Abstract

The invention relates to a pretreatment method for chemical plating electric conducting and magnetic conducting glass fibre, which has the characteristics that: alkali-free glass fiber undergoes ultrasonic dispersion and cleaning, is washed by stilled water and then undergoes dispersion treatment, roughening treatment, coupling treatment, sensitizing and activating treatment, peptization treatment and oven drying treatment. The method has the advantages that: firstly, the self-made activator is adopted to complete the sensitizing and activating in one step and has the effect better than the two-step method, thereby optimizing the pretreatment process; secondly, the combined coupling agent is used to strengthen the glass fibre and the chemical adsorption capacity of Pa <2+> in the activator, thereby the coating has good combination property.

Description

technical field [0001] The invention relates to a pretreatment method for chemically plated conductive and magnetic glass fibers. The alkali-free glass fibers are pretreated with an activation solution, a dispersion solution, a roughening solution, a coupling solution, and the like. Background technique [0002] Electroless glass fiber can be applied in many fields. For example, it can be used in electromagnetic shielding materials, antistatic composite materials, electric heating materials, stealth composite materials, coatings and fillers of various conductive materials, etc. [0003] In the process of preparing conductive glass fibers, the effect of glass fiber pretreatment directly affects the coating performance of conductive glass fibers. The key to electroless plating on non-metallic materials is the pretreatment method used to enable the surface of the non-metallic substrate to obtain catalytic activity to induce the occurrence of electroless plating reactions.
