The invention provides a microemulsion preparation taking rosin-based vegetable oil as a solvent and a preparation method thereof, and relates to a pesticide preparation. The microemulsion preparation consists of the following raw materials in percentage by mass: 0.5 to 30 percent of pesticide active ingredients, 55 to 20 percent of emulsifier, 0 to 8 percent of cosolvent, 0.1 to 0.3 percent of defoamer, 1 to 30 percent of rosin-based vegetable oil, and the balance of water. The preparation method comprises the following steps of: adding the pesticide active ingredients, the rosin-based vegetable oil, the cosolvent, emulsifier and the defoamer into a reaction kettle, performing cutting and uniform dispersion at 2,000 to 5,000 rpm / min, and adding the balance of water into the mixture for high-speed cutting to obtain the microemulsion preparation taking the rosin-based vegetable oil as the solvent.

The invention provides a nickel colloidal catalyst solution for electroless nickel plating or nickel alloy. After immersing a non-conductive substrate in a liquid containing a surfactant and performing an adsorption promotion treatment in advance, use a catalyst solution containing (A) a soluble nickel salt, (B) Electroless nickel plating of reducing agent and (C) colloidal stabilizer A nickel colloidal catalyst solution is used to provide a catalyst to a non-conductive substrate, and then perform electroless nickel plating. After the catalytic activity is enhanced by the adsorption-promoting pretreatment, a catalyst solution with excellent temporal stability is used for catalyst application, and then electroless plating is performed, so that a uniform nickel coating without color spots can be obtained. Even if it is used as a nickel alloy plating method instead of the above-mentioned nickel plating method, a nickel alloy film having excellent uniformity can be obtained.
