Example Embodiment

[0035] Example 1:

[0036] Step 1: Preparation of Needle Punched Nonwovens

[0037] Take 49kg of polypropylene fiber, 12kg of 4080 fiber made in Korea and 39kg of polyester fiber and mix them evenly, after carding and laying, the needle-punched non-woven fabric is made;

[0038] Step 2:

[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, and after needle punching, make one side It is a semi-finished product of a composite base material with a needle-punched non-woven fabric and a 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 mat against each other, heat and pressurize, and mold the middle layer into a hemp fiber mat layer, and the surface layer and the...

Example Embodiment

[0042] Example 2:

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

Example Embodiment

[0044] Example 3:

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

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...
