Description
Technical field
The present invention relates to treating of wood field, be specifically related to a kind of plank sheathing renovation agent and preparation, using method.
Background technology
Top-grade building, bridge, overpass, tunnel, the cast of culvert concrete at present need to use surface to be covered with the film coated plate of clear water film, and clean water coating plate smooth surface is smooth, and the concrete surface got is not required to do secondary again and scrapes ash and finishing；But film coated plate is wooden structures, construction site uses environment poor, has the situation pounded, touch, draw and film coated plate is damaged to occur unavoidably.Plain form once damaged, cannot use only as general template as clear-water concrete template, and the price of clean water coating plate be higher than general template by about 35%, and this results in unnecessary waste.
It addition, other building template, as bamboo film coated plate, gluing plank sheathing there is problems in that too.When template surface has a small amount of damage, and when not having suitable renovation agent to repair, water is easy for entering in template from there, further speeds up the damage of template.
Summary of the invention
It is desirable to provide a kind of plank sheathing renovation agent and preparation, using method, renovation agent adhesive force is strong, glue performance good for this, can Efficient software patching template wound, it is ensured that template serviceability.
Technical solution of the present invention is as follows: a kind of plank sheathing renovation agent, and its composition is as follows with percentage by weight: epoxy resin 18%-47%, diluent 10%-15%, lignin 20%-30%, wood carbon dust 20%-30%, silica flour 2%-5%, pigment 1%-2%.
Described diluent is acetone or dehydrated alcohol.
Plank sheathing renovation agent of the present invention is prepared via a method which:
A, in the epoxy resin that percentage by weight is 18%-47% add percentage by weight be the diluent of 10%-15%, be stirred；
B, take lignin and wood carbon rolls, cross 180 mesh mesh screens choosings, take lignin that percentage by weight is 20%-30% and add said mixture with the wooden carbon dust that percentage by weight is 20%-30%；
C, add percentage by weight be the silica flour of 2%-5%, percentage by weight be to be stirred after the color of the 1%-2% pigment corresponding with template.
Plank sheathing renovation agent of the present invention, its using method is as follows:
By needing the position repaired to clean out, take appropriate renovation agent, add the firming agent that weight is renovation agent weight 1-2.5 times, be padded to the position needing to repair after uniform stirring, remove the renovation agent that repair place is unnecessary.
Described firming agent is preferably polyamide.
Technical solution of the present invention has the advantage that
1, the lignin in renovation agent formula of the present invention increases its bridging property so that the adhesion between renovation agent and template is the most firm；Wood carbon dust and silica flour then add hardness and the abrasion resistance of renovation agent, it is ensured that repair the use quality of rear pattern plate；
2, renovation agent of the present invention is main material with epoxy resin, and epoxy resin has good process based prediction model, and it all has the adhesive strength of excellence to the surface of metal and nonmetallic materials, so that it is guaranteed that its glue performance, it is ensured that repairing quality；
3, the set shrinkage factor of renovation agent of the present invention is little, and after adding lignin, wood carbon dust and silica flour its shrinkage factor less (minimum can reach less than 1%), and linear expansion coefficient also becomes less, only 6 × 10-5/ DEG C, therefore after renovation agent solidifies, can't there is significant change in its size so that plate face is smooth the most concavo-convex；
4, renovation agent of the present invention has and preferably flows malleability, gently scrapes renovation agent filling after repairing position, and it is whole to flow flattening, and renovation agent itself has good brightness so that repairs position light smooth, does not affect the use after reparation；
5, renovation agent formula of the present invention is simple, composition environmental protection, decreases the use of compound harmful in prior art healant, reduces the infringement to health.
