Abstract

The invention discloses a tanning agent with high flame-resistance amino-resin nano-composite function, which is prepared by the method as follows: firstly, melamine, dicyandiamide, formaldehyde and acidic components are used as raw material to prepare flame-resistance amino-resin prepolymer; secondly, montmorillonite or organic montmorillonite are modified by tetrakis hydroxymethyl phosphonium and silane coupling agents to obtain modified montmorillonite or modified organic montmorillonite; finally, the prepared flame-resistance amino-resin prepolymer and the obtained modified montmorillonite or the modified organic montmorillonite are processed through in-situ intercalation compounding reaction. The tanning agent not only has better tanning performance and retanning filling performance, but also brings good flame-resistance and washable migration resistance to leather goods, and the addition quantity is less, and the flame retardant efficiency is high.

Description

technical field

[0001] The invention belongs to the technical field of leather chemical materials, and in particular relates to a highly flame-retardant amino resin nanocomposite functional tanning agent for leather. Background technique

[0002] As a polymer material, leather is processed by chemical methods from raw hide preparation, tanning, fatliquoring, dyeing and finishing to finished leather, so each process requires certain Chemical materials, mainly including leather tanning agents, fatliquor, dyeing agents, finishing agents and other auxiliaries. Because these materials and leather will produce toxic fumes and corrosive gases when burned, it affects the application of leather in fields that require a certain degree of flame retardancy, such as protective clothing, sofas, furniture, upholstery, aircraft and automotive interiors and Cushion and other fields.

[0003] At present, the main way to make the leather have a certain flame retardancy is to add flame retard...
