Abstract

PURPOSE:To prevent the generation of the retention of a resin, curing of which has advanced, in a mixing vessel by pushing a valve body open by a non-curing liquid and injecting a curing liquid into the mixing vessel when the other liquid is injected into the mixing vessel while one liquid of two-part cured resins is made to flow into the mixing vessel. CONSTITUTION:A resin being force-fed from a supply path 12 is fed into a mixing vessel 10 from an inflow port 14, and made to flow into an outflow port 16 by the pressure of the resin force-fed successively. On the other hand, a solvent force-fed through a solenoid valve 38 by a pump 42 pushes the valve body 32 of a check valve 30 open first and is injected from a filler hole 28. The solvent is injected into the mixing vessel 10 from the filler hole 28, the solenoid valve 38 is changed over instantaneously, and a curing agent force-fed by the pump 40 is poured into the mixing vessel 10 in place of the solvent. When the curing agent is injected, the curing agent more than required is not poured at a breath because the valve body 32 of the check valve 30 is pushed open previously by the solvent, and the curing agent is injected under a stable state.

These two-component curable resins are two-component, for example, when a curing agent is mixed with the resin, the resin gradually reacts and the viscosity increases (hardening begins), eventually making it impossible to mold the resin. The time from when these two liquids are mixed until they can no longer be molded is called the pot life (pot life), and the pot life may be longer or shorter depending on the temperature, the mixed concentration of the two liquids, etc. In order to mold a resin molded product within this pot life, a continuous mixing device is placed in close proximity to the molding machine, and this continuous mixing device continuously mixes the two liquids and supplies the mixture to the molding machine. .

In order to mix the two components uniformly and quickly without generating air bubbles, the continuous mixing device continuously supplies one component of the two-component curing resin, such as resin, into a mixing container and stirs it. , another liquid, for example, a curing agent, is injected into the mixing container by pushing open the valve body of the check valve, which is energized by the urging means, with the injection pressure of the curing agent, thereby mixing the resin and the curing agent. Apparatus is provided for continuous mixing.

However, at the time of startup, as shown in Figure 5, the injection pressure of the curing agent increases against the biasing force that biases the valve body.
After a certain peak value is reached and the valve body is pushed open, the pressure decreases while repeating up and down movements up to the pressure during steady operation, and then stabilizes at a nearly constant value.

At the start of operation when the valve body is pushed open, more hardening agent than the required amount is injected into the mixing container at once, resulting in a high mixed concentration of hardening agent. The pot life of the two highly concentrated mixed liquids has elapsed by the time they are discharged from the mixing container, and this hardened resin may remain in the mixing container and adhere thereto. The hardened resin is cut into small pieces by the stirring blades and gradually discharged, so if these foreign substances affect the quality of the molded product, the entire molded product may be defective. .

According to the method of the present invention, when one part of the two-component curable resin is poured into the mixing container while the other part is injected into the mixing container, the first part is first separated from the other by a non-curing liquid. The valve body of the reversal valve is pushed open. Therefore, a large amount of non-hardening liquid is injected into the mixing container at once against the urging force applied to the valve body, but this non-hardening liquid causes one liquid to flow into the mixing container. Since the liquid is not cured, the liquid and the non-curable liquid are discharged from the mixing container in a mixed or separated state. The non-curing liquid pushes open the valve body of the check valve and in a stable state, the curable liquid is injected into the mixing container after the non-curing liquid, so more curable liquid is injected than the required amount. It will not be done.

Of the two liquids discharged from the mixing container, a certain amount of the part into which the non-hardening liquid was injected will be discarded, but the hardened resin will be cut into small pieces, which can cause defects in molded products. A situation where the liquid is gradually discharged will not occur.

In the present invention, when continuously mixing two-component curable resins, the valve body of the check valve is pushed open with a non-curing liquid, and then the curable liquid is pumped into the mixing container. Since the liquid is injected into the mixing container at once when the valve body is opened, the curing of the two-component curing resin is not accelerated. There is no possibility that the two-component curing resin that has been mixed continuously by the method of the present invention will be stagnated and adhered, and the resin will not be cut into small pieces and gradually discharged from the mixing container. If a resin molded product such as a film is formed using the resin molded product, it becomes possible to provide a product with excellent surface condition and properties, and furthermore, has a low internal defect and is free from internal defects.
