As can be seen from the examples, DuPont 9020 is selected as the toughening agent with the best effect. The comparative examples respectively select toughening agent combination 1: LDPE 7042: the weight ratio of the Pe grafted maleic anhydride LM300 is 10: 10; toughening agent combination 2: POE875 l: the weight ratio of POE grafted maleic anhydride 5805L is 4: 9; toughening agent combination 3: AX 8900: the weight ratio of POE grafted maleic anhydride 5805L is 4: 9 in the presence of a surfactant. The heat distortion temperature is low, and the requirement of heat resistance cannot be met.
From comparative example 1 and example 3, it can be seen that the thermal deformation temperature is 10.2 ℃ higher after the nucleating agent is added, and comparative example 3 and comparative example 5 can also be seen that the thermal deformation temperature is 8 ℃ higher after the nucleating agent is added, but the notch impact strength is reduced and the toughness is deteriorated; as can be seen from examples and comparative example 6, increasing the amount of nucleating agent from 0.1 to 0.5 did not result in a significant increase in the heat distortion temperature, but the notched impact decreased and the toughness deteriorated whereby it was seen that the amount of nucleating agent added was neither used nor too high, and the preferred toughening agent of the present invention (DuPont 9020): nucleating agent (bronugeman P22) ═ 5:0.1 (weight ratio).
It can be seen from comparative examples 1-4 that, when the amount of the toughening agent (DuPont 9020) in comparative example 1 is 5 parts, the toughening effect is almost the same as that of comparative examples 2, 3 and 4, the addition amount is obviously less than that of comparative examples 2, 3 and 4, the melt index is higher, the fluidity is good, and the heat distortion temperature can reach 255.2 ℃, while the heat distortion temperatures of comparative examples 2, 3 and 4 are only 145 ℃, 163 ℃ and 168 ℃.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
