Abstract

The invention discloses a halogen-free flame-retardant weather-proof PET / PPS alloy material which is prepared from the following raw materials in parts by weight: 80-120 parts of PET, 40-60 parts of PPS, 10-20 parts of a halogen-free flame retardant, 3-5 parts of a halogen-free flame retardant synergist, 3-5 parts of a toughening agent, 1-3 parts of an antioxidant and 1-3 parts of a lubricating dispersant. The preparation method comprises the following steps: (1) weighing raw materials; (2) putting all the raw materials into a mixer, and uniformly stirring to obtain a mixed material; and (3) putting the mixed material into a double-screw extruder, and carrying out extrusion granulation to obtain the product. The PET / PPS alloy material is excellent in mechanical property, flame retardant property and weather resistance, and has the advantages of being free of halogen, low in toxicity, good in stability, high in flame retardant efficiency, environmentally friendly and the like, the preparation method is simple and efficient, equipment is easy to operate, and the PET / PPS alloy material is suitable for large-batch industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more specifically relates to a halogen-free flame-retardant and weather-resistant PET / PPS alloy material and a preparation method thereof. Background technique [0002] Plastic alloys are a class of new materials with high performance, functionalization and specialization obtained by physical blending or chemical grafting. They can be widely used in automobiles, electronics, precision instruments, office equipment, packaging materials, building materials, etc. In the field of plastics, it can improve or enhance the performance of existing plastics and reduce costs, and has become one of the most active varieties in the plastics industry, growing very rapidly. [0003] Plastic alloys are mainly divided into general-purpose plastic alloys and engineering plastic alloys. Among them, general-purpose plastic alloys such as PVC (polyvinyl chloride), PE (polyethylene), PTT (polypropylene),...
