Abstract

The invention discloses an antibacterial negative ion anti-aging coating and a preparation method thereof, and relates to the field of building materials. The coating consists of water, pH regulator, hydroxyethyl cellulose, dispersant, de-foaming agent, pigment filler, anti-settling agent, anti-aging agent, bactericide, dry film antifogging agent, negative ion powder, film forming aid, water-based emulsion, rheology modifier and thickening agent. The preparation method comprises the following steps of: sequentially adding the dispersant, a wetting agent, the pH regulator, the de-foaming agent and the hydroxyethyl cellulose solution into a certain quantity of water at the low revolving speed of less than 600 revolutions per minute, and fully stirring and dispersing; and adding the bactericide, the anti-aging agent, the pigment filler and the anti-settling agent according to the sequence as required by the formula, performing high-speed dispersion at the revolving speed of more than 1,200 revolutions per minute by using a high-speed dispersion machine, adding the emulsion, the de-foaming agent, the thickening agent and the rheology modifier, finally adding the thickening agent to regulate the viscosity to 90K, and thus obtaining the finished product.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a water-based environment-friendly anion coating with good antibacterial and aging resistance and a preparation method thereof. Background technique: [0002] In recent years, SARS, bird flu and the recent outbreak of H1N1 influenza have posed a great threat to human health. To effectively prevent the growth, reproduction, spread and spread of microorganisms, in addition to environmental disinfection and general infectious disease prevention measures , the use of antibacterial materials is the simplest, safest and most effective method. Adding an antibacterial agent to the paint can save the daily disinfection of the wall and achieve environmental protection. Chinese patent application ZL03129256.9 "Antibacterial Negative Ion Coating" introduces an antibacterial agent with silver as a carrier, and the use cost is relatively high. [0003] With the improvement of people's livi...
