Description
Technical Field
The invention relates to the technical field of wall cloth, in particular to high-strength high-toughness textilene wall cloth.
Background
Teslin is a special textile produced by a shuttleless loom, and adopts composite yarns with a special cladding structure, namely PVC/PET sheath-core yarns. The core body is made of high-strength polyester industrial filament, and the skin layer is made of polyvinyl chloride PVC material with ageing resistance and ultraviolet radiation resistance. Stretching and covering the polyester filament yarn, and drawing and cooling to form the composite yarn with smooth surface, water resistance, oil resistance, no toxicity and cool feeling. Warp yarns are made into a driving shaft through an intelligent warping machine, sizing is not needed, the warp yarns are directly woven on a winding rapier loom to form a net, and then the net is finished into a final product.
Although the mechanical properties of the textilene are mainly determined by the high-strength polyester core yarn, the mechanical properties occur in the skin layer at the stress point, so that the mechanical properties are equally important as the tensile properties of the PVC skin layer. The tensile properties are mainly reflected by tensile strength and elongation at break, which are generally in an inverse correlation relationship, i.e., high tensile strength generally results in low elongation at break. The improvement in tensile strength can be generally reinforced by the addition of an inorganic filler, but the error zone that tends to be easily generated with respect to elongation at break is: the impact strength and the elongation at break are both the expression of toughness, so the modification means of the two are communicated. However, they are not equivalent concepts, and the main means for improving the impact strength, such as ACR, MBS, CPE, etc., are not suitable for improving the elongation at break.

This comparative example differs from example 1 in that:
the toughening agent is an ACR toughening agent, the ACR toughening agent is P-551A of Mitsubishi, and the plasticizer is dimethyl terephthalate dioctyl ester.
The PVC of example 1 and of comparative examples 1 to 4 were prepared as test specimens and tested for the properties of elongation at break in terms of tensile strength according to GB/T10402006, the results of which are given in the following table:
| tensile Strength (MPa) | Elongation at Break (%) | |

Compared with the conventional ACR toughening agent, the epoxy soybean oil modified polyurethane disclosed by the invention has the advantage that the mechanical property of PVC is remarkably improved compared with that of the conventional ACR toughening agent. As can be seen from the comparison of example 1 and comparative example 2, dioctyl terephthalate is generally more suitable as a primary plasticizer than epoxidized soybean oil, but comparative example 3 does not achieve the best performance because dioctyl terephthalate does not modify the compatibility of the epoxidized soybean oil-modified polyurethane as well as epoxidized soybean oil; it can be seen from the comparison of comparative examples 1-3 that when the conventional toughening agent is used, the application of dioctyl terephthalate can have a higher improvement effect than the epoxidized soybean oil, and it is also proved that the mechanical property of the invention is improved not only by the independent effect of the plasticizer or the toughening agent, but also by the combination of the plasticizer and the toughening agent, the compatibility is improved, and thus, the mechanical property performance is better.
The above-described embodiments are preferred implementations of the present invention, and the present invention may be implemented in other ways without departing from the spirit of the present invention.
