Problems solved by technology

Chinese patent 20041004912.x discloses an environment-friendly thermoplastic natural palm hemp fiber composite base material for automotive interior parts, which solves the problem of non-environmental protection of the original PU board or PP wood powder board composite base material for automotive interior parts. Brown silk, hemp fiber and polypropylene fiber are mixed to make hemp felt as the middle substrate, which is made of composite with surface non-woven fabric and bottom PP film
However, this material has strong water absorption, and as the basic material of automotive interior parts, it is more likely to be damp and moldy
In addition, the surface layer is made of non-woven fabric for auxiliary stretching, and the bottom surface is made of PP film for bonding. The two sides are made of different materials. When the surface is bonded to the fabric, due to the uneven force on both sides, it is easy to deform, making Uneven interior surface

Embodiment 1

[0036] Step 1: Preparation of Needle-Punched Nonwovens

[0037] Get 49kg of polypropylene fibers, 12kg of Korean-made 4080 fibers and 39kg of polyester fibers and mix them evenly, and make needle-punched non-woven fabrics after carding and laying;

[0038] Step two:

[0039] Take 25kg of brown silk and hemp fiber, 30kg of polyester fiber and 40kg of polypropylene fiber, mix them evenly, then comb and lay the net, and then compound the needle-punched non-woven fabric prepared in the first step on one side, after acupuncture, make one side It is a semi-finished composite base material of needle-punched non-woven fabric and hemp fiber felt on one side;

[0040] third step:

[0041] Take two semi-finished products of the composite base material obtained in the second step, put one side of the hemp fiber felt together, heat and press, and mold once to form a middle layer of hemp fiber felt layer, and the surface layer and the bottom layer are needle-punched non-woven fabric layer...

Embodiment 2

[0043] The difference between this embodiment and Example 1 is that the material ratio is different, that is: in the first step, 40kg of polypropylene fiber, 15kg of Korean 4080 fiber and 45kg of polyester fiber; in the second step, 30kg of brown silk and hemp fiber, polyester fiber Fiber 35 kg and polypropylene fiber 40kg.

Embodiment 3

[0045] The difference between this embodiment and Example 1 is that the material ratio is different, that is: in the first step, 60 kg of polypropylene fiber, 10 kg of Korean 4080 fiber and 30 kg of polyester fiber; in the second step, 10 kg of brown silk and hemp fiber, 10 kg of polyester fiber, 40 kg of fiber and 50 kg of polypropylene fiber.

Abstract

The invention relates to a hamburg type fibrilia plate and a preparation method thereof, and belongs to the technical field of automobile decoration fittings. The hamburg type fibrilia plate is characterized in that: the hamburg type fibrilia plate comprises three layers of a surface layer (1), a fibrilia felt layer (2) and a bottom layer (3). The surface layer (1) and bottom layer (3) are both needle-punched non-woven fabrics layers. Components of the needle-punched non-woven fabrics comprise, by mass, 40-60% of polypropylene fiber, 8-20% of 4080 fiber and 30-50% of polyester fiber. Components of the fibrilia felt comprise, by mass, 10-30% of palm fiber and the fibrilia, 30-40% of the polyester fiber and 40-50% of the polypropylene fiber. The preparation method comprises: 1, preparing the needle-punched non-woven fabrics; 2, preparing a composite substrate half finished product, wherein one side of the composite substrate half finished product is the needle-punched non-woven fabrics,the other side of the composite substrate half finished product is the fibrilia felt; 3, carrying out one-time mould-pressing to prepare the finished product. The prepared hamburg type fibrilia platehas characteristics of high strength, good stretching resistance, collapsing and deformation resistance, good flatness, low probability of moisten and mildewing, no toxicity and environmental protection.

Description

technical field [0001] The invention relates to a Hamburg type hemp fiber board and a preparation method thereof, which is mainly used as a composite base material of automobile interior parts, and can also be used as a base material of furniture, building materials, packaging and the like. Background technique [0002] With the rapid development of the automotive industry, the quality requirements for automotive interior parts are also getting higher and higher. The quality of automotive interior parts depends critically on their composite substrates. In the past, the composite substrate of automotive interior parts used PU board or PP wood powder board. In its preparation and production process, benzene will be used, which is harmful to human body and does not meet the requirements of environmental protection. Chinese patent 20041004912.x discloses an environment-friendly thermoplastic natural palm hemp fiber composite base material for automotive interior parts, whi...
