Jingzhou fule how packaging adhesive jingzhou fule packaging glue very slightly soluble in water, soluble in many organic solvents.
Oily coating adhesive is oily solvent (
Toluene, DMF, butanone, etc. )
As a solvent, dissolve or polyurethane acrylate.
Its advantage is good film forming, good color fastness, PU can stick hot glue, is the current commonly used coating glue.
Defect is due to the use of the oily solvent, so environmental protection lacking a bit, especially now that oil prices, oil solvent prices soaring all the way, most of the coating glue due to the cost is too high, so use more bad of the oily solvent, leading to environmental protection is not up to standard, in addition with the national environmental standards to further improve, so for environmental requirements of the coating adhesive is higher and higher.
Flash point 10 ℃ (
Due to its extremely low water vapor transmittance, it can form a with elastic sealant excellent resistance to moisture system.
Hot melt adhesive is a kind of plastic adhesives, to a certain temperature range with the temperature change and change its physical state, and chemical properties unchanged, its non-toxic tasteless, environmentally friendly chemical products.
Is the use of hot melt glue by heating the hot melt adhesive, hot melt adhesive machine melt glue after become a kind of liquid, by hot melt adhesive machine hot melt rubber hose and hot melt glue gun, to be adhesive surfaces, hot melt adhesive cooling after completed the glue.
Boiling point l01 ℃.
Below is the hot melt sealant.
Water-based glue process characteristics can use a variety of hot melt adhesive lining cloth processing, almost all types of hot melt adhesive can be used, with much is ethylene -
Vinyl acetate (
Hot melt adhesive, polyamide hot melt adhesive and high-pressure polyethylene (
Hot melt glue powder, and different USES of hot melt adhesive and processing methods are also different.
(1) using water-based glue, in line with the shoe industry, a long-term trend in brands actively, water-based adhesive
has been widely used all kinds of shoe factory, water-based glue quality gradually progress and stability;
How about jingzhou fule packaging glue class acrylate pressure-sensitive adhesive by crosslinking state can be classified as crosslinking and crosslinking type;
According to the form and can be divided into the emulsion type and solvent type, hydrosol, to divest type, radiation type and hot melt type, etc. 6.
Such as water soluble or decentralized hot melt adhesive, hot melt sealant, hot melt pressure sensitive adhesive and so on.
(2) use water-based glue will lead to environmental protection, health, save energy, save cost of equipment and manpower, fire safety, etc;
Search the public number: WPU -
88 China adhesive platform 8 (3) cost: water-based glue consumption is 1/3 of solvent-based glue, if the water 3 times of unit price shall not exceed the solvent adhesive, replace solvent-based adhesive with water-based glue will not increase costs, as oil prices rise, the cost of the solvent adhesive is bigger than water-based glue rise, in the long run, water-based glue process cost lower than that of solvent adhesive process.
The use of hot melt adhesive technical indicators are as follows: appearance: white is slightly yellow granular or stick.
Water-based glue to introduce it to glass, aluminum alloy, galvanized steel, stainless steel and other materials have good adhesive properties.
How about jingzhou fule packaging adhesive compared with other pressure sensitive adhesive, acrylate pressure sensitive adhesive with the following features: almost without adding stabilizer has excellent weather resistance and heat resistance;
No phase separation and migration phenomenon, good transparency, good oil resistance;
No effect to the skin, suitable for field.
