Environment-friendly flame retardant containing halogen and halogen free
Developed abroad are various including environmentally friendly flame retardant containing halogen and halogen free, they, too, for a lot of relevant material has a relatively high flame retardant efficiency, and environment-friendly containing halide and halogen free flame retardant can make mechanical performance is very good, appearance is also very good flame retardant material, but perhaps because of price and technical aspects of reasons, at present in China is not very good.
As an environmentally friendly flame retardant with halogen and halogen-free performance, it is generally believed that:
With high flame retardant efficiency, it can easily make the flame retardant grade of flame retardant.
The physical properties of the materials are less affected, and the physical properties of the flame retardant materials manufactured after use should not be changed too much.
It has good compatibility with materials and can be distributed evenly in the flame retardant materials and has a good affinity.
The processing technology is feasible and the traditional process can be used.
The price can be affordable, with high cost performance, and the cost of flame retardant materials can be accepted by the market.
Environmental protection, no toxicity, no release of harmful substances;
Mature inorganic flame retardant products, such as: antimony trioxide, magnesium hydroxide, such as some prices are relatively cheap, such as magnesium hydroxide, aluminum hydroxide not only low prices and combustion flame retardant materials do not produce a lot of smoke, such as water and carbon dioxide emissions are mainly will not cause significant damage to the environment material, so belong to product of green environmental protection, however, this kind of flame retardant fatal defect is flame retardant efficiency is low, need high amount to make flame retardant materials, the compatibility of thermoplastic resin and inorganic flame retardants have organic matter is very poor, not easy to disperse in the resin, even dispersion, affinity is not good, so making the material mechanics performance can often be difficult to accept, or greatly reduce the shock resistance of the material, or loss of the flexibility of the material, a variety of reasons lead to the limitations of the application, thus tends to be on the occasion of material mechanics performance requirements is not high.
Tris(2-butoxyethyl)phosphate(TBEP)Use
This Product Is Flame Retardant Plasticizer, Mainly Used For Polyurethane Rubber, Cellulose, Polyvinyl Alcohol And Other Flame Retardant And Plasticized, With Good Low Temperature Characteristics. Use Of Tris(2-butoxyethyl)phosphate(TBEP) For Flame Retardant Plasticizers And Processing Aids For Rubber, Cellulose And Resins. It Is Recommended For Use In Acrylonitrile-Based Rubbers, Cellulose Acetate, Epoxy Resins, Ethylcellulose, Polyvinyl Acetate And Thermoplastic And Thermoset Polyurethane. Phosphobutyrate (TBEP) Is Also Used As A Defoamer (Antifoam Agent) In Coatings, Detergents And Textiles. Has A Good Low Temperature Characteristics. This Product Can Also Be Used For Nitrocellulose, Ethyl Cellulose, Acrylic Plasticizer, Can Make Products With Transparency And Good Resistance To UV Performance.
Inorganic flame retardants, of course, such as antimony trioxide, zinc borate and often are used as flame retardant material, but their fire retardant effect mainly reflects in assisting other phosphorus-containing flame retardant flame retardant, its flame retardant efficiency is very low, or almost none.
Aluminum hydroxide is the three hydrated alumina (ATH), which accounts for more than 4o % of the total amount of flame retardant. The ATH itself has fire retardant, smoke and fill three functions, because it is not volatile, non-toxic, and can produce synergistic flame retardant action with a variety of substances, it is known as inorganic flame retardant. However, ATH has a large number of defects, and it usually requires more than 5O % to show the best effect. In order to overcome this shortcoming, it can be used to improve the granulation technology, to develop in the direction of ultrafine, to narrow the distribution of grain size. Improved coating technology to improve its dispersion in polymer; The method of macromolecular bonding method is used.
Organophosphorus flame retardant DMMP is colorless transparent liquid. Relative density (25 ℃) 1. 160 + 0. 1 005, viscosity (25 ℃). 75 mpa? S, freezing point < - 50 ℃, boiling point l80 ℃, flash point (opening) 90 ℃ or higher, acid value is 1 or less. 0mgKOH/g, the phosphorus content is 25%, and water is less than 0. > 05%, the decomposition temperature of 180 ℃. Can mix with water and a variety of organic solvents. Low toxicity. Used as additive flame retardant, suitable for unsaturated polyester, epoxy resin, phenolic resin, furan resin, polyurethane, etc.
Because of the development tendency of polyphosphate (abbreviated APP) for the development of the flame retardant without halogenation, it has become a hot field in the development of flame retardant at home and abroad.
In APP five different crystalline forms (Ⅰ - Ⅴ type), the crystallization of the high degree of polymerization of type II in the case study of ammonium polyphosphate. The degree of polymerization, significantly higher decomposition temperature, and good thermal stability, low solubility in water, is a kind of environmental friendly high efficient inorganic flame retardants, alternative containing halogen flame retardants, widely used in polyester, polyolefin plastics, rubber, high-grade expansion type fire retardant coatings, etc.
The low hydrated zinc borate has the function of high temperature, flame retardant, sterilization, anti-rust and smoke suppression. It is not toxic and cheap. The basic raw materials of boron ore are abundant in China, and the reserves are 40000kt (in B2O3). Recently, tens of thousands of tons of bornite have been found in Tibet, with a 30% grade and a magnesium content of more than 15%.
