Description
Technical field
The present invention relates to inorganic coating agent composition and preparation method thereof, in more detail, relates to improve anti-cracking
Property, water resistance, stain resistance, abrasion performance, resistance to tack, water proofing property, scoring resistance, cold resistance, corrosion resistance, chemical resistance
And/or the environment friendly inorganic class coating agent composition of durability etc., specifically, include the environment-protection functional of inorganic mixed type without
Machine class coating agent composition and preparation method thereof.
Background technology
For coating fluid composition, before for a long time developed with multiple use and a variety of form.
Here, the coating fluid composition is also known as coating (paint), its purposes is coating and is attached to a variety of objects
Face, such as the subject surface for the product being made up of metal, ceramic tile, timber or concrete etc., so as to protect attachment surface from from
External environment condition such as polluted water it is physical/chemically impact.
Especially, it by conventional plastic resin emulsion or emulsion acrylic resin etc. using synthetic resin is main that water paint, which is,
The coating fluid composition of composition is applied on cement works thing, but film is easy to depart from or faded, and the life-span is shorter.
In addition, with the coating that synthetic resin is made because its various volatile ingredient contained can be sent out for a long time after application
Dissipate and pollute ambient air, the shortcomings that presence not environmentally.
Especially, further deepen to can solve the problem that described ask, it is necessary to develop under the present situation of the Environment Regulation of volatile substance
Inscribe the high functionalized coating of point or natural feature of environmental protection coating.
Especially, with the raising of nearest quality of life, the attention rate of environment is continuously increased, emphasized to the clean of room air
Net concept, while demonstrate various indoor hardware fittings and can produce harmful material, " the Sick House in order to solve
The social concern of (pathogenic room) syndrome ", it is desirable to the feature of environmental protection of various finishing materials and harmless coating fluid composition
Product.
Most of construction material that interior uses includes harmful chemical.Especially, it is contemplated that a large amount of productions and expense side
Face, the dosage of the construction material comprising chemical substance are being continuously increased, and IAQ becomes worse and worse.
Also, for the concrete or mortar being coated with, it is divided into dry process and damp process to being coated to by film layer, dry process is
It is being polyurethane series, epoxy rubber asphalt of the surface coating solvent type of concrete or mortar etc. by film layer, or it is overlapping
The method of stickup, processability is good, and adhesiveness, oxygen are outstanding through repellence, screening flame and pliability.If but by film layer
Clean conditions, smoothness, drying regime etc. are bad, can cause the stickup between surface bad after construction, produce protuberance, dissociate now
As the organic water for forming film easily goes bad because of ultraviolet, produces caused by absorbing moisture deterioration etc., durability and heat-resisting
Property can reduce.
Especially, if the concrete or mortar are coated on into outdoor, easily produced because of acid rain neutralization, corrosion and/or
The problem of aging.
In addition, recently, the trend of construction material is presented hommization, has more new functions, and presentation is multi-functional, and needs
The material of its efficiency can be maximized.
Especially, the situation of coating agent composition for building is modernization and hommization key element according to building, in its face
Color, taste, to the helpfulness (antibacterial, deodorization, far infrared, anion etc.) of human body etc. the physical property to be looked for novelty.
That is, in addition to outer wall of the building defencive function and the function of appearance modification that conventional coating agent composition has,
Also need to multifunctionality tasteless, environmentally friendly, beneficial to human body.
Especially, domestic paint industry occupies the greatest ring of domestic VOC (VOCs) total release 50%
Border pollutional load, it is one of representative public hazards industry.
Therefore, in order to solve described problem, Korean Patent, which discloses, discloses reduction newly in No. 2012-0021967
Room syndrome, there is the water-based calcicoater composition of antibacterial and mould proof characteristic, Korean Patent Registration 10-0662510
A kind of coating composition using aqueous polyurethane adhesive is also disclosed that in number, including：Add water in aqueous prepolymer dispersions
Afterwards, using distillation under vacuum, content of volatile organic compound is adjusted to below 5g/L step.
In addition, as the coating using inorganic constituents, alkali silicate is resolvability silicate, because of the strong alkali gold of hydrophily
Belong to and the smears with outstanding cohesive force and dispersion force, but for needing the field of water resistance, it, which is applicable, has limitation.
Therefore, in order to improve the water resistance of the coating using the inorganic constituents, prepared by the mol ratio that can improve silicate
Coating composition, but the stability of solution can not be met, gel phenomenon can be produced.
If also, alkoxy silane is added to Adhesion Promotor, water resistance can be greatly improved, available is a variety of sides
Formula, but the problem of curability is low be present.
Therefore, self-cleaning to the concrete permeability surface protecting material using silane and silicate and durable has been carried out
The research of performance, but for the lasting effect of water resistance part and self-cleaning, it is necessary to additional research.
Accordingly, it is necessary to one kind be easy to permeate and be coated on concrete construction, glass etc., can effectively protect because of air
Acidification and and carbon dioxide pollution and neutralisation concrete construction, there is the corrosion for preventing metallics and strengthen timber
Deng antiseptic effect, promote it is heat-insulated and substitute thermal isolation film economic and environment-friendly property inorganic smears.
The content of the invention
(technical problems to be solved)

Wherein, be natural mineral water state because carborundum is not present, need are artificial synthesized, chemical stability under high temperature and anti-corrosion
Property protrude, there is higher hardness.
This carborundum floats on the surface to form film in the drying process with aluminum oxide microgranule powder, is formed thin
Close and high hardness film, except that can prevent vapor and other gases, penetration by liquid, also there is prominent moisture-proof, resistance to
Long property, weatherability, impact resistance, resistance to chemical reagents, application face be capable of reflecting light and from UV protection film.
Also, because of the heat endurance that carborundum and aluminum oxide protrude, the rising of adherend temperature can be prevented, reduces coagulation
Contraction, the expansion of soil, prevent neutralisation/chlorination of resin, the long-term durability for maintaining application.
