Embodiment 1-4

[0044] A kind of relief powder for exterior wall of the present invention, each embodiment concrete implementation component distribution ratio as shown in table 1:

[0045]

[0046] The preparation method of above-mentioned external wall relief powder comprises the steps:

[0047] Turn on the putty powder mixing equipment, put the accurately weighed white cement, quartz powder (4 / 5 of the total mass of the quartz powder), and quartz sand into the feeding port in sequence. After stirring for 3 minutes, add water repellent and thixotropic agent one after another Wood fiber, PVA, methyl hydroxyethyl cellulose, and then put in the remaining quartz powder (1 / 5 of the total mass of the quartz powder), stir for 5 minutes, take out the material from the feeding port, add water 35wt% to measure the consistency of the product, and the temperature The temperature is 25±2°C, the viscosity is 12.5-13.5 rings, and the relief powder for exterior walls can be obtained without any obstacle...

Abstract

The invention discloses embossment powder for an outer wall, and a preparation method thereof, and relates to the field of coating. The embossment powder for the outer wall comprises the following components in parts by mass: 20 to 25 parts of white cement, 50 to 65 parts of quartz powder, 10 to 20 parts of quartz sand, 0.1 to 0.15 part of a water repellent, 0.2 to 0.5 part of a thixotropic agent, 0.2 to 0.3 part of wood fiber, 1 to 1.5 parts of PVA and 0.3 to 0.5 part of methyl hydroxyethyl cellulose. The embossment powder provided by the invention belongs to a layer material in inorganic embossment, and has the characteristics of environmental friendliness, high whiteness, low alkalinity, high adhesive strength, small drying shrinkage, high water-proof and air-permeable properties and the like. Compared with the coating in the traditional embossment, the embossment powder is high in cost performance, uniform in spot, plump and high in stereoscopic sensation, and has development prospect in the field of outer wall texture effect decoration.

Description

technical field [0001] The invention relates to the field of coatings. Background technique [0002] With the promotion and application of multilayer coatings in my country, a large number of products have emerged in the market, which also reflects different types of products, such as synthetic resin emulsions, reaction curing types, silicates, polymer cements, and product quality varies. Qi, and the market price is chaotic, often at a lower price to win the market's recognition. [0003] Synthetic resin emulsion embossed mid-layer materials are expensive and have a short shelf life; reaction-cured type has a short construction period; the pH value of the surface of silicate is too high, and it is easy to return to alkali and bloom; the quality of polymers is uneven, and the surface High pH, ​​low bond strength, and low flexibility; there are also many problems in the current market. Contents of the invention [0004] The technical problem to be solved by the present inve...
