Method for preparing nanometer negative ion automobile inner decoration facing

Abstract

The invention discloses a method for preparing a post-finished nanometer negative ion automobile internal decorative fabric, comprising the following steps that: nanometer negative ion powder is added into the de-ionized water and is stirred at a high speed; a dispersing agent of sodium polyacrylate and a silicone hydride coupling agent are added at a temperature of between 40 and 50 DEG C; the mass ratio of the de-ionized water to the nanometer negative ion powder to the dispersing agent and to the coupling agent is 100:8 to 15:3.0 to 3.5:3 to 4, the silicone hydride coupling agent is selected from vinyl silane, amino silane, meth acryloxy silane, hydrosulphonyl silane or uramido silane; the nanometer negative ion finishing agent is obtained by stirring and the ultra audible sound dispersing process; after the nanometer negative ion finishing agent is diluted, and the immersing-padding-drying technique is adopted to prepare the post-finished nanometer negative ion automobile internal decorative fabric. The nanometer negative ion plug material not only has good shakeproof stability and rub resistance, but also releases air negative ions with high concentration, thereby being suitable for the automobile internal decoration field.

Description

technical field [0001] The invention relates to a fabric treatment method, in particular to a finishing method for automobile interior fabrics, wherein the finished automobile interior fabrics are nano anion fabrics. Background technique [0002] In recent years, with the continuous improvement of my country's automobile production and grades, and the intensification of market competition, automobiles are required to have a comfortable, healthy, and environmentally friendly cabin environment decoration. The interior decoration materials of new cars contain toxic gases, mainly including benzene, formaldehyde, and acetone. , xylene, etc., will cause headaches, fatigue and other poisoning symptoms; harmful substances such as carbon monoxide, gasoline odor, amines, nicotine, bacteria and other harmful substances produced by automobile engines and air-conditioning evaporators will reduce the air quality in the compartment. Therefore, domestic automobile manufacturers have also acc...

Problems solved by technology

[0004] Yet existing anion textiles are not suitable for direct application as automotive interior fabrics, and this is because it has the following disadvantages: 1. the binding fastness of the anion powder particles on the existing anion textiles to the fabric is not high, when the long-term operation of the automobile is in Under bumpy and frictional conditions, negative ion particles are likely to vibrate and fall, which seriously affects its function of generating negative air ions and has a short service life; The concentration of negative ions is not high, it is difficult to maintain a high concentration of negative ions in a limited volume of air environment, and cannot fully exert the unique health care effect
