How to control the reaction temperature when preparing Tris (2-butoxyethyl) Phosphate TBEP?
This material is made by using phosphoric acid and 2-butoxyethanol as raw materials and placing them in a stainless steel reactor. First, mix the raw materials in a ratio of 1:3, heat to 80 degrees, add a small amount of sodium hydroxide as a catalyst, and then slowly raise the temperature to 140 degrees. At this time, water begins to be generated and is collected through a condenser. The temperature must be stable in this range and cannot exceed 150 degrees, otherwise 2-butoxyethanol is easy to volatilize, which reduces the yield. Continue the reaction for five hours until no water is discharged. Just like controlling the temperature when boiling paste, if it is too much, it will burn, and if it is not enough, it will be raw. Only those who are precise can obtain Triis (2-butoxyethyl) Phosphate TBEP, and its liquid is clear and not turbid.
Why is Tris (2-butoxyethyl) Phosphate TBEP suitable as a flame retardant?
This product contains about 9% phosphorus. When it encounters fire, it can decompose to form phosphate esters, which cover the surface of combustibles and isolate oxygen. Combined with polyurethane foam plastics, adding 10% can make the foam pass the vertical combustion test, and the smoke density is low when burning, and there are fewer toxic gases than brominated flame retardants. In the flame retardant finishing of fabrics, it can penetrate into the fiber, and it is still effective after fifty washings, which shortens the afterburning time of cotton cloth to less than one second. It has both flame retardant and plasticizing functions, and no additional plasticizer is needed, so it can be used in a variety of materials.
What is the application of Tris (2-butoxyethyl) Phosphate TBEP in coatings?
Adding Tris (2-butoxyethyl) Phosphate TBEP to alkyd paint can reduce viscosity, improve leveling, and make the paint film smooth without brush marks. In amino baking paint, it can increase the curing speed, shorten the baking time by 30%, and enhance the toughness of the paint film and improve the impact resistance. It has good compatibility with pigments, and can disperse pigment particles during grinding, making the paint color uniform and not easy to precipitate. Used in fire-retardant coatings, it can be both flame-retardant and plasticizer, making the coating less likely to crack and having strong adhesion, so it is valued by the coating industry, especially for fire-retardant coatings for steel structures.
What is the difference between the solubility properties of Tris (2-butoxyethyl) Phosphate TBEP and TIBP?
Tris (2-butoxyethyl) Phosphate TBEP is slightly soluble in water, with a solubility of about 5%, while Triisobutyl Phosphate TIBP is almost insoluble in water, so the former is more suitable for water-based coatings. Among organic solvents, TBEP has better compatibility with alcohols and can be used in water-based inks; TIBP is more soluble in esters and is suitable for oily plastics. TBEP has a stronger solubility for resins and can dissolve some insoluble resins, such as polyvinyl acetate, while TIBP has a narrow solubility range, so the two have different application scenarios and need to be selected according to the type of solvent.
What are the taboos for storage and transportation of Tris (2-butoxyethyl) Phosphate TBEP?
This product needs to be stored in plastic barrels or iron barrels lined with plastic. Do not use pure iron barrels to prevent corrosion of the inner wall. The storage warehouse needs to be ventilated, the temperature should not exceed 35 degrees, and it should be kept away from oxidants and fire sources. It should not be transported in the same vehicle with strong acids. In case of leakage, it should be adsorbed with sand and soil, and should not be flushed with water to prevent diffusion. Its vapor is heavier than air, and it will accumulate in low-lying areas after leakage, so ventilation should be strengthened to disperse it. Wear rubber gloves when operating to avoid direct contact with the skin. If it splashes into the eyes, rinse with clean water immediately. Therefore, storage and transportation should be cautious to prevent damage and harm.
