Embodiment 1

[0034] Step 1: Prepare the Topping

[0035] a. Three openers respectively open polypropylene, polyester and spandex fibers. According to the use or process requirements of the surface layer, the composition ratio is set in the computer. After the work starts, the three openers open the polypropylene, polyester and spandex fibers according to the set ratio and send them into the air conveying pipeline.

[0036] b. After the polypropylene, polyester and spandex fibers enter the mixing box, they are evenly sprinkled on the working licker-in roller by the condenser. man air laying machine.

[0037] c. The air laying machine forms a fiber web with a certain thickness (weight) after the mixed fibers pass through the screen drum and the laying curtain.

[0038] d. The fibers formed into a net by the laying machine enter the needle loom, and the up and down reciprocating motion of the needle of the needle loom makes the fibers cohere, forming a felt with a certain strength and thic...

Abstract

The invention relates to an environment-friendly recyclable natural fiber automobile door plate which is formed by the steps of preparing a composite felt material by a core layer and a surface layer; and performing hot-press and forming. The natural fiber automobile door plate is characterized in that the core layer is prepared by mixing two kinds of natural fibers, namely a basalt fiber and fibrilia, and two kinds of chemical fibers, namely a polyster fiber and a polypropylene fiber, lapping and needling. The core layer comprises the following components in percentage by weight: 10 to 30 percent of basalt fiber, 10 to 30 percent of fibrilia, 20 to 30 percent of polyster fiber, and 30 to 40 percent of polypropylene fiber. The invention also provides a preparation process for the environment-friendly recyclable natural fiber automobile door plate. The environment-friendly recyclable natural fiber automobile door plate has the characteristics of low density, light mass, low cost, high intensity, high toughness, high safety, environmental-friendliness and the like, and can be deformed heavily and recycled.

Description

technical field [0001] The invention relates to an automobile door panel made by mixing natural fibers and chemical fibers and its preparation process. Background technique [0002] With the rapid development of the automobile industry and the rapid increase of automobile ownership, people have higher and higher requirements for the quality and environmental protection of automobile interior parts. The materials for automotive interior parts are developing in the direction of green environmental protection and recyclability. The composite substrates currently used for the production of automotive interior parts are usually polyurethane (PU) boards, polypropylene (PP) wood powder boards, glass steel plates, etc. Due to the defects of toxic chemical pollution, the original PU board and PP wood powder board can no longer meet the needs of modern automobile development, and are gradually being replaced by natural fiber composite materials. The processing of natural fiber compos...
