The effect of p-t-butyl phenol is anti-oxidant, the important role in intermediate layer, and it is connecting layer, needs to take into account top layer With the matching degree of internal layer, therefore, slightly deviation larger to the design difficulty of Interlayer Formulation will cause the self-adhesion of three-decker Film produces differentiation, can be identified by naked eyes, also, can be to horizontal, longitudinal tensile strength of film and punctured resistance Impact.The advantage of p-t-butyl phenol is its strong adaptability, and compatibility is more gentle, used in herein to entirely filling a prescription not Rejection can be brought, and according to conventional phenols oxidant, such as antioxidant 1010, then can cause the discomfort of system, especially It is to produce certain rejection with barium stearate, specifically in parameter show as horizontal, longitudinal tensile strength and The decline of punctured resistance.ATBC is here a kind of light stabilizer, for improving self-adhesive film under strong illumination Stability.Titanium dioxide effect here is not colouring agent, but improves cracking resistance of the intermediate layer under solar radiation, anti- Discoloration, anti-stretching, extension and acid-proof alkaline.

Internal layer includes the material of following weight portion:

Internal layer mainly provides adhesive property, but the characteristics of based on three-layer extrusion film, the formula of internal layer is also required to and overall phase Matching.Ethylene bis stearamide is a kind of internal lubrication prescription, for improving the flow rate of melt, improves demoulding and fineness. Ethylene-propylene copolymer is used for the height of regulation system viscosity, but the original intention of this regulation is in order that interior coating systems can be with Other two systems think matching, therefore, ethylene-propylene copolymer viscosity adjustment effect here is actually for system The done accommodation of compatibility issue, but this regulatory function is the proprietary feature of ethylene-propylene copolymer, other lists The effect of one polymer or the copolymer that is made up of other materials then without this effect or regulation is preferable not enough.When So, the copolymerization type of ethylene-propylene copolymer then need not be restricted, and random copolymerization is good, and block copolymerization also may be used.Ethene-the third The preparation method of alkene copolymer then belongs to prior art, and this case will not be described here.

As another embodiment of this case, wherein, in top layer, the number-average molecular weight of polyethylene is both preferably 10000~ 15000g/mol。

As another embodiment of this case, wherein, in intermediate layer, the number-average molecular weight of polyethylene is preferably 20000~ 25000g/mol。

As another embodiment of this case, wherein, in ethylene-propylene copolymer, ethylene contents are 55~60wt%.Certainly, For the pursuit of the best bond effect to the self-adhesive film, the content of ethene still should be somewhat limited, studies surface, second Alkene content can make internal layer obtain optimum adhesive property in the range of 55~60wt%, not only, and can also take into account internal layer with The consistency problem of interbed, the performance that film has been effectively ensured is unaffected.Additionally, ethylene contents are controlled in 55~60wt% scopes It is interior, moreover it is possible to ensure that ethylene-propylene copolymer has good compatibility and is uniformly dispersed with polyethylene octene elastomer (POE) Property.

As another embodiment of this case, wherein, the number-average molecular weight of ethylene-propylene copolymer is preferably 9000~ 10000g/mol。

As another embodiment of this case, wherein, in polyethylene octene elastomer, the content of octene be 15wt%~ 18wt%.Octene content is between 20wt%~30wt% in current POE on the market, but it is this existing to test discovery POE proportionings are not particularly well-suited for the system of this case, and it can not be perfectly combined with this case additive therefor, therefore this case Breakthroughly the content of octene some downwards are carried out into, while partial cohesive and impact resistance is sacrificed, have taken into account whole The harmony of individual formula so that the formula can produce preferable Forming Quality when die head is extruded, obtains while also unexpected Significantly improving in terms of heatproof air aging performance.But octene also have it value be located, therefore its content can not under Adjust excessive, generally speaking the content of octene should be limited in above-mentioned scope.

As another embodiment of this case, wherein, the number-average molecular weight of polyethylene octene elastomer is preferably 5000~ 6000g/mol。

As another embodiment of this case, wherein, top layer is also including the boron oxide of 0.4~0.5 weight portion.Boron oxide is used to assist With the weatherability for improving top layer, it can be by increasing it in body with butyl p-hydroxybenzoate in the form of electronics is to coordination Stably dispersing degree in system, while it can produce synergistic effect with butyl p-hydroxybenzoate, further improves the anti-ageing of top layer Change and decay resistance.
