Problems solved by technology

This is because α-Zr(HPO 4 ) 2 ·H 2 The channel between the O layers is relatively narrow, and the radius of the hydrated divalent copper ion is relatively large, so the copper ion and α-Zr(HPO 4 ) 2 ·H 2 O exchange will be more difficult
It can be seen that the existing preparation methods have shortcomings such as incomplete copper ion exchange, cumbersome exchange steps, long exchange time, and low efficiency, which limit the large-scale production and use of copper zirconium phosphate materials. This is a technology that needs to be solved urgently in this field. problem
To be precise, copper-zirconium phosphate materials have not been reported directly in the field of lubrication as lubricating additives.

Embodiment approach 1

[0012] Take 3.5 mL of zirconium nitrate solution with a concentration of 1.0 mol / L and 4.4 mL of a copper acetate solution with a concentration of 1.0 mol / L, mix and stir evenly, add 0.8 mL of phosphoric acid solution with a mass percentage of 85%, and adjust the pH value to 2 , and after 15 minutes of stirring evenly, the obtained blue gel was sealed into a polytetrafluoroethylene-lined reactor, and the reactor was placed in an oven at 180°C. After crystallization for 100 hours, the reactor was taken out, and the conventional The centrifugation method is used for separation, and the obtained solid product is washed with distilled water to neutrality, and the copper zirconium phosphate product is obtained after air-drying at room temperature.

Embodiment approach 2

[0014] Take 3.4mL of zirconium oxychloride solution with a concentration of 1.0mol / L and 1.7mL of a copper acetate solution with a concentration of 4.0mol / L, mix and stir evenly, add 1.7mL of phosphoric acid solution with a mass percentage of 85%, and adjust the pH value to 1.2, and after 10 minutes of stirring evenly, seal the obtained blue gel into a polytetrafluoroethylene-lined reactor, put the reactor in an oven at 180°C, and crystallize for 72 hours, then take out the reactor. The conventional centrifugation method is adopted for separation, and the obtained solid product is washed with distilled water until neutral, and air-dried at room temperature to obtain a copper zirconium phosphate product.

Embodiment approach 3

[0016] Take 1.0 mL of zirconium nitrate solution with a concentration of 4.0 mol / L and 12.0 mL of a copper chloride solution with a concentration of 1.0 mol / L, mix and stir evenly, add 1.1 mL of phosphoric acid solution with a mass percentage of 85%, and adjust the pH value to 1.8, after 10 minutes of stirring evenly, seal the obtained blue gel into a polytetrafluoroethylene-lined reactor, put the reactor in an oven at 220°C, and crystallize for 24 hours, take out the reactor, and use The conventional centrifugal separation method is used for separation, and the obtained solid product is washed with distilled water until it is neutral, and then air-dried at room temperature to obtain a copper-zirconium phosphate product.

Abstract

The invention discloses a preparation method and an application method of a CuZr(PO4)2*4H2O material, and belongs to the field of inorganic functional materials. The preparation method and the application method are characterized in that the CuZr(PO4)2*4H2O material is directly prepared by a hydrothermal synthesis method, and further applied to the field of lubrication. The preparation method comprises the steps that one of a zirconium oxychloride solution and a zirconium nitrate solution with a molar concentration of 1.0-4.0mol / L is mixed with one of a copper chloride solution, a copper acetate solution and a copper nitrate solution with a molar concentration of 1.0-4.0mol / L on the condition that a molar ratio of Cu to Zr is 0.8-3.0, and stirred uniformly; then a pH value of a system is adjusted to be 0.5-5 with 85% of phosphoric acid solution by mass percent; stirring is conducted for 10-20min; blue gel is obtained, sealed in a polytetrafluoroethylene lining reaction kettle, and crystallized in a drying oven at 100-220 DEG C for 12-200h; a product is washed to be neutral with distilled water by a centrifuge, and dried at a room temperature; and the CuZr(PO4)2*4H2O material is obtained. The material is directly added to lubricant base oil to serve as a lubricant additive in an ultrasonic, heating and stirring, or three-roller grinding mode, and has good bearing capability, abrasion resistance and antifriction capability.

Description

technical field [0001] The invention relates to a method for preparing and applying a copper-zirconium phosphate material, which belongs to the field of inorganic functional materials, and specifically relates to a method for directly preparing a copper-zirconium phosphate material by a hydrothermal synthesis method and further applying the prepared material to the lubrication field. Background technique [0002] Zirconium phosphate crystal materials have attracted widespread attention due to their excellent properties in ion exchange, adsorption, and catalysis. In grease lubrication research, it was found that copper zirconium phosphate (CuZr(PO 4 ) 2 4H 2 O) The material exhibits excellent lubricating properties. Under the same research system, the copper zirconium phosphate material is better than the most widely used inorganic lubricant molybdenum disulfide (MoS 2 )good. At present, copper zirconium phosphate materials are all prepared by ion exchange method, mainly ...
