Performance evaluation mode and implementation standard:
By the particulate material prepared by above-mentioned comparative example 1~3 and Examples 1 to 6, in 90~100 DEG C of convection oven
When drying 2~3 is small, standard batten is then made in dried particle on injection (mo(u)lding) machine for testing.
Density measurement：It is carried out according to ISO 1183-1；Tensile property is tested：It is carried out by ISO 527-2 standards, tensile speed
For 50mm/min；Bending property is tested：It is carried out by 178 standards of ISO, rate of bending 2mm/min；Notch impact strength is tested：
It is carried out by 180 standards of ISO；The pressure mottling resistance of material can be tested：According to 3974 standards of PV, according to material surface before and after experiment
Glossiness changes DGG to judge.The numerical value of DGG is smaller, represents that the pressure mottling resistance of material can be better.
The properties test result of embodiment and comparative example see the table below：
1~3 the performance test results of 1 Examples 1 to 6 of table and comparative example
As can be seen that substituting talcum powder using 5 parts of micas from the comparison of embodiment 3 and comparative example 1,2,3, DGG can drop
Low 0.2, the pressure mottling resistance of polypropylene material can significantly improve, and meet the requirement of popular DGG≤0.6.From embodiment 4,5,6 with it is right
During in the comparison of ratio 3 again it can be seen that using mica partial alternative talcum powder, the pressure mottling resistance of material can greatly improve,
And with the increase of substitution ratio, pressure mottling resistance can be obviously improved.As can be seen that high-density polyethylene from the comparison of embodiment
The increase of alkene content improves the pressure mottling resistance energy of material to a certain extent, mainly since high density polyethylene (HDPE) can make poly- third
Alkene crystallization refinement, so as to reduce the depth of cup of material.In addition the polypropylene material that prepared by the present invention has excellent resistance to compression trace
While performance, the mechanical property of material is substantially unaffected.
The foregoing is merely the embodiment of the present invention, but protection scope of the present invention is not limited thereto, the skill of this field
Art personnel, which should be appreciated that, to be modified or replaced equivalently the technical solution of invention, without departing from inventive technique scheme
Objective and scope, be covered by the protection scope of the present invention.
