2017-3-29 11:16:21
Polyurethane waterproof coating with crosslinking agent,A two-component polyurethane waterproof coating is a kind of two-component reaction type cross-linking synthetic polymer waterproof coating, component based on polyether resin and two cyanic acid by the polymerization of polyurethane pre polymers, component b by plasticizer, curing agent, crosslinking agent, promoting agents, filler and other additives is fine.
A kind of environment-friendly FeiJiaoYou polyurethane waterproof coating to poly (ethyl ester amino resin class a pre polymers is given priority to, and crosslinking agent on reaction.
Polyurethane waterproof coating with crosslinking agent of rubber with carbon black and stabilizer, flexibility, good extension performance, good tensile strength and tear strength is higher, the basic structure of the deformation has the strong ability to adapt, and cold resistant, high temperature resistance, ageing resistance, corrosion resistance and good performance.
Polyurethane waterproof coating
1. Do not contain coal tar excitant peculiar smell is small, less pollution to the environment.
2. Strong cohesive force, the liquid construction, room temperature crosslinking, convenient operation, short time limit for a project.
3. It has excellent extensibility, tensile strength, scale and cracking of waterproof subgrade deformation has a bridge role.
4. Can be in damp base on the construction of moisture content (< 50)
Polyurethane waterproof coating is a liquid film, free from the limitation of basic shapes, thus suitable for profiled roofing, complex parts and maintenance engineering (e.g., toilet bath room, kitchen, tunnel, swimming pool, basement, etc.).
Polyurethane waterproof coating construction method
At the grass-roots level surface should be strong, no sand, before construction should be on the surface of the dirt, dust, floating pulp, smeary clean, wipe out the bulge of mortar, cavity should be.
This coating A: part B = 1:2 (weight ratio), stir well.
With a scraper or Chinese lacquer brush with good coating batch or besmear to brush to the grassroots, and should be uniform and as far as possible make the formation of the coating thickness as consistent as possible.
Polyurethane waterproof coating construction usage: about 2.2 3.3 kg ㎡, should be 2-3 batch or besmear to brush, interval time is 24 hours (is not glue the hand), coating thickness of 1.5 -- 2 mm, can guarantee the quality of water project.
Waterproof layer of underground waterproof engineering, should try to do on the YingShui, avoid groundwater pressure caused the waterproof layer is water pressure stripping from the grassroots.
Within the storage period of bucket surface may form a film, is a normal phenomenon, it can be normal use after removal.
After open the barrel inside coating should run out as far as possible, otherwise, shall be immediately sealed preservation, in case in the barrel stated al.
Waterproof construction ventilation should be paid attention to.
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.
Coating bit bottom, loss of light white reasons:
(1) the lower level paint don't match, time is too short with high intensity between the layers on solvent dilution spray;
(2) the temperature is too low to spray the room humidity is too high, the poor ventilation environment cause lose luster paint film is white;
(3) add too much moisture is in paint and thinner, short film thickness;
(4) the construction site humidity is too high.
Prevention and control, and the solution:
(1) on the lower layer coating, interlayer construction time extended to dry and then spraying the second time, replace the dilution solvent.
(2) the construction site, ventilated environment, the best construction temperature control at 25 ℃ relative humidity around 70%;
(3) adjust viscosity of paint proportioning and construction (15 ", 17 ");
(4) construction, avoid the occasion of the humidity is too high and the weather.
