Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
The epoxy resin repairing process of the bucket arch mainly comprises the following steps:
step one, preparing an epoxy resin mixture for repairing, wherein the epoxy resin mixture contains bisphenol A type epoxy resin.
And step two, filling the epoxy resin mixture in the damaged part of the bracket to be repaired, so that the external contour of the bracket filled with the epoxy resin mixture is consistent with the original external contour of the bracket.
About step one
The epoxy resin mixture may also contain modifiers, such as: polyamide resin, phenolic resin, isocyanate and pigment, or a mixture of at least two of the above. Therefore, the connectivity, the high temperature resistance and the corrosion and insulation performance of the resin are selectively improved according to the environment condition of the building, or the color is selected according to the requirement of the repair work on the identifiability. The epoxy resin mixture can also contain a curing agent. The choice of curing agent is related to the curing temperature of the epoxy resin, with polyamines and polythioamines being common for curing at common temperatures.
Detailed description of the preferred embodiment 1
The epoxy resin mixture is composed of only a bisphenol A epoxy resin reinforcing agent. The curing agent in this case is preferably a light curing agent, particularly a light curing agent at room temperature. And the epoxy resin mixture is stored in the shading bottle, so that the epoxy resin mixture is prevented from being cured in advance. The bisphenol A type epoxy resin and the curing agent comprise the following components in percentage by mass: 83%: 17 percent. The curing agent is higher in price at present, and the component has the lowest curing agent content under the condition that the curing speed is ensured to be within an acceptable range, so that the cost of a finished product can be greatly reduced, and the process is favorable for popularization.
Specific example 2
The epoxy resin mixture is prepared by mixing bisphenol A type epoxy resin and polyamide resin, and the mass percentages of the bisphenol A type epoxy resin and the polyamide resin are as follows: 45%: and 55 percent. The cured epoxy resin has good physical and chemical properties, excellent bonding strength to the surfaces of metal and nonmetal materials, good dielectric property, small set shrinkage rate, good product dimensional stability, high hardness, good flexibility, stability to alkali and most solvents, independent packaging of the product, and mixing on construction sites after transportation. And in the second step, after the epoxy resin mixture and the curing agent are mixed, the mixture mixed with the curing agent is filled in the damaged part of the bucket arch to be repaired, so that the mixture is prevented from being cured in advance.
Specific example 3
The epoxy resin mixture is prepared by mixing bisphenol A epoxy resin, polyamide resin, phenolic resin and isocyanate, wherein the bisphenol A epoxy resin, the polyamide resin, the phenolic resin and the isocyanate are in percentage by mass: 50%: 30%: 10%: 10 percent. The phenolic resin and isocyanate mixture in the mixture components can further increase the dried arbitrary property and water-repellent property of the mixture, and the mixture has darker color, so the material is more suitable for being used as a repairing material of a dark bracket component, such as red iron oxide and a black component, and the product is independently packaged and mixed on a construction site after transportation. And in the second step, after the epoxy resin mixture and the curing agent are mixed, the mixture mixed with the curing agent is filled in the damaged part of the bucket arch to be repaired, so that the mixture is prevented from being cured in advance.
Relating to step two
The epoxy resin mixture can be directly extruded into the cracks of the bracket arch, and the cracks can be filled and leveled. And then, molding the outer surface of the repair structure formed by the epoxy resin mixed material once every ten minutes, and finally enabling the shape and the outer contour of the repaired bucket arch to be consistent with the shape and the outer contour of the originally designed bucket arch.
