Detection method
Referring to GB 9641-1988, the tensile properties of the low density, high pressure polyethylene closed cell foam sheets prepared in examples 1-10 and comparative examples 1-4 were tested and the specific test results are shown in Table 2 below:
TABLE 2 Performance test of Low Density high pressure polyethylene closed cell foam panels
As can be seen from Table 2, the low-density high-pressure polyethylene closed-cell foam plastic plate prepared by the embodiment of the application has the tensile strength of more than or equal to 3.14MPa, higher tensile strength and better mechanical property.
As can be seen in combination with example 1 and comparative examples 1-4 and with table 2, the low density, high pressure polyethylene closed cell foam panels made in example 1 have much greater tensile strength than comparative examples 1-4, probably because: comparative example 1 a low density high pressure polyethylene closed cell foam board was made from conventional low density high pressure polyethylene; comparative example 2 a low density high pressure polyethylene closed cell foam board comprised no epoxy modified polyurethane in the raw material; comparative example 3 a low density high pressure polyethylene closed cell foam board comprising no cardanol as a raw material; comparative example 4 a low density high pressure polyethylene closed cell foam board was made from conventional polyurethane. In the embodiment 1, silane coupling agent grafted modified polyethylene, epoxy modified polyurethane and cardanol are used as raw materials to prepare a closed-cell foam plastic plate with good mechanical properties, and the specific principle is as follows: the active hydroxyl, epoxy and urethane bonds on the three raw materials can be crosslinked/bonded with each other to form a resin network crosslinked structure; in addition, the cardanol also contains a rigid benzene ring, and the existence of the rigid benzene ring improves the mechanical properties of the closed-cell foam plastic plate. In conclusion, the silane coupling agent grafted modified polyethylene, the epoxy modified polyurethane and the cardanol are matched with each other, so that the mechanical properties of the polyethylene closed-cell foam plastic plate are improved together.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
