A felt adhesive, its preparation method and application
PendingCN122082266AExcellent adhesionGuaranteed to stick firmlyCovering/liningsSynthetic resin layered productsPolyesterFiber
This invention discloses a felt adhesive, its preparation method, and its application, belonging to the field of adhesive technology. The felt adhesive comprises a felt base layer and an adhesive layer in a mass ratio of 8:2. The felt base layer is made of 85-90% polyester fiber and 10-15% low-melting-point fiber, while the adhesive layer is a compound of 70-85% hot melt adhesive and 15-30% water-based adhesive. The preparation method includes three steps: felt base layer preparation, adhesive layer preparation, and compounding. The process is simple, highly efficient, and suitable for large-scale industrial production. This felt adhesive solves the shortcomings of existing wall writing materials, such as poor adhesion, inability to be re-attached, significant damage to the wall surface, poor writing feel, and narrow applicability. It achieves a balance between strong adhesion and re-attachment, with minimal damage to the wall surface. It can be directly applied to various wall surfaces and can also be used in combination with magnetic writing materials, making it suitable for various scenarios such as children's rooms, offices, and kindergartens.
