Abstract

The invention relates to a bead-planting substrate used in luminescence cloth processing by a transfer method, and especially relates to a reflecting material bead-planting substrate, and belongs to the technical field of reflecting materials. The reflecting material bead-planting substrate comprises a bead-embedding PE film layer, a glue layer, and a PET film layer. The bead-embedding PE film layer is formed by three layers of an outer layer, a middle layer, and an inner layer. The surface of the outer layer is bonded with the PET film layer through the glue layer. The inner layer where the bead-planting substrate and glass beads contact is stick resistant, and the inner layer is easy to peel off. The outer layer is high temperature resistant and cannot easily deform.

[0041] Examples:

[0042] A kind of reflective material planting bead substrate, the structure is like figure 1 As shown, the reflective material bead planting substrate includes a beaded PE film layer 1, a glue layer 2 and a PET film layer 3. The beaded PE film layer is composed of an outer layer 1-3, a middle layer 1-2 and an inner layer 1-1 three-layer composite, the surface of the outer layer is bonded with the PET film layer through the glue layer. The raw material ratio of the outer layer, middle layer and inner layer is shown in Table 1, Table 2 and Table 3.

[0043] The present invention finally adopts a blow molding method to produce the bead-embedded PE layer of the reflective material planting bead substrate, and then composite processing with the high-temperature resistant PET film to make a finished bead planting substrate such as Figure 4.

[0044] A crystal-free film blowing machine with a screw diameter of 65mm and an orifice diameter of 450 is used on the equipment. The screw speed is 80 rpm, the barrel temperature is 100°C/125°C/145°C/145°C/140°C, the film head temperature is 140°C/145°C/145°C/148°C, the inflation ratio is 2, and the corona is 42 dyne.

[0047]

[0048] Since the outer layer is not used for plants and only compounded, price additives can be omitted from the perspective of cost saving, which has little effect on the overall plant processing. The outer comparative example is used to reflect the ratio of different costs, the middle comparative example is used to reflect the ratio of different softening points, and the inner comparative example is used to reflect the ratio of different softening points and peeling forces.

[0054] The easy peeling aid is made by mixing the following components in mass fraction: 2% white oil, 5% erucamide, 10% silica, and the rest is carrier LDPE (Dow DFD-4960).

[0055] Table 4 shows the properties of the reflective material beading substrate produced according to Examples 1-5.

[0056] Table 4

[0057]

[0058] If ordinary PE material is used as the base material for planting beads, the softening point of this type of planting bead substrate is generally 100-110°C, the melting point is 125-130°C, and the peeling force> 2N. In the present invention, the ratio of 1C7A to KS560T has a greater influence on the softening point. The softening point under this ratio is just enough to make the glass beads with a diameter of 40-90μm settle by 40-50%. The settlement is too deep and not easy to peel off, and the settlement is too shallow. Drop beads.
