Abstract

The invention discloses thermoplastic electrostatic flocking fabric as well as a preparation method and application thereof. The electrostatic flocking fabric is composed of a surface layer, a middle layer and a bottom layer, wherein the surface layer is fiber fluff, the middle layer is a glue curing layer, and the bottom layer is base cloth; the glue curing layer is electrostatic flocking glue and is composed of a mixed monomer, an emulsifier, an initiator, a cross-linking agent and water, and the mixed monomer comprises methyl methacrylate, dibutyl maleate, butyl acrylate, ethyl acrylate and epoxy resin. The electrostatic flocking glue is low in curing temperature, and is high in elongation and softness of glue film, and when the electrostatic flocking glue is applied to preparation of the thermoplastic electrostatic flocking fabric, a formed composite structure is stable, yield deformation can be improved, and the forming requirement is met after mechanical foaming; the electrostatic flocking fabric is stable in size at normal temperature, has the elastic elongation of 5-8%, can generate plastic deformation, which is uniform and free of tearing and cracking phenomena, at a thermal state (150-170 DEG C), and can be applied to a new material required by an embedded automobile carpet foot pad.

Description

technical field [0001] The invention belongs to the field of electrostatic flocking fabrics, in particular to a thermoplastic electrostatic flocking fabric and its preparation method and application. Background technique [0002] The main function of the car floor mat is to protect the original car carpet, and it must have the comprehensive performance of safety, health, comfort and beauty. Through continuous technical research and development and practical experience, people have concluded that the best choice for the floor mat material is the carpet material. However, due to the manufacturing process of carpet materials, they do not have the conditions for thermoplastic molding, so they can only be used for flat pads, and the protection area of ​​flat pads for the original car carpet is limited, thus causing many users to give up the best choice. In addition, carpet materials are not easy to take care of, which also brings bad experience to users. The biggest feature of e...
