The invention belongs to the technical field of
textile, and particularly discloses a heat-resistant
phenol-yellowing-resistant agent as well as a preparation method and application thereof. The heat-resistant phenolic yellowing-resistant agent comprises the following
raw material components in parts by weight: 10-20 parts of
fatty acid dihydrazide, 5-10 parts of
fatty alcohol-
polyoxyethylene ether carboxylic acid, 2-5 parts of a surfactant and 65-83 parts of deionized water.
Fatty acid dihydrazide can capture free radicals and terminate an oxidation reaction chain, so that the fabric is protected from
oxidative damage, and thermal yellowing and phenolic yellowing are prevented; the molecular structure of
fatty alcohol-
polyoxyethylene ether carboxylic acid contains hydrophilic groups and hydrophobic groups at the same time, so that a layer of protective film can be accurately formed on the surface of the fabric, substances causing thermal yellowing and phenolic yellowing are effectively isolated, and oxidation of phenolic substances is inhibited.
Fatty acid dihydrazide is combined with
carboxylic acid groups of
fatty alcohol-
polyoxyethylene ether carboxylic acid through
hydrogen bonds or ionic bonds to form a compound, and thermal yellowing resistance, phenolic yellowing resistance, washability and stability of the fabric can be improved at the same time.
