AI Technical Summary
When used for bonding metal three-dimensional plates, the flame retardant performance does not meet the requirements, and the bonding strength is insufficient, resulting in the mechanical properties and service life of the three-dimensional plates not meeting the requirements.
The adhesive film arranged in sequence is adopted, including a first adhesive layer, a glass fiber layer and a second adhesive layer. By introducing components such as ethylene-vinyl acetate copolymer, thermoplastic elastomer and magnesium hydroxide into the adhesive layer, and chemical grafting is used in the glass fiber layer to improve the flame retardant performance and bonding strength of the adhesive film.
It realizes the high flame retardant performance and excellent bonding performance of metal three-dimensional boards, which can meet the use requirements in civil construction and vehicle and ship decoration, and at the same time reduces the combustion heat value and improves the overall strength of the material.
