Description
Technical field
The present invention relates to a kind of composite wooden template and production technologies, more particularly to a kind of includes plank, glass-fiber-fabric and solidification
The glass steel composite wooden template and production technology of resin.
Background technique
Traditional architecture template is mostly one kind of glued board, is had following defects that
1, rounding needs to cut down a large amount of forest, and very big destruction is caused to ecological environment；
2, veneer drying arrangement needs to put into that higher cost builds baking room and operating cost is higher；
3, for veneer gluing assembly using vertical and horizontal staggered assemble pattern, the probability of blanket dislocation overlapping is high heavy, piece compared with
Greatly, unbalance stress, intensity is not high, and cost is high, is extremely easy delamination；
4, template surface is easily bonded concrete, and clear water effect is not achieved in concrete surface out-of-flatness, and the number of turnover is not high,
Effect is had enough to meet the need in multiple turnover mould edges of boards angle delamination out-of-flatness, influence again.
To solve the above-mentioned problems, the applicant has been proposed wood skin and is superimposed glued composite shuttering with core plate, this
Template can be processed using waste and old wood, can save a large amount of timber, but be had following defects that longitudinal with the superposition of multilayer wood skin
Glued hot-forming, the wooden water suction of surrounding edges of boards leads to delamination after being easy expansion；Wood skin crosses glue using interlayer and is easy in technique
Existing glue locally leaks white and leads to profiled sheeting wood skin delamination, and raw material use a small amount of second level skin or hole plate in wood skin selection, repair
Benefit can not be perfect, the easy delamination of overlapping；Its surface using glue surface be heat-treated or cover modeling, thus make template surface with mixed mud knot
It is not bonded when conjunction, easy mold release.
In order to overcome the above problem, the applicant has also been proposed vertical carbon fiber template, including the compound musculus cutaneus of carbon fiber and
Core plate, the compound musculus cutaneus of carbon fiber are made jointly of carbon cloth, spunlace non-woven cloth, atactic copolymerized polypropene and binder,
The core plate is formed by curing by the splicing of multiple battens, and two pieces of compound musculus cutaneus of carbon fiber are flat greatly with the two sides of the core plate respectively
Paste connection in face.But this template still has that quality is affected by binder and processes complexity.
In addition, all there are the following problems for above-mentioned all templates: easy delamination, water flowing expansion, became uneven, rough surface, at
The concrete surface of type is coarse, and needing to touch ash keeps its smooth, and the number of Reusability is few, and generally 6-8 times.
Summary of the invention
The object of the invention is that providing one kind to solve the above-mentioned problems is not easy that delamination, surface is smooth, thickness is equal
Even, high temperature resistant, the glass steel composite wooden template of waterproof acid and alkali-resistance and production technology.
