NOVELTY - Glass fiber cloth reinforced thermosetting copper-clad plate comprises a glass fiber cloth, and the copper foil bonded with resin adhesive on one or both sides of the glass fiber cloth, where the resin adhesive is formed by mixing adhesive and flame retardant, and the surface of the copper foil is coated with a coating including 70-80 pts. wt. polyetherimide and 25-50 pts. wt. additive. USE - Used as glass fiber cloth reinforced thermosetting copper-clad plate. ADVANTAGE - The copper-clad plate: uses the resin adhesive to bond the copper foil on one side or upper and lower sides of the glass fiber cloth, adds the flame retardant on the basis of the original resin adhesive, which is the pyridine solution of phenol and phosphorus oxychloride for reacting, thus obtain the halogen-free flame retardant, adds halogen-free flame retardant to improve the flame retardant property of the product, can ensure the safety of use and reduce the effect of the damage to the environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the glass fiber cloth reinforced thermosetting copper-clad plate, comprising (ii) dissolving the phenol in the solvent, stirring uniformly, cooling, adding phosphorus oxychloride, stirring, refluxing and heating, after finishing reaction, cooling, water washing and recycling solvent, centrifuging, adding sodium sulfate, filtering, and distilling to obtain the flame retardant; (ii) preparing the recovered product by (ii-a) dissolving the recycling solvent in water, adding hydrogen bromide, stirring uniformly, heating, adding hydrogen peroxide, heating, after finishing reaction, reducing temperature and extracting to obtain product A, (ii-b) dissolving the product A in the organic solvent, placing into a sealed reactor, adding catalyst, ammonium hydroxide, potassium carbonate, heating, after finishing reaction to obtain the recovered product; and (iii) preparing the copper-clad plate by (iii-a) mixing the additive and polyetherimide, stirring uniformly, heating, adding recycling product, stirring uniformly, continuously reacting, after finishing reaction to obtain coating material, (iii-b) coating the coating material on the surface of the copper foil, and drying to obtain the copper foil coated with coating and (iii-c) mixing the adhesive and flame retardant, spraying on the surface of the copper foil coated with the coating, placing on one side or two sides of the glass fiber cloth, then irradiating by ultraviolet, and placing in the vacuum hot press to press to obtain the copper-clad plate.
