Abstract
The invention provides a preparation method of a halogen-free unsaturated polyester glass reinforced plastic molding material, belonging to the technical field of preparation of polymer materials. The preparation method is characterized by firstly throwing unsaturated polyester resins and a low shrinkage additive, which are weighed in parts by weight, into a beater to be quickly stirred, then adding an initiator, p-benzoquinone and a thickening agent, which are weighed in parts by weight, continuing stirring, then transferring the mixture to a kneader to be kneaded, then adding a filler, thermoplastic styrene butadiene rubber and a release agent, which are weighed in parts by weight, to the kneader, continuing kneading and finally adding reinforced fibers weighed in parts by weight and then kneading the materials, thus obtaining the halogen-free unsaturated polyester glass reinforced plastic molding material. The molding material has the advantages that the molding material is characterized in that the molding material has good strength, low shrinkage and excellent electrical property and is halide-free and can be applied to such parts as anticorrosion shells of autos and electrical appliances.
