2017-9-30 11:50:46
PP special green flame retardant is a non-halogen and expansive flame retardant for polypropylene. It is made with synergy of nitrogen phosphorous chemical polymerization, and good compatibility in polypropylene, little impact on the mechanical properties of the plastic, and has excellent process stability in machining process.
Special environmental protection PP flame retardants is different from containing halogen flame retardant agent, are produced in the combustion process through the expansion of the dense carbon layer to achieve the purpose of insulating air flame retardant, without stimulating halolide gases and smoke, is a kind of environmentally friendly flame retardant.
PP special green flame retardant processing method
1) after mixing with PP, add the extruder. The quantity added is 25% - 27%;
2) processing temperature suggested in 180-180 ℃. Due to the good thermal stability of this product, if the specific process needs, it can also be appropriately improved.
3) when mixing extrusion with PP, it is recommended to use twin screw extruder, preferably granulation on parallel twin screw;
Heating area 12345678
Temperature (140150175185185185185180 ℃)
4) recommend not to add any other inorganic fillers, because the packing will destroy the carbon structure and affect the flame retardant effect;
5) recommend not adding the lubricant of stearic acid;
6) if an antioxidant and light stabilizer are added, an organic antioxidant and light stabilizer should be used;
7) carefully evaluate PP special green flame retardants for mixing with other additives.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
Expansive flame retardant (IFR) is a kind of flame retardant with C, N and P core components. The IFR consists mainly of three parts:? Carbon source (carbonaceous) : generally containing carbon rich polyfunctional group substance, such as starch, pentaerythritol and diacyl alcohol; ? Acid source (dehydrating agent) : usually inorganic acid or salt, such as phosphoric acid and ammonium polyphosphate, can be formed in situ when heated. ? Air source (foaming agent) : a lot of nitrogenous polycarb, such as urea, melamine, dicyandiamide and derivatives.
Expansion type flame retardant mechanism of the flame retardant is in when heated, into carbon agent under the effect of acid source and dewatering into carbon, and in the gas from the decomposition of foaming agent, form fluffy perforated closed structure of carbon layer, carbon layer of polymer and the heat transfer between the heat source can be reduced, and prevent gas diffusion.
The polymer ended up burning because there was not enough fuel and oxygen. The world's commoditized expansive flame retardants have cn-329, and Borg-Warner is suitable for PP, which is stable at the processing temperature of PP and has good electrical properties. With the addition of 30%, the material oxygen index can be up to 34, and CN-329 is a good flame retardant of PP. It can be seen from the molecule that Melabis has a rich source of acid and carbon source, improved the ratio of source-source, carbon source, and gas source, so that Melabis has a much lower moisture absorption ratio than cn-329, which is an excellent flame retardant.
With the rapid development of flame retardants, the flame retardant technology is also rapidly achieving breakthrough. Including the surface modification technology, compound with collaborative technology, technology, super refining technology, microcapsules, macromolecular crosslinking technology got rapid development, such as the flame retardant, fire has played a very important role in my career.
The flame retardant can be divided into additive flame retardant and reactive flame retardant. Additive flame retardants are usually added to the base resin, and they are simply physical mixing with resin; Reactive flame retardants is commonly intramolecular monomer containing flame retardant elements and reactive groups, such as halogen acid anhydride, halogenated bisphenol a and phosphorus polyols, etc., because of the reactivity, can be chemically bonded to the resin molecular chain, become a part of the plastic resin, the most reactive flame retardant structure or synthetic additive flame retardant monomer.
