Description

Inorganic particle dispersion vehicle composition, inorganic particle dispersion vehicle composition, manufacturing method, inorganic particle dispersion slurry composition, and electronic component manufacturing method

The present invention relates to a vehicle liquid composition for dispersing inorganic particles, a method for manufacturing a vehicle liquid composition for dispersing inorganic particles, an inorganic particle dispersion slurry composition, and a method for manufacturing electronic components.

In recent years, compositions in which inorganic particles such as ceramic powder and glass particles are dispersed in a binder resin have been used to produce multilayer electronic components such as multilayer ceramic capacitors. Such multilayer ceramic capacitors are generally manufactured using the method described below. First, additives such as a plasticizer and a dispersant are added to a solution in which a binder resin is dissolved in an organic solvent, and then ceramic raw material powder is added and mixed uniformly using a ball mill or the like to obtain an inorganic particle dispersion composition. The obtained inorganic particle dispersion composition is cast on the surface of a support such as a release-treated polyethylene terephthalate film or SUS board using a doctor blade, reverse roll coater, etc. After molding, volatile components such as organic solvents are distilled off, and then the ceramic green sheets are peeled off from the support. Next, a conductive paste that will serve as an internal electrode is applied to the obtained ceramic green sheets by screen printing or the like, and a plurality of sheets are stacked, heated and pressure-bonded to obtain a laminated body. A so-called degreasing treatment is performed, that is, the obtained laminate is heated to thermally decompose and remove components such as a binder resin, and is then calcined to obtain a ceramic calcined body equipped with internal electrodes. Furthermore, an external electrode is applied to the end surface of the obtained ceramic calcined body, and the resulting ceramic calcined body is calcined, thereby completing a multilayer ceramic capacitor. In the calcining step, problems such as expansion or cracking of the calcined body are often caused, and it is desired to degrease the binder resin in a short time by using low temperature. Therefore, studies have been conducted on the use of a binder resin that can be calcined at low temperature and has a small residual carbon component after calcining.

For example, in Patent Document 1, it is studied to use paraffin wax or polyethylene glycol to control the degreasing temperature to a lower temperature of 230°C to 350°C. Furthermore, in Patent Document 2, it was studied to improve the removability of the binder resin by using an acrylic resin with an average molecular weight of 2.0×10 ⁵ or more, an acid value of 2.4 to 7.2, and a glass transition temperature of 50 to 90°C as the binder resin. .

However, although the paraffin wax or polyethylene glycol described in Patent Document 1 can be used using a mold such as a stamper, the binder resin itself does not have sufficient strength and cannot be used in processes such as forming thin-film ceramic green sheets. problem. Furthermore, although the method described in Patent Document 2 can achieve degreasing at low temperatures, the degreasing time becomes extremely long, and when used for large-scale ceramic molded products, there is a problem of insufficient internal degreasing.

In view of the above problems, an object of the present invention is to provide a vehicle composition for dispersing inorganic particles that can achieve degreasing at a lower temperature and in a short time and has excellent viscosity stability.

The present invention (5) is a vehicle composition for dispersing inorganic particles in any combination with any one of the present inventions (1) to (4), wherein the (meth)acrylic resin contains more than 40% by weight of Chain segment of isobutyl methacrylate. The present invention (6) is a method for producing a vehicle composition for dispersing inorganic particles, which includes: adding a polymerization initiator to a raw material monomer mixture containing a (meth)acrylic acid ester and a solvent; The step of copolymerizing a raw material monomer mixture to produce a (meth)acrylic resin, the above-mentioned polymerization initiator is an organic peroxide, so that in the presence of the above-mentioned terpene compound, relative to 100 parts by weight of the above-mentioned raw material monomer mixture, the above-mentioned The polymerization initiator is added so that the active oxygen content of the polymerization initiator becomes 0.04 parts by weight or more and 0.3 parts by weight or less. The present invention (7) is an inorganic particle dispersion slurry composition containing the inorganic particle dispersion vehicle composition of any one of the present invention (1) to (5) and the inorganic particles. The present invention (8) is a method for manufacturing electronic components, which includes the step of using the inorganic particle dispersion slurry composition of the present invention (7) and performing degreasing at a temperature of 300°C or more and 400°C or less. The present invention will be described in detail below.

The present inventors discovered that the reason why the degreasing time of the (meth)acrylic resin becomes long is that the thermal decomposition of the (meth)acrylic resin proceeds by the following mechanism. That is, instead of using oxygen in the air to oxidatively decompose cellulose or polyvinyl butyraldehyde resin, in the thermal decomposition of (meth)acrylic resin, the calcining environment temperature is the maximum temperature of (meth)acrylic resin. The above causes a depolymerization reaction, but in this reaction, part of the monomer obtained after decomposition will be oxidized and burned due to heat, and will be decomposed into components with smaller molecular weights. At this time, most of the monomers obtained after decomposition are repolymerized into polymers due to the heat of calcination. Under this mechanism, most of the polymer components after thermal decomposition are polymerized again, so the apparent decomposition speed used to decompose (meth)acrylic resin is slow, resulting in degreasing taking a long time.

Therefore, as a result of diligent research, the present inventors found that by adding a predetermined amount of a specific terpene compound to (meth)acrylic resin, the repolymerization of the decomposed monomers in the degreasing step can be suppressed and the decomposition initiation temperature can be increased. , and increase the apparent decomposition speed, enabling short-term degreasing at low temperatures. Furthermore, it was found that the vehicle composition for dispersing inorganic particles containing such a specific terpene compound also has excellent viscosity stability. Furthermore, they found that by using an inorganic particle dispersion slurry composition containing such an inorganic particle dispersion vehicle composition for the production of ceramic green sheets, voids or cracks caused by resin decomposition gas during degreasing can be effectively prevented, thereby completing the process. of the present invention.
