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] The preparation of embodiment 1 water-based high plump 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 mix well, then add C3 to the bucket and mix well, then add C4 to the bucket to dilute and mix well. After fully mixing and stirring in the large bucket, pour in a small barrel, slowly add it into the dispersion tank in a linear shape, and disperse at 1000r / min for 15 minutes until the scraper has no oil shrinkage;

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

[0079] Among them, each component and its dosage are:

[0080] A1: acrylic resin 70kg;

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

[0082] B1: fungicide 0.1kg;

...

Embodiment 2

[0095] The preparation of embodiment 2 water-based high plump 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 mix well, then add C3 to the bucket and mix well, then add C4 to the bucket to dilute and mix well. After fully mixing and stirring in the large bucket, pour in a small barrel, slowly add it into the dispersion tank in a linear shape, and disperse at 1200r / min for 15 minutes until the scraper has no oil shrinkage;

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

[0099] Among them, each component and its dosage are:

[0100] A1: acrylic resin 75kg;

[0101] A2: 10kg of water-based polyurethane resin;

[0102] B1: fungicide 0.2kg;

[0103] B2: wat...

Embodiment 3

[0115] Example 3 Water-based high plump clear primer

[0116] The water-based high plump clear primer prepared in Example 1 was mixed with water in a weight ratio of 100:10.

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 plump 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, safeguard 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 passed the " The Environmental Protection Law Amendment, the new law known as "the most severe in history", came into effect on January 1, 2015. With the improvement of people's quality of life and high attention to health, the future home decoration and furniture coatings market must be the world of water-based paint. The promotion of water-based wood coatings is very beneficial to the rational use of resources and the improvement of environmental...
