Paint formulation: formulation design system of waterborne paint

Core tip: water-based coatings, including water-based wood coatings, are coatings with water as dispersion medium and diluent Different from the common solvent coating, the formulation system is a more complex system In the formulation design, we should pay attention not only to the type of polymer, the properties of emulsion and dispersions, but also to rationally select various auxiliaries and take into consideration the mutual influence of each component and make reasonable matching Sometimes, some special additives should be selected according to the special requirements to finally form a suitable formula The basic components and functions of waterborne wood paint are as follows: 1 polymer emulsion or dispersion: This is the base material for film forming Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: water-based paint, including water-based wood paint, is water-based dispersion medium and diluent paint Different from the common solvent coating, the formulation system is a more complex system In the formulation design, we should pay attention not only to the type of polymer, the properties of emulsion and dispersions, but also to rationally select various auxiliaries and take into consideration the mutual influence of each component and make reasonable matching Sometimes, some special additives should be selected according to the special requirements to finally form a suitable formula The basic composition and function of waterborne wood lacquer are as follows: 1 polymer emulsion or dispersion: This is the base material of film forming, and determines the main function of the film 2 film forming AIDS: after water evaporates, the emulsion or dispersion particles form a uniform and dense film and improve the film-forming property at low temperature 3 Antifoaming agent and defoamer: inhibit the bubbles generated in the paint liquid during the production process, and make the generated bubbles escape from the liquid surface and break the bubbles 4 Wetting leveling agent: improve the wettability of the paint liquid to the substrate, improve the leveling, and increase the adhesion of the paint film to the substrate 5 Rheological additives: provide good fluidity and leveling for paint materials, and reduce the defects in the coating process 6 Surface control additive: improve the performance of the coating 7 Matting agent: adjust and control the glossiness of waterborne wood paint coating 8 Preservative: prevent the paint from mildew during storage 9 PH regulator: adjust the pH value of paint liquid to make it stable 10 Colorants and fillers 11 Special additives In addition, a small amount of deionized water is often added to paint formulation design to make paint 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,
