<p>The invention relates to adhesives manufacturing. These adhesives are used in household and industry for adhering various materials (concrete, ceramics, different coatings, etc) exploited under temperatures +50°C to -20°C and under elevated humidity. Adhesive composition represents the product of interaction between potassium silicate aqueous solution (density of 1,3 to 1,37 g/cm3, molar ratio SiO2/K2O of 3, 4 to 3, 7), anhydrous lithium hydroxide mixed with di- or triatomic alcohol, vollastonite (particle size of 150 µm and smaller, length to diameter ratio 5-3:1), talc (particle size of 10 to 20 µm mainly) and inorganic pigment. Adhesive composition is prepared by given consecutive mixture of components. Adhesive composition has enhanced activity (storage stability) and water resistance. It also has improved strangth of adhesion junction while adhering various materials; it is non-toxic and pollution-free.</p> |
