Embodiment

[0031] (1) Preparation of clay color paste (solid content, %: 72±2): Take 700g of clay powder, 15g of dispersant, 3g of wetting and leveling agent, 282g of deionized water, stir well and grind at high speed to disperse to fineness≤ 20μm, filter and discharge;

[0032] (2) Prepare the synthetic raw materials of water-based silicone resin according to Table 1:

[0033] Table 1. Synthetic raw materials of waterborne silicone resin

[0034]

[0035] Synthesis of water-based acrylic modified silicone resin: add deionized water and acidic catalyst in turn to the reaction vessel, and mix well. After mixing methyltrimethoxysilane, phenyltrimethoxysilane and ethyl orthosilicate evenly, add them to the reaction vessel at one time, and continue to stir at room temperature for 6 minutes until the mixture becomes a uniform and transparent solution. After adding CGR-1268 water-based acrylic resin and stirring evenly, the water-based acrylic modified silicone resin is obtained.

Abstract

The invention discloses a high-weather-resistance water-based imitation argil coating and a preparation method thereof. The high-weather-resistance water-based argil-imitating coating is prepared from the following components in parts by weight: 25 to 50 parts of water-based acrylic acid modified organic silicon resin and 50 to 75 parts of argil color paste, wherein the water-based acrylic acid modified organic silicon resin is a physical mixture of water-based acrylic resin and water-based organic silicon resin, and the mass fraction of the water-based organic silicon resin is 50-60% and the mass fraction of the water-based acrylic resin is 40-50% according to the solid content; and the water-based organic silicon resin is synthesized from the following raw materials in parts by weight: 60 to 65 parts of methyl trialkoxysilane, 0 to 5 parts of phenyl trialkoxysilane, 0 to 3 parts of tetraalkoxysilane, 30 to 35 parts of deionized water and 0.1 to 0.4 part of acid catalyst.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a highly weather-resistant water-based clay imitation coating and a preparation method thereof. Background technique [0002] Clay tiles are made of clay and other composites into wet embryos and then fired at a high temperature of about 1200 ° C. They are widely used in the local characteristic construction industry in our country. However, due to the increasing scarcity of natural five-color clay and the heavy and fragile ceramic tile itself, the application in high-rise buildings has been limited. It is also a green and environmentally friendly new imitation pottery building material. [0003] Water-based imitation pottery paint with high weather resistance can be sprayed on aluminum alloy and calcium silicate board with a dry film thickness of 30-50 μm. It can not only imitate the appearance of clay products, but also embodies the characteristics of resource saving and environmental ...
