A flame retardant for polyurethane
Bromine flame retardant is an absolute advantage in organic polyurethane flame retardant, although it has been "controversial" on environmental protection, but it has been difficult to replace it with other polyurethane flame retardants.
In the non-halogen polyurethane flame retardant, red phosphorus is a good flame retardant, with the advantages of low additive, high flame retardant efficiency, low smoke, low toxicity and wide use.
Red phosphorus and aluminium hydroxide, expanded graphite and other inorganic flame retardants, use compound phosphate / / aluminum, magnesium, phosphorus, graphite and other non halogen flame retardant, can use flame retardant dose reductions and thus improve the processing performance and physical and mechanical properties of the plastic products.
However, ordinary red phosphorus is easily oxidized and hygroscopic in air, which can cause dust explosion, difficulties in transportation, and poor solubility of macromolecular materials. Application scope is limited.
Finding the balance between fire protection and environmental protection is an important node for future development of flame retardant products. The importance of flame retardants in modern society cannot be ignored. However, with the introduction of a series of environmental policies in Europe, the development of the flame retardants has been restricted to varying degrees. How to protect persons and property from fire threat at the same time, also can make the flame retardant to minimize the potential risk to the human body and environment, is the domestic flame retardant production enterprises, research institutes and downstream electronics electrical, building materials, transportation and furniture and other common focus of the industry.
There are also four chlorophosphate flame retardants (TCEP, TCPP, TDCP and v-6) currently in the eu risk assessment, mainly for polyurethane foam. The eu risk assessment for TCEP has been completed and needs to be announced. The risk assessment for TCPP, TDCP and v-6 is still ongoing in the human health and environment segment.
Any chemical can have both advantages and disadvantages to the human body and environment. The key is how to manage and properly use it, especially for flame retardants. We should base our conclusions on risk assessment, and in a scientific manner, let the flame retardant play its due role in the protection of human life and property. The ministry of public security will take effect next year -- the flame retardant standard for flame retardant products in public places.
Tris(2-chloroethyl)phosphate(TCEP)Use:
1. Tris (2-Chloroethyl) Phosphate Has Excellent Flame Retardancy, Excellent Resistance To Low Temperature And UV Resistance, The Steam Can Only Be Used At 225 ℃ Above The Direct Ignition Can Be Fired, But The Fire The Source Is Immediately Self-Extinguishing. This Product Is A Flame Retardant Not Only Can Improve The Material Level Of Flame Retardant Materials, But Also Improve The Flame Resistance Of Water Resistance, Acid Resistance, Cold Resistance And Antistatic Properties. Commonly Used In Flame Retardant Nitrocellulose And Acetate Fiber As The Substrate Of Paint Coatings, Unsaturated Polyester, Polyurethane, Acrylic, Phenolic Resin, Can Also Be Used For Soft PVC Plastic Flame Retardant. This Product Is Used For The Amount Of Unsaturated Polyester 10% To 20%, In The Polyurethane Rigid Foam (Flame Retardant Polyether As Raw Material) Can Be About 10% In The Soft PVC Used As Auxiliary Plastic Flame Retardant When The 5% To 10%. Flame Retardants, Uranium, Thorium, Plutonium, Technetium And Other Rare Metal Separation Solvent Or Extractant.
2. This Product Is Widely Used In Chemical Fiber Fabrics, Cellulose Acetate As A Flame Retardant, In Addition To Self-Extinguishing, But Also Improve Water Resistance, Cold Resistance And Antistatic Properties. The General Amount Of 5 To 10 Copies. This Product Is An Excellent Flame Retardant For Synthetic Materials, And Has A Good Role In The Promotion, Widely Used In Cellulose Acetate, Nitrocellulose Varnish, Ethyl Cellulose, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane, Phenolic Resin , In Addition To Self-Extinguishing Products, But Also Improve The Physical Properties Of Products, Products Feel Soft, Also Known As Oil Additives And Rare Elements Of The Extractant, And Flame Retardant Rubber Conveyor Belt Is The Main Flame Retardant Materials , The General Amount Of Added 5% To 10%.
3. Used As Additive Type Halogenated Phosphate Flame Retardant And Plasticizer. Molecules In Both Phosphorus And Chlorine, Flame Retardant Effect Is Remarkable, Not Volatile And Hydrolysis, Good Stability To Ultraviolet Light. Applicable To Phenolic Resin, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane And So On. Also Used As Nitrocellulose Coating Flame Retardant, PVC Flame Retardant Plasticizer, Metal Extractant, Gasoline Additives And Polyimide Processing Aids And So On. Can Improve Water Resistance, Weatherability, Cold Resistance, Antistatic Property. Reference Dosage 5% To 20%.
Flame retardant products shall be formulated by the ministry of public security of the public and component combustion performance requirements and identify "standard will begin early next year formally implemented, which puts forward higher requirements on plastic flame retardant performance. The standard is the ministry of public security in order to effectively control in case a fire occurs in a public places causing casualties and property losses, by the national fire standardization technical committee subcommittee fire materials under centralized management.
This standard has been clear about the public with the definition and classification of flame retardant products and components, combustion performance requirements and logo etc, provides for public use of building products, floor materials, wires and cables, sockets, switches, lamps and lanterns, plastic products such as home appliances shell, and chair, sofa, mattress used in the thermal insulation layer and the combustion performance of the foam plastic, put forward the corresponding requirement for flame retardant standard scale.
Polyurethane insulation construction has a clear flame retardant composition during construction, thus ensuring safety problems in construction, reducing unnecessary troubles and affecting work quality.
Phosphorus-containing (especially bromide) flame retardant due to C - Br key of key is low, the scope of its decomposition temperature is commonly used polymer decomposition temperature range, therefore, when polymer decomposition, bromine flame retardants are beginning to break down, to achieve the effect of synchronous flame retardant; At the same time, this kind of flame retardant can be used with other compounds, such as antimony trioxide, to improve the flame retardant effect through synergistic effect.
Therefore, the application of bromine flame retardant is very wide. It can be used in flame retardant most plastic varieties and is one of the largest organic flame retardants in the world. The main disadvantage of bromine flame retardant is to reduce the anti-ultraviolet stability of the flame retardant substrate, which generates more smoke, corrosive gas and poisonous gases when burned, and its use is limited.
