The invention discloses a production process of an intelligent odorless automotive interior nanomaterial and belongs to the technical field of novel material
processing. The process comprises materialpreparation, blending, coarse opening, fine opening, large-bin cotton blending, quantitative cotton feeding,
carding, netting, pre-needling, primary needing, trimming and winding, unwinding of bottom-layer needled felt, roll type
powder scattering, electronic alignment and unwinding of upper-layer needled felt and 2-3 times of needling and composition to obtain composite needled felt, winding, unwinding of the composite needled felt,
far infrared preheating, blowing through heating, multi-roll cold rolling,
cutting, obtaining of a finished product, inspection and packaging. By means of the process, nano SiO2
powder is composited between two
layers of needled felt, the intelligent odorless automotive interior nanomaterial is obtained, the
aldehyde release amount reaches the
environmental protection standard, the
environmental protection grade reaches the grade E0, the
flavor is smaller than the grade 1, the sterilization and disinfection capability reaches 95% or above, the sound absorption coefficient is improved by 30%-40%,
noise is reduced by 10-15 db and the weight is reduced by 10%-20%.
