Embodiment 1
[0022]The material is first mixed, and the process method is substantially the same as the existing mixing method, and a uniform dry mixture is mixed from a high-speed mixer and a cooling mixer, and the specific process is as follows.
[0023](1) 100 parts of PVC resin, 2.5 parts of stabilizer thiolmetin, 181,18 parts of the plasticizer to terephthalate during rotation of high-speed mixer;
[0024](2) When the temperature of the high-speed mixer is raised to 75-80 ° C, 25 parts of ACR-G-VC copolymer resin, 15 thermoplastic elastomers TPVC, 0.8 parts of lubricant RGH-4; TPVC has traditional cross-linking High elasticity, aging resistance, and oil resistance of the vulcanized rubber, and the compatibility with PVC is better, and also has the characteristics of convenient ordinary plastic processing, the processing method is wide, and it is convenient for extrusion, blow molding. The return flexibility is greatly stretched, but the amount of addition is too large, the stiffness and intensity...
Embodiment 2
[0031]Embodiment 2 is generally the same as the technical solution of the first example, and the difference is the composition of the component:
[0032]All of the components are: 100 parts of the PVC resin, 28 parts of the ACR-G-VC copolymerization resin, 12 parts of TPVC thermoplastic elastomer, 181 2.3 parts of the stabilizer thioliometry, 2 plasticizer 2 19 parts of octyl, internal lubricant RGH-40.8 parts, 0.3 parts of the outer lubricant polyethylene wax, and 1.5 parts of the antifogramine monostearate.
[0033]Finally, a sleeve label film having a thickness of 0.025 mm was performed, and the lateral tensile strength was 29.3 MPa, and the longitudinal tensile strength was 42.4 MPa; its transverse fracture elongation was 862.1 MPa, and the longitudinal fracture elongation was The lateral tear strength is 667.8 MPa, and the longitudinal tear strength is 272.1 MPa; the haze is 3.3%.
Embodiment 3
[0035]All of the ingredients are: 100 parts of the PVC resin, 30 parts of the ACR-G-VC copolymerization resin, 10 parts of TPVC thermoplastic elastomer, 181 2 parts of the stabilizer thiometry tin, and 2 plasticizers. 20 parts of octyl, internal lubricant RGH-41.0 parts, 0.5 parts of the outer lubricant polyethylene wax, and 1.5 parts of the antifogramine monohydrate.
[0036]Finally, a sleeve label film having a thickness of 0.025 mm was performed, and the lateral tensile strength was 28.7 MPa, and the longitudinal tensile strength was 43.4 MPa; its transverse fracture elongation was 860.7 MPa, and the longitudinal fracture elongation was The lateral tear strength is 669.9 mPa, the longitudinal tear strength is 273.4 MPa; the haze is 3.3%.
[0037]As can be seen from the above data, the tensile strength of the cold absorbing label film using the above process process can satisfy the packaging requirements of the small rod shape, columnar or container class such as a certain long-distance...
