Problems solved by technology

The first two are solvent-based paints, which do not meet the national requirements of advocating green and environmental protection. At present, there are mixed water-based high-volume clear primers on the market. After air-mixed painting, there are more bubbles, which makes the paint film whitish and not clear. Defects such as transparency and poor fullness

Embodiment 1

[0075] Embodiment 1 The preparation of water-based high-volume clear primer

[0076] 1. Put A1 and A2 into the dispersing tank in turn, disperse at 600r / min for 5 minutes, then put in B1, B2 and B3, and stir evenly;

[0077] 2. In the container bucket, first use C1 to dilute C2 and stir well, then add C3 into the bucket and mix well, then add C4 into the bucket and mix well, mix well in the large bucket, then pour into the small Add the bucket into the dispersing cylinder slowly in a linear shape, and disperse at 1000r / min for 15min until the scraper has no oil shrinkage;

[0078] 3) Weigh D1 accurately, add half of the added amount first, stir well at a medium speed, and then add the remaining D1 and D2. A water-based high-volume clear primer with a viscosity of 85-90KU / 25°C is obtained.

[0079] Wherein, each component and consumption thereof are:

[0080] A1: Acrylic resin 70kg;

[0081] A2: 5kg of water-based polyurethane resin;

[0082] B1: 0.1kg fungicide;

[0083]...

Embodiment 2

[0095] Embodiment 2 Preparation of water-based high-volume clear primer

[0096] 1. Put A1 and A2 into the dispersing tank in turn, disperse at 800r / min for 5 minutes, then put in B1, B2 and B3, and stir evenly;

[0097] 2. In the container bucket, first use C1 to dilute C2 and stir well, then add C3 into the bucket and mix well, then add C4 into the bucket and mix well, mix well in the large bucket, then pour into the small Add the bucket into the dispersing cylinder slowly in a linear shape, and disperse at 1200r / min for 15min until the scraper has no oil shrinkage;

[0098] 3) Weigh D1 accurately, add half of the added amount first, stir well at a medium speed, and then add D1 and D2. A water-based high-volume clear primer with a viscosity of 85-90KU / 25°C is obtained.

[0099] Wherein, each component and consumption thereof are:

[0100] A1: Acrylic resin 75kg;

[0101] A2: Waterborne polyurethane resin 10kg;

[0102] B1: 0.2kg fungicide;

[0103] B2: 2kg of water;

Abstract

The invention provides a water-based high-fullness clear primer. The preparation method of the water-based high-fullness clear primer comprises the following steps: firstly, sequentially putting A1 and A2 into a dispersing cylinder, putting B1, B2 and B3 into the dispersing cylinder after the A1 and the A2 are dispersed, and then uniformly stirring; secondly, sequentially adding C1, C2, C3 and C4 into another container while stirring, after intensive stirring, slowly adding the C1, C2, C3 and C4 into the dispersing cylinder in a linear way, performing dispersing till no condensed oil exists on a scrapper; thirdly, firstly adding 1 / 2D1, then adding 1 / 2D1 and D2 after the 1 / 2D1 is uniformly stirred at an intermediate speed, and obtaining the water-based high-fullness clear primer, wherein A1 is 70 to 75 parts of self-cross-linking acrylic resin emulsion; A2 is 5 to 10 parts of water-based polyurethane resin emulsion; B1 is 0.1 to 0.2 parts of sterilizing agent; B2 is 2 to 6 parts of water; B3 is 1 to 2 parts of propylene glycol; C1 is 3 to 5 parts of coalescing agent; C2 is 2 to 3 parts of defoaming agent; C3 is 0.2 to 0.6 parts of flatting agent; C4 is 1 to 8 parts of water, D1 is 0.4 to 0.6 parts of thickening agent; D2 is 0.6 to 4.3 parts of water.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based high-volume clear primer and a preparation method thereof. Background technique [0002] In order to protect and improve the environment, prevent and control pollution and other public hazards, protect public health, promote the construction of ecological civilization, and promote sustainable economic and social development, on April 24, 2014, the Eighth Session of the Standing Committee of the Twelfth National People's Congress voted and passed the " The Amendment to the Environmental Protection Law, known as the "most stringent" new law, came into effect on January 1, 2015. With the improvement of people's living standards and high attention to health, the future home decoration and furniture coating market must be dominated by water-based paint. The promotion of water-based wood coatings is very beneficial to the rational use of resources and the improvement of environme...
