Abstract
The invention provides preparation technology of a transparent environment-friendly flame-resistant PET special material. A double screw extruder is used under a certain technological condition, polyethylene terephthalate, PP-MAH (a compatibilizer), glass fiber (a reinforcing agent), and a fire retardant are used according to a certain ratio and technological processes to prepare the PET special material with enhanced flame-resistant performance. The material is low in water absorption and high in strength, and the flame resistance and heat resistance are all improved to certain levels. The material is suitable for a micro-motor current collector, a coil frame of a small DC motor, a large coil frame, a diverter, a component and a housing of a switch or a power distribution device, a lamp socket, a motor vacuum pump housing, a motor cam cover and gate, a windshield wiper motor housing and support, and a handle.
Description
Technical field
The present invention relates to polymer modification technology, especially environmental protection strengthens the preparation method of Flame-retardant PET PP Pipe Compound.
Background technology
PET is because having excellent performance, lower production cost and the higher ratio of performance to price, and be used widely in fields such as electric, mechanical, automobile component, in sedan-chair auto plastics, proportion also constantly increases.But its intensity is low, molding shrinkage is large, easy firing, limits its application as engineering materials.
For many years, in order to improve the above-mentioned shortcoming of PET, macromolecular material worker is devoted to strengthen it and flame-retardant modified always.Therefore, very necessary to the research strengthening Flame-retardant PET.
Summary of the invention
The invention provides a kind of enhancing Flame-retardant PET PP Pipe Compound, it is by polyethylene terephthalate, i.e. PET; Expanding material; Toughener; The compositions such as fire retardant.First by the fire retardant measured and PP-g-MAH(expanding material) add the mixing of high-speed mixer high speed, when temperature rises to 110 DEG C, stop mixing; Again the PET measured and glass fibre (toughener) are put into after high-speed mixer high speed mixes when temperature is down to 55 DEG C, through twin screw extruder extruding pelletization, prepare enhancing Flame-retardant PET.
Embodiment
This patent is described in further detail by following examples, and following example is illustrative, is not determinate, can not limit protection scope of the present invention with following example.
First by a certain amount of fire retardant and PP-g-MAH(expanding material) add the mixing of high-speed mixer high speed, when temperature rises to 110 DEG C, stop mixing; Again the PET measured and glass fibre (toughener) are put into after high-speed mixer high speed mixes when temperature is down to 55 DEG C, through twin screw extruder 285-300 DEG C extruding pelletization, prepare enhancing Flame-retardant PET.
The enhancing Flame-retardant PET PP Pipe Compound that the inventive method is made has excellent performance, and its performance index are as follows: (1) notched Izod impact strength/KJ/m
2>=10; (2) elongation at break/%>=10; (3) oxygen index/%>=30; (4) water-intake rate/%≤0.5; (5) tensile strength/MPa>=60.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (2)
1. strengthen a preparation method for Flame-retardant PET PP Pipe Compound, comprise material component, technical process, the dispersion state of component, and fabrication process condition.
2. a kind of preparation method strengthening Flame-retardant PET PP Pipe Compound according to claim 1, is characterized in that: twin screw extruder temperature when producing enhancing fire-retardant master granule controls between 285 DEG C to 300 DEG C.
