Abstract
The present invention is the formula and preparation of uvioresistant paint as building repairing material. The formula consists of base emulsion, pigment, water and assistants in certain weight proportion. The base emulsion is BC-02 emulsion or mixed emulsion of BC-02 and potassium silicate; the assistants include filming assistant, dispersant, densifying agent, and defoaming agent, leveling agent, antimildew agent and preservative; and the pigment includes titanium white powder, light calcium carbonate and talcum powder. The uvioresistant paint is prepared through mixing the said components and adding ultraviolet ray absorbent or ultraviolet ray shielding agent. The uvioresistant paint, test shows, has very high ultraviolet ray shading capacity.
Description
1, technical field.The present invention belongs to prevent that building repairing composite material is because of uviolizing aged formulation for coating material and making.
2, background technology.Traditional building repairing has Steel Concrete to thicken method, external prestressing method, steel plate bonding method etc.More and more be subjected to the welcome of people's door surplus in the of nearly 10 year with composite material reinforced reparation buildings, this not only itself has advantages such as lightweight, high strength, anticorrosive, antifatigue, construction be simple because of her; But also since compare with traditional method in this way have that speed of application is fast, cost is low, efficient is high, execution conditions require lowly, repair complex-shaped job facilities even small space also can construct, can reinforce, and help intellectuality.
So-called is that composite fiber fabric (cloth) is adhered to building surface with " adhesives " with composite material reinforced reparation buildings technology, thereby reaches the purpose that structural strengthening is repaired.
In practical engineering application, the principal element that the life-span is repaired in influence is buildings that matrix material is repaired load of bearing and the environment of repairing with the matrix material use, as water enchroachment (invasion), temperature (high temperature, low temperature), humidity and uviolizing etc., these environment can cause repairing aging with matrix material, cause the life-span to be gone down.
How to address this problem, normally add one deck special coating,, then will develop the coating of protectiving ultraviolet as solving the problem of antiultraviolet irradiation in its outside.Because not long duration of service, and be again a novel effective means with composite material reinforced repairing buildings, at ultraviolet ray ageing to matrix material/concrete bonding Effect on Performance and resist these aged coating and yet there are no research report so far.
3, summary of the invention.The present invention is the ultraviolet protection coating that a kind of building repairing composite material is used.It is made up of matrix emulsion and pigment, water, auxiliary agent, and wherein the matrix emulsion has two kinds to be BC-02 latex and BC-02
Latex and potassium silicate emulsion; Pigment has titanium dioxide, light calcium carbonate and talcum powder; Auxiliary agent comprises film coalescence aid, dispersion agent, thickening material, cuts infusion, leveling auxiliary agent, mould inhibitor, sanitas, UV light absorber or ultraviolet screening agent.Wherein UV light absorber is the various combination of UV-P, UV-327, UV-531, BAD etc., and ultraviolet screening agent is by ZnO, AI
