Abstract
The invention discloses a treatment process for reversible type thermochromic series, comprising the following steps of: a, mixing methylpolysilicone, a first part of oxhydryl polysiloxane, azyl polysiloxane with thermochromic series, adding a small quantity of silazane and glycerol, evenly stirring, stirring in a dispersing way by a cone-shaped disperser for 2-3 hours, and stewing for later use; b. mixing a second part of oxhydryl polysiloxane with acrylic acid, stirring by means of sealing and dispersing for 1 hour, and sewing, so that treating agent can be prepared; and c. mixing the thermochromic series treated by the step a with the processing agent prepared by the step b, stirring in a dispersing way by the disperser for 3 hours, heating to be 120 DEG C to 150 DEG C, heating to 150 DEG C, keeping the temperature of 150 DEG C for more than 3 hours, cooling, continuously stirring in a dispersing way till to be cooled into the room temperature, vacuumizing for 0.5 hour, and extracting. The thermochromic series treated according to the treatment technology is evenly dispersed in a silicon material, and the thermal endurance of the thermochromic series and the use times and the use reliability under normal temperature can be effectively improved.
Description
Technical field
The present invention relates to the treatment process that a kind of reversible temperature becomes powder, a kind of reversible temperature of especially in Zylox, using becomes the treatment process of powder.
Background technology
It is a kind of reversible temperature sensing material of little assisting of glue that temperature becomes powder, and it can produce 200-500 time reversible change down at 50-70 ℃, and in the prior art, owing to itself and organosilicon material property difference are bigger, powder disperses an inhomogeneous and easy particle in silicon materials.
In addition, owing under the medium occasion of kitchen tools, use, its product bears 150-200 ℃ of pyritous possibly and uses repeatedly, and the stability that this has just destroyed temperature sensing material causes shorten work-ing life or round high temperature (≤250 ℃) destroys.
Summary of the invention
For having overcome the deficiency of prior art; The object of the present invention is to provide a kind of reversible temperature to become the treatment process of powder; Become powder homodisperse in silicon materials according to the temperature after this art breading, and effectively improve the heat resistance of temperature change powder and access times and the work reliability under the conventional temperature.
Components based on weight percentage in this treatment process comprises the steps:
A. methyl polysiloxane 7%-8%, first part of hydroxyl ZGK 5 3%-4%, amino silicones 7%-8% are become powder 70%-73% with temperature and mix; Add minor amount of silicon azane and USP Kosher 0.2%-0.8%; Take the taper decollator to disperse to stir 2-3h after evenly stirring, leave standstill etc. to be used;
B. mix second part of hydroxyl ZGK 5 3%-4% and vinylformic acid 6%-7%, adopt sealing to disperse to stir 1h then, leave standstill and to prepare treatment agent;
C. will become powder through the temperature that step a handles and, disperse stirring 3h, be heated to 120 ℃-150 ℃ with the taper decollator through the treatment agent mixing that step b makes; Heat then after 150 ℃, guarantee 150 ℃ more than 3 hours, cooling also continues to disperse to stir until dropping to room temperature; Vacuumize 0.5h, take out.
Reliable for guaranteeing the temperature change opaque amount after the processing, can carry out a checking procedure again: use the methyl alcohol volumetry, when per 100 gram powders checked out the titration consumption of methyl alcohol to be 5-7g, it is qualified that the temperature change powder of step c is.
Become powder according to rule of similarity according to the temperature after this art breading; Making temperature powder and treatment agent obtain better interface contacts; Increase contacted specific surface area, increased the quantity of temperature powder outside surface organic molecule group, thereby improve temperature powder and fused with the fused better uniformity coefficient of silica gel; Make the thermal insulation protection coating of reversible temperature powder, effectively improve temperature and become the heat resistance of powder and access times and the work reliability under the conventional temperature at powder surface formation silica gel.
Embodiment
For understanding the present invention better; Through embodiment the present invention is done further concrete elaboration below; But unintelligible is to qualification of the present invention; For some nonessential improvement and adjustment that those skilled in the art is done according to the foregoing invention content, also be regarded as dropping in protection scope of the present invention.
Embodiment:
By following three steps temperature of the prior art being become powder handles:
A. methyl polysiloxane 7.16g, first part of hydroxyl ZGK 5 3.58g are become powder 71.6g with amino silicones 7.16% and temperature and mix; Add minor amount of silicon azane and USP Kosher 0.5g; Take the taper decollator to disperse to stir 2-3h after evenly stirring, leave standstill etc. to be used;
B. mix second part of hydroxyl ZGK 5 3.33g and vinylformic acid 6.67g, adopt sealing to disperse to stir 1h then, leave standstill and to prepare treatment agent;
C. will become powder through the temperature that step a handles and, disperse stirring 3h, be heated to 120 ℃-150 ℃ with the taper decollator through the treatment agent mixing that step b makes; Heat then after 150 ℃, guarantee 150 ℃ more than 3 hours, cooling also continues to disperse to stir until dropping to room temperature; Vacuumize 0.5h, take out.
After will becoming powder 100g taking-up through the temperature after three step process, carry out the titration check with the methyl alcohol volumetry, the titration consumption of test determination methyl alcohol is 6.5g, and the temperature of step c becomes powder and is salable product.
Temperature after above-mentioned volumetry titration detection is qualified becomes powder; Become powder with temperature of the prior art; Compare test; Be placed on constant temperature and humidity machine and carry out the test of high low temperature and ultimate temperature, promptly test both and change at 50-70 ℃ of high and low temperature environment and cause the temperature that the change in color number of times can both normal running with in top temperature time the, i.e. two indexs of 50-70 ℃ of irreversible temperature number of times and reversible breaking limit temperature in the form.Test result is seen table 1.
Table 1
Test shows that the temperature powder after the processing all improves a lot at 50-70 ℃ of irreversible temperature number of times and reversible breaking limit temperature, and the temperature after promptly handling becomes access times and the work reliability of powder under heat resistance and conventional temperature and all is effectively improved.
