Abstract
The invention discloses a process for synthesizing zinc pentaerythritol in a heat stabilizer, and relates to the technical field of chemical preparation. The particular process includes respectively weighing activated zinc oxide and pentaerythritol powder according to a molar mass ratio of 3:2; placing the activated zinc oxide and the pentaerythritol powder in a high-speed mixer, mixing the activated zinc oxide and the pentaerythritol powder in the high-speed mixer at the rotational speed of 1300-1500 r/min, mixing and stirring the activated zinc oxide and the pentaerythritol powder for 20 minutes to obtain mixtures and carrying out reaction on the mixtures in a reactor for the reaction time of 45-90 min; cooling products until the temperatures of the products reach the room temperature; grinding the products by the aid of an ultrafine grinder to obtain the zinc pentaerythritol. The process has the advantages that the process for preparing the zinc pentaerythritol is simple, and the zinc pentaerythritol prepared by the aid of the process has initial-stage coloring resistance just like zinc stearate and is high in zinc burning inhibiting capacity and long-term heat stability.
Description
Technical field:
The present invention relates to a kind of heat stabilizer penta tetrol zinc synthesis technique, belong to chemical industry preparing technical field.
Background technology:
In PVC stabilizer, tetramethylolmethane does not has thermal stability result when being used alone, and tetramethylolmethane is due to water solublity relatively
By force, poor with PVC and plasticizer compatbility, it is deposited on equipment in the course of processing, hinders being smoothed out of processing, and affect system
The transparency of product, it is also possible to bloom phenomenon occurs.
Summary of the invention:
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of heat stabilizer penta tetrol zinc synthesis work
Skill.
The heat stabilizer penta tetrol zinc synthesis technique of the present invention.It concrete synthesis technique be: according to molal weight ratio
Ratio for 3:2 weighs activated zinc oxide and tetramethylolmethane powder respectively, then puts into mixed to activated zinc oxide and tetramethylolmethane powder
High-speed mixer mixes, and the rotating speed of high-speed mixer is 1300r/min-1500r/min, and mix and blend is placed on reaction in 20 minutes
Reacting in device, wherein the response time is 45min-90min, after reaction terminates, after product is cooled to room temperature, uses ultra micro
Pulverizer is pulverized and is obtained tetramethylolmethane zinc.
As preferably, the reaction temperature of described reactor is: 90 DEG C-150 DEG C, vacuum be :-50KPa to-
100Kpa。
Beneficial effects of the present invention: its preparation technology is simple, and raw material is easy to get, the tetramethylolmethane zinc prepared possesses to be had firmly
The anti-initial coloring of fat acid zinc, and the most also there is the ability that stronger suppression zinc burns, long-term thermal stability is stronger.
Accompanying drawing illustrates:
For ease of explanation, the present invention is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is the interpretation figure in the embodiment of the present invention 1.
Detailed description of the invention:
As it is shown in figure 1, this detailed description of the invention is by the following technical solutions: its concrete synthesis technique is: according to mole
Mass ratio is that the ratio of 3:2 weighs activated zinc oxide and tetramethylolmethane powder, respectively then by activated zinc oxide and tetramethylolmethane powder
Mixed putting into high-speed mixer mixing, the rotating speed of high-speed mixer is 1300r/min-1500r/min, and mix and blend 20 minutes is rearmounted
Reacting in reactor, wherein the response time is 45min-90min, after reaction terminates, after product is cooled to room temperature, makes
Pulverize with super micron mill and obtain tetramethylolmethane zinc.
As preferably, the reaction temperature of described reactor is: 90 DEG C-150 DEG C, vacuum be :-50KPa to-
100Kpa。
Embodiment 1: weigh activated zinc oxide respectively and tetramethylolmethane powder 121.5g and 136.0g adds in high-speed mixer
Mixing, wherein the rotating speed of high-speed mixer is 1500r/min, mixes and is placed in there-necked flask for 5 minutes, and reaction temperature is arranged:
140 DEG C, vacuum :-100KPa, reaction 60min, stirring 1000r/min, reaction terminate after, after product is cooled to room temperature, make
Pulverize with super micron mill and obtain tetramethylolmethane zinc C.
Zinc stearate A, tetramethylolmethane B and tetramethylolmethane zinc C are carried out oven ageing Experimental comparison
Wherein A: zinc stearate: brucite 1:1
B: tetramethylolmethane: brucite 1:1
C: tetramethylolmethane zinc: brucite 1:1
Fig. 1 is interpretation figure, and with reference to shown in Fig. 1, the tetramethylolmethane zinc prepared possesses the anti-of zinc stearate
Initial coloring, has and has the ability that stronger suppression zinc burns.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
