Abstract
The invention discloses a preparation method of non-crystallizable rosin, and belongs to the technical field of rosin deep processing. The preparation method includes the steps that firstly, by weight, 100 parts of rosin, 1-4 parts of isoprene, 1-4 parts of sodium citrate and 1-4 parts of rosin are put into a reactor; then, the mixture is heated to 380-400 DEG C to make all solid materials completely dissolved and then is cooled to 265-280 DEG C, and the mixture is reacted for 1-3 h. The obtained product is good in crystallization resistance.
Description
Technical field
The invention belongs to Colophonium deep process technology field, particularly relate to a kind of preparation method not crystallizing Colophonium.
Background technology
Colophonium, refers to pine resin as raw material, the non-volatile natural resin obtained by different processing modes.The color of Colophonium is sallow dark red, is important industrial chemicals, and daily life aspect makees scaling powder when being used primarily in welding circuit board, and in terms of musical instrument, Colophonium is applied on the bow hair of the string musics such as urheen, violin, matouqin for increasing the bow hair friction to string.For study ballet aspect, Colophonium plays anti-skidding effect.
Colophonium has crystallization tendency, and Colophonium transparency and dissolubility after crystallization significantly decline, and greatly reduce its use value.It is stoped to crystallize accordingly, it would be desirable to Colophonium is processed accordingly.
Summary of the invention
The present invention provides a kind of production method not crystallizing Colophonium, solves the problem that conventional Colophonium has crystallization tendency.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
The raw material of its following weight portion of employing:
Under stirring, 100 weight portion Colophonium, 1 weight portion～4 parts by weight of isoprene, 1 weight portion～4 parts by weight of lemon acid sodium and 1 weight portion～4 weight portion Colophonium are put in reactor, the most first heating 380 DEG C～400 DEG C makes all of solid material all dissolve, it is cooled to 265 DEG C～280 DEG C again, carries out reacting 1 hour～3 hours.
Owing to using technique scheme, there is advantages that
The present invention is by adding isoprene, sodium citrate and Colophonium in melted Colophonium, thus effectively stops and delay CRYSTALLIZATION OF ROSIN, makes Colophonium be unlikely formation crystal when solidification, thus reaches the purpose that resistive connection is brilliant.
Detailed description of the invention
Below in conjunction with instantiation, the invention will be further described:
Embodiment 1
This does not crystallize Colophonium and includes following preparation process:
Under stirring, putting in reactor by 100kg Colophonium, 4kg isoprene, 4kg sodium citrate and 4kg Colophonium, the most first heating 380 DEG C makes all of solid material all dissolve, then is cooled to 280 DEG C, carries out reacting 1 hour.
Embodiment 2
This does not crystallize Colophonium and includes following preparation process:
Under stirring, putting in reactor by 100kg Colophonium, 3kg isoprene, 3kg sodium citrate and 3kg Colophonium, the most first heating 400 DEG C makes all of solid material all dissolve, then is cooled to 265 DEG C, carries out reacting 3 hours.
Embodiment 3
This does not crystallize Colophonium and includes following preparation process:
Under stirring, putting in reactor by 100kg Colophonium, 1kg isoprene, 1kg sodium citrate and 1kg Colophonium, the most first heating 395 DEG C makes all of solid material all dissolve, then is cooled to 275 DEG C, carries out reacting 2 hours.
The resistive connection crystalline substance Colophonium that raw material Colophonium, embodiment 1～3 prepare is carried out performance detection respectively, its result such as table 1.
Table 1
It can be seen that the resistive connection crystalline substance Colophonium that the present invention prepares not only possesses the effect that resistive connection is brilliant from above-mentioned table 1, and it is effectively maintained the performance of raw material Colophonium.
Claims (1)
1. the preparation method not crystallizing Colophonium, it is characterised in that comprise the following steps:
Under stirring, 100 weight portion Colophonium, 1 weight portion～4 parts by weight of isoprene, 1 weight portion～4 parts by weight of lemon acid sodium and 1 weight portion～4 weight portion Colophonium are put in reactor, the most first heating 380 DEG C～400 DEG C makes all of solid material all dissolve, it is cooled to 265 DEG C～280 DEG C again, carries out reacting 1 hour～3 hours.
