Problems solved by technology

Although phosphorus pentoxide and phosphorus trichloride are not poisonous products, they are dangerous goods, and there are unsafe factors in their transportation and use
The products made by the reaction of amine compounds with formaldehyde and phosphorus pentoxide still have unreacted formaldehyde that pollutes the environment, while the reaction of phosphorus trichloride with acetic acid or acetic anhydride requires corrosion resistance and airtightness of equipment are very high
At the same time, this kind of products will also cause "eutrophication" of the water area after the printing and dyeing wastewater is discharged and flows into rivers and lakes, causing excessive algae reproduction, reducing the oxygen content in the water, and suffocating aquatic animals to death, resulting in an ecological imbalance of aquatic organisms.
In addition, this kind of chelating dispersant also has poor alkali resistance, and cannot be used for deboiling and bleaching one-bath one-step method under high alkali conditions, etc.

Abstract

The invention relates to a polyamide polyamide high-efficiency chelate disperse stabilizer and relative production. Wherein, said stabilizer is formed by macromolecule polymer, alkyl poly-glycoside hydrolysate, and water, while their components are 60-95, 5-10, and 0-30; the chelate Ca=800mg / g. The molecule weight of said invention is 500-2000. And its production can avoid dangerous chemicals, with better degradation, strong chelate ability.

Description

1. Field of invention [0001] The invention relates to a chelating dispersion stabilizer and its preparation method and application, more particularly to a phosphorus-free alkali-resistant high-efficiency chelation dispersion stabilizer and its preparation method and application. 2. Background technology [0002] With the rapid development of science and technology, environmental pollution has increasingly threatened the ecological balance and the living environment of human beings. This serious problem has attracted widespread attention from all over the world, and measures have been taken to formulate corresponding laws and regulations. In order to prevent further deterioration of the ecology. For textiles, various countries have successively issued textile eco-labels and environmental regulations, such as: Oeko-Tex100, ISO14000 series standards, etc. In the impact of textiles on the environment, textile printing and dyeing auxiliaries have far more impact on the ecology t...
