Study Of Electroless Plating Based On Raw Lacquer Surface

Lacquer is natural polymer. Urushiol is principal component of lacquer. According to its special structure characteristic, Lacquer is a kind of nonmetal material. Easily obtaining the film of PUF, Urushiol formaldehyde condensation polymer(PUF) has been prepared first. Electroless plating research has been prepared on PUF. Based on optimizing process and prescriptions of different chemico-plating, a series of electroless plating research has been prepared on Lacquer and cardanol formaldehyde condensation polymer(PC).By treating on lacquer, PUF and PC surface with similar method, nickel, copper, silver and lead dioxide coatings have been obtained. Systemic tests are to measure the binging strength of three polymer materials, and anticorrosive properties. The properties of coatings are studied by IR, DMTA, TG-DSC, XRD, SEM etc. The results show that the properties of deposits are excellent and good binging strength. Nickel coating is high-phosphorous. The tan 6 of polymer films with deposit is lower and the range of the Tg peak becomes wider. The thermal stability is distinctly improved. Furthermore, Nickel coating possesses anticorrosive properties especially alkali corrosion property.Lacquer reacts with metal compounds by coordination reaction, which can obtain urushiol-metal polymer. In order to acquire other lacquer-metal material, this paper carries out metallization treating on lacquer surface with electroless plating method, and bright coatings of nickel, copper, silver or lead dioxide has been prepared. It is important to improve the art appreciation worth of lacquer articles, endow the new property for lacquer polymer and benefits to enlarge its utilization aspects in the future.
