One-press molding process for multilayer composite materials containing functional structures

By printing UV heat-resistant ink on kraft paper and using a press to heat and press, the fiber resin layer, functional layer and decorative layer are integrally thermo-pressed, solving the problems of poor pattern effect and easy peeling of decorative layer in the existing technology. This achieves multi-layer composite material with high bonding strength and good pattern effect, simplifies the process and reduces costs.

AI Technical Summary

Technical Problem

In the existing technology, the fiber resin layer, functional layer and decorative layer have problems such as poor visual effect of the pattern, lack of naturalness, complicated process, high cost, and the decorative layer is prone to falling off in high temperature environment.

Method used

UV heat-resistant ink is printed on kraft paper. The fiber resin layer, functional layer and decorative layer are integrally thermo-pressed by heating and pressing. The resin solution is used to penetrate the surface through the pores of the kraft paper to form an integral bond.

Benefits of technology

This technology has enabled the development of multilayer composite materials with high bonding strength, resistance to peeling, and good pattern effects, which simplifies the process and reduces production costs.

Abstract

The application discloses a one-time pressing forming process of a multilayer composite material containing a functional structure and relates to the technical field of plate processing processes.The one-time pressing forming process comprises the following steps: S1, preparing a decorative layer, a fiber resin layer and a functional layer, printing UV temperature-resistant ink on kraft paper to obtain the decorative layer, and immersing fiber cloth or fiber silk in a resin solution to obtain the fiber resin layer; S2, laminating and flattening the decorative layer, the fiber resin layer and the functional layer, the fiber resin layer is symmetrically arranged on the two sides of the functional layer, the decorative layer is arranged on the side of the fiber resin layer away from the functional layer, at least one fiber resin layer is arranged between the decorative layer and the functional layer, and a laminated body is obtained; and S3, placing the laminated body in a mold, using a press to perform warm and pressurized forming, and allowing the resin solution to infiltrate to the surface of the kraft paper through the pores of the kraft paper, so that the decorative layer, the fiber resin layer and the functional layer form an integral whole. The process has the advantages of high bonding strength, difficulty in peeling, good pattern effect and greatly reduced production cost.
