Description

本発明は、離型剤に関し、更に詳しくは合成樹脂や合成ゴムなどの成形体を成形する際に使用するのに好適な成形金型用の離型剤に関する。   The present invention relates to a mold release agent, and more particularly to a mold release agent for a molding die suitable for use in molding a molded body such as a synthetic resin or a synthetic rubber.

合成樹脂の成形体や合成ゴムの成形体を成形する際、成形金型から成形体の離型を容易にすることを目的として、成形金型の内表面に離型剤が塗布される。使用される離型剤としては、たとえばワックス系離型剤やシリコーン系離型剤が広く知られているが、エポキシ樹脂やウレタン樹脂などの接着力の強い材料を使用して成形体を成形する場合には、成形金型に厚く塗布しないと十分な離型効果が得られず、寸法精度の悪化やコストの上昇などの問題点がある。これらの問題点を解決するものとして、フッ素系離型剤であるパーフルオロアルキル基含有リン酸エステル又はその塩などの化合物が知られている。しかし、実際にはこの化合物単独で離型剤として使用することは困難であり、界面活性剤やシリコーンオイル、フッ素オイルなどを有効成分として添加して用いることが多い。それらのフッ素系離型剤は、良好な離型性を有し、また離型寿命も従来のものよりも長いとされているものの、昨今の成形体の形状複雑化に伴い、離型剤としてのなお一層の性能の向上が求められている。   When molding a synthetic resin molding or a synthetic rubber molding, a mold release agent is applied to the inner surface of the molding die for the purpose of facilitating the release of the molding from the molding die. For example, wax-based mold release agents and silicone-based mold release agents are widely known as mold release agents, but a molded body is molded using a material having a strong adhesive force such as an epoxy resin or a urethane resin. In some cases, a sufficient mold release effect cannot be obtained unless the mold is applied thickly, resulting in problems such as deterioration in dimensional accuracy and increase in cost. In order to solve these problems, compounds such as perfluoroalkyl group-containing phosphate esters or salts thereof, which are fluorine-based release agents, are known. In practice, however, it is difficult to use this compound alone as a release agent, and surfactants, silicone oils, fluorine oils and the like are often used as active ingredients. Although these fluorine-based mold release agents have good mold release properties and have a longer mold release life than conventional ones, as the shape of the molded body has become more complex, There is a need for further improvement in performance.

Examples of the co-monomer include ethylene, vinyl acetate, vinyl chloride, vinyl fluoride, vinylidene halide, styrene, methylstyrene, (meth) acrylic acid and esters thereof, (meth) acrylamide monomers, Examples include (meth) allyl monomers. In a general release agent composition, if the ratio of (meth) acrylic acid-modified silicone oil is too high, transfer becomes easy, and if the fluorine content in the skeleton of the copolymer compound is too high, the solubility is extremely high. It may be lowered. Therefore, it is desirable to mix these materials as appropriate according to the solvent and concentration used and the resin to be molded. For example, by replacing a part of the (meth) acrylic acid-modified silicone oil with a long-chain compound such as lauryl or stearyl, it is possible to suppress the transfer of the release agent while maintaining the release property. For the purpose of improving durability, a monomer having an active group capable of adsorbing to the mold, for example, an amino group, a carboxyl group, a sulfonic acid group, a phosphoric acid group, or a silane group may be added as appropriate. it can.

In addition to thermal polymerization, photopolymerization, energy beam polymerization, and the like can be employed. As the polymerization initiator, polymerization initiators such as existing organic azo compounds, peroxides, persulfates and the like can be used.
