to 4 parts by weight of cobblestone powder with a particle diameter of 1 to 6 microns in a stirring state, Then heat to 300° C. to 350° C. for reaction; when the rosin is completely dissolved, stop stirring, let stand for 10 minutes to 15 minutes, and then discharge. The invention adds sodium petroleum sulfonate and pebbles of specific particle size to the melted rosin, thereby effectively preventing and delaying the crystallization of the rosin, preventing the rosin from forming crystals during solidification, thereby achieving the purpose of anti-crystallization.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a production method of non-crystallized rosin. Background technique [0002] Rosin refers to a non-volatile natural resin obtained from pine rosin through different processing methods. The color of rosin is burnt yellow and deep red. It is an important chemical raw material. In daily life, it is mainly used as flux in the soldering of circuit boards. In terms of musical instruments, rosin is applied to the bow hair of erhu, violin, matouqin and other string instruments to increase The friction of the bow hairs against the strings. For learning ballet, rosin acts as an anti-slip effect. [0003] Rosin has a crystallization tendency, and the transparency and solubility of rosin after crystallization are greatly reduced, which greatly reduces its use value. Therefore, rosin needs to be treated accordingly to prevent its crystallization. Contents of the...
