Embodiment Construction

[0022] The process of making PP non-woven fabrics in the prior art is that the PP raw material is melted, stirred, and extruded to the filter device by the screw, and the impurities in the raw material are filtered through the filter device, and then the melt (melted off Raw material) into the box, so that there is a stable pressure in the box to facilitate spinning, and then the filter device in the box further filters out the impurities in the raw material, and the melt is evenly ejected from the spinneret through the box pressure. Then the oil fumes in the melt are removed from the monomer, and then the filaments are made finer through cooling and suction devices to meet all the requirements of the finished products. After laying, hot rolling, winding, cutting into finished size packaging After storage.

[0023] Production technology of the present invention, on the basis of above technology, has been improved, specifically as follows:

Abstract

The invention discloses a production process of a PE / PP composite suitable for coating of non-transfer adhesive, which is characterized by comprising the steps of (1) carrying out antistatic and anti-aging modification on a PP material to prepare PP modified master batch; (2) manufacturing a nonwoven fabric with the PP modified master batch obtained in the step (1); (3) hot-rolling the nonwoven fabric through a hot rolling mill; (4) mixing LDPE (low-density polyethylene) and LLDPE (linear low density polyethylene) according to a certain proportion, and then preparing a PE film mother liquor; (5) laminating the PE film mother liquor prepared in the step (4) to the nonwoven fabric; (6) applying corona to the composite film obtained in the step (5) to ensure that the surface tension of the film meets the gluing requirement; and (7) rolling the composite film obtained in the step (6) under tension control and cooling temperature control so as to control the cover flatness of the fabric. According to the invention, the problem that the nonwoven fabric cannot be glued for use is solved, the bonding firmness of the film and the nonwoven fabric is high, the tension of the surface of the film is good, the nonwoven fabric can be firmly fixed, and the nonwoven fabric to replace a carpet is made possible.
