Description

Method of manufacturing pre-impregnated thermoplastic resin structures

technical field

The invention relates to a method for manufacturing a continuous reinforced fiber cloth structure pre-impregnated with thermoplastic resin, especially the continuous reinforced fiber that can be perfectly combined with the complex structure required by the design through secondary injection molding in the mold by using thermoplastic resin Laminated structure molded product.

Background technique

With the global issue of "energy saving and carbon reduction" and the rapid development of mobile information technology products, the industry has begun to pursue materials that are more impact-resistant, anti-electromagnetic, and can be recycled and reused to reduce the amount of petrochemical resins. In order to meet global standards Environmental protection requirements and the needs of related industries.

At present, the continuous reinforced fiber laminates used in the casings of IT products in the composite industry are mostly pre-impregnated with thermosetting resins (such as epoxy resins). Fiber or engineering plastic reinforced fiber generally has continuous fibers, which are pre-impregnated with thermosetting resin, so that the surface of the fiber is impregnated with thermosetting resin, and the pre-impregnated thermosetting resin is manually placed into the mold for molding, and then heated by an appropriate mechanical device. After pressing into a fixed shape or laminating the fibers in the mold, heat the thermosetting resin to mature. The cured thermosetting plastic can be tightly bonded to the surface of the fiber, and the interface between the thermosetting plastic and the fiber can be used to absorb external impact energy. , thus forming a structure with high impact resistance.

The characteristic of thermosetting plastics is that once the flowable thermosetting resin is heated and cured into a solid thermosetting plastic, the thermosetting plastic will not be deformed by subsequent heating, that is, it will still maintain its original solid shape.

In the prior art, when the fiber accumulation layer is heated and pressurized in the mold, the prepreg resin will be crystallized and hardened due to pressure, temperature or time difference, causing a part of the resin amount between the fibers to be insufficient to cover all the fiber surfaces or Filling the gaps between the fibers makes the surface of the molded product concave, which not only causes a lack of appearance, but also affects the structural strength. In order to improve the above-mentioned defects, the concave parts of the molded products need to be filled with soil, painted and polished to meet the appearance requirements, but it is time-consuming and labor-intensive. The dust caused by polishing and polishing is also likely to cause pollution, which requires a lot of labor costs but is difficult to mass-produce. Production.

In addition, most of the existing technologies use thermosetting epoxy resin as the pre-impregnated resin, which requires a very long man-hour to complete the curing process of crystallization, cooling to hardening and molding, which consumes a lot of power and energy. , when combined with any material, it is necessary to apply an interface solvent resin to improve the bonding force, thus causing additional manufacturing costs and production defect rates in subsequent applications.

What's more, with the high awareness of environmental protection, thermosetting resins cannot be recycled and reused, which is always a doubt and obstacle, especially when the impregnated resin of epoxy resin is discarded, it can only be crushed and buried or mixed into ready-mixed soil for research. , can not be burned, because of the toxic gas produced during the combustion process.

Therefore, there is a need for a method of manufacturing a pre-impregnated thermoplastic resin structure to produce a reinforced fiber laminate structure with thermoplastic pre-impregnated resin, so that when components of different materials need to be combined, the thermoplastic resin can be regelled by heating. It is achieved without coating the interface solvent resin to improve the bonding force. At the same time, the thermoplastic prepreg resin is viscous during the molding process and will not be partially cured when heated, thereby avoiding the appearance of the product from sagging and improving the protection. effect and aesthetics.
