| description | The invention provides a composite material with soft touch and a preparation method thereof, which belongs to the technical field of polymer material modification. The composite material is preparedfrom the following raw materials: polypropylene resin, modified straw powder, a toughening agent, a lubricating agent, glass fibers, polyethylene and a compatilizer. The modification method of the modified straw powder comprises the following steps: soaking the straw powder in a strong alkali solution, then washing to be neutral, drying, then adding a coupling agent and polyethylene wax, and treating for 20-40 minutes under the condition that the temperature is 70-90 DEG C. The preparation method comprises the following steps: adding a mixture of the polypropylene resin, the toughening agent,the lubricating agent and the polyethylene from a main feeding port of an extruder, adding a mixture of the modified straw powder and the glass fiber from a side feeding port of the extruder, and thencarrying out melt extrusio |
