Problems solved by technology

However, most of the existing zirconium phosphate pillared compounds are quaternary ammonium cations. The disadvantage is that the temperature resistance is lower than 200°C, and the molding processing temperature of general plastics is above 200°C, thus limiting its application range.
At present, there are no relevant reports on the preparation of antibacterial powders with quaternary phosphonium cationic pillared zirconium phosphate

Embodiment 1

[0041] Weigh 5.82g (0.02mol) of layered α-ZrP and disperse it in 300mL of water. After the dispersion is complete, add 12g of 25% methylamine (MA) solution (containing 0.10mol of methylamine) to the dispersion, and dissolve it at 60°C. After stirring for 2h, MA-ZrP solution was obtained after stirring. Then add 8.12g (0.02mol) of dodecyltributylphosphorus bromide to the MA-ZrP solution, stir, react at 25°C for 6h, filter the reaction product, wash the solid with distilled water until it is detected with silver nitrate solution Filtrate free of bromide ions, vacuum at 90°C (vacuum degree is 2×10 4 Pa) drying for 24h to obtain the initial product, then superfinely pulverized to an average particle diameter of less than 5 microns to obtain a quaternary phosphonium pillared layered zirconium phosphate material (according to the TGA analysis results, the chemical formula is ). The test results are shown in Table 1.

Embodiment 2

[0043] Weigh 5.82g (0.02mol) of α-ZrP and disperse it in 300mL of water. After the dispersion is complete, add 6g of 25% methylamine (MA) solution (containing 0.05mol of methylamine) to the dispersion, and stir at 65°C for 3h , and the MA-ZrP solution was obtained after stirring. Then add 32.48g (0.08mol) dodecyltributylphosphorous chloride to the MA-ZrP solution, stir, react at 30°C for 5h, filter the reaction product, wash the solid with distilled water until it is detected with silver nitrate solution Filtrate free of chloride ions, vacuum at 80°C (vacuum degree is 2×10 4 Pa) drying for 20h to obtain the initial product, then superfinely pulverized to an average particle diameter less than 5 microns to obtain a quaternary phosphonium pillared zirconium phosphate material (according to the TGA analysis results, the chemical formula is ). The test results are shown in Table 1.

Embodiment 3

[0045] Take by weighing 5.82g (0.02mol) α-ZrP and be dispersed in 300mL water, treat to disperse completely, add 2.4g (0.02mol) 25% methylamine (MA) solution (containing methylamine 0.02mol) in this dispersion liquid, in Stir at 40°C for 1 h, and after stirring, a MA-ZrP solution is obtained. Then add 0.0894g (0.0002mol) dedecyltriphenylphosphine bromide to the MA-ZrP solution, stir, react at 20°C for 4h, filter the reaction product, wash the solid with distilled water until the filtrate is detected with silver nitrate solution No bromide ions, vacuum at 80°C (vacuum degree is 2×10 4 Pa) drying for 24h to obtain the initial product, then superfinely pulverized to an average particle size less than 3 microns, to obtain a quaternary phosphonium pillared zirconium phosphate material (according to the TGA analysis results, the chemical formula is ). The test results are shown in Table 1.

Abstract

The invention discloses a quaternary phosphonium salt pillared layered zirconium phosphate material, and a preparation method and an application thereof. The chemical formula of the quaternary phosphonium salt pillared layered zirconium phosphate material is as follows, R is methyl, butyl, phenyl or alkane with the length of a carbon chain of 8-20; X is Cl or Br; and m is 1, and n is 0.00288-0.174462. The preparation method comprises the steps of utilizing methylamine to prop up an interlayer spacing interval of zirconium phosphate, obtaining a methylamine-zirconium phosphate precursor, then adding a quaternary phosphonium salt into the methylamine-zirconium phosphate precursor for continuously carrying out reaction for a certain time, replacing the methylamine in the precursor and obtaining the quaternary phosphonium salt pillared layered zirconium phosphate material with white or light gray external appearance, and the quaternary phosphonium salt pillared layered zirconium phosphate material can be added into plastics, rubber, fibers, coatings, adhesives, paper and other materials for preparing an antibacterial or flame-retardant functional material, and be also used for removing algae in water and governing large-area red tide and water blooms in fresh water.

Description

technical field [0001] The invention relates to an organic-inorganic hybrid material and its preparation method and application, in particular to a quaternary phosphide pillared layered zirconium phosphate material and its preparation method and application. Background technique [0002] Layered clay is a good carrier of functional substances because of its exchangeable hydrated cations and strong adsorption performance between layers. The functional organic matter is inserted between the layers of the layered clay to form molecular-level composites with the layered clay to obtain insoluble pillared compounds. Because the heat resistance of the functional organic compounds in the pillared compound is greatly improved and the toxicity is reduced, the performance is stable and long-lasting. [0003] Phosphate is a new type of cationic layered compound developed in recent years, and its chemical formula can be given by the general formula M(HPO4) 2 ·H 2 O (abbreviated as MP,...
