1results about How to "Reduce VOC value" patented technology

This invention relates to the field of automotive interior technology, specifically disclosing an environmentally friendly, high-strength automotive headliner. From bottom to top, it comprises: a non-woven fabric layer, a first adhesive layer cast on the surface of the non-woven fabric layer, a first toughening fiber felt bonded to the surface of the first adhesive layer, a second adhesive layer cast on the surface of the first toughening fiber felt, a polyurethane substrate bonded to the surface of the second adhesive layer, a third adhesive layer cast on the surface of the polyurethane substrate, a second toughening fiber felt bonded to the surface of the third adhesive layer, and a fourth adhesive layer cast on the surface of the second toughening fiber felt. Both the first and second toughening fiber felts are made of toughening fibers. The first, second, third, and fourth adhesive layers are all made of composite ethylene-vinyl acetate copolymer. The multi-layered structure of this automotive headliner features tight adhesion, preventing interlayer separation, good external rigidity, and no deformation. It also exhibits excellent sound absorption performance, is odorless, and is safe and environmentally friendly.
