Embodiment

[0013] First, polyethylene terephthalate (PET) was dried at 130° C. for 6 hours, and poured into a weight loss scale. Next, dry the aliphatic polyketone at 100°C for 6 hours, pour the dried aliphatic polyketone and other additives into a high-speed mixer, stir at a low speed, mix well, pour it into a weight loss scale, and then pass it through a twin-screw extruder Mix and extrude. Shaped glass fibers are forced into Zone 7 via side feed. The blending temperature is 265-280°C, the screw speed is 350r / min, and the product is extruded, water-cooled, and pelletized. The produced material was dried at 130°C for 4 hours, and then standard mechanical property test specimens were prepared on an injection molding machine. The injection pressure is 60-90Mpa, the barrel temperature is 245-260°C, the mold temperature is 80°C, and the injection cycle is 40s. The raw material proportioning (mass percentage) of specific embodiment 1-5 is shown in Table 1:

Abstract

The invention relates to the field of organic macromolecules, in particular to a low-warpage polyester polyketone composite and a preparation method thereof. The composite is characterized by being prepared from raw materials as follows: polyethylene terephthalate, aliphatic polyketone, a profile glass fiber, a compatibilizer, polybrominated styrenics, sodium antimonate, an anti-dripping agent, a carboxylate nucleating agent, a nucleating agent compound and an antioxidant; a low-warpage reinforced flame-retardant alloy material can be prepared with the method comprising steps as follows: drying, mixing, extrusion and pelletizing; the raw materials comprise components in percentage by weight as follows: 40%-45% of polyethylene terephthalate, 5%-10% of aliphatic polyketone, 22%-30% of the profile glass fiber, 5%-8% of the compatibilizer, 6%-10% of polybrominated styrenics, 3%-5% of sodium antimonate, 0.2%-1% of the anti-dripping agent, 0.2%-0.8% of the carboxylate nucleating agent, 0.2%-0.8% of the nucleating agent compound and 0.3%-0.5% of the antioxidant.

Description

technical field [0001] The invention relates to the field of organic polymer materials, in particular to a low warpage polyester polyketone composite material and a production method thereof. Background technique [0002] We know that in the field of consumer electronics such as mobile phones and IPADs, the internal structural skeleton materials of products have realized the transformation of plastics instead of metals, and their processing and molding, mold design and manufacturing have relatively greater advantages than metal materials, and Saving costs, shortening processing time, and improving the progress of the industry. However, in terms of the selection of structural skeleton materials, foreign new material companies occupy most of the market share. However, the research and development of domestic alternative materials is at a backward stage, and there is still a gap with foreign materials in terms of key performance. In addition to meeting the UL94 vertical burni...
