Abstract
The present invention relates to an organic polymer composite, particularly to a halogen-free and lustrous filled nylon 66 of warp resistance and a preparing technique thereof. The nylon 66 consists of the following constituents in a ratio by weight: 46.5 to 80% of nylon 66, 0 to 25% of talc powder, 0 to 25% of crystal whisker, 0 to 30% of halogen-free glass microsphere, 1 to 5% of toughening agent, 0.1 to 0.4% of coupling agent and 0.1 to 5.5% of other auxiliaries. The halogen-free and lustrous filled nylon 66 of warp resistance and the preparing technique thereof have the advantages that the nylon 66 is free of halogen and beneficial to environmental protection, the characteristics of good warp resistance, beautiful appearance, little and uniform shrinkage and capability of enduring high temperature are increased on the basis of excellent comprehensive mechanical properties, and production and procurement are convenient, so the comprehensive competitive power is improved. The present invention is suitable for producing cover/casing class components having tight assembly and good appearance requirements.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free and lustrous filled nylon 66 of warp resistance and preparation method thereof.
Background technology
Nylon 66 is to use one of maximum several engineering plastics at present, and this class material is widely used in every field, is seen everywhere in industry and our daily life.And Europe/Japan or the like developed country has started all restrictions of foreign imported product for various reasons at present, has set up a series of barrier, wherein, to the material Halogen requirement of electric equipment products, is exactly one of them.Therefore cause bigger puzzlement to the more export enterprise of China.Simultaneously, because nylon 66 is again the crystal type material, when moulding, produces big internal stress easily, thereby cause the final product buckling deformation.The existing nylon 66 material of producing anti-warpage is to adopt talcum powder to play anti-warping effect in the existing market, and it is low to have intensity, and anti-warpage effect is insufficient, influences product appearance gloss, the serial shortcoming that material flowability is bad.The present technique invention produces in order effectively to overcome this phenomenon.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of on comprehensive mechanical performance keeps good basis, increased the good and appearance looks elegant of anti-buckling deformation and shrink little and even, and the halogen-free and lustrous filled nylon 66 of warp resistance raw material of feature that can withstand higher temperatures.
Technical scheme provided by the invention is as follows: a kind of halogen-free and lustrous filled nylon 66 of warp resistance of the present invention, form nylon 66:46.5-80%, talcum powder: 0-25% by weight by following composition; Whisker: 0-25%; Halogen glass microballon: 0-30%: toughner: 1-5%; Coupling agent: 0.1-0.4%; Other auxiliary agents: 0.1-5.5%.
The preparation technology of halogen-free and lustrous filled nylon 66 of warp resistance of the present invention is: earlier with nylon 66, Halogen glass microballon, toughner, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, add talcum powder in proportion by the side and the whisker slow speed of revolution is mixing extrudes under the screw combinations situation that medium tenacity is sheared through twin screw extruder again, the pelletizing of water-cooled tie rod makes the halogen-free and lustrous filled nylon 66 of warp resistance material through screening and dewatering.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of halogen-free and lustrous filled nylon 66 of warp resistance of the present invention and manufacture craft thereof, halogen-free environmental, on comprehensive mechanical performance keeps good basis, increased the good and appearance looks elegant of anti-buckling deformation and shunk little and even, feature that can withstand higher temperatures, production procurement is convenient, improve competitive power like this, preferablyly be used to produce the face shield/shell class product that needs close fit to possess good appearance simultaneously.
Embodiment
Below be the most preferred embodiment of halogen-free and lustrous filled nylon 66 of warp resistance raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free and lustrous filled nylon 66 of warp resistance is provided, and forms nylon 66:53%, the high pigment black masterbatch of nylon 66 carriers: 1.5% by weight by following composition; Talcum powder: 15%; Whisker: 8%; Halogen glass microballon: 18%; Toughner: 2%; Coupling agent: 0.3%; Other auxiliary agents: 2.2%;
Earlier with nylon 66, the high pigment black masterbatch of nylon 66 carriers, Halogen glass microballon, toughner, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, the combination of medium tenacity shear screw, and setting is not higher than 230 rev/mins rotating speed; Talcum powder and whisker are added in proportion by the side; Adopt water-cooled tie rod pelletizing mode, promptly make the halogen-free and lustrous filled nylon 66 of warp resistance material through screening and dewatering.
Claims (2)
1. a halogen-free and lustrous filled nylon 66 of warp resistance is characterized in that: form nylon 66:46.5-80%, talcum powder: 0-25% by weight by following composition; Whisker: 0-25%; Halogen glass microballon: 0-30%: toughner: 1-5%; Coupling agent: 0.1-0.4%; Other auxiliary agents: 0.1-5.5%.
2. method for preparing halogen-free and lustrous filled nylon 66 of warp resistance, it is characterized in that: comprise the steps: earlier with nylon 66, Halogen glass microballon, toughner, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, add talcum powder in proportion by the side and the whisker slow speed of revolution is mixing extrudes under the screw combinations situation that medium tenacity is sheared through twin screw extruder again, the pelletizing of water-cooled tie rod makes the halogen-free and lustrous filled nylon 66 of warp resistance material through screening and dewatering.
