Abstract
The utility model relates to a protective coating structure for a concrete joint, which comprises a silicane steeped waterproof layer, a silicane terminated polyester sealant elastic layer and a silicane terminated polyester flexible paint layer, wherein the silicane terminated polyester flexible paint layer is arranged on the surface of concrete; the triangular silicane terminated polyester sealant elastic layer and the triangular-frame-shaped silicane steeped waterproof layer are sequentially arranged from the silicane terminated polyester flexible paint layer inwards; and a corner of the silicane steeped waterproof layer is located on a concrete joint line. The protective coating structure can ensure long water resistance at the concrete joint, and bear displacement caused by thermal expansion and cold contraction of the concrete; bonding performances among various materials are excellent; a whole coating is more durable, and excellent in appearance effect; the protective coating outside the concrete can be maintenance-free for 30 years; and the protective coating structure is green, environment-friendly, simple and convenient to construct, and appropriate for extensive popularization.
Description
Technical field
The utility model relates to a kind of coating structure for the building concrete protection, especially can realize a kind of concrete joint protective coating structure of concrete seam long-acting water-proof.
Background technology
In recent years, country greatly develops infrastructure construction, the large-sized concrete building is more and more, the concrete of heavy construction all needs to use mould piecemeal, segmentation to build to form, between every block of concrete of building, seam is arranged all, in concrete protection, the protection of seam never obtains enough attention.Traditional means of defence is to use the floating seam of epoxy putty, more once brushes epoxy primer, intermediate coat, polyurethane finish or fluorine carbon finishing paint in the above.Along with passage of time, the shortcoming of this coating comes out gradually.Because there be certain expanding with heat and contract with cold in concrete itself, seam crossing is a stress relief point of concrete heat expansion shrinkage, and the epoxy putty that is applied in seam crossing is without any elasticity, so embrittlement can occur in epoxy putty very soon, directly cause the cracking of external paint coating, and then cause corrosive medium to enter inside concrete, corrosion concrete from seam crossing protective coating destruction.
The utility model content
The problem of embrittlement easily occurs in order to overcome existing concrete protection coating, the utility model provides a kind of concrete joint protective coating structure, this protective coating structure can guarantee the waterproof that concrete seam is long-acting, can bear again the displacement that the shrinkage of concrete heat expansion is introduced, and between each material, bond performance is good simultaneously, whole coating is durable good, appearance effect is good, can guarantee that concrete exterior protection coating 30 years is non-maintaining, and environmental protection, easy construction, suitable spread.
The technical scheme that its technical problem that solves the utility model adopts is: this concrete joint protective coating structure comprises impregnating with silane waterproofing course, Silante terminated polyether seal glue elastic layer and Silante terminated polyethers flexible paint layer; Described Silante terminated polyethers flexible paint layer is arranged at concrete surface, Silante terminated polyethers flexible paint layer inwardly is followed successively by the Silante terminated polyether seal glue elastic layer of triangle and the impregnating with silane waterproofing course of triangle frame shape, and an angle of impregnating with silane waterproofing course is positioned on the concrete joint suture.
The material of described impregnating with silane waterproofing course is isobutyl group trimethoxy silane or isobutyl triethoxy silane or iso-octyl alkene trimethoxy silane or iso-octyl alkene triethoxysilane.
Described Silante terminated polyether seal glue elastic layer is used silane end capped polyether fluid sealant and is prepared from, and sealing glue can fill up seam, and coheres well with concrete, 100% solid content, the fluid sealant volume can not shrink, and elastic performance is good, and elongation at break is 400%-600%.
Described Silante terminated polyethers flexible paint layer is to be prepared from by Silante terminated polyethers flexible paint, and its elongation at break is 100%-300%, is particularly suitable for outdoor existence and expands with heat and contract with cold and cause the concrete surface of displacement.
When this protective coating is set, at first shaping is cut at concrete joint suture place, the concrete joint suture is shaped to the isosceles triangle shape concrete pit of dark 30mm, wide 30mm, and clean out the floating ash in surface; Brush twice impregnating with silane waterproofing course on the surface of concrete pit, requiring use amount is 400g/m2, and making length of penetration is 3mm; After 48 hours, then at the Silante terminated polyethers elastic sealant of impregnating with silane waterproofing course surface application, make fluid sealant fill up the concrete joint slot, and floating; After 72 hours, spraying silane end capped polyether flexible paint on glue-line, coating thickness is 800-1000 μ m.
The beneficial effects of the utility model are, this protective coating structure can guarantee the waterproof that concrete seam is long-acting, can bear again the displacement that the shrinkage of concrete heat expansion is introduced, between each material, bond performance is good simultaneously, and whole coating is durable good, and appearance effect is good, can guarantee that concrete exterior protection coating 30 years is non-maintaining, and environmental protection, easy construction, suitable spread.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
