Application

Polyvinyl alcohol-Stabilizer for emulsion, protective colloids.

The raw materials of PVAc mainly consist of dibutyl phthalate, octanol, vinyl acetate, polyvinyl alcohol, and ammonium persulfate. The properties and functions of each raw material are as follows: 1. dibutyl phthalate: used as a plasticizer in PVAc, this raw material is a plasticizer in the production of plastics, synthetic rubber, synthetic leather, etc. It is also a solvent and curing agent for spices, a colorless liquid, insoluble in water, and soluble in organic solvents such as ethanol and ether. 2. Octanol: Used as a solvent in PVAc, it has a special odor and is soluble in organic solvents such as water, ethanol, and ether. 3. Vinyl acetate: Used as an adhesive in PVAc, abbreviated as vinyl acetate, it is a colorless flammable liquid with a strong aroma. Its vapor is irritating to the eyes, insoluble in water, and soluble in most organic solvents. It is used to make vinyl esters and synthetic fibers, as well as in rubber, paint, adhesives, and other industries. 4. Polyvinyl alcohol: used as a bonding agent in PVAc, this raw material is a polymer compound formed by saponification of polyvinyl acetate, white or milky yellow powder, with thermoplastic properties. 5. Ammonium persulfate: used as a polymerization initiator in PVAc, colorless monoclinic crystal, sometimes slightly greenish, soluble in water, decomposes when heated, has strong oxidizing properties, and is used as a bleaching agent, oxidant, deodorizer, etc. Characteristics of PVAc: White latex is a dispersant made of water, which is safe, non-toxic, non flammable, and easy to clean. It solidifies at room temperature and has good adhesion to wood, paper, and fabrics. The bonding strength is high, and the cured adhesive layer is colorless and transparent, with good toughness and no pollution to the bonded material; The lotion has good stability, and the storage period can reach more than half a year; PVAc is widely used in printing, binding, and furniture manufacturing, as an adhesive for paper, wood, cloth, leather, ceramics, etc. It can also be used as a modifier for adhesives such as phenolic resin and urea formaldehyde resin, and is used to manufacture polyvinyl acetate latex paint, etc; PVAc is a polymer compound polymerized from polyvinyl alcohol and formaldehyde as a modifier, which improves the water resistance and freeze thaw resistance of lotion and expands the application range of lotion.
