Water-based paint formulation, composition analysis

Coatings refers to materials applied to the surface of objects and can form a tough protective film, architectural coatings are an important category of coatings, in China, generally used in building walls, external walls, roofs, floors, toilet coatings called architectural coatings.
building coatings mainly have film-forming agents, generally used synthetic resins, solvents, solvents, mainly alcohols, ketones, esters, surfactants, plasticizers, drying agents, leveling agents, anti-cortical agents and other additives and fillers, if the special coating also contains other fillers and additives with special properties.
architectural coatings are divided into interior and exterior paint. Inner wall coatings include powders and liquid interior wall coatings, which are made up of water, pigments, lotions, fillers and various additives that are virtually non-toxic. As latex paint, it is mainly glycol in film-forming agents and organic mercury in mold inhibitors that can be toxic.
bedroom interior wall commonly used coatings can be divided into the following categories:
the first category is low-grade water-soluble paint, is polyethylene alcohol dissolved in water, and then add pigments and other additives. This kind of coating has the advantages of cheap, non-toxic, odorless, convenient construction and so on. Because its film is water-soluble, so scrubbing with a damp cloth always leave some traces, durability is not good, easy yellowing color change, but its price is cheap, construction is also very convenient.
The second category is latex paint, it is a water-based medium, acrylic, styrene-acrylic copolymers, ethylene acetate polymer aqueous solution for film-forming substances, added a variety of auxiliary ingredients made, its film is insoluble in water, coating water resistance and weather resistance than the previous class greatly improved, wet scrubbing without traces, and flat light, high light and other decorative types.
The third category is the current very popular colorful paint, the coating film-forming material is nitroculose, in the form of water-coated oil scattered in the water phase, a spray can form a variety of color patterns.
The fourth category, also known as liquid wallpaper, liquid wallpaper, is currently a popular trend of large interior wall decorative coatings, environmental protection, diverse effects, color arbitrary modulation, and can be arbitrarily ordered effect, compared to the fourth category has super friction resistance, anti-fouling performance, and process with special mold construction convenience, loved by consumers and designers.
category, new mud powder coatings, including diatom mud, seaweed mud, etc., are currently relatively environmentally friendly coatings. Mud paint, process with special mold construction, by consumers and designers love.
:Through the separation and purification of the original product, reverse analysis and the map library standard map ratio qualitative analysis, the purchase of standard samples for quantitative analysis. Recommended possible production processes, raw material brand, for molecular weight, viscosity of these indicators will be labeled, convenient for enterprises to choose raw materials. Post-technical services: technical guidance, method development, customers can go to the laboratory and technicians on-site communication and discussion.
: through the reverse analysis of samples, obtain the basic formula, in the market to buy raw materials for sample configuration, adjustment process, small samples to customers to try, until customer satisfaction, to achieve small trial success;
: comparing peer products, optimizing formulation materials, adjusting raw materials and reducing costs under the premise of constant performance;
: Through failure analysis to diagnose the cause of functional disorders, give solutions.
