Problems solved by technology

[0010] It is not difficult to see from the above method for fire protection of upholstered furniture that it has the following defects: 1. The fireproof interlayer or fireproof sheath needs to be composed of multi-layer structures, so the process for producing fireproof upholstered furniture is complicated, the process is long and high production cost
2. The introduction

Abstract

The invention discloses artificial fireproof PVC leather for a cushion furniture, wherein the artificial fireproof PVC leather is prepared by compositing a surface rubber layer containing a fireproof additive and a cloth base subjected to fireproof processing. A sofa assembled by the artificial fireproof PVC leather and a fireproof core material is tested according to combustibility test standards of interior decoration material seats in BS5852 in the United Kingdom, and results show that the sofa accords with requirements of the standards. The invention also discloses a preparation method ofthe artificial fireproof PVC leather. The artificial fireproof PVC leather provided in the invention can be directly coated on the inner buffer material, so the cushion furniture has an excellent long-term fireproof performance, the structure of the cushion furniture is simplified, the flexibility and the elasticity required by the fireproof cushion furniture are not influenced, and a process flow for producing the fireproof cushion furniture is similar to a process flow for producing a common cushion furniture, thereby the production cost is reduced, the large scale production can be easily formed, and the popularization and the application are easy.

Description

technical field [0001] The invention belongs to the technical field of fireproof PVC artificial leather for upholstered furniture and its preparation, and in particular relates to a fireproof PVC artificial leather for upholstered furniture and a preparation method thereof. Test standard, with excellent fire performance. Background technique [0002] Upholstered furniture refers to a type of soft furniture that is equipped with cushioning materials (such as springs, foam, cotton wool, etc.) inside and covered with finishing materials (such as textiles, velvet, leather, etc.) , pillows, ottomans, sleeping bags, quilts, cushions, cushions and similar parts sold in conjunction with furniture. Generally speaking, the internal cushioning materials of upholstered furniture—foam, cotton wool, and the external covering and veneer artificial leather are all flammable substances, which can easily cause fires under open or dark fire sources, causing serious loss of property and life. ...
