Flame-retardant antistatic polyester wall cloth and preparation process thereof

Abstract

The flame-retardant antistatic polyester wall cloth comprises a base cloth layer (1) and a surface cloth layer (3), a hot melt adhesive layer (2) is arranged between the base cloth layer (1) and the surface cloth layer (3), and a flame-retardant thermal insulation layer (4) is arranged on the surface of the surface cloth layer (3). The preparation process comprises the following steps: step A, carrying out impregnation alkali decrement process treatment on gray fabric of the polyester fabric to obtain a product A; step B, dyeing the product A to obtain a product B; step C, carrying out modified flame-retardant after-finishing on the surface of the product B by using a CS/MMT intumescent flame retardant in a layer-by-layer self-assembly manner to obtain a product C; and step D, bonding the product C with the base cloth layer through a hot melt adhesive to obtain a finished product. The method has the characteristics of easiness in production and capability of improving the product quality.

Description

technical field [0001] The invention relates to a preparation method of a polyester wall covering, in particular to a flame-retardant and antistatic polyester wall covering and a preparation process thereof. Background technique [0002] With the rapid development of the interior decoration industry, users have put forward new requirements for the interior wall decoration materials of the building. They believe that the wall covering should not only be beautiful in design, green and environmentally friendly, but also have special functions such as removing static electricity and preventing fire. At present, most of the wall coverings on the market are composed of a base fabric layer and a surface fabric layer bonded together, while polyester fiber is a chemical fiber. , is the preferred surface material for wall coverings. However, polyester has a low moisture regain and does not have good hygroscopicity. The electric charges generated by friction cannot be conducted and di...

Problems solved by technology

However, this phosphorus nitrogen flame retardant will reduce the breaking strength and dimensional stability of polyester fabrics, thereby reducing the inherent wrinkle resistance and durability of polyester fabrics

[0005] In the invention patent (antistatic sol-gel finishing solution and its application in the preparation of antistatic polyester), Chen Shuilin and others use reagents containing epoxy groups as raw materials, and use sol-gel method to prepare antistatic finishing solution to treat polyester fabrics. , although the finishing process is simple, the raw materials of organic reagents used in the synthesis of flame retardants are expensive and harmful to the environment, and the whole process takes a long time, which is not conducive to efficient production

[0006] The literature (Yuan Kai. Preparation and performance research of natural polymer/polyester fiber [D]. Shanghai: Donghua University, 2017.) describes that by controlling higher temperature and pressure, the surface of polyester fabric can be attached to sucrose fatty acid ester , and then based on the sol-gel method theory, chitosan and alginate were attached to the surface to form a thin fi
