Fluorescent rotational molding special material and preparation method thereof

The invention provides a fluorescent rotational molding special material and a preparation method thereof. The formula of the special material includes, by weight ratio, 60-85 parts of high-density polyethylene, 15-40 parts of linear low-density polyethylene, 1.5-2.5 parts of a processing auxiliary agent, 0.5-1 part of a compatilizer, and 1.5-3 parts of a fluorescent agent. The special material issimple in preparation method and easy to realize industrial operation, and complex equipment is not needed; the two kinds of polyethylene resin powder can be mixed, resin containing the fluorescent agent can be distributed on the outer surface of a product by utilizing the difference between the melting points and fluidity of the two, so that the addition amount of the fluorescent agent can be decreased, and production costs can be reduced; and the product molded by the special material is excellent in performance and can continuously emit fluorescence at night, and light absorbing, light storing and light emitting p
