Problems solved by technology

At the same time, in order to reduce the risk of fire in electronic products and ensure the safety of customers, copper-clad laminates in the traditional field mainly introduce halogen elements into the resin, the most common being bromide, such as brominated epoxy resin, etc., however, resulting in halogen-containing When electronic products are burned, they will release harmful substances such as hydrogen halides and aromatic compounds, and the amount of smoke is large. At the same time, waste electronic products also have environmental pollution and the risk of affecting human and animal health.

Abstract

The invention relates to the technical field of flame-retardant processing, in particular to an environment-friendly composite flame retardant special for a copper-clad plate and a preparation methodthereof. The composite flame retardant comprises a synergistic flame retardant, magnesium hydroxide and aluminum hydroxide, wherein the magnesium hydroxide is superfine modified magnesium hydroxide; the aluminum hydroxide is superfine modified aluminum hydroxide; the mass ratio of the synergistic flame retardant, the superfine modified magnesium hydroxide and the superfine modified aluminum hydroxide is 1: (3-14): (2-8). The composite flame retardant special for the copper-clad plate has high cost performance, is environment-friendly and non-toxic, and can improve the flame retardant propertyand mechanical property of the copper-clad plate.

Description

technical field [0001] The invention belongs to the technical field of flame retardant processing, in particular, the invention relates to a special environment-friendly composite flame retardant for copper clad laminates and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, the electronic information industrialization revolution represented by computers and electronic products has penetrated more and more into various fields of social development. As the functions of such electronic products become more and more powerful, the quality and reliability of The requirements are getting higher and higher, resulting in higher requirements for copper clad laminates and prepregs for printed circuit boards. At the same time, in order to reduce the risk of fire in electronic products and ensure the safety of customers, copper-clad laminates in the traditional field mainly introduce halogen elements into the resin, the mos...
