Reactive type halogen-free flame retardant

Reactive type halogen-free flame retardant

HCA reactive halogen free flame retardant DOPO as phosphorus fe cyclic phosphate is organophosphate class, heterocyclic compounds with high thermal stability, oxidation resistance and excellent resistance to water, is reactive and adding flame retardant agent, mainly used for polyester type, polyurethane foam plastics, thermosetting resin and the adhesive, due to the reactive halogen free flame retardant - carbon bonds have phosphorus flame retardant performance is better than general phosphate.

According to expert introduction, HQ reactive halogen free flame retardant is A new type of phosphorous environmental halogen-free flame retardant, mainly used in high-grade with epoxy resin such as circuit board, can take the place of bromine flame retardants (tetrabromo bisphenol - A), can be used for encapsulation of semiconductor materials, printed circuit board, LED tube, etc., used must meet the ROHS requirements of products, intermediates for synthesis of reactive flame retardant agent and so on.

HCA reactive type halogen free flame retardant DOPO profile: chemical name: 9,10- dihydro-9 - oxygen-10 - phosphorus-10 - oxide; DOPO (DOP); Other name: commodity name HCA; Molecular formula: C12H9O2P; CAS: 35948-25-5; Molecular weight: 216.

HCA reactive halogen free flame retardant DOPO quality index: appearance: white chip/granule; Content: > 98.5% (HPLC); Melting point: 117 ~ 121 ℃; Chlorine content: no more than 200 (PPM); Phosphorus content: > 14%; Solubility: soluble in methanol, ethanol, chloroform, dimethyl formamide, dioxane ring. Soluble in benzene, insoluble in water, hexane;

Phosphors are organophosphorous heterocyclic compounds. According to the experts, it has high thermal stability, oxidation resistance and excellent water resistance. It is reactive type and additive flame retardant. Mainly used for polyester fiber, polyurethane foam plastic, thermosetting resin and adhesives. Since the flame retardant has phospho-carbon bonds, flame retardant performance is better than normal phosphate.

(1) reactive flame retardant for epoxy resin.

DOP and epichlorohydrin reaction and then react with hydroquinone, experts say, especially epoxy resin used as electrical insulating materials, semiconductor materials of sealing material, for electrical insulation, low volatile, less pollution, ABS, has good intermiscibility, forms after adding flame retardant transparent plastic;



Trixylyl Phosphate(TXP) Use

Phosphate Trisphenylene Phosphate Is Low, Resistant To Hydrolysis, Good Flame Retardant Can Be Used As Vinyl Resin, Cellulose Resin, Natural And Synthetic Rubber Plasticizer, Low Volatility, Good Water Resistance, Flame Retardant. Trichenylene Phosphate Use For Use In Combustible Turbine Oils, With Good Flame Resistance And Good Thermal Oxidation Safety, Good Lubricity, Extreme Pressure Antiwear Additives For Lubricants, Thickeners. Also Used For Fire-Resistant Turbine Oil, With Good Thermal Oxidation Stability, Lubricity, As A Lubricant Anti-Wear Additives, Plasticizers, But Also For Flame Retardant, Wear-Resistant, Resistant To The Mold Of The Cable, Ethylene Conveyor Belt, Artificial Leather, Foam, Flooring Materials, But Also In Metallurgy, Electricity, Mechanical Engineering And Other Aspects As A Fire-Resistant Hydraulic Oil.


(2) color inhibitor

ABS, AS, PP, PS, epoxy resin, phenolic resin, alkyd resin, surface active agent heat caused by heat, and polyurethane are colored by light and heat, adding DOP can prevent coloring.

Inorganic flame retardants in non-halogen flame retardants are an important component. High performance non-halogenated inorganic flame retardants can be added to polyolefin without affecting the mechanical properties of the products.

Development of heat resistant varieties) increase the aluminum hydroxide particles surface area, i.e. ultra-micronization model.the and superfine refinement, make the particle surface water vapor partial pressure drop, aluminium hydroxide can be improved heat resistance, and can make the material mechanical properties, flame retardant effect is obviously enhanced. The experimental results show that the average particle size of aluminum hydroxide is 5 mu m, and the oxygen index is 28, and the particle size is <1 mu m, and the oxygen index reaches 33.

Micral1000 and micral1500, nominal particle size of 1. 0 mu m, 1. 5 mu m, and narrow particle size distribution, can improve injection molding and extrusion processing technology. Hydrax series aluminum hydroxide has 5 varieties, all have extremely narrow particle size distribution range. The s-13 ultra-fine aluminum hydroxide particle size is 0. 2 ~ 0.5mu m.

The flame retardant of silicon series can improve the processing performance, mechanical property and heat resistance of the base material. Moreover, ecological friendly and flame retardant materials have better recycling effect and can meet people's strict requirements on flame retardants. However, its processing technology is more complex, large-scale application still has time.
