Description

Functionalized hyperbranched phosphorus-containing intumescent flame retardant, preparation method and flame-retardant polymer coating composition
Technical Field
The invention relates to the technical field of flame retardants, in particular to a functionalized hyperbranched phosphorus-containing intumescent flame retardant and a preparation method thereof; also relates to the application of the functional hyperbranched phosphorus-containing intumescent flame retardant in the flame-retardant polymer coating composition.
Background
The polymer material has the excellent characteristics of light weight, good chemical stability, easy processing and the like, and has become an important matrix material in the fields of aerospace, transportation, electricians and electronics, building materials and the like. However, most of high polymer materials belong to flammable materials, so that the high polymer materials provide convenience and increase great potential safety hazards.
The most effective flame retardant coating pastes currently used are still antimony bromide based systems. The bromine antimony type flame retardant system has excellent performance in gas phase flame retardant and high performance-price ratio, and is popular. Antimony, such as the most commonly used antimony oxide, is added into the brominated flame retardant to realize the synergistic effect of the antimony bromide, so that the flame retardant efficiency of the flame retardant system can be greatly improved, and the using amount of the flame retardant is reduced. Although halogen-based flame retardants have many excellent properties, high polymers containing the flame retardants release a large amount of smoke and toxic and corrosive gases (hydrogen halide gases) during combustion, and partially undergo thermal decomposition to form carcinogens of polyhalogenated dibenzodioxanes and polyhalogenated dibenzofurans. Various bromine-containing organic compounds are bioaccumulative, can affect the nervous system, the immune system and the reproductive system of organisms, and are global environmental pollutants.
The intumescent phosphorus-containing composite flame retardant system replaces bromine antimony type flame retardant and is a novel composite flame retardant which is widely concerned in the field of national flame retardance in recent years. The intumescent composite flame retardant adopts an acid source, a carbon source and a gas source to realize synergistic flame retardance, and is a classic synergistic combination in the field of flame retardance. The intumescent flame retardant system can realize high-efficiency char formation flame retardance through condensed phase flame retardance. A compact porous foam carbon layer is formed on the surface of the fabric, so that the further degradation of the inner high polymer and the release of combustible materials to the surface can be prevented, the transmission of a heat source to the high polymer can be prevented, and an oxygen source is isolated, so that the spread and the propagation of flame can be prevented.
With the attention of people on environmental protection, the requirements of intumescent flame retardants are more and more extensive, and the application scenes are also various. For example, intumescent flame retardants applied to engineering plastics require good water resistance. The intumescent flame retardant applied in the water-based flame-retardant coating needs to realize good dispersibility in water while keeping water resistance. At present, a halogen-free intumescent flame retardant which integrates the advantages of a bromine-antimony flame retardant system and an intumescent phosphorus-containing composite flame retardant system or partially integrates the advantages of the bromine-antimony flame retardant system and the intumescent phosphorus-containing composite flame retardant system and overcomes the disadvantages of the bromine-antimony flame retardant system and the intumescent phosphorus-containing composite flame retardant system is urgently needed in the market.
Meanwhile, the hyperbranched polymer has a dendritic, hyperbranched and 3D structure, the spatial structure is spherical, and the surface of the hyperbranched polymer can be constructed with a large number of different active functional groups. The special structure of the hyperbranched polymer endows the hyperbranched polymer with special properties, and the hyperbranched polymer has great application value in various fields such as coating, flame retardant, nanotechnology, biological materials, engineering plastics and the like.
