Zinc borate flame retardant for polyolefin
In seven hydrated zinc sulfate, borax, anhydrous Zinc Oxide as the raw material, the synthetic polyolefin borax method in water bath heating environment using zinc borate FB (4zno? 6b2o3? 7H2O), affected by multi factor orthogonal method to study the charge ratio, the ratio of liquid to solid, heating time, heating temperature of four kinds of factors on the flame retardant properties of products the optimum condition is determined.
The experimental results show that the controlled reaction temperature is 90 degrees, the ratio of zinc sulfate to borax batching material is 1.10:1, the liquid solid mass ratio is 6.5:1, and the reaction time is 5.5h. Under these conditions, the zinc borate flame retardant synthesized by the polyolefin is the best.
In recent years, the economic loss caused by the fire has been shocking, and it has aroused the widespread concern of the world. In order to change the flammability of various daily industrial products, it is necessary to consider the use and addition of high quality polyolefin zinc borate flame retardant.
The flame retardant can be roughly divided into organic flame retardants and inorganic flame retardants. Among these two kinds of flame retardants, inorganic flame retardants are becoming the mainstream of flame retardants industry because of their excellent properties, such as non-toxic, non-volatile, non corrosive, good thermal stability and no two time pollution.
The largest consumption of inorganic oxide flame retardants is three oxidized two antimony, which can not be smoked and has certain toxicity. Its application is limited. Currently, it can replace three oxidation two antimony flame retardant, mainly including zinc borate, zinc stannate, molybdenum compounds and so on.
Zinc borate is a new type of inorganic flame retardant, which has a very promising future. It has no pollution, high efficiency and non-toxic, flame retardancy and smoke suppression and other environmental protection properties. With the deepening of the industrial countries, the zinc borate flame retardant used for polyolefin will be widely used and has a good market prospect in the world.
Zinc borate flame retardant, 250ml, 50ml, electronic balance, spherical condensing tube, vacuum drying box, three round bottom flask (500ml) and thermometer.
The main reagent of zinc borate flame retardant for polyolefin is seven zinc sulfate ZnSO4? 7H2O, borax Na2B4O7? 10h2o, anhydrous ZnO, and the above main reagents are all analytical purity.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
CAS No.:13674-87-8
HS: 29199000
Tax Rate (%): 9%
Tris (1,3-Dichloro-2-Propyl) Phosphate (TDCPP) Raw Materials: Phosphorus Oxychloride, Epichlorohydrin
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
The reaction equation for the preparation of flame retardants from zinc sulfate (ZnSO4? 7H2O) and borax can be expressed as follows:
7znso4+7na2b4o7+zno+20h2o=2 (4zno? 6b2o3? 7H2O) +7naso4+4h3bo3 was added to three flasks and added zinc sulfate solution. It was heated up quickly and stirred, and then borax and Zinc Oxide were added. Temperature control after a certain time of reaction, cooling, washing with water and ethanol respectively after filtration products, vacuum drying to obtain the product.
The synthesized in different process conditions between the flame retardant effect of flame retardant FB, after the initial synthesis experiment, the main factors for the temperature and reactant molar ratio, liquid-solid ratio and reaction time of four kinds of factors through orthogonal experiment, focusing on its effect on product performance, to determine the best process condition.
A flame retardant expert Peter Wittmann of the United States to the Beijing Institute of Technology lecture said that in 2001 the "9.11 incident, the plane hit the World Trade Center building is no use of flame retardant materials, the collapse of the building on fire with a flame retardant material than the north building collapsed earlier several minutes. "In this precious few minutes, how many people can escape! The importance of the flame retardant is here. "
The national standards for fire and flame retardants in the United States are very strict, and their law enforcement and surveillance are also in place. For example, when testing the flame retardant performance of a TV set, a burning candle will be poured on the TV, which will eventually burn the TV to a black hole, and it will not cause a fire. In the United States, 1 million TV sets were tested for flame retardancy in the United States, and no casualties were caused in the United States. The United States is not only so strict with its own products, but also for imported products.
There are a number of research and development institutes in China, which have been developed at the same time with the advanced countries, such as the State Key Laboratory of fire science and Sichuan University Key Laboratory of degradation and flame retardancy polymer materials, University of Science and Technology of China.
Flame retardant science and technology is a science that is developed to meet the needs of social safety in production and life, prevent fires and protect people's lives and property. Flame retardant is the application of flame-retardant technology in real life. It is a special chemical auxiliary used to improve the combustible and flammable materials combustion properties, and is widely used in the flame retardant processing of various decoration materials. The material processed by flame retardant can effectively prevent, delay or terminate the flame propagation when it is attacked by external sources of fire, so as to achieve the role of flame retardancy.
