Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0026] This case proposes an ITO-specific PP protective film formulation of an embodiment, including the following materials by weight:

[0027]

[0028] Wherein, in the polyethylene octene co-elastomer (POE), the content of octene is 37wt%-41wt%. In the POE used in this case, it is only necessary to limit the content of octene, and there is no need to specifically limit the type and composition of its block distribution. All commercially available products with an octene content within the set range can meet the requirements of this case. The coiled structure of soft chains in octene can not only improve the temperature resistance of the film but also adjust the viscosity of SEBS. However, the content of octene in POE should be limited, otherwise it will seriously affect its own ...

Abstract

The invention discloses a special PP protecting membrane formula for ITO. The special PP protecting membrane formula comprises the following raw materials in parts by weight: 70-80 parts of polypropylene, 1-5 parts of a polyethylene octylene co-elastomer, 5-15 parts of SEBS, 0.1-0.3 part of an antioxidant and 2-3 parts of poly alpha-methyl styrene resin, wherein the content of octylene in the polyethylene octylene co-elastomer is 37-41wt%. As SEBS is adopted as a self-adhering layer, the temperature resistance of polypropylene is improved and the viscosity of SEBS is adjusted by adding POE, and the softening point of SEBS is increased and separation of oil components in SEBS can be controlled by adding the poly alpha-methyl styrene resin, the problems that a coated protecting membrane has residual adhesives, is low in viscosity and poor in temperature resistance, and the like can be solved; as PP is taken as a substrate in the formula, the temperature resistance of the protecting membrane can be effectively improved.

Description

technical field [0001] The invention relates to a formula of a polymer film, in particular to a formula of a special PP protective film for ITO. Background technique [0002] At present, the ITO (indium tin oxide) special protective films on the market generally have problems such as insufficient self-adhesive force, poor temperature resistance and poor weather resistance. When coating these protective films, the residual glue rate is high. The key to solving these problems lies in whether an economical and reasonable protective film formula can be found, so that it can easily overcome these technical defects without large-scale changes to the existing process. Contents of the invention [0003] In view of the above-mentioned technical defects, the object of the present invention is to provide a formula for PP protective film dedicated to ITO. [0004] Technical scheme of the present invention is summarized as follows: [0005] A special PP protective film formulation fo...
