Abstract
The invention relates to the technical field of car carpets, in particular to a manufacturing method for a lightweight car front wall. The lightweight car front wall comprises hard felt and soft felt, and is characterized in that the hard felt and the soft felt are formed by bonding of an ethylene acrylic acid perforated film, the ethylene acrylic acid perforated film is Ethylene Acrylic Acid, and the thickness of the ethylene acrylic acid perforated film is 0.025mm, and ten hole positions are formed in one square centimeter of the ethylene acrylic acid perforated film. Compared with the prior art, the manufacturing method for the lightweight car front wall is provided, the ethylene acrylic acid perforated film replaces the traditional solvent based glue, so that the cohesiveness is improved, the acoustic performance is also improved, and the environmental protection is facilitated.
Description
Technical field
The present invention relates to car carpeting technical field, the manufacture method of specifically a kind of light-weighted car front wall.
Background technology
Traditional car front wall is the structure that hard felt and soft felt combine, and is to adopt solvent-borne type between felt and soft felt firmly
Glue is bondd, and using solvent-borne type glue, not only abnormal smells from the patient ratio is larger, is unfavorable for environmental protection, and using solvent-borne type glue corresponding zero
The sound insulation sound absorption qualities of part have very big loss.
Content of the invention
The present invention is to overcome the deficiencies in the prior art, provides a kind of manufacture method of light-weighted car front wall, by ethylene
Acrylic acid making hole film replaces traditional solvent-borne type glue, and caking property improves, and acoustical behavior also improves simultaneously, and is conducive to ring
Protect.
For achieving the above object, design a kind of light-weighted car front wall, include hard felt, soft felt it is characterised in that: firmly felt
And formed using ethylene acrylic making hole film bonding between soft felt, described ethylene acrylic making hole film is ethylene
Acrylic acid, and the thickness of ethylene acrylic making hole film is 0.025mm, and ethylene acrylic making hole film is 1 square centimeter
It is provided with 10 hole positions.
A kind of manufacture method of light-weighted car front wall, concrete manufacture method is as follows:
(1) hard felt, ethylene acrylic making hole film, soft felt are combined formation carpet surface；
(2) carpet surface is delivered in heater and is heated, temperature is 150 DEG C, heat time heating time is 40 seconds；
(3) carpet surface after heating is delivered in mould, is pressed, molding time is 100 seconds；
(4) carpet surface after will be compressing carries out Water Cutting technique by robot, and Water Cutting pressure is 25ksi.
The present invention compared with the existing technology, provides a kind of manufacture method of light-weighted car front wall, by ethylene acrylic
Making hole film replaces traditional solvent-borne type glue, and caking property improves, and acoustical behavior also improves simultaneously, and is conducive to environmental protection.
Hard felt, ethylene acrylic making hole film, after soft three layers of heating of felt, the fusing point of ethylene acrylic making hole film compares bottom, connects
Nearly 90 degrees Celsius, there is after thawing very strong caking property, then suppressed by outside frock, sandwich structure can be very firm,
Form one.Not only substantially reduce weight using the automobile front wall of soft, hard felt structure it is achieved that lightweight, its acoustical behavior and
Cost is also superior than the front wall of traditional re-coating layer.
Brief description
Fig. 1 is car front wall structural representation of the present invention.
Referring to Fig. 1,1 is hard felt, and 2 is ethylene acrylic making hole film, and 3 is soft felt.
Specific embodiment
Below according to accompanying drawing, the present invention is described further.
As shown in figure 1, hard formed using ethylene acrylic making hole film 2 bonding between felt 1 and soft felt 3, described ethylene propylene
Olefin(e) acid making hole film 2 is ethylene acrylic acid, and the thickness of ethylene acrylic making hole film 2 is 0.025mm, ethylene
Acrylic acid making hole film 2 is provided with 10 hole positions for 1 square centimeter.
A kind of manufacture method of light-weighted car front wall, concrete manufacture method is as follows:
(1) hard felt, ethylene acrylic making hole film, soft felt are combined formation carpet surface；
(2) carpet surface is delivered in heater and is heated, temperature is 150 DEG C, heat time heating time is 40 seconds；
(3) carpet surface after heating is delivered in mould, is pressed, molding time is 100 seconds；
(4) carpet surface after will be compressing carries out Water Cutting technique by robot, and Water Cutting pressure is 25ksi.
A kind of manufacture method of light-weighted car front wall is provided, ethylene acrylic making hole film is replaced traditional solvent-borne type
Glue, caking property improves, and acoustical behavior also improves simultaneously, and is conducive to environmental protection.
Hard felt, ethylene acrylic making hole film, after soft three layers of heating of felt, the fusing point of ethylene acrylic making hole film compares bottom, connects
Nearly 90 degrees Celsius, there is after thawing very strong caking property, then suppressed by outside frock, sandwich structure can be very firm,
Form one.Not only substantially reduce weight using the automobile front wall of soft, hard felt structure it is achieved that lightweight, its acoustical behavior and
Cost is also superior than the front wall of traditional re-coating layer.
Ethylene acrylic punching film thickness, in 0.025mm, is calculated by acoustical behavior parameter value it is stipulated that punch density is 1
Square centimeter 10 each hole position.
150 degree of front wall heating-up temperature, 40 seconds heat time heating times, molding time 100s.Water Cutting pressure 25ksi.
Using above-mentioned manufacture method, weight mitigates 50% than conventional carpet (recoating Rotating fields)；Sound insulation and sound absorption qualities ratio are used
Glue bonding soft or hard felt 15%；Can degrade recovery, environmental protection；Cost reduces by 25% than conventional carpet.
