Problems solved by technology

[0004] Conventional flame retardants are mainly brominated flame retardants, brominated flame retardants have stable flame retardant properties and good compatibility with polymers, and occupy an important position in the application market of organic flame retardants, but brominated flame retardants Flame retardants are heavily dependent on bromine resources. In recent years, there has been a shortage of bromine resources. In addition, bromine flame retardants have appeared in the application process of flame retardant products. During the combustion process, a large amount of black smoke will be generated, which will affect people's escape in the event of a fire.
[0005] Halogen-free flame retardant intumescent flame retardant system generally consists of three parts: acid source (dehydrating agent), carbon source (char forming agent), and gas source (foaming agent). When the material is heated, the acid source releases inorganic Acid, inorganic acid and carbon source undergo esterification reaction, carbon source is dehydrated into charcoal, gas source can produce non-combustible gas, these gases are filled into the charcoal layer, and the molten charcoal layer expands and foams, and when the reaction is nearly completed, the system solidifies , forming a porous foam layer; the cracking of the acid source may also generate some free radicals, which play a role in gas phase quenching, promote the incomplete combustion of cracked substances, and further reduce the burning intensity

Abstract

The invention discloses a halogen-free flame-retardant ethylene composition and application thereof to artificial plants, the composition comprises an intumescent halogen-free flame retardant and a softening agent, and the intumescent halogen-free flame retardant is composed of a polyethylene carrier, a phosphorus flame retardant, a charring agent, an anti-dripping agent and a dispersing agent. When the halogen-free flame-retardant ethylene composition is applied to the artificial plants, the obtained artificial plants cannot release a large amount of toxic gas and black smoke in the combustion process, the combustion rate is low, and meanwhile, strong cancerogenic substances cannot be generated.

Description

technical field [0001] The invention relates to the technical field of simulated plants, in particular to a halogen-free flame-retardant vinyl composition and its application on simulated plants. Background technique [0002] In modern times, the artificial plant industry has developed rapidly, and artificial plants have become common items in people's lives. The simulated plants are mainly to embellish people's lives, create an idyllic atmosphere, and bring people the feeling of returning to nature. Especially in the public environment, such as hotel decoration, playgrounds, bars and other leisure consumption fields, the decoration of simulated plants gives people a feeling of being in nature. [0003] The material of the simulated plant is polyolefin material. The oxygen index of the polyolefin material is less than 22, which is a flammable substance. Once a fire accident occurs, the simulated plant will aggravate the spread of the fire. Therefore, it is necessary to deve...
