Description
Technical field
The invention belongs to polypropylene material production technical field, improve the original deficiency of polypropylene.Produce and meet
The product of social demand.
Background technology
Polypropylene (PP) is nonpolar crystalline plastics, is one of five major class general-purpose plastics, raw material supplied materials is abundant,
It is cheap, easily processed into type etc., therefore purposes is widely.Although polypropylene has many merits,
But, there is also some shortcomings part.Maximum shortcoming is poor cold resistance.Low temperature is easily broken, and shrinkage factor is big,
Creep resistance is poor, and product size stability is poor, mutability.Hollow glass micropearl is contained within gas, heat conduction system
Number low-quality is gently and surface is smooth etc..The good polymer of insulation mechanical property can be prepared.
The content of the invention
It is an object of the invention to provide a kind of mechanical property for not influenceing material, the polypropylene of environmental protection is dedicated modified
Material.Hollow glass micropearl RPP material, is made up of following weight ratio raw material：
Polypropylene：70~80；

Hollow glass micropearl：10~30；
Dispersed lubricant：0.5~1.5；
Dispersant：0.5~1.5.
Heretofore described antioxidant is the copolymer of ethylene-octene, and the dispersant is technical white oil 10#,
The dispersed lubricant is TAS-2A.
The preparation method of the hollow glass micropearl RPP material is：First by hollow glass micropearl and silicon
Alkane coupling agent carries out surface activation process, then above-mentioned various raw materials are dry-mixed 3-5 minutes in super mixer,
It is placed in again in double screw extruder through melting extrusion, cooling, pelletizing, packed products；Wherein, double spiral shells
The area's temperature of bar extruder one is 90-100 DEG C, and 2nd area are 150-180 DEG C, and 3rd area are 200-210 DEG C, and 4th area are
