Problems solved by technology

[0002] Traditional architectural coatings are no longer suitable for international environmental protection requirements due to their toxic substances and poor toughness.
In recent years, extensive research and exploration have been carried out on new coatings with superior performance at home and abroad, among which toughened environmental protection coatings are an important research direction, but in general, the development of toughened environmental protection coatings is still in the initial stage, and the performance indicators Not enough to meet the needs, as far as exterior wall coatings are concerned, the performance is not good

Abstract

The invention discloses a waterborne acrylic coating for an outer wall. The waterborne acrylic coating is prepared from the following raw materials in parts by weight: 50 to 70 parts of acrylic esteremulsion, 10 to 16 parts of waterborne epoxy resin, 8 to 10 parts of ethylene glycol, 25 to 35 parts of bamboo powder fibers, 10 to 16 parts of coal gangue, 10 to 18 parts of silicon carbide, 14 to 22parts of vermiculite powder, 10 to 18 parts of carbon nanotube, 3 to 5 parts of filming assistant, 1 to 2 parts of flatting agent, 1 to 2 parts of wetting dispersant, 1 to 2 parts of defoamer, 2 to 4parts of mildew-proof agent, and 80 to 100 parts of water. The waterborne acrylic coating has the advantages that the toughness is good; the waterborne acrylic coating is suitable for various environments and temperatures; the defects of warp of surface skin, falling and the like due to poor toughness can be overcome; the adsorbing property is good; the sticking strength with the wall is high; the waterproof property is excellent; the release of VOC (voltaic organic compound) is avoided, the environment-friendly effect is realized, the health of body and mind is guaranteed, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based acrylic coating for exterior walls. Background technique [0002] Traditional architectural coatings are no longer suitable for international environmental protection requirements due to their toxic substances and poor toughness. In recent years, extensive research and exploration have been carried out on new coatings with superior performance at home and abroad, among which toughened environmental protection coatings are an important research direction, but in general, the development of toughened environmental protection coatings is still in the initial stage, and the performance indicators Can not meet the needs, as far as the exterior wall coating is concerned, the performance is not good. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a water-based acrylic paint for exterior wa...
