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 by a screw to a filter device, and the impurities in the raw material are filtered out through the filter device, and then the melt (melted out) is removed by a precise metering device. The raw material) is fed into the box, so that there is a stable pressure in the box to facilitate spinning, and then the filter device in the box will further filter out the impurities in the raw material, and the melt will be uniformly ejected from the spinneret through the box pressure. Then, the oil fume in the melt is extracted from the monomer, and then it goes through a cooling and suction device to make the wire thinner to meet all the requirements of the finished product. Inventory later.

[0023] The production technology of the present invention, on the basis of the above technology, has been improved, and the details are as follows:

Abstract

The invention discloses a production process of PE / PP composite material suitable for coating non-transferable glue, which is characterized in that it includes the following steps: (1) Antistatic and antiaging modification of PP raw materials to make PP modified (2) Use the PP modified masterbatch obtained in step (1) to make non-woven fabrics; (3) Pass the non-woven fabrics through a hot rolling mill; (4) Mix LDPE and LLDPE in a certain proportion, Then prepare the PE film mother liquor; (5) compound the PE film mother liquor prepared in step (4) on the non-woven fabric; (6) corona the composite film obtained in step (5) so that the surface tension of the film reaches Gluing requirements; (7) Rewind the composite film obtained in step (6) under tension control and cooling temperature control to control the flatness of the cloth surface. The invention solves the problem that the non-woven fabric cannot be glued and used, and the composite fastness of the film and the non-woven fabric has good tension on the surface of the film, so that the non-woven fabric can be fixed firmly, making it possible to replace the carpet.

Description

technical field [0001] The invention belongs to the field of manufacture of plastic products, and in particular relates to a production process of PE / PP composite material suitable for coating non-transfer adhesive. Background technique [0002] In order to create a festive atmosphere, people will lay red carpets on the ground on festive days such as weddings, meetings, festivals, etc. However, red carpets are used in large quantities, and it is difficult to recycle and store up space. People hope to find a better alternative to red carpets. carpet.
