NOVELTY - Preparing flame-retardant and aging-resistant cover plate comprises (a) uniformly mixing pentaerythritol phosphorus oxychloride and chloroform, stirring and reacting, filtering and collecting the product, performing vacuum, and drying flame retardant intermediate, taking p-hydroxybenzaldehyde, adding the amino graphene, continuously reacting for 6-8 hours, washing with ethanol, collecting product to obtain the oxidized graphene flame retardant, (b) taking polyester polyol, glycerol, triethanolamine, foaming agent dibutyltin dilaurate, oxidized graphene flame retardant titanium dioxide and deionized water, and stirring to obtain the polyurethane foaming liquid, and (3) taking the honeycomb paper and the glass fiber felt, stacking and placing the glass fiber felt, honeycomb paper and glass fiberfelt in order to form framework, spraying polyurethane foaming liquid on two sides of the framework, and pressing and forming in the mold to obtain the finished product. USE - The cover plate is useful for automobile luggage box, and separating spare tire storehouse and luggage. ADVANTAGE - The cover plate has excellent anti-ultraviolet aging performance, and has high application. The prepared box of the prepared boot is light weight, air taste, flame retardant performance index satisfy the requirement. The polyurethane foaming layer component bonding force is improved, so that the mechanical property of the cover plate is further improved. DETAILED DESCRIPTION - Preparing flame-retardant and aging-resistant cover plate comprises (a) uniformly mixing pentaerythritol phosphorus oxychloride and chloroform, stirring and reacting at 70-80degrees Celsius for 8-9 hours, filtering and collecting the product, performing vacuum, and drying flame retardant intermediate, taking p-hydroxybenzaldehyde, triethylamine and acetonitrile, mixing and stirring for 30-40 minutes to obtain solution A, taking the flame-repellent intermediate and acetonitrile, stirring at 60-70degrees Celsius for 1.5-2 hours, reacting for 3-4 hours under the atmosphere of nitrogen, adding the amino graphene, continuously reacting for 6-8 hours, washing with ethanol, collecting product to obtain the oxidized graphene flame retardant, (b) taking polyester polyol, glycerol, triethanolamine, foaming agent dibutyltin dilaurate, oxidized graphene flame retardant titanium dioxide and deionized water, uniformly mixing to obtain the material B, mixing the material B with diphenylmethane diisocyanate, and stirring for 15-20 seconds to obtain the polyurethane foaming liquid, and (3) taking the honeycomb paper and the glass fiber felt, stacking and placing the glass fiber felt, honeycomb paper and glass fiberfelt in order to form framework, spraying polyurethane foaming liquid on two sides of the framework, and pressing and forming in the mold to obtain the finished product. An INDEPENDENT CLAIM is also included for flame-retardant and aging-resistant cover plate prepared by the preparation method.
