Abstract
The invention provides a production method of dry-mixed facing mortar with controllable whiteness. The whiteness of the designed white mortar is B1; the whiteness B2 of mortar formed by different basic component and aggregate mixtures is tested under the condition of containing no white pigment; the weight W of a white pigment required to be added into the basic component and aggregate mixtures is tested when B2 is adjusted to B1; a relation graph or/and table of B2 and W is/are drawn; basic components and aggregates of the mortar are provided, metered and mixed, and the whiteness B3 of the mixture is tested; and the weight Wt of a white pigment required to be added when B3 is adjusted to B1 is found according to the relation graph or/and table drawn in the step 3, and the white pigment with weight of Wt is added to obtain the white mortar with the required whiteness. According to the invention, after mixing of the basic components, the pigment is added to prepare the white mortar, and the whitenesses of products in all batches are almost kept the same; and in addition, the production quality is controllable and the productivity is increased.
Description
Technical field
The present invention relates to a kind of production method of mortar, relate in particular to a kind of serialization, high production capacity and batch between the basically identical controlled method that is dry mixed facing mortar of production whiteness of whiteness.
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-borne coatings " epoch from " oil paint " epoch.
Building coating is take water-borne coatings as main at present, and water-borne coatings is the coating take water as dispersion medium, comprises water miscible liquid and aqueous solution type coating.The content of objectionable impurities is lower than oil paint in the water-borne coatings, 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-borne coatings forms, this needs cost a large amount of human and material resources and financial resources for packing and the transportation of water-borne coatings; Water-borne coatings quality guaranteed period and shelf lives are short, in order to solve the aqueous architectural coating stability in storage, the phenomenons such as layering, thickening do not occur between the shelf lives 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, shelf lives and long quality-guarantee period; 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 solidifying 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 sandy paint 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 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 dust removal installation, in the stdn 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 singularity 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 technique of existing dry powder paint generally all adopts the batch mixing 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.
The complexion mortar be China from a kind of novel finishing material of external introduction, the colour-change scope is wide, moulding is abundant, is generally made by gelling material, aggregate, filler and additive etc., is used for construction wall surface and ceiling decoration.As mentioned above, this area lacks the controlled production method that is dry mixed facing mortar of a kind of whiteness, so that the production of white mortar is under the prerequisite of accomplishing scale production, and the aberration between reducing batch, thus improve final product quality stability and production capacity.
