How daqing henkel glue daqing henkel glue environmental protection, high efficiency, low cost, simple process of the development of the reactive flame retardant has great prospects for development. ( 1) Adjust the structure under the premise that guarantees the stability of the emulsion, the content of hydrophilic group as low as possible, can improve the water resistance of the film; At the same time, under the certain condition of constant temperature heating for a period of time, the chromaticity and salary increase a certain range. ( 1] ( 2) Acetone method: first made high viscosity polymer, plus acetone viscosity reduction, with a hydrophilic monomer, chain extender, join the water under the high speed stirring, through strong shearing action to disperse in water, emulsion after vacuum distillation recycling solvent is made of PU water dispersion system. ( 2) Improve process using performance excellent emulsifying equipment for heat treatment, can improve the strength and water resistance of film. Hot melt adhesive machine of softening degree requirements at 80 ~ 90 ℃. In the process of heating for a long time, do not produce adhesive solution change color, in use process surface crust. Into the glue guns opened the package, in the packing of the hot melt glue guns tend to have a little support, the small bracket installation in gun two holes on the surface of the whole. ( 3) Compound modification to improve some properties of the waterborne polyurethane, and other water-based resin such as epoxy resin emulsion, urea-formaldehyde resin, such as blending, made the new water-based adhesive, its performance is improved. In order to make better play to the 'sticky' hot melt adhesive, adhesive industry experts warm reminder, when choosing hot melt adhesive should carefully consider the following factors: 1, EPE packaging industry, electrical appliances, shockproof anti-throw EPE packaging materials packaging assembly parts, electrical appliances manufacturer for rubber end users without peculiar smell, and in the production of EPE packaging manufacturer assembly process, coating machine is open, a local heating temperature is high, production workers allergic to special smell, think there's a smell is poisonous, the influence is healthy, require a safe working environment, so the smell of extremely strict requirements are put forward for hot melt adhesive, require hot melt adhesive has no smell. ( 4) Grafting modification are just the right amount of styrene monomer are added into the polyurethane emulsion, made by in-situ poly polyurethane grafted styrene emulsion, improves the adhesion and water resistance. How about the daqing henkel glue [ 2] Performance measurement requirements type editor CS501 super constant temperature trough, D25 - Type electric mixer, speed controller, oven, balance, three flask, drip tube, thermometer, beaker, measuring cylinder, pipette, washing ears ball, Fourier infrared spectrometer in spite of the existing reactive flame retardant effect is limited, but the reactive acrylate pressure-sensitive adhesive performance still has a lot of advantages in various aspects, flame retardant pressure sensitive adhesive huge market for its research and development also brings a lot of power. ( 5) Vinyl emulsion dispersion modified isocyanate (can be Or its pre polymers) Organic solution dispersed in the aqueous solution of polyvinyl alcohol, carboxymethyl cellulose daqing henkel glue? ( 3) Sealing and isocyanate method: choose the blocking agent of the right to water sensitive side - isocyanate NCO groups protected, make its loss of activity, add extender chain agent and crosslinking agent, a total of milk made from latex when used by a certain temperature and special catalyst demasking, generating - NCO terminal base, the preparation of waterborne polyurethane aqueous polyurethane chain extender to exist shortcomings edit waterborne polyurethane adhesives drying speed is slow, the nonpolar base material in poor wettability and low initial viscosity and poor water resistance, etc. All landowners with pneumatic stirrer, set of mixing time, under the 300 ∽ 500 RPM speed, stirring for 10 minutes. Pet-name ruby water-based adhesive and curing agent itself resistance to yellowing effect is very good, use water-based glue then the yellowing of shoes with other factors, such as agents, UV irradiation and so on. Daqing henkel glue what note appearance milky white or light yellow latex product characteristics this product according to the effect of the process to adjust the indicators, when using, do not add water or other solvents used to maintain good health 20 kg, 50 kg bottled product features look milky emulsion (2) resin pressure-sensitive adhesive used this kind of pressure sensitive adhesive resin of polyacrylic acid ester, pu, PVC, polyvinyl ether, etc. Hot melt adhesive for now, the definition of domestic adhesive manufacturers have thousands of, in front of the interests of many businesses shoddy, and hot melt adhesive with different affinity of different adhesive materials.
