What is water-based glue, what is oily glue, you know? |
Public date:2018-7-27 Hits：3399 |
The water-based glue is obtained by emulsifying acrylic or polyurethane resin through a special emulsification device using water as a solvent. Its biggest advantage is: variety, environmental protection, price glue manufacturers are cheap, and now many coatings are made of water-soluble glue, such as: general water-soluble PA, water-soluble PU and film glue, oily feeling, scratching A functional slurry such as a slurry. Water solubility is the direction of coating in the future due to its functionality, environmental friendliness and low price. The disadvantages are poor film formation, poor washing fastness, and PU can not be attached to hot air glue.
The oily glue is obtained by dissolving acrylic acid or polyurethane in an oil solvent (toluene, DMF, methyl ethyl ketone, etc.) as a solvent. The advantage is that the film forming property is good, the fastness is good, and the PU can be attached with hot air glue, which is a coating glue which is generally used at present. The disadvantage is that due to the use of oily solvents, there is a lack of environmental protection, especially the current price increase of oil, which has led to soaring oil solvent prices. Most of the coating glues use too much oily solvents because of the high cost. Environmental protection is not up to standard, and with the further improvement of environmental standards in various countries, the environmental protection requirements for coated rubber are getting higher and higher. |
