Embodiment Construction

[0013] A sofa fabric with good air permeability and wear resistance, which is composed of two layers. The base material is cloth, and the upper layer is a foamed PVC resin layer. The upper layer is made of the following raw materials in parts by weight (kg): SG-3 type PVC resin 40 , silicon carbide 2, polyvinyl alcohol 6, poly-1-butene 4, zinc oxide 2, wollastonite powder 10, methyltrimethoxysilane 2, didodecyl alcohol ester 7, stearic acid 2, protein powder 8. Isophthalic acid ester 4, azodicarbonamide 0.5, modified clay powder 3;

[0014] The preparation method of the sofa fabric with good air permeability and wear resistance is characterized in that it comprises the following steps:

[0015] A) Mix silicon carbide, polyvinyl alcohol, poly-1-butene, zinc oxide, wollastonite powder, methyltrimethoxysilane, didodecyl alcohol ester, and protein powder at 105-110°C at high speed Machine mixing for 8-12 minutes, then, cool down to 95-100°C, add the remaining ingredients, and sti...

Abstract

Provided are high-breathable and wearable sofa fabrics and a preparation method thereof. The sofa fabrics are characterized in that the sofa fabrics are formed by two layers in a composite mode, wherein the base material is cloth, the upper layer is a foaming PVC resin layer, and the upper layer is prepared by the following raw materials in parts by weight: 40 to 50 parts of SG-3 type PVC resin, 2 to 3 parts of silicon carbide, 6 to 8 parts of polyvinyl alcohol, 3 to 4 parts of poly-1-butene, 2 to 3 parts of zinc oxide, 5 to 10 parts of wollastonite powder, 2 to 3 parts of methyltrimethoxysilane, 5 to 7 parts of bis-dodecyl alcohol ester, 2 to 3 parts of stearic acid, 8 to 10 parts of protein powder, 3 to 4 parts of isophthalate, 0.3 to 0.5 parts of azodicarbonamide and 3 to 4 parts of modified clay powder. Through formula and technology improvements provided by the invention, the air permeability and flexibility of synthetic leather is enhanced; the fabric layers are subjected to foaming treatment so that the synthetic leather has natural and comfortable hand feel similar to that of natural leather; and the synthetic leather is not easily damaged or torn within 3 to 5 years, thereby being suitable to be used as the fabrics of a sofa.

Description
