Abstract
The invention relates to the reflecting film manufacturing technique field, in particular to a high-strength reflecting film electrostatic bead-planting technique. Through adopting the static planting technique and temperature control, glass beads can be plunged into an adhesive layer on the planting film, and the plunged depth is one third to half of the microsphere diameter. The technique can solve the problem that the glass bead surface electrification in air current bead distribution, can cause the bead-planting surface to overlap with floating beads in the existing bead-planting technique, thereby greatly improving the density of the glass microsphere and enhancing back reflection performance.
Description
Technical field
The present invention relates to the reflective membrane production technical field, especially a kind of high-strength reflecting film bead planting technique that is used for.
Background technology
Reflective membrane can be divided into beaded glass type and microprism two big classes by its different reflex reflection principle.Most important operation is to plant the pearl link in the production of glass microballoon type reflective membrane, the many employings of traditional handicraft will be planted the way that the direct and static glass microballoon of pearl face contacts, cause the glass microballoon skewness easily, can't closely arrange soot layer ply, serious waste starting material, and influence glistening intensity, in addition, generally adopt cold compoundly, the degree of depth that is absorbed in of glass microballoon is not easy to grasp.Planting the pearl operation is most important link during glass microballoon type reflective membrane is produced, and plants the performance of the direct decision of the quality high-strength reflecting film reflex reflection of pearl operation.The high intensity level product bead planting technique of tradition adopts air-flow cloth pearl more, and this technology is applicable to that more the glass microballoon of less order number plants pearl.But easily cause the differentiation of glass microballoon size two-stage in this process implementing process easily, size distribution is inhomogeneous, easily grows dim behind the cloth pearl; Cloth pearl density was not high enough after microballon was subjected to airflow collision, easily produced static between the microballon, and pearl overlaps to form a large amount of floating pearls layer by layer, wastes starting material, and influences the reflex reflection performance of product.
Summary of the invention
The technical problem to be solved in the present invention is: cause the problem of planting the overlapping floating pearl of bead surface at glass microballoon surface charging in the air-flow cloth pearl in the existing bead planting technique, the invention provides a kind of bead planting technique.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bead planting technique that is used for reflective membrane production, adopt the static bead planting technique, and the degree of depth that makes glass microballoon be absorbed in adhesive layer on the beads formed film by temperature control is 1/3～1/2 of a bead diameter.
Concrete operations step of the present invention is:
A. glass microballoon is preheated to 85～90 ℃ in baking oven;
B. the glass microballoon after the preheating is at the uniform velocity added in the high-order pearl groove, again changing over to and plant in the pearl groove at the uniform velocity from high-order pearl groove;
C. adopt electrostatic equipment to make away the film roller positively charged, make that to plant in the pearl groove glass microballoon electronegative:
D. beads formed film is by walking the film roller lotus that becomes positively charged, beads formed film when planting the pearl groove, plant glass microballoon in the pearl groove by the even tight distribution of electric charge suction-operated in the beads formed film surface;
E. beads formed film is by drying tunnel baking-curing under 100 ℃～105 ℃ temperature, and the degree of depth that is absorbed in adhesive layer is 1/3～1/2 of a bead diameter.
The particle diameter of the glass microballoon described in the present invention is 60 microns～90 microns, refractive index Nd=1.93, when refractive index Nd greater than 2.0 the time, the thickness of the focus layer on the reflective membrane must increase accordingly, the integral thickness that increases reflective membrane is unsuitable for use.
Angle and surface level when the beads formed film described in the present invention goes out the pearl groove are at 45, can increase the contact area of beads formed film and glass microballoon, to reach the single face layer purpose of closely arranging altogether.
To plant the distance of pearl groove lowest part be 120mm to the film roller distance walked in the pearl groove of planting described in the present invention.
Beads formed film described in the present invention is the poly-terephthaldehyde's macrogol ester film that is coated with the peelable adhesive layer of 25 microns～45 micron thickness, and the thickness of poly-terephthaldehyde's macrogol ester film is 50 microns.
The invention has the beneficial effects as follows that the density that can improve glass microballoon greatly of the present invention strengthens the reflex reflection performance.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
1. bead inlet ports among the figure, 2. high-order pearl groove is 3. planted the pearl groove, 4. goes out the hole of bead.
Embodiment
Example one:
Selecting particle diameter for use is 60 microns～90 microns, the glass microballoon of refractive index Nd=1.93, qualified glass microballoon is gone Electrostatic Treatment, put into baking oven again glass microballoon is preheated to 85～90 ℃, after put into high-order pearl groove, glass microballoon at the uniform velocity adds, drop into by high-order pearl groove again and plant in the pearl groove, glass microballoon in planting the pearl groove by negative charge on the electrostatic equipment band.
Poly-terephthaldehyde's macrogol ester (BOPET) film of selecting 50 micron thickness for use is as planting the pearl basement membrane, the peelable adhesive layer of coating 25 micron thickness forms beads formed film on the BOPET film, after drying tunnel oven dry, have static in walking on the film roller of drying tunnel, the beads formed film lotus that becomes positively charged when walking the film roller.Beads formed film is when planting the pearl groove, because the charges of different polarity attract each other, glass microballoon is distributed to the surface of beads formed film, and angle and the surface level of beads formed film when going out to plant the pearl groove is at 45, increases adsorption area, realizes that single face layer closely arranges altogether.
Beads formed film behind the cloth pearl enters drying tunnel baking-curing under 100～105 ℃ temperature after by ball-planting device, and the degree of depth that makes glass microballoon be absorbed in adhesive layer is 1/3～1/2 of a glass microballoon diameter.
