Problems solved by technology

Halogen flame retardant has become the mainstream of the market due to its low dosage, high flame retardant efficiency and wide application range. However, it also produces a large amount of corrosive and toxic gases, which greatly limits its application.
At present, most of the flame retardants used for epoxy resin are phosphorus-containing flame retardants, which have the characteristics of low halogen, halogen-free, low toxicity, low dosage and high efficiency, and have attracted much attention in the field of flame retardants, but Phosphorus-based flame retardants have a large amount of smoke and are inherently toxic. They are liquid at room temperature and can leak out from the waste, thereby polluting the substrate.

Description

Technical field: [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly epoxy resin adhesive. Background technique: [0002] Epoxy resin adhesive is known as "universal glue". It has been developed since the end of the 19th century and the beginning of the 20s, and has a history of more than 100 years. It is an adhesive with relatively mature preparation technology and excellent mechanical properties. However, in addition to excellent mechanical properties, modern adhesives also require good corrosion resistance, environmental protection, non-toxic and harmless, and more importantly, good flame retardancy, so as to protect people's lives to the greatest extent. Property security. [0003] The most commonly used method to improve the flame retardancy of epoxy resin glue is to add an appropriate amount of flame retardant. my country's flame retardant science started late, and mainly halogenated flame retardants, accounting...
