[0027] In parts by weight, add 60 parts of nano-silica, 20 parts of nano-alumina, 8 parts of nano-zirconia, and 10 parts of nano-hydroxyapatite into the mixer, and stir and mix for 2 hours to obtain a nano-inorganic powder; Then in parts by weight, successively take 100 parts of hydroxyl-terminated polydimethylsiloxane, 100 parts of carboxy-terminated polydimethylsiloxane, 10 parts of sodium stearate, 20 parts of dodecylbenzenesulfonate Na2SO4, 4 parts of triethanolamine, 180 parts of deionized water, 3 parts of sodium carboxymethyl cellulose, 100 parts of nano-inorganic powder, first deionized water, sodium stearate, sodium dodecylbenzenesulfonate, Add triethanolamine, sodium carboxymethylcellulose and nano-inorganic powder into the reaction kettle according to the formula, stir and mix at a constant temperature for 45 minutes at a temperature of 60°C and a speed of 600r / min, and then add hydroxyl-terminated polydimethylsiloxane Alkanes, carboxyl-terminated polydimethylsiloxa...

example 2

[0029]In parts by weight, 70 parts of tetraethyl orthosilicate, 130 parts of absolute ethanol, 25 parts of citric acid solution with a concentration of 0.1mol / L, and 15 parts of silane coupling agent KH-560 are taken successively. First, dehydrated alcohol, Pour the citric acid solution and the silane coupling agent KH-560 into the reaction kettle, stir at a constant temperature for 45min at a temperature of 63°C and a rotation speed of 400r / min, then add ethyl orthosilicate dropwise into the reaction kettle, and wait for the dropwise addition After completion, continue to stir and hydrolyze for 4 hours at a constant temperature to obtain a hydrolyzate, then pour the obtained hydrolyzate into an evaporating dish, heat and evaporate to obtain a mixed gel, and wash the obtained mixed gel with deionized water until the washing liquid is neutral. The washed mixed gel was transferred to an oven, and dried to a constant weight at a temperature of 108°C to obtain a dried gel, and then...

Abstract

The invention discloses nano inorganic powder modified organic silicon waterproof paint and belongs to the technical field of building waterproofing. The nano inorganic powder modified organic silicon waterproof paint disclosed by the invention is prepared from the following raw materials in parts by weight: 200 to 300 parts of an oligomer siloxane base material, 10 to 30 parts of an emulsifier, 20 to 60 parts of a stabilizer, 4 to 6 parts of a curing agent, 180 to 200 parts of a diluting agent, 3 to 6 parts of a thickener and 100 to 150 parts of nano inorganic powder; the nano inorganic powder is prepared from the following raw materials in parts by weight through mixing: 60 to 80 parts of nano silicon dioxide, 20 to 30 parts of nano aluminum oxide, 8 to 10 parts of nano zirconium oxide and 10 to 15 parts of nano hydroxyapatite. The nano inorganic powder modified organic silicon waterproof paint disclosed by the invention has the beneficial effects that the nano inorganic powder modified organic silicon waterproof paint has a relatively excellent weather-resisting performance and a long service life; a hydrophobic bionic structure formed by added inorganic nanoparticles does not hinder the permeation of water vapor in a substrate.

Description

technical field [0001] The invention relates to a nano inorganic powder modified organic silicon waterproof coating, which belongs to the technical field of building waterproofing. Background technique [0002] Building waterproof coating has the characteristics of simple construction and strong adaptability to complex structures, and is widely used in building construction. Waterproof coatings are mainly used for waterproofing, moisture-proofing and anti-seepage of some structural parts of buildings that may be eroded by water. Therefore, there are certain requirements for high-temperature resistance and anti-corrosion performance of waterproof coatings. Existing architectural waterproof coatings mainly include polyurethane waterproof coatings, polymer cement waterproof coatings, and silicone waterproof coatings, among which silicone waterproof coatings are widely used. [0003] Silicone waterproof coatings are divided into water-based environmentally friendly waterproof c...
