Abstract

The invention discloses an antibacterial and anti-mildew interior wall latex paint, and belongs to the field of architectural coating materials. According to the present invention, after diatomaceousearth and fly ash are subjected to mixing acid leaching, and filtering is performed to load SiO2, TiO2 and other oxides on the diatomaceous earth, wherein the TiO2 acts with positively charged chitosan, and the chitosan and the layered structure pretreated diatomaceous earth are mixed so as to effectively improve the internal swelling property and the mechanical property; through the good cooperation effect with the chitosan, the antibacterial and anti-mildew performance can be further increased after the combining; a polyurethane emulsion is prepared by using propylene glycol polyether, phorone diisocyanate and other raw materials, modification is performed by adding an oil material, and the good hydrophobicity can be achieved by introducing a long-chain fatty chain segment so as to improve the water-blocking property; the product has antibacterial property, and can have the improved antibacterial effect by combining with Cinnamomum camphora essential oil and lavender essential oil soas to achieve the effects of water resistance and antibacterial effect and improve the anti-mildew effect; and the antibacterial and anti-mildew interior wall latex paint of the present invention cansolve the problem of poor antibacterial and anti-mildew effect of the current commonly-used internal wall latex paint.

Description

technical field [0001] The invention belongs to the field of architectural coatings, in particular to a bacteriostatic and anti-mildew interior wall latex paint. Background technique [0002] The most used type of architectural coatings is interior wall latex paint with high pigment volume concentration, which is widely used due to its low price and proper decorative function. In terms of its performance, this type of latex paint has good hiding power and appropriate scrub resistance, and most of them can meet the requirements of GB / T9756-2001 "Synthetic Resin Emulsion Interior Wall Coatings" and GB18582-2001 "Interior Decoration Materials for Interior Walls". Limits of Hazardous Substances in Coatings". However, the deficiencies of this type of coating: First, the rheology of the coating is poor, the leveling property is poor, and the decorative effect and feel of the coating film are not good; the second is that some properties (washing resistance and contrast ratio, etc....
