Embodiment 1

[0017] Embodiment 1: to produce 1600g / m 2 Taking natural hemp composite fiberboard as an example, the specific gravity of each layer is 200g / m2 for the rubber surface layer 2 , middle base layer 1220g / m 2 , fabric layer 180g / m 2 . The proportion of fibers used in each layer is:

[0018] Rubber surface layer: 50% polypropylene fiber, 50% polyethylene fiber.

[0019] Middle base layer: 37% jute fiber, 10% polyester fiber, 53% polypropylene fiber.

[0020] Fabric layer: 30% polypropylene fiber, 70% polyester fiber.

[0021] The polyester fiber used in the fabric layer is black polyester fiber, with a specification of 1.5 to 2 denier (denier: the weight of a fiber with a length of 9 km at a given moisture regain), and the polyester fiber used in other layers is white polyester fiber, with a specification of 1.5 to 2 denier , The length of polyester fiber is 51-65 mm; the specification of polypropylene fiber is 5-6 denier, and the fiber length is 74-78 mm; hemp fiber is cut i...

Embodiment 2

[0027] Embodiment 2: the ratio of each layer of fiber is:

[0028] Rubber surface layer: 70% polypropylene fiber, 30% polyethylene fiber.

[0029] Intermediate base: 45% jute fiber, 20% polyester fiber, 35% polypropylene fiber.

[0030] Fabric layer: 50% polypropylene fiber, 50% polyester fiber.

[0031] Processing method is with embodiment 1. The performance of the obtained board: the thickness of the board is 3.5 mm, the bending strength is 9.97 MPa, the tensile strength is 9.33 MPa, and the elongation at break is 12.31%.

Embodiment 3

[0032] Embodiment 3: the ratio of each layer of fiber is:

[0033] Rubber surface layer: 90% polypropylene fiber, 10% polyethylene fiber.

[0034] Middle base layer: jute fiber 41%, polyester fiber 14%, polypropylene fiber 45%.

[0035] Fabric layer: 40% polypropylene fiber, 60% polyester fiber.

[0036] Processing method is with embodiment 1. The performance of the obtained board: the thickness of the board is 3.5 mm, the bending strength is 7.83 MPa, the tensile strength is 7.66 MPa, and the elongation at break is 13.53%.

Abstract

A composite bast fiber board for the internal decoration of car is composed of adhesive layer, sandwich substrate layer and surface layer, and is prepared through sequentially spreading said three layers, needling to become a composite bast felt, and hot pressing. Said sandwich substrate is made of the mixture of bast fibers (37-45%), polyester fibers (10-20%) and polypropylene fibers (35-53%).

Description

Technical field [0001] The invention relates to a composite board made of natural plant fibers and chemical fibers and mainly used for automotive interior parts. Background technique [0002] With the improvement of people's requirements for environmental protection, the materials of automotive interior parts are developing in the direction of "green" environmental protection materials. Some materials used in the production of automotive interior parts in the early stage, such as PU board (polyurethane board), glass steel and other materials, due to The deficiencies in pollution are gradually being replaced by natural hemp fiber composite materials. The processing of natural hemp fiber composites usually involves mixing natural fibers and chemical fibers into felt boards and then heating and pressing them. Such as the patent document of CN1605462A discloses such a kind of environment-friendly thermoplastic natural brown hemp fiber automotive interior trim composite substrat...
