As the improvement of technique scheme, described substrate upper and lower surface is equipped with described fireproof plate.
As the improvement of technique scheme, the edge of described fan blade is provided with chamfered edge.
It is substrate that the utility model adopts PVC foamed board, and the fireproof plate that laminating is made by thermosetting resin impregnated paper on substrate, compare with existing fan blade, it has the advantages such as quality is slim and graceful, fire prevention, wear-resisting, high temperature resistant, dustproof, water proofing property is good, weatherability is good, and quality is even, rigidity by force, have an even surface.The fireproof plate of fitting on the substrate of making at PVC foamed board, especially can overcome the defect that PVC foamed board at high temperature can sagging distortion.The utility model is also applicable to outdoor fan and uses.
Accompanying drawing explanation
Fig. 1 is a kind of fan blade embodiment's of the utility model structural representation;
Fig. 2 is a kind of another embodiment's of fan blade of the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated in further detail.
Fig. 1 is the overall structure schematic diagram of a kind of fan blade of the utility model, and the utility model is mainly comprised of 2 parts, substrate 1, top layer 2.Substrate 1 is fitted and connected with top layer 2, and substrate 1 adopts PVC foamed board.So-called PVC foamed board (Polyvinyl chloride foam Board), can be described as again and avenges not plate and An Di plate, and its chemical composition is PVC＝polyvinyl chloride.The fireproof plate that make for fitting in the thermosetting resin impregnated paper of substrate surface on top layer 2.So-called thermosetting resin refers in heating, adds and depress or under curing agent, action of ultraviolet light, carry out chemical reaction, and crosslinking curing becomes a large class synthetic resin of insoluble not fusant matter.This resin is generally solid or the thick liquid that molecular weight is not high before solidifying; In forming process, can soften or flow, thering is plasticity, can be made into definite shape, chemical reaction occurs again and crosslinking curing simultaneously; Sometimes emit some by products, as water etc.This reaction is irreversible, and once solidifying, then pressurized, heated also can not soften once again or mobile; Excess Temperature, decomposes or carbonization, and this is the basic distinction of itself and thermoplastic resin namely.In this case, the thermosetting resin of employing is preferably melamine formaldehyde resin or urea formaldehyde resin or phenolic resin, can certainly be other thermosetting resins, as epoxy resin, unsaturated resin, polyurethane etc.Fireproof plate has another name called refractory slab, formal name used at school is thermosetting resin-impregnated paper high-pressure laminated board, and english abbreviation is HPL(Decorative high-Pressure Laminate), be surface finish refractory building material, there is abundant surface color and polish, lines and special logistics performance.Fireproof plate adopts body paper (titanium valve paper, kraft paper) through the impregnation process of melamine and phenolic resin conventionally, and High Temperature High Pressure is made, and can certainly adopt other thermoset resin materials as above.
The utility model embodiment, is substrate because fan blade adopts PVC foamed board, and quality is slim and graceful, can improve the running usefulness of fan, and rigidity is strong simultaneously, the rigidity requirement to flabellum in the time of can guaranteeing ceiling fan work; PVC foamed board has an even surface, and the natural flaw without natural timber, can reduce product reject ratio; Anti-flammable is good, not combustion-supporting and not spontaneous combustion, and moistureproof and waterproof might as well, can imbibition, thereby can be used for outdoor gardenly ceiling fan; PVC foamed board quality is even, is conducive to counterweight complete; In addition, the fan blade of producing compared to materials such as existing polystyrene series (ABS), PC and PPO, PVC foamed board low price, and the recyclable recycling of base material, thus reduced the use amount of log scale, be beneficial to environmental protection.And the fireproof plate that top layer adopts thermosetting resin impregnated paper to be pressed into through high temperature, height, can overcome well the defect that PVC foamed board at high temperature must sagging distortion, thereby greatly improve fan blade anti-sagging intensity at high temperature, improve application area and the working life of fan blade.And the utility model fits in substrate by the fireproof plate of making, easy to process.
Further, the density of described PVC foamed board is 0.3 ~ 0.8 g/cm
3, the thickness of described PVC foamed board is 2.0 ~ 8.0mm, the thickness of described fireproof plate is 0.4 ~ 2.0mm.Fireproof plate has plain color outer surface or wood grain look outer surface, can certainly take other shades of colour patterns, thereby obtains pleasing outward appearance.
Preferably, fireproof plate outer surface is formed with three-dimensional version line, or plastic relief, as imitative wood grain face, particle-surface etc., thereby produces various outward appearance, further increases the aesthetic feeling of outward appearance.
Further, the upper and lower surface of substrate 1 is equipped with above-mentioned top layer 2, be all fitted with above-mentioned fireproof plate, as shown in Figure 2, thereby can make fan blade not limit the face of installation, even can use a period of time that blade is changed to direction (face) installation, thereby offset timeliness bending deflection, prevent that fan blade afterbody is sagging, extend the working life of blade.
Better, the edge of fan blade is provided with chamfered edge (chamfering), the structure that subtracts material is set in edge, make brim-portion thickness relatively smaller, fan blade inclination several angle is installed simultaneously, thereby reduce the suffered resistance of fan blade rotation process, the rotational efficienty that improves fan reduces energy consumption.Chamfered edge position can be that cross section is the rounding off structure of circular arc, can be also rectilinear chamfering structure.In existing ceiling fan safety standard, decorate under the prerequisite of blade lowest edge thickness limits (3.3mm), with different streamline planes or curved surface, reduce the thickness of decorating blade edge, and then improve windage, the air agitation of ceiling fan operation and reach higher motor running efficiency.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
