Description

[Technical Field] The present invention relates to a moisture-proof insulating material for an electronic component excellent in workability and quick-drying property, and an electronic component insulated by the moisture-proof insulating material. [Prior Art] In the manufacturing process of an electronic device, an insulating film can be applied for the purpose of protecting a metal exposed portion such as a package board or an electrode from moisture, dust, or a corrosive gas. The coating material may be of a UV curable type, a moisture curable property, a solvent-drying type or the like, and an acrylic resin, a polyoxymethylene resin, a styrene block copolymer resin or the like may be used. The moisture-curing coating material is a polyoxyxene resin which is excellent in moisture resistance, but has moisture permeability. Therefore, in order to protect the metal of the circuit or the electrode, there is a problem that it is necessary to apply a very thick coating material. The ultraviolet curable coating material is widely used because it can be hardened in a short time and is excellent in productivity. For example, a polyolefin polyol described in JP-A-2007-30868, or a urethane derived from a polycarbonate polyol described in JP-A-2007-332279, is known. Modified acrylate compound and the like. In the manufacturing step of the electronic device, if any defect occurs after the coating treatment with the moisture-proof insulating material is confirmed, the repairing step of re-bonding the new part is removed by removing the defective part. When the parts are re-bonded in this repair step, it is difficult to position the UV-irradiated -5-201247798 due to the uncertainty of the defective part, and the solvent-drying type coating material is often used. A solvent-drying type composition for a coating material is disclosed in JP-A-2003-145687, which discloses a composition comprising a styrene-based thermoplastic elastomer, a tackifier, and toluene. However, it is advisable to use a solvent which is less than toluene in terms of toxicity or environment. A styrene-based thermoplastic elastomer, which is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. A composition comprising a tackifier, a decane coupling agent, and ethylcyclohexane. However, in the solvent containing ethylcyclohexane as a main component, the drying property is accelerated, and when the solid content concentration is increased, the viscosity of the composition is increased, and as a result, the workability (i.e., the gel performance) is lowered. Further, when the viscosity is low, if the amount of ethylcyclohexane is increased to form a film thickness after drying at about 1 3 0 // m, it takes 5 minutes or more from room temperature to the time when the stickiness disappears. Happening.

S -6 - 201247798 [Summary of the Invention] [Problems to be Solved by the Invention] The solvent-drying type coating material is required to exhibit physical properties required for coating/drying only because the curing reaction is not accompanied. Therefore, it is necessary to increase the molecular weight of the resin. However, the higher the molecular weight of the resin, the higher the viscosity of the coating material, the lower the workability, or the workability, and if the coating material is diluted, the thickness of the coating film after application and drying becomes thin, and the moisture resistance is poor. Further, after the application, the time until the adhesion of the surface of the coating film disappears becomes long, which causes a problem of low productivity. For the efficiency of the step, the solvent-drying type coating material is preferably moved to the following step at a time of 3 minutes or less after the coating to seek quick drying property. However, if the drying is too fast, the dispensing property may cause stringiness in the dispensing liquid, and in the case of serious clogging at the front end of the cylinder, it is necessary to have a moderate dryness. [Means for Solving the Problems] The inventors of the present invention have found that the solvent-dried coating material containing a styrene-based thermoplastic elastomer has a temperature of 80 ° C or higher.

The thermoplastic compound has the same molding process, and has a polymer compound exhibiting rubber elasticity (that is, significant elastic recovery) at room temperature. In detail, it has been described in the Physical Chemistry Dictionary Committee, "The Thermoplastic Elastomer".

The best system is 1 9 to 4 3 mass%. When the content of the structural unit derived from styrene contained in the styrene-based thermoplastic elastomer is less than 15% by mass based on the total amount of the styrene-based thermoplastic elastomer, the cohesive force of the elastomer may be insufficient. It's hard to say good. In addition, when the total amount of the styrene-based thermoplastic elastomer is more than 50% by mass, the rubber property of the elastomer tends to disappear, and the tendency of the moisture-proof performance is insufficient, which is difficult. The tackifier used in the present invention is formulated to have rubber elasticity

The elastomer of S -12- 201247798 is a polymer compound represented by an elastomer and has an adhesive function. Compared with a polymer compound represented by an elastomer, the molecular weight is extremely small, and a compound in the field of oligomers having a molecular weight of several hundred to several thousands generally has a property of not exhibiting rubber elasticity at room temperature in a glass state. As the tackifier, a petroleum resin tackifier, a terpene resin tackifier, a rosin resin tackifier, a coumarone terpene resin tackifier, and a styrene resin tackifier can be used.

With film strength. Further, when the solid content concentration is lowered, the time until the adhesion of the surface of the coating film after application disappears becomes long, and as a result, productivity may be lowered. Further, when the total blending amount of the styrene-based thermoplastic elastomer and the tackifier is more than 40% by mass based on the total mass of the moisture-proof insulating material, the viscosity of the coating material becomes high and workability is poor, and it is difficult to apply uniformly. Cloth, when the glue is glued, sometimes the tube is clogged, which is hard to say. The blending ratio of the styrene-based thermoplastic elastomer to the tackifier is in the range of 2:1 to 10:1, preferably 2.5:1 to 9.5:1, more preferably 3:1. The range of 9:1. When the blend ratio of the styrene-based thermoplastic elastomer to the tackifier is more than 10:1 by mass ratio, it may not be sufficient to exhibit sufficient adhesive function. Further, when the blend ratio of the styrene-based thermoplastic elastomer to the tackifier is less than 2:1, the tensile strength of the film after coating drying is remarkably lowered. As a result, when the moisture-proof insulating film is removed by removing the moisture-proof insulating film by removing the defective part and re-bonding the new part, the moisture-proof insulating film is cut off and cannot be removed as one film. good.

Examples of the solvent composed of the dialkyl carbonate represented by the formula (1) include, for example, dimethyl carbonate. , ethyl methyl carbonate 'diethyl carbonate. Among these, in consideration of the balance between the quick drying property and the stringiness, diethyl carbonate is preferred.

After coating the moisture-proof insulating material, if the drying property and workability under the condition of no wind at room temperature are considered, the boiling point should be 14 ° C or less, specifically n-butyl acetate, isobutyl acetate, acetic acid The acetate solvent such as tributyl ester, isopropyl acetate, ethyl acetate or n-propyl acetate is more preferably n-propyl acetate, isobutyl acetate, tert-butyl acetate or n-butyl acetate. -16- 201247798 The total amount of the solvent contained in the moisture-proof insulating material is preferably 60 to 80% by mass, more preferably 65 to 78% by mass, most preferably 70 to 76% by mass based on the total mass of the moisture-proof insulating material. %. If the total amount of the solvent is too large, the thickness of the coating material is too thin, and sufficient moisture resistance and film strength may not be obtained. Further, as the solid content concentration becomes lower, the time until the adhesion of the surface of the coating film after application is shortened becomes longer, and as a result, the productivity is sometimes lowered. On the other hand, if the total amount of the solvent is too small, the viscosity of the coating material becomes high and the workability is poor, and it is difficult to apply it uniformly, or when the dispenser is dispensed, the cartridge may be clogged.
