Problems solved by technology

[0002] At present, polymer materials such as epoxy resin, polyester and engineering plastics are widely used in national economic construction, especially epoxy resin, as an important thermosetting material, is based on its excellent electrical insulation performance, corrosion resistance and adhesion. It is widely used in electronic appliances, engineering building materials, home furnishings and other fields. However, polymer materials themselves do not have fire and flame retardant properties. Ordinary epoxy resins are highly flammable. Once ignited, it is difficult to Self-extinguishing and accompanied by flame-drops, it is easy to ignite combustibles around and in low altitudes, causing the fire to spread and causing great harm to the safety of people's lives and property.
