ある成形物である。[Means for Solving the Problems] The molded article of the present invention includes a synthetic resin binder, wear-resistant inorganic particles having a large particle size, and wear-resistant inorganic particles having a smaller particle size. , the mixing ratio of the synthetic resin binder and both wear-resistant inorganic particles is 1:1 (5 to 12) by weight, and the large particle size of the wear-resistant inorganic particles is beads with a particle size of 150 μ to 1000 μ. and the particle size of the wear-resistant inorganic particles with a small particle size is 10 μ to 100 μ, and the particle size of the wear-resistant inorganic particles with a small particle size is equal to the particle size of the large wear-resistant inorganic particles. It is a molded article in which the mixing ratio of wear-resistant inorganic particles with a large particle size and wear-resistant inorganic particles with a small particle size is 1:1 (0.1 to 1) by weight.

いと、やはり混練作業を困難にする。 As the large-diameter inorganic particles, beads (spheres) such as mullite, α-alumina, and glass having a new Mohs hardness of 8 or more are used. The particle size of large-diameter inorganic particles is 150μ~
They are 1000μ beads. The reason for this is that if the particle size of the large-diameter inorganic particles becomes too large, the surface quality deteriorates, while if the particle size becomes too small, the abrasion resistance deteriorates, making it easy to get scratched, and the overall The surface area becomes too large and the
This is because it makes it difficult to knead the large-diameter inorganic particles, the synthetic resin binder, and the small-diameter inorganic particles, making uniform mixing difficult. Furthermore, if the large-diameter inorganic particles are not beads, the kneading operation will be difficult.

下する欠点が生じる。 As small-diameter inorganic particles, similar to large-diameter inorganic particles,
Use materials with a new Mohs hardness of 8 or higher, such as mullite, α-alumina, and glass. The particle size of the small-diameter inorganic particles is 10 μ to 100 μ, and is required to be one-third or less, preferably one-fourth or less of the particle size of the large-diameter inorganic particles. The reason for this is that if the particle size of the small-diameter inorganic particles becomes too large, the moldability will deteriorate, and on the other hand, if the particle size becomes too small, a large amount of synthetic resin binder will be required. Furthermore, if the particle size of the small-diameter inorganic particles exceeds one-third of the particle size of the large-diameter inorganic particles, the amount of synthetic resin binder required increases, resulting in a disadvantage that the abrasion resistance decreases.
大径無機粒子と小径無機粒子との混合比は重量

状態となると共に、耐衝撃性、耐汚染性、表面性
状が悪くなるからである。 It is necessary that the mixing ratio of large-diameter inorganic particles and small-diameter inorganic particles is 1:1 (0.1 to 1) by weight.
The reason for this is that if the mixing ratio of small-diameter inorganic particles to large-diameter inorganic particles is less than 0.1 or exceeds 1, moldability and anti-contamination properties will deteriorate, and the porosity of the mixture of both inorganic particles will increase. This is because a large amount of synthetic resin binder is required. The mixing ratio of the synthetic resin binder (solid content) and both inorganic particles is 1:1 (5 to 12) by weight. The reason for this is that if the mixing ratio of both inorganic particles to the synthetic resin binder is less than 5, scratch resistance etc. will deteriorate;
This is because if it exceeds this value, the moldability becomes poor, that is, it becomes crumbly, and the impact resistance, stain resistance, and surface quality deteriorate.

あるので、耐摩耗性、耐擦過性、耐衝撃性等の物
理的性能のみならず、耐汚染性、耐薬品性等の化
学的性能にも優れた成形物を得ることが出来る。[Effects of the Invention] According to the present invention, since the amount of inorganic particles mixed is optimal, not only physical properties such as abrasion resistance, scratch resistance, and impact resistance, but also stain resistance, chemical resistance, etc. Molded products with excellent chemical performance can also be obtained.
また、この発明の成形物は、陶器と相違して高
温により焼成する必要がないので、成形性に優れ
ている。更に無機粒子が多いので、陶器に類似し
た外観の成形を得ることが出来る。 Furthermore, unlike ceramics, the molded product of the present invention does not need to be fired at high temperatures, so it has excellent moldability. Furthermore, since there are many inorganic particles, it is possible to obtain a molded product with an appearance similar to that of ceramics.

樹脂結合剤及び小径無機粒子の混練作業を容易に
して、均一な混合を容易にすることが出来る。 In addition, since the beads have large-diameter inorganic particles with a particle size of 150μ to 1000μ, that is, the total surface area of the large-diameter inorganic particles does not become too large compared to a case where the particle size is less than 150μ, and the large-diameter Since the surface of the inorganic particles is smooth, it is possible to easily knead the large-diameter inorganic particles, the synthetic resin binder, and the small-diameter inorganic particles before molding, thereby facilitating uniform mixing.
