Embodiment 1
[0028] The high-temperature-resistant film of this embodiment includes three parts: an outer layer, a middle layer and an inner layer. The weight of the outer layer accounts for 10% of the total weight of the film, the weight of the middle layer accounts for 60% of the total weight of the film, and the weight of the inner layer accounts for 30% of the total weight of the film. , where, by weight percentage,
[0029] The raw materials for the preparation of the outer and inner layers are PP M800E;
[0030] The raw material for the middle layer is composed of 80% MDPE 5400 and 20% LDPE TN00.
[0031] The preparation method of the high temperature resistant film of the present embodiment is as follows:
[0032] 1) mixing materials, mixing the preparation raw materials of the middle layer of the formula amount to prepare the middle layer raw material mixture of the high temperature resistant film;
[0033] 2) batching, the middle layer raw material mixture of the high temperature ...
Embodiment 2
[0036] The high-temperature-resistant film of this embodiment includes three parts: an outer layer, a middle layer, and an inner layer. The weight of the outer layer accounts for 30% of the total weight of the film, the weight of the middle layer accounts for 50% of the total weight of the film, and the weight of the inner layer accounts for 20% of the total weight of the film. , where, by weight percentage,
[0037] The raw materials for the preparation of the outer and inner layers are PP M800E;
[0038] The raw material for the middle layer is composed of 60% MDPE 5400 and 40% LDPE TN00.
[0039] The preparation method of the high temperature resistant film of this embodiment is the same as that of Embodiment 1, and will not be repeated here.
Embodiment 3
[0041] The high-temperature-resistant film of this embodiment includes three parts: an outer layer, a middle layer and an inner layer. The weight of the outer layer accounts for 30% of the total weight of the film, the weight of the middle layer accounts for 60% of the total weight of the film, and the weight of the inner layer accounts for 10% of the total weight of the film. , where, by weight percentage,
[0042] The raw materials for the preparation of the outer and inner layers are PP M800E;
[0043] The raw material for the middle layer is composed of 70% MDPE 5400 and 30% LDPE TN00.
[0044] The preparation method of the high temperature resistant film of this embodiment is the same as that of Embodiment 1, and will not be repeated here.
