ジメチルチオトルエンジアミンの用途PU防水素材

Our One Kind With E-300 As A Curing Agent, Has Good Mechanical Properties Of Low-Density Polyurethane Foam Molded Veins. Hydrogenated MDI As The Isocyanate Component Values, NCO Index Of 1.00, So That E-300 At 23 ℃ Mixed With 30s, When The Gel Division About 28 Min. So That 50 Parts Voranol 4703 Polyether Polyol, 50 Parts Voranol 4925 Polymer Polyol, 1.5 Parts Diethanolamine, 4.0 Parts Water, 4.0 Parts Of Niax Y-10184A, 1. 2 Parts Of Dabco 33 LV, 0 15 Parts Of Niax A-1 Catalyst, 2.5 Parts Of A Mixture Of E-300 And 49.1 Parts Mondur TD-80 (TDI-80) At 230C, 1200 Rev / Min Speed Mixing Under 4s, Then Poured Another Container Between The Milk-Mail Inch Observation Of 7s, Thickening Time Of 38 S, Free Rise Time Of 78 S, The Foam In Good Condition.


上記の成分は、非TDI、次に添加TDI-80混合し、1200 R /分の速度5sで攪拌されるように、反応混合物を金型を追加しました、密封した、2分オーブン8 60分に成形した後、その後℃、そして、25d、以下のようにして測定機械的特性をエイジング50℃と7%の相対湿度で得られた発泡体をストリップ..密度30 24キロ/ M3、引裂強度311 7 N / M、引張強度142.83キロパスカル、伸び108%の、25%のIFD 200。1キロパスカル、65%のIFD 600。3キロパスカル。

PU Coating With Excellent Softness, Durability, Widely Used In Waterproof Materials And Coatings And Other Fields. However, The Traditional Polyol Used In The Process As A Chain Extender, It Requires The Use Of A Catalyst At A Low Temperature Operation, As When Using MOCA Chain Extender Reaction Too Poor Heat Resistance And Mechanical Properties Of The Resulting Waterproof Material, PU Coating Of Poor Adhesion Between The Coating And Paint And PU Between.

A Safety Developed By Our Company, At A Low Temperature 0 ℃ Curing Excellent Properties, Coating Performance And Adhesion And Good PU Waterproof Material [35]. The Main Agent Composition With TDI Based Prepolymers, -NCO Content 1.500 ^ -6 .. %; Hardener Component Consists DMTDA And Other Aromatic Amines, The Acid Catalyst And The Molecular Weight <700 PPG Constitution. N (-NCO) N (-NHZ) _ (0. 8 ^} 3 0.): 1, PPG Amount Satisfies N (-NCO): N (-OH) = (.. 1 1 ^ 10 0): 1 The Catalyst Preferably Partial Organic Acid, Preferably In The Curing Agent Mass Fraction Of 0.0500 ^ 5.000. In Addition, The Formulation May Also Contain A Metal Catalyst, Plasticizers, Fillers, Antioxidants, Antioxidant, And Pigment. Construction, Mixing The Main Agent And Curing Agent, With A Roller Is Applied To The Material Required For Processing (Such As Concrete) Surface Of The Mixture At 20 ℃ Gel Time At 15 ^ -30 Min, Preferably Coated The First Two Days And Then The Next Step After The Construction, It Is A Good Balance Of Time And Curability. The Waterproof Material With Good Mechanical Properties And Heat Resistance.
