Description

technical field [0001] The invention belongs to the field of preparation of phenolic resins, and in particular relates to a high-performance nitrogen-containing phenolic resin and a preparation method thereof. Background technique [0002] With the advent of the information age, electronic components have entered a new stage of high integration and high reliability. Installing their necessary substrates - printed circuit boards have become an indispensable and important component of most electronic products. As a printed circuit board The main substrate material in manufacturing, the copper clad laminate plays three main functions of conduction, insulation and support, the physical properties, processability and cost of the printed circuit board mainly depend on the substrate material, depending on the matrix resin used, the copper clad laminate can be Divided into phenolic resin base, epoxy resin base, polyester base and polyimide base and other types. [0003] The resin f...

Problems solved by technology

[0003] The resin formed by polycondensation of phenols and aldehydes is called phenolic resin. Because of its rich source of raw materials, low price and simple production process, its products have excellent mechanical properties, heat resistance, dimensional stability, flame retardancy and Low smoke; therefore, it is widely used in the fields of electrical appliances and electronics. Due to the unstable synthesis process of traditional nitrogen-containing phenolic resin, the nitrogen content of the polymer is low, and the flame retardancy is not good. It is often necessary to add inorganic flame retardants for synergistic Flame retardant can achieve the ideal flame retardant performance, and excessive addition of inorganic flame retardants will lead to a decrease in its mechanical properties and unsatisfactory overall performance. A simple and convenient operation process has been developed, it is easier to control the reaction end point, and the reaction temperature is moderate. The productive rate of polymer is higher, and the higher phenolic resin of nitrogen content is the problem that those skilled in the art need to solve urgently
