Description
Technical field
the present invention relates to plastics and extrude processing technique field, are resistant to bending color coextrusion section bars of a kind of reflected infrared and preparation method thereof.
Background technology
color coextrusion door-window section bar generally is co-extruded by two kinds of materials; Base material is the PVC material; A side is passed through co-extrusion method at surperficial co-extrusion one deck colored plastic layer outside the faced chamber; Two kinds of materials are combined with each other under through dedicated co-extrusion mold heated molten state, process the color coextrusion plastic door-window section bar of various colors.The thermal expansivity of macromolecular material is bigger than metallic substance; And the thermal expansivity of macromolecular material increases along with the raising of temperature; The thermal expansivity of different macromolecular materials also there are differences, and the base material of color coextrusion plastic door-window section bar and the thermal expansivity of coextruded layer just there are differences.The door and window that this color coextrusion plastic door-window section bar is processed is owing to the infrared ray radiation in the sun exposure, particularly daylight, and the difference of being heated inside and outside the window is big; Cause the coextruded layer thermal expansion in base material and the outside of inboard of color coextrusion plastic door-window section bar different; The color coextrusion plastic door-window section bar is occured bending and deformation, and particularly dark color coextrusion plastic door-window section bar is because it is more to absorb infrared rays; Diastrophic degree is bigger, and serious meeting influences the sealing property and the work-ing life of door and window.
Summary of the invention
the invention provides resistant to bending color coextrusion section bar of a kind of reflected infrared and preparation method thereof; Overcome the deficiency of above-mentioned prior art; It can effectively solve existing color coextrusion PVC door-window section bar, and the door and window that particularly dark color coextrusion PVC door-window section bar is processed influences the problem in stopping property and work-ing life owing to sun exposure flexural deformation.
One of
technical scheme of the present invention realizes through following measure: the resistant to bending color coextrusion section bar of a kind of reflected infrared: contain 100 parts of vinylformic acid-styrene-propene eyeball multipolymer or polymethylmethacrylates by weight; 0 to 110 part of PVC; 5 parts to 16 parts of stablizers; 1 part to 12 parts of processing aid; 5 parts to 25 parts of impact modifiers; 1 part to 70 parts of potassium titanate crystal whisker after silane coupling agent is handled.
Two of
technical scheme of the present invention realizes through following measure: the preparation method of the resistant to bending color coextrusion section bar of a kind of reflected infrared: undertaken by following step: the first step: under the high-speed mixer low speed state, vinylformic acid-styrene-propene eyeball multipolymer or polymethylmethacrylate and PVC and stablizer are joined in the high-speed mixer, then under the high-speed mixer high-speed state to adding material heat and make temperature of charge reach 60 ℃ to 80 ℃; Second step: the potassium titanate crystal whisker after under the high-speed mixer high-speed state, again processing aid, anti-impact modifier and silane coupling agent being handled joins the temperature of charge that continues in the high-speed mixer to be heated in the high-speed mixer and reaches 110 ℃ to 130 ℃; Under the high-speed mixer low speed state, the material in the high-speed mixer is drained in the low speed mixer that is rotating and lowers the temperature; Treat that material temperature drops to 35 ℃ to 55 ℃ in the low speed mixer, material is discharged from low speed mixer obtain special-purpose dry blend then; The 3rd step: in special-purpose dry blend adding tablets press, through the tablets press heating and melting extrude, cutting and refrigerating work procedure, obtain the counter-bending colored pellet of reflected infrared; The 4th step: the counter-bending colored pellet of reflected infrared is added heating and melting in single screw rod co-extrusion machine; The PVC dry blend that adds processing aid is added heating and melting in the twin screw extruder; Two kinds of melting materials are combined with each other under molten state through the dedicated co-extrusion mould, process the resistant to bending color coextrusion section bar of reflected infrared.
the present invention obtains the counter-bending colored pellet of reflected infrared through the dry blend that is added with the potassium titanate crystal whisker after silane coupling agent is handled; The counter-bending colored pellet of reflected infrared is processed the resistant to bending color coextrusion section bar of reflected infrared with the PVC siccative that adds processing aid through the dedicated co-extrusion mould; The color coextrusion door and window of processing with the resistant to bending color coextrusion section bar of reflected infrared; Have reflected infrared function, heat insulating function and enhancing resistance to deformation function; Under ultrared effect, reduced the amplitude of color coextrusion door and window temperature distortion; Improve the work-ing life of color coextrusion door and window, avoided the reduction of color coextrusion doors and windows sealing performance.
