Description
Technical field
The invention belongs to field of polymer composite material, be specifically related to a kind of nylon 6 Blends containing expanding material and preparation method thereof.
Background technology
Nylon 6, i.e. polymeric amide-6, be PA6 again, has excellent process based prediction model, has that mechanical strength is high, good toughness, wear-resisting, resistance to wet goods feature, thus receives increasing concern in fields such as electronic apparatus, mechanical means, life households.But the shortcomings such as its strong alkali-acid resistance is poor, low temperature impact strength is low, easy water suction and creep resistance are not enough, make it be very limited in the application.Generally, in resin, add appropriate fortifying fibre, as glass fibre, effectively can transmit stress, the mechanical property of plastics is significantly improved.But simple interpolation fortifying fibre, the surface fiber of the goods obtained exposes, and even occurs product deformation.
For above situation about occurring, people have also been made large quantifier elimination.Consider, when nylon 6 and other materials blended, add some expanding material and the consistency of co-mixing system can be made more stable, but some expanding material be harmful.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of nylon 6 Blends containing expanding material, and makes stable system, consumption few, improves the mechanical properties such as the elongation at break of blend, shock strength.
In order to solve above-mentioned technical problem, the invention provides a kind of nylon 6 Blends containing expanding material, it comprises nylon 6, gypsum fiber and expanding material, and described expanding material is end polyamino dendritic macromole PESAM, and its structural formula is such as formula shown in (I):
In of the present invention one concrete technical scheme, it is 0.1-5% ︰ 69-94% ︰ 5-30% that PESAM ︰ nylon 6 ︰ gypsum fiber accounts for nylon 6 Blends weight percent respectively; Preferably, in blend total amount, the weight percent of PESAM ︰ nylon 6 ︰ gypsum fiber is 0.1-3% ︰ 69-87% ︰ 10-30%; More preferably, in blend total amount, the weight percent of PESAM ︰ nylon 6 ︰ gypsum fiber is 0.1-2% ︰ 75-85% ︰ 15-23%; The weight percent being preferably PESAM ︰ nylon 6 ︰ gypsum fiber is again 1.5% ︰ 78.5% ︰ 20%.
The technical problem of a second aspect of the present invention, provide the preparation method also including gypsum fiber nylon 6 Blends, it comprises the steps:
First nylon 6 is placed in vacuum drying oven in 50 DEG C of dryings 2 hours, by formula, PESAM glue head dropper is added drop-wise in nylon 6, stirs; Then the material mixed is added twin screw extruder; gypsum fiber is added from first venting port of twin screw extruder simultaneously and melt extrude; various desired product is obtained through wire drawing, cooling, pelletizing; the machine barrel processing temperature of described twin screw extruder is set as 230 ~ 260 DEG C, and main-machine screw rotating speed is 600r.min
-1.
In of the present invention one concrete technical scheme, described twin screw extruder Gong She seven district, the firstth district is 230 DEG C, and the secondth district is 240 DEG C, 3rd district is 245 DEG C, and the 4th district is 255 DEG C, and the 5th district is 260 DEG C, 6th district is 255 DEG C, and SECTOR-SEVEN is 250 DEG C, and head temperature is 245 DEG C.
Expanding material in the present invention is end polyamino dendritic macromole PESAM, and its structural formula is such as formula shown in (I), and end group is 16 amino:
The preparation method of end polyamino dendritic macromole PESAM, the method comprises the following steps:
By Viscoat 295 and quadrol, carry out Michael reaction 3-6 hour in room temperature, carry out separating-purifying with methyl alcohol as precipitation agent; Add three (2-amino-ethyl) amine again in room temperature reaction 6-10 hour, underpressure distillation, obtain end polyamino dendritic macromole, wherein, the mass ratio of trimethylolpropane tris Bing olefin(e) acid Zhi ︰ Yi bis-An ︰ tri-(2-amino-ethyl) amine is 20-30 ︰ 1 ︰ 40-50.
The nylon 6 Blends that the present invention will hold polyamino dendritic macromole PESAM and gypsum fiber to be added into preparation in nylon 6 on a small quantity, without the need to adding other additives, toughen and intensify is effective, and the mechanical properties such as tensile strength, elongation at break, shock strength all obtain significance and improve.
