Water-based coating adhesive is made by emulsifying acrylic or polyurethane resin through special emulsification equipment with water as solvent. Its biggest advantages are: many varieties, environmental protection, and low price. Nowadays, many coatings are made of water-soluble glue, such as: general water-soluble PA, water-soluble PU, and film glue, oily waxy feeling, and scraping paste And other functional slurries. Water-soluble, with its functionality, environmental protection, and low price, will be the direction of coating in the future. Disadvantages are poor film formation, poor washing fastness, PU can not stick hot air glue.
Oil-based coating adhesive is made by dissolving acrylic or polyurethane by using oil-based solvents (toluene, DMF, butanone, etc.) as solvents. Its advantages are good film-forming property and good fastness. PU can be attached with hot-air adhesive, which is currently widely used coating adhesive. 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, which has caused the price of oily solvents to rise all the way. The environmental protection is not up to standard. In addition, with the further improvement of environmental protection standards in various countries, the environmental protection requirements for coating adhesives are becoming higher and higher.
Hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, which is mainly made of synthetic rubber mixed with resin and rubber oil and heated to a melted state and then coated on cotton paper, cloth or plastic film and other substrates. The new type of adhesive tape, low cost is its biggest advantage, the defect is that the viscosity is significantly affected by temperature. Mainly used for various types of box sealing, box sealing, paper product packaging, beverage bottle labels, sealing aluminum foil, flexible packaging and other packaging; environmental protection paper pallets, etc., adapting to various materials. Sealing glue for various PET, PP transparent boxes, films, non-woven products such as glazing, polishing, calendering, PP compounding, cosmetic box packaging, food box packaging, cigarette box packaging, Tetra Pak beverage packaging, etc. , Assembly of furniture edge banding, electronics industry, automotive interior sealing, lamp manufacturing, windshield assembly, etc.), non-woven sanitary napkins, diapers, diapers, insoles, disposable daily necessities, coated composite label paper, labels Double-sided tape, sticky mouse board, fly paper, wooden floor, carpet glue, band-aid, medical breathable tape, color box packaging, carton packaging glue, 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 water resistance and waterproof characteristics. Hot melt pressure sensitive adhesive is a plastic adhesive. Its physical state changes with temperature in a certain temperature range, and its chemical properties remain unchanged. It is non-toxic and tasteless, and it is an environmentally friendly chemical product.
