Problems solved by technology

Rubber-type pressure-sensitive adhesives generally use gasoline, toluene, etc. as solvents, which are very dangerous and polluting; silicone-type pressure-sensitive adhesives are generally two-component or three-component, and the curing temperature is relatively high (generally higher than 130°C ), not suitable for PE protective film; water-based acrylic pressure-sensitive adhesive has obvious advantages in terms of safety, environmental protection and use, but due to the large content of small molecules and insufficient cohesive force, it is easy to cause cohesive damage and mixing when used Destruction and other failure forms

Abstract

The invention provides a metal section bar protection film and a production method thereof. An emulsion pressure-sensitive adhesive has the characteristics of large cohesion, small content of micro-molecules, certain initial viscosity, good persistent viscosity, stable mechanical performances and stable thermal performance, the use performances are not affected after the emulsion pressure-sensitive adhesive is stored at normal temperature for 6 months, the coating film formation performance is good, and hole shrinkage and crack phenomena does not exist in the coating process; the protection film produced by using the pressure-sensitive adhesive has the advantages of good coating performance and peelability, good adhesive surface film formation uniformity, no hole shrinkage or cracking, high cohesion, and suitableness for high-surface energy surface coating; and the protection film can be applied to coating of micro-porous anodized aluminum and stainless steel plate surfaces without residual adhesive or mottles.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a protective film for metal profiles and a preparation method thereof. Background technique [0002] During the production and transportation of aluminum profiles, it is easy to affect the surface quality of aluminum profiles due to interactions such as collision and extrusion. Therefore, aluminum profiles need to be covered with a protective film for surface protection from production to installation. After anodic oxidation, the surface of alumina produces a pore structure with a pore size of tens of nanometers, and the surface energy is very high. Therefore, a sealing process is required to reduce the surface energy. However, some micropores will still remain after the sealing process is completed. At this time, when the pressure-sensitive adhesive protective film is attached, the protective film will fail because the force between the protective film and the surface o...
