Description
Technical field
The present invention relates to a kind of Self-leveling inorganic powder indoor architectural paints and preparation methods, belong to indoor architectural paints skill
Art field.
Background technique
For the strategic objective for carrying out nation-building resource-conserving and environment-friendly society, building materials are gradually by high energy
Consumption, high pollution, maximum discharge are to resource-effective, environmental-friendly and be conducive to the development in healthy ecology health direction.It is well known that applying
Expect that industry is a unique raw material intensity manufacturing, most of organic coatings have used some more in process of production
To human body and the harmful raw material of environment, harmful waste water and exhaust gas can be given off in production and work progress, according to investigations, at present
Dazzling emulsion paint and water paint are more or less all containing harmful substances such as formaldehyde, VOC in the market.Even often at present
Interior decoration water paint emulsion paint, due to raw material from pure C latex, styrene-acrylic emulsion, acrylate and vinyl acetate emulsion, vinyl emulsion,
Fluorine carbon emulsion etc., in addition dispersing agent, defoaming agent, anti-icing fluid etc., the harmful substances such as formaldehyde, VOC are inevitable.
In order to pursue more environmentally friendly indoor decorative paint, currently reported high solid powder coating, solventless coatings, powder
Last coating, water paint and photocureable coating etc. provide strong due to using water as solvent and solvent-free for environmental protection coating material development
Big technical support.But according to practical application, it is main that existing environmental protection coating material mostly uses organic film former to form a film as coating
Raw material, if Chinese invention patent publication number CN105462303A discloses inorganic dry powder painting, by weight by following components
Composition: 1~2 part of N-Methyl pyrrolidone, 2.8 parts of gas-phase silicas, 1.8 parts of alkylnaphthalene sulfonates, 3.1 parts of three ethoxies of vinyl
Base silane, 9.7 parts of calcined kaolins, 8.9 parts of latex powders, 6.7 parts of sepiolite clays, 16.8 parts of calcium carbonate, 72.3 parts of white cements.It can
See, which is using calcined kaolin, sepiolite, calcium carbonate, white cement as inorganic material, using latex powder as film forming matter.Although white
Cement can also with film-forming, but in order to reach it is good film forming still use latex powder, do not accomplish completely it is inorganic at
Film.
It is existing at present that inorganic silicic acid salt, inorganic phosphate salt, silica solution class conduct are such as used using inorganic matter completely
Inorganic film forming curing agent realizes complete inorganic dry powder painting, realizes complete zero voc.This inorganic coating is not only environmentally friendly, and
Harmful substance is also seldom discharged in the production and processing of its raw material；For having in building coating, fire prevention, mould proof, durability is special simultaneously
Point.
Application No. is 201710737080.2 patents of invention to disclose aqueous inorganic zinc-rich anti-corrosive paint and its preparation side
Method, the coating are made of component A well prepared in advance and component B with the mass ratio mixing of 1:2~4, in which: the component A
For aqueous alkali metal silicates solution, component A includes: aqueous silicic acid sodium 15%~25%, aqueous silicic acid potassium by percentage to the quality
15%~25%, aqueous silicic acid lithium 15%~25%, water nano silica solution 15%~25% and deionized water 15%~25%；Component
B is powder mixture, and component B includes: zinc powder 85 ~ 90%, quartz sand powder 6 ~ 10% and filler 3 ~ 5% by percentage to the quality.

It can spraying application after filter.The product itself is free of any organic matter, VOCs zero, and simple production process conveniently, is not required to add
Complicated technologies, environmental protection and energy saving, the uses such as pressure are safe.
However, being formed a film in view of inorganic dry powder painting using inorganic bond, the characteristics of due to inorganic matter, form a film more rough, color
The color uniformity is poor, and levelability is poor after brushing, and coating is not fine and smooth, using limited in fine finishing.Especially add in construction
Enter water use, dispersing uniformity is difficult to control, and obtained coating is rough, increases the difficulty and homogeneity of construction.
Well known, inorganic dry powder painting is based on inorganic matter, and film forming matter therein is inorganic adhesive, therefore when in use
It needs to dissolve inorganic adhesive, and bonds inorganic matter to form coating, however since inorganic adhesive is bonded as single
Bonding between grain is different from organic latex liquid and forms a film, and inorganic adhesive is difficult to form continuous fine and smooth film.
