High temperature-resistant waterborne polyurethane leather soft clad fabric

Abstract

The invention belongs to the field of textile fabrics and particularly relates to a high temperature-resistant waterborne polyurethane leather soft clad fabric. The high temperature-resistant waterborne polyurethane leather soft clad fabric is prepared by the following components in parts by weight: 30-40 parts of ester ether copolymer polyol, 30-40 parts of polytetrahydrofuran ether glycol, 10-15parts of isocyanate, 3-5 parts of diol chain extender, 2.5 parts of microcrystalline wax, 0.5 part of an antioxidant BHT, 1.5 parts of bitter almond oil, 1.5 parts of a KH570 silane coupling agent, 0.5 part of tributyl citrate, 0.5 part of a light stabilizer, 3-4 parts of a salt-forming agent and 0.5-1 part of a SiO2 hybrid material. The high temperature-resistant waterborne polyurethane leathersoft clad fabric provided by the invention has the benefits that the formula is reasonable, and the cost is low; the prepared waterborne polyurethane leather soft clad fabric has good high temperatureresistance, and the performance cannot be affected during long-distance transportation and export; the high temperature-resistant waterborne polyurethane leather soft clad fabric is particularly suitable for summer high-temperature indoor installation.

Description

technical field [0001] The invention belongs to the field of textile fabrics, in particular to a high-temperature-resistant water-based polyurethane leather upholstery fabric. Background technique [0002] Soft pack refers to a wall decoration method that uses flexible materials to package the interior wall surface. The materials used are soft in texture and soft in color, which can soften the overall space atmosphere, and its deep three-dimensional sense can also enhance the quality of the home. In addition to beautifying the space, more importantly, it has functions such as sound absorption, sound insulation, moisture resistance, water resistance, oil resistance, dust resistance, dirt resistance, and collision resistance. In the past, soft bags were mostly used in high-end hotels, clubs, KTV and other places, and they were rare in homes. Now, commercial houses, villas and townhouses in some high-end communities will also be used in large areas when they are being renovat...

Problems solved by technology

[0003] The soft bag fabric produced by traditional technology has poor weather resistance. When it is low temperature in winter, it is prone to problems such as hardening, brittleness, peeling, peeling, and fracture. When it is high temperature in summer, it is prone to aging, corrosion, poor toughness, and low strength. problems, seriously affecting its service life and application fields
