Description

The production technology of car carpeting
Technical field
The present invention relates to a kind of production technology of car carpeting, specifically a kind of production is arranged on bottom automobile passenger compartment, plays sound-absorbing, sound insulation, beautifies and improve the production technology of the carpet of comfortableness effect, belong to technical field of automotive upholstery.
Background technology
Car carpeting is generally installed on bottom automobile passenger compartment, plays sound-absorbing, sound insulation, beautifies and improve comfortableness effect.More and more pursuing high-performance, environment-friendly type, energy-saving, lightweight, personalized epoch, the interior trim of automobile becomes the key factor that people choose automobile.Therefore also more and more higher to the requirement of automotive upholstery.In the prior art, the general production process of car carpeting have face blanket dry warm, compressing, high pressure waterjet, enclosure group vertical and inspection is cased.
There is following problem in existing product: 1, accessories of a product are many, and group is vertical, and to expend man-hour many; 2, a large amount of hot melt glue that uses pastes sound insulating pad, causes the poor performance such as the VOC of product, smell.The present invention adopts new production technology, preferably resolves the problems referred to above.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, provide a kind of meet product sound-absorbing, sound insulation, beautify and comfortableness prerequisite under, improve the performance such as product odour, VOC and the production technology of enhancing productivity.
The present invention namely by by sound insulating pad in advance lay enter in mold cavity, utilize the production technology of the bonding sound insulating pad of face blanket back finishing coat, process of producing product is made to substantially reduce the number the use amount of glue, save group and stand man-hour with artificial, improve production efficiency, belong to the manufacturing technique method of a kind of car carpeting of energy-conserving and environment-protective.
According to technical scheme provided by the invention, the production technology of car carpeting, step is as follows:
A, face blanket dry temperature: face blanket is put into double oven hanging type and dry temperature, upper Heating Zone Temperature is 200-240 DEG C, and lower Heating Zone Temperature is 300-340 DEG C, and drying the temperature time is 65-100s;
B, sound insulating pad are pre-buried: by sound insulating pad in advance lay enter in mold cavity;
C, compressing: step a is dried the face blanket after temperature and send in mould compressing together with the sound insulating pad of step b lay in advance, wherein face blanket is positioned at above sound insulating pad, obtains molding semi product; Molding time 45-65s during compacting, briquetting pressure is 85-100kgf/cm 2;
D, high pressure waterjet: on water-jet cutting machine, carry out high pressure waterjet by step c gained molding semi product; During cutting, cutting hydraulic pressure 40000 ~ 50000psi used, absorption air pressure: 0.6 ~ 0.8mpa; After having cut, remove the clout under cutting;
E, inspection: through after the assay was approved, vanning warehouse-in.
Face blanket described in step a is the composite surface blanket be made up of successively PET acupuncture face blanket layer, PE glued membrane or emulsion layer, the hard felt of PET and PE adhesive film; Or the composite surface blanket to be made up of successively PET acupuncture face blanket layer, EPDM or PE layer or EVA.Described in step a, the thickness of face blanket is 5-6mm.
Sound insulating pad described in step b is PET thermoplasticity felt or isopycnic one sound insulating pad.
Beneficial effect of the present invention: the present invention utilizes the mode that combines that sound insulating pad is pre-buried and face blanket back finishing coat baking temperature is softening, make when compression molding to carry out molding bonded between face blanket and sound insulating pad, but not at the scene with manual application's binding agent, not only can save artificial lift's production capacity, increase substantially production efficiency, and guarantee to manufacture the on-the-spot safety of environment and the health of operating personnel, improve the performance such as raising product odour, VOC of product simultaneously.
