Example Embodiment

[0015] Example 1

[0016] Pour the dried 2 parts of titanium dioxide and 13 parts of aluminum silicate powder into a high-mixer with a set temperature of 100-120℃ and a stirring speed of 3000 rpm, and then add 1 part of lanthanum phytate and 1 part of lanthanum stearate And 0.1 part of silane coupling agent, the speed is adjusted to 5000 rpm and stirred for 30 minutes. The above mixture and 10 parts of EPDM rubber are used to prepare elastomer-coated composite materials. Then, the elastomer-coated composite material and 100 parts of polyethylene terephthalate are melt blended on a twin-screw extruder to prepare a polyethylene terephthalate composite material. The temperature of each section of the extruder is 180-240°C, and the screw speed is 100-300rpm. After granulation and drying, prepare national standard mechanical properties test strips on the injection molding machine. The temperature of each section of the injection molding machine is 250-260°C, the injection speed is 1...

Abstract

The invention discloses a composite material of polyethylene terephthalate and a preparation method thereof. Mix and stir titanium dioxide, calcium carbonate or aluminum silicate, lanthanum phytate or lanthanum cerium phytate complex salt, lanthanum stearate or lanthanum cerium stearate complex salt and silane coupling agent at 90-110°C; EPDM rubber or maleic anhydride grafted EPDM rubber is mixed and stirred to obtain a blend; finally, the blend is melt-blended with polyethylene terephthalate at 180-240°C, Promptly obtain the product of the present invention. The preparation method of the present invention is simple to operate, and the polyethylene terephthalate composite material prepared by the method not only has good toughness and strength, but also has excellent properties in oxidation resistance, thermal stability, light stability, light shielding and metal Outstanding performance in ion passivation. In addition, the product of the invention also has the advantages of environmental protection and low cost, enabling PET materials to be more widely used in the field of engineering plastics.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a composite material of polyethylene terephthalate and a preparation method thereof. Background technique [0002] Polyethylene terephthalate, referred to as PET, is a common resin in daily life. It is a milky white or light yellow, highly crystalline polymer. In order to extend the service life of polyethylene terephthalate and improve its performance, it is often necessary to add certain additives in the production process to achieve wear resistance, heat resistance, chemical corrosion resistance, impact resistance, good electrical insulation, etc. performance. [0003] Chinese patent 200310103224.7 discloses a polyethylene terephthalate composition, which contains the following components: polyethylene terephthalate, polyethylene terephthalate with a cross-linked structure with an average particle size of 30-200nm Phenylpyril powder rubber, etc.; wherei...
