Problems solved by technology

Due to the relatively high mold temperature, a considerable part will be atomized by high temperature and scattered around, which will cause graphite dust pollution. If people work in an environment with graphite dust for a long time, it will affect people's health and even cause lung cancer.

Abstract

The invention relates to a mould release agent for precision forging forming. The mould release agent comprises the following ingredients in percentage by weight: 8 to 12 percent of silica gel, 35 to 45 percent of aluminum hydroxide, 18 to 22 percent of talc powder, 8 to 12 percent of hibiscus leaf extraction liquid, 2.5 to 3.5 percent of dispersing agents, 2.5 to 3.5 percent of defoaming agents, 3 to 4 percent of stabilizing agents and the balance of water. The mould release agent provided by the invention is applicable to precision forging moulds made of aluminum, copper, steel and iron and the like, a preparation method is simple, the silica gel in the mould release agent has the effect of bonding all ingredients and simultaneously takes neutralization reaction with the aluminum hydroxide, the talc powder and the hibiscus leaf extraction liquid respectively have the effects of lubricating the inner surface of a mould, and have the effects of smoothening the surface of a product, and the hibiscus leaf extraction liquid has the cleaning and lubricating effects. The mould release agent provided by the invention is used on the precision forging mould, is suitable for being used for smoothening the surface of the product, and meets the precision forging requirements, meanwhile, the mould release agent does not contain aquadag, aquadag dust cannot be generated in the use process, the work environment is protected, and the influence cannot be caused on the human body respiration.

Description

technical field [0001] The invention relates to a release agent used in forging industries such as aluminum, copper and steel, in particular to a release agent for precision forging and a preparation method thereof. Background technique [0002] The mold release agent is an important auxiliary material in the forging mold process, and the mold surface molding condition, surface roughness and mold life are closely related to the mold release agent. There are three types of release agents: oily, water-based and solid powder. At present, most of them use water-based emulsion release agents. [0003] In precision forging industries such as aluminum, copper, and steel, it is generally necessary to use graphite emulsion to prepare a release agent and spray it on the mold through a spray gun. Due to the relatively high temperature of the mold, a considerable part will be atomized by high temperature and scattered around, which will cause graphite dust pollution. People who work in...
