White latex can be cured at room temperature with high curing speed and high bonding strength. The adhesive layer has good toughness and durability and is not easy to age.
The adhesion of white latex to hand-made hard-shell paper is also relatively strong.
Extended data:
First, the characteristics of white latex:
Using water as dispersion medium, it is obtained by emulsion polymerization, which is a water-based environmental-friendly adhesive. It is widely used in wood, furniture, decoration, printing, textile, leather, paper making and other industries because of its advantages such as good film forming, high adhesive strength, fast curing speed, good acid resistance, good alkali resistance, convenient use, low price and no organic solvent.
Second, the performance of white latex:
1, white latex has a series of advantages such as curing at room temperature, faster curing speed, higher adhesive strength, better toughness and durability of adhesive layer, and less aging. It can be widely used to bond paper products (wallpaper), and can also be used as waterproof coating and wood adhesive.
2. It uses water as dispersant, which is safe to use, non-toxic, nonflammable, convenient to clean, cured at room temperature, and has good adhesion to wood, paper and fabric and high bonding strength. The cured adhesive layer is colorless and transparent, with good toughness and no pollution to the adherend.
3. It can also be used as a modifier for adhesives such as phenolic resin and urea-formaldehyde resin, and used for manufacturing polyvinyl acetate latex paint.
4. The emulsion has good stability, and the storage period can reach more than half a year. Therefore, it can be widely used in printing and binding and furniture manufacturing, and can be used for bonding paper, wood, cloth, leather, ceramics and so on.
Three, white latex matters needing attention:
1, bonding operation, the use temperature shall not be lower than 7 degrees Celsius; Not resistant to high temperature, more than 95 degrees Celsius, will lead to a decline in the strength of the adhesive layer.
2. According to different uses, white latex can be diluted with water, but it needs to be heated to above 30 degrees Celsius first, and then slowly added with water above 30 degrees Celsius, and then it can be used after being evenly stirred. Dilution with cold water below 10℃ is not allowed.
3. After use, cover tightly. In order to prevent crusting, sprinkle a layer of water and mix well when using. Adding a small amount of hydrochloric acid before use can improve the curing speed.
4. It can be mixed with other hydrophobic resins to make a two-component product, which improves the adhesive strength, water resistance and heat resistance of the product and shortens the curing time.
5. White latex is generally safe, but it can't be swallowed or splashed into eyes. If you accidentally touch your mouth or eyes, please rinse with plenty of water immediately.
6. Don't pour white latex into rivers or sewers to avoid polluting or blocking sewers. The residue after use is left standing and stored, dried and formed into a film, and then treated as solid waste.
7. Storage and transportation: It must be stored in a cool and dry environment with a temperature above 5 degrees Celsius, and the shelf life of sealed cans is above 12 months. Handle with care during storage and transportation to prevent inversion, extrusion and exposure.
8. The characteristics of main raw materials, such as polyvinyl alcohol, vinyl acetate, acrylic acid and ammonium persulfate, and the fire hazards during operation were introduced. The key points of fire prevention design in this production area were emphatically introduced, including process flow fire prevention, white latex workshop fire prevention, tank area fire prevention and automatic fire prevention facilities.
