Embodiment 1

[0032] The present embodiment is made by following raw material proportioning, is by weight ratio:

[0033] Deionized water 55, butyl acrylate 20, methyl methacrylate 15, acrylic acid 1.5, styrene 15, oleic acid modified nano titanium dioxide 0.6, ammonium persulfate 0.5, sodium bicarbonate 0.3, emulsifier 2.5, dilute ammonia water 1 ;

[0034] The production steps are as follows:

[0035] a. First take 30% of the formula amount of emulsifier and formula amount of sodium bicarbonate and put it into 90% of the formula amount of deionized water to dissolve the emulsifier;

[0036] b. Add butyl acrylate monomer, methyl methacrylate monomer, styrene monomer and 60% acrylic acid monomer in formula quantity during stirring, and obtain pre-emulsion after high-speed stirring for 30 minutes;

[0037] C, get the oleic acid modified nano-titanium dioxide of formula quantity and add remaining emulsifier, the persulfate of formula quantity and remaining deionized water;

[0038] d. Heat...

Embodiment 2

[0042] The present embodiment is made by following raw material proportioning, is by weight ratio:

[0043] Deionized water 55, butyl acrylate 20, methyl methacrylate 15, acrylic acid 1.5, styrene 15, oleic acid modified nano titanium dioxide 0.7, potassium persulfate 0.5, sodium bicarbonate 0.3, emulsifier 2.5, dilute ammonia water 1 ;

[0044] Its preparation steps are identical with embodiment 1.

Abstract

The invention discloses a coating for interior architecture, and relates to the technical field of building coatings. The coating is prepared from oleic acid modified nano titanium dioxide styrene-acrylic composite emulsion; the coating is prepared from the following components in parts by weight: 45-55 parts of deionized water, 15-20 parts of butyl acrylate, 10-15 parts of methyl methacrylate, 0.8-2 parts of acrylic acid, 10-15 parts of styrene, 0.2-1 part of oleic acid modified nano titanium dioxide, 0.3-0.5 part of persulfate, 0.18-0.3 part of sodium bicarbonate, 1.5-3 parts of an emulsifier and 0.5-1 part of a pH regulator. By developing the oleic acid modified nano titanium dioxide styrene-acrylic composite emulsion, the coating is enabled to have high tensile strength, good thermal stability and water resistance and high hardness; furthermore, the coating has better ultraviolet absorption capacity and a wider ultraviolet absorption band; when being used in a room, the coating hasbetter antibacterial effect and indoor organic matter degradation capacity.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to a coating for indoor architecture and a preparation method thereof. Background technique [0002] With the development of my country's economy and society, people's living standards continue to improve, and people pay more and more attention to home environment decoration. However, due to the use of resins and adhesives in various indoor decoration materials and furniture, harmful substances contained in them are released. Finally, it will cause indoor air pollution, mainly including organic volatiles such as formaldehyde, toluene and xylene, among which, formaldehyde has the greatest impact on human health. Solving indoor environmental pollution has become a hot spot that people pay attention to at present. [0003] Interior wall paint has the characteristics of a large coating area. If it is endowed with the function of air purification, it will play an important...
