Abstract
The invention relates to an organic polymer composite material, in particular to a manufacture process of halogen-free nylon. The halogen-free nylon is composed of the following components, by weight, of 45.5-75% of high temperature nylon, 5-25% of halogen-free alkali-free glass fiber, 0.1-3.0% of glass fiber treating agent, 0.3-2.0% of lubricating agent and 0.1-0.5% of other auxiliaries. The halogen-free nylon and the manufacture process can be used for various injection molding and extrusion molding fields and can meet various machining requirements of polyamide and glass fiber polyamide, excellent mechanical strength, excellent chemical resistance, excellent size stability, excellent electrical characteristics and good appearance are achieved, the same strength toughness can be provided in a moist environment, and the halogen-free nylon is convenient to produce and purchase and low in cost.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly relate to a kind of halogen-free nylon manufacture craft.The invention still further relates to the method for making this nylon raw material
Background technology
At present, the application that substitutes metal in the industry with plastics in the world constantly enlarges, and the development of nylon makes this speed and scope more extensive.Halogen-free nylon Halogen low toxicity is a kind of environment-friendly type nylon, meets European environment protection requirement.This material can be used for various injection mouldings and extrusion molding occasion, can satisfy polymeric amide, the various processing requests of glass polymeric amide, has excellent physical strength, and under wet environment, provide identical intensity and toughness, remarkable chemical resistant properties, dimensional stability, excellent electrical characteristic, good outward appearance.
Many motors of new design invention and casing component equally also useful nylon replace the trend of metal and thermosetting material.These all will strengthen the demand to this nylon material, thereby drive the nylon market requirement.But the observable parts that are exposed to the outside Duo again a very inaccessible requirement than hidden parts inside, that be exactly the appearance looks elegant requirement in bearing high strength, do not have in appearance flaw.
Basically existing halogen-free nylon is all being monopolized market by external manufacturer, and the halogen-free nylon that meets environmental requirement holds at high price, and has complex manufacturing, the inferior positions such as purchasing of raw materials inconvenience.
Series product of the present invention fully meet European Union's " waste and old electric electric installation " (WEEE) and " objectionable impurities limits the use of instruction " (RoHS) rules and other environmental regulations, and strict Application Areas can both be used.
Summary of the invention
The object of the invention is to effectively overcome the defective of existing nylon, provide a kind of production procurement convenient, cheap halogen-free nylon raw material.
Technical scheme provided by the invention is as follows: high-temperature nylon: 45.5-75% ， is Wu Tooth alkali-free glass fiber: 5-25%, glass treatment agent: 0.1-3.0%, lubricant: 0.3-2.0%, other auxiliary agents: 0.1-0.5%.
The preparation method of halogen-free nylon of the present invention, comprise the steps: first the high-temperature nylon particle to be toasted 3-4 hour with the temperature of 100 degree, then under 50 degree constant temperatures, placed 12 hours after being mixed in proportion with the glass treatment agent, again in time and the glass treatment agent, 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 in the screw combinations situation that medium tenacity is sheared again and carry out mixing extrusion, the water cooling bracing pelletizing makes a kind of halogen-free 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 nylon of the present invention can be used for various injection mouldings and extrusion molding occasion, can satisfy polymeric amide, the various processing requests of glass polymeric amide, has excellent physical strength, and under wet environment, provide identical intensity and toughness, remarkable chemical resistant properties, dimensional stability, excellent electrical characteristic, good outward appearance also meets all environmental requirements simultaneously, and performance and import same type of material are similar, price but only is equivalent to the same type of material 1/3rd of import between half, and production procurement is convenient, has changed external producer and has monopolized the market, the situation that selling price is high, comprehensive like this competitive power that improved.
Embodiment
Below be the embodiment of halogen-free nylon of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free nylon is provided, and is made of by weight high-temperature nylon following composition: 45.5-75%, Halogen alkali-free glass fiber: 5-25%, glass treatment agent: 0.1-3.0%, lubricant: 0.3-2.0%, other auxiliary agents: 0.1-0.5%.
First the high-temperature nylon particle was toasted 3-4 hour with the temperature of 100 degree, then under 50 degree constant temperatures, placed 12 hours after being mixed in proportion with the glass treatment agent, again in time and glass treatment agent, 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 in the screw combinations situation that medium tenacity is sheared again and carry out mixing extrusion, the water cooling bracing pelletizing makes a kind of halogen-free nylon material through screening and dewatering again.
