Fire retardant for wood
In the flame retardant industry, the application of wood flame retardants is the most widely used in the aspects of cost, source and use. Here's a summary of the common use of wood flame retardants.
(1) basic chemical properties are divided into inorganic flame retardants and organic flame retardants.
(2) the combination of flame retardant elements or flame retardant elements, including phosphor flame retardants, nitrogen retardant, halogen flame retardants, etc.
(3) the method of adding flame retardant to the material is divided into additive and reactive flame retardants.
(4) according to the compound type, it can be divided into acid, alkali, ether, ester, oxide, hydroxide, salt and other flame retardants.
(5) the action mechanism can be divided into physical or chemical active flame retardant, gas phase or coagulation phase retardant.
(6) the durability characteristics of flame retardants are divided into flame retardants such as light resistance, heat, chemicals and water.
Although the classification of wood fire retardant, many real application to practice is of excellent characteristics, not only has the properties of flame retardant, and considering the fire retardant, smoke, village, environmental characteristics, such as anticorrosion, insect sex affiliated, also conforms to the national policy and law, comprehensive consideration, to develop new varieties of wood fire retardant is flame retardant the difficulties faced by enterprises.
The purpose of the flame retardant technology is to make non-flame retardant material, which has the performance of flame retardant, which is not easy to burn or self-extinguishing under certain conditions. Non-flame retardant materials have the characteristics of flame retardant, the most direct method is to add flame retardant to the material. The fire retardant mechanism and classification of flame retardant are described below.
1. The flame retardant is used to carbonize the burner, thus achieving the flame retardant effect. The flame retardant effect is mainly played in solid phase, and the flame retardant materials of this category are mainly phosphor flame retardants (including organophosphorus and inorganic phosphorus).

Compatible, Insoluble In Aliphatic Hydrocarbons, Almost Insoluble In Water, And Hydrolytic Stability Is Good, In Alkaline Solution In A Small Amount Of Decomposition, The No Obvious Corrosion Of The Product.
Tris (2-Chloroethyl) Phosphate 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%.
2. The flame retardant is formed in the combustion condition to prevent the flame retarding. The flame retardant effect is mainly played in the liquid phase. The flame retardant materials of this category mainly include borate, halide, antimony oxide and phosphorous materials, or the materials between these materials to reflect the generated material.
3. Dispersion of combustion heat and dilution of combustible materials. This kind of flame retardant material is mainly borate zinc, aluminum hydroxide, magnesium hydroxide and other substances, mainly because of the decomposition of a large amount of heat absorption, the production of the non-combustible material diluting combustible gas to achieve flame retardant purpose.
4. Flame retardant decomposition products cut off the hydrogen-oxygen free radical chain reaction to the flame retardant purpose. The flame retardant effect is mainly played in the gas phase. This kind of material is mainly used in the gas phase. This type of flame retardant material is mainly halide and antimony oxide.
The environmental protection of flame retardants is not determined by any organization or environmental label, but is determined by the structure and performance of the flame retardant itself. Environmentally friendly flame retardant must meet the following three conditions: first, must be a green flame retardant PBT material (PBT: Persistent, bio - accumulative and toxic)), namely the release of chemicals to the environment do not have persistence, bioaccumulation and toxicity, at the same time should be the CMR substances (CMR: Carcinogenic, mutagenic or toxic for reproduction), namely no Carcinogenic and mutagenic and reproductive toxicity to human body, etc; the influence of Second, green flame retardant throughout the product life cycle, both in the upstream raw material extraction, or production transportation or recycled downstream link, the environmental impact of the youngest, environmentally friendly flame retardant to cope with environmental release small, in the life cycle of internal friction to emit less and easy recycling; Finally, green flame retardant must meet the regulatory and performance requirements of relevant regulations.
As the application of high polymer materials is becoming more and more widespread, and the environmental protection is becoming more and more popular, the flame retardant performance of materials is also higher and higher.
