Definitions
- the present invention is a composite plate of a zirconia sintered body having scratch resistance and impact resistance and a substrate having a specific elastic modulus or a zirconia sintered body and a group consisting of tempered glass, bakelite, aluminum and magnesium.
- the present invention relates to a composite plate with a substrate composed of at least one kind and a method for producing them.
- the material currently used is tempered glass tempered by ion exchange.
- a reinforced layer of about several tens of ⁇ m is generated on the glass surface by ion exchange, and compressive stress is generated on the surface to prevent the development of scratches.
- the strengthening mechanism of tempered glass is derived from the tempered layer, it immediately breaks when a scratch exceeding the tempered layer enters.

実施例14と同様の方法にて3YS20Aの32mm×25mmの複合プレートを製造し、二軸曲げ強度を測定した。曲げ強度は940MPa程度の高い値であることがわかった。試験における荷重-変位曲線から曲げ弾性率を見積もると、80GPa程度であり、いずれも強化ガラス(70GPa)と同程度の弾性率であることがわかった。
実施例22
3YS20Aを用い、実施例1と同様の方法で、ジルコニア質焼結体厚み/強化ガラス厚みの比率を0.09にしたものを製造した。結果を表4に示す。複合プレートは高い耐衝撃性を示すものの、ビッカース硬度は800となり、耐擦傷性は少し低いものであった。
実施例23
TZ-3YS粉末を700g、分散剤として市販のポリカルボン酸エステル型高分子分散剤14g、消泡剤として市販のポリエチレングリコールモノ-パラ-イソ-オクチルフェニルエーテル3.5g、溶剤として酢酸エチル245g及び酢酸n-ブチル245g、結合剤としてブチラール樹脂(重合度約1000)粉末49g、及び可塑剤として、工業用のフタル酸ジオクチル42gを添加してボールミルにて48時間混合した。ドクターブレード装置およびブレードを使用しキャリヤーフィルムとしてPETを使用し、キャリヤーフィルム上にグリーンシートを成膜した。
比較例1
3YS20Aを用い、実施例1と同様の方法で、ジルコニア質焼結体厚み/強化ガラス厚みの比率を1.66にしたものを製造した。結果を表4に示す。複合プレートの見かけの密度は4.3g/cm3を超えた。
比較例2
3YS20Aを用い、実施例1と同様の方法で、接着材なしの条件で鋼球落下試験を行った。結果を表4に示す。接着せずガラスに直置きしてある場合、3cm程度で破壊し、耐衝撃特性は著しく低いことが分かった。
比較例3~5
厚みの異なるアルミノシリケート系の強化ガラス(32mm×25mm、厚み0.55mm、0.7mm、1.1mm)の表面に対して、実施例15と同じ方法で加傷処理を行い、加傷前後の耐衝撃性を評価した。結果を表5に示す。0.55mmについては、加傷処理により母材が割れ、0.7、1.1mmの強化ガラスについては、加傷によって鋼球破壊高さは、半分程度となった。
比較例6、7
ジルコニア質焼結体の代わりにサファイヤ単結晶(株式会社オルベ・パイオニア製)(32mm×25mm)を用いて実施例1と同様の方法で複合プレートを作製し、同様の条件で鋼球落下試験を行った。結果を表7に示す。ここでサファイヤの密度は、3.99g/cm3とした。
実施例24~28
3YS20Aを用い、実施例1と同様の方法で、基材として、アルミニウム(97wt%)-マグネシウム合金(Eggs社製、#5052)、マグネシウム(90wt%)-アルミニウム-亜鉛合金(エムジープレシジョン株式会社製、商品名「AZ91D」)、布ベークライト、紙ベークライト(株式会社扶桑ゴム産業製)をそれぞれ用いて32mm×25mmの複合プレートを作製した。
