Abstract

The invention relates to a production method of a car trunk carpet, which belongs to the technical field of car interiors. The production method mainly comprises the steps of selecting a PP hollow plate as a substrate of the trunk carpet, carrying out punching molding on a PET surface carpet, spraying an adhesive for bonding the PET surface carpet and the PP hollow plate, mounting accessories andcarrying out the inspection for forming a finished product. The production method solves the performance indexes of lightweight, small deformation and the like of the trunk carpet assembly, achieves the level 3 of the international leading level, greatly reduces the weight of the trunk carpet, and meets the requirements on the lightweight design of a whole car; a combined fixture adopted when spraying the adhesive and bonding in the procedure has the advantages of accurate positioning, convenient operation, realization of molding flow-line production and stable technology; the riveting way isadopted for mounting pad cotton with the complex shape, compared with the traditional hot-melt adhesive bonding way, the technology is simple and more environment-friendly; no semi-finished product isheaped during the process, thereby saving the manufacturing cost; and the whole production process of the product does not produce harmful substances, thereby belonging to environment-friendly products.

Description

technical field [0001] The invention relates to a production method of a car trunk carpet, specifically for being installed in the car trunk to play the role of practicality (can put things) and beauty, and belongs to the technical field of car interior parts. Background technique [0002] Automotive interior parts are generally installed on the top of the car, the trunk, and the cab to play the role of heat insulation, sound insulation, aesthetics and practicality. In the era of more and more pursuit of high performance, environmental protection, energy saving, lightweight, and individualization, the interior of a car, like the shape of a car, has become an important factor for people to choose a car. Therefore, the requirements for automotive interior parts are getting higher and higher. In the prior art, performance indicators such as low weight and high strength of coat racks become bottlenecks, restricting the development of luggage carpets. Existing trunk carpet majo...
