Phenolic resin flame retardant
Bakelite is also called bakelite, also known as bakelite powder. The original is colorless or yellow-brown transparent material, market sale often adds colorant and red, yellow, black, green, brown, blue and other colors, have grain, powdery. The weak acid and weak base are decomposed by strong acid. Insoluble in water, soluble in acetone, alcohol and other organic solvents. Phenol aldehyde or its derivatives are condensed.
Solid phenolic resin for yellow, transparent, amorphous block material, because contain free phenol and is slightly red, the proportion of entity an average of around 1.7, soluble in alcohol, insoluble in water, the water, weak acid and weak base solution stability. Resin produced by condensation of phenol and formaldehyde under catalyst conditions, neutralized and washed. Because of the different catalysts, there are two kinds of thermosetting and thermoplastic. Phenolic resin has good acid resistance, mechanical properties and heat resistance, and is widely used in anti-corrosion engineering, adhesives, flame retardant materials, grinding wheel and other industries.
Different types of phenolic resin flame retardants can be divided into gas theory, covering theory, thermal theory and chemical theory. Phenolic resin flame retardant can be divided into three types according to different classification criteria.
(1) flame retardants can be divided into halogen flame retardants, phosphor flame retardants, nitrogen flame retardants, phosphorus one halogen flame retardants and flame retardants, etc.
(2) it can be divided into three kinds of flame retardants, organic flame retardants and organic and inorganic flame retardants according to the different components;
(3) the flame retardant can be divided into additive and reactive type according to the different usage methods.
Liquid phenolic resin is yellow, dark brown liquid, such as: basic phenolic resin is mainly used as casting binder.
The most important feature of the phenolic resin is the high temperature resistance, which can maintain the stability of its structure and size even at very high temperatures. For this reason, the phenolic resin has been applied to some high-temperature fields, such as refractory materials, friction materials, binder and foundry industries.
An important application of phenolic resin is as a binder. Phenolic resin is a versatile substance that is compatible with all kinds of organic and inorganic fillers. The correct phenolic resin is designed and wetting speed is especially fast. It can also provide the mechanical strength, heat resistance and electrical properties of abrasive, refractory materials, friction materials and electric wood powder after crosslinking.
Water-soluble phenolic or alcohol-soluble phenolic resins are used for impregnating paper, cotton, glass, asbestos and other similar substances to provide mechanical strength, electrical properties, etc. Typical examples include electrical insulation and mechanical laminate manufacturing, clutch plates and automotive filters for filter paper.
Tris(2-chloroisopropyl)Phosphate(TCPP)
The product is used for the soft / hard polyurethane foam, with thermal and hydrolytic stability good, especially suitable for ASTME84 (Level 11) foam, with low viscosity unsaturated polyester resin in low temperature application and phenolic plastics at. This product is also used to grab the foam sealant and sheet production. For polyvinyl chloride, polystyrene, phenolic resin, acrylic resin and rubber, coating, flame retardant, also used for soft and hard polyurethane foam, epoxy resin, polystyrene, cellulose acetate, ethyl cellulose tree and phenolic plastics, polyvinyl acetate and gun type foam sealant production. Particularly recommended for rigid polyurethane foam has excellent thermal and hydrolytic stability is particularly suitable for ASTM84 (II), compound for polyurethane foam and unsaturated resin and phenolic plastics.
Due to the transport process to avoid collision damage, Tris2-chloropropyl phosphate TCPP packaging methods generally used 250KG galvanized iron drum.
Below to introduce some of Tris2-chloropropyl phosphate TCPP packaging:
Net weight 250KG/ galvanized iron drum (a small cabinet pallet loaded 20 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Company 1.5 hour drive from Shanghai, the general sent to Shanghai port, the goods from customs inspection to the fastest one week after, the slowest ten days.
In view of the domestic and foreign demand is relatively small clients, also can use 50KG plastic bucket.
If you have special requirements on the Tris2-chloropropyl phosphate TCPP packaging, please contact us, try to meet the packaging requirements of customers.
At the temperature about 1000 ℃ under inert gas conditions, phenolic resin will produce high carbon residue, which is beneficial to maintain the structure stability of phenolic resin. This characteristic of phenolic resin is also an important factor in the field of refractory materials.
Compared with other resin systems, the phenolic resin system has the advantage of low smoke and low toxicity. In the case of combustion, the phenolic resin system produced by scientific formulations will slowly decompose and produce hydrogen, hydrocarbons, water vapor and carbon oxides. The amount of smoke produced during the decomposition is relatively small and the toxicity is relatively low. These characteristics make phenolic resin suitable for public transport and safety requirements of very strict areas such as mines, guardrails and construction.
The phenolic resin after crosslinking can resist any chemical decomposition. For example, gasoline, oil, alcohol, ethylene glycol, oil and various hydrocarbons. Because of its resistance to chemical stability, suitable for making hutch appliance, drinking water purification equipment (phenolic carbon fiber), bakelite tea tray, tea set, and widely used in cans and cans (national standard GB 05009.069 2003), the liquid container, and other food and beverage packaging materials.
Heat treatment can improve the glass temperature of cured resin and improve the properties of resin. The glass temperature is similar to that of crystallized solid such as polypropylene. The initial vitrification temperature of phenolic resin is related to the curing temperature used in the initial curing stage. Heat treatment process can improve the liquidity of crosslinked resin further prompt response, at the same time also can remove residual volatile phenol, reduce shrinkage, enhance the dimensional stability, hardness, and high temperature strength. The resin also tends to shrink and crispy. The heating curve of resins will depend on the initial curing conditions and resin system of the resin.
The phenolic foam is a kind of foam that is made from phenolic resin through foaming. Compared with the early market dominance of polystyrene foam, polyvinyl chloride foam, polyurethane foam and other materials, it has special excellent performance in flame retardant. Its light weight, big rigidity, good dimensional stability, resistance to chemical corrosion, good thermal stability, flame retardant, self-extinguishing, low smoke, flame penetration resistance, meet fire with no falls, the price is low, are electrical appliances, instrumentation, construction, petroleum chemical industry and other industries ideal insulation heat preservation material, thus attracting widespread attention.
