Problems solved by technology

In recent years, EU experts have pointed out that when the halogen-based flame retardants in copper-clad laminates are heated and decomposed naturally, some halogen-containing substances (such as polybrominated biphenyls and polybrominated diphenyl ethers) will produce trace amounts of volatile harmful gases ; In addition, lead-containing solder in circuit board products is easy to form lead pollution when electronic products are disposed of, and the waste disposal of a large number of electronic products will cause environmental pollution and endanger human health

Embodiment

[0050] The resin composition of this embodiment includes phosphorus-containing epoxy resin, tung oil modified phenolic resin, nitrogen-containing phenolic resin, curing agent, and curing accelerator; phosphorus-containing epoxy resin is formed by the reaction of epoxy resin and organic phosphorus compound According to the weight ratio, the phosphorus content is 8-12%; the nitrogen-containing phenolic resin refers to the phenolic resin modified by the amine compound, and the amine compound can be melamine. According to the weight ratio, the nitrogen-containing phenolic resin has a nitrogen content of 4-6 %; The amount of curing agent and curing accelerator is equivalent to 0.2-0.4 equivalent of the epoxy group of the epoxy resin.

[0051] Flame retardant mechanism and selection of flame retardant:

[0052] The metaphosphoric acid produced by phosphorus-containing compounds during combustion has the functions of dehydration, cross-linking and carbon formation. The generated car...

Abstract

The invention discloses an environment-protective resin composition and environment-protective high-dip-soldering proof flameproof paper backing copper covering board in the copper covering board manufacturing technical domain, which is characterized by the following: adding flameproof agent without halogen such as nitrate, phosphate and so on into modified phenol resin; making the environment-protective resin to form semi-solidifying piece through dipping paper of resin composition; overlapping several semi-solidifying piece to press under certain temperature and pressure to obtain the product to satisfy the request of European environment protection order and non-lead reflux welding need.

Description

1. Technical field: [0001] The invention relates to an environment-friendly resin composition and a method for using the resin composition to produce an environment-friendly high-dipping resistance and flame-retardant paper-based copper-clad laminate, belonging to the technical field of copper-clad laminate production methods. 2. Background of the invention: [0002] Copper Clad Laminate (Copper Clad Laminate, CCL for short) is widely used in the manufacture of printed circuit boards (PCB for short) used in various household appliances, electronic information products and industrial electronic products. As the substrate material of printed circuit boards, it plays the three major functions of carrying electronic components, forming conductive circuit patterns, and insulating between layers and lines. It is an important electronic basic material. [0003] Flame retardant performance is an important safety indicator of CCL and its end products. Halogen flame retardant material...
