Problems solved by technology

Phenolic resin is a synthetic resin that was first discovered and produced industrially, but at present, modified phenolic resin has poor heat resistance, and paper-based copper clad laminates prepared with modified phenolic resin have poor heat resistance and flame retardancy. And other problems, it can no longer meet the heat resistance and thermal stability requirements of the printed circuit copper clad laminate in the era of lead-free soldering

Abstract

The invention provides glue liquor for a flame-retardant paper-based copper-clad laminate, the flame-retardant paper-based copper-clad laminate and preparation methods of the glue liquor and the flame-retardant paper-based copper-clad laminate. The glue liquor for the flame-retardant paper-based copper-clad laminate is prepared from, by weight, epoxidized soybean oil-modified phenolic resin, epoxy resin, a flame retardant and an organic solvent, wherein the epoxidized soybean oil-modified phenolic resin is prepared from, by weight, 1,200-1,600 parts of epoxidized soybean oil, 500-700 parts of phenol, 1,000-1,300 parts of bisphenol A, 5-10 parts of 2-methylimidazole, 800-1,200 parts of formaldehyde, 60-150 parts of a basic catalyst, 2,500-3,000 parts of a solvent, 5-60 parts of graphene and 5-40 parts of graphene oxide. The copper-clad laminate is simple in preparation process, capable of saving energy and low in cost and has the good punching property, soldering resistance, flame retardance and processability.

Description

technical field [0001] The invention belongs to the technical field of production methods of copper-clad laminates, and in particular relates to a glue solution for flame-retardant paper-based copper-clad laminates, a flame-retardant paper-based copper-clad laminate and a preparation method thereof. Background technique [0002] Paper-based copper clad laminates are one of the main varieties of copper clad laminates, and are widely used in household electronic products such as TVs. During its production and use, safety and reliability are important standards for products. According to statutory requirements, the flame retardancy of paper-based copper-clad laminates used in some electronic products must reach the UL94V-0 level. At present, phenolic resins modified by bio-oils such as tung oil and phosphates have been added for flame retardancy, which has attracted people's attention. Phenolic resin is a synthetic resin that was first discovered and produced industrially, bu...
