Problems solved by technology

The improvement of tensile strength can generally be reinforced by the addition of inorganic fillers, but the misunderstanding of elongation at break is that both impact strength and elongation at break are the performance of toughness, so the difference between the two Modification means are interlinked
But in fact, the two are not equivalent concepts. The main means of improving impact strength, such as ACR, MBS and CPE, are not applicable to improving elongation at break.

Abstract

The invention relates to the technical field of wall coverings, in particular to a high-strength and high-toughness Teslin wall covering. The Teslin wall covering is woven from Teslin yarns. The Teslin yarns include a PVC skin layer and a polyester core layer. The PVC The skin layer is formed by melting and extruding modified PVC particles, and the modified PVC particles include PVC, epoxy soybean oil modified polyacrylate elastomer, inorganic fillers and auxiliary agents. Polyacrylate elastomer has the advantages of high strength, high toughness and good cold resistance. Using it as the toughening agent of PVC of the present invention can better improve the tensile strength, elongation at break and cold resistance of PVC, while the long chain After the epoxidized soybean oil participates in the cross-linked structure as the polyacrylate shell, the polyacrylate elastomer will improve in flexibility and have better compatibility with the PVC matrix, so it can also be Better improve the elongation at break of PVC.

Description

technical field [0001] The invention relates to the technical field of wall coverings, in particular to a high-strength and high-toughness Teslin wall covering. Background technique [0002] Teslin is a special textile produced by a shuttleless machine. It uses a composite yarn with a special covering structure, that is, a PVC / PET sheath-core yarn. The core is made of high-strength polyester industrial filament, and the cortex is made of anti-aging and anti-ultraviolet radiation PVC material. The polyester filament is stretched and wrapped, and after drawing and cooling, it forms a composite thread with a smooth surface, waterproof, oil-proof, non-toxic, and cool feeling. The warp yarns are made into weaving beams through intelligent warping machines, without sizing, and are directly woven into webs on the winding rapier looms, and then finished into final products. [0003] Although the mechanical properties of Teslin are mainly determined by the high-strength polyester c...
