Description
Technical field
The invention belongs to a kind of productions of sound insulating pad under automobile interior decoration part processing technology more particularly to blanket car carpeting
Method.
Background technique
Automotive upholstery is generally mounted to play heat-insulated, sound insulation, beautiful and sound-absorbing etc. under automobile top, luggage case, floor
Effect.Increasingly pursue high-performance, environment-friendly type, energy-saving, lightweight, personalization epoch, the interior trim of automobile and automobile
Shape is the same, becomes the key factor that people choose automobile.Therefore the requirement to automotive upholstery is also higher and higher.Existing
Having in technology, the performance indicators such as the high sound-proofing of sound insulating pad, low grammes per square metre, VOC become the bottleneck of this kind of inside gadget development under carpet,
Restrict the development of carpet.Sound insulating pad majority is compressed individually molding using sheet material under existing carpet, and by foaming, water, which is cut, to be produced
Product, the disadvantage is that:
1. sound insulation value index does not reach requirement；
2. product weight is big, it is unfavorable for vehicle lightweight, energy conservation；
3. smell and VOC performance are poor.
Summary of the invention
The purpose of the present invention is to provide a kind of production methods of sound insulating pad under blanket car carpeting, to solve the prior art
Sound insulating pad has that soundproof effect difference and weight are big under middle car carpeting.
To achieve this purpose, the present invention adopts the following technical scheme:
A kind of production method of sound insulating pad under blanket car carpeting comprising following steps:
1) fiber filament is preheated in heating furnace, is sent to and carries out preforming on absorption mold, is then placed in steam
Molding die is formed, and blanket molding semi product is obtained, and the fiber filament raw material is PET fiber silk and low-melting fiber silk
Mixture, wherein the content of low-melting fiber silk (by weight) is 30~40%；
2) semi-finished product after molding are sent into the lower mold of die cutting die, and the upper mold of die cutting die pushes, upper mold with
Lower double of finished product of mold is punched out, and obtains punching semi-finished product；
3) punching semi-finished product are placed on the vertical jig of group, remove clout and label is pasted, obtains finished product.
Particularly, heating temperature of the fiber filament in heating furnace is 80 DEG C~100 DEG C in the step 1).
Particularly, the absorption mold in the step 1) is adsorbed using blower exhausting, the blower frequency 41Hz of blower
~49Hz.
Particularly, the mold temperature of steam molding mold is 160 DEG C~180 DEG C in the step 1), and steam is passed through the time
It is 4 seconds~6 seconds, evacuation time is 7 seconds~9 seconds.
Particularly, the pressure of the upper mold of die cutting die is controlled in 18Mbar~20Mbar, upper mold in the step 2)
It controls with the pressing molding time of lower mold at 30 seconds~40 seconds.
Particularly, the step 1) blanket is that fiber filament is directly preforming, and blanket is with a thickness of 5mm~50mm, unit area
Fiber filament dosage be 1618g/m2~1978g/m2。
Beneficial effects of the present invention are that the production method of sound insulating pad is simple under the blanket car carpeting compared with prior art
It is single effective, production efficiency is improved, not the accumulation problem of semi-finished product；And fiber filament is directly pre-formed as semi-finished product, it drops
The low purchase cost of raw material solves the problems, such as to be easy to appear after sheet material compression moulding to have loose bowels；So that blanket car carpeting
Lower sound insulating pad weight substantially reduces, and meets the light-weighted requirement of vehicle；And product sound insulation increases, smell and VOC table
Now preferably；The entire production process of product does not have harmful substance generation simultaneously, belongs to the moulding process of environmental protection.
