preparation example Construction

[0033] The application also provides a preparation method for preparing any one of the above-mentioned light-resistant water-based environmental protection real stone paints, comprising the following steps:

[0034] 1) First add 20-23 parts of water-based acrylic resin emulsion to 80-85 parts of modified filling material, keep the constant temperature at 50°C, and fully stir for 8-10 minutes;

[0035] 2) Add 6-8 parts of film-forming aid and 2-3 parts of defoamer, stir for 8-15 minutes, cool down to room temperature naturally, and pack to obtain the finished product.

preparation example 1

[0038] The preparation method of modified filling material comprises the following steps:

[0039] 1) Soak 50 parts of quartz sand in 25 parts by weight of 15% glacial acetic acid aqueous solution and stir for 5 minutes, filter and dry;

[0040] 2) Add 5 parts of octyl 2-hydroxybenzoate to the dried quartz sand and mix and stir for 2 minutes;

[0041] 3) Add 5 parts of carboxymethyl cellulose, 4 parts of alcohol ether water-based co-solvent and 76 parts of deionized water and mix and stir for 5 minutes;

[0042] 4) Stop stirring, and filter out part of the liquid so that the solid content accounts for 50% of the total weight, that is, the modified filling material is obtained.

[0044] The preparation method of modified filling material comprises the following steps:

[0045] 1) Soak 55 parts of quartz sand in 27 parts by weight of 20% glacial acetic acid aqueous solution and stir for 10 minutes, filter and dry;

[0046] 2) Add 8 parts of octyl 2-hydroxybenzoate to the dried quartz sand and mix and stir for 5 minutes;

[0047] 3) Add 8 parts of carboxymethyl cellulose, 5 parts of alcohol ether water-based co-solvent and 80 parts of deionized water and mix and stir for 10 minutes;

[0048] 4) Stop stirring, and filter out part of the liquid so that the solid content accounts for 50% of the total weight, that is, the modified filling material is obtained.

Abstract

The invention relates to light-resistant water-based environment-friendly stone-like paint and a preparation method thereof. A prepared modification filling material is added, and in the modificationfilling material, 2-hydroxybenzoic acid octyl ester can improve light resistance, and carboxymethyl cellulose can improve adhesion strength and stability of the internal structure; a water-based cosolvent and deionized water are added for dissolution and dispersion; a glacial acetic acid water solution can remove impurities in quartz sand, and fine holes formed by impurity removal impurities are to be filled, wherein the effect of the 2-hydroxybenzoic acid octyl ester and the carboxymethyl cellulose can be fully exerted by the fine pore structure, and the internal adhesion strength and stability can be improved. According to the technical scheme, a water-based acrylic resin emulsion is used, and the characteristics of weather resistance, light resistance, heat resistance, corrosion resistance, film coating fullness and the like of the water-based acrylic resin emulsion are fully exerted; and then a coalescing agent and a defoaming agent with a certain ratio are added to obtain the light-resistant water-based environment-friendly real stone-like paint which has the characteristics of good light resistance, strong adhesion, stable structure, no powder falling and the like.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to a light-resistant water-based environmental protection real stone paint and a preparation method thereof. Background technique [0002] In addition to general wall coatings, architectural coatings also include some special appearance and texture exterior wall coatings, such as real stone paint. [0003] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors, and it is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. [0004] Real stone paint has strong decorative properties, wide applicability, good durability, and is not easy to fade. Therefore, it has become a popular exterior wall decorative paint. However, real paint that is exposed to sunlight for a long time on the sunny side will still fade and change color. I...
