Abstract
The invention relates to a method to produce zinc borate. First, equably mixing boracic acid and zinc oxide; second, pouring boracic acid and zinc oxide into reaction container, adding water, milling to flow state; third, sealing the reaction container and keeping constant temperature at a certain temperature for a while; fourth, the container cooling to room temperature and taking out the production for drying. The invention discloses simple technology, and need not filtration and washing. It can be used both for flame retardant material and commodity chemical industry and biology medicine.
Description
Technical field
The invention belongs to technical field of inorganic material, more specifically relate to a kind of preparation method of zinc borate, this product is used for fire retardant material, also can be used for fields such as daily-use chemical industry, biological medicine.
Background technology
According to bibliographical information, the existing method for preparing zinc borate mainly contains following several: be raw material with borax and zinc sulfate 1,, stir synthetic zinc borate in heated in water solution.Owing to two kinds of by products are arranged in this method reaction process, make separation circuit numerous and diverse [USP 3,649,172]; 2, be that raw material synthesizes zinc borate with zinc hydroxide and boric acid.This method needs on-site preparation zinc hydroxide [GB 1,348,900]; 3, be raw material with zinc oxide and boric acid, heated in water solution stir synthetic zinc borate [Zou Xuhua. the study on the synthesis [J] of BACN zinc borate (2335). use chemical industry, 2001,30 (2): 32～33].This method need add excessive boric acid in proportioning, with method 1 the same filtration, the water washing process of needing equally, although mother liquor can reuse, but the problem that exists boron loss and water to discharge.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of zinc borate.This method technological process simply, neither needs to filter, and does not also need water washing process, the reaction yield height.Products obtained therefrom purity height, there is not by product.
In order to realize that the technical measures that purpose of the present invention is taked are:
A kind of method for preparing zinc borate: 1) zinc oxide and boric acid (mol ratio is 1: 3) are mixed; 2) pour in the reaction vessel, add a certain amount of water (amount of water be zinc oxide and boric acid total mass 0.01%～60%), stir and be mixed with rheology attitude (the rheology attitude is non-ly consolidated non-liquid state for what is made up of zinc oxide, boric acid and water); 3) reaction vessel is airtight, and under 60～100 ℃ of temperature constant temperature 6～12 hours, reaction vessel is an encloses container; 4) treat that container is chilled to 20～30 ℃ of room temperatures after, take out product, 120～140 ℃ of oven dry down, promptly obtain the zinc borate product.5) preparation process does not need to filter, do not need washing.
Compared with prior art, the beneficial effect that adopts technical scheme of the present invention and reached:
Preparation method's technological process of the present invention is simple, does not need filtration, water washing process, and the reaction yield height is near 100%.Production process is accomplished zero release, is particularly suitable for industrial production.This product is used for fire retardant material, also can be used for fields such as daily-use chemical industry, biological medicine.
Embodiment
Example 1: take by weighing 3.24 gram zinc oxide and 7.24 gram boric acid respectively, after the mixing, add 6.00g water, be modulated into the rheology attitude, change in the encloses container in 80 ℃ of reactions 12 hours, be chilled to room temperature after, take out reaction product, directly oven dry obtains needed zinc borate product.
Example 2: take by weighing 1.62 gram zinc oxide and 3.71 gram boric acid respectively, after the mixing, add 0.05g water, be modulated into the rheology attitude, change in the encloses container in 100 ℃ of reactions 6 hours, be chilled to room temperature after, take out reaction product, directly oven dry obtains needed zinc borate product.
Example 3: take by weighing 3.24 gram zinc oxide and 7.24 gram boric acid respectively, after the mixing, add 6.00g water, be modulated into the rheology attitude, change in the non-encloses container in 80 ℃ of reactions 12 hours, be chilled to room temperature after, take out reaction product, directly oven dry can not get needed zinc borate product.
Claims (2)
1, a kind of preparation method of zinc borate comprises the following steps:
A, zinc oxide and boric acid are mixed, mol ratio is 1: 3;
B, pour reaction vessel into, add entry, the amount of water is 0.01%～60% of zinc oxide and a boric acid total mass, stirs to be mixed with the rheology attitude;
C, reaction vessel is airtight, constant temperature is 6～12 hours under 60～100 ℃ of temperature;
D, treat that container is chilled to 20～30 ℃ of room temperatures after, take out product, 120～140 ℃ of oven dry down, promptly obtain the zinc borate product.
2, the preparation method of a kind of zinc borate according to claim 1 is characterized in that reaction vessel is an encloses container.
