Embodiment 8

[0023] The construction waste particles used in Example 8 are particles with a particle size of 3mm-200 mesh formed by cleaning, crushing and grading waste concrete, mortar and facing bricks.

Embodiment 9

[0024] The construction waste particles used in Example 9 are particles with a particle size of 3mm-200 mesh formed by cleaning, crushing and grading waste mortar, brick tiles and veneer bricks.

[0025] The contents of each component in the following examples are by weight percent.

[0026] According to "Synthetic Emulsion Environmentally Friendly Sand Wall Architectural Coatings" JG / T24-2000 and reference standards, the performance of the coatings obtained in the following examples was tested.

Embodiment 1

[0028]Dispersant SN-Dispersant-5040 0.15% (percentage by weight), defoamer NOPCO NXZ 0.3% (percentage by weight), thickener Acrysol TT-935 0.5% (percentage by weight), antifungal agent Skane M-8 0.15% (percentage by weight), film-forming aid lauryl ester alcohol 0.5% (percentage by weight), construction waste particles 66.4% and water (percentage by weight) 17% mix, after high-speed stirring, then add 15% (percentage by weight) The full acrylate copolymer emulsion AC-261, and stirred evenly to obtain an environmentally friendly sand wall-like architectural coating. The properties of the coatings were measured as follows:

[0029] Water resistance: No bulging, cracking or peeling of the coating within 30 days.

[0030] Alkali resistance: 30 days without bulging, cracking and peeling of the coating.

[0031] Coating resistance to temperature change: 10 coatings without powdering, cracking, peeling, and bulging.

[0032] State in the container: After stirring, there is no aggl...

Abstract

The sandy wall shaped building paint consists of base material acrylic acid emulsion; assistant including dispersant, anti-bubbling agent, thickener, filming assistant and optional anti-mildew agent; stuffing, which is building garbage grain, artificial color sand and / or natural sand in the granularity from 200 mesh to 3 mm; and water. The present invention prepares sandy wall shaped building paint with waste concrete, mortar, brick and tile, and other building garbage and has the similar performance as sandy wall shaped building paint with natural sand.

Description

technical field [0001] The present invention relates to an environment-friendly sand-wall-like architectural coating and its preparation method, in particular to a kind of filler whose filler is made of all or part of waste concrete, mortar, brick tiles or various types of veneer bricks or a mixture of at least two of them after crushing and screening. An environment-friendly sand wall-like architectural coating composed of a single or a mixture of several particle sizes obtained after separation and a preparation method thereof. Background technique [0002] At present, the fillers of environmentally friendly sand-walled architectural coatings on the market mainly contain natural sand and / or artificial sand, but natural sand is a non-renewable resource. Due to a large amount of use, sand and gravel resources are already facing the danger of resource shortage. Therefore, The resource depletion and environmental damage caused by massive sand and gravel mining have aroused wid...
