Description
Technical field
The invention belongs to technical field of paint preparation, it relates to a kind of building coating, more specifically relate to a kind of aqueous elastic exterior coating and its preparation method, be mainly used in building external paint.
Background technology
The most of buildings of current China take cement sand plaster as basic unit. But the natural characteristics due to cement-based material, when being subject to the such environmental effects such as temperature variation, alternation of wetting and drying, freeze-thaw cycle, often can produce crack, if its surface is decorated with common exterior coating, then coating can be caused also to produce cracking along with the crackle generation of basic unit and expansion; Along with gathering of time lengthening and above-mentioned destructive factor, crack can be strengthened further, deepen, and is had a negative impact by buildings and even endangers, and such as, when being subject to moisture attack, moisture can infiltrate in crack and internally permeate further; Except making crack expand further because of alternation of wetting and drying effect, also may cause inside concrete steel bar corrosion, even affect the using function of buildings, for another example, when being subject in air the sour gas such as carbonic acid gas and other corrosive gases corrodes, coating, internal water cement mortar and concrete can be produced corrosion by these corrosive gasess, make concrete carbonization, it is also possible to have influence on inside configuration reinforcing bar. At present, building surface crack is considered as the common fault of buildings and be caused extensive concern on building circle. Therefore, develop a kind of for the protection of with the thick-layer flexible paint keeping concrete exterior wall outward appearance, meaning and act on great.
Summary of the invention
It is an object of the invention to for above-mentioned prior art Problems existing and defect, it is provided that a kind of aqueous elastic exterior coating and its preparation method.
The coating of the present invention is except having required decorative effect, moreover it is possible to hides the capillary fracture of body of wall, prevents wall leakage and prevent concrete carbonization. Owing to concrete exterior wall can expand along with the change of envrionment temperature and shrink; the aqueous elastic exterior coating of the present invention also can expand along with this kind of body of wall and shrink and stretch and shrink; thus hide existing and potential distress in concrete; concrete construction can be protected to corrode from wind and rain, acid rain and frost, and the outward appearance of concrete construction and the integrity of internal structure can be protected. Coating is while having excellent unit elongation, it is also possible to repeatedly stretches and restores, covers crackle effectively lastingly.
It is good that the coating of the present invention has high-weatherability, high resistance to chemicals corrodibility, water tolerance, scrub resistance and artificial ageing resistance, has expressive force and enriches, and stereoscopic sensation is strong, snappiness, plasticity-is extremely strong, strong adhesion, acid and alkali-resistance, do not fade, not playing skin, do not ftracture, maintenance is heavily coated with the features such as easy, the favor being more and more subject to user, has good promotional value and development space.
