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 and carrying 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 is adopted 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 is heaped 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.

Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of production technology of making baggage compartment carpet of the PP hollow sheeting, this product weight is light, not yielding, certain thickness is arranged again, can satisfy the requirement of automobile to the appearance and modeling of baggage compartment carpet, this product whole process of production does not have objectionable impurities to produce, and belongs to the production method of the car trunk carpet of environment-friendly products.
The production craft step of car trunk carpet of the present invention is as follows:
The production method of car trunk carpet is characterized in that, said method comprising the steps of:
(1) the face blanket is die-cut: PET (polyethylene terephthalate) face blanket is carried out die-cutly on cutting machine according to designing requirement, the severing time is 0.32 ± 0.02s, and build up time is 1s;
(2) the spray sticker closes: with die-cut good PET face blanket and PP (polypropylene) hollow sheeting (originating firm: utilize make-up machine compression moulding behind the spray glue Wuxi Just Want Precision Packing Co., Ltd.), form composite panel; During compacting, molding time: 10 ± 1s, forming pressure: 5 ± 1MPa; Used adhesion agent is during spray glue: the pressure sensitive hot melten gel; The amount of used adhesion agent is: 110～130g/m
2
(3) fill up cotton riveted: utilize the rivet machine welding at described composite panel middle part and edge, weld time 2 ± 1s PET pad cotton;
(4) annex is installed: the stay cord band is packed into from the position, hole that is arranged on the described PP hollow sheeting, the stay cord connector is lived from the Kong Weiyu stay cord bracelet that is arranged at described blanket surface again;
(5) check: through after the assay was approved, the vanning warehouse-in.
When the face blanket is die-cut, if the face blanket not during severing, strengthens the severing time, control duration scope:＜0.01s.
The present invention selects plane cord velvebeen lining for use.
Compared with the prior art the present invention has the following advantages:
The invention solves the baggage compartment carpet lightweight, be difficult for performance figure such as shrinkage distortion, reached international forward position level; Greatly reduce the weight of baggage compartment carpet, satisfied the requirement of car load light-weight design; Material adopts the PP hollow sheeting, makes product not yielding, adopts the moulding Detroit automation, process stabilizing; The rigidity height of product can not fracture, ftracture; Saved manufacturing cost; The product whole process of production does not have objectionable impurities to produce, and belongs to environment-friendly products.
