Problems solved by technology

But at the same time, some existing wall glazes only have the advantages of simple smoothness, corrosion resistance and friction resistance. Both limit the application environment and fields of wall glaze materials, which ultimately leads to the obstruction of the expansion of the market application range of wall glaze

Embodiment 1

[0064] Embodiment 1 The first aspect provides a light-resistant and water-resistant architectural interior and exterior wall glaze. The raw materials include at least the following mass percentages: 14% of cationic emulsion, 8% of nano-silica sol, 6% of modified titanium dioxide, and 45% of mineral salt , chitosan antibacterial agent 1%, deionized water to supplement the balance.

[0065] Cationic emulsion: cationic hydroxyl silicone oil emulsion and cationic polyacrylamide emulsion, the mass ratio is 3:11.

[0066] The preparation method of modified titanium dioxide is (in parts by weight): (1) Dissolve 5 parts of succinic anhydride in 50 parts of DMF solution, add 5 parts of 3-aminopropyltriethoxysilane, and put Heating and stirring for 3 hours; (2) adding 20 parts of DMF solutions containing 1 part of titanium dioxide dropwise into the reaction solution, and continuing to stir and react for 3.5 hours to obtain pretreated titanium dioxide particles; (3) mixing pretreated tit...

Embodiment 2

[0077] The specific implementation of this example is the same as that of Example 1, except that the mass ratio of the cationic hydroxyl silicone oil emulsion to the cationic polyacrylamide emulsion is 4:10.

Embodiment 3

[0079] The specific implementation of this example is the same as that of Example 1, except that the mass percentage of the modified titanium dioxide is 5%.

Abstract

The invention discloses a light-resistant and washing-resistant building interior and exterior wall glaze and a preparation method thereof. The light-resistant and washing-resistant building interior and exterior wall glaze at least comprises the following raw materials in percentage by mass: 10-15% of cationic emulsion, 5-15% of sol colloid, 5-10% of modified nanoparticles, 30-50% of mineral salt, 1-5% of auxiliaries and the balance of deionized water. The prepared wall glaze has good light resistance, water resistance and cleaning performance, effectively reduces the content of formaldehyde and other harmful gases, is suitable for being popularized in the field of wall coatings, and has wide development prospects.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a light-resistant and water-resistant building interior and exterior wall glaze and a preparation method thereof. Background technique [0002] At present, the coatings of building materials used in the market are usually epoxy resin raw materials, with pigments, solvents and additives added. However, in today's architectural decoration industry, the existing common interior wall coatings have obvious shortcomings such as poor covering ability, easy powder removal, and inability to wash. The requirements of coatings are no longer satisfied with simple coatings. [0003] In recent years, wall glaze has received more and more attention as a new architectural coating. But at the same time, some existing wall glazes only have the advantages of simple smoothness, corrosion resistance and friction resistance. Both limit the application environment and fields of wall glaze mater...
