Novel long-acting broad-spectrum bacteriostatic and antibacterial multifunctional water-based architectural coating and preparation method thereof

Abstract

The invention discloses a novel long-acting broad-spectrum bacteriostatic and antibacterial multifunctional water-based building coating and a preparation method thereof. The coating is prepared by compounding the following raw materials: water-based emulsion, pigment filler, a water-based functional aid, a water-based nano-composite bacteriostatic and antibacterial agent, deionized water and thelike. The coating is environment-friendly, does not generate drug resistance, does not have in-vivo accumulation, forms effective protection after coating the surface of a base material, and is long-acting, broad-spectrum and durable in bactriostasis and antibacterial effect while being strong in decoration. According to the invention, nano metal ions with stable functional ions are further introduced, and the water-based nano composite bacteriostatic and antibacterial agent is prepared by grafting and nano composite technologies, so that the defects of high toxicity, low activity, poor application performance in different environments and the like of the traditional bacteriostatic and antibacterial material product are overcome. The product provided by the invention can form an automaticadjustment bacteriostatic and antibacterial base system in a severe environment, inhibits mutual aggregation and derivation of microorganisms and bacteria in a long-acting and broad-spectrum manner, and is a long-acting and ecological bacteriostatic, antibacterial and mildew-proof material.

Description

[0001] Technical field [0002] The embodiment of the present invention relates to the technical field of functional fine building materials, specifically a novel long-acting broad-spectrum antibacterial and antibacterial multifunctional water-based architectural coating and a preparation method thereof. Background technique [0003] As the country pays more and more attention to environmental protection, a series of environmental protection laws and regulations have been promulgated and implemented one after another. The rapid development of modern infrastructure has continuously put forward higher requirements for the properties and functions of building materials. These have played a role in promoting the transformation and upgrading of the building materials industry. As one of the important means of external protection for building base facilities, architectural protective coatings are developing towards water-based, high-performance, multi-functional, pollution-free, and ...
