High light color reflective cloth and preparation technology
Technical field
The present invention relates to a kind of high light color reflective cloth preparation technology, belong to reflective cloth and make the field.
Background technology
Publication number CN1760444A, title " a kind of manufacture method of silvery reflection cloths ", the preparation method's of this silvery reflection cloths step is as follows: a, on poly-cruel film gluing, dry back is compound with polyethylene film; B, will spill glass microballoon after the above-mentioned composite membrane preheating, and then heating, make the thermoplastic polyethylene cling glass microballoon; C, with aluminium-vapour deposition on above-mentioned glass microballoon; D, on above-mentioned aluminum plating glass microballon film gluing, dry back is compound with fabric; E, the aluminizer on the above-mentioned fabrics layer is peeled off.The fact of objective reality is: the one, and fabric face need pass through specially treated; The 2nd, plant pearl gluing thickness requirement height----gluing and approach, have influence on the viscosity fastness of polyester film and glass microballoon, gluing is thick, and then pearl easily buries in the glue, influences glistening intensity, and the face sense is grown dim; The 3rd, can only make the face sense and be the reflective cloth of silver gray high brightness, brightness is at 300-500cd/1x. * m
2(5 ° of viewing angles 12 of incidence angle ') can't be made the face sense and be colored highlighted reflective cloth; If when color was colored, brightness had very low, brightness is at 100-200cd/1x. * m
2In (5 ° of viewing angles 12 of incidence angle ').
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of sense and both be colored, have the high light color reflective cloth and the preparation technology of high brightness again.
Design: 1, design principle: retroreflecting is a kind of optical phenomena.Shine when light on the object of lens and so on and after reflecting, focus on, have through the lens refraction from the focus reflection again and return light source direction, Here it is retroreflecting, and reflective cloth utilizes the principle of retroreflecting will shine incident light on it through after the effect of glass microballoon just, can reflect by the primary source direction, thereby improve the visibility of self.2, in order to achieve the above object----makes reflective cloth surface can reflect the bright color of high brightness, just must aluminize, but this aluminizing, not directly aluminizing to glass microballoon, but before aluminizing, after being coated with one deck coloured glue on the glass microballoon film, aluminize again, thereafter, in order not influence the brightness of product, before aluminizing, be coated with the transparent coloured glue of a floor height, make light can penetrate color layer fully and arrive aluminium coated.To satisfy simultaneously directly and after being coated with coloured glue on the beads formed film, can all be shifted this characteristic, make beads formed film, under heating state, hot melt be arranged at normal temperatures for nonpolar.
Technical scheme 1: high light color reflective cloth, it comprises the composite membrane that is made of polyester film and glue-line, is equipped with glass microballoon on the composite membrane, is coated with a floor height transparent color glue-line on the glass microballoon film, is coated with aluminium lamination on the colored glue-line, scribbles composite layer on the aluminium lamination.
Technical scheme 2: high light color reflective cloth preparation technology, gluing on polyester film, the oven dry back is compounded to form composite membrane with polyethylene film, above-mentioned composite membrane heating back is planted the upper glass microballon and made polyethylene cling glass microballoon on its surface, after being coated with the transparent coloured glue of a floor height, oven dry on the glass microballoon film, again with aluminium-vapour deposition on the glass microballoon that scribbles coloured glue, and with gluing once more on the glass microballoon film after above-mentioned the aluminizing, the oven dry back is compound with fabric, at last the aluminizer on the above-mentioned fabrics layer is peeled off, high light color reflective cloth.
The present invention compares with background technology, and the one, adopting the prepared reflective cloth color of the application is color reflective cloth, brightness height not only, color is very bright-coloured, and the surface of cloth is very fine and smooth; The 2nd, glistening intensity can reach 400cd/1x. * m
2More than (5 ° of viewing angles 12 of incidence angle '), surpassed the EN471ClassII standard; The 3rd, fabric face need not specially treated, as long as general the processing; The 4th, certain because of the thickness of polyethylene film, it is certain to plant the pearl condition, and it is nonpolar that the surface is, and has avoided causing influence to product, stable and reliable product quality because of the gluing thickness; The 5th, coloured glue wet concentration high transparent makes light well to see through coloured glue and arrives aluminium coated, has solved the low problem of brightness.
