Tabloid:Maintenance colloid of wood latex polymer emulsion
The number of hydrophilic hydroxyl groups in the xylem glue of VA molecule can be treated with polymethacrylic acid, acetylated PVA C water-soluble polyhydroxymethylacrylamide or polyvinyl acetalization. So as to improve the water resistance of PVA C emulsion. Zhang Qiuhui and other two polyvinyl alcohol (PVA) were used to modify the PVA C adhesive, and the copolymer emulsion adhesive had good water resistance. It reached and exceeded the requirements of the two kinds of product specifications of Japanese special plywood. The synthesis of PVA C emulsion is usually done with PVA as an emulsifier. Nakayama Zheno dissolves the copolymer of isobutene and anhydrous maleic anhydride with water-soluble substance after alkaline treatment. In order to form elastic membranes, a large number of plasticizers are often added, which will destroy the uniformity of the system and cause the strength of the membranes to decrease greatly. Kosaka Ren uses a heated unsaturated carboxylic acid and water-soluble macromolecule compound to prepare VA C homopolymer or copolymerization emulsion with good heat resistance for protecting colloid. This emulsion can be used as adhesive, paint, paper and fabric disposing agent. This is because when these unsaturated carboxylic acids and water-soluble macromolecule compounds are heated and dissolved in water, local esterification and amidation reactions occur, resulting in hydrophobic groups of water-soluble maintenance colloids. In addition, in the polymerization process, the copolymerization of VA C with unsaturated carboxylic acids, and VA C graft copolymerization with water-soluble polymers or water-soluble polymers with unsaturated carboxylic acids resulted in the hydrophobic part in.PVA C emulsion, thereby enhancing the water resistance of the films. As the maintenance colloid of VA C monomer or copolymer emulsion, PVA C emulsion with low temperature fluidity, film-forming property, water resistance and heat resistance is prepared. The number of hydrophilic hydroxyl groups of PVA molecule can be reduced. In addition, the water-soluble polyhydroxymethylacrylamide of polymethacrylic acid, acetylated PVA C or the condensation of PVA can be used. So as to improve the water resistance of PVA C emulsion.
