A kind of low-cost environmental-protecting interior wall coating
Technical field
The present invention relates to the architectural decorative and fitting materials field, particularly a kind of low-cost environmental-protecting interior wall coating.
Background technology
The trade sales coating that China produces at present mainly contains two big types: the one, and the synthetic resin emulsion class comprises vinyl acetate-acrylic latex paint, styrene-acrylic latex coating, vinylchlorid-vinylidene chloride rubber-emulsion paint, polyvinyl acetate lacquer, epoxy-acrylic latex coating etc.; The 2nd, the inorganic polymer class mainly comprises with silicate, silicon sol serving as the various inorganic architectural coatings of basis preparation.
Along with house decorative material is used more and more widely, it is the third generation pollution period of sign that the present mankind begin to get into the indoor pollution.Generally acknowledge that in the world indoor pollution is to the maximum place of public health harm.The characteristics of room air pollution are following: the obnoxious flavour that distributes in indoor building materials and the furniture, and amount of positive ions is many, and negative ion is few, and CO content is high, the refuse waste gas of people and animal etc.The harmful substances that mainly contains of indoor generation has the generations such as incomplete combustion by volatilization, household fuel and the tobacco leaf of material of construction, house decorative material and daily necessities of 1. formaldehyde-mainly.2. ammonia-by evaporating in finishing material, building structure such as the body of wall.3. VOC VOC-is less than or equal to any organic cpds of 250 ℃ from boiling point or fusing point, like sharp paint, coating, tackiness agent, and ground, decorative material for wall surface etc.4. ozone-because generations such as uviolizings, electrical equipment use.5. carbonic acid gas-human body is breathed out and the waste gas of fuel combustion.
At present, domestic, especially in the area that are fairly developed economically; Some can discharge the low-grade construction coating for internal wall of toxic gas; Superseded basically in market, generally use medium-to-high grade environmental-protection construction coating for internal wall such as aq. type, latex type, be added with various additives in some high-grade paint to eliminate various pollutions targetedly; Like anti-methanal paint, remove the coating of benzene etc.These coating have good film-forming property, film have excellent water tolerance, weathering resistance, anti-stain characteristic, environmental pollution be very little.But these coating remain in some shortcomings: the one, and raw materials cost is higher, has particularly added the coating of the additive with activeconstituents, often adds the Nano titanium dioxide powder in the methanal paint as removing, and causes price more expensive; The 2nd, production technique need heat, energy consumption is big; The 3rd, production technique is complicated; The 4th, some auxiliary agent that adds in producing still can discharge toxic gas, though environmental pollution is less, but still can produce certain negative impact.The high price of this type coating causes many Rural areass and economic backward area, still at a large amount of low-grade construction coating for internal wall that environment had pollution that use.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide the low-cost environmental-protecting interior wall coating, have coating problem with high costs now to solve, and these coating materials is simple, environmental protection.
To achieve these goals, the technical scheme that the present invention adopted is following:
A kind of low-cost environmental-protecting coating, it is made up of following component by weight percentage: the water of straw powder material 30-40%, lime carbonate 10-15%, magnesiumcarbonate 10-15%, wilkinite 10-15%, Natvosol 2-3%, white glue with vinyl 3-5% and surplus is formed; The preparation method of wherein said straw powder material is: straw is cleaned the back with an amount of chlorinated lime bleaching, use 12-15% high-purity zinc oxide aqueous solution soaking then, carry out high temperature drying then and handle, be ground into ultrafine powder through kibbler at last.
Preferred said coating is made up of following component by weight percentage: the water of straw powder material 32-38%, lime carbonate 12-14%, magnesiumcarbonate 11-13%, wilkinite 10-13%, Natvosol 2.2-2.8%, white glue with vinyl 3.2-4.5% and surplus is formed.
Preferred said coating is made up of following component by weight percentage: the water of straw powder material 34-36%, lime carbonate 13%, magnesiumcarbonate 12%, wilkinite 11-13%, Natvosol 2.4-2.6%, white glue with vinyl 3.8-4.2% and surplus is formed.
Preferred said coating is made up of following component by weight percentage: the water of straw powder material 35%, lime carbonate 13%, magnesiumcarbonate 12%, wilkinite 12%, Natvosol 2.5%, white glue with vinyl 4.0% and surplus is formed.
Described lime carbonate, magnesiumcarbonate, wilkinite, Natvosol and white glue with vinyl are technical grade.
The beneficial effect of prepared coating of the present invention is:
1. creationaryly in coating, add reproducible biomaterial: straw powder material, it soaks the back and sterilization and anticorrosion after the pyroprocessing through ZPO, can satisfy user demand, and nontoxic, but and moisture absorption protection against the tide after adding in the coating.
In the material therefor except that a small amount of Natvosol and white glue with vinyl as caking agent as thickening material; The zinc oxide of lime carbonate, magnesiumcarbonate and wilkinite and immersion usefulness is the inorganic materials of nontoxic pollution-free; And stalk powder belongs to biological recyclable materials, so the prepared coating environmental protection.
3. because the raw material sources that adopted are extensive; With low cost; Particularly wherein reproducible straw powder material occupies larger proportion; Therefore significantly reduce the cost of coating, its cost of tool measuring and calculating only is equivalent to the 1/3-1/5 of generic latex lacquer such as styrene-acrylic latex coating, has been equivalent to add the 1/8-1/10 of functional additive coating.Therefore, even also can bear and use this coating fully to Rural areas and economic backward area.
