Biobased resin composition, metal foil-clad laminate, and printed wiring board

Abstract

The invention provides a bio-based resin composition, a metal foil-coated laminated board and a printed circuit board, and relates to the technical field of thermosetting resin. The bio-based resin composition comprises the following components in parts by weight: 5-40 parts of bio-based resin with an allyl structure, 30-80 parts by weight of modified polyphenylene ether resin and 1-20 parts by weight of a cross-linked curing agent containing unsaturated double bonds, wherein the sum of the three substances is 100 parts by weight. According to the bio-based resin composition provided by the invention, the bio-based resin with an allyl structure is used as a raw material, so that the bio-based resin composition not only has excellent photo-curing property, but also is mild in reaction condition, does not need to add a polymerization inhibitor, and has good resin compatibility and flowability; meanwhile, a prepared insulating layer can be biodegraded, so that the environmental pollutionis effectively reduced; the bio-based resin is derived from organisms and can be regenerated and recycled, so that the energy pressure is effectively relieved, and the market prospect is wide.

Description

technical field [0001] The invention relates to the technical field of thermosetting resins, in particular to a bio-based resin composition, a metal foil-clad laminate and a printed circuit board. Background technique [0002] With the rapid development of electronic communication equipment and consumer electronics in the 5G era, especially the replacement of smart mobile terminals, there is a large demand for raw materials, which usually come from non-recyclable resources such as petroleum, and the electronic material waste produced is difficult Biodegradable, not recyclable. [0003] Therefore, with the increasingly prominent environmental and energy issues, the development of environmentally friendly bio-based polymer materials, especially bio-based thermosetting resins, is of increasing significance. [0004] In view of this, the present invention is proposed. Contents of the invention [0005] One of the objectives of the present invention is to provide a bio-based ...
