Description
Technical field
The invention belongs to modified polypropene technical field more particularly to a kind of scraping-resistant polypropylene material and its preparation sides
Method.
Background technology
Polypropylene material is widely used in due to its inexpensive light advantage in inner and outer decorative parts of automobile.But polypropylene material
The scratch resistance of material itself, the especially polypropylene material through talc is poor, and material is in pressing-in force and sliding force or cross
（Side）It can be surrendered under the action of to power, and generate ductility/brittle break, to cause scratch on the surface of product.It is scraping
In trace, uneven surface generates non-uniform light scattering and " scratch whitens ", to limit polypropylene material in scratch resistance
Use at parts that can be more demanding.In order to solve this problem, the method for commonly using addition scratch resistance liniment improves polypropylene
The scratch-resistant effect of material, but traditional scratch resistance liniment is mainly erucyl amide substance and high silicones, this two class
Substance, which is deposited in itself, has the shortcomings of odor profiles heavier, for that in automotive upholstery, can there is the problems such as influencing its VOC, smell.
Invention content
The purpose of the present invention is to provide a kind of scraping-resistant polypropylene materials and preparation method thereof, reach raising polypropylene material
The using effect of polypropylene material is not influenced while material scraping and wiping resistance performance.
The technical scheme is that：A kind of scraping-resistant polypropylene material is prepared by weight by following components：

ZrB2（Zirconium diboride）0.1-1 parts.
Further preferably：The polyacrylic melt flow rate (MFR) is temperature is 230 DEG C, pressure is 2.16kg's
Under the conditions of by the melt quality of standard mouth mold be 0.1-100g/10min.
The heat stabilizer is one kind or more in sub- phenolic thermostabilizers, amine thermostabilization phosphoric acid ester heat stabilizer
The combination of kind.
Described Asia such as four [β-(3,5- di-tert-butyl-hydroxy phenyls) propionic acid] pentaerythritol ester of phenolic thermostabilizers
（C73H108O12）（Abbreviation antioxidant 1010）；Amine thermostabilization phosphoric acid ester heat stabilizer has three [2.4- di-tert-butyl-phenyls] sub-
Phosphate（C42H63O3P）（Abbreviation irgasfos 168）.
The lubricant is one in metal soap lubricant, the compound ester lubricant of stearic acid and amide series lubricant agent
Kind or a variety of combinations.
The metal soap lubricant has PbSt；The compound ester lubricant of stearic acid has N, N '-ethylene bis stearamides（Letter
Claim EBS）.
The coupling agent is a kind of in silane coupling agent or titanate coupling agent.
The silane coupling agent has, and its chemical name is γ-aminopropyl triethoxysilanes（Abbreviation KH-550）；Metatitanic acid
Ester coupling agent has three oleoyl isopropyl titanates（Abbreviation OL-T951）, γ-aminopropyl triethoxysilane（Abbreviation KH-
550）, γ-methacryloxypropyl trimethoxy silane（Abbreviation KH-570）.
The ZrB2 is the powder of C32 type hexagonal structures, and high temperature resistant, intensity are high, and anti-oxidant under high temperature.
The grain size of the talcum powder is 100-1000 μm.
It is a further object to provide a kind of preparation methods of scraping-resistant polypropylene material, by polypropylene, silane
Screw Extrusion is added from the main spout positioned at one end of screw extruder in coupling agent, heat stabilizer, lubricant, white oil and ZrB2
In machine, melt blending is carried out, extruding pelletization obtains scraping-resistant polypropylene material；The draw ratio of the screw extruder is 35-56:
1, temperature is 170-250 DEG C.
The present invention's has the following advantages that compared with prior art：
1, of the invention by inorganic material ZrB2It is added into polypropylene material as scratch resistance liniment, and overcomes traditional scraping
Agent is to reach estimated scratch-resistant effect, needs higher additive amount, under long-time high temperature ageing environment, is easily precipitated and migrates to table
Face and the problems such as existing smell, VOC, can be used for automotive upholstery.
2, due to ZrB2With C32 type hexagonal structures, hardness is up to 22GPa, when additive amount is only 0.5% or so, i.e.,
Preferable scratch-resistant effect is can get, its five fingers scrapes level-one after tested.
3, in addition, due to ZrB in the present invention2Additive amount it is less, so being influenced on polypropylene material other performances smaller.
