Abstract
A natural building exterior wall coating is mixed by raw materials including, by weight, from 120 to 220 parts of white cement, from 200 to 350 parts of lime putty, from 4.2 to 6.9 parts of alum, from 50 to 150 parts of white stone powder, from 0.7 to 1.9 parts of rubber sap, from 0.5 to 1.5 parts of pigment and from 50 to 80 parts of water. Particular preparation method include crushing the white stone powder and the alum; then mixing the white cement with the lime putty, feeding mixture of the cement and the lime putty into a blender, sequentially feeding the crushed white stone powder and the crushed alum into the blender, uniformly stirring the materials in the blender, then adding the rubber sap into the blender and uniformly mixing the materials in the blender; and discharging dry solid after stirring, adding the water and the pigment into the solid and preparing the natural building exterior wall coating finished product. The natural building exterior wall coating has excellent technical performances and is low in cost, the consumed raw materials are natural, non-toxic and harmless, resources can be saved, environments are protected, and the natural building exterior wall coating can be widely applied to exterior coating projects of various buildings.
Description
Technical field
The present invention relates to the coating engineering technical field of external wall, especially relate to a kind of building external paint that adopts the natural materials preparation.
Background technology
Trade sales coating more and more becomes the important symbol of a national national life level as one type in the coatings industry.Architectural Paint in China has possessed suitable scale and certain basis in the development that has obtained in recent years advancing by leaps and bounds.Exterior coating is compared with other exterior wall finish materials and had following advantage: economically, decoration of exterior wall adopts coating more than adopting considerably cheapers such as glass curtain wall, TERRAZZO, aluminium-plastic panel; Coating variety is many, and easy construction can satisfy the requirement of the different class of decoration of exterior wall; Good decorating effect, rich color, lucid and lively, replaceable color, the feeling of freshness of maintenance buildings can be expressed abundanter design style; Light weight, safety is beneficial to antidetonation; There is not the potential safety hazard of falling; Energy consumption is low.When national chemical building material industry the Tenth Five-Year Plan (2001-2005), account for more than 60% with regard to the application that proposes the trade sales coating decoration of outside wall; Along with further developing of China's economic construction; The trade sales coating industry has encouraging prospects, and social base is provided for the research and development of trade sales coating and development.
The present used starting material of coating on the market are staple with water-base resin, nano-meter flame retardants, ammonium polyphosphate, trimeric cyanamide, carbon forming agent, nanometer face, filler, dispersion agent and stablizer mainly; Its drawback is that chemical components is many; Because of it is a water-borne coatings, contain formaldehyde, the pure ethers chemical ingredients of low amount in the solvent for use.And this series products poor stability, poor water resistance, surface contaminant is prone to make the generation shrinkage cavity of filming.
Summary of the invention
To the problems referred to above that prior art exists, the applicant provides a kind of pure natural building external paint.The present invention has good technical performance, and cost is low, and used starting material Nantural non-toxic does not have harm, can economize on resources, and protects environment, can be widely used in the external-wall coating engineering of all kinds of buildings.
Technical scheme of the present invention is following:
A kind of pure natural building external paint is formed by the raw materials mix of following weight part: 120 ~ 220 parts of white cements, 200 ~ 350 parts of lime putties, 4.2 ~ 6.9 parts in alum, 50 ~ 150 parts of white stone powders, 0.7 ~ 1.9 part of rubber myron, 0.5 ~ 1.5 part in colorant, 50 ~ 80 parts in water.Concrete preparation process is: at first white stone powder, alum are pulverized; Then white cement, lime putty are mixed, drop in the stirrer, again the white stone powder that crushes, alum are dropped into successively, evenly stir, add the rubber myron then and evenly stir; Mixed dried solid after the stirring discharging is modulated into pure natural building external paint finished product again through adding the step of water, colorant.
Beneficial technical effects of the present invention is:
White cement during the present invention is raw materials used is the abbreviation of white portland cement, and lime putty is a white lime cream; White stone powder is to form through mechanical disintegration, screening with white marble and calcite, and calcium carbonate content is high, and purity and whiteness are very high, fine size (5-1250 order), strong covering power; The rubber myron is the tree elastomer myron in Hainan Island.
In above-mentioned raw materials, white cement, lime putty are as sticker; Alum is as peptizer, and effective constituent is Al
2O
3, SO
3, can react with cement-hydrate, generate ettringite, can quicken the aquation and the sclerosis of cement, in addition, the waterproof action of alum has improved the performance of the water-tight corrosion-proof of coating; The white stone powder calcium carbonate content is high, has levelling, anti-abrasive property and certain opacifying power, can also improve processing characteristics, play the effect of reinforcement and half reinforcement; Colorant has the toning effect; The rubber myron has good activity and bonding capacity as the natural consolidation agent, and the rubber myron is natural matter, and is nonpoisonous and tasteless, cheap, meets recycling economy and requirement on environmental protection.
Product of the present invention has outstanding economic benefit, has saved the cost of plastic tank.According to ready market price contrast,, need to use 4500 tons of coating if 1,000 ten thousand flat external walls are arranged; Need to use (100 jin/barrel of 90000 plastic tanks; 0.9 jin/flat), measuring and calculating thus is if use product of the present invention can save 90000 of plastic tanks; By 3.5 yuan of calculating of 1 plastic tank, can practice thrift 315000 yuan of the money of plastic tank.
The pure natural exterior coating that the present invention produces has good flame retardancy, the exterior wall smooth of brushing product of the present invention, and leakless produces, and has certain compression strength and heat-insulating property.
Embodiment
The inventive method is implemented according to following steps:
(1) white stone powder, alum are ground into the fine particle shape with kibbler.
(2) white cement, lime putty are mixed, drop in the stirrer, again the white stone powder that crushes, alum amount is according to a certain ratio dropped into successively, add the rubber myron then and evenly stir.
(3) mixing after the stirring discharging done solid-like again through adding the step that water adds colorant, is modulated into thick liquid shape finished product.
Product embodiments 1 to embodiment 4 used raw material weight umber of the present invention is seen table 1, and unit is kg.
