Problems solved by technology

[0005] The existing SBID powder surface treatment method has the following disadvantages: 1. The SBID powder is prone to agglomeration in the solution, thereby affecting the final coating effect; 2. The coated powder is also prone to agglomeration during the drying process , and even subsequent grinding and other treatments are required, which not only easily introduces impurity ions, but also may damage the coating layer, affecting the compatibility of SBID powder with non-metallic materials (especially polymers), thereby affecting the resistance of polymer products.

preparation example 1-9

[0096] It is used to illustrate the surface treatment method of the inorganic powder of the present invention.

preparation example 1

[0098] 2.5kg of boric acid (in B 2 o 3 1.4kg) and 200L absolute ethanol are placed in the evaporator 10 for dissolution; Cu 3 (PO 4 ) 2 Powder (purchased from Xilong Chemical Co., Ltd., green) takes 50 kg and pours it into the tank body 11 of the evaporation tank 10, raises the tank body 11 to combine with the sealing cover 13 to form a sealed evaporation tank 10, and starts stirring 20 (stirring speed is 150r / min), ultrasonic oscillator (oscillating frequency is 28KHZ, power 1000W), condenser 31, so that the mixed system in the evaporation tank 10 is subjected to the effect of mechanical stirring and ultrasonic oscillation at the same time, and simultaneously sends water to the evaporation tank 10 The hot water of 95°C is introduced into the thermal insulation jacket to make the temperature in the evaporation tank 10 reach the range of 83-93°C, and the anhydrous ethanol in the evaporation tank 10 is heated and evaporated, condensed in the condenser 31 and recovered to the ...

preparation example 2

[0100] The surface treatment method of inorganic powder: with reference to Example 1, the difference is that

[0101] (1) 13.32kg of boric acid (in B 2 o 3 7.5kg) and 200L absolute ethanol are placed in the evaporator 10 for dissolution; Cu 3 (PO 4 ) 2 Powder (purchased from Xilong Chemical Co., Ltd., green) gets 50kg and pours it into the tank body 11 of the evaporation tank 10;

[0102] (2) The stirring speed of the agitator 20 is 200r / min, the oscillation frequency of the ultrasonic oscillator is 28kHz, and the power is 1000W, and the hot water of 95°C is passed into the thermal insulation jacket of the evaporator 10 to make the temperature in the evaporator 10 Reach the range of 83-93°C;

[0103] The resulting surface-treated (boron-coated) Cu 3 (PO 4 ) 2 Powder (particle size D 50 4.2 μm, D 90 9.5 μm), this product is recorded as P2.

Abstract

The invention discloses an inorganic powder surface treatment method, a chemical plating activating agent, a polymer product and a surface selective metalizing method of the polymer product. The inorganic powder surface treatment method comprises the following steps: inorganic powder and a surface treatment agent dissolved in a dispersing agent are mixed to form a mixed system; and under the conditions of heating and stirring, the dispersing agent in the mixed system is evaporated and recovered to obtain surface-treated inorganic powder. The inorganic powder surface treatment method recovers the dispersing agent during stirring and dispersing, so that the distribution of the inorganic powder and the surface treatment agent is more uniform; and the method can prevent the agglomeration phenomenon, so that the surface-treated inorganic powder needs no further grinding, impurity ions introduced by such treatments as grinding can be effectively prevented, the compatibility between the surface-treated inorganic powder and a polymer matrix is improved, and the impact strength of the polymer product is improved.
