A kind of low-cost environmental-protecting interior wall coating
Technical field
The present invention relates to architectural decorative and fitting materials field, particularly a kind of low-cost environmental-protecting interior wall coating.
Background technology
The building coating that China produces at present mainly contains two large classes: the one, and synthetic resin emulsion class, comprises second thirdEmulsion paint, styrene-acrylic latex coating, vinyl chloride-vinylidene chloride emulsion paint, polyvinyl acetate paint, epoxy-Acrylic latex coating etc.; The 2nd, inorganic polymer class, mainly comprises taking silicate, Ludox as basis preparationVarious inorganic architectural coatings.
More and more extensive along with house decorative material application, the mankind start to enter taking indoor pollution as mark nowThe third generation of will pollutes period. Generally acknowledge that in the world indoor pollution is that public health is endangered to maximum place. ChamberInterior air-polluting feature is as follows: the pernicious gas distributing in indoor building materials and furniture, and amount of positive ions is many,Anion is few, and CO content is high, the refuse waste gas of people and animal etc. 1. the harmful substances that mainly contains of indoor generation hasFormaldehyde-main volatilization, domestic fuel and tobacco leaf by construction material, house decorative material and daily necessitiesThe generations such as imperfect combustion. 2. ammonia-by ornament materials, building structure is as evaporated in body of wall. 3. waveSend out property organic gas VOC-and be less than or equal to any organic compound of 250 DEG C from boiling point or fusing point, as soonDried lacquer, coating, adhesive, ground, decorative material for wall surface etc. 4. ozone-due to ultraviolet ray irradiation, electricityThe generations such as device use. 5. the waste gas of carbon dioxide-characteristics of contaminated respiratory droplets and fuel combustion.
At present, domestic, especially in area that are fairly developed economically, some can discharge the low-grade interior wall of toxic gas and buildBuild coating, substantially superseded in market, generally use the medium-to-high grade environment-friendly type inner wall such as aqua type, latex typeBuilding coating, is added with various additives to eliminate targetedly various pollutions in some high-grade paint, asAnti-methanal paint, removes the coating of benzene etc. These coating have good film-forming property, film have good resistance to water,Weatherability, anti-stain characteristic, environmental pollution are very little. But these coating remain in some shortcomings: the one, and raw material becomesThis is higher, has particularly added the coating of the additive with active component, as often added except in methanal paintPlus nano grade titanium dioxide powder, causes price more expensive; The 2nd, production technology needs to heat, energy consumption is large; The 3rd, rawProduction. art is more complicated; The 4th, some auxiliary agent adding in producing, still can discharge toxic gas, environmental pollutionThough less, but still can produce certain negative effect. The high price of this class coating cause many rural areas andEconomic backward area, still at a large amount of low-grade construction coating for internal wall that environment had to pollution that use.
Summary of the invention
For the deficiencies in the prior art, one of object of the present invention is to provide low-cost environmental-protecting interior wall coating,To solve existing coating problem with high costs, and these coating materials are simple, environmental protection.
To achieve these goals, the technical solution adopted in the present invention is as follows:
A kind of low-cost environmental-protecting coating, it is made up of following component by weight percentage: straw powder material30-40%, calcium carbonate 10-15%, magnesium carbonate 10-15%, bentonite 10-15%, hydroxyethylcellulose 2-3%,The water composition of white glue with vinyl 3-5% and surplus; The preparation method of wherein said straw powder material is: straw is clearWash the appropriate bleaching powder bleaching of rear use, then use 12-15% high-purity zinc oxide aqueous solution soaking, then carry out heightTemperature is dry to be processed, and is finally ground into superfine powder by pulverizer.
Preferred described coating is made up of following component by weight percentage: straw powder material 32-38%, carbonic acidCalcium 12-14%, magnesium carbonate 11-13%, bentonite 10-13%, hydroxyethylcellulose 2.2-2.8%, white glue with vinylThe water composition of 3.2-4.5% and surplus.
Preferred described coating is made up of following component by weight percentage: straw powder material 34-36%, carbonic acidCalcium 13%, magnesium carbonate 12%, bentonite 11-13%, hydroxyethylcellulose 2.4-2.6%, white glue with vinyl 3.8-4.2%Water composition with surplus.
Preferred described coating is made up of following component by weight percentage: straw powder material 35%, calcium carbonate13%, the water group of magnesium carbonate 12%, bentonite 12%, hydroxyethylcellulose 2.5%, white glue with vinyl 4.0% and surplusBecome.
Described calcium carbonate, magnesium carbonate, bentonite, hydroxyethylcellulose and white glue with vinyl are technical grade.
The beneficial effect of the prepared coating of the present invention is:
1. creationaryly in coating, add reproducible biomaterial: straw powder material, it soaks through zinc peroxideSterilization and anticorrosion after bubble and after high-temperature process, can meet user demand, and nontoxic, and addTo can moisture absorption protection against the tide after in coating.
In material therefor except on a small quantity as the hydroxyethylcellulose of thickener with as the white glue with vinyl of bonding agentOutward, the zinc oxide of calcium carbonate, magnesium carbonate and bentonite and immersion use is the nothing of nontoxic pollution-freeMachine material, and stalk powder belongs to biological recyclable materials, therefore prepared coating environmental protection.
3. because adopted raw material sources are extensive, with low cost, particularly reproducible straw powder material whereinOccupy larger proportion, therefore significantly reduce the cost of coating, tool is calculated its cost and is only equivalent to phenylpropyl alcoholThe 1/3-1/5 of the generic latex paints such as emulsion paint, has been equivalent to add functional additive coating1/8-1/10. Therefore, even rural area and economic backward area also can be born and make completelyUse this coating.
