Abstract
The invention relates to a production method for a preformed reflective marking tape. In the invention, the conventional rolling type production method is changed into an extrusion type production method. The method comprises the following steps of: weighing a certain amount of organic material, placing the organic material into a mixer to mix the organic material uniformly, and then feeding the organic material to a general plastic extruder to extrude a film base; painting a layer of a high-strength adhesive on the film base; uniformly implanting glass microballoons on the adhesive; and finally performing slitting and packing to obtain a product. The abrasive resistance, flexibility, weatherability and the like of the product are improved greatly; the adhesive force between the superficial high refractive glass microballons and a base material can be improved; and the abrasive resistance of the reflective marking tape can be strengthened.
Description
(1) technical field: the present invention relates to performing reflective marker belt, belong to the roadmarking technical field.
(2) background technology: performing reflective marker belt is usually used in making the sign of traffic marking, sign and the underground pipeline on road surface, often be found in places such as various standard highways, urban road, harbour, airport, charge station, airport, sports ground, parking lot, factories and miness, tunnel, because of it is difficult for disperseing driver's notice, and be difficult for being blocked, also be not subjected to the restriction of infield and just used by increasing occasion by shade tree or buildings.But existing performing reflective marker belt all is that what to adopt is calendering formula technology, and efficient is low, and the quality instability can not satisfy society need.
(3) summary of the invention:
1, goal of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of new production method is provided, make the product efficiency height of producing, better quality is to satisfy needs of society.
2, technical scheme technical scheme of the present invention is: a kind of production method of performing reflective marker belt, it is that traditional calendering formula production method is changed into extrusion type production method, and concrete grammar is: send into general-purpose plastics extruder extruding slice base after having taken by weighing organic material according to quantity and having placed batch mixer to mix; Brushing one deck high-strength structureal adhesives on the sheet base again; Then on bonding agent, plant glass microballoon equably; Cut at last, pack product.
The used extruder of the inventive method is general plastic extruder; The raw material that is used to push base in blocks is identical with rolling process commonly used with consumption; The beaded glass that is implanted on the bonding agent is generally 30～40 orders; Extrusion temperature is 140-160 degree centigrade.According to the difference of purposes, when after extruding, carrying out press polish, can select plane or relief pattern press polish machinery.The width of marker tape cuts with the slitter sanction after pearl is planted on the surface as required.Can determine all size of 3cm～100cm.This marker tape can arbitrarily be made traffic marking, various figure, literal, arrow, simulation solid figure and traffic above-ground sign etc.; The size of graticule, sign can be cut out according to client's needs and be cut; The color of marker tape can be made into various looks, its main look be white, yellow, redness, blueness, black, orange, green seven kinds.
3, beneficial effect: the present invention is owing to change original calendering process into pressing method, and the raw material that mixes is by extrusion equipment, and extruder for shaping is passed through in fusion at high temperature.Reactions such as a series of crosslinked, modifications take place in material in extrusion process, material is formed have flexible micropore shape structure, and the wearing quality of product, pliability, weatherability etc. all have great raising; Owing to having additional cementation layer reflecting glass Bead closely is bonded together with base material.The cementation layer decapacitation improves outside the bounding force of surperficial high refracting glass pearl and base material, has also strengthened the abrasive resistance of reflective marker belt simultaneously.Good through reflecting effect on probation, visual range can reach 300 meters far away.Can reach goal of the invention fully.
(4) embodiment: preferred implementation of the present invention is: the concrete preparation method of this product comprises four procedures: compounding process, extrude operation (conveying, preheating, incipient melting, fusion, extrude, press polish, rolling), painting process (gluing, secondary are planted pearl, oven dry, cooling) and cut packaging process.Concrete preparation process is as follows:
A, compounding process: taken by weighing each component raw material on request, poured in the batch mixer and mix;
B, extrude operation: extruding the topmost equipment of operation is machine barrel and die head.Machine barrel is divided into 6 zones, and die head divides seven zones.First and second district's temperature of machine barrel is set in 80～120 ℃, and the 3rd to the 6th district's temperature is set in 130～160 ℃, and the flange temperature is set in 130～160 ℃, and die head is respectively distinguished temperature and is set in 140～180 ℃.Earlier machine barrel, flange and die head are warmed up to design temperature during production, begin to add the raw material that mixes then.Pour starting material into charging spout when reinforced, be transported in the hopper, enter machine barrel by hopper again by worm conveyor.Raw material at first enters the preheating zone after entering machine barrel, carries out preheating in the preheating zone, mixes again.Along with screw rod rotation, raw material is pushed ahead, and enters fritting zone, melting zone, flat-temperature zone, enters die head by flange at last, the starting material of melt-front is extruded cooling forming in air under the high pressure logistics that the rotation of screw rod produces.When extruding, adjust the degree of tightness of temperature, die lip fastening bolt, the degree of tightness of reinforced press strip etc. according to the performance at die head place, the sheet base of extruding is met the demands.The product of extruding is through press polish, and last rolling is stored.Finish and extrude.
C, painting process: elder generation's brushing one deck high-strength structureal adhesives (chlorine dibutyl glue kinds tackifier on the extrudate piece base, SBS class tackifier etc.), plant 30～40 purpose beaded glasses more in the above equably, by drying tunnel oven drying, rolling after cooling, be put on the storage horse, finish coating.
D, cut, packaging process: according to customer requirement, adjust the distance between the slitter blade, the sheet base is taken off and is placed on the unwinding rack from the storage horse, begin to cut, cut the back rolling of curling, joint sealing is finished product.
The marker tape that the present invention produced is shaped as sheet band shape, and thickness is at 1.2～2.5mm, and bandwidth is at 800～1200mm.Can cut out arbitrarily by customer requirements and cut.Can arbitrarily make means of transportation products such as traffic marking, arrow, pattern, literal, simulation dimensional mark and surface mark.Various signal colourations such as that the color of marker tape can be made is red, white, yellow, black, indigo plant.
Claims (3)
