Development of New PP Fiber/Cannabis Composites

At present, the domestic production and processing of automotive interior panels mostly use yellow (red) hemp as the main raw material, using its good moisture absorption and desorption, corrosion, insulation, insulation, sound insulation, sound absorption, shock absorption and other characteristics, will pass through the needle felt Resin dipped, and finally molded at high temperature. However, the hemp/resin sheet metal processing equipment has a large investment and the production cost is high. The phenolic resin and its solvent used are volatile and flammable polymer compounds, and the pollution is serious. The production environment and safety are poor.
The PP fiber/hemp fiber composite material is made of a mixture of thermoplastic PP fiber and hemp short fiber, and the PP fiber is melted under the hot-pressing conditions to make the hemp fiber into a sheet, and through a special flame retardant treatment, the composite material has certain resistance. The burning effect can be widely applied to the automotive interior parts, bags, furniture and other production industries, and is an ideal alternative to the hemp/phenolic resin composites. From a technological and economical point of view, the new PP fiber/composite material has the following features: low energy consumption, no pollution, low raw material requirements, flame retardant, insulation, and advanced process technology.
