Embodiment 1

[0057] (1) Preparation of silica modified sol

[0058]Add 50mL of absolute ethanol, 0.05mol of methyltrimethoxysilane, and 0.01mol of tetraethyl orthosilicate to the reactor successively, adjust the pH value to 9-10 with ammonia water, and raise the temperature to 50°C; Add 0.04 mol of water dropwise, and continue to stir for 2 hours after the drop of water is completed, so as to obtain a stable, uniform, and transparent silica sol.

[0059] (2) Preparation of phosphorus-silicon synergistic flame retardant

[0060] Add 10% ammonium polyphosphate to the sol prepared above, and stir at high speed for 2 hours until completely and evenly dispersed. Then put the mixture into a constant temperature drying oven at 50°C for 2 hours to make it gel and remove the solvent to obtain a phosphorus-silicon synergistic flame retardant.

Abstract

The invention discloses a method for solving the problems of moisture absorption and stickiness of a fabric with a phosphorus flame retardant coating. The method comprises the following steps: by taking two kinds of silane mixed monomers as modifiers and adopting ammonium hydrolysis in an alcohol medium, preparing silica modified sol, then adding 10-20% of phosphorus flame retardants and obtaining a phosphorus-silicon synergistic flame retardant by adopting sol-gel technology; finally coating a raised seat fabric with acrylate emulsion, the phosphorus-silicon synergistic flame retardant, a thickener and water and drying and baking the raised seat fabric, thus obtaining the product. The method has the beneficial effects that the flame retardant efficiency and water resistance of the fabric adopting the phosphorus-silicon synergistic flame retardant are improved, the combustion performance meets the requirement of the national B1 level, and meanwhile, the defects of surface efflorescence, soapy handfeel, stickiness, and the like of original phosphorus are improved.

Description

technical field [0001] The invention relates to the field of high-performance high-speed rail and motor car seat fabric preparation, in particular to a method for solving the problem of moisture absorption and stickiness of phosphorus-based flame-retardant coating fabrics. Background technique [0002] After nearly 10 years of rapid development, my country's high-speed rail and bullet trains have achieved world-renowned achievements, not only greatly improving the travel of 1.3 billion people, but also becoming the leading products for my country's export earnings. The development of high-speed trains is not only a process of continuously increasing speed, but also a process of continuously improving comfort and reliability to meet the needs of social and economic development. [0003] Interior textiles are one of the most critical materials in the development of motor vehicles and high-speed rail. Seat covers and other high-speed rail and motor car interior textiles not on...
