Abstract
The invention relates to a manufacturing process for an automobile carpet with high sound-absorbing performance. The manufacturing process comprises the following steps: conveying a surface blanket of the carpet to a baking oven for heating at 210 to 220 DEG C for 45 to 50 s, wherein the surface blanket of the carpet comprises a surface PET layer, a fibrofelt layer, a middle PET layer and a back PET layer which are compounded together from top to bottom; conveying the heated surface blanket of the carpet to a molding machine and carrying out compression molding on the surface blanket between an upper mold and a lower mold of the molding machine, wherein the temperatures of the upper mold and the lower mold are both controlled to be 10 to 13 DEG C, mold clamping pressure is controlled to be 0.7 to 0.8 Mpa, molding time is controlled to be 40 to 50 s, and a semi-finished carpet product is obtained after completion of molding; and putting the semi-finished carpet product in a cooling shaping tool for secondary shaping, wherein the cooling shaping tool employs a cooling shaping manner and is free of temperature control, cooling shaping lasts for 30 to 40 s, and a finished carpet product is obtained after completion of secondary shaping. The manufacturing process has the advantages of simple steps, easiness in operation and no production of harmful gas in the whole manufacturing process and is an environment-friendly manufacturing process.
Description
Technical field
The present invention relates to a kind of manufacturing process of automotive upholstery, the present invention especially relates to a kind of manufacturing process of high sound-absorbing car carpeting.
Background technology
Traditional handicraft carpet is owing to considering that carpet is complex-shaped and without the load of high request, therefore having selected the materials such as plasticity fabulous PVC, EVA to be shaped as carpet.Shaping product advantage be the once-forming rear distortion of complex profile, shrink under, high with automobile ironware assembling degree.Because the competition of existing automobile market grows in intensity, marketing users to interior in the past only focus on outward appearance, moulding, sense of touch requirement be slowly upgraded to quiet comfortable requirement in car.Therefore the acoustic performance requirements of main engine plants to interior trim also grows with each passing day.And carpet stands in the breach as the inside gadget that automotive interior is maximum and also just requires the soonest to improve to the requirement of sound-absorbing.Traditional PVC, EVA carpet inhales the inside gadget requirement that sound insulation value difference can not meet main engine plants' centering high-performance vehicle.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of products obtained therefrom is lightweight, sound-absorbing good and the manufacturing process of wear-resisting high sound-absorbing car carpeting.
According to technical scheme provided by the invention, the manufacturing process of described a kind of high sound-absorbing car carpeting comprises the following steps:
A, carpet surface blanket is transported to baking oven heats, heating and temperature control is at 210 ~ 220 DEG C, heat time controlled at 40 ~ 50 seconds, and described carpet surface blanket comprises the top layer pet layer, fibre felt layer, middle pet layer and the back side PE layer that are combined with each other from top to bottom;
B, the carpet surface blanket that heating terminates is transported to forming machine upper die and lower die between compressing, the upper die and lower die temperature of forming machine all controls at 10 ~ 13 DEG C, and clamping pressure controls at 0.7 ~ 0.8Mpa, and molding time controls at 40 ~ 50 seconds, shaping end, obtains carpet semi-finished product;
C, carpet semi-finished product are put into cooling shaping fixture carry out secondary sizing, cooling shaping fixture temperature controls at 15 ~ 20 DEG C, and secondary shaping time controls at 30 ~ 40 seconds, and secondary sizing terminates, and obtains carpet finished product.
As preferably: the grammes per square metre of described top layer pet layer is 380 ~ 450g/ ㎡.The grammes per square metre of described fibre felt layer is 160 ~ 200g/ ㎡.The grammes per square metre of described middle pet layer is 350 ~ 400g/ ㎡.The grammes per square metre of described back side PE layer is 300 ~ 350g/ ㎡.
Manufacturing technology steps of the present invention is simple, be easy to operation, and whole manufacture process does not have pernicious gas to produce, and is environmentally friendly manufacturing process; The product that manufacturing process of the present invention obtains solves the problems such as traditional handicraft car carpeting sound-absorbing is poor, heavy, sound absorption qualities is poor, anti-wear performance is poor.
