Coating process: production process of inorganic potassium silicate exterior wall coating

Core tips: 1 Reference formula of inorganic potassium silicate exterior wall coating: Raw material Single component potassium silicate 10040 component potassium silicate 20 25- pigment and filler 35~48100 to 160 dispersant (anionic) 0.3 to 0.60.3 to 1.35 defoamer 0.2 to 0.4 defoamer thickener, 3~5 film builder, 1 to 3-, its auxiliary quantity, curing agent (condensed aluminum phosphate) -6.0 ~ 8 water 10.015.0 ~ 1 potassium phosphate external wall coating There are two materials Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Coatings home news: 1, inorganic potassium silicate exterior wall paint reference formula: raw material consumption (mass fraction) /%, single component potassium silicate type potassium silicate 20~25 potassium silicate 10040 styrene acrylic emulsion 20~25 - pigment and filler 35~48100 ~ 160 dispersant (anionic) 0.3 ~ 0.6 0.3 ~ 1.35 defoamer 0.2 ~ 0.4 foam volume thickening agent, appropriate amount of film forming agent adjuvant - other auxiliaries - commonly used amount of curing agent (condensed aluminum phosphate) - 6 ~ 8 water 10 15 ~ 25 potassium phosphate external wall coating has two kinds: one is a composite coating with a small amount of synthetic resin emulsion, and the other is a two component coating with curing agent in construction 2 Coating production process: ① put the potassium silicate solution into the mixing tank, add water and mix evenly ② The dispersant is put into the mixing tank, then various pigments and fillers are put into the mixing tank After the mixing is even, the film-forming assistant and some defoamers are put into the mixing tank The slurry is obtained by stirring at high speed (800-1000r / min) for 0.5h Grind the slurry to a fineness less than 60 μ m, and then transfer the milled mixture slurry to the mixing tank (3) at low speed (300 ~ 500r/min) stirring state, SBR emulsion is added slowly into the stirring tank, and then added to stir 20min to make it uniform Depending on the amount of foam, add proper amount of defoamer, stirring and defoaming ④ If it is necessary to configure the color coating, the type and quantity of the added color paste can be determined according to the test of the color card, and then the color can be uniformly mixed to the desired color The production process of two-component potassium silicate exterior wall coating is similar to the single component coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
