Abstract
The invention relates to an organic polymer composite, in particular to halogen-free reinforced nylon and preparation method thereof, wherein the halogen-free reinforced nylon consists of the following components in percent by weight: 35-65 wt% of high-temperature nylon, 5-15 wt% of main flame retardants, 2-6 wt% of auxiliary flame retardants, 10-20 wt% of halogen-free and alkali-free glass fibers, 1-5 wt% of high-flow promoters, 0.1-3.0 wt% of heat stabilizers, 0.3-2.0 wt% of lubricants and 0.3-5.5 wt% of other assistants. The halogen-free reinforced nylon and the preparation method thereof of the invention can integrate high flame retardance, high strength and high melting point into a whole so that the material can resist the continuous high temperature of 200 DEG C, keep favorable size stability, and has favorable ductility and low warpage, and the halogen-free reinforced nylon can be used in almost all application fields with different sizes and strict requirements.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free reinforced nylon raw material.The invention still further relates to the method for making this nylon raw material.
Background technology
At present, the RoHS rules impel industry when the enterprising trip link actuator surface mounting of printed circuit board (PCB), employing meets the weldprocedure of unleaded regulation, thus higher heatproof and environmental requirement are proposed material, simultaneously, the differentiation design of various industry and civilian product has also proposed to tolerate the still requirement of high safety of harsh and unforgiving environments more to material, and will meet various environmental protection instruction regulations simultaneously.Simultaneously, the thin-walled property of product and complex construction propose high requirement to the flowability of material again.
This extraordinary matrix material invention is arisen at the historic moment under this background just, with high flame retardant, high strength and high-melting-point can roll into one, this material can anti-200 ℃ continuous high temperature, and can also keep good dimensional stability, and having good ductility and low warpage, nearly all size difference, strict Application Areas can both be used.This product fully meets European Union's " waste and old electric electric installation " (WEEE) and " objectionable impurities limits the use of instruction " (RoHS) rules and PAHS or the like environmental requirement.Compare the use traditional material, this product has high-end machinery and electric property more, also have characteristics such as easy processing, good looking appearance and laser marking simultaneously, and the electrical characteristic of the chemical resistant properties excellent in dimensional stability of identical intensity and toughness brilliance are provided under wet environment.Compare with traditional nylon 6,66, its water regain is few 70%, and the interior coefficient of expansion is low, with metal species seemingly.
Summary of the invention
The objective of the invention is to effectively overcome the defective of existing nylon, a kind of have high flame retardant, high strength and dystectic halogen-free reinforced nylon raw material are provided.
Technical scheme provided by the invention is as follows: a kind of halogen-free reinforced nylon raw material, form by weight by following composition: high-temperature nylon: 35-65%, main flame retardant: 5-15%, auxiliary flame retardant: 2-6%; Halogen alkali-free glass fiber: 10-20%; High flow promotor: 1-5%; Thermo-stabilizer: 0.1-3.0%, lubricant: 0.3-2.0%, other auxiliary agents: 0.3-5.5%.
The preparation method of halogen-free reinforced nylon of the present invention, comprise the steps: earlier the high-temperature nylon particle to be toasted 4-5 hour with the temperature of 100 degree, being mixed in proportion the back with main flame retardant then placed 12 hours under 50 degree constant temperatures, again in time and auxiliary flame retardant, high flow promotor, thermo-stabilizer, lubricant, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, in time add Halogen alkali-free glass fiber by the side through twin screw extruder under the screw combinations situation that medium tenacity is sheared again and carry out mixing extruding, the pelletizing of water-cooled tie rod makes a kind of halogen-free reinforced nylon material through screening and dewatering again.
The present invention has effectively overcome the defective of existing nylon, has the following advantages:
A kind of halogen-free reinforced nylon of the present invention can roll into one high flame retardant, high strength and high-melting-point, this material can anti-200 ℃ continuous high temperature, and can also keep good dimensional stability, and have good ductility and a low warpage, nearly all size difference, strict Application Areas can both be used, and have high-end machinery and electric property, also have characteristics such as easy processing, good looking appearance and laser marking simultaneously, and the electrical characteristic of the chemical resistant properties excellent in dimensional stability of identical intensity and toughness brilliance are provided under wet environment.Compare with traditional nylon 6,66, its water regain is few 70%, and the interior coefficient of expansion is low, with metal species seemingly.
Embodiment
Below be the embodiment of halogen-free reinforced nylon of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free reinforced nylon is provided, and is made up of by weight following composition: high-temperature nylon: 60%, and main flame retardant: 10%, auxiliary flame retardant: 5%; Halogen alkali-free glass fiber: 15%; High flow promotor: 4%; Thermo-stabilizer: 2%, lubricant: 2%, other auxiliary agents: 2%.
The preparation method of halogen-free reinforced nylon of the present invention, comprise the steps: earlier the high-temperature nylon particle to be toasted 4-5 hour with the temperature of 100 degree, being mixed in proportion the back with main flame retardant then placed 12 hours under 50 degree constant temperatures, again in time and auxiliary flame retardant, high flow promotor, thermo-stabilizer, lubricant, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, in time add Halogen alkali-free glass fiber by the side through twin screw extruder under the screw combinations situation that medium tenacity is sheared again and carry out mixing extruding, the pelletizing of water-cooled tie rod makes a kind of halogen-free reinforced nylon material through screening and dewatering again.
