Embodiment 3
The experimental group for the different proportion that the present embodiment is proposed using embodiment 2 is experimental subjects, for test sample made from it
Physicochemical property is researched and analysed, and specific sample preparation methods are as follows:
Each component weight is weighed according to above ratio, is added in high-speed mixer and mixes in sequence in addition to maleic anhydride
1-3min, maleic anhydride are heated to complete molten condition, in the case where high mixer stirs at low speed state, slowly uniformly fall from small feed opening
Enter in dry-mixed machine, continues to stir at low speed 2min, blowing.Uniformly mixed material is added in equidirectional parallel double-screw extruder, melts
Melting extrusion temperature is 200-250 DEG C, and specific properties test result is as shown in table 2.
2 experimental result list of table
| Project | Experimental group 1 | Experimental group 2 | Experimental group 3 | Experimental group 4 |
| Melt index | 1.0 | 1.4 | 2.0 | 2.2 |
| Tensile strength | 15.1 | 15.4 | 15.3 | 15.3 |
| Elongation at break | 460 | 510 | 530 | 560 |
| Vicat softening point | 112 | 114 | 114 | 114 |
| Simply supported beam notch impact strength | 16.5 | 17.2 | 18.6 | 19.2 |
| Simply supported beam unnotched impact strength | > 100 | > 100 | > 100 | > 100 |
| With 180 ° of peel strengths of aluminium flake | 220 | 336 | 308 | 282 |
According to 2 data of table, it can be seen that from experimental group 1 to experimental group 4, the melting means of sample is gradually risen, elongation at break, freely-supported
Beam notch impact strength is also gradually increased.The analysis of causes are as follows: from experimental group 1 to experimental group 4, the additive amount of maleic anhydride is gradually
It reduces, which results in the grafting rates of product (or degree of cross linking) to gradually decrease, i.e. winding between strand is less, steric hindrance
Less, melting means, elongation at break, the simply supported beam notch impact strength for having eventually led to product are improved.
According to 2 data of table, it can be seen that from experimental group 1 to experimental group 4, the peel strength (i.e. bonding force) of sample is in first to increase
The trend reduced after big.The analysis of causes are as follows: in experimental group 1, the additive amount of maleic anhydride is most, and product is caused to have portion in the reaction
Divide cross-linking reaction, cross-linking reaction has negatively influencing to the bonding force of product, to affect further increasing for its peel strength；It is real
It tests in group 2, the additive amount of maleic anhydride is moderate, and graft reaction is more abundant, and cross-linking reaction is got back rationally to control and (is crosslinked anti-
Should be few), therefore peel strength is relatively high；In experimental group 3, the additive amount of maleic anhydride is minimum, and almost all is grafting in reaction
Reaction, but since maleic anhydride additive amount is few, graft reaction is not up to the limit, and grafting rate is relatively low, therefore peel strength experimental group 2 has
Declined.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.
