Description
Technical field
The present invention relates to a kind of method that passage sound insulating pad in automobile is prepared using composite, specifically use EPDM
Re-coating layer composite thermoplastic PET felt, as the main material structure method of preparing passage sound insulating pad in automobile of product, belongs to vapour
Car exterior trimming parts technical field.
Background technology
Access sites during passage sound insulating pad is mounted in below automotive floor panel panel beating in automobile, exhaustor and power transmission shaft in
Between pass through, this part primarily serves the heat intercepting exhaustor and distributing, intercepts the noise producing when exhaustor and power transmission shaft work
Effect to passenger compartment conduction.
Now widely used middle passage sound insulation cushion material is mainly thermosetting waste woven felt and is combined EPDM re-coating layer, its shortcoming
It is：1st, thermosetting waste woven felt adopts epoxy resin to mix, and can discharge a large amount of toxic and harmfuls in high-temperature molding, can be to one
Line production operation personnel health work the mischief safely；2nd, in order to process harmful gass, factory needs the newly-increased process absorbing gas
Equipment, thus increase production cost put into；3rd, thermosetting waste woven felt needs first to carry out EPDM weight of fitting again after mould is compressing
Coating, production process is many, complex process, causes production cost to raise.
Content of the invention
The purpose of the present invention is to overcome above-mentioned weak point, provides a kind of asepsis environment-protecting, with low cost, production technology simple
The method that passage sound insulating pad in automobile is prepared using composite that is single, meeting car load acoustical demands.The heat adopting in the present invention
Plasticity PET felt does not produce toxic and harmful during baking of heating softens, and will not produce impact to Health Status For Workers Exposed,
Without the special toxic harmful exhaust gas processing equipment of input；And PET felt can be combined into one in advance with EPDM re-coating layer
Structure is supplied, and reduces production link, reduces production cost.
The technical scheme providing according to the present invention, a kind of method that passage sound insulating pad in automobile is prepared using composite,
Step is：
（1）The base material of EPDM composite thermoplastic PET felt dries temperature：Composite base material is put into feeding baking oven on automatic baking Wembledon tennis open competition chain add
Temperature, makes the low-melting fiber in PET felt melt；Substrate surface temperature is 280-320 DEG C, dries warm time 80-100s；
（2）The lay of base material：Step（1）Dry the composite base material after temperature finishes and positioning in mould be will be delivered to by network chain；
（3）Compressing：Step（2）Fabric starts press after the completion of laying and pushes Guan Bi mould, sets die pressure as 170-
190Bar, pressing forming time is about 35-55s, compressing after get product middle passage sound insulating pad；
（4）Recheck：To step（3）In gained, passage sound insulating pad finished product, after quality examination, sticks qualified label and is packaged into, that is,
Can.
Described composite base material is from top to bottom followed successively by：PET non-woven fabrics, EPDM re-coating layer, thermoplasticity PET felt and PET nonwoven
Cloth.
In described composite base material, PET non-woven fabrics density is 100-120g/m2；EPDM re-coating layer density is 2000-4000g/
m2；Thermoplasticity PET felt density is 1400-1600g/m2；PET non-woven fabrics density is 100-120g/m2.
Described thermoplasticity PET felt is PET+low-melting point PET（I.e. L-PET）, fiber mixed structure, mixed proportion presses weight
Measuring percentages is：PET 50-60%, L-PET fiber 40-50%.
The preparation process of composite base material is as follows：
Top layer PET non-woven fabrics are combined with EPDM re-coating layer：EPDM is made it soften with viscosity by baking oven for heating, sets
Temperature is 180 ± 10 DEG C；By running roller, top layer PET non-woven fabrics are rolled with the EPDM softening and be combined with each other, make semi-finished product
1；
Thermoplasticity PET carpet veneer is non-woven fabric compounded with bottom PET：Uniformly spray PE rubber powder on the composite surface of PET non-woven fabrics,
Grammes per square metre is set as 40-60g/m2；Non-woven fabrics and PET felt are together sent into by baking oven for heating by pipeline, design temperature is 150 ±
10 DEG C, so that nonwoven surface rubber powder is melted and be bonded together with PET felt, finally by running roller, composite felt is flattened, make half
Finished product 2；
Uniformly spray PE rubber powder in the EPDM exposure of semi-finished product 1 again, grammes per square metre is set as 40-60g/m2, by pipeline
Send into baking oven for heating after semi-finished product 1 and semi-finished product 2 are laminated, design temperature is 150 ± 10 DEG C, so that semi-finished product 1 and semi-finished product 2 is glued
Composite felt together, is flattened finally by running roller, makes composite base material finished product by knot.
Step（3）Described in mold periphery profile design be edge of a knife form, directly by edge contour when product is compressing
And assembling hole position punching molding realization.
Beneficial effects of the present invention：The thermoplasticity PET felt that the present invention adopts does not produce during baking of heating softens
Toxic and harmful, will not produce impact to Health Status For Workers Exposed, without the special toxic harmful exhaust gas processing equipment of input；
And PET felt and EPDM re-coating layer can be combined into one the structure supply of material in advance, reduce production link, reduce production cost.
