Problems solved by technology

This kind of fiber is prepared from volcanic lava by melting wire drawing method. It has mechanical properties similar to glass fiber, and different from glass fiber. This material can be in long-term contact with the human body. Therefore, composite materials prepared from this fiber It can overcome the shortcomings of glass fiber composite materials, and the cost is low, but due to the limited resources of volcanic lava, the development and application prospects are limited to a certain extent
As a new type of high-performance fiber, the research on its composite material has just begun. At present, there is no public report on the preparation of high-performance fiber composite material using basalt fiber as a reinforcing phase.

Embodiment 1

[0028] PET and basalt fibers with a diameter of 3 μm were dried in an oven at 110°C for 4 hours, then 5.00kg of PET, 200g of polyethylene glycol, 400g of TAIC, and 50g of additives were mixed evenly with a mixer, and then added to a 6-zone heating Injection machine, melted and mixed in twin-screw extruder with length-to-length ratio of 32:1, 3.35kg of basalt fiber was added to the vent hole in zone 5, and the heating temperatures in zone 6 were 225±5°C and 265±5°C respectively. 5°C, 270±5°C, 275±5°C, 275±5°C, 275±5°C, the temperature of the machine head is 270±5°C, and the mixed material is cut into pellets. Dry it in an oven at 80°C for 4 hours, and then put it into a nitrogen-protected polyethylene bag and irradiate 70kGy to prepare a composite material.

Embodiment 2-5

[0030] Raw material weight percent composition and processing technology are the same as embodiment 1, but vinyl polyfunctional group monomer becomes trimethylolpropane triacrylate (TMPTA), pentaerythritol triacrylate (PETA) successively in embodiment 2-5 , Phthalate glycol diacrylate (PDDA), tripropylene glycol diacrylate (TPGDA).

Embodiment 6

[0032] PET and basalt fibers with a diameter of 7 μm were dried in an oven at 110° C. for 4 hours, and the processing technology was the same as in Example 1. The composition of raw materials is as follows: PET 5.00kg, basalt fiber 2.5kg, polypropylene glycol 300g, TMPTA 730g, processing aid 170g.

Abstract

The invention discloses a polyethylene terephthalate (PET) / basalt fiber composite material and a preparation method thereof, the components of which comprise macromolecule polyester resin, basalt fiber, vinyl multi-functional monomer and composition processing aid. At the temperature of 220 DEG C to 280 DEG C, other components excluding basalt fiber are firstly melt and blended together by using a twin-screw and then continuous basalt fiber is added by a special material port after the melting of the materials. Finally PET / basalt fiber composite material is prepared by the irradiation to the blended material particles. The PET / basalt fiber composite material has good processing property and excellent mechanical property.

Description

technical field [0001] The present invention relates to the preparation of a kind of fiber composite material, more specifically, it is a kind of polyethylene terephthalate / basalt fiber composite material and its preparation method Background technique [0002] Polyethylene terephthalate (PET) is a condensation polymer of terephthalic acid and ethylene glycol, and its average molecular weight is about 20.000-30.000. It is a highly crystalline polymer with a melting point of 260°C. It has excellent mechanical properties, wear resistance and impact resistance, and has the advantages of high rigidity, low water absorption and good dimensional stability. [0003] At present, the annual output of PET in my country has ranked first in the world, and its industrial application is mainly concentrated in the fields of fibers, water bottles and packaging sheet materials, while the research and development and application in the field of engineering plastics are still in its infancy. ...
