Description

Aqueous release agent and preparation method thereof

TECHNICAL FIELD This invention relates to a mold release agent. Specifically, It is related with the aqueous mold release agent which can be diluted and used in water.

In general, the mold is applied to the mold release agent as a spray and a brush in order to facilitate the demolding, and most of the existing mold release agents have the following problems.

Usually, a mold release agent uses silicones and waxes, which are diluted with a ignition solvent and applied and used as a brush or a spray on a mold.

The diluent of silicone and wax is a flammable material that is easily ignited with methylene chloride, benzene, Hansol, etc., and has a difficult handling, and is a very harmful ingredient to the human body and the environment.

Such a release agent, in particular in the production process of shoes, had a number of disadvantages such as lowering the productivity of the product because the temperature of the mold is not constant according to the season in the manual mold line.

That is, the mold must maintain an appropriate molding temperature for the molding operation, and by using a conventional oil-based release agent (e.g., a release agent disclosed in Japanese Patent Laid-Open No. 6-344353, etc.), the ignition property is strong and the mold release agent molds the mold. When the mold temperature was lowered by applying a release agent on the mold and the mold temperature was lowered so that it could not be heated properly, the mold heating operation was forced to be performed at any time, and the time required for heating and the heat loss were considerable. Minutes (based on 30 pages), energy consumption about 100,000kcal)

On the other hand, as a chemical for removing foreign matter from the mold, it is removed by using a highly toxic toxic oil (DMF), and the mold is warmed again to an appropriate temperature, thereby causing waste of time and energy. The failure rate of the production reaches an average of 15 to 20%, and there is a difficulty in handling due to the high flammability, which adversely affects workability efficiency.

On the other hand, methylene chloride (especially epoxy resin), which is the most widely used dilution solvent, causes a lot of damage to the earth ozone layer destruction and mold loss, and is quite harmful to the human body.

Therefore, in the present invention, by providing a release agent that can be diluted in water to remove the harmful elements and pollution-causing elements, in particular to remove the ignition to heat to the appropriate temperature to apply the mold on the mold by applying the mold release agent It can be cooled to minimize the time and energy waste of reheating the mold to the proper temperature, and in particular, the benefits and effects of handling the mold.

The present invention is mainly characterized in providing a mold release agent that can be diluted with water in various resin product manufacturing fields such as polyurethane soles, handles, headless, bumpers, hard furniture, sponges, and F.R.P.

The present invention is to prepare a release agent by mixing, dissolving and diluting an emulsifier (TMN-6, SOFMIN 70, NP 100; trade name), silicone, wax, paraffin wax.

Hereinafter, the manufacturing method of the present invention will be described in detail.

EXAMPLE

Component ratio of the present invention based on 1 kg

1) emulsifier

TMN-6 (trimethyl-4-nonyloxy polyethylene oxy ethanol); 20 g

2) silicone (980; trade name); 12g

3) wax; 15 g

4) paraffin wax (PARAFFIN WAX); 75 g

The composition is mixed and reacted and dissolved in a reaction facility.

The reaction temperature is 90 ~ 95 ℃, the time required is about 120 ~ 180 minutes.

The present invention is to be used to dilute purified water in the mixed solution, based on 1kg of the release agent,

Mixed solution 140g: purified water 860g of the mixture is used as a release agent, the mixing ratio of the mixed solution and purified water content of purified water varies depending on the physical properties of the product.

According to the present invention, the mixed solution and purified water are mixed and diluted in a release agent tank in an appropriate ratio in various resin product production lines such as various polyurethane, hard furniture, and FRP, and then applied onto a mold with a spray or a brush. will be.

The present invention as described above can be used to adjust to 10 ~ 100 ℃ according to the product does not have a fire, so that the heat of the mold rises quickly, and when removing the foreign matter of the mold can be heated to about 40 ℃ to perform the cleaning work As a result, the problem of cooling the mold during the cleaning operation is solved as in the prior art, which reduces the time required for cleaning the mold and improves the quality of the product by using a release agent heated to an appropriate temperature, especially in the manufacturing process of the shoe sole. Of course, the defect rate can be reduced to 2 to 3%, and the occurrence of residue blisters is eliminated. As described above, the present invention is a release agent, which is harmless to the human body, is not flammable, and also helps to prevent environmental pollution. Benefits and effects can be obtained.
