The difference between mobile phone protective film coating, water glue and oil glue: 1. Water-based coating glue is made by emulsifying acrylic or polyurethane resin through a special emulsification equipment with water as a solvent. Its biggest advantage is: variety, environmental protection, and low price. Nowadays, many coatings are made of water-soluble glue, such as: general water-soluble PA, water-soluble PU, film glue, oily wax feel, and color scraping paste And other functional slurry. Water solubility will be the direction of coating in the future due to its functionality, environmental protection, and low price. The disadvantages are poor film-forming properties, poor washing fastness, and PU cannot be pasted with hot air glue. 2. Oily coating glue: The oily coating glue is made by dissolving acrylic or polyurethane with oily solvent (toluene, DMF, methyl ethyl ketone, etc.) as the solvent. Its advantages are good film-forming properties, good fastness, and PU can be pasted with hot air glue, which is a commonly used coating glue at present. The disadvantage is that due to the use of oily solvents, there is a lack of environmental protection, especially now that the price of oil has risen, causing the price of oily solvents to rise sharply. Most of the coating glues are too expensive, so relatively poor oily solvents are used, resulting in Environmental protection is not up to standard, and with the further improvement of environmental protection standards in various countries, the environmental protection requirements for coating adhesives are getting higher and higher. 3. Hot-melt pressure-sensitive adhesive Hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, mainly composed of synthetic rubber, resin and rubber oil, etc., mixed and heated to a molten state and then coated on tissue paper, cloth or plastic film and other substrates. A new type of adhesive tape made from the above has its greatest advantage because of its low cost. The disadvantage is that its viscosity is significantly affected by temperature. Mainly used for all kinds of sealing, box sealing, paper packaging, beverage bottle labels, sealing aluminum foil, flexible packaging and other packaging; environmentally friendly paper pallets, etc., suitable for various materials. The sealing glue is used to bond all kinds of glazing, polishing, calendering, PP composites, such as PET, PP transparent boxes, films, non-woven products, cosmetic box packaging, food box packaging, cigarette box packaging, Tetra Pak beverage packaging, etc. , Assemble furniture edge banding, electronics industry, automotive interior sealing, car lamp manufacturing, windshield assembly, etc.), non-woven sanitary napkins, diapers, diapers, insoles, disposable daily necessities, coated composite label paper, labels Double-sided tape, mouse sticky board, fly paper, wooden floor, carpet adhesive, band-aid, medical breathable tape, color box packaging, carton packaging adhesive, adhesive tape and other difficult-to-stick materials have strong adhesion ; Good thermal stability, no impurities, good operability; Excellent weather resistance; Aluminum foil sealing hot melt adhesive has unique characteristics of water resistance and waterproofing. Hot-melt pressure-sensitive adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.
