Abstract
The invention relates to a natural mixture dry powder paint for external walls and a preparation method thereof. The natural mixture dry powder paint for external walls is characterized by comprising the following components in percentage by weight: 30-65% of white silicate clinker, 20-50% of white stone powder, 3-5% of plaster, 5-10% of calcium silicate, assistants, 2-5% of calcium lignosulphonate,. The materials are ground to 400-1200 meshes and the dry powder package is carried out to obtain the finished product. Production and use of the paint solves the defect that the solvent-type paint uses massive gelatine powder so that organic pollution gases are discharged to the atmospheric environment, thereby playing an important role in protecting atmospheric environment.
Description
Technical field:
The present invention relates to a kind of natural mixture dry powder paint for coated building exterior wall or concrete base layer.
Background technology:
Current building constructions,, all there are two large shortcomings in the solvent based coating that exterior wall is used, the one, coating and cement basic layer bonding force are low, smoothness is poor, need to be in cement wall basic unit claircolle or priming paint; And poor durability, easily cracking, foaming shedding can not directly spray in cement concrete basic unit; The 2nd, the soluble gum compound using in coating, increases the discharge of VOC amount, and pollutant atmosphere, brings harm to HUMAN HEALTH.For the above-mentioned shortcoming development and production that exist in current coating natural mixture dry powder paint for external walls.
Summary of the invention:
The object of the invention is in order to provide one to have with cement wall basal plane smooth smooth with regard to good bond without putty, and coating does not ftracture, does not come off, waterproof, anticorrosion, alkaline-resisting, resistance toly scrub, fire-resistant, sterilization, tasteless, bright, tool is ornamental, without discharge, natural environmental-protective and cheap natural mixture dry powder paint for external walls.
Main technical schemes of the present invention is: the composition of this natural mixture dry powder paint for external walls is white portland grog 30-50% (weight ratio), active silicic acid dicalcium 5-10% (weight), white stone powder 30-40% (weight ratio), lime (light calcium carbonate) 5-10% (weight ratio), barium sulfate 2-5% (weight ratio), wilkinite 2-4% (weight ratio), calcium lignin sulphonate 1-2% (weight ratio), gypsum 3-8% (weight ratio), Cornstarch 5-8% (weight ratio).
Natural mixture dry powder paint for external walls of the present invention is mainly made by portland cement clinker, there is higher strength ratio, in conjunction with being aided with again auxiliary agent, through grinding combination, there is stronger bonding force with stone flour, (silica powder) lime (light calcium carbonate).Particularly clear-water concrete and various concrete construction wall face, its sticking power is higher than the bonding standard several times of solvent reducible coatings, so need not criticize putty and prime before spraying this coating.Direct spraying construction, general coat-thickness is 2-4mm, needs thickness according to body of wall, also can, lower than below 2mm, can save Master Cost.The raw material that this coating adopts belongs to pure natural inorganic mineral powder, and its auxiliary agent not only can also can activate the silicate ion in raw material by diminishing, strengthens bounding force, ensure that this coating does not ftracture, do not come off, waterproof, anticorrosion, alkaline-resisting, fire prevention, without discharge, environmental protection.Has the ratio of performance to price.
The production process of this coating is: raw material white portland grog, gypsum, barium sulfate, calcium lignin sulphonate, Cornstarch are added in special shredder in proportion, be ground to 500-1200 order, again white stone powder, lime, Peng Run soil are ground to 350-500 order, component after binomial is ground adds defoamer, drop into after stirrer mixing, by finished product coating dry powder package, sealing, warehouse-in, that is: finished product coating.When construction, dry powder paint is added water, spraying after stirring.Wherein add water how many by construction thickness requirement.General water (weight ratio) 10: 6.This coating needs color preparation, and also available greywater mud portland cement clinker makes, and method is the same.
Embodiment:
Below by specific embodiment, the present invention is described in further detail.
Embodiment mono-:
The coating of this enforcement consists of white portland grog 35% (weight), barium sulfate 5% (weight), gypsum 5% (weight), Cornstarch 5% (weight), calcium lignin sulphonate 2% (weight), drop in special shredder, grind 650 orders again by white stone powder 45% (weight), lime (calcium carbonate) 10% (weight), active silicic acid dicalcium 5-10% (weight), Peng Run soil 5% (weight ratio), is ground to 400 orders separately, by the component mixing and stirring after grinding.Result of use is good, hangs in vain evenly light.
Embodiment bis-:
By example one component, in disposable input shredder, break-in 400 orders, mixing and stirring.
Through using, effect has de-white, foaming phenomenon.
Embodiment tri-:
The coating of the present embodiment consists of white portland grog 45% (weight), gypsum 5% (weight), calcium lignin sulphonate 3% (weight), active silicic acid dicalcium 5-10% (weight), drops in shredder in proportion, be milled to 1200 orders, again by white stone powder 30% (weight), Peng Run soil 5% (weight), lime 10% (weight), drop into another shredder by composition, be milled to 500 orders.By the component after binomial mill, be fed in stirrer and mix.
Through using, whiteness is example one dimness, and when use, example one adds 1/3 than water, and sticking power is same.
Embodiment tetra-:
The coating of the present embodiment consists of white portland grog 45% (weight ratio), gypsum 5% (weight ratio), calcium lignin sulphonate 3% (weight ratio), white stone powder 55% (weight ratio), each component is dropped in shredder, be milled to 500 orders.Stir.
Through result of use lower than example one.
Embodiment five:
The coating of the present embodiment consists of the cement clinker 30% (weight) of silicate, white stone powder 55% (weight), gypsum 5% (weight), active silicic acid dicalcium 10% (weight) barium sulfate 5% (weight), above composition is dropped into shredder and grind 500 orders, mix.Through using, effect is good.
