preparation example Construction

[0109] The preparation of the water-based coating composition of the present invention can be realized by any suitable mixing method known to those of ordinary skill in the art. For example, a waterborne coating composition can be prepared by adding the waterborne latex, filler and additives to a container, and then stirring the resulting mixture until homogeneous. Alternatively, the waterborne coating composition can be prepared by mixing some of the additional additives with the filler, and then adding the waterborne latex and the remainder of the additional additives to form a homogeneous mixture. Additional water can be added during preparation of the aqueous coating composition, if desired. Additional water should be added to the total weight of the aqueous latex.

[0110] The aqueous coating composition of the present invention can be applied by conventional methods known to those of ordinary skill in the art. For example, aqueous coating compositions can be applied by...

Embodiment 1-3

[0128] The aqueous coating compositions of Examples 1-3 were prepared as follows.

[0129] The amount listed in the following table 2, under the low-speed stirring of 350-450rpm, add deionized water and thickener Natrosol Plus 330, dispersant, wetting agent, defoamer, pH regulator to the stirrer, and stir 5-10 minutes, thus evenly. The filler is then added to the mixture and stirred at high speed at 800-1250 rpm for 20-30 minutes to form a homogeneous slurry. Finally, under medium-speed stirring at 500-700rpm, add defoamer, water-based latex, silane coupling agent, tank preservative, antifungal agent, film-forming aid, thickener TT935 and the remaining Partially deionized water until homogeneous, thereby forming an aqueous coating composition.

Embodiment 1

[0130] The water-based coating composition of embodiment 1 is used as interior wall primer; The water-based coating composition of embodiment 2 and 3 is used as interior wall finish paint.

[0131] The consumption of each component in the water-based paint composition of Examples 1-3 and the properties of the water-based paint composition and the coating formed therefrom are listed in Table 2.

[0133]

[0134] a Indicates that the VOC content is below the detection limit.

[0135] From the results in Table 2 above, it can be clearly seen that the bio-based carbon content of the water-based coating compositions of Examples 1-3 is at least 26% by weight, and can obtain the Biobased certification of the United States Department of Agriculture, and the raw materials for preparation are partially derived from renewable organisms. Basic resources, with the advantages of green environmental protectio...

Abstract

The invention relates to a water-based paint composition and a coating formed by the water-based paint composition. Bases on the total weight of the water-based paint composition, the water-based paint composition comprises, by weight, 20-70% of biologic water-based latex, 20-70% of filler and 0-10% of an additive, wherein the biologic water-based latex contains particles of an acrylic polymer containing formaldehyde degradation functional groups and at least 26wt% of biochar; due to the content of the formaldehyde degradation functional groups, the air formaldehyde purifying efficiency of thecoating formed by the water-based paint composition is 80% or above during the test of JC / T 1074-2008. The water-based paint composition little contains volatile organic compounds.

Description

technical field [0001] The invention relates to a water-based paint composition, more specifically, the invention relates to a bio-based water-based latex paint. The invention also relates to coatings obtained from the biobased aqueous coating composition. Background technique [0002] The current global economic development is facing two serious problems of fossil resource shortage and environmental pollution. [0003] On the one hand, fossil resources need to go through a long geological age to form. Due to the excessive dependence and exploitation of them by modern industry, an unprecedented energy crisis is approaching. Industrialization using fossil resources on a large scale has caused problems such as ecological degradation that threatens human existence. Serious resource and ecological crises have aroused global concern and thinking. With the depletion of petroleum resources, oil-based paints, coatings and inks not only consume petroleum resources, but also emit a...
