Description
Technical field
The utility model is related to composite material for vehicle field, and in particular to a kind of new high intensity, environmental protection it is recyclable, into
This sound absorption-type bus deck low, high.
Background technology
With developing rapidly for passenger traffic, people are increasingly paid close attention to car lightweight and riding comfort, government
13 planning in propose, automobile industry must pay attention to Green Development and energy-saving and emission-reduction, the lightweight of automotive material and can return
Receive to utilize and more and more paid close attention to by society.What accounting weight was maximum in bus interior is seat and floor.
, again to rigid foam sandwich composite from wood glue plate to bamboo slab rubber, its light-weighted distance is continuous for bus deck
Extend, but existing market be still mostly bamboo slab rubber, this floor unit area grammes per square metre is higher, and being unsatisfactory for lightweight needs
Ask；It is not recyclable, it is unsatisfactory for environmental requirement；Because using a large amount of glue, smell is big, and sound absorption qualities are poor, and riding comfort is not
It is good.
In order to meet the lightweight of chassis of bus material and recyclable, new type passenger car floor is also occurred in that in recent years, such as adopt
With PVC or aluminium honeycomb or polypropylene honeycomb interlayer structure.These structures effect in terms of loss of weight is very notable, but PVC
Material hydraulic performance decline at low temperature, there is the risk of brittle failure；Aluminium honeycomb and polypropylene honeycomb structure need to screw division when mounted
Position carries out specially treated, causes mounting process complicated, increases labor strength, and batch production is difficult.In addition, honeycomb floor is inhaled
Sound poor performance, thermal conductivity factor is high, and passenger's riding comfort is poor.
The A of patent CN 105667014 disclose a kind of bus deck, using the unidirectional continuous glass fibre enhancing thermoplastic of multilayer
Property resin prepreg piece and/or glass fabric strengthen thermoplastic resin preliminary-dip piece as top layer, with polypropylene, polyamide or heat
Plasticity polyester is matrix, lightweight visitor of the thermoplasticity light compound material board material using glass mat as reinforcement as core
Car floor, has the advantages that high intensity, shock resistance, recyclable, but it compared with bamboo slab rubber, composite floor board, cost is very high, pushes away
It is wide difficult.
Light GMT material is glass fiber reinforced polypropylene composite material (also known as LWRT, hereinafter referred to as), is by glass fibers
Peacekeeping polypropylene fibre uses Nonwoven Equipment, is processed by opening the operations such as bag, combing, lapping, acupuncture, hot pressing, has
The advantages of lightweight, sound-absorbing, recoverable.The LWRT material products of current continuous hot-press production are very wide in automotive vehicles applications
It is general, while bringing inevitable leftover bits problem.The recoverying and utilizing method species of leftover pieces is a lot, but most of adopts
It is after crushing, then is granulated by high temperature hot pressing or melting extrusion, is made pallet, building template, door-plate, decorative railing etc.；
The leftover pieces of crushing even directly can be processed into part by some automobile main frame maker by LFT-D techniques.But it is just domestic at present
For the producer of most of production LWRT materials, the recycling major way of leftover bits does pallet and building mould to be sold to outward
The manufacturer of plate, added value is very low, or even needs treatment of spending.
It is not enough for more than, LWRT leftover pieces are recycled the utility model proposes one kind, by multi-layer pressured system
Into high intensity, lightweight, recyclable new type passenger car floor.
