| titleOfInvention | A kind of non-cyanide pre-plating copper plating solution and preparation method thereof |
| abstract | The present invention relates to a kind of non-cyanide pre-plating copper plating solution and preparation method thereof, the electroplate liquid is comprised the following components in percentage by weight：Chelating agent 1～60%, mantoquita 0.5～30%, balance of water, the formula of the chelating agent is M x H y P n O 3n+1 R z , wherein M is any one or more in alkali metal ion and NH4+, and R is acyl group, and the formula of mantoquita is Cu x/2 H y P n O 3n+1 R z , x, n and z be positive integer, and y is 0 or positive integer, x+y+z=n+2.Preparation method is as follows：（1）The preparation of chelating agent：By the hybrid reaction in molar ratio of the acid salt containing the alkali of M, carbonate or bicarbonate and phosphoric acid, the unitary organic acid containing R bases or multicomponent organic acid, then reactant liquor 0.5～10h of one-step polymerization acquisitions chelating agent finished product under the conditions of 100～800 DEG C；（2）The preparation of mantoquita：Chelating agent is mixed homogeneously in aqueous phase system in molar ratio with cupric compound, reacts 0.5～1h in 25～100 DEG C, reaction terminate after through centrifugation and dry mantoquita；（3）The preparation of electroplate liquid：Each component is mixed in proportion, electroplate liquid is obtained. |
