Description
Technical field
The present invention relates to the preparation method of a kind of three hydrate zinc borates.
Background technology
Fire retardant Firebrake ZB is that United States Borax Inc. develops, and Firebrake ZB is a kind of multifunctional fire retardant, and structural formula is
XZnO YB2O3ZH2O, that the most extensive consumption of purposes is maximum is 2ZnO 3B2O33.5H2O, the most also 2ZnO 3B2O37H2O、
2ZnO 2B2O33H2O, 2ZnO 3B2O3, 3ZnO 2B2O35H2The multiple derivant such as O.
Firebrake ZB is white crystals fine-powder, water insoluble, is slightly soluble in hot water and is soluble in strong acid.Firebrake ZB is mainly used
Make fire retardant, antismoke agent, antibacterial etc., in engineering plastics to be applied to, rubber, cable, coating, pottery, glass, timber, doctor
The industries such as treatment.The fire retardant mechanism of Firebrake ZB divides three aspects: absorb heat and diluting effect, covering effect and suppression chain reaction.Boric acid
Zinc is heated to uniform temperature, i.e. releases water of crystallization, absorbs a large amount of heat energy, reduces combustion front temperature, and the moisture discharged can be dilute
Releasing the oxygen in air, suppression burning occurs, and generates boric oxide glass shape thin film simultaneously, covers and play heat insulation resistance oxygen on polymer
Effect.Firebrake ZB compounds with organohalogen compounds, and during burning, generation ZnX and boric acid overlay are in comburant surface, every
Absolutely air, and the HX that BX3 releases when burning is to stoping the chain reflex between high mars free radical to have catalytic action, from
And reach flame retardant effect more more preferable than alone Firebrake ZB.
3.5 hydrate zinc borates are the models that most widely used general consumption is maximum, 3.5 hydrate zinc borate advantages: good flame retardation effect, heat are steady
Qualitative height, dehydration temperature are high, just lose water of crystallization more than 300 DEG C.Along with Firebrake ZB is in the extensive application of every profession and trade, now towards
The direction of segmentation is developed.The fire retardant needed in some field need not reach more than 300 DEG C and just loses water of crystallization, needs relatively low
At a temperature of (200 DEG C) just can lose water of crystallization and play fire-retardant effect, and three hydrate zinc borates are because of its relatively low dehydration temperature very
Good meets needs, and three hydrate zinc borates are widely used in the necks such as papermaking, polyurethane, thermoplastic elastomer (TPE), polyolefin, rubber, PVC
Territory.
Three hydrate zinc borate overwhelming majority poor quality of market production and sales, impurity is many, and main content boron oxide content is on the low side, oxygen
Changing Zn content higher, calcination loss is on the low side, and mobility is bad, and impurity stain is many.The present invention throws by adjusting boric acid and zinc oxide
Material ratio, reaction temperature, in the range of not only making main content boron oxide, zinc oxide accomplish standard index, and calcination loss also reaches
More than 14, the production response time also shortens dramatically, and improves the utilization rate of still；Rinse through potcher, make product proportion become big
Mobility improves；Through secondary filter, well control impurity and stain.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of three hydrate zinc borates, technique is simple, yield height, low cost,
Producing without the three wastes, reaction raw materials has only to boric acid, zinc oxide and water, and reaction condition is gentle, and no coupling product and waste water produce, mother solution
Can recycle, there is not the loss of boron.The big production cost in workshop is low, and product quality is high.
The preparation method of a kind of three hydrate zinc borates of the present invention, first adds water, is subsequently adding boric acid and is warming up to 40-60
DEG C, it being subsequently adding zinc oxide, be warming up to 75-95 DEG C, blowing after reaction 6-10h, add water rinsing 15-45 minute, through accurate mistake
Filter enters centrifuge, and solid drying obtains three hydrate zinc borates.
Reaction speed of agitator controls at 60-80r/min.
The mother solution that centrifuge produces returns to reactor and recycles.
The mass ratio of water and boric acid is at 3-5:1.
The feed intake ratio of amount of material of boric acid and zinc oxide is 2.0-2.1:1.
The chemical formula 2ZnO 2B of three hydrate zinc borates of the present invention2O33H2O。
The present invention three hydrate zinc borate Testing index such as table 1:
