What are the three commonly used PP plastic flame retardants

What are the three commonly used PP plastic flame retardants

Flame retardant is the application of flame retardant technology in real life. It is a special chemical additive used to improve the combustion performance of combustible and flammable materials, and is widely used in the flame retardant processing of various decoration materials. After the flame retardant processing of the material, in the external fire attack, can effectively prevent, delay or terminate the spread of the flame, so as to achieve the role of flame retardant. 1. Most brominated flame retardants decompose at 200-300 ℃. This temperature range is also the decomposition temperature range of polypropylene. Therefore, when polypropylene is decomposed by heat, brominated flame retardants also begin to decompose and can capture its degradation.

How to classify environmentally friendly brominated flame retardants

How to classify environmentally friendly brominated flame retardants

Although halogen-free flame retardants such as phosphorus-nitrogen flame retardants and inorganic flame retardants are the hot spots in the research of plastic flame retardants, brominated flame retardants cannot be completely replaced because of their high flame retardant efficiency and wide application range. In order to reduce the pollution of the environment, the toxicity of the human body and the destruction of the ecology, many environmentally friendly brominated flame retardants have been developed, mainly polymeric brominated flame retardants and reactive brominated flame retardants. 1. Brominated epoxy resin: Brominated epoxy resin has excellent self-extinguishing and thermal stability, as well as good light stability, flame retardancy and high melt flow rate.

What is the role of asphalt flame retardant?

What is the role of asphalt flame retardant?

In recent decades, with the continuous progress of science and technology in China, asphalt as a basic construction raw material, its application technology and application fields are also in constant development. However, the flammability of asphalt itself makes it easy to be ignited at high temperatures, and combustion will be accompanied by a large amount of smoke and heat, which is extremely dangerous. Therefore, it is necessary to use asphalt flame retardants. So what is the role of asphalt flame retardant? Role one: endothermic asphalt flame retardant can occur under high temperature conditions a strong endothermic reaction, and absorb some of the heat released from combustion, thus reducing the temperature of the combustible surface, inhibiting the formation of flammable gases, and ultimately

What are the types of asphalt flame retardants on the market?

What are the types of asphalt flame retardants on the market?

1. The halogen flame retardant of asphalt flame retardant is mainly bromine flame retardant, which has good flame retardant effect, but it will release a large amount of toxic smoke in the flame retardant process, and decabromodiphenyl ether will also produce carcinogens in the combustion process, and the cost is high. 2. The nitrogen-phosphorus flame retardant of asphalt flame retardant generates strong dehydrating agent when heated at high temperature, which dehydrates and carbonizes the asphalt surface, isolates the external combustible gas and heat, and inhibits the combustion. At the same time, it decomposes to generate ammonia and water vapor when heated, and the oxygen concentration in the air is diluted by ammonia, which has a good flame retardant effect. In addition, good thermal stability, poor water solubility, low smoke, low toxicity, economical and practical, is a more ideal

Asphalt flame retardant: several advantages of flame retardant masterbatch

Asphalt flame retardant: several advantages of flame retardant masterbatch

Due to the advantages of flame retardant masterbatch (masterbatch) used in plastics in flame retardant efficiency, environmental protection, improvement of production efficiency, convenience and many other aspects, it has become an effective substitute for traditional flame retardants and has been widely used in plastic granulation, extrusion, injection molding and other aspects. According to the customer type, it can be divided into functional flame retardant masterbatch and functional flame retardant masterbatch. Functional flame retardant masterbatch is also called flame retardant masterbatch for modified plastic factory. The following advantages of using functional flame retardant masterbatch in modified plants 1. reduce costs. With the progress of science and technology, the continuous development of carrier plastics and equipment, high concentration, high dispersion and high compatibility become possible, and a small amount

The important role of fire retardant in home fire prevention

The important role of fire retardant in home fire prevention

Due to the flammability of decoration materials in the market, there is generally a lack of necessary standards, so owners should pay special attention to the purchase of decoration materials and try to choose inorganic decorative materials. Home decoration is the secondary processing of the inner surface of the wall, and ceiling materials are also easy to ignore their fire hazards. If the materials used are not flame retardant, once a fire occurs, the home decoration materials will be ignited first, so, home decoration fire prevention is very important. The construction procedure should be standardized. During the decoration of the 1., if the water and electricity installation project is ready and the gas pipeline is ready, try not to change it without authorization for convenience and beauty. If changes need to be made, or the original

Asphalt flame retardants: a mixture of three common flame retardants

Asphalt flame retardants: a mixture of three common flame retardants

Asphalt flame retardants: a mixture of three common flame retardants to obtain a synergistic effect of flame retardancy. Most flame retardants can play their role in a variety of courses, using hybrid systems. Mixed systems are often used in industry to achieve synergistic effects. Three Common Mixtures of Flame Retardant Manufacturers Flame Retardant 1, Compounds Containing Halogen and Phosphorus Phosphorus-containing Impedance Agent, which can be changed into phosphoric acid, metaphosphoric acid and polyphosphoric acid under the action of high temperature and oxidant. Play the role of dehydration and carbonization of oxygen-containing polymers, thus forming a coking protective layer on the surface and isolating oxygen and combustibles. This is a process of resistance. When mixed with halogen-containing compounds, it can

Research and Development Trend of Asphalt Flame Retardant

Research and Development Trend of Asphalt Flame Retardant

(1) Research direction of asphalt flame retardants: research on compatibility of flame retardants and asphalt; research and development of new nano-asphalt flame retardants and expandable graphite asphalt flame retardants; use flame retardant polymers, inorganic materials, etc. to modify asphalt, and develop environmentally friendly and stable asphalt flame retardants. (2) The research on the flame retardancy of asphalt mixture is relatively lacking, and the overall study of asphalt mixture is carried out to explore the possibility of each component of asphalt mixture on asphalt flame retardant and establish relevant evaluation methods.
