Abstract

The invention discloses a TPU-attached silicone rubber zipper film. The TPU-attached silicone rubber zipper film includes a preprocessed TPU thin film and a silicone rubber layer, and the TPU thin film is attached to the silicone rubber layer; the silicone rubber layer is prepared from, by weight, 100-120 parts of vinylsiloxane rubber A component, 120-150 parts of vinylsiloxane rubber B component,30-50 parts of vinyl silicone oil, 10-30 parts of color paste pigment and 3-10 parts of silane coupling agent. The invention further discloses a coating technology and application of the TPU-attachedsilicone rubber zipper film. The TPU-attached silicone rubber zipper film is simple in technology, low in cost and high in production efficiency; the TPU-attached silicone rubber zipper film has thecharacteristics of a TPU material and the advantages of silicone rubber, wherein the TPU material is characterized by being easy to process and capable of post-shaping, and the silicone rubber has theadvantages of being good in weather resistance, hydrolysis resistance, high-temperature resistance, low-temperature resistance and color fastness and easy to clean. A prepared waterproof zipper madeof the TPU-attached silicone rubber is good in waterproof performance, low in cost and long in service life.

Description

technical field [0001] The invention relates to the technical field of zipper film manufacturing, in particular to a TPU-bonded silicone rubber zipper film, a coating process and its application. Background technique [0002] Zipper is a product that is often used in people's daily life, and is often used at the interface or seal of bags, clothing, and shoes. The zipper sliders and chain teeth of traditional zippers are mostly made of metal, plastic and other materials. These zippers themselves do not have waterproof function and often bring a lot of inconvenience to users in rainy weather. [0003] In order to overcome this problem, the industry has designed and developed zippers with a waterproof function, coating a layer of PU resin on the surface of the zipper, or attaching a layer of TPU film by high-temperature hot pressing. For example, the Chinese utility model patent with the publication number of 205390571U discloses a high-temperature and wear-resistant TPU film ...
