The bonding peel strength of car fabric, physical index such as elongation percentage etc..
Double-dot coating technique is that first on automobile fabric, coating materials point coating (can be the pulpous state that Thermoplastic hot melt's rubber powder does
Thing or the slurry of thermosetting resin), then uniformly sprinkle hot-melt adhesive powder, then again spot printing will be starched by pressure-vaccum powder
The unnecessary hot-melt adhesive powder of interlayer sops up, and only retains the hot-melt adhesive powder above point-like slurry point coating.Then by the vapour after double-dot coating
Slurry point coating and hot-melt adhesive powder are dried crosslinked fusing in point-like resin through drying room by car fabric, more multiple with by complex heating pressurization
The technique closed.The automobile fabric of double-dot coating technique need not before coating through high temperature (unlike powder point coating must be first by automobile
Fabric heats) and pressure (needing pressure to shift hot-melt adhesive powder group during powder point coating), therefore feel are very well, prime cement is typically multiple
Need not melt during conjunction it is only necessary to a small amount of hot-melt adhesive powder provides for sufficiently high bonding strength.And, by pressure-vaccum powder, even if
The electrostatic rubber powder occurring once in a while at coating position is rolled into a ball it is also possible to easily be sucked away, and is not likely to occur what big rubber powder group was formed
Pit quality problems.As pulp spot printing layer time point slurry uniformly, the form of slurry point is uniform in size, starches point coating point-type and coating uniform
The degree control ratio dusting uniformity controls easily a lot, is affected little by environmental factorss, and it doesn't matter with electrostatic and air flow, after
Although the continuous dusting uniformity also requires afterwards, rubber powder can roll on cloth cover after spreading and be bonded at a slurry point surface again, so coating
Amount and a slurry point uniformity, slurry dot density is relevant with slurry surface area, and the rubber powder not being stuck can be blotted by device for inhaling powdery substances only.
Therefore double-dot coating bonding effect is easier to control.And because being spot bonding, fiber between points and yarn do not have
Sticked by hot-melt adhesive powder, thus feel more soft fluffy, after being combined, the elongation percentage of product is higher, in follow-up curved surface lamination or note
When moulding, more preferably, percent defective is lower for appearance.Therefore, it be a kind of can be applied to automobile fabric be combined technical scheme.
