The present invention starts with the research of the performance characteristics of the waste concrete, the sand pulp, the tiles and all kinds of furring bricks, and produces the sandy wall-shaped building paint whose performance indexes are identical to that of sandy wall-shaped building paint with natural sand as filling material.
Description
Technical field
The present invention relates to a kind of environment-friendly type sand textured building coating and preparation method thereof, particularly relate to a kind of its filler by all or part of waste and old concrete, mortar, brick and tile or all kinds of furring brick or environment-friendly type sand textured building coating of forming of the mixture of single or several grades of after broken, screening, obtaining of at least two kinds mixture and preparation method thereof wherein.
Background technology
The filler of environment-friendly type sand textured building coating in the market mainly contains natural sand and/or artificial sand, but natural sandstone belongs to Nonrenewable resources, because a large amount of use, sand and stone resources has been faced with the danger of resource breakthrough, therefore, resource exhaustion and the environmental disruption that causes because of a large amount of exploitation sandstones caused that people pay close attention to widely.And on the other hand, increasing building waste (wherein a large amount of is waste and old concrete, mortar, brick and tile, all kinds of furring brick) overwhelming majority that produces in old building maintenance or demolishing process is not passed through any processing, just transported to countryside or rural area by unit in charge of construction, adopt the mode of air storage or landfill to handle, consume a large amount of land acquisitions and take, rubbish flies upward problem and has caused serious secondary pollution again.Regenerated utilization of building waste work at present mainly is that it is used for roadbed, foundation works etc., but above-mentioned application is limited in the future, because except its consumption is limited, also has other industry byproduct such as industrial residue etc. also to want to be used for these fields.Therefore with waste and old concrete, mortar, brick and tile, all kinds of furring brick through clean, after broken, the classification as the filler of environment-friendly type sand textured building coating in order to make the environment-friendly type sand textured building coating, both can reduce cost, save natural sand and stone resources, alleviate the natural resource disparities between supply and demand, can also alleviate the pollution to environment such as waste and old concrete, waste and old brick and waste and old ceramic tile, have good social benefit, environmental benefit and economic benefit.
CN1086282A discloses a kind of fire-retardant sand-wall shaped antistatic ceiling, it contains the sand wall shape material that base-material, softening agent, static inhibitor, film coalescence aid, dispersion agent, thickening material, solvent, filler and tinting material etc. form by base material and substrate surface and is constituted, and its filler is a silica sand.Its shortcoming is that filler is a silica sand.
Summary of the invention
The object of the present invention is to provide a kind of environment-friendly type sand textured building coating.Being characterized in the granularity being waste and old concrete, mortar, brick and tile or the furring brick of 3mm-0.077mm (being equivalent to 200 orders) or at least two kinds mixture (be called for short building waste particle) wherein, is filler for artificial color sand and/or natural sand and above-mentioned building waste particulate mixed thing perhaps.
Another object of the present invention is to provide a kind of preparation method of environment-friendly type sand textured building coating.
In order to achieve the above object, the invention provides a kind of environment-friendly type sand textured building coating, comprise base-material, filler, auxiliary agent and water, wherein base-material is an ACRYLIC EMULSION, auxiliary agent comprises dispersion agent, defoamer, thickening material and film coalescence aid and optional mould inhibitor, it is characterized in that described filler is that granularity is the building waste particle of 3mm-0.077mm (being equivalent to 200 orders) or for artificial color sand and/or natural sand and above-mentioned building waste particulate mixed thing, described building waste particle is waste and old concrete, mortar, brick and tile or furring brick or at least two kinds mixture wherein; The consumption of described base-material is that the consumption of 10-30%, filler is 10-45% for the consumption of 0-1.5%, water for the consumption of 0.5-4%, mould inhibitor for the consumption of 0.5-4%, film coalescence aid for the consumption of 0.2-3%, thickening material for the consumption of 0.1-3%, defoamer by weight percentage by weight percentage by weight percentage by weight percentage by weight percentage by weight percentage for the consumption of 40-70%, dispersion agent by weight percentage by weight percentage.
Furring brick of the present invention comprises all kinds of furring brick, as can be glazed interior tile, wall floor tile, the ceramic mosaic of various patterns and kind.
Natural sand in the filler of the present invention is natural colour sand or natural white sand or the mixture of the two.Artificial color sand, its manufacture method mainly contain two big classes at present, and a class is a high-temperature sintering process, and another kind of is the normal temperature staining.Building waste particulate relative content is 10-100% by weight percentage in the filler of the present invention, and the relative content of artificial color sand and/or natural sand is 0-90% by weight percentage.Wherein what of natural sand add-on do not influence its final performance, just determine the amount of its adding according to ornamental requirement.Filler of the present invention also will be selected suitable grain composition for use as existing sand textured building coating.The general granularity of natural colour sand of selecting is in the 0.995mm-0.295mm scope of (being equivalent to the 20-60 order), the granularity of natural white sand is between 2.5mm to 0.013mm (being equivalent to 120 orders), artificial color sand granularity generally in the 0.995mm-0.295mm scope of (being equivalent to the 20-60 order), building waste particulate granularity is 3mm-0.077mm (being equivalent to 200 orders).Usually granularity will be lacked more than or equal to the coarse particles consumption of 2.5mm, generally should be about 3%, preferably be less than 3%, based on fine particle, can obtain closely knit filming.
Sand textured building coating of the present invention with through the building waste particle of grating different-grain diameter or through building waste particle, artificial color sand and/or the natural sand of grating different-grain diameter as filler, its color of filming directly presents building waste particulate color, and (as the building waste particle based on concrete, it is filmed and can present the tone that grey is the master; Based on the building waste particle of red brick and tile, it is filmed, and can to present brick-red be main tone; Based on the building waste particle of blue bricks or gray watt, it is filmed and can present cyan or grey is main tone; Based on the building waste particle of furring brick, it is filmed, and can be rendered as multiple color be main pattern) or present composite coloured after composite of building waste particle and color sand.The present invention also can be by the natural white sand that is mixed, with adjusting the film color and the quality of facing.Because of the color of filming directly presents composite coloured after composite of building waste particulate color or building waste particle and color sand, thereby, generally need not to use tinting pigment, also can use the very pigment of small proportion as required, with the color of adjusting coating.The disclosed pigment that can be used for sandy paint of prior art all can be used for the present invention, and as being selected from metal oxide, carbon black and pigment dyestuff, wherein metal oxide comprises titanium dioxide, zinc oxide, ultramarine and versicolor metal oxide; Pigment dyestuff can be phthalocyanine blue, phthalocyanine green, lithol red, permanent yellow, permanent bordeaux, organic yellow etc.
