Performance test
The enhancing PP composite material of mineral filler prepared by embodiment 1-6 and comparative example 1-3 is molded into mark according to national standard
Quasi- test bars carry out mechanical property dependence test.
Notch shock test reference national standard GB/T 1843 is carried out；Extension test is carried out with reference to national standard GB/T 1040；Bending
Test reference national standard GB/T 9341 is carried out；Thermal deformation (0.45MPa/6.4mm) test reference national standard GB/T1634 is carried out；It is fire-retardant
Performance is tested according to UL94 (1.6mm) flammability test standard；Shrinking percentage test reference national standard GB/T 15585 is carried out, choosing
With 150 × 100 × 3.2mm mold；Glossiness test reference national standard GB/T 9754 is carried out.Glossiness is to show that finished surface is thick
One index of rough degree, usually, the better product of glossiness, surface is more smooth, and appearance is better, therefore glossiness is normal
For characterizing the appearance quality of product surface.
The test result of embodiment 1-6 and comparative example 1-3 are as shown in table 2.
Table 2
As can be seen from Table 1 and Table 2, the composite material that 1-6 of the embodiment of the present invention is provided has good appearance, machine simultaneously
Tool performance, heat resistance and low-shrinkage are suitable for injection molding technique.Compared with Example 3, impact property is especially for comparative example 1
It is that dimensional stability has larger decline, this illustrates the PP and Lu of selection compounding2W3O12For the toughness and dimensional stability of material
There can be active influence.Compared with Example 3, rigidity and appearance have larger decline to comparative example 2, this is because in copolymerization PP resin
PE toughening containing 1%~5% declines material stiffness, Lu2W3O12For the opposite spherical junctions with barium sulfate of orthorhombic forms structure
There is structure stronger photoextinction appearance glossiness is decreased obviously, and its special anisotropy negative expansion performance assigns
The fabulous dimensional stability of material；Compared with Example 3, the curved impact property and glossiness of comparative example 3 are slightly higher for comparative example 3,
And other machinery performance, heat resistance, fire-retardant and dimensional stability are lower, this is because non-functional filler is to PP material knot
The destruction of brilliant process and the heterogeneous nucleating effect of nucleating agent make its glossiness and impact strength keep higher, and make other machinery
Performance, heat resistance and dimensional stability decline.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
