    • An all-purpose two-component adhesive material and a process for its production that can be used both for fastening together flexible and porous material, such as for example wood, plastics, fabric, as well as for joining stiff material such as metal, stone. In particular the process can also be carried out using as reagents compounds resulting from processes of neutralization of exhausted sulphuric acid. In large amount adhesive material can be used to make coating material, such as tiles, whereas in different concentration the adhesive material can be used as fire-retardant varnish. The adhesive material is formed by: a first component that is an aqueous solution, having concentration higher than 5% in weight, of a sulphate, chloride, nitrate, acetate of magnesium or zinc; and a second component that is a mixture of magnesium oxide MgO, metal hydroxides, calcium sulphate hemi-hydrated. The magnesium or zinc salt are chosen among MgSO 4 , MgCl 2 ; MgNO 3 ; Mg(CH 3 COO) 2 , ZnSO 4 , ZnCl 2 ; ZnNO 3 ; Zn(CH 3 COO) 2 . In the second component the metal hydroxides are chosen among Mg(OH) 2 ; Al(OH) 3 ; Fe(OH) 3 ; Ti(OH) 4 .
    • 一种通用的双组分粘合剂材料及其生产方法,其可用于将柔性和多孔材料(例如木材,塑料,织物)以及用于连接刚性材料如金属,石头 。 特别地,该方法也可以使用由中和硫酸的中和产生的试剂化合物进行。 大量的粘合材料可用于制造涂料如瓷砖,而不同浓度的粘合剂材料可用作阻燃清漆。 粘合剂材料通过以下方式形成:作为水溶液的第一成分,其浓度高于5重量%的硫酸盐,氯化物,硝酸盐,镁或锌的乙酸盐; 和第二组分,其是氧化镁MgO,金属氢氧化物,半水合的硫酸钙的混合物。 镁盐或锌盐选自MgSO 4,MgCl 2; MgNO3; Mg(CH 3 COO)2,ZnSO 4,ZnCl 2; ZnNO3; 的Zn(CH 3 COO)2等。 在第二组分中,金属氢氧化物选自Mg(OH)2; 的Al(OH)3; 的Fe(OH)3; 的Ti(OH)4。
