Abstract

The invention belongs to the technical field of algal polysaccharide materials, and particularly relates to a preparation method of an ultralow-smoke algal polysaccharide material, which comprises thefollowing steps: preparing nano silver chloride sol by using marine biological resource sodium alginate as a raw material through a particle size controllable technique, shaping by using forming equipment, and carrying out ion exchange reaction in a coagulating bath of divalent metal ions to obtain the ultralow-smoke algal polysaccharide material. The method is simple in process, high in operability, free of pollution, environmentally friendly in material and suitable for large-batch industrial production.

Description

technical field

[0001] The invention belongs to the technical field of seaweed polysaccharide materials, in particular to a preparation method of ultra-low-smoke seaweed polysaccharide materials. Background technique

[0002] In addition to shopping malls, hotels, restaurants, entertainment venues, vehicles and other crowded places that are prone to fire, residential buildings in urban and rural areas are also prone to fire. In these numerous fires, the smoke produced by combustible materials, including flame-retardant materials, is very harmful. People who were "burned to death" were actually poisoned by smoke, suffocated, and then burned to death. So smoke is the main cause of casualties. Therefore, in addition to having a good flame-retardant effect, it is more important to achieve low-smoke or smoke-free flame-retardant materials.

[0003] In the prior art, halogenated flame retardants are one of the good flame retardants, but halogenated flame retardants usually incr...
