Abstract

The invention discloses a preparation method of flame-retardance and light-resistance phosphorylation fatliquor. Concentrated sulfuric acid and silver molybdate are added in castor oil, the temperature is increased to 70-85 DEG C, and the condensation backflow insulation reaction is performed for 3-4 hours to obtain a product A; phosphorus pentoxide dispersion liquid is added in the product A for evenly mixing, and the temperature is increased to 70-90 DEG C and kept for 3-4 hours to obtain a product B; a light resistant material is added in the product B for evenly mixing, the temperature is increased to 60-80 DEG C and kept for 1-3 hours, a flame retardant material and cuprous chloride are added in the product B, the temperature is increased to 70 DEG C, and the mixing reaction is performed for 2-3 hours to obtain a product D; and sodium hydroxide solution is dripped in the product D to become neutral to obtain brown liquid, and the brown liquid is the flame-retardance and light-resistance phosphorylation fatliquor. The prepared fatliquor not only retains the sensory performance and mechanical strength of traditional fatliquor, but also has excellent flame retardance and light resistance.

Description

technical field

[0001] The invention relates to a preparation method of a phosphorylated fatliquoring agent, in particular to a preparation method of a flame-retardant and light-resistant phosphorylated fatliquoring agent. Background technique

[0002] With the improvement of people's living standards, furniture leather and automotive leather are also increasing. At the same time, fires caused by leather and synthetic leather are also increasing. Therefore, the flame retardant problem of leather has become a research hotspot in the industry.

[0003] In the process of leather processing, fatliquoring is an essential process, which has a great influence on the sensory and mechanical properties of leather products. However, the fatliquor used for fatliquoring is easy to burn. Therefore, it is necessary to adjust the fatliquor Modification is carried out to reduce its flammability and improve its flame resistance, so as to meet the market demand for flame-retardant leather pr...