Or, fixing a material injection section on the bucket arch to be repaired, wherein the material injection section is provided with a material injection port, the material injection port is communicated with the cavity, the cavity is communicated with the damaged part of the bucket arch to be repaired, and the epoxy resin mixture enters the damaged part of the bucket arch to be repaired through the material injection port and the cavity; and removing the material injection section after the epoxy resin mixture entering the damaged part of the bucket arch to be repaired is dried. With the method, the epoxy resin mixture can be injected more conveniently. Moreover, the profile of the cavity of the injection section is consistent with the original external profile of the bucket arch. Under the constraint of the cavity, the repair structure is connected with the bucket arch to be repaired more firmly, and the shape and the outer contour of the repaired bucket arch are consistent with those of the original bucket arch. Compared with the manual molding method, the method has lower requirements on constructors and better consistency after completion. The material injection section bar can be made of organic glass material, in particular transparent organic glass. The organic glass has smooth surface, and can ensure more epoxy resin mixed materials to flow into gaps of the bracket to be repaired. And transparent organic glass makes things convenient for constructor to see through organic glass and observe the solidification condition of epoxy mixed material. The bucket arch component has more modeling inflection, and in some local repair works, organic glass can not satisfy the condition that the modeling was sought, and at this moment, notes material section bar can also be glass fiber woven cloth or other soft water-proof materials that the plasticity is stronger. The material injection section bar is preferably of the following structure: the material injection section comprises an upper horn mouth positioned above, a connecting part positioned in the middle and a lower horn mouth positioned below, wherein the inner diameter of the upper horn mouth is gradually increased from top to bottom, the upper horn mouth is used as a material injection port, the inner contour of the lower horn mouth is consistent with the contour of the original design of the bucket arch to be repaired, the lower horn mouth is fixed on the bucket arch to be repaired, a relatively closed cavity is defined by the lower horn mouth and the damaged part of the bucket arch to be repaired, and the cavity is used as a cavity of the material injection section. The connecting portion is provided with a first through hole and a second through hole, the upper end opening of the first through hole is arranged at the lower end opening of the upper horn mouth, the upper end opening of the second through hole is arranged at the upper end opening of the upper horn mouth, and the lower end openings of the first through hole and the second through hole are arranged at the upper end opening of the lower horn mouth. When the mold is used, the epoxy resin mixed material is injected downwards by utilizing the first through hole, and air in the cavity is exhausted by utilizing the second through hole. Meanwhile, when the material injection section bar is made of an opaque material, whether the cavity is filled with the epoxy resin mixed material or not can be judged by observing whether the upper port of the second through hole is filled with the epoxy resin mixed material or not. The side wall of the first through hole can be provided with a groove with an opening facing to the central axis of the first through hole, and the extending direction of the groove is the same as the extending direction of the first through hole. The groove can be used for improving the flowing condition of the epoxy resin mixed material in the first through hole, so that the flowing is more gentle and the foaming is less likely to occur. The inner diameter of the first through hole preferably becomes abruptly smaller at the lower port. Therefore, the connection between the repair structure and the residual epoxy resin mixture in the first through hole is cut off in a mode of breaking the part, and the injection section bar is convenient to remove. The inner diameters of the first through hole and the second through hole can be gradually increased from top to bottom, and the injection section bar can be removed in a mode that epoxy resin in the first through hole and the second through hole is pulled out from the lower side. The injection-molded parts are preferably connected to the bucket arches to be repaired by means of an adhesive. Or may be tied together by a rope.
Bucket arch for repair
The bucket arches to be repaired may be, and preferably are, those with superficial damage. Namely, the surface of the bucket arch component is partially damaged, mildewed, cracked, damaged and the like at one or more parts due to the stripping of the paint finish surface layer, and the depth of the bucket arch component is not more than 10% of the total length of the component.
When a plurality of damaged positions exist in the bucket arch to be repaired, one damaged position and one damaged position can be repaired in turn. And a drainage groove can be formed in the inner surface of the lower horn mouth, and the epoxy resin mixture is introduced into each damaged position through the drainage groove. The drainage groove is communicated with the lower port of the first through hole. If the damage depth of the bucket arch to be repaired exceeds 10 percent of the total length of the component, the support can be filled in the damaged position, and then the process of the invention is utilized to repair. So as to avoid the epoxy resin mixture from occupying too large proportion. The filled support is preferably glass fibre. The glass fiber plays a role in supporting, draining and connecting the epoxy resin mixture, so that the repaired structure is not easy to collapse and is removed more cleanly when being removed.
