Abstract

Nano slurry comprises, by weight, 10-50% of grafting-modified starch, 5-15% of acetic acid, and 1-5% of surface-modified Y-type molecular sieve; the surface-modified Y-type molecular sieve is prepared by: using phosphoric acid to wash a prepared Y-type molecular sieve, mixing a surface modifier with the Y-type molecular sieve, reacting at 30-50 DEG C for 3-10 h, cooling to room temperature, centrifugally separating, washing with double distilled water, and drying, wherein the mass ratio of the molecular sieve surface modifier with the Y-type molecular sieve is 0.05-0.1. The nano slurry, as composite slurry herein, has the advantages of good convenience of use, good slurry stability, significant nano-scale effect, easiness of sizing and desizing, good film smoothness and wear resistance, low cost, and environmental friendliness.

Description

technical field [0001] The invention relates to a preparation method of water-based nano-concentrated slurry, which belongs to the field of preparation of functional nano-materials. Background technique [0002] Textile size is an indispensable special polymer material in the textile production process. It is a key auxiliary to ensure the normal progress of textile production. Its performance directly affects the quality of textile products and production efficiency. For the textile industry, The amount of slurry is the second largest process raw material after fiber. [0003] The annual use of slurry in the world has reached more than 800,000 tons. The amount of size consumed for sizing abroad is more than 500,000 tons per year, of which starch size accounts for about 74%, PVA size is about 11%, polyacrylic acid (ester) size is about 12%, and other sizes Material accounts for about 3%. my country is a big textile country. In recent years, the annual size consumption has ...
