Coating knowledge: formula of common interior wall emulsion paint

Core tip: latex paint is a kind of waterborne coating made of synthetic resin emulsion, which is made up of pigments, fillers and various auxiliaries Since it is made of so many materials, there must be its formula Here is the common formula of interior wall emulsion paint recommended by experts I hope it can help people in need Formula table of common interior wall latex paint: No formula composition ratio (kg) ratio (liter) 1 deionized water 100; 2 bactericide 1; 3 dispersant 4; 4 pH regulator 2; 5 ester alcohol 12 5; 6 defoamer 1.5; 7 preservative 4; 8 hydroxyethyl Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coatings home: latex paint is a kind of waterborne coating made of synthetic resin emulsion, which is made up of pigments, fillers and various auxiliaries Since it is made of so many materials, there must be its formula Here is the common formula of interior wall emulsion paint recommended by experts I hope it can help people in need Formula table of common interior wall latex paint: No formula composition ratio (kg) ratio (liter) 1 deionized water 100; 2 bactericide 1; 3 dispersant 4; 4 pH regulator 2; 5 ester alcohol 12 5; 6 defoamer 1.5; 7 preservative 4; 8 hydroxyethyl cellulose 5 8; 9 need to pre dissolve 9 glycol 25; 10 deionized water 100 fully mix evenly; 11 titanium dioxide 250; 12 anhydrous aluminum silicate 200 high speed dispersing 15MIN; 13 defoamer 1.514 deionized water 90; 15 styrene acrylic emulsion 230 1、 The selection of dispersant: 1 According to the different thickener system, choose different dispersant types 2 When the thickening system is ASE type and hase type thickeners, I recommend using CPA, which has excellent thermal storage stability; when using Huer type thickeners, we recommend using kPa; our experiments show that the coating produced by using CPA and kPa will not have adverse phenomena in the storage process due to the increase of the amount of dispersant 3 We use CPA with MC35 to thicken the formula of interior wall mercerizing, and use kPa with pu40 to thicken the formula of interior wall mercerizing The effect is good 2、 Titanium dioxide and lithopone (lithopone) are the main pigments used in the selection of pigments and fillers These two kinds of white pigments are harmless to human body, and most of the color pigments are harmless to human body The commonly used fillers are calcium carbonate (white powder), talcum powder, kaolin (porcelain clay), barium sulfate (barite powder), wollastonite powder, etc., which are natural mineral raw materials, harmless to human body 3、 In order to prevent the emulsion paint from settling in the process of storage and to avoid falling when painting the vertical surface, the thickener is usually cellulose ether Four The choice of emulsion is the most important raw material that affects the performance of latex paint The appearance is similar to milk It is made of some petrochemical raw materials, such as vinyl acetate, acrylate, styrene, etc., through polymerization chemical reaction in water Due to the different raw materials and processes, the emulsion produced is also different in performance Its main function is to bond, resist water, alkali and resist light aging The production process of common emulsion knee is as follows: 1 Mix water (deionized water is preferred, and groundwater cannot be used) with a variety of additives, including dispersant, wetting agent, leveling agent, anti-corrosion and anti mildew agent, film-forming assistant, buffer, defoamer, antirust agent and whitening agent, and mix them at a low speed; 2, add white pigments and fillers (solid powder), hydroxyethyl cellulose (789) aqueous solution to disperse at high speed, and make white slurry when necessary 3, add batches of white pulp slowly into the emulsion, and the white slurry added before the batch can be added to the latter batch of white slurry after stirring at low speed, and then keep stirring at low speed to obtain the first coating 4 Use thickener to adjust the viscosity of the initial coating, use color paste to mix the color and depth of the initial coating, or add some defoamer to be the finished product of emulsion paint After filtering, weighing, packaging and inspection, it can be put into storage or put on the market Note: the above information is for reference only [focus on WeChat official account "paint net";
