Abstract
The invention relates to glass fiber / thermoplastic plastic granules and a method for preparing the same. The glass fiber / thermoplastic plastic granules comprise glass fibers, thermoplastic plastics and additives and particularly comprise, by weight, 100 parts of the glass fibers, 15-20 parts of the thermoplastic plastics, 20-25 parts of cyclohexanone, 20-25 parts of tetrahydrofuran, 1-5 parts of trithione antimony isooctyl acetate stabilizers, 5-10 parts of epoxy glyceride plasticizers, 1-5 parts of N-hydroxymethyl acrylamide cross-linking agents, 0.1-0.5 part of macrogol ester lubricants and 3-8 parts of tricresyl phosphate flame retardants. The method includes particular steps of melting glass balls; drawing wires; feeding the wires into cotton collecting chambers; uniformly mixing the wires and slurry with one another at outlets to obtain mixtures; feeding the mixtures into curing furnaces along with movement of cotton collecting nets and curing the mixtures at the low temperatures; smashing the mixtures in smashing machines; plasticizing and cutting the mixtures in double-screw extrusion granulators to obtain the glass fiber / thermoplastic plastic granules. The glass fiber / thermoplastic plastic granules and the method have the advantages that the glass fiber / thermoplastic plastic granules prepared by the aid of the method are high in strength, toughness and plasticity, low in cost and easy to process, and technologies for the glass fiber / thermoplastic plastic granules are simple.
Description
technical field [0001] The invention relates to a thermoplastic particle and a preparation method thereof, in particular to a glass fiber / thermoplastic particle and a preparation method thereof, belonging to the field of composite materials. Background technique [0002] Plastic particles, a synthetic polymer compound, also commonly known as plastic or resin, can change shape freely. It is a material made of monomer raw materials by synthesis or condensation reaction polymerization, and is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. [0003] Plastics are generally divided into two types: thermoplastic and thermosetting. The thermoplastic type means that the material will soften after heating, and will harden after cooling to the shape we need, which can be softened and shaped repeatedly. The thermosetting type will condense into a certain shape after heating, and the internal structure of the molecule will...
