2.3.2 lotion PVC
Lotion PVC is a white PVC with particle size of 0.1-1 μ M. Powder loose paste resin. It is tasteless, non-toxic and stable to acids, alkalis and salts under normal temperature. It can be mixed with plasticizer and other additives to form a paste with good plasticizing property. Under normal temperature, the thickened viscosity of the mixed paste shall not exceed 20% after 24h, without precipitation; At high cut
The paste has low viscosity and good coating performance at variable rate, which is suitable for high-speed coating.
① Artificial leather and wallpaper are produced by coating and scraping method.
② Dipping production is to dip the male mold into the plasticizing paste at a certain temperature, put it out after a certain period of time, and heat the excess paste after dripping, so that the paste layer gel attached to the male mold is plasticized, and then demoulded into products. The dip coating method can be used to produce plastic products in two ways: intermittent method and continuous method. The intermittent method can be used to produce industrial gloves, flexible pipes, cable heads and tool handles; The continuous production method can be used for coating production of paper, fabric, etc.
③ The plastic lining method is to pour the paste into the mold, pour the mold, melt the thin layer of paste left on the inner wall of the plasticizing mold, cool down, and then open the mold to get the products. When this method is used for production, if a certain proportion of foaming agent is added into the paste, foaming products can also be made.
In addition, certain proportion of other materials can also be added into lotion PVC resin to make sintered boards and rigid foams, or lotion can be directly used as paper polish, coating and adhesive.
Lotion PVC resin is mainly used to make paste resin in plastic product industry. For example, it is used to make breathable foam artificial leather, ordinary artificial leather, floor leather, foam plastic, plastic lining products, toys, glove outer film, metal surface acid proof outer film, industrial cloth, insulation materials, spraying latex, packaging materials, various beverage bottles and various gaskets for bottle caps; It can also be used to make some extruded products.
Lotion method polyvinyl chloride (PVC) can also be called polyvinyl chloride or paste polyvinyl chloride resin. See Table 2-69 for the technical indicators specified in the national standard GB 15592-1995 of PVC resin for paste.

2.3.2.2 Forming method and use
Add 30%~50% plasticizer and some other additives (according to the requirements of product performance) into lotion PVC resin, mix them evenly and prepare viscous flow plastisol. After removing the air, plastic products can be molded by scraping, dipping, plastic lining, rotational molding and pouring.① Artificial leather and wallpaper are produced by coating and scraping method.
