Polyolefine water-proof tarpaulin and preparing method thereof

Abstract

The present invention relates to a polyolefine tarpaulin composition and preparing method thereof (thermo-plastic polyolefin based tarpaulin and preparing process thereof), wherein the tarpaulin for photographic printing of the present invention provides a reinforced structure with united strength in the outside of tarpaulin, which represents a superior processing property that a photographic print sheet maybe easily coupled to the outside of the tarpaulin. Due to the constitution of a singular number of the photographic print surface, the photographic print surface is clearly printed to discriminate, therefore the prime cost is reduced and work efficiency improved. At the same time, the polyolefine tarpaulin composition and preparing method thereof (thermo-plastic polyolefin based tarpaulin and preparing process thereof) prevents crack states due to the elastic force of the base material, which reinforces cold-proof, weather-ability, and abrasion resistance. Especially, it prevents the generation of a pollutant that is a problem in PVC tarpaulin of the related art by creating eco-friendly material and gives no harm to a human body, and enables 100 % recycling as recycling raw material for reducing the cost price after using.

Description

technical field [0001] The present invention relates to a polyolefin-based waterproof cloth and its manufacturing method (thermoplastic polyolefin-based waterproof cloth and its manufacturing method). [0002] Generally speaking, on the surface layer of tarpaulin, which is a fiber material base material, a digital printing surface such as an advertisement or content is directly printed by a digital printing machine, or a digital printing sheet for digital printing is bonded to a digital printing surface printed on the above-mentioned digital printing surface. For waterproof cloth, PVC waterproof cloth is usually used to print the digital printing surface, because the PVC material is inherently polar, so the digital printing surface is easier to be printed on the substrate during printing. Background technique [0003] But, if Figure 10 As shown, the tarpaulin (300) of the background art uses as a base material a tarpaulin in which fibers are impregnated with PVC or PE resin...

AI Technical Summary

Problems solved by technology

[0007] In particular, PVC tarpaulins cannot be recycled after use due to the emission of hazardous substances, namely environmental hormones. After they are discarded, they also cause environmental pollution due to the emission of hazardous substances, and the plasticizing effect of plasticizers leads to poor printing or reduced weather resistance. There are problems such as product discoloration
