Description

Adhesive stick type long-effect light-reflection material for sign on road surface

The present invention relates to a kind of marking material that is used for the traffic administration on road surface.More particularly this marking material can directly stick on the road, and can be at noctilucence road surface long-acting reflecting table tape.

Existing traffic administration pavement markers, as describing in United States Patent (USP) 92101175X and 92103945X two manuals, the former mainly is the adhesion strength that combines back raising traffic sign object self and road surface with polyorganosiloxane adhesive with pavement markers; The latter then mainly is a kind of ironed panel material of integral layer of road sign that can be reflective.Its surface has one deck polypropylene and can protect road sign pattern on the thin plate to avoid exposing to the weather and be compromised, thereby loses the effect of road sign sign.And the compound reflection traffic marking of narration in the Chinese patent 901088560 just adopts the plastics strip to make base, and glass microballoon is dissolved in the traffic tape of its surface as surface layer.Its defective is to have ignored the prerequisite tension of traffic tape self, anti-folding, and the reality of high tenacity and high-wearing feature needs.Disclosed in another Chinese utility model patent 902239880 then is a kind of geometrical layers body first class face colored belt of making raw material with pottery, the road surface that need dig up highway when this colored belt is constructed, after putting into ceramic grain of rice shape particle layer road surface signal belt then, use the road roller extrusion molding again, and the kraft adhesion coating of belt surface can't peel off at that time, wait for could slowly being demonstrated the colored belt that is covered by kraft after the continuous wearing and tearing of the vehicles.Its shortcoming is the construction trouble, and at following period of time colored belt cisco unity malfunction.

The present invention just can eliminate many deficiencies of above existing traffic sign thing.A kind of the wear-resisting, withstand voltage, corrosion-resistant of high strength degree that have is provided, and it is good to paste performance, and when changing colored belt, peels off easily and do not pollute the road surface, does not damage the road surface, the rational long-acting pavement reflecting marking material of reflective visibility.The present invention be on the basis of former patent of invention 921149662 by after the continuous practice, a kind of various indexs that former base material and batching and manufacture craft have all been done to obtain after the further improvement all are superior to the novel pavement marking material of original application stuck long-service marking line belt.

Inventive result of the present invention is by the modified PVC base material with former employing, has changed the TPR material into, and this TPR material be with carry out mixing a period of time through other batchings of high-speed mixing after, again through calendering, gluing, plant and obtain after pearl, the oven dry.For the high-intensity abrasion resistance that improves the colored belt sheet material, anti-aging and withstand voltage stability, the present invention has also added polypropylene in the TPR raw material, again at 160 ℃--in 300 ℃ the mill behind the heating plasticizing one time, add fill material that proportioning mixes again and carry out that calendering forms after mixing a period of time.

In accompanying drawing one, first procedure is batching required for the present invention: quartz sand, quartz powder, soft calcium powder, lithopone, titanium dioxide, antioxidant, glass microballoon, KH---550, and pigment, join temperature at 80 ℃--mix in-180 ℃ the high-speed mixer.Meanwhile, the temperature of mill is risen to 160 ℃---300 ℃, add polypropylene, TPR base material raw material again after roll spacing on the machine being transferred to the suitable distance of 1.0MM--5MM, in the mill that mixes up roll spacing, plastify.Might make the fused property of polypropylene and TPR like this after the plasticizing.The fill material that high temperature is mixed joins in the mill that is surrounded by the good polypropylene TPR of plasticizing again, and after start was carried out mixing about 10---30 minute, discharging entered the multi-rolling mill calendering.Note, before the mixed packing material is sent into mill, the roll spacing between two rollers in the mill must be transferred to 2MM--6MM, in order to guarantee the equal thickness after the mixing glue laminated of sheet material one time.As a same reason, with the mixed material in the mill, send into multi-rolling mill before, should mix up the distance between several rollers in the calender earlier.Roller spacing between each roller should be transferred between 1MM--5MM.Generally speaking, (1), (2), the temperature of (30) roller should be transferred to 138 ℃ after the start--between 250 ℃, the temperature of (4) (or last) roller should transfer to 90 ℃--is between 100 ℃.And should adopt the low speed reinforced rolling process of advancing during the calendering, roll.When raw material through (4) after (or last) roller calendering, along with the process of lowering the temperature while rolling slowly, can guarantee the sheet material that rolls out at the gluing that and then carries out, plant and can keep making the chlorinated rubber adhesive that newly is coated on the sheet material in the pearl operation, the bond properties that can not go down owing to the high temperature of sheet material, the high temperature of sheet material and make and plant the glass microballoon dissolving deformation that is placed on the sheet material thus.

Accompanying drawing two is stereograms of colored belt product of the present invention.Accompanying drawing three is finished product packing space patterns of the present invention.For the feasibility that manufactures a finished product of marking material of the present invention further is described.We further describe with embodiment.Pour in two rollers or the multiple roll mill load weighted polypropylene GRANULES is some, but should at first mix up the spacing of each roller before this between 1MM-5MM, be load weighted TPR that the particle of thermoplasticity butadiene-styrene rubber is poured between two rollers then, making it to add the quartz sand, quartz powder, light calcium powder, lithopone, titanium dioxide, antioxidant (1) glass microballoon (2) KH-550 (being bought by chemical plant, Gaizhou City, Liaoning), pigment and the good fill material of proportioning that mix through high temperature after about 38 minutes again in the back plasticizing of plasticating under the machine temperature of 160 ℃-300 ℃ of temperature carries out mixing.In mixing process, should be specifically noted that and avoid between roller and roller, producing a lot of gum deposit amounts.In order to guarantee the quality of sheet material, general mixing time should be grasped at 10-30 minute and be advisable.In sheet material mixing, also should in time use simultaneously

The sizing material at tapping knife correction roller two ends is rendered in the middle of the roller.In reinforced process, also should in time sweep in the adding machine from the various materials that fall down between roller, to guarantee the proportion speed degree of sheet material.With the sizing material that mixes, deliver to roll into the sheet material that thickness is 1MM--5MM in the four-roll calender after, send traction chamber traction to.And then just coat and plant pearl glue in the surface at sheet, sprinkling glass microballoon again, the HT--906 pressure sensitive adhesive is then coated at the sheet material back side again in the oven dry back, drying, encloses one deck barrier paper again, puts in storage through air-cooled, cut-parts, rolling, finished product then.
