Abstract
Aiming at the defects in the prior art that the amount of planted glass beads is not easily controlled, the planted beads are not uniform, the process is complex and the like, the invention discloses a bead planting method of glass beads of reflective materials. The method comprises the following steps: a) putting the glass beads into a trough, and raising the temperature of a heating roller to 50-180 DEG C; b) heating a PET (Polyethylene Terephthalate) composite membrane through the heating roller; and c) uniformly scattering the glass beads in the trough through a feeding roller onto the surface of a sticky film layer of the heated PET composite membrane to obtain a PET composite membrane with uniformly-distributed glass beads. The method is simple in process and easy in operation. The temperature of the heating roller is set so that the glass beads can be more firmly stuck on the surface of the sticky film layer of the PET composite membrane. The glass beads on a planted-bead surface are tightly and uniformly arranged, the distribution density of the glass beads in a unit area can be regulated as required, and the use ratio of raw materials is increased.
Description
Technical field
What the present invention relates to reflectorized material plants the pearl method, and what relate in particular to the reflectorized material glass microballoon plants the pearl method.
Background technology
Reflectorized material can be divided into glass microballoon type and microprism two big classes by its different retroreflective principle.What in the production of glass microballoon type reflectorized material the optical property of product is had significant impact is to plant the pearl link, and traditional handicraft adopts the pearl face of planting with base material directly to contact with static glass microballoon, lets base material plant tackifier on the pearl face in the base material operational process; Naturally adhere to the way of glass microballoon; This causes the glass microballoon skewness easily, can't closely arrange the soot layer ply; The serious waste starting material, and influence glistening intensity and product is apparent.
For example; Open day be that application for a patent for invention that on 04 27th, 2005, publication number CN1854773, name are called " production of glass micropearl reflecting-film and single-layer coplanar tree " has disclosed that a kind of employing is pneumatic plants pearl and static is planted the pearl process combined; Select for use heat cured tackifier to make glass microballoon be uniformly distributed in surface of pressure-sensitive adhesive, form the soot layer of single-layer coplanar tree.Though it is evenly tight that the technical scheme of this invention application has had the pearl of planting, strengthen the advantage of intensity of light reflection, still there is following weak point in it:
The one, need preheat glass microballoon when producing and feed hot-air, complex process, restive, and also the distribution of glass microballoon is also inhomogeneous; The 2nd, need apply electric field, let away the roller excessively and the glass microballoon of film distinguish positively charged and negative charge, there is serious potential safety hazard, and is unfavorable in electric field, adding glass microballoon; The 3rd, bubbling air can make glass microballoon floating, makes it be adsorbed onto substrate backside, after pressing, influences the homogeneity of the apparent of product and glass microballoon implantation depth, wastes starting material simultaneously, increases production cost.
Summary of the invention
The present invention is directed to that the glass microballoon that exists in the prior art plants that pearl is measured bad control, plants that pearl is inhomogeneous, above-mentioned defective such as complex process and waste of raw materials, what a kind of new reflectorized material glass microballoon was provided plants the pearl method.
In order to solve technique scheme, the present invention realizes through following technical scheme:
The reflectorized material glass microballoon plant the pearl method, may further comprise the steps:
