Abstract
The invention relates to a black thermo-oxidative-aging-resistant long-glass-fiber-reinforced polypropylene (LFTPP) material. The material mainly comprises the following components in parts by weight: 57-63 parts of PP, 5-6 parts of graft PP, 30-35 parts of glass fiber, 0.2-0.5 part of main antioxidant, 0.2-0.5 part of auxiliary antioxidant, 0.3-0.4 part of stabilizer, 0.3-0.4 part of calcium stearate and 0.4-0.6 part of black color master. The material is prepared by the following steps: premixing the PP, graft PP, antioxidant, stabilizer and black color master, extruding to a mold by a double screw extruder, soaking the glass fibers with the mold, drawing, and granulating. The product can resist thermo-oxidative aging at 155 DEG C for 1000 hours without powdering or yellowing on the surface.
Description
Technical field
The present invention is the technical field that modifying plastics is processed, and particularly relates to a kind of long glass fiber-reinforced polypropylene LFTPP material of black heat oxygen aging resistance.
Background technology
Long glass fiber-reinforced polypropylene LFTPP (Long Glass Fiber Reinforced Thermoplastics) has the distinguishing features such as high strength, the high dimensional stabilizing of high rigidity, low warpage, long service life, resistance to creep, makes LFTPP material apply to widely automobile industry.But black ratio is easier to absorb heat, and PP easily degraded under the environment of high temperature for a long time, so the test of the heat oxygen aging resistance of the LFTPP material of black is the examination item important to LFTPP material property.
Summary of the invention
For problems of the prior art, product of the present invention can be spent by heat oxygen aging resistance 155, and 1000 hours, not efflorescence of surface, non-yellowing.Its technical scheme adopting is: a kind of long glass fiber-reinforced polypropylene LFTPP material of black heat oxygen aging resistance, it is characterized in that, and its component represents mainly to comprise by weight:
Wherein, described primary antioxidant is a kind of phenolic antioxidant, and auxiliary antioxidant is a kind of phosphite ester kind antioxidant, and stablizer is a kind of hindered amines stablizer.
Preparing formula optimization weight of the present invention (part) proportioning is:
Preparing formula optimization weight of the present invention (part) proportioning is:
The invention also discloses a kind of manufacture method of long glass fiber-reinforced polypropylene LFTPP material of black heat oxygen aging resistance, be equipped with each component in formula, adopt PP and grafting PP, oxidation inhibitor, stablizer, black masterbatch to pass through premix, through twin screw extruder, arrive mould, make again glass fibre by mould infiltrate, draw pelletizing adopt PP and grafting PP, oxidation inhibitor, stablize and, black masterbatch passes through premix, through twin screw extruder, arrive mould, then make glass fibre infiltrate, draw pelletizing by mould.
Beneficial effect: product of the present invention can be spent by heat oxygen aging resistance 155,1000 hours, not efflorescence of surface, non-yellowing.
