Nanometer zirconium-niobium silicone sealant and preparation method thereof

Abstract

The invention discloses a nanometer zirconium-niobium silicone sealant and a preparation method of the nanometer zirconium-niobium silicone sealant. The sealant comprises, by weight, 30-40 parts of an adhesive 107, 40-45 parts of calcium carbonate, 6-8 parts of white oil No.3, 6-8 parts of silicone oil, 0.5-0.8 part of a titanate coupling agent, 0.5-0.8 part of a titanate cross-linking agent, 0.5-1.5 parts of nanometer zirconium micro powder, 2-3 parts of nanometer niobium micro powder, 0.5-0.8 part of dibutyltin dilaurate and 0.8-1.5 parts of pigments. The preparation method includes the steps that the adhesive 107, the calcium carbonate, the white oil No.3 and the silicone oil are firstly put into a strong dispersion machine according to the parts by weight to be stirred, dissolved, fused and extruded, the titanate coupling agent, the titanate cross-linking agent, the nanometer zirconium micro powder, the nanometer niobium micro powder, the dibutyltin dilaurate and the pigments are then put into the strong dispersion machine according to the parts by weight to sufficiently react and be extruded, and finally the substances obtained in the former two steps are sufficiently fused. The nanometer zirconium-niobium silicone sealant has the advantages of being capable of achieving waterproof sealing, incapable of cracking, shrinking and falling off and long in service life.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a nano sealant and a manufacturing method. Background technique [0002] Glue plays an important role in engineering construction and other aspects. Glue is used when it comes to the adhesion of wood, bricks, metal, cement, glass, stone, plastic, aluminum products, etc. At present, there are some defects in the glue on the market, such as: 1. The waterproof and airtightness is poor, and water leakage will occur at the adhesive interface after a long time of use in a humid environment (such as a bathroom); 2. It is easy to appear in dry weather conditions. Cracking phenomenon; 3. With the increase of use time, it will gradually shrink and finally fall off, and the service life is generally within 10 years. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the defects of the prior art, and provide a nano-zirconium-niobium s...
