Abstract

The invention relates to a protective clothing fabric and a preparation method thereof. The preparation method of the protective clothing fabric comprises the following steps of applying TiO2-SiO2-ZnO hybrid nano sol to a textile fabric through coating or padding, then drying the coated or padded textile fabric at 60-80 DEG C for 10-20 minutes, then drying at 80-100 DEG C for 20-30 minutes, and then boiling the treated textile fabric in distilled water for 60-90 minutes; and dissolving maleic anhydride and long-chain alkyl trimethoxy silane in absolute ethyl alcohol, uniformly stirring, soaking the prepared textile fabric in the prepared mixed solution for 60-90 minutes at room temperature, and finally, keeping the temperature at 100-120 DEG C for 30-60 minutes. The treated fabric does not contain carcinogenic halides and fluorides, has excellent self-cleaning performance, super-hydrophobicity and flame retardance, and does not influence the air permeability of the fabric.

Description

technical field [0001] The invention relates to a protective clothing fabric and a preparation method thereof. [0002] technical background [0003] With the development of science and technology and the progress of society, workers in more and more fields are required to wear protective clothing, such as fire protection, military industry, chemical industry, spray painting, laboratories, etc. At the same time, there are also multi-functional requirements for protective clothing fabrics. Usually, protective clothing fabrics should meet the requirements of waterproof, self-cleaning, flame retardant, heat insulation, and good air permeability. However, at present, my country's protective clothing is still mainly imported from foreign companies such as DuPont of the United States, Sperian of France, and North of the United States. The research and development and production of domestic protective clothing fabrics are still in the rising stage. [0004] The traditional method o...
