2017-3-26 20:30:53
Resin modified waterborne polyurethane coatings crosslinking agent,Randhir Parmar, such as epoxy resin and acrylic acid copolymer with ethylenediamine sealing side, the first to react with isocyanate prepolymer preparation of waterborne polyurethane coating.
DSC thermal stability test results show that the synthesis of waterborne polyurethane coating, scratch hardness up to 2600 g, acid-proof alkaline, water resistance, resistant to salt water performance is superior to common waterborne polyurethane coatings.
Single He Yu equal to tung oil acid resin modified waterborne polyurethane emulsion as basic material, anticorrosion pigment for organic modification of orthophosphoric acid zinc, aluminum alloy with waterborne polyurethane anticorrosion coating, and study the tung oil dosage of fat acid single gan, antirust pigment and YanJi quality ratio on the coating performance, coating adhesion biggest when YanJi ratio 1.2, 12.8 MPa, salt fog resistance (500 h) YanJi ratio 1.2 in coating without rust, scratches the one-way foaming within 2 mm.
Results show that when the mass fraction of tung oil acid single gan fat (20%) and YanJi mass ratio is 1.2, the optimal coating anticorrosion performance, and the aluminum alloy matrix adhesion strong, has potential application value in aluminum alloy on the truck.
Tang jiyang bisphenol A type epoxy resin as modifier, polyester polyol was prepared for waterborne polyurethane soft segment, and infrared spectrum analysis and particle size analyzer, the contact Angle meter and thermogravimetric analyzer characterization methods such as study of emulsion and film analysis, research shows that: the emulsion stability is good, the average particle size was 26.67 nm; Coating hardness of 2 h, bibulous rate is only 2.4%, heat resistance, corrosion resistance, excellent comprehensive performance of coating film.
Xu, etc, by using the method of in-situ polymerization and anionic emulsion with isophorone diisocyanate (IPDI), polyether polyols (NJ - 220), dihydroxy methyl butyric acid (DMBA), hydroxyl ethyl methacrylate (HEMA) as raw material, the preparation of methyl acrylic hydroxyl ethyl ester water-borne polyurethane resin coated, then, multifunctional acrylate and butyl acrylate as reactive diluent, 2 - hydroxy - 2 - methyl - 1 - phenyl - 1 - acetone (HMPF) as the initiator preparation by ultraviolet light crosslinking aqueous polyurethane coating, and to explore the protection performance of coating on metal surface,
The results showed that the preparation of uv crosslinking aqueous polyurethane coating on metal surface has a good protection, in the protection of cultural relics show that the iron has potential application value.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
The main purpose of the waterborne polyurethane coating agent as follows.
(1) polyurethane leather coating flexibility, abrasion resistance, can be used as a natural leather and artificial leather coating agent and patching agent. Our country since the 70 s, has the development of waterborne polyurethane leather finishing agent, in the late 80 s, the rapid development of the early 90 s, polyurethane crosslinker, type is given priority to with anionic polyether type, alternative acrylate resin emulsion used for leather finishing agent, dealing with a natural leather it overcome the acrylate resin "hot sticky cold short" shortcomings, wholesale polyurethane crosslinker, the finishing of the leather soft plump. It can be used with acrylate resin blend. Polyurethane coating leather ms can be used for boots shoes, clothing, bags, etc.
(2) coated fabric Can be used for a variety of fabric coating agent, such as canvas, fabric, conveyor belt, coating.
(3) fiber treatment cotton, chemical fiber by polyurethane emulsion dilute solution impregnation, dehydration, heat treatment, can improve the handle and crease resistance and preshrunk.
(4) nylon, ABS and other plastic coating surface coating.
(5) the floor coating Can be used for the gymnasium, indoor wood floor coating, coating of concrete floor, abrasion resistance, impact resistance, good gloss.
(6) other coating materials, such as paper coating, car inner decoration coating.
(7) bottom coating agent.
