Embodiment Construction

[0022] A process for repairing pits on a forming mold is characterized in that it comprises the following steps:

[0023] (1) Polish the damaged mold surface with fine sandpaper that is easy to buy in the market, and clean the repaired surface with ethanol;

[0024] (2) Configure the repair agent, configure the adhesive and aluminum powder in a mass ratio of 1:2, and mix them evenly;

[0025] The binder includes a resin mixture and a curing agent, and the weight parts of the raw materials of the resin mixture are:

[0026] Polyimide 30

[0027] Vinyl polysilazane resin 20

[0028] Silicone modified polyether rubber 12

[0029] Diethylenetriaminopropyltrimethoxysilane 5

[0030] Nano calcium carbonate powder 5

[0031] Aniline methyl triethoxy silane 3

[0032] The above raw materials are mixed and heated for 150-160 to melt, and then stirred at a high speed to obtain a resin mixture; the curing agent is diethylene triamine, and the use mass ratio of the resin mixture and the amine curing age...

Abstract

The invention discloses a repairing process of pits on a forming mold. The repairing process comprises the following operating steps of: carrying out grinding, cleaning, preparation of a repairing agent, coating of the repairing agent, and regrinding on the positions of the pits on the mold. The repairing process disclosed by the invention has the advantages that the process is simple, the operation is easy, the pits on the surface of the mold caused by improper operation and long-time use can be fast repaired, and the outer processing cost is saved.

Description

technical field [0001] The invention relates to a method for repairing large-area defects or pits of forming molds in the production of corrugated pipes. Background technique [0002] During the production of corrugated pipes, due to improper operation or tooling, the mold is damaged in a large area and the surface of the mold is pitted due to long-term use, so that it cannot be used. If a new mold is reprocessed and customized, it will consume time, money and labor, and affect production. . In order to solve such problems, our company's technical research team uses the adhesive (modified polyacrylate) and base material (aluminum powder) on the market in a ratio of 1:2 to repair the mold. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a repair process for the pits on the forming mold, which is simple in process, easy to operate, and can quickly repair the pits on the surface of the mold caused by improper oper...
