Waterborne epoxy resin flame retardant
2017-11-3 10:59:55
Waterborne epoxy resin flame retardant began in the last century. With the progress of research, waterborne epoxy resin flame retardants become more and more environmentally friendly and more flexible.
Add type waterborne epoxy resin flame retardant by physical method is introduced to the polymer, but poor compatibility, flame retardant effect not lasting; reaction type waterborne epoxy resin flame retardant is phosphorus containing flame retardant monomer and polymer monomer copolymerization, the flame retardant group by polymer chain or side chain, the body of flame retardant polymer covalently combined, the resin can have lasting flame retardant effect, and can keep the thermal properties and mechanical properties of the original resin etc..
At present, the commercial type I waterborne epoxy coating curing agent is mainly composed of some salt modified polyamide curing agent. The cured coating has the disadvantages of slow drying coating, short construction period and hard coating.
ABA type amino terminated epoxy amine adduct was synthesized by reaction of two ethylene three amine and liquid epoxy resin (E-51), and then the primary amine was blocked completely with single epoxy compound, and its reactivity was reduced.
Contains a large number of secondary amine epoxy amine adduct still has a strong activity, therefore using acetic acid and part of secondary amine curing agent, further reducing the reaction activity, while adjusting the hydrophilic / hydrophobic balance curing agent reaches better compatibility with epoxy resin. Using ordinary short chain fatty alcohol diglycidyl ether or aromatic alcohol glycidyl ether end, it is difficult to achieve better emulsification and curing function, and the cured film is also crisp and hard.
Using a new type of single epoxy compounds were terminated (such as long chain fatty alcohol glycidyl ether and multi branched single epoxy compound etc.), in order to improve the emulsifying curing agent and curing performance, and the introduction of flexible chain segments in the main chain curing agent solution to the common type epoxy coating too high hardness, flexibility and resistance the impact of poor ills.
Experimental raw materials. Epoxy resin E-51: industrial products; two ethylene amine: three pure chemical analysis: pure; acrylonitrile; butyl glycidyl ether: industrial products; phenyl glycidyl ether: industrial products; long chain fatty alcohol glycidyl ether: industrial products; single mutilinked epoxy compounds: industrial products; analysis of pure acetic acid.
Experimental instrument. Four flasks; agitator; condensing tube; thermometer; electric heating sleeve; water bath thermostatic bath; vacuum pump.
Testing methods and equipment. Viscosity: the NDJ rotary viscometer determination; hardness determination by GB/T1730 - 93 type QHQ-A film scratch hardness tester; gloss: according to GB/T1743 (89 - 79) was determined by GZ- type photoelectric glossmeter; adhesion: according to GB/T1720 - 79 (85) were measured by QFZ- II adhesion tester; impact resistance: GB/T1732 - 93 is determined by the Q153-3K1 impact; flexibility: according to GB/T1731 - 93 with TQT-1 elastic film detector determination; thickness: according to GB12334 - 90 magnetic thickness tester; particle size distribution determination using JL-1155 laser granularity instrument; thermal stability: determined by TAS100 thermal analyzer.
Determination of amine value. The contents of primary amine, secondary amine and tertiary amine in the product were determined by ASTMD2074 - 66 standard.
Modified polyamide, is in a different method to obtain some performance improved with different degree of poly phthalocyanine, such as enhanced polyamide copolymer. Acid amine, F} filled polyamide and polyamide alloy, but the as curing agent of epoxy resin, and has good operability of modified polyamide.
The purpose of the modification is to reduce the volatility, reduce the irritation to the skin, improve the safety and hygiene, and improve the compatibility with the epoxy resin and the adjustable speed of curing. The epoxy compound addition, Michael (Michael) addition reaction, Manihi (Vlannici-}) reaction, ketone or shuttle acid reaction were prepared.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
(A Small Cabinet Loaded With 16 Tons), 1000KG / IB Bucket (A Small Cabinet Installed 18 Tons) Or 23 Tons (1, 3-Dichloro-2-Propyl) Phosphate (TDCPP) Packing: Net Weight 200KG / ISOTANK.
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.
A waterborne epoxy coating was prepared by capping and salt forming reaction by the reaction of low relative molecular mass liquid epoxy resin with two ethylene three amine to produce amino amine epoxy amine adduct.
The effects of different sealing agents on the properties were studied, and the optimum synthesis process was determined. Through introducing the new capping agent can greatly improve the emulsifying properties of curing agent (emulsion particle size as small as 1183 mu m) and curing performance, at the same time to solve the common type of waterborne epoxy coating hardness is too high, disadvantages of poor flexibility and impact resistance.
Epoxy coatings have excellent physical and chemical properties, which have been widely used in anti-corrosion coatings, industrial floor coatings, building coatings and other fields. But the epoxy coatings are mainly solvent based coatings. With the increasing demand for environmental protection, coatings workers all over the world are committed to the water-borne.
The research of waterborne epoxy coatings started in 1970s, and has been developed for 4 generations. For example: WATER2POXY1401, WATERPOXY1402, EPI-REZWD-510, EPI-REZ3510-W-60. But there are few reports on the production of this kind of goods in china.
Epoxy resin paint is a kind of coating material with epoxy resin as main film forming material. There are many kinds, each has its own characteristics. Dry type, two-component and multi component liquid epoxy coatings are classified according to curing methods; bake type single component and two-component liquid epoxy coatings; powder epoxy coatings and radiation cured epoxy coatings. According to the state of coatings, there are solvent type epoxy coatings, solvent-free epoxy coatings and waterborne epoxy coatings.
All kinds of characteristics are summarized as follows: strong adhesion, chemical resistance, corrosion resistance, water resistance, thermal stability and electrical insulation. It is widely used in building, chemical industry, automobile, ship, electrical insulation and so on. The paint by the outdoor sun will lose powder, to be used as a primer for appropriate.
