Abstract

The invention discloses a dirt-resistant elastic emulsion paint and a preparation method thereof, belonging to the field of building materials. A redox initiator FF6M and ammonium persulfate are compounded to carry out core-shell emulsion polymerization reaction to obtain block polymer similar to styrene-acrylic emulsion to form emulsion paint base material, which improves the density of emulsionpaint film formation, and ensures the corrosion resistance and water resistance of the coating film. Silane coupling agent N-Beta-aminoethyl-gamma-aminopropyl trimethoxysilane, tetrabutyl titanate andtetraethyl orthosilicate are used as main raw materials to prepare auxiliary resin, the auxiliary resin is compounded with the emulsion paint base material to produce superoxide anion radical.O2<-> and hydroxyl radical.OH, so as to decompose the amino acids for forming bacteria and sugars which maintain their physiological activities, and kill bacteria or inhibit their growth. The dirt-resistantelastic emulsion paint has antimicrobial activity. The dirt-resistant elastic emulsion paint solves the problems of poor stain resistance and poor elasticity of the current latex paint.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a stain-resistant elastic latex paint and a preparation method thereof. Background technique [0002] Latex paint is a kind of paint made by using synthetic resin emulsion as film-forming substance, using water as solvent, adding pigments, fillers and additives, and going through a certain process. Latex paint is a mixture of a dispersion of synthetic resin (latex) solid particles in water and a dispersion of pigment and filler particles in water. [0003] The elasticity of latex paint film is an important property of latex paint, which can directly affect the mechanical properties of latex paint film. Therefore, the coating film performance of latex paint is an important index to evaluate the comprehensive performance of latex paint, and it is also an important factor to measure the quality of latex paint products. [0004] The main function of latex paint is to d...
