Abstract
The invention relates to an organic polymer composite, in particular to halogen-free anti-buckling deformation reinforced nylon 66 and a preparation method thereof. The nylon 66 consists of the following components by weight ratio: 46.5-80% of nylon 66; 1-35% of halogen- and alkali-free glass fiber ; 1-30% of halogen-free glass beads; 1-5% of flexibilizer; 0.1-0.4% of coupling agent; and 0.1-5.5% of other agents. The halogen-free anti-buckling deformation reinforced nylon 66 and the production process thereof have no halogen, are environment-friendly, are added with the characteristic of good anti-buckling deformation on the basis of keeping good synthetic mechanical properties, and have convenient production and purchasing, thus improving the competitive force roundly and being more applicable to producing masks/shells needing to be tightly assembled and product skeleton workpieces.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free anti-buckling deformation reinforced nylon dragon 66 and preparation method thereof.
Background technology
Glass fiber reinforced 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 the more export enterprise of China is seriously perplexed.Simultaneously, cause the orientation anisotropy easily owing to glass fibre has than big L/D ratio, and nylon 66 is crystal type materials, produces big internal stress easily when moulding, thereby causes the final product buckling deformation.Existing Reinforced Nylon 66 materials of producing anti-warpage are 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, a kind of halogen-free anti-buckling deformation reinforced nylon dragon 66 raw materials that increased the good feature of anti-buckling deformation on comprehensive mechanical performance keeps good basis are provided.
Technical scheme provided by the invention is as follows: a kind of halogen-free anti-buckling deformation reinforced nylon dragon 66 of the present invention, form nylon 66:46.5-80%, Halogen alkali-free glass fiber: 1-35% by weight by following composition; Halogen glass microballon: 1-30%: toughner: 1-5%; Coupling agent: 0.1-0.4%; Other auxiliary agents: 0.1-5.5%.
The preparation technology of halogen-free anti-buckling deformation reinforced nylon dragon 66 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, in proportion add the Halogen alkali-free glass fiber slow speed of revolution mixing extrude by the side through twin screw extruder under the screw combinations situation that medium tenacity is sheared again, the pelletizing of water-cooled tie rod makes halogen-free anti-buckling deformation through screening and dewatering and strengthens the environmental protection nylon 66 material.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of halogen-free anti-buckling deformation reinforced nylon dragon 66 of the present invention and manufacture craft thereof, halogen-free environmental, keep having increased the good feature of anti-buckling deformation on the good basis at comprehensive mechanical performance, production procurement is convenient, comprehensive like this competitive power that improved, face shield/shell and the product skeleton class product that is used to produce the need close fit preferably.
Embodiment
Below be the most preferred embodiment of halogen-free anti-buckling deformation reinforced nylon dragon 66 raw materials of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free anti-buckling deformation reinforced nylon dragon 66 is provided, and forms nylon 66:59%, the high pigment black masterbatch of nylon 66 carriers: 1.5% by weight by following composition; Halogen alkali-free glass fiber: 17%; 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; The Halogen alkali-free glass fiber is added in proportion by the side; Adopt water-cooled tie rod pelletizing mode, promptly make halogen-free anti-buckling deformation reinforced nylon dragon 66 materials through screening and dewatering.
Claims (2)
