Problems solved by technology

[0007] However, if such a resin is used to form a lens by a processing method such as injection molding that melts the resin for molding, then as the temperature is higher than the Tg of the resin, equipment such as molds for resin molding will be easily damaged. Deterioration, or the problem that the resin itself decomposes and cannot be molded
In addition, in terms of the solvent drying method in which the organic solvent solution of the resin is flowed into the mold, there are problems that the shape is easily deformed due to shrinkage of the resin by drying (solvent volatilization, mass reduction), and the resin solution is dried after a long period of time. , production efficiency drops

Embodiment 1

[0247] 22 g of dehydrated toluene and 22 g of cyclohexane were placed in a 100 ml glass pressure-resistant reaction vessel fully replaced with nitrogen, and then 5-butylbicyclo[2.2.1]hept-2-ene obtained in the synthesis example was added. 5.48ml of a dry toluene solution of 50mmol (7.5g), 7.66mol / l bicyclo[2.2.1]hept-2-ene (42mmol). The reaction container was sealed with a rubber seal, ethylene was blown in at 60 ml / min for 12 seconds, and the temperature was raised to 75°C. Then add the toluene solution 0.40ml of 0.0005mol / l palladium acetate, the toluene solution 0.10ml of 0.002mol / l tricyclohexylphosphine, the toluene solution of 0.0005mol / l triphenylcarbonium tetrakis (pentafluorophenyl) borate 0.40ml, start to polymerize. When 45 minutes and 90 minutes elapsed after the start of the polymerization, 0.52 ml of the toluene solution of the above-mentioned bicyclo[2.2.1]hept-2-ene was added respectively, and the polymerization was continued for a total of 3 hours. The conve...

Embodiment 2

[0251]Film A obtained in Example 1 was dried with hot air at a temperature of 80° C. for 10 minutes to remove the solvent, thereby obtaining Film A-2 with a residual solvent of 7.5% by weight. This film was transferred using the same mold and apparatus as in Example 1 at a pressure of 5 MPa and a temperature of 200° C. to obtain Film B-2. Table 1 shows the evaluation results of this film.

Embodiment 3

[0256] (catalyst modulation)

[0257] Palladium acetate and tricyclohexylphosphine were prepared by adding 0.45ml of a toluene solution of tricyclohexylphosphine adjusted to 0.01mol / L to 0.90ml of a toluene solution of palladium acetate adjusted to 0.005mol / L and stirring at room temperature for 1 hour. complex solution.

[0258] (polymerization)

[0259] 670 g of dry toluene, 240 g of dry cyclohexane, 2.65 mol of bicyclo[2.2.1]hept-2-ene, 5-trimethoxy 0.16 mol of silylmethylbicyclo[2.2.1]hept-2-ene and 0.018 MPa of ethylene in partial pressure were stirred, and the internal temperature was adjusted to 70°C. Separately, the prepared complex solution was added, and then 2.2 ml of a toluene solution of triphenylcarbenium tetrakis(pentafluorophenyl)borate prepared to be 0.002 mol / L was added to start polymerization. Add 37mmol, 25mmol, 12mmol, 12mmol 5-trimethoxysilylmethylbicyclo[2.2.1]hept-2-ene at 60 minutes, 90 minutes, 120 minutes, and 170 minutes after the start of polym...

Abstract

The invention provides a method for processing the surface of a resin molding which can easily change a shape of the surface of the resin molding, mold a resin lens or the like without losing productivity and quality, simplify molding equipment, and prevent the resin from oxidizing by lowering molding temperature under the control of a virtual glass transition temperature of the resin by keeping a plasticity-imparting substance such as a solvent remaining in the resin in a fixed amount. The method for processing the surface of the resin molding comprises the steps of changing at least a part of the surface shape of the molding formed of a mixture of the resin and the plasticity-imparting substance of the resin, and then removing or solidifying the plasticity-imparting substance.

Description

technical field [0001] The present invention relates to a surface processing method of a resin molded body, and more specifically, to a surface processing method of a resin molded body used for a surface mount component incorporating an optical material. Background technique [0002] In recent years, the mainstream of the manufacturing method of printed circuit boards is the surface mount method using surface mount components in order to achieve high density and multilayer. Among them, the so-called surface mount components refer to electronic components such as LSIs, resistors, and capacitors that can be mounted on printed substrates using surface mount technology. On these components, wire plugs are led out from the component terminals, or tiny solder materials are pre-attached to the terminal parts so that surface mounting can be performed. In terms of surface mount technology, first, surface mount components are mounted on the surface of a substrate using an injection m...
