Plastic based foam metalizing method

Abstract

The invention provides a method for metalizing plastic base foam, which relates to a coat made of organic materials. The method is achieved through the following steps: plastic base foam is submerged in low temperature heat curing polymer silver paste or the low temperature heat curing polymer silver paste is sprayed to the plastic base foam so that the fiber of the plastic base foam is attached with a conducting layer; the plastic base foam and the low temperature heat curing polymer silver paste are thermally cured for thirty to sixty minutes at the temperature of 120 DEG C to 180 DEG C, thus forming a foam metalized layer. The silver paste consists of 30 to 60 percent of silver powder, and 70 to 40 percent of organic carriers. The silver powder is flaky silver powder. The organic carriers consist of 5 to 15 percent of viton resin, 1 percent of an adhesion accelerant N742, 5 to 15 percent of dibutyl phthalate and 69 to 89 percent of butyl acetate. By adopting the method for metalizing plastic base foam provided by the invention, the foam plastic can be metalized well inside; after the metalized foam plastic is electroplated, the plastic base foam can be manufactured into foamed metal grid plates which are capable of carrying current and become foam base lead-acid accumulator plate grid electrodes.

Description

technical field [0001] The patent of the present invention relates to the process of plastic coating, in particular to the coating process of organic materials, specifically, it belongs to the metallization method of plastic-based foam. Background technique [0002] Metal foam is a functional material developed in recent years. It is widely used in foam electrode materials. With the increasing shortage of global oil resources, the research on making metal foam into grid electrodes for energy storage batteries is becoming more and more extensive. Plastic-based foam is a material based on plastic foam. The traditional method of plastic metallization is electroless plating, such as Chinese Patent No. 99815493.8 "Method of Plating Metal on Plastic Surface", 200610132412.6 "Plastic Surface Treatment Process", etc. These processes require tedious pretreatments such as activation and sensitization, but foam The plastic structure is loose and the interior is porous.

The traditional method of plastic metallization is electroless plating, such as Chinese Patent No. 99815493.8 "Method of Plating Metal on Plastic Surface", 200610132412.6 "Plastic Surface Treatment Process", etc. These processes require tedious pretreatments such as activation and sensitization, but foam The plastic structure is loose and the interior is porous

It can be seen that metallization cannot be well achieved inside the foam plastic by means of electroless plating.
