A kind of water-based beautifying agent and preparation method thereof

Abstract

The invention relates to a water-based crack sealer and a preparation method thereof. The water-based crack sealer comprises the following components in parts by weight: 26-50 parts of polymer emulsion, 1-10 parts of pigment, 10-20 parts of crack-resistant aid, 20-40 parts of vapor-phase silicon dioxide, 0.1-0.7 part of wetting and dispersing agent, 0.1-0.5 part of defoaming agent, 0.6-1.5 parts of antifreezing agent, 0.5-0.9 part of film forming aid, 0.2-0.4 part of pH value regulator and 0.1-0.5 part of preservative. The water-based crack sealer has the advantages of high solid content and moderate colloide thickness, and the formed adhesive film has small shrinkage and favorable filling effects; by using the special crack-resistant material, the water-based crack sealer can not easily become aged or crack in the long-time use process; the water-based crack sealer has high tensile strength and favorable toughness, and thus, can effectively resist rupture deformation caused by displacement; and the water-based crack sealer also has the advantages of no mildewing, high safety, environment friendliness, bright color and high glossiness.

Description

technical field [0001] The invention relates to a beautifying agent, specifically a water-based, high-solid-content, anti-aging and cracking beautifying agent, and also relates to a preparation method of the above-mentioned water-based beautifying agent. Background technique [0002] With the development of building decoration materials, the application of ceramic tiles, stone materials, mosaics, wood lines and other materials is becoming more and more common. In the decoration process, there will inevitably be gaps when the materials are spliced. The traditional crafts generally choose pointing agents, caulking agents or white cement for filling. Contaminated and yellowed, blackened, moldy, mold breeding, affecting the furniture environment. Moreover, the traditional caulking agent is monotonous in color and complex in construction technology, which has a certain adverse effect on the decoration of the gap. Beautifying agent is a new type of adhesive for gap decoration th...

Problems solved by technology

Patent 2015107576740 discloses a high-solid-content one-component beautifying agent and its preparation method, which has a high solid content and can effectively solve the problem of serious shrinkage after construction and cannot be molded at one time. However, due to the use of a large amount of fumed silica, the preparation The adhesive beautifying agent has a large consistency, which is not conducive to construction, and the effect of anti-cracking is not mentioned; an environmentally friendly beautifying agent and its preparation method disclosed in patent 2015102587626 have the characteristics of luster, rich colors, natural and fine, etc., but it does not mention And related application effect data, especially the cracking resistance after a period of use can not be judged; patent 201410271033X discloses a ceramic tile gap beautifying agent, the solid content is not high, easy to shrink; patent 2015108445135 discloses a silver The production formula of ion beautifying agent has the characteristics of wide construction range, strong adhesion, waterproof, and weathering resistance. The preparation method does not disclose the specific process parameters and effects of the beauty joint agent
