Abstract
The invention relates to an organic polymer composite material, in particular to halogen-free toughening buckling deformation prevention filling polyformaldehyde and a manufacturing process thereof; the halogen-free toughening buckling deformation prevention filling polyformaldehyde is composed of the following ingredients by weight ratio: 60.5-80 percent of polyformaldehyde,1-30 percent of halogen-free glass beads, 1-5 percent of flexibilizer, 0.1-1.7 percent of aldehyde adsorption agent, 0.1-0.4 percent of coupling agent, and 0.1-2.5 percent of other agents; the halogen-free toughening buckling deformation prevention filling polyformaldehyde and the manufacturing process thereof are halogen-free and environment-protection, and have the characteristics of good buckling deformation prevention performance and low shrinkage performance on the basis of keeping good comprehensive mechanical performances, and the shrinkage is uniform, the production procurement is convenient, thereby improving the competitiveness of the products and being suitable for producing face masks/shells which need to be tightly assembled and framework type manufacturing.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free toughening buckling deformation prevention filling polyformaldehyde and preparation method thereof.
Background technology
Polyoxymethylene be a kind of high comprehensive performance the big kind of engineering plastics, favorable mechanical performance, electrical property, wear resistance, dimensional stability and chemical proofing are arranged, particularly resistance to fatigue and self lubricity, wear resistance are the highest in all thermoplasticss, therefore, be widely used in replacing various non-ferrous metals and alloy to make automobile, machinery, instrument, agricultural machinery, chemical industry component, as gear, cam, bearing, lining, packing ring, valve, liquid conducting pipes, handle and pressure vessels for the chemical industry or the like.
But, because polyoxymethylene is again the crystal type material, when moulding, produces big internal stress easily, thereby cause the final product buckling deformation, like this, just having limited polyformaldehyde material, to be applied to size bigger than normal or to the dimension precision requirement high product.And that common in the market composite modified polyoxymethylene has shock strength is low, and anti-warpage effect is insufficient, the serial shortcoming that product appearance gloss is bad.And America 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.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 anti-buckling deformation that on comprehensive mechanical performance keeps good basis, increased good and shrinking percentage is low and shrink the halogen-free toughening buckling deformation prevention filling polyformaldehyde raw material of uniform feature.
Technical scheme provided by the invention is as follows: a kind of halogen-free toughening buckling deformation prevention filling polyformaldehyde of the present invention, form polyoxymethylene by weight by following composition: 60.5-80%, Halogen glass microballon: 1-30%: toughner: 1-5%; Inhale aldehyde agent: 0.1-1.7%; Coupling agent: 0.1-0.4%; Other auxiliary agents: 0.1-2.5%.
The preparation technology of halogen-free toughening buckling deformation prevention filling polyformaldehyde raw material of the present invention is: earlier with polyoxymethylene, Halogen glass microballon, toughner, the agent of suction aldehyde, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, the slow speed of revolution is mixing under the screw combinations situation that medium tenacity is sheared extrudes through twin screw extruder again, and the pelletizing of water-cooled tie rod makes the halogen-free toughening buckling deformation prevention filling polyformaldehyde 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 toughening buckling deformation prevention filling polyformaldehyde of the present invention and manufacture craft thereof, has halogen-free environmental, and it is good and shrinking percentage is low and shrink uniform feature to have increased anti-buckling deformation on comprehensive mechanical performance keeps good basis, production procurement is convenient, improved competitive power like this, 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 toughening buckling deformation prevention filling polyformaldehyde raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free toughening buckling deformation prevention filling polyformaldehyde is provided, and forms polyoxymethylene by weight by following composition: 69.7%, inhale the aldehyde agent: 0.7%; Halogen glass microballon: 25%: toughner: 2.2%; Coupling agent: 0.2%; Other auxiliary agents: 2.2%.
Earlier with polyoxymethylene, inhale aldehyde agent, 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 180 rev/mins rotating speed; Adopt water-cooled tie rod pelletizing mode, promptly make the halogen-free toughening buckling deformation prevention filling polyformaldehyde material through screening and dewatering.
