Description
Technical field
The present invention relates to a kind of new material, more particularly to a kind of preparation method of red phosphorus combustion inhibitor.
Background technology
During the neat product of current red phosphorus flame-retardant is the ㎜ of graininess >=3, process, inflammable and explosive, granular fire retardant
Sulphur phosphorus content in product is too high to reach 5%, and heavy metal reaches 2%, it is necessary on three processing, technical elements during use
Its yellow phosphorus content, content of beary metal, granularity in product etc. can not be solved to require.
The content of the invention
It is an object of the invention to provide a kind of preparation method of red phosphorus combustion inhibitor, solve safe in process
Problem.
The present invention is achieved in that a kind of preparation method of red phosphorus combustion inhibitor comprises the following steps：
A：Ball milling；
B:Grinding；
C：Soda boiling；
D:Glue；
E:Microcapsules react；
F：Water removal；
G：Dry；
H：Screening；
I：Packaging.
The present invention further technical scheme be：In the step A, the red phosphorus is added into ball mill, the ball mill
Cylinder, ball forges aluminous refractory more than AL2O3 >=65 and is made.
The present invention further technical scheme be:In the step B, the good red phosphorus of ball milling is added into grinder, it is described to grind
Zirconium ball in grinding machine, is high intensity, wear-resisting, refractory material.
The present invention further technical scheme be：In the step D, the glue is to add 40 into ground red phosphorus
The melamine of parts by weight, the trimerization methanol of 8-10 parts by weight, three ethanolic hydrogen amine of 20 parts by weight, 8 parts sulfuric acids, 25 weight
The fossil meal of part, the caustic soda of 8 parts by weight is raised to 300 degree by oil, reacts 8 hours.
The present invention further technical scheme be：In the step E, the reaction time is no less than 4 hours.
The present invention further technical scheme be：In the step F, the method for water removal removes water for centrifugation.
The present invention further technical scheme be：The step G is：Material after water removal is put into vacuum drying chamber to dry
Dry, the vacuum drying chamber is by water by electrical heating, and temperature reaches 90 DEG C, is dried through stainless steel pipes, and the drying time is extremely
It is less 16 hours, is taken out from case, is cooled 30 DEG C.
The beneficial effects of the invention are as follows：A kind of red phosphorus combustion inhibitor of the present invention, flame retarding efficiency is high, reach 94V-0 grades it is fire-retardant
Standard, amount ratio conventional flame retardant few 60% is good with polymer compatibility, influences few to the physical and mechanical properties of product, auxiliary agent
Not etching apparatus, heat endurance is good, and at 300 DEG C or so without decomposition, can be used alone also can be with other flame retardant products compound uses.
Brief description of the drawings
Fig. 1 is a kind of preparation method schematic flow sheet for red phosphorus combustion inhibitor that the present invention is provided.
Embodiment
Embodiment one：The whole technological process of production of flame retardant products, ball milling is introduced into by raw material red phosphorus, but to ball mill
Cylinder, ball forging requirement must be more than AL2O3 >=65 aluminous refractory be made, reduce the content of beary metal of its product, so
It is sanded afterwards, the zirconium ball in sand mill, is also high intensity, wearing-proof refractory material, [mill is to material particle size refinement process, alkali
Boil as production process, mainly the yellow phosphorus content in removing red phosphorus.It is that product is nonflammable, explosive].Add a certain proportion of
Other chemical combination materials：The melamine of 40 parts by weight, the trimerization methanol of 8-10 parts by weight, three ethanolic hydrogen amine of 20 parts by weight, 8 weights
Part sulfuric acid (acidity 93%) is measured, the fossil meal of 25 parts by weight, the caustic soda of 8 parts by weight is raised to 300 degree by oil, reacted 8 hours,
Glue success, adding makes the reaction of its microcapsules (after 4 hours) in red phosphorus, carry out centrifugation and remove moisture content.Then, it is put into vacuum drying
Case is dried, and vacuum drying chamber is by water by electrical heating, and temperature reaches 90 degree, (after 16 hours) is dried through stainless steel pipes, from case
It is middle to take out, cool 30 degree, can be sieved, packaging and storage.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
