Nanometer encapsulated halogen-free flame-retardant material and preparation method thereof

Abstract

The invention relates to a nanometer encapsulated halogen-free flame-retardant material. The nanometer encapsulated halogen-free flame-retardant material comprises renewable biological polyester silkchemical fiber fabric; two sides of the renewable biological polyester silk chemical fiber fabric are respectively coated with a nanometer encapsulated halogen-free flame-retardant coating A and a synergistic intumescent halogen-free flame-retardant coating B; and the outer side of the nanometer encapsulated halogen-free flame-retardant coating A is coated with a cationic ink-absorbing and color-developing coating C. The preparation method of the nanometer encapsulated halogen-free flame-retardant material comprises the steps of (1) weaving the renewable biological polyester silk chemical fiber fabric; (2) preparing the nanometer encapsulated halogen-free flame-retardant coating; (3) preparing the synergistic intumescent flame-retardant coating; (4) preparing the cationic ink-absorbing andcolor-developing coating; and (5) preparing the nanometer encapsulated halogen-free flame-retardant material. The nanometer encapsulated halogen-free flame-retardant material and the preparation method of the nanometer encapsulated halogen-free flame-retardant material disclosed by the invention have the following beneficial effects: (1) the printing color development effect is excellent, and thecolor development rate is 95% or more; (2) the weather resistance of the coating is excellent, and the weather resistance time can reach 2 years or more; (3) the flame retardant property is excellent; and (4) the biodegradability is excellent.

Description

technical field [0001] The invention belongs to the field of material science and engineering, and in particular relates to a nano-encapsulated halogen-free flame-retardant material and a preparation method thereof. Background technique [0002] With the development of modern cities, home decoration is becoming more and more luxurious, and it is filled with various decoration materials everywhere. Countless fires are caused by decorative materials every year. Among them, wallpaper and wall covering are one of the widely used materials, which has prompted people's desire for flame-retardant wallpaper and wall covering. [0003] Traditional flame retardant materials are formed by physically mixing halogen-containing flame retardants with coatings and then scraped. The flame retardant effect is excellent, but the mechanism of the flame retardant is to release halogens to dilute the oxygen content in the air to achieve For the purpose of fire extinguishing, the halogen release...

AI Technical Summary

Problems solved by technology

[0003] Traditional flame retardant materials are formed by physically mixing halogen-containing flame retardants with coatings and then scraped. The flame retardant effect is excellent, but the mechanism of the flame retardant is to release halogens to dilute the oxygen content in the air to achieve For the purpose of fire extinguishing, the halogen released contains strong irritation and corrosion, and more than 80% of fire casualties are caused by smoke, which makes halogen flame retardant products have great hidden dangers

Secondly, the base material used in these flame-retardant materials is ordinary chemical fiber cloth. Although it is biodegradable, the degradation rate is very slow, and some even take more than 5 years to completely degrade, which increases the burden on environmental governance.
