JWELL- TPO Plastic sheet extruder machine in automobile application
A, TPO automobile interior trim sheet extruder, TPO automobile interior trim sheet production line, TPO automobile interior trim sheet (chart) a TPO auto interior materials, the material from the top down into the surface treated layer 1, bottom surface treatment agent layer 2, TPO layer 3, polypropylene foam layer 4 layer 5 and adhesives. TPO layer 3 add extinction materials and scratch resistant agent and make the scratch resistance of TPO layer 3 itself, is not easy to be scratched, although the surface coating of surface treating agent layer 1 and layer bottom surface treatment agent 2 washed off, TPO layer 3 itself remains the scratch resistance, do not affect beautiful and adornment sex. 2. TPO automotive interior sheet extruder,TPO automotive interior sheet material production line,TPO automotive interior sheet (shown) adhesive layer for polyurethane adhesive. In polypropylene foam layer coated with a thin layer of water on the back four or no benzene, low odor of polyurethane adhesives, polypropylene frame without when used in spray polyurethane glue, only a small amount of polyurethane glue bonding is very good; The effect of double-sided adhesive is far greater than that of single side. Surface treating agent layer 1 is a solvent - based or aqueous polyurethane or polycarbonate. base primer layer 2 is solvent - based or water - based polyurethane or polycarbonate. On the bottom surface treatment agent layer 2 external increase a layer of surface treating agent 1, prevent after a certain number of times or improper cleaning on the surface of the coating layer is easy to fall off, not scratch resistant TPO itself, prone to scratches. In order to avoid this phenomenon, the surface treating agent layer 1 is added, which ACTS as a double protection. Three, TPO automobile interior trim sheet extruder, TPO automobile interior trim sheet production line, TPO automobile interior trim sheet (chart) at the same time, TPO level 3 in coating surface treatment agent layer 1 and layer bottom surface treatment agent 2 before, should first to corona of TPO layer 3 surface, increase the surface energy, can reach more than 42 dyne, when the surface coated with bottom surface treatment agent layer 2 again. Such pretreatment, even without primer coating 2, single-coated surface primer layer 1, can also guarantee the bonding strength of surface primer 1 and TPO layer 3. But in order to avoid in the process of coating covers the problem of incomplete, corona and then added a bottom surface treatment agent layer 2, also improved the bottom surface treatment agent after corona layer 2 and TPO 3 bond strength, indirect improve the product percent of pass. The thickness of polypropylene foam layer 5 is 1.0, 1.5, 2.0, 2.5 and 3.0mm. The width ranges from 550 to 1350mm, and the foaming ratio is 10, 15, 20, 25, and 30 times.Performance TestStandard Clear FormulaCold FormulaSuper polar curtainUnitShore A Hardness75+-565+-565+-5Sh ABrittle PointApprox -35Approx -45Approx -45Degrees CThermal conductivity0.160.160.16W/m.KVicat softening temp.504848℃Specific heat capacity1.61.61.6kj/kg.KFalling Ball Impact Test"-20 No Break"-40 No Break"-50 No BreakDegrees CFlexibility"-20 No Break"-40 No Break"-50 No BreakDegrees CWater Absorption0.20%0.20%0.20%%Tensile Stress340420420%Tearing resistance502828N/mmReaction to FireSelf-extinguishingSelf-extinguishingSelf-extinguishing0FlammabilityInflammableInflammableInflammable0
