Method of preparing hardening compositions
专利汇可以提供Method of preparing hardening compositions专利检索，专利查询，专利分析的服务。并且Hardenable compositions are made by mixing a vinyl ester and water glass. Vinyl acetate is the specified ester. Additives which together with the reaction mixture or by themselves form condensation or polymerization products, e.g. vinyl compounds, allyl compounds, styrene, acrylic acid, amino acids, amines, aldehydes, ketones and halogenated organic compounds such as ethylene dichloride, chlorinated paraffins and oils, epichlorohydrin and polymerizable esters may also be added. Siloxanes, which during the reaction polymerize to form siliconates may also be added. Fillers, e.g. wood meal, cellulose, sand, marl, clay, chalk, coal, lignite, pigments and precipitated metal silicates may be added to the reaction mixture at any stage. In the examples: (1) potassium water glass and vinyl acetate are mixed and allowed to stand to form a hard mass or heated above 100 DEG C. to form a porous mass; (2) sodium water glass, vinyl acetate and aluminium butyl are mixed and either allowed to gelatinize or heated; (3) as in Example (2) with the addition of marl; (4) potassium water glass is mixed with a partially polymerized ester of vinyl alcohol with a higher fatty acid and a pigment, the mass obtained being used as a paint; (5) vinyl acetate is mixed with butane dichloride and sodium water glass, an alkyl aryl sulphonate and fuel oil are then added and the reaction mixture allowed to gelatinize to a resilient composition suitable for the manufacture of moulded articles; (6) polyvinyl chloride, polyvinyl acetate is polyethylene is dissolved in vinyl acetate, if desired, together with methyl butylketene, cyclohexanone or cyclohexanol, and the mixture mixed with sodium water glass. The products of the invention may be used for moulded articles and in coatings and paints.，下面是Method of preparing hardening compositions专利的具体信息内容。
