Abstract

The invention belongs to the technical field of polymer materials, and in particular, relates to a long glass fiber reinforced polyketone material prepared from the following components in parts by weight: 45-85 parts of polyketone resin, 15-50 parts of continuous glass fibers, 0-0.5 part of a main antioxidant, 0-0.3 part of an auxiliary antioxidant, 0-1 part of a lubricant, and 0-5 parts of a stabilizer. With adopting of the long glass fiber reinforced polyketone material, the grain-sized dicing length of grains is 10-15 mm, fibers in the grains are in ordered arrangement in the resin along the grain-sized dicing direction, and the fiber length is equal to the grain length; the material also has excellent rigidity, impact toughness and good heat-resistant temperature, especially has excellent low-temperature impact properties, and has the advantages of simple design, low cost and high productivity.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a long glass fiber reinforced polyketone material and a preparation method thereof. Background technique [0002] Long glass fiber reinforced thermoplastics are a class of materials that have developed rapidly in recent years. Their most prominent advantages are high rigidity and strength, excellent heat resistance, creep resistance, dimensional stability, and long service life. There are significant differences between long glass fiber reinforced plastic particles and short glass fiber reinforced plastic particles. In short glass fiber reinforced plastics, due to the damage caused by the shearing action of the screw, the length of glass fiber is generally kept to about 0.2-1mm, while in long glass fiber reinforced plastics, the length of glass fiber can be kept to 3-6mm, which is short glass fiber. 10 times that of fiber reinforced plastics. [0003] At p...
