preparation example Construction

[0120] The preparation of the interior wall coating composition of the present invention can be realized by any suitable mixing method known to those skilled in the art. For example an interior paint composition may be prepared by adding the aqueous emulsion, filler and additional additives, if present, to a container and stirring the resulting mixture until homogeneous. Alternatively, the interior paint composition can be prepared by mixing some of the additional additives with the filler and then adding the aqueous emulsion and the remainder of the additional additives to form a homogeneous mixture. Additional water can be added during preparation of the interior paint composition, if desired. The additional amount of water should be added to the total weight of the aqueous emulsion.

[0121] The interior paint composition of the present invention can be applied by conventional methods known to those of ordinary skill in the art. For example, the interior paint composition...

Embodiment 1-3 and comparative example A

[0139] The interior wall coating compositions of Examples 1-3 and Comparative Example A were prepared as follows.

[0140] Under low-speed stirring at 350-450rpm / min, add 200g of deionized water and a certain amount of thickener HMHECPlus330, dispersant N40, defoamer SN154, anhydrous sodium carbonate to the stirrer, and stir for 5-10 minutes, thus uniform. Then add fillers HS801A, GF117 and Zeeospheres to the mixture TM (in embodiment 1-3), and with 80-1250rpm / minute high-speed stirring 20-30 minutes, thereby form homogeneous slurry. Finally, add defoamer 122NS, Celvolit CP1608 emulsion, BIT20 bactericide, PW40 antifungal agent, thickener TT935 and the remaining part of deionized water to the homogeneous slurry under medium speed stirring at 500-700rpm / min until uniform , thereby forming an interior wall coating composition. The amount of each component in the interior wall paint composition of Examples 1-3 and Comparative Example A is listed in Table 2.

Abstract

The invention relates to an aqueous inner wall paint composition. Based on the total weight of the paint composition, the paint composition comprises the following components: 30-80wt% of aqueous emulsion of vinylacetate-ehtylene copolymer, 20-70wt% of filling material and 0-10wt% of additive, wherein the filling material comprises 15-40wt% of ceramic microsphere based on the total weight of the filling material. The aqueous inner wall paint composition has a low-content or even no volatile organic compound (VOC) and can form a coating capable of improving soiling resistance and scrubbing resistance.

Description

technical field [0001] The present invention relates to an aqueous interior wall coating composition, and more particularly, to an aqueous interior wall coating composition that has a low, or even zero, VOC (volatile organic compound) content and will form a stain-resistant, scrub-resistant coating . Furthermore, the invention also relates to coatings obtainable from the aforementioned aqueous interior paint compositions. Background technique [0002] At present, since people pay more and more attention to health and environmental issues, interior wall coating compositions used indoors are required to have better environmental friendliness than before. In particular, interior paint compositions are required to have low VOC content. However, the resin components used in some conventional waterborne interior paint compositions may cause non-negligible VOC emissions. In addition, traditional interior wall coating compositions have relatively poor film-forming properties, so ...
