Stir: the above-mentioned material for preparing is dropped in the horizontal mixer separately stir.Mixing speed is 50 rev/mins and stirs.Mixing time is 10 minutes.Stirring is uniformly dispersed material.Require the change in concentration of each material in matrix to be no more than 4%, special is no more than 3%, and special again is no more than 1%.In whipping process,,,, the stall machine, treat that material cooling continued stirs if temperature surpasses 60 ℃ so in whipping process, note variation of temperature because friction can make material temperature rise.
Multi-layer co-extruded: be positioned over mix in the flat mixer after, drop into two to two groups of materials respectively in the same way in the feeding mouth of engagement type double screw extruder, because the gap is less between the screw rod of extruder; And the formation screw shaped travels forward; In the conjugation district bigger relative velocity is arranged, so material has obtained good mixing and plasticizing, the temperature of extruder charge door is >=100 ℃; The stage casing temperature is 130 ℃-190 ℃, 120 ℃-150 ℃ of discharging opening temperature.Material is through heating and the shearing of screw rod, mixing one-tenth molten condition; Filter through net-changing device then,, get into distributor and distribute again through the measuring pump voltage stabilizing; The material that wherein with the polyvinyl chloride is matrix is in the intermediate layer; The material that with the polyvinyl butyral resin is matrix is in both sides, and to die head, die head becomes three-layer co-extruded composite membrane sheet to the material stretching and extrudes the material of last two extruders through the distributor bout.Wherein the thickness of polyvinyl chloride layer is 0.304mm, and monolayer polyethylene butyral layer is 0.228mm.The thickness of whole composite bed is 0.76mm.Owing to there is the layering of multithread road composite membrane head to isolate, prevent that each layer storeroom from scurrying mutually.Mobile for material can be distributed at die head uniformly, before getting into die head, must get into distributor, make material can on whole die head, obtain effectively distributing uniformly.
Curtain coating: adjust the film that comes out behind the thickness from the extruder die head and press decorative pattern through pressure roller, the surface temperature of roller is 15 ℃-30 ℃.The rotating speed of roller is 4m/min.
Cooling: with the cold wind cooling, temperature is 17 ℃.
Batch: control hauling speed well, reduce the internal stress of film.Speed is 4m/min.
The coextruded multilayer composite distributor that relates in the method is as shown in Figure 1, is by die body 1, and subsidiary engine zonal flow rate adjustment structure 2, subsidiary engine shunting plug 3 are formed.Die body is provided with three charging runners, and one is the main frame charging, and two other is the subsidiary engine charging.Distributor mainly is the distribution of accomplishing melt flow stream through the ratio of control subsidiary engine material PVC in goods PVB and the uniformity and evenly distribute, and can adjust each parameter through adjusting subsidiary engine zonal flow rate adjustment structure.Control well after material ratio and the distributed uniform, material gets into die head (as shown in Figure 3) by distributor, in die head, after being stretched, extrudes material, owing on the die head multithread road is arranged, thus make different material can not mix mutually.Discharging after the die head place controls thickness well.
Also relate to die head in the present invention and go out the decorative pattern technology.The sketch map of die head nature Cheng Wen is as shown in Figure 2.Because PVB belongs to thermoplastic; Along with its mobile performance of rising of temperature can improve; When temperature rises to certain limit and makes PVB reach in the viscoplasticity scope, under the effect of the mould mouth place of die head steel, can form irregular decorative pattern, when leaving the mould mouth, cool off with chill roll; Make decorative pattern 5 to settle out, reached the purpose of Cheng Wen.For the temperature that makes die head in continuous flow procedure keeps within the specific limits, oily cooling back installation 4 must be set in the die head both sides lead to oil cooling but, make die head temperature keep within the specific limits.Through verification experimental verification, when temperature during at 130 ℃-140 ℃, the surface has irregular pattern 5 to occur, and decorative pattern becomes coarse when temperature is low, and when temperature was high, it is smooth that the surface becomes, so 130 ℃-140 ℃ of preferential selections.
