Embodiment 1

[0093] Preparation of the wax-injected plug in Example 1-1: The raw material PVC glue is the bottom material of the threshold PVC; prepare a 20wt% zinc oxide suspension, apply it evenly on the inner surface of the iron plug mold, and heat it in an oven at 120°C Dry for 2 hours to obtain a mold covered with zinc oxide layer; install the PVC glue into the mold, shake it firmly, scrape off the excess PVC glue and smooth the surface; put it in an oven at 150°C, dry for 3 hours, cool and demould to get wax injection gag.

[0094] Preparation of the wax-injected plug of Example 1-2: The raw material PVC glue is the bottom material of threshold PVC; prepare 20wt% zinc oxide suspension, apply it evenly on the inner surface of the iron plug mold, and heat it in an oven at 120°C Dry for 2 hours to obtain a mold covered with zinc oxide layer; install the PVC glue into the mold, shake it firmly, scrape off the excess PVC glue and smooth the surface; put it in an oven at 150°C, dry for 5 h...

Embodiment 2

[0108] The raw materials are the bottom of the threshold PVC (PVC glue) and the plasticizer diisononyl phthalate. Mix PVC glue and plasticizer at a mass ratio of 9:1, mechanical stirring speed is 100r / min, stir for 30min, stand still and shake alternately 3-5 times to obtain PVC-10 with evenly mixed PVC glue and plasticizer % Dinp raw material.

[0109] Prepare a 20% by mass zinc oxide suspension, apply it evenly on the inner surface of the iron plug mold, and dry it in an oven at 120°C for 2 hours to obtain a mold covered with a zinc oxide layer. Put the PVC-10%Dinp raw material into the mold, shake it, scrape off the excess raw material and smooth the surface. Put it in an oven at 150°C, dry for 5 hours, cool and demould to obtain a wax injection plug, which is easy to demould. Wrap the wax injection pipe and plug fixing components with tin foil, install the PVC material wax injection plug, and the plug is easy to disassemble.

Embodiment 3

[0111] The raw materials are the bottom of the threshold PVC (PVC glue) and the plasticizer diisononyl phthalate. Mix PVC glue and plasticizer at a mass ratio of 92:8, mechanically stir at a speed of 100r / min, stir for 30min, stand and shake alternately 3-5 times to obtain PVC-8 with evenly mixed PVC glue and plasticizer % plasticizer raw material.

[0112] Prepare a 20% by mass zinc oxide suspension, apply it evenly on the inner surface of the iron plug mold, and dry it in an oven at 120°C for 2 hours to obtain a mold covered with a zinc oxide layer. Put the PVC-8%Dinp raw material into the mold, shake it, scrape off the excess raw material and smooth the surface. Put it in an oven at 150°C, dry for 5 hours, cool and demould to obtain a wax injection plug, which is easy to demould. Wrap the wax injection pipe and plug fixing components with tin foil, install the PVC material wax injection plug, and the plug is easy to disassemble.

Abstract

The invention relates to a PVC material and a preparation and molding method thereof. The PVC material comprises the following raw materials: PVC waste produced during automobile manufacturing and a plasticizer. A wax injection plug made of the PVC material has the advantages of low cost, long service life, good sealing effect and the like, and can replace an existing polyurethane foam plug. The PVC material provided by the invention realizes reutilization of the PVC waste produced during automobile manufacturing.

Description

technical field [0001] The invention belongs to the field of auxiliary materials for automobile production, and in particular relates to a wax-injected plug made of PVC waste used in automobile manufacturing and a preparation method thereof. Background technique [0002] PVC body sealing and inner cavity wax injection are two key processes for automobile anti-corrosion. Among them, the main function of PVC process is to seal the body sheet metal without water leakage, so as to improve its anti-corrosion performance; the wax injection process is to inject wax liquid into the body cavity to form a A dense wax film can effectively improve the anti-corrosion performance of the inner cavity of the sheet metal without paint protection, and eliminate the possibility of corrosion from the inside. [0003] When injecting wax, it is necessary to use a plug with certain strength, elasticity and high temperature resistance to seal the process hole at the bottom of the vehicle to ensure ...
