Abstract
The invention discloses a rigid polyvinyl-chloride signboard and a manufacturing method thereof. The rigid polyvinyl-chloride signboard comprises a main signboard body, an upper end cover and a lower end cover, wherein the main signboard body is molded through the extrusion of rigid polyethylene, and the upper end cover and the lower end cover are fixed at the upper end and the lower end of the main signboard body and are molded through the injection of the rigid polyethylene. The rigid polyvinyl-chloride signboard produced by adopting a mode that the main signboard body and the end covers at both ends are mutually fixed has the advantages that materials are environment-friendly and easy to obtain, the structure is simple, the manufacturing cost is low, and the rigid polyvinyl-chloride signboard is easy for large-scale production.
Description
Technical field
The invention belongs to municipal corporation and enterprises and institutions' signboard is used the device field, especially relate to a kind of rigid polyvinyl chloride signboard and preparation method thereof.
Background technology
Employed in the market signboard and billboard mostly adopt plank or metal to process.Wooden signboard is processed by the monoblock plank, and the forest reserves are had threat, in whole world energy-saving and emission-reduction nowadays; Under the overall background of protection environment, extremely urgent with the replacement of novel environment friendly material, and wooden signboard complex manufacturing technology; Need select for use the high-quality log to separate plate earlier, polish, split the technology of a series of complicacies such as drying behind putty, polishing, the surface lacquer for a long time, require the workman highly specialized, time-consuming, take a lot of work, require great effort; Integrated cost is high, and wooden signboard is not ageing-resistant, not humidity; Yielding, in the outdoor short time, will occur falling lacquer, slight crack, putty come off, turn to be yellow, etc. phenomenon, and be difficult to renovation.Metal signboard cost of manufacture is high, is generally 3-4 times of traditional signboard cost, and complex manufacturing technology is highly specialized, needs specialized tools to cut out plate, flap, and the surface needs not corrode with ability japanning after the chemical agent corrosion, and paint is difficult to adhere to.And the metal signboard has collision large tracts of land depression will occur because material is thinner slightly, can't repair and since the surface need after the chemical agent corrosion, just can spray paint; So once use; Can't renovate utilization again, in case outmoded, damage or content alteration will become waste product, quite waste.
Summary of the invention
In order to solve and to overcome conventional wooden signboard and metal signboard many deficiencies and the defective on making, environmental protection, fire-fighting, durable and cost, the present invention proposes a kind of rigid polyvinyl chloride signboard and preparation method thereof.
A kind of rigid polyvinyl chloride signboard, its technical scheme do, comprises the signboard main body of hard polyethylene extrusion modling, is fixed on the signboard main body upper and lower end cap at two ends up and down.The rigid polyvinyl chloride signboard that the mode that adopts signboard main body, two ends end cap to interfix is produced, material environment friendly be prone to get, simple in structure, cheap, be easy to large-scale production.
The signboard main body is the hollow structure of the band keel of an extrusion molding.The signboard main body is a hollow structure in this step, reduces materials, alleviates signboard weight, and the hollow structure of the band keel of an extrusion molding strengthens the signboard physical strength.
Upper and lower end cap and signboard main body link position are provided with shutoff, and end cap was fixed through shutoff reinforcement and being connected of signboard main body in this step, increase the signboard life-span.
Frame is nested with the metal edge frame of a protection signboard and a beauty function around the said signboard.Metal edge frame is nested up with signboard, has both protected signboard, has increased the decorative effect of signboard again.
Said signboard surface has been coated with the coat of metal of metal finishing effect.
The said signboard back side is fixed with the securing stationary installation of signboard.This structure makes more easy fixation of signboard, and is more convenient when signboard uses.
The invention still further relates to the method for making above-mentioned rigid polyvinyl chloride signboard; With pvc tubing grade resins is that major ingredient (being commonly called as pvc-5,7,8 type resins) is aided with lead sulfate tribasic, dibasic lead phosphite, calcium stearate, stearic acid, paraffin, precipitated calcium carbonate, titanium white powder, Tissuemat E, mixes by weight proportion; High-temperature fusion is extruded formation signboard main body and injection moulding forms upper and lower end cap, and the corresponding respectively signboard main body of upper and lower end cap is secured together at two ends up and down.The concrete prescription as follows:
PVC 70-100 part
Lead sulfate tribasic 2-3 part
Dibasic lead phosphite 0.5-1 part
Calcium stearate 0.2-0.5 part
Stearic acid 0.3-0.6 part
Paraffin 0.6-1 part
Precipitated calcium carbonate 10-50 part
Titanium white powder 2-3 part
Tissuemat E 0.1-0.15 part.
In said titanium white powder, lead sulfate tribasic, dibasic lead phosphite, the calcium stearate one or more are stabilizing agent.
Said stearic acid is a plastifier.
Also added filler in the said rigid PVC, sneaking into filler is precipitated calcium carbonate, thereby has increased the intensity of whole signboard.
