Problems solved by technology

However, when the glass plate needs to be actually used after it has been shipped and transported, it is necessary to tear off the protective film on the outer surface of the glass plate. Because the existing adhesive has a relatively high adhesion to the polymer wear-resistant substrate and the glass plate, and the flow Strong resistance, making it difficult to remove the protective film from the glass plate and leaving adhesive residue

Embodiment approach

[0028]In one embodiment, the thickness of the wear-resistant polymer substrate is 4 μm to 8 μm, of course, in other embodiments, the thickness of the wear-resistant polymer substrate may also be other values. However, when the thickness of the wear-resistant polymer base material is 4 μm to 8 μm, the wear-resistant polymer base material is sufficient to protect the glass plate well during the long-distance shipment and transportation of the glass plate and has good adhesion to the glass plate. better. Taking the polyethylene terephthalate substrate as an example for the polymer wear-resistant substrate, if the thickness of the polyethylene terephthalate substrate is too high, it will increase raw material costs and reduce production efficiency, and will Reduce its softness and light transmittance; if the thickness of the polyethylene terephthalate substrate is too low, it will increase its production difficulty and reduce production efficiency, and will reduce its mechanical s...

Abstract

The invention relates to the field of protective films, and provides a protective film for delivery of glass cover plates with low film tearing force. The protective film comprises a high-molecular wear-resistant base material, an acrylic low-viscosity adhesive layer and an anti-fouling isolation film, wherein one side face of the high-molecular wear-resistant base material is coated with the acrylic low-viscosity adhesive layer, and the anti-fouling isolation film adheres to the side face, away from the high-molecular wear-resistant base material, of the acrylic low-viscosity adhesive layer;the acrylic low-viscosity adhesive layer comprises, by mass, 36.0-50.0 parts of an acrylic acid copolymer, 0.3-0.6 part of an initiator, 50.0-80.0 parts of a diluent and 0.5-3 parts of a curing agent.The protective film has excellent wear resistance, weather resistance, ageing resistance and light transmittance and low film tearing force; the acrylic acid low-viscosity adhesive layer can still firmly adhere to the high-molecular wear-resistant base material in the long-distance delivery and transporting process; the protective film for delivery of the glass cover plates can be torn off easilyfrom the glass plates, and residual glue cannot be left.

Description

technical field [0001] The invention relates to the field of protective films, in particular to a protective film for shipping glass cover plates with low tearing force. Background technique [0002] A large number of glass plates will be worn and scratched due to mutual friction or impact during long-distance shipping and transportation. Therefore, an excellent wear-resistant and weather-resistant performance, anti-aging performance and a light and thin protective film for glass cover shipments are required. Laying On the outer surface of the glass plate, the glass plate is well protected during long-distance shipment and transportation. Common light and thin protective films have poor wear resistance, weather resistance and aging resistance, and cannot withstand tests such as light, cold and heat, wind and rain, bacteria, etc. for a long time. [0003] In order to solve this problem, people try to improve the ordinary substrate of the protective film into a polymer wear-r...
