Problems solved by technology

[0003] In order to achieve a certain decorative effect, organic coatings have high requirements on the flatness of the substrate and require multiple constructions. The coating usually has defects such as poor adhesion, easy foaming, cracking, and poor durability. Although the color is rich, the surface effect It is mainly flat, and it is difficult to make various three-dimensional or texture effects

Embodiment 1

[0018] The composition and percentage by weight of the present embodiment are: 20.0% of No. 425 white cement, 8.0% of redispersible latex powder, 0.2% of hydroxypropyl methylcellulose, 0.3% of water-repellent organic silicon powder, 0.5% of wood fiber, 56.0% of 80-120 mesh colored sand, 15.0% of 325 mesh quartz powder.

[0019] Use the inorganic dry powder texture paint that embodiment 1 gains: water=100: 30~35 (weight ratio) cutting; First batch scrape once, after 4 hours, use nap roller roller to coat again, curing seven days, can obtain texture strong, decorative Highly resistant, napped coating.

Embodiment 2

[0021] The composition and weight percent of this embodiment are: 28.0% of No. 425 white cement, 6.5% of redispersible latex powder, 0.35% of hydroxypropyl methylcellulose, 0.25% of water-repellent organic silicon powder, 0.4% of wood fiber, inorganic Pigment iron oxide red 0.1%, 80-120 mesh colored sand 54.55%, 325 mesh quartz powder 10.0%.

[0022] With the inorganic dry powder texture paint that embodiment 2 gains: water=100: 25~30 (weight ratio) cutting; Batch scraping twice, curing seven days, can obtain the coating that has strong texture, highly decorated artificial stone effect.

Embodiment 3

[0024] The composition and weight percent of this embodiment are: No. 425 white cement 35.0%, redispersible latex powder 4.0%, hydroxyethyl methylcellulose 0.3%, water repellent 0.4%, wood fiber 0.2%, inorganic pigment iron oxide Yellow 0.2%, 40-80 mesh colored sand 5%, 80-120 mesh colored sand 46.9%, 325 mesh quartz powder 8.0%.

[0025] Use the inorganic dry powder texture coating obtained in Example 3: water=100:25~30 (weight ratio) to cut the material; directly use the embossing roller to coat it once, and maintain it for seven days to obtain a strong texture and a very high decoration with special texture. Textured effect coating.

Abstract

A inorganic dry powder paint with good mass sensation is prepared proportionally from cement, color sand, re-dispersed emulsoid powder, hydrophobic agent, inorganic pigment and filler. Its advantages are high adhesion to concrete, high weatherability, good air permeability, and no pollution. Its application method is also disclosed.

Description

technical field [0001] The invention relates to an architectural coating, in particular to an inorganic dry powder texture coating which can be used on the inner and outer walls of buildings. technical background [0002] Most of the current architectural coatings are organic coatings with synthetic resin as the main film-forming substance. The raw material of synthetic resin mainly comes from petroleum, and petroleum is a non-renewable resource. With the development of society, petroleum as a major energy source and Important chemical raw materials are facing depletion due to massive exploitation, resulting in increasingly tight supply and an oil crisis. Moreover, a certain amount of organic solvents will be used in the process of manufacturing and construction of organic coatings. These organic solvents also come from petroleum, and these organic solvents will be directly discharged into the atmosphere during the production and construction of coatings, which will not only...
