Problems solved by technology

[0004] However, when two production lines are used in the prior art to prepare polyolefin bottom-back mosaic carpets, a layer of bonding material is scraped on the glue-coated blank non-woven fabric on the composite shaping production line, and then the glass fibers are bonded successively. The back of cloth and tiled carpets, among them, the glass fiber cloth and the surface of the non-woven fabric of the rubber-coated blanket tend to form bonding voids and weak bonds, resulting in poor dimensional stability of the tiled carpet. prone to dimensional changes

Abstract

The invention relates to the technical field of spliced carpets, in particular to a preparation method and device of a polyolefin bottom-back spliced carpet. The preparation method comprises the following steps: roller-coating a first allyl resin adhesive on the back surface of a tufted blank carpet to obtain a glued blank carpet; roller-coating a second layer of propenyl resin adhesive on the surface of the glass fiber cloth to obtain cloth adhesive glass fiber cloth; carrying out first rolling on the glued blank carpet and the glued surface of the glued glass fiber cloth to obtain a composite blank carpet; the glass fiber cloth surface of the composite blank carpet is coated with a third layer of propenyl resin bonding material in a blade coating mode, a bonding layer is formed, the cloth-glue composite blank carpet is obtained, and the propenyl resin bonding material comprises filler and propenyl resin glue; rolling a bottom back non-woven fabric layer on the surface of the bonding layer for the second time to obtain a semi-finished product; and cooling and shaping the semi-finished product to obtain the propylene-based back spliced carpet. The propylene-based back-spliced carpet obtained by the preparation method provided by the invention is high in dimensional stability, firm and durable.

Description

technical field [0001] The invention relates to the technical field of modular carpets, in particular to a preparation method and device for polyolefin backed modular carpets. Background technique [0002] At present, the preparation process of bonded patchwork carpets is generally a two-step method: first, the back of the embryonic carpet is pre-coated with VAE latex and dried to obtain a rubberized embryonic carpet through a pre-coating production line, and then the rubberized embryonic carpet and the bottom The backing material is bonded and then compounded and shaped through the composite shaping production line, wherein the bonding material includes asphalt. bonding material or acrylic resin bonding material. Wherein the cohesive block carpet prepared with asphalt bonding material is bitumen back mosaic carpet, and the cohesive block carpet prepared with acrylic resin bonding material is polyolefin back mosaic carpet. [0003] With the development of the economy and p...
