Abstract

The invention discloses a bonding agent for electronic ceramic molding, which comprises the following raw materials in percentage by weight: 7.31-10.12 percent of polyvinyl butyral, 1.69-3.37 percent of polyethylene glycol-400, 3.09-4.21 percent of dibutyl phthalate, 0-0.56 percent of deep sea refined fish oil, 54.49-58.61 percent of toluene, and 27.25-29.3 percent of isopropanol, wherein the total weight percentage of the components are 100 percent. The invention also discloses a preparation method of the bonding agent, comprising the steps of: weighing the raw materials, sequentially loading the polyvinyl butyral, the polyethylene glycol-400, the dibutyl phthalate, the deep sea refined fish oil, the toluene, and the isopropanol into a nylon ball-milling tank, processing with a ball-milling process, injecting into a container and standing for defoaming to prepare the bonding agent. The prepared bonding agent has good stability, high transparency, large viscosity, and cost reduction.

Description

technical field [0001] The invention belongs to the technical field of adhesive materials, and relates to an adhesive for forming electronic ceramics, and also relates to a preparation method of the adhesive. Background technique [0002] Adhesive is an additive used in the molding process of materials or products to help the molding effect. Adhesives are often composed of multiple components, but there are three basic functional components, namely main materials, additives and solvents. There are many kinds of main materials that can be used as adhesives, generally high polymers, such as polyvinyl alcohol, polyvinyl formal, etc.; additives are generally added to enhance the adhesive and its use system. Reagents with plasticizing effects, such as aromatic esters, polyglycols, etc.; the function of the solvent is to dissolve all materials, and the main material and additives determine the type and amount of the solvent. General organic solvents can be used as solvents for a...
