Abstract

The invention belongs to the field of skin collagen treatment, and provides flame-retardant nano fat-liquoring complex agent, particularly flame-retardant polymer/montmorillonite nano fat-liquoring complex agent. The functional fat-liquoring agent prevails in the market development, and the fat-liquoring agents having the properties of filling and water-resisting are invented one after another inrecent years, however, few research reports concerning the flame-retardant fat-liquoring agent are published, whereas sofa leather, automobile cushion leather and other leather require higher flame-retardant performance. The flame-retardant polymer/montmorillonite nano fat-liquoring complex agent of the invention is prepared through the following steps: performing the partial amidation reaction between low-cost rapeseed oil and diethylamine; then, performing the reaction with acrylic acid to prepare polymer modified fat-liquoring agent; and further subjecting the polymer modified fat-liquoring agent and the nano material montmorillonite to processing methods, such as mechanical stirring and ultrasonic treatment. The fat-liquoring agent can be used alone or combined with other anionic, cationic and non-ionic fat-liquoring agent. The fat-liquored crust leather is soft, the grain surface is full, and the fat-liquored crust leather has higher flame-retardant performance.

Description

technical field [0001] The invention belongs to the field of skin collagen treatment, and specifically relates to a preparation method of a flame-retardant polymer / montmorillonite nanocomposite fatliquoring agent. technical background [0002] Fatliquor is one of the most used leather chemicals in tanning production, and it has an extremely important impact on the performance of the finished leather. It can penetrate into the collagen fibers of the skin to lubricate and plasticize, making the molecular chain segments easy to move, and the finished leather is soft, waterproof, sun-proof, moist and elastic. Functional fatliquor has become the trend of market development. In recent years, fatliquor with filling and waterproof properties have come out one after another, but there are few research reports on fatliquor with flame retardancy, while sofa leather, There is an increasing demand for flame retardancy in automotive cushion leather and the like.
