Abstract

The invention discloses a kind of basic zirconium phosphate fire retardant and preparation method thereof, belong to the technical field of fire retardant, the preparation method comprises the following steps:(1)By hypophosphorous acid, phosphoric acid, 2(Methylamino)Ethanol mixes, and heating, adds methanol thereafter, synthesizes hypophosphorous acid compound;(2)Hypophosphorous acid compound and basic zirconium phosphate are mixed to get the fire retardant combination.The fire retardant combination flame retardant effect of the present invention is good, has environment friendly.

Description

A kind of basic zirconium phosphate fire retardant and preparation method thereof
Technical field
The present invention relates to the technical field of the technical field of fire retardant, the more particularly to fire retardant of phosphoric acid zirconium.
Background technology
In the industries such as weaving, leather, to ensure that flame retardant effect, and material quality, past often use halogenated flame retardant.But halogen Flame retardant can discharge a large amount of toxic and harmful gas when burning, and the harm to human body and environment is larger.
Therefore in recent years, the focus that halogen-containing fire retardant is always research, wherein phosphorus system are substituted using halogen-free flame retardants Fire-retardant is a kind of best environmentally friendly halogen-free flame retardants of application potential, and expansion character when its is fire-retardant, which effectively reduces, poisonous to be had The diverging of evil gas.
Can be with but conventional phosphorus flame retardant and preventing and treating fiber, the compatibility of the biomaterial such as leather are poor, after being directly added into Stable phase structure is maintained with system, the phosphorus flame retardant added after modified can generally be made to the other performance of biomaterial again Into harmful effect.
The content of the invention
It is an object of the invention to propose that it is compatible that one kind can be stablized with biomaterial and its additive, and material can be improved Washability, not basic zirconium phosphate fire retardant of attacking material mechanical property and preparation method thereof.
Technical scheme is as follows:
A kind of preparation method of basic zirconium phosphate fire retardant, it comprises the following steps:
(1)By hypophosphorous acid, phosphoric acid, 2-(Methylamino)- ethanol mixes, and is heated at 80 ~ 120 DEG C, adds methanol thereafter, synthesizes N, N-2(2- ethoxys-methylamino)Hypophosphorous acid, i.e. hypophosphorous acid compound;
(2)After the hypophosphorous acid compound is mixed with basic zirconium phosphate, that is, obtain the basic zirconium phosphate fire retardant.
Preferably:The step(1)Described in hypophosphorous acid, phosphoric acid, 2-(Methylamino)- ethanol, the mass ratio of methanol are 1 ~1.2:1:1~1.5:1~2。
It is also preferred that:The step(2)Described in the mass ratio of hypophosphorous acid compound and basic zirconium phosphate be 0.5 ~ 1:1.
It is also preferred that:The step(1)The time of middle heating is 30 ~ 60min.
The present invention proposes a kind of basic zirconium phosphate fire retardant simultaneously, and it is according to any of the above-described kind of preparation method or its preferred scheme It is prepared.
The fire retardant combination of the present invention is halogen-free flame retardants, has environment friendly, biology can be effectively isolated when fire-retardant Toxic gas caused by material and its additive, flame retardant effect is good, while can be with the material such as textile fabric, leather and its adding Dosage form is added to make material property stable, homogeneous, fire retardant combination of the invention can significantly improve material into stable phase structure Washability, while other mechanical properties of material will not be damaged.
Embodiment
The present invention is described in further detail by the following examples, but this should not be interpreted as into the scope of the present invention It is only limitted to following example.In the case where not departing from above method thought of the present invention, according to ordinary skill knowledge and The various replacements or change that customary means is made, should be included in the scope of the present invention.
