Embodiment 1
[0048] The HDPE / POE-g-MAH / mesoporous molecular sieve blend material described in this example is composed of HDPE, POE-g-MAH, mesoporous molecular sieve, antioxidant and lubricant. The feature of this example is that toughening materials and reinforcing materials are introduced into HDPE, so that HDPE can reach various performance indicators that can be used as engineering plastics. According to step (1), use brand 8150 POE for proportioning: 60 parts of HDPE, 10 parts of POE-g-MAH, 30 parts of mesoporous molecular sieve, 0.15 part of antioxidant, and 0.15 part of lubricant. Concrete preparation steps are as follows:
[0049] Manufacture POE-g-MAH from step (2); carry out the proportioning experiment of the obtained materials according to Table 1 in step (6); operate the obtained materials according to steps (7) and (8), and carry out the obtained materials ( 9) Operate, derive data, record and analyze. The performance test results of the HDPE / POE-g-MAH / mesoporous molecular ...
Embodiment 2
[0051] The composition of this example is consistent with that of Example 1. The brand is 8150 POE for proportioning: 54 parts of HDPE, 10 parts of POE-g-MAH, 36 parts of mesoporous molecular sieve, 0.15 part of 1010, and 0.15 part of OPE. The difference between the composition of this example and Example 1 is that 54 parts of HDPE and 36 parts of mesoporous molecular sieves are used.
[0052] The preparation method and performance testing standard of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The performance test results of the HDPE / POE-g-MAH / mesoporous molecular sieve blend material obtained in this example are shown in Table 2.
Embodiment 3
[0054] The composition of this example is consistent with that of Example 1. The brand is 8150 POE for proportioning: 50 parts of HDPE, 10 parts of POE-g-MAH, 40 parts of mesoporous molecular sieve, 0.15 part of 1010, and 0.15 part of OPE. The difference between the composition of this example and Example 1 is that 50 parts of HDPE and 40 parts of mesoporous molecular sieves are used.
[0055] The preparation method and performance testing standard of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The performance test results of the HDPE / POE-g-MAH / mesoporous molecular sieve blend material obtained in this example are shown in Table 2.

Abstract
The present invention relates to a composition of HDPE / POE-g-MAH / mesoporous molecular sieve blended material and a preparation method thereof. The HDPE / POE-g-MAH / mesoporous molecular sieve blended material is prepared by the following components according to a certain weight proportion: 50%-60% of HDPE, 30%-40% of mesoporous molecular sieve, 10% of POE-g-MAH, 0.15% of anti-oxidant (1010), and 0.15% of lubricant (OPE). The composition of HDPE / POE-g-MAH / mesoporous molecular sieve blended material can effectively settle the following defects in use: easy deformation, easy rupture, short service life, etc. The adding of the self-made POE-g-MAH reduces tearing phenomenon caused by non-enough toughness in a use process to a certain degree. The adding of the lubricant OPE improves machining performance of the HDPE / POE-g-MAH / mesoporous molecular sieve blended material. The composition can be used for the HDPE(high density polyethylene) / RHDPE(regenerable high density polyethylene) / POE-g-MAH / mesoporous molecular sieve blended material of engineering plastics such as tube.
Description
technical field [0001] The invention relates to a composition of a blend material and a preparation method thereof, in particular to a composition of a HDPE / POE-g-MAH / mesoporous molecular sieve blend material and a preparation method thereof. Background technique [0002] HDPE (high-density polyethylene) resin material has outstanding physical and mechanical properties, chemical stability and excellent electrical insulation, and has a wide range of uses in agriculture, defense industry and other fields. HDPE used as a pipe is increasingly favored by people because of its excellent temperature resistance, wear resistance, corrosion resistance, non-toxicity, light weight, low price, finished product manufacturing and use, and easy installation and maintenance procedures. At present, HDPE is widely used in various aspects, and has penetrated into almost all aspects of life, especially in the application of pipes, which has reached the second place in the use of plastic pipes, s...
