Description
Technical field
The present invention relates to a kind of organic polymer composites, are to be related to a kind of high-toughness high-strength POM more specifically
Material manufacture craft.
Background technique
The Research on Toughening of polyformaldehyde (POM) is one difficult point of POM study on the modification.There are many mechanisms and enterprise to poly- first at present
The toughening of aldehyde (POM) is studied, but be often constantly present certain aspect performance obvious shortcoming or cost performance it is not high and cannot
Large-scale production.More research direction is currently on the market: some co-mixing systems of molten alloy reinforced polyformaldehyde (POM)
Such as POM/PUR-T, POM/PP, POM/NBR, POM/PA and inorganic particle toughened POM system；
The toughening of POM is maximally efficient easy with elastic body toughening.Recent years elastic body toughening POM research thermoplastic poly
4 kinds of urethane elastomer (TPU), nitrile rubber (NBR), ethylene propylene diene rubber (EPDM), ethylene-octene copolymer (POE) elasticity
Body has the disadvantage that the toughening of POM wherein the toughening effect with TPU is best in existing polyformaldehyde toughening technology
Although by with elastomer can it is larger improve polyformaldehyde impact strength, the tensile strength and rigidity of polyformaldehyde
It declines by a big margin, it is difficult to obtain the strong and unyielding polyformaldehyde more balanced；Although polyformaldehyde can be improved in the polymer such as nano-rubber
Toughness, but increase rate is little, it is difficult to the polyoxymethylene blends of the high tenacity of system；Elastomer and nano-rubber are expensive,
High-ductility polyformaldehyde higher cost obtained；
With cladding, removing, intercalation isostructural elastomer and inorganic ultrafine powder ultrathin composite powder, with polyformaldehyde
It is blended, realizes that the performance advantage of elastomer and ultrafine inorganic powder is complementary, the dosage of expensive elastomer is greatly reduced, can make
It is standby that there is excellent rigidity and toughness, and the high-ductility polyformaldehyde blend that raw material cost is low, although the cost of raw material
It is low, but there is inconvenient scale mass production, while product quality is difficult to control stable disadvantage.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, provide it is a kind of production and it is easy to use, cost performance is high
High-toughness high-strength POM raw material.
Technical solution provided by the invention is as follows: high-toughness high-strength POM, is made of by weight following component, gathers
Formaldehyde: 60-80%, glass fibre: 10-30%, anti-impact modifier: 3-8%, antioxidant 1010: 0.1-1.0%, antioxidant
168:0.1-1.0%, formaldehyde absorbent: 0.2-1.0%, coupling agent: 0.1-0.5%, other auxiliary agents: 0.1-0.5%.
High-toughness high-strength POM raw material production procedure of the present invention is: first by polyformaldehyde, anti-impact modifier, anti-
Oxygen agent 1010, irgasfos 168, formaldehyde absorbent, coupling agent, other auxiliary agents proportionally weigh after in batch mixer mixed on low speed
10 minutes, melt flow rate (MFR) 9, batch mixer used mixed on low speed, and paddle should be with less than 0.5 centimetre of barrel gap supplementary material
Mixed effect answers visual various particles and powder substantially uniform, without obvious agglomerate or gathers；Double screw extruder is long using 36
Diameter ratio, moderate strength shearing；Extruding pelletization temperature is uniformly reduced by section step by step in 180-165 degree section, then is squeezed through twin-screw
Machine is added glass fibre by side in the screw combinations that moderate strength is sheared and carries out mixing extrusion out, using water cooling bracing
Pelletizing mode obtains high-toughness high-strength POM raw material.
The present invention effectively overcomes the defect of existing toughening POM, has the following advantages that.
The materials procurement of a kind of high-toughness high-strength POM of the invention and its manufacture craft, production is convenient, production
With product cost height easy to use, producing, thus changes reinforced polyformaldehyde and limited because of various reasons at present
The situation used, improves competitiveness comprehensively.
Specific embodiment
It is the most preferred embodiment of high-toughness high-strength POM raw material of the present invention below, does not therefore limit the present invention
Protection scope.
Embodiment one, provides a kind of high-toughness high-strength POM raw material, is made of by weight following component, polyformaldehyde:
70%, glass fibre: 19%, anti-impact modifier: 8%, antioxidant 1010: 1.0%, irgasfos 168: 0.7%, formaldehyde absorption
Agent: 0.6%, coupling agent: 0.4%, other auxiliary agents: 0.3%.
Polyformaldehyde uses standard flow grade, by polyformaldehyde, anti-impact modifier, antioxidant 1010, irgasfos 168, first
Aldehyde absorbent, coupling agent, other auxiliary agents proportionally weigh after in batch mixer mixed on low speed 10 minutes, melt flow rate (MFR) be
9, batch mixer uses mixed on low speed, and paddle should be with barrel gap less than 0.5 centimetre, and supplementary material mixed effect should visual various grains
Son and powder are substantially uniform, without obvious agglomerate or gather；Double screw extruder uses 36 draw ratios, moderate strength shearing；It squeezes
Prilling temperature is uniformly reduced by section step by step in 180-165 degree section out, then sheared through double screw extruder in moderate strength
Glass fibre progress mixing extrusion is added by side in the case of screw combinations, high-ductility is obtained using water cooling bracing pelletizing mode
Property high intensity POM raw material.
