Abstract

The invention discloses a bamboo fiber reinforced nylon composite material and a preparation method thereof. The bamboo fiber reinforced nylon composite material is prepared from the raw materials inpercentage by weight: 33-72% of PA6, 0-35% of PA1212, 10-40% of bamboo fiber, 1-6% of lysine based isocyanate, 2-10% of toughening agents and 1-8% of POE-g-MAH. The preparation method comprises the steps that the PA6, the PA1212, the bamboo fiber, the lysine based isocyanate, the toughening agents and the POE-g-MAH are mixed uniformly by using a mixing machine, and then the bamboo fiber reinforcednylon composite material is obtained after melt blending extrusion, bracing, air cooling and pelleting are carried out by using a twin-screw extruder. According to the bamboo fiber reinforced nylon composite material and the preparation method thereof, the material mechanical properties are excellent, the preparation cost is low, and the preparation technology is simple.

Description

technical field [0001] The invention relates to the technical field of nylon composite materials, in particular to a bamboo fiber reinforced nylon composite material and a preparation method thereof. Background technique [0002] Bamboo fiber is a kind of natural environment-friendly green fiber in the true sense. Due to its low cost, low density and good processability, bamboo fiber has become the fifth largest natural fiber after cotton, hemp, wool and silk. It is a high-strength low-elongation fiber with high abrasion resistance and good dyeability. In addition, bamboo fiber has natural characteristics incomparable to other fibers such as rich sources, green environmental protection, negative ion health care, natural antibacterial, antibacterial, mite removal, deodorization, moisture absorption and release, good air permeability, and UV resistance. A big hot spot for friendly material. In addition, the extensive use of bamboo fiber is conducive to alleviating the shorta...
