PVC thermoplastic material heat-resistant modifier

Abstract

The invention relates to the technical field of plate processing equipment, and discloses a PVC thermoplastic material heat-resistant modifier which comprises a punching and riveting clamp body, the middle of the bottom end of the punching and riveting clamp body is in threaded connection with a lower die, and a pressure spring is movably connected to the bottom of the outer surface of a supporting connecting rod and located between a fixed base plate and a positioning pressing plate in a sleeving mode. According to the PVC thermoplastic material heat-resistant modifier, due to the arrangementof the two sets of supporting rollers, an aluminum plate can be clamped, it is ensured that the aluminum plate to be riveted can be kept in a horizontal state, and a rivet can be kept perpendicular to the aluminum plate when pressed; the situation that due to oblique piercing of the rivet, stress is uneven during compression plastic deformation, and consequently the connecting strength during riveting is low is avoided, meanwhile, the thickness of the aluminum plate can be fed back to the self-adaptive sleeve, the liquid level height of shear thickening liquid in the self-adaptive sleeve canbe adjusted, and therefore the pressure and stroke parameters of the punching and riveting device are adjusted and controlled.

Description

technical field [0001] The invention relates to the technical field of auxiliary materials for PVC production, in particular to a heat-resistant modifier for PVC thermoplastic materials. Background technique [0002] In the production process of PVC thermoplastic materials, there is a phenomenon that common PVC thermoplastic materials do not have heat resistance during use, which makes the phenomenon of insufficient heat resistance during use. In the production process, a modifier is added to the interior of the PVC thermoplastic material to drive the PVC thermoplastic material to produce heat resistance. For this reason, a heat-resistant modifier for the PVC thermoplastic material has been developed. [0003] However, there are certain problems in the production process of the existing heat-resistant modifiers for PVC thermoplastic materials. Therefore, it is necessary to improve the existing heat-resistant modifiers for PVC thermoplastic materials. Heat-resistant modifier...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a heat-resistant modifier for PVC thermoplastic materials, which has the advantages of being convenient for cooling and drying the reacted materials and mixing with liquid in the later stage, so that it is convenient for mixing with PVC thermoplastic materials, and solves the problem of common PVC heat-resistant modifiers. The heat-resistant modifier of plastic materials is a powder device, which is difficult to adjust to a suitable consistency for mixing and difficult to dry during the production process.
