Abstract
A disclosed green environment-friendly water-base mold release agent is characterized by comprising the following raw materials in parts by weight: 5-20 parts of paraffin, 5-8 parts of stearic acid, 5-10 parts of plant oil, 5-8 parts of a co-emulsifier, 2-3 parts of potassium hydroxide, 0.5-1 parts of ethylparaben, and 80-100 parts of deionized water. The mold release agent is simple and practical in formula, and pure green and environment-friendly in raw materials. Additionally, the water-base mold release agent gives play to lubrication effect at a high temperature, also avoids washing effect of a metal liquid on a cavity surface, helps to improve working conditions of a mold, and is capable of avoiding sticking to the mold, reducing the thermal conductivity of the mold and mold temperature, and adjusting the temperature of all parts of the mold to reach a relatively stable state, so that the formability is improved, and a formed film is capable of reducing friction and wearing between a casting and the mold cavity and especially the core, and prolonging the service life of the mold.
Description
Technical field
The present invention relates to mould manufacturing field, relate in particular to a kind of aq. type releasing agent of environmental protection.
Background technology
Releasing agent (mold discharging agent) is a kind of functional substance between mould and finished product.Releasing agent has chemical resistant properties, not dissolved in the time contacting with the Chemical Composition (particularly vinylbenzene and amine) of different resins.Releasing agent also has heat-resisting and stress performance, is difficult for decomposing or wearing and tearing; Releasing agent is adhered on mould and does not transfer on processed product, does not hinder and sprays paint or other secondary machining operation.Due to injection moulding, extrude, the developing rapidly of the technique such as calendering, mold pressing, lamination, the consumption of releasing agent also improves significantly.Existing general releasing agent is environmental protection not mostly, and the efficiency using is not high.Based on this, the releasing agent of a kind of more high-efficiency environment friendly of existing necessary research is to solve an existing difficult problem.
