Description
Technical field
The present invention relates to a kind of automotive trim panel, particularly relate to a kind of composite fibre automotive trim panel and production method thereof.
Background technology
Green, environmental protection, low-carbon (LC) have become the descriptor of automotive material development.Natural plant fibre have density low, than advantages such as performance height, inexpensive, aboundresources, degradables, natural-fiber composite material enjoys people to pay close attention in recent years.Carried out many research work both at home and abroad, some has a good application industrial.Yet the mechanical property of natural plant fibre is relatively poor relatively, use as strengthening the body material, improve also limited to resin-based performance, document (Composites Science and Technology, 2003,63:1287-1296) report adopts jute as strengthening body, PLA as matrix, adopts the method for hot pressing to prepare composite board, and hot strength has only improved one times nearly.
Chinese patent 201010142221.4 discloses a kind of acid fiber by polylactic and fibrilia automobile inner decoration member composite, its shortcoming is that compound felt needs to soak through slurries, adopt the hot pressing and the two one-step forming methods of colding pressing to make finished product, complex process, and the raising of the intensity of composite is little, is restricted in the higher application of mechanical property requirements.
On the other hand, the hear resistance of natural plant fibre is relatively poor, processing temperature can not be too high can not be too low, too highly surpass 250 ℃, flaxen fiber is burnt easily to be stuck with paste rottenly, and temperature is lower than 150 ℃ excessively, flaxen fiber is not easy to soften, and poor in processability makes that its selection to resin base material is more harsh.Chinese patent 200610168547.8 discloses the automotive trim panel that a kind of bamboo fibre/cotton fibriia/poly butylene succinate resin constitutes.Its shortcoming is that used biodegradable resin poly butylene succinate is still petroleum base and gets, and is not to come source biomass, and used fabric poly terephthalic acid ethylene glycol PET also derives from petroleum base, is not biodegradable.
Summary of the invention
The present invention aims to provide a kind of new green environment protection automotive trim panel and production method thereof.This automotive trim panel can carry out sufficient environmental protection treatment, particularly discarded object voluntarily degradation treatment fall, do not pollute the environment, comprise not increasing tellurian carbon dioxide, and technology is simple produces easily.When it is used as Auto door inner plating, ceiling base material, firm, the environmental protection of safety.
For reaching this purpose, the invention provides a kind of composite fibre automotive trim panel, comprise basic unit and non-woven or fabric face layer, its superficial layer is laminated at least one surface of described basic unit, wherein,
Basic unit is made up of following composite fibre:
First fiber: acid fiber by polylactic;
Second fiber: flaxen fiber is selected from least a of tossa, sisal fiber, ramee, flax fiber, hemp or kenaf;
The 3rd fiber: basalt fibre;
The percentage by weight of first fiber, second fiber, the 3rd fiber satisfies following equation: first fiber: second fiber: the 3rd fiber=20～70: 10～60: 10～60, and three kinds of total percentage by weights of fiber are 100%, and described superficial layer is made up of acid fiber by polylactic.
The invention provides a kind of method of producing above-mentioned composite fibre automotive trim panel, take following steps:
Felt 1 is made in (1) first fiber and the second fiber batch mixing lapping acupuncture,
(2) the 3rd fibers are made felt 2,
(3) felt 1 and felt 2 are by the alternating sequence shop and are laminated together, form the basic unit of the felted of predetermined thickness, and upper and lower two surfaces of this basic unit should be felt 1;
(4) described superficial layer is laminated at least one surface of described basic unit;
(5) described basic unit and superficial layer are carried out hot-forming, form the composite fiber plate of reservation shape.
The present invention adds the natural mineral fiber basalt fibre can remedy deficiency on the intensity.Basalt fibre derives from the natural basalt ore, has outstanding tensile property, and its hot strength is suitable with S type glass fibre, is higher than aramid fiber and general carbon fiber.It is good also to have high and low temperature resistance simultaneously, can continuous operation in-269 ℃～700 ℃ scopes; Acid-fast alkali-proof, anti-oxidant, radioresistance, anti-ultraviolet property is strong, hygroscopicity is low, adiabatic sound insulation, high temperature filtration is good, good wave penetrate capability, incompressible intensity and shear strength height, excellent fatigue durability is applicable to excellent properties such as multiple environment, is a kind of high-performance inorganic fibrous material of pure natural.Not only surpassed the employed E type of present manufacturing composite glass fibre on the basalt fiber performance comprehensively, and there is not the human body inadequacy by the basalt fibre reinforced composite materials, its goods can contact for a long time with human body, and this is that glass fibre reinforced composion is not available.In addition, the outstanding combination property advantage and the high ratio of performance to price of basalt fibre makes it have clear superiority in the competition of carbon fiber and aramid fiber, therefore, has good application prospects aspect the manufacturing novel high-performance automotive composite material.PLA be a kind of mainly be that corn is a raw material through the Biodegradable high molecular of chemical synthesis preparation with reproducible plant resources.Because PLA is the boiomacromolecule of raw material with the biomass resource, broken away from dependence to petroleum resources, carbon dioxide that degraded produces and water can return to the nature circle, kept nature " carbon cycle balance ".So the Application and Development of PLA can reduce the white pollution of polymeric scrap material to environment, save petroleum resources, suppress to increase the aggravation of the global greenhouse effect that causes owing to the clean discharge capacity of carbon dioxide, can satisfy the requirement of sustainable development.And the fusing point of PLA is easier to be compound hot-forming with flaxen fiber between 150 ℃～180 ℃.
The present invention is polymer adhesive with the acid fiber by polylactic, bonding flaxen fiber and basalt fibre, wherein flaxen fiber mainly plays the shock proof effect of energy-absorbing, basalt fibre is made skeleton enhancing body and is played humidification, like this preparation have the shock proof automotive trim panel of high strength, security is higher, all components after use all voluntarily degradation treatment fall, realize real environmental protection, zero carbon emission, and preparation technology's simple possible.
By the composite plate that acid fiber by polylactic, flaxen fiber and basalt fibre are formed, do not use the petrochemical industry material, so be complete environment-friendly material.And therefore the direct heat pressure adhesive of basic unit that superficial layer that acid fiber by polylactic is made and acid fiber by polylactic and flaxen fiber mixture are made and form sheet material does not need independent adhesive, and has simplified production technology and reduced production cost.In addition, the use of basalt fibre, can fully satisfy the rigidity requirement of bulk liner, and because acid fiber by polylactic is bonded in flaxen fiber and basalt fibre firmly, make these fibers from PLA, not peel off, so, the shape after bonding can well be kept, and can make the automotive trim panel of three-dimensional deep drawn.In addition, the automotive trim panel that makes does not use any harmful substance such as solvent, adhesive etc., so be eco-friendly.
Automotive trim panel can further be used and make roof of the vehicle, door inner panel etc.In this case, comprise 10～60% basalt fibres in the basic unit, can fully satisfy the rigidity requirement of bulk liner, thereby the safety that has guaranteed roof of the vehicle, door inner panel is firm.
