Abstract
The invention relates to an ecological shell powder coating, and belongs to the technical field of building materials. The ecological shell powder coating is prepared from the following raw materials in parts by weight: 30-60 parts of shell powder, 30-50 parts of colloidal silica sol powder, 4-7 parts of titanium dioxide, 2-7 parts of zinc oxide, 1-5 parts of a film forming aid and 1-3 parts of an antifoaming agent, wherein the colloidal silica sol powder is water dispersible nanoscale silicon oxide, and the particle size range is within 10-25 micrometers; the shell powder is shell powder subjected to dechlorination, the content of Cl is lower than 6%, and the particle size range is within 10-50 micrometers. Compared with the prior art, the ecological shell powder coating provided by the invention has the advantages as follows: the production cost is extremely low, the cost of the ecological coating is greatly reduced, and a greater price advantage and quality guarantee are achieved; besides, the prepared exterior wall coating has the characteristics of ultraviolet radiation protection, air purification, corrosion resistance, scratch resistance, temperature regulation and control, good stain resistance and the like, the preparation method is simple in preparation processes, environment-friendly and low-carbon, the coating can be used by simply stirring after being added with water during the construction process, therefore the construction is convenient, and nontoxicity and environment friendliness are further achieved.
Description
Technical field
The invention belongs to building material technical field, particularly relate to a kind of shell ecologic coating powder.
Background technology
Existing coating is mainly divided into oil paint and the large class of water-borne coatings two, is applied to the external coating such as body of wall, furniture.The various binding agent of often employing of these coating and stopping composition mix, the base-material major part of this binding agent and stopping composition is poisonous and hazardous Chemicals, especially there is the coating of anticorrosive mildewproof function, the larger chemical substance of toxicity must be used to be effective.This coating can discharge poisonous and harmful element in production and use procedure, will damage human body.
The main component of shell is calcium carbonate and a small amount of chitin element of 95%, and a small amount of trace element, amino acid etc.The top layer of shell is thin and transparent, has the effect preventing carbonic acid from corroding, and the chitin element secreted by mantle edge is formed, and can be used for doing investment precoat; The internal layer of shell is nacreous layer, is built up, have beautiful gloss by the foliated lamellar aragonite (aragonite) of mantle whole surface secretion, can increase with health and thicken, middle level is mainly made up of calcite, and brilliant white, as newly, is applicable to replacing kaolin in coating very much.
Shellfish material is so environmental and ecological, is also applicable to very much making coating, but does not also have a kind of shell that adopts till now to manufacture the wall paint of ecological, environmental protective!
Summary of the invention
In order to overcome above-mentioned shortcoming, the invention provides the shell ecologic coating powder of a kind of pure natural, low cost of manufacture simple to human non-toxic's evil, environmental protection, technique.
The technical solution used in the present invention is to achieve these goals: a kind of shell ecologic coating powder, is made up: oyster shell whiting 30 ~ 60 of the raw material of following weight proportion; Silicon sol powder 30 ~ 50; Titanium dioxide 4 ~ 7; Zinc oxide 2 ~ 7; Film coalescence aid 1 ~ 5; Defoamer 1 ~ 3; Described silicon sol powder is aqueous dispersion type nanoscale silicon, particle size range 10 ~ 25um; Described oyster shell whiting is the oyster shell whiting after de-Cl process, the content of Cl lower than 6%, particle size range 10-50um; Described titanium dioxide is that rutile-type and dichloride in anatase type grade titanium dioxide are mixed according to 1 ~ 4: 1 weight ratio, particle size range 15 ~ 35um; Described zinc oxide is Nano-class zinc oxide, particle size range 10 ~ 30um; Described film coalescence aid is one or more mixtures in propandiol butyl ether, 1-Methoxy-2-propyl acetate, Lauryl Alcohol ester, and purity all >=99%; Described defoamer is that polydimethylsiloxane and metallic soap of stearic acid mix by 2 ~ 5: 1 weight ratio.
The preparation method of shell ecologic coating powder described above, step is as follows: a. produces oyster shell whiting, (1) shell removal of impurities: shell and shell waste material are put in stirrer and stirs, the earth of shell surface, sandstone, metal impurities are removed, then rinses well with clear water; (2), shell is allowanced for bark: the shell after removal of impurities is loaded chase, puts into the pond that water mixes with edible alkali, soak and pull out afterwards for 1 day, place 1 day; Then pour stirrer into stir, rinse with clear water after stirring, dry, the stratum corneum of shell surface can be removed; (3), pulverize: cuticular for removing clean shell is poured in pulverizer, is ground into fine particulate; (4), abrasive dust: the shell being ground into fine particulate is poured in refining mill and grinds, obtained 300 ~ 600 object fine powders; (5), dry: the oyster shell whiting of milled is put in electric oven to dry namely obtain oyster shell whiting; B. silicon sol powder, titanium dioxide, zinc oxide and oyster shell whiting solids mixing is even, carry out high speed dispersion, jitter time is 1.5-2.5h, defoamer and film coalescence aid is added afterwards, is again fully uniformly dispersed and static slaking, obtains product.
Described high speed dispersion refers to that high speed dispersor band dentation dispersion impeller rotates with rotating speed 800-1200r/min.
Compared with prior art, the present invention utilizes oyster shell whiting to make ecologic coating, and production cost is extremely low, greatly reduces the cost of this ecologic coating, possesses larger price advantage and quality guarantee.The features such as obtained exterior coating possesses anti-ultraviolet radiation, purifies air, anticorrosive, anti scuffing, temperature adjustment temperature control, resistance to soiling are good.Preparation method configures technique simply in addition, environmental protection low-carbon (LC).Only need add water in construction process and stir and can use, convenient construction, asepsis environment-protecting.
