Abstract
The invention provides a method for preparing hexagonal flake magnesium hydroxide with dominant growth on a (001) crystal face. The method comprises the following steps: dispersing a magnesium hydroxide raw material into a sodium hydroxide solution in a ball milling manner, and performing ball-milling so as to prepare slurry with the solid content of 5-30%; adding the ground magnesium hydroxide slurry into a hydrothermal reactor lined with polytetrafluoroethylene, and performing hydrothermal treatment in a temperature range from 120 DEG C to 200 DEG C; and cooling, filtering and washing the product after the reaction is completed, and drying the product in a drying oven. The hexagonal flake magnesium hydroxide is added into polyethylene, so that the oxygen index of the polyethylene can be improved from 19.2% to 22.6% by virtue of the magnesium hydroxide, and the flame retardant property is enhanced. The polyethylene material added with the hexagonal flake magnesium hydroxide is of a meshed structure, the tensile strength of the polyethylene is improved, while the elongation at break is reduced along with increase of the addition amount. The modified magnesium hydroxide and the polyethylene material have high compatibility, and the mechanical property of the polyethylene can be maintained.
Description
Technical field
The invention belongs to technical field of inorganic chemical industry is related to a kind of preparation of flame retardant of magnesium hydroxide, and in particular to a kind of
(001) preparation technology of the hexagonal plate magnesium hydroxide fire retardant of crystal face dominant growth.
Background technology
With the progress of society, macromolecular material has also obtained the macromolecule materials such as swift and violent development, plastics, rubber, fiber
Material is also widely used for the fields such as chemical industry, Aero-Space, automobile, building trade.Be indispensable life in people's life,
The producer goods.But most of macromolecule product easily burns, and the product of dense smoke and toxic gas is generally entailed in combustion process
Raw, this life and property safety to the mankind constitutes grave danger, while also severe contamination can be caused to environment.The fire for taking place frequently
Calamity forces people to put forward higher requirement the fire resistance of various materials.
Magnesium hydroxide is a kind of thermally-stabilised good, nontoxic, suppression cigarette inorganic additive flame retardant.Generate in combustion
Water and magnesium oxide are not polluted to air, and are also had in neutralization combustion process while corrosive gas is not produced
The acidity and corrosive gas function of generation, is a kind of fire retardant of environmental protection, and the heat decomposition temperature of magnesium hydroxide is higher,
About 140 DEG C are higher by than aluminium hydroxide, fire proofing can be made to bear higher processing temperature, beneficial to extrusion molding speed is accelerated, shortened
Molding cycle.It is the inorganic combustion inhibitor kind very with development prospect.
Magnesium hydroxide although have the advantages that it is many, but there is also some defects, the flame retarding efficiency of magnesium hydroxide is relatively low, hydrogen
Magnesium oxide will reach the addition of flame retardant effect than larger, and run-of-the-mill fraction reaches 60%, due to the big magnesium hydroxide of addition
Poor with the compatibility of macromolecular material, this can be damaged to the mechanical performance and processing characteristics of polymer composite.
So using hydro-thermal method in magnesium hydroxide after dissolve-repreparation herein so that the weaker crystal face of its polarity fully appears, therefore
With lower surface polarity, while dispersibility is improved, mean diameter reaches 11 μm or so of hexagonal plate magnesium hydroxide.
The content of the invention
It is an object of the invention to provide a kind of preparation method of hexagonal plate magnesium hydroxide, obtain that surface polarity is low, dispersion
The good, mean diameter of property is 1 μm or so of hexagonal plate magnesium hydroxide.
The preparation method of the hexagonal plate magnesium hydroxide of one kind (001) crystal face dominant growth of the invention, its step is as follows：
(1) raw material magnesium hydroxide is distributed in sodium hydroxide solution in the way of ball milling, ball milling is configured to solid content and is
5%～30% slurry.
(2) ground magnesium hydroxide slurry is added in the water heating kettle of inner liner polytetrafluoroethylene, temperature be 120～
Hydrothermal treatment consists are carried out in the range of 200 DEG C.
(3) product will be cooled down after the completion of reaction, is filtered, washing is put into oven drying.
The concentration of sodium hydroxide is 4～8mol/L in described step (1).
Ball-milling Time described in described step (1) is 8～12h.
The time of hydrothermal treatment consists is 4～10h in described step (2).
The time being dried in described step (3) is 8～12h.
The present invention is prepared for the hexagonal plate magnesium hydroxide fire retardant of (001) crystal face dominant growth.By the hydrogen of certain mass
Magnesium oxide and sodium hydroxide solution are poured in screw socket bottle carries out ball milling dispersion, and then scattered serosity is added in water heating kettle
Dissolving-recrystallization is carried out in the range of 120～200 DEG C of temperature.Filter after cooling, wash, be dried.By magnesium hydroxide dissolving-
After recrystallization, it is completely homogeneous to have obtained crystal morphology, and corner angle are clearly demarcated, edge clear, the hexagonal plate magnesium hydroxide in rule.And
And the weaker crystal face ((001) crystal face) of its polarity of the hexagonal plate magnesium hydroxide of preparation is appeared so that the polarity drop of crystal
It is low, reunite and reduce.Simultaneously dispersibility is improved, and mean diameter reaches 11 μm or so.The magnesium hydroxide tool of crystal pattern
There is the different shape characteristic of common crystal pattern, so because their special appearance is to height when they are added in macromolecular material
Molecule plays different effects, and the particle diameter of hexagonal plate magnesium hydroxide is less with thickness ratio, easily with resin mixing, to macromolecule
The physical and mechanical propertiess of polymer affect little.
The magnesium hydroxide of hexagonal plate is added to into result in polyethylene and finds that magnesium hydroxide can refer to the oxygen of polyethylene
Number brings up to 22.6% from 19.2%, enhances its fire resistance.The polythene material of addition hexagonal plate magnesium hydroxide is in net
Shape structure, improves the tensile strength of polyethylene, but elongation at break is then reduced with the increase of addition, and modified
Magnesium hydroxide preferably, is able to maintain that the mechanical property of polyethylene with the polythene material compatibility.
