On the one hand, trunk panels meet customer and national regulations regarding odor, VOC and other hazardous volatile content. Therefore, in the process of processing and forming the plate for the back box and installing accessories, the using amount of adhesives such as hot melt glue, solvent glue, water-based glue and the like is required to be reduced. On the other hand, the automotive product needs to avoid sharp edge effect, prevent hand from being cut and scratch the hand piece.
The main forming modes of the board for the honeycomb board trunk reinforced by the PP/glass fiber surface layer at present are as follows:
the first is formed by adopting a mould pressing edge sealing mode: firstly heating and softening a honeycomb board substrate, then transferring the softened substrate into a lower die of a double-layer die, immediately laying a carpet surface on the front surface of the honeycomb board, finally closing an upper die of the die, and directly chopping the honeycomb board into a shape required by a product by using a knife edge of the die. The molding mode has the advantages that the front fabric is directly bonded by the heated and softened PP without additional adhesives such as glue, the introduction of the adhesives such as the glue is avoided, and the product has the advantages of good smell and VOC. But by adopting the processing mode, the cutting trace of the edge of the product after the cutting die is cut is obvious, a large amount of glass fibers are exposed, the edge after cutting is sharp, the risk of scratching a user is caused in the using process, and meanwhile, the hand piece can be scratched.
The second is that the molding scheme is not adopted, and the molding is carried out in a mode of brushing glue and edge covering: firstly, cutting the honeycomb board substrate according to the appearance of the product, and bonding the front fabric with the honeycomb board substrate by spraying adhesives such as glue. The front fabric is larger than the substrate in size, and redundant parts can be reversely wrapped on the back of the product, so that the edge of the product is well protected. The forming mode has the advantages that the problem of edge cutting marks caused by the first processing mode can be avoided, the edge effect is good, and a user and an opponent cannot be scratched. However, the processing mode has the defects that the odor and VOC of the product exceed standards due to the use of a large amount of glue or adhesive, and the requirements of customers cannot be met.
