Description

Technical Field

[0001] The utility model relates to the technical field of solvent-free composite, in particular to a solvent-free coating composite system. Background Art

[0002] A solvent-free laminating machine is a method of laminating two or more substrates together using a two-component or one-component solvent-free adhesive. In the prior art, an adhesive is set between two adjacent substrates during lamination. The adhesive is usually first evenly coated on one of the substrate surfaces, and the two substrates are bonded together by a laminating mechanism. However, when this technical solution uses a two-component adhesive, since the two-component adhesive is divided into two types of adhesive, A glue and B glue, during the production process, the two glues need to be pre-mixed in proportion for reaction when used. Using one type of adhesive alone cannot achieve the desired effect. Therefore, in order to ensure uniform mixing of the two-component adhesive, A and B glues are generally pre-mixed and then applied to the substrate. However, in this technical solution, A glue and B glue will begin to react after premixing, and the reaction time is too fast to achieve uniform coating. The current technical means to solve this problem is to apply A and B glues on two substrates respectively, and then composite the substrates together, so that A and B glues react during the composite process. Compared with premixing A and B glues and then applying them on the film, it not only reduces production costs but also improves processing efficiency. However, in the prior art, after A and B glues are evenly coated on the substrate surface, when the two substrates are composited, A and B glues on the surface of the coated surface first contact and mix with each other to react, making it difficult for A and B glues below the surface to mix evenly, thereby affecting the composite effect of the substrate. Utility Model Content
