Abstract
A bamboo-substrate thermosetting plastic concrete formwork belongs to the field of artificial boards and is a plate formed by veneering a bamboo plywood substrate and a thermosetting plastic plate and has a symmetrical laminating structure. The bamboo plywood substrate is formed by veneering an impregnated long-short bamboo screen which is used as a core, an impregnated bamboo screen which is used as an inner layer and a single-side glued cross-grain wood plate which is used as a surface via thermal pressing, and the thickness of the substrate is about 90% of the total thickness after operations of cutting edges and equal-thickness double-side polishing. The thermosetting plastic plate is a sheet which is pressed by thermosetting resin impregnated paper, the thickness of the sheet ranges from 0.4mm to 1.2mm, and the back surface of the thermosetting plastic plate is rough while the front surface can be a smooth plane or a concave-convex surface with certain patterns. The bamboo plywood substrate and the thermosetting plastic plate are veneered via thermal pressing. Edges of the plates are sealed by coating. The bamboo-substrate thermosetting plastic concrete formwork is a novel formwork which combines advantages of high mechanical strength of a bamboo plywood formwork and fine physiochemical performance of a thermosetting plastic formwork.
Description
Technical field the utility model belongs to the wood-based plate field.
Background technology is present, and build concrete template (being called for short template, down together) has 4 classes both at home and abroad.The first kind is the steel form with steel processing; Second class is the wood plywood template with Wood Processing; The 3rd class is the bamboo plywood form with bamboo processing; The 4th class is the plastic formwork with hot-melt plastic processing.The steel raw material of steel form and the wood raw material of wood plywood template all are China's resources in short supply, and need a large amount of imports every year, thereby its development is restricted.Because timber resource shortage, native land man has proposed the industry policy of " with the bamboo lumbering ", " to mould Dai Mu ", and under the guiding of this policy, recent two decades successively develops bamboo plywood form and hot-melt plastic template, and development speed is very fast.Bamboo plywood form has intensity height, density is little, price is low advantage, but easily imbibition in use, dehydration shrink, and the internal stress that is produced will cause bonding strength to reduce, so the repeated use number of times is its shortcoming less.Though hot-melt plastic template intensity is low, density is big and unit price is high, can not produce imbibition, dehydration contraction, reusing is its advantage often.But at home and abroad there is no the report of thermosetting plastics template at present.
The summary of the invention the purpose of this utility model is to be base material with the bamboo plywood, and the sheet plastic of suppressing with the thermosetting resin impregnated paper at 2 plate faces of base material (being called for short the thermosetting plastics plate, down together) glues together well-thought-out plan based thermoset plastic formwork with it.Its 4 edges of boards carry out edge sealing with coating to be handled, and in the hope of reaching the advantage that makes full use of the high and thermosetting plastics plate good physical and chemical properties of bamboo plywood form mechanical strength, thereby becomes a kind of high performance new type formwork.
The technical solution of the utility model is as follows: the base material of bamboo based thermoset plastic formwork is that the long and short bamboo curtain splint by impregnation is a sandwich layer, the impregnation bamboo mat is an internal layer, the band veneer of single spreading is the top layer, forms the slab with symmetry layer structure, becomes base material through hot-press gluing.Base material needs by cutting edge and the two-sided sanding processing of uniform thickness.The thickness of base material accounts for about 90% of bamboo based thermoset plastic formwork thickness.2 panels at base material glue together 1 thermosetting plastics plate respectively.The thermosetting plastics plate is suppressed with the thermosetting resin impregnated paper, and thickness is the thin plate of 0.4～1.2mm, and the sand hair is wanted at its back side, and the front can be smooth plane, also can be the male and fomale(M﹠F) with certain floral designs.Behind the backsizing assembly of bamboo plywood substrate surface or 2 thermosetting plastics plates, form sheet material (Fig. 1) by hot-press gluing with symmetry layer structure.4 edges of boards of bamboo based thermoset plastic formwork carry out edge sealing with coating, form the bead layer of waterproof.
Description of drawings
Accompanying drawing 1 is the schematic diagram of bamboo based thermoset plastic formwork symmetry layer structure,
Among the figure: the 1st, the thermosetting plastics plate, its front is outwardly;
The 2nd, the band veneer top layer (coated face is inwardly) of bamboo plywood base material;
The 3rd, the impregnation bamboo mat internal layer of bamboo plywood base material;
The 4th, the sandwich layer that the bamboo plywood base material is made up of the long and short bamboo curtain splint of impregnation;
The 5th, the symmetrical centre plane of bamboo based thermoset plastic formwork;
The specific embodiment
1. the preparation of bamboo plywood base material
Long and short bamboo curtain splint and bamboo mat be impregnated phenolic resin glue and reduce moisture content, band veneer single face brushing phenolic resin glue through super-dry all; Be that sandwich layer, 2 bamboo mats are that internal layer, 2 band veneers are that the slab with symmetry layer structure is formed on top layer (coated face inwardly) with several long and short bamboo curtain splints then, become base material through hot-press gluing.After base material passes through cutting edge in length and breadth again, carry out the two-sided sanding processing of uniform thickness.
2. the preparation of thermosetting plastics plate and requirement
The thermosetting plastics plate is suppressed with the thermosetting resin impregnated paper, and thickness is the thin plate of 0.4～1.2mm, and the processing of sand hair will be carried out in its back side, and the front can be smooth plane, also can be the male and fomale(M﹠F) with certain floral designs.
3. the gummed of bamboo plywood base material and thermosetting plastics plate
Earlier to the phenolic resin glue of the back side brushing Thermocurable of 2 surfaces of bamboo plywood base material or 2 thermosetting plastics plates, place each 1 of thermosetting plastics plate respectively at bamboo plywood base material upper and lower plates face again, and the back side that makes the thermosetting plastics plate inwardly, the front is combined into symmetry layer structure slab outwardly.Under 130～150 ℃ of conditions, use 15～30kgf/cm then
2Pressure, hot-press gluing well-thought-out plan based thermoset plastic formwork.
4. cutting edge
By edging and trimming saw bamboo base heat-curing plastic template is carried out cutting edge once more, make it to reach the book size of regulation.
5. edge sealing
First 4 edges of boards to bamboo based thermoset plastic plate are coated with Puttying limit portion hole are filled and led up, and it is smooth to wait to do the back sand milling, and then brushing paint forms the waterproof edge sealing layer 2～3 times.
By the bamboo based thermoset plastic formwork of above-mentioned embodiment formation symmetry layer structure, it has the advantage of bamboo plywood mechanical strength height and thermosetting plastics plate good physical and chemical properties.
