Abstract
The utility model discloses a reaction kettle for silver-coated copper powders used for preparing electronic pastes. The reaction kettle comprises a kettle body (1), a motor (2), a stirring shaft (3), stirring paddles and a liquid storage pot (4), wherein a dispersing device is arranged inside the kettle body (1); the dispersing device comprises a sealed accommodation body (9-1), an ultrasonic wave vibrator (9-2), a bracket (9-3) and a sleeve (9-4); the liquid storage pot (4) is connected with a liquid dripping ring (10) which is provided with a plurality of liquid dripping holes; the stirring paddles comprises a radial flow type stirring paddle (12) and a push flow type stirring paddle (13); and the inner wall of the kettle body (1) is high in flatness. By adopting the reaction kettle, prepared silver-coated copper powder particles are more uniform in size, the copper can be completely coated by the silver, the dispersity among the silver coated copper powders is high, and the silver-coated copper powders are not easy to gather.
Description
Technical field
The utility model relates to a kind of chemical plating equipment, is specifically related to a kind of agitated reactor of electric slurry with silver-coated copper powder that be used to prepare.
Background technology
For guaranteeing uniformity, continuity and the thin layerization of the rete that electric slurry finally makes, its donor electron slurry is generally had following requirement with silver-coated copper powder: 1. uniform particles, coverage degree is high; 2. polymolecularity does not produce gathering as far as possible between the particle; 3. excellent conductivity; 4. purity is high, and impurity content is low as far as possible.
The prior art for preparing electric slurry is employed in the method for carrying out chemical plating in the agitated reactor more with silver-coated copper powder at present; Agitated reactor comprises structures such as kettle, motor, shaft, paddle, fluid reservoir; The copper simple substance of complexing agent complexing is placed in the kettle as reducing solution; Silver ammino solution is placed in the fluid reservoir, silver ammino solution is added drop-wise in the reducing solution with certain speed, realize that silver coats the copper process.But there is following shortcoming in this prior art: reducing solution is difficult in the agitated reactor is uniformly dispersed; The too high phenomenon of local saturation appears easily; Thereby it is inhomogeneous to cause in silver ammino solution dropping process silver ammino solution and reducing solution to mix, thus the electric slurry that makes formation with silver-coated copper powder particle size heterogeneity, silver coating copper is incomplete; Bad dispersibility between silver-coated copper powder is prone to assemble.
The utility model content
The utility model technical problem to be solved is the deficiency to above prior art; A kind of agitated reactor of electric slurry with silver-coated copper powder that be used to prepare is provided; Use silver-coated copper powder particle size that this agitated reactor prepares than homogeneous; It is complete that silver coats copper, dispersed high between silver-coated copper powder, is difficult for assembling.
For addressing the above problem; The utility model provides a kind of agitated reactor of electric slurry with silver-coated copper powder that be used to prepare; Comprise kettle, motor, shaft, paddle, fluid reservoir; Be provided with dispersal device in the said kettle; Dispersal device comprises sealing accommodating body that the Stainless Steel light sheet material processes, place ultrasonic oscillator in the sealing accommodating body, will seal support that accommodating body is fixed to kettle, will control the sleeve pipe that control circuit that ultrasonic oscillator vibrates picks out kettle, and control circuit picks out from kettle top through sleeve pipe and is connected with the ultrasonic wave controller.
After adopting above structure; The utility model compared with prior art has the following advantages: dispersal device is set in the kettle, and the ultrasonic wave that the ultrasonic oscillator vibration produces in the dispersal device makes being evenly dispersed property of reducing solution in the agitated reactor; The too high situation of reducing solution local saturation can not appear; Thereby it is more even that the silver ammino solution that drips is mixed with reducing solution, and the silver-coated copper powder particle size of formation is than homogeneous, and silver coating copper is complete; Silver coats and makes the silver-coated copper powder that forms dispersed each other high fully again, is difficult for assembling.
Said fluid reservoir is connected with the dropping liquid ring that is provided with several dripping holes, and said dropping liquid ring is positioned at position, middle, kettle top, is connected through pipeline between fluid reservoir and the dropping liquid ring and is provided with shutoff valve.Join the rate of addition of kettle through silver ammino solution in the dropping liquid ring control fluid reservoir, thereby make the particle diameter homogeneous more of the silver-coated copper powder of formation.
Said paddle comprises radial-flow type paddle and pulling flow type paddle, and wherein the pulling flow type paddle is positioned at shaft bottom, and the radial-flow type paddle is positioned at the top of pulling flow type paddle.The pulling flow type paddle will be deposited on the high saturation reducing solution dispersed with stirring of agitated reactor kettle bottom and open, and then the stirring of the radial-flow type paddle through being positioned at pulling flow type paddle top makes the reducing solution of whole kettle more even.
Said inner wall of kettle is the high-flatness inwall.The silver that the high-flatness inwall makes silver ammino solution and reducing solution reaction generate is difficult for being attached to inner wall of kettle and has avoided causing unnecessary waste.
