技术领域technical field
本实用新型涉及离型膜技术领域，特别涉及一种稳定性好的低离型哑光离型膜。The utility model relates to the technical field of release films, in particular to a low-release matte release film with good stability.
背景技术Background technique
离型膜是指表面具有分离性的薄膜，离型膜与特定的材料在有限的条件下接触后不具有粘性，或轻微的粘性。离型膜又称剥离膜、隔离膜、分离膜、阻胶膜、离形膜、薄膜、塑料薄膜、掩孔膜、硅油膜、硅油纸、防粘膜、型纸、打滑膜、天那纸或离型纸等。The release film refers to a film with a separable surface. The release film is not sticky or slightly sticky after being in contact with a specific material under limited conditions. Release film is also known as peeling film, isolation film, separation film, barrier film, release film, film, plastic film, hole masking film, silicone oil film, silicone oil paper, anti-adhesive film, type paper, slip film, Tianna paper or Release paper, etc.
目前离型膜广泛应用于电子胶粘剂、印刷线路板、手机等领域，其独特的低表面涨力使其自身不易附着其他材料。随着经济的发展，离型膜的应用越来越广泛。普通的离型膜主要是由基膜和与该基膜相贴合的纸组成。采用纸材料制成的离型膜，其的稳定性较差，导致加工性能不太理想，而且在与FPC柔性电路板相贴合，由于FPC柔性电路板本身质软易弯折变形，影响到模切精度。At present, the release film is widely used in electronic adhesives, printed circuit boards, mobile phones and other fields. Its unique low surface tension makes it difficult to adhere to other materials. With the development of economy, the application of release film is more and more extensive. Ordinary release film is mainly composed of base film and paper attached to the base film. The release film made of paper material has poor stability, which leads to unsatisfactory processing performance, and when it is attached to the FPC flexible circuit board, because the FPC flexible circuit board itself is soft and easy to bend and deform, it affects the Die-cutting precision.
