Embodiment 1
[0031] The water-based crack primer is made by mixing the following raw materials according to weight percentage: 80% water-based cationic acrylic emulsion, 8.2% water, 3% dipropylene glycol butyl ether, 3% rheological agent RM-2020, 0.5% defoamer DF210, 0.3% wetting agent TEGO 245 and 5% special effect color paste.
[0032] The water-based cationic acrylic emulsion used is INTERPOLYMER 6301, with a solid content of 35% by weight, a pH value of 6, and a Tg≤10°C.
[0033] First weigh the water-based cationic acrylic emulsion and add it to the paint making tank, add water and mix under stirring, then add dipropylene glycol butyl ether, RM-2020, DF210, TEGO 245 and special effect color paste while stirring at a slow speed. , and then dispersed at a medium speed for 10 minutes to obtain a water-based crack primer.
[0034] The resulting primer test results are as follows:
[0035] Solid content: 29-30%; appearance: milky white transparent product.
[0036] The water-based crack...

Abstract
The invention discloses a water-based crack lacquer as well as a preparation method and a construction method thereof. The water-based crack lacquer comprises a water-based crack priming lacquer and a water-based crack finishing lacquer, wherein the water-based crack priming lacquer comprises the following raw materials: 75-90% of a water-based cationic acrylic or polyurethane emulsion, 5-20% of water, 2-5% of an alcohol ether cosolvent, 1-3% of a rheological agent and 0.5-1% of a defoaming agent; the water-based crack finishing lacquer comprises the following raw materials: 75-90% of a water-based anionic acrylic or polyurethane emulsion, 3-20% of water, 2-9% of an alcohol ether cosolvent, 1-3% of a rheological agent and 0.5-1% of a defoaming agent. According to the water-based crack lacquer, the cationic priming lacquer and the anionic finishing lacquer are used; the emulsification mechanisms of the priming lacquer and the finishing lacquer are different; after the finishing lacquer permeates through the priming lacquer, the cations during the nucleation contact with the anions, and the cations and the anions interact with each other to ensure that the finishing lacquer cannot form a continuous lacquer film so as to show the color of the base material. The water-based crack lacquer has the characteristics of being environment-friendly, tasteless, basically free of environment influence during construction, energy-saving and emission-reducing.
Description
technical field [0001] The invention relates to a preparation method of cracked paint, in particular to a water-based cracked paint and its preparation method and construction method. Background technique [0002] In recent years, with the development of the national economy and the improvement of living standards, the style of architectural decoration is changing with each passing day. There are more and more varieties of materials used in decoration. Crackle paint has also quietly emerged in the decoration industry. The surface plays a protective and decorative role, and increases the added value of the product. Therefore, as a special decorative effect, crackle paint is widely used in many antique finishes. [0003] Crackle paint is prepared by grinding nitrocellulose, pigments, extender pigments, organic solvents, auxiliary agents, etc. to form nitro crackle paints of various colors, and it is precisely this that crackle paints also have some basic characteristics of ni...
