Description
Technical field
The present invention relates to a kind of process units of Dry Powder Architectural Paint, relate in particular to a kind of can continuous, high production capacity production the device of white Dry Powder Architectural Paint base-material and use described device to produce the method for white Dry Powder Architectural Paint base-material.
Background technology
Building coating mainly refers to have decoration functions, defencive function and inhabitation improvement in performance function for the coating on external wall, interior wall, ceiling, ground etc.Organic volatile, organic solvent and the heavy metals etc. such as the benzene class material in the early stage coating, formaldehyde bring severe contamination to environment and the mankind, have the risk of pollution from producing to each link of using.The attention to polluting along with the progress of technology and people, coatings industry have entered " water paint " epoch from " oil paint " epoch.
Building coating is take water paint as main at present, and water paint is the coating take water as decentralized medium, comprises aqueous emulsion and aqueous solution type coating.The content of harmful substance is lower than oil paint in the water paint, is satisfying under the prerequisite of using function, than more environmental protection of oil paint.Comprise the water up to 35 ~ 55% during but water paint forms, this needs cost a large amount of human and material resources and financial resources for packing and the transportation of water paint; Water paint shelf-life and storage life are short, in order to solve the aqueous architectural coating storage stability, the phenomenons such as layering, thickening do not occur between the storage life namely, also need very high cost and special technology.And for interior space sealing or semiclosed environment, people pursue more that the technology exploration of environmental protection coating material never stopped.
Germany Wacker Chemical Co.,Ltd (Wacker Chemie AG) develops redispersable latex powder, coating dry powder is changed into be possible.Dry powder paint generally is that emulsion is become powder through the special process drying, has changed production and banking system, and production cost reduces, packing and convenient transportation, safety, storage life and long shelf-life; During use and solvent be made into alcohol radical or water based paint or quick drying paint, strong adaptability, easy to use; And saved the chemical assistant that must add in the general coating, not only solved problem of environmental pollution, and economized on resources, thereby be widely used and develop.The dry powder of coating (especially interior wall coating) has become the important new technology of coating environmental protection, and is subject to the extensive attention of industry.
Such as Chinese patent CN102617103A(application number 201110446739.1) a kind of inorganic powder building coating and production method thereof that does not contain curing agent disclosed, Chinese patent CN102617102A(application number 201110446699.0) a kind of inorganic powder building coating and production method thereof are disclosed, Chinese patent CN102617104A(application number 201110446747.6) disclose a kind of inorganic powder sand textured coating and production method thereof, above-mentioned dry powder paint technology further is reduced to a new historical level with the limits of harmful substances of dry powder paint.
The production of existing dry powder-shaped building material product can both be embodied as the microcomputer automatic control of complete equipment, and automatic gauge, mixing and automatic packing, be equipped with cleaner, in the standardization industrial premises, install, can make in the workshop clean and tidy totally, labour intensity is low, production capacity is large.Those skilled in the art will know that, except the coating base component, coating comprises also that generally pigment is to obtain required color, but because the particularity of dry powder paint product is (such as many color variety, color homogeneity requires high, that raw material types changes is many, difference waits greatly), the dry powder paint of different batches is easy to occur the situation of color colour difference.The production technology of existing dry powder paint generally all adopts the batch mixed technology of the package, and marks respectively the difference between different batches, and there are the shortcomings such as production capacity is low, color management is poor in the mode of this batch wrapping.
In order to improve production capacity and to strengthen color management, can adopt white Dry Powder Architectural Paint base-material continuous production processes, then white Dry Powder Architectural Paint base-material is matched colors, this production technology production capacity is large, although but the method has solved the production capacity problem, but the whiteness between batch is variant, thereby the aberration problem of the rear coating that causes matching colors can't be avoided.
