Description
Technical Field
The invention belongs to the technical field of general plastics, and particularly relates to a polyvinyl chloride composition and a preparation method and application thereof.
Background
The chlorine content of the polyvinyl chloride material is up to more than 56%, so that the resin has stronger polarity, and the surface energy of the pure PVC resin is up to 33dynes/cm, thus the PVC resin has better printing property and self-bonding property. The surface energy of the plasticized polyvinyl chloride composite material is reduced from 33dynes/cm to about 20dynes/cm and even lower due to the introduction of a large amount of plasticizer, so that the printability and the self-adhesive property of the material are greatly lost, and the difficulty of selecting materials is increased for the finished product of the plasticized polyvinyl chloride composite material in the secondary processing stage.
Under the existing technical conditions, when the plasticized polyvinyl chloride composite material finished product is processed for the second time, in order to pursue the relatively safe bonding strength, the plasticized polyvinyl chloride composite material finished product is often realized through glue such as acrylic esters and the like, the production assembly procedure can be increased to a certain extent by the means, and meanwhile, the defect of products can be caused due to the fact that glue is not coated.
Patent document CN201810771194 discloses a modification method for preparing polyvinyl chloride surface with high binding power. The advanced excimer laser is adopted in the patent, through the surface treatment of the workpiece, the microscopic morphology of the PVC material surface is improved, the surface roughness is increased, and the mechanical interlocking of the bonding piece is enhanced; the high single photon energy excimer laser breaks the chemical bond on the PVC surface and forms a new chemical bond favorable for bonding, thereby increasing the bonding strength.
The invention mainly solves the problem that the glue strength of the traditional plasticized soft polyvinyl chloride composite material is insufficient, the hot melt adhesive can be used for bonding PVC sealing strips, the bonding strength is high, the plasticizer exudation in the PVC sealing strips does not affect the bonding performance of the hot melt adhesive at all, and the bonding reliability is obviously improved.
