Description
Technical field
The present invention relates to a kind of technical field of modification of PP composite material more particularly to a kind of high strength glass fibers
Reinforced polypropylene material and preparation method thereof.
Background technology
Polypropylene material has in daily life and industrial and agricultural production and widely answers as one of five big general-purpose plastics
With, such as applied to appliance shell, washing machine drum, electric tool.But with industrialization development, how to reduce cost becomes very
More companies exploitation new products are done one's utmost the target pursued, therefore, before some commonly Engineering Plastics Parts at leisure by glass
Fiber reinforced polypropylene composite product is replaced.
Glass fibre is as reinforcing filler, since glass itself can transmit stress, institute when material is deformed by external force
There are much relations with the power of degree of scatter and the two binding force of the intensity and glass fibre of material in polypropylene matrix.
The present invention is using the surface-treated glass fiber of load nucleating agent as reinforcing filler, after the addition of nucleating agent makes melt blending
Composite modification material have higher crystallinity, evenly tiny crystallization local glass fibre can be promoted more uniformly to be distributed
It is embedded in non-crystalline areas, and the nucleating agent of fiberglass surfacing load can promote matrix polypropylene structure cell perpendicular to glass simultaneously
Side is grown up so that glass has higher bond strength with matrix, so that modified material has higher intensity, pole
The earth extends its application field.

At least one of heat stabilizer, calixarene kind heat stabilizer and dilauryl thiodipropionate heat stabilizer；The light is stablized
Agent is UV light stabilizing agent.
The UV light stabilizing agent is preferably septichen phenyl ester, three nitrogen of 2- (2- hydroxy-5-methyl bases phenyl) benzo
Azoles, 2,4-DihydroxyBenzophenone, ESCALOL 567,2-hydroxy-4-n-octoxybenzophenone, 2- (2-
Two tertiary phenyl of hydroxyl -3,5-) at least one of -5- chlorinations benzotriazole and single benzoic acid resorcinol.
The processing aid is low molecule esters processing aid, metal soap processing aid, the compound esters processing of stearic acid
At least one of auxiliary agent and amides processing aid.
Another goal of the invention of the present invention is to provide a kind of above-mentioned high strength glass fiber reinforced polypropylene compound material
Preparation method, first by glass fibre, alkali compounds and nucleating agent in mass ratio be 100：0.3-2：0.2-1 is put into high mixer
In, it is heated to 40-80 DEG C and is stirred for the 5-30 minutes modified glass-fibers to get area load nucleating agent；Then by polypropylene
Resin, compatilizer, stabilizer, light stabilizer, processing aid are added in mixing apparatus are uniformly mixed according to the ratio；Finally incite somebody to action
The mixture arrived is added from twin-screw extrusion owner's spout, and modified glass-fiber is added from double screw extruder side spout
Enter, through melting mixing, is granulated to obtain composite material.
Further scheme, the melting temperature are 200-270 DEG C.
The present invention is blended double-screw extruding pelletizing technique using conventional melt and prepares composite material, and method of modifying is simply easy
Row is suitble to scale of mass production；
The present invention is using the modified glass-fiber of load nucleating agent as reinforcing filler, since the addition of nucleating agent to melt
Melting the composite modification material after being blended has higher crystallinity, and evenly tiny crystallization local can promote glass fibre more equal
It is distributed evenly and is embedded in non-crystalline areas, make the crystal region uniformity of polypropylene matrix；And modified glass-fiber surface may be used also
Matrix polypropylene structure cell is promoted to be grown up perpendicular to glass side so that glass has higher bond strength with matrix, from
And make modified material that there is higher intensity, greatly extend its application field.
