Problems solved by technology

The process is complicated, the reaction time is long, and the efficiency is low, and cardanol only replaces part of tung oil, and the cost reduction is limited
[0005] In addition, because tung oil has a long-chain structure, its molecular formula contains two double bonds, while the molecular structure of cardanol has a benzene ring on one side, with only one double bond, so the network structure formed after the reaction of cardanol is more complex than that formed after the reaction of tung oil. There is less mesh structure, which reduces the hardness and flexibility of the product, causing the worthwhile copper clad laminate to crack easily when punching holes, seriously affecting product quality

Abstract

The invention relates to a production method for cardanol modified phenolic resin, wherein the method comprises the following steps: 1, preparing modified phenolic resin solution, the raw materials for preparing the modified phenolic resin solution based on mass parts proportioning are as follows: 150-210 parts of phenol, 148-185 parts of cardanol, 230-260 parts of formaldehyde, 0.1-2.3 parts of triethylamine, 2.0-4.2 parts of ammonia water and 350-400 parts of methanol, wherein when preparing, adding the phenol, cardanol, formaldehyde, triethylamine and ammonia water based on the proportioning into a reaction kettle to react, and adding methanol as dissolvent to prepare phenolic resin solution; 2, preparing modified phenolic resin composite: taking 100 parts of phenolic resin solution and adding 11-18 parts of silicon micro-powder and 10-15 parts of epoxidized soybean oil into the solution, and fully mixing them to obtain the finished product. The invention is characterized by simple technology and low production cost. The prepared copper-clad plate has good flexibility.

Description

technical field [0001] The invention relates to a production method of cardanol-modified phenolic resin, which is mainly used in the field of copper-clad laminate production. Background technique [0002] Copper-clad laminate is a plate material made by impregnating electronic glass fiber cloth or other reinforcing materials with resin, covering one or both sides with copper foil and hot pressing. It is called copper-clad laminate (Copper-clad laminate) Clad Laminate, CCL), referred to as copper clad laminate. [0003] Copper clad laminate is an extremely important basic material for printed circuit boards. Printed circuit boards of various forms and functions are selectively processed, etched, drilled and copper-plated on copper clad laminates. Different printed circuits (single-sided, double-sided, multilayer). As the substrate material in the manufacture of printed circuit boards, copper clad laminates mainly play the role of interconnection, insulation and support for ...
