Environmental friendly flame retardant for epoxy resin
HS-PNP-A is a kind of environmental friendly flame retardant epoxy resin, meet the requirements of ROHS. Epoxy resin used as an environmentally friendly flame retardant HS-PNP-A is a large molecular structure of nitrogen and phosphorus, and combined with nano embedded dispersion technology, showing amazing dispersion in transparent materials, can retain the original transparency of some materials.
Compatibility with environmentally friendly flame retardant material with excellent epoxy resin has excellent dispersibility, minimal environmental friendly flame retardant epoxy resin used for mechanical properties, no moisture absorption phenomenon, surface slip, excellent flame retardant performance, good thermal stability. During the combustion process, the expanded carbon layer is formed to achieve heat insulation, oxygen separation, and further diffusion of the surface flame, so as to achieve fire prevention and flame retardance, and low smoke, non-toxic and non molten drops.
HS-PNP-A products: appearance: white fine powder. P > 19%: nitrogen: > 22% decomposition temperature (c) > 293. Solubility: insoluble in water. Residual water content is less than 0.15 and average particle size is less than 10um
HS-PNP-A product characteristics: 1. This product is white powder phosphorus nitrogen intumescent flame retardant. It has the advantages of low smoke, low density and so on. 2, environmentally friendly halogen, in line with the EU ROHS standard, 3, high thermal stability, fully meet the PA6 forming processing temperature requirements, 4, excellent flame retardant effect.
HS-PNP-A application advice 1, after opening the package proposal as soon as possible, or recommend the use of 120 degrees bake for 2 hours. 2. It is suggested that pre drying resin should be made before the processing so that the moisture content in the resin must be lower than 0.5%, so as to prevent the color change caused by the hydrolysis of the resin at high temperature. 3, middle fire retardant was in order to discharge residual moisture in the resin. 4, to ensure the full dispersion of flame retardant, while maintaining a certain degree of vacuum. 5, unable to contact the halogen flame retardant, to prevent the product color change. 6. The flame retardant is most suitable for the equipment with weaker shear strength (such as shear block angle 30 or 45 degrees), which can make the product have better mechanical properties and good appearance.
The application of HS-PNP-A reference formula: 1, formula: PA6 55% glass 25% flame retardant 25% processing temperature: 220-230 degrees
Performance: UL94V-0 (1.6mm) 130Mpa 160MPa tensile strength flexural strength of unnotched impact strength 34
Formula: PA6 49% flame retardant 21-22%% glass fiber 30% processing temperature: 210-230 degrees performance: UL94V-0 (1.6mm) tensile strength 146mpa, bending strength 194mpa notched impact strength 10.3, bending modulus 8699
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.
Halogen antimony flame retardant polymer materials at present there are extensive application and research. Although the addition of flame retardant polymer materials to improve flame retardant performance, but its mechanical properties are usually reduced. The main reason resulting in the decrease of halogen material, antimony flame retardant performance is due to the poor compatibility of Sb2O3 and.
In order to improve the compatibility between Sb2O3 and matrix, the coupling effect between polymer coupling agent and low molecular weight organic coupling agent was compared. Although the latter can improve the dispersion of filler, but can not improve the impact strength of the composite. The PP is filled with silane coupling agent Sb2O3, the mechanical performances are limited. To this end, has studied the flame retardant and mechanical properties of macromolecular coupling agent modified halogen antimony flame retardant PP, results show that macromolecular coupling agent can improve the oxygen index of flame retardant PP, thermal stability, improve the compatibility of Sb2O3 and PP, making the Sb2O3 more evenly dispersed in PP matrix, better play synergistic effect with halogen flame retardant, so as to improve the mechanical properties of flame retardant PP.
The National Environmental Protection Agency has issued a draft rule to find safer alternatives to the flame retardant chemicals, six bromo cyclic alkanes (HBCD), in polystyrene building insulation materials (twelve).
EPA said the draft reference to enterprises, government, academia and the environmental organization's opinion in the formulation process. In the report, according to the current production process, there are only two kinds of feasible HBCD flame retardant alternative materials for foaming and extrusion PS foam insulation material.
EPA says it's looking for alternative materials for HBCD because it has "permanent, bioaccumulation, and toxic properties."".
EPA specifically mentioned an alternative, butadiene styrene brominated copolymer, which is expected to be safer than HBCD, and currently has commercial production conditions in the United states. Another alternative to the proposed four tetrabromobisphenol A (TBBPA) - bromo ether derivatives.
Flame retardant resin can make the wood burning an hour late. From the experimental point of view, flame retardant wood encountered after the fire, the flame retardant will release a sheet of non combustible gas, the wood in the fire can be well maintained for half an hour to an hour or so, even if the surface of the wood was burnt, inside is still intact.
