Abstract

The invention discloses an automobile interior decorative part made of fibrilia-enhanced foams and a manufacturing method thereof. A surface leather layer, a 10%-40% of flax felt and polyurethane foams are compounded to form the interior decorative part. The surface leather layer is laid in a forming die. The flax felt of 5-20 mm in thickness and formed through carding and lapping one or more mixed fibrilia selected from natural jute, bastose and flax is laid onto the surface leather layer. After that, high-pressure mixed polyurethane materials are uniformly and quantitatively cast onto the flax felt for die assembly. The temperature of the die is kept at a certain value for foaming and curing. After the die is opened, excess materials are trimmed and removed. Finally, the automobile interior decorative part is formed after the perforating process.

Description

A kind of flaxen fiber enhanced foaming automotive upholstery and manufacture method thereof
Technical field
The present invention relates to automotive trim and manufacture field, be specifically related to a kind of flaxen fiber enhanced foaming automotive upholstery And manufacture method, it is used for manufacturing the interior products such as fascia, inner decorative ceiling.
Background technology
China is automobile making big country, automobile making yield the first in the world, along with development and the ring of auto industry Improving constantly of guaranteed request, automotive trim product lightweight, environmental friendliness, comfortable, attractive in appearance has become development Trend.Flaxen fiber is natural fiber, is natural reproducible resource, abundance, cheap, utilizes fiber crops Fiber is prepared as the inside gadget such as fascia, ceiling, product as strengthening organic filler with polyurethane foam Density is low, has preferable intensity, good heat-insulating sound-insulating effect, has the good feature of environmental protection and economy.
At present foaming enhancing material is glass fibre, be characterized in than great, cannot degrade, it is impossible to adapt to Current automobile industry environmental protection, light-weighted requirement.Fascia described in patent CN201510174494.X It is formed by the instrument board of acid ether cast filled glass fiber, polyethers and isocyanates described in CN02109038.6 The glass fiber reinforced polyurethane skeleton etc. of the glass fibre molding in above-mentioned mould is injected in mixing.
Flaxen fiber substitutes traditional glass fibre as strengthening organic filler, not only alleviates weight, solves again The environmental problem that glass fibre cannot be degraded.Flaxen fiber reinforcing material application master in automotive trim at present Polypropylene hybrid guided mode to be concentrated on bears down on one the products such as paulin, compound as described by patent CN200610039121.2 Fiber crops felt, CN200910116808.5 described in tossa and polypropylene fiber thorn eedle thorn numb felt, Polymer base linen fiber described in CN201210588373.6 strengthens composite etc., is thermoplasticity flaxen fiber multiple Condensation material needs the most heated rear compression molding.This kind of product density is the biggest, and sound-insulating and heat-insulating weak effect, The baroque products such as such as instrument board cannot be manufactured.
Summary of the invention
For not enough present in existing foaming automobile interior trim technology, the invention provides a kind of lightweight, environmental protection, Be prone to molding, flaxen fiber enhanced foaming automotive trim that combination property is strong.
The present invention also provides for the manufacture method of a kind of flaxen fiber enhanced foaming automotive upholstery.
In order to solve the problems referred to above, present invention employs following concrete technical scheme:
A kind of flaxen fiber enhanced foaming automotive upholstery, by top leather, 10%-40% natural ramie fiber carded web Paving forms fiber crops felt and is composited with polyurethane foam.
A kind of manufacture method of flaxen fiber enhanced foaming automotive upholstery, step is as follows:
(1) the flaxen fiber carded web of one or more mixing in natural Corchorus olitorius L., ambary, Caulis et Folium Lini is paved into 5-20mm The numb felt of thickness；
(2) top leather is laid in mould die；
(3) taking net laying thick for 5-20mm becomes fiber crops felt to be laid on leather after pruning by die size；
(4) account for, by fiber crops felt, the polyurethane material that quantitative high-pressure mixes by weight ratio 10%-40% and be uniformly cast in fiber crops On felt, then matched moulds；
(5) mold temperature is controlled at 40-50 DEG C, foamed solidification die sinking after 5-7 minute, take out foaming piece；
(6) repair and cut away unnecessary rim charge and i.e. make required interior products.
Compared to the prior art, its remarkable advantage is the present invention:
(1) using natural ramie fiber (fiber crops felt), as packing material, flaxen fiber is renewable, degradable, environmental protection；
(2) mechanical property and density can be taken into account: the present invention can adjust fiber crops felt according to different types of gadget product With the weight when product density of polyurethane, meet product mechanical property requirements, reduce product weight；
(3) present invention can be used for manufacturing the interior products such as fascia, ceiling, can be applicable to labyrinth Product one step foaming molding.
Only should be appreciated that all combinations of aforementioned concepts and the extra design described in greater detail below One of subject matter of the disclosure is can be viewed as in the case of such design is the most conflicting Point.It addition, all combinations of theme required for protection are considered as a part for the subject matter of the disclosure.
The foregoing and other side that present invention teach that can be more fully appreciated with from the following description in conjunction with accompanying drawing Face, embodiment and feature.The feature of other additional aspect such as illustrative embodiments of the present invention and/or have Benefit effect will be the most obvious, or by the practice according to the detailed description of the invention that present invention teach that In learn.
Accompanying drawing explanation
Accompanying drawing is not intended to drawn to scale.In the accompanying drawings, each identical or approximation phase illustrated in each figure Same ingredient can be indicated by the same numeral.For clarity, in each figure, the most each Ingredient is the most labeled.Now, by by example and various aspects of the invention are described in reference to the drawings Embodiment, wherein:
Fig. 1 is the manufacturing process flow diagram of flaxen fiber enhanced foaming automotive upholstery.
Detailed description of the invention
In order to know more about the technology contents of the present invention, especially exemplified by specific embodiment and coordinate institute's accompanying drawings to be described as follows.
Each side the most with reference to the accompanying drawings to describe the present invention, the reality illustrated shown in the drawings of many Execute example.Embodiment of the disclosure and must not be intended to include all aspects of the invention.Should be appreciated that Jie above The multiple design continued and embodiment, and those designs and the embodiment that describe in more detail below are permissible In in many ways, any one is implemented, this is because design disclosed in this invention and embodiment do not limit In any embodiment.It addition, aspects more disclosed by the invention can be used alone, or and the present invention Disclosed otherwise any appropriately combined use.
