Molding material for a household plumbing equipment and a household plumbing equipment fabricated using the same

Abstract

Providing: a molding material for a household plumbing equipment which has superior surface hardness as well as superior water resistance for use in the household plumbing equipment inherent from a polymethyl methacrylate resin, and yet has improved solvent resistance; and a household plumbing equipment fabricated using the molding material. The molding material for a household plumbing equipment is characterized by containing a thermoplastic resin comprising the polymethyl methacrylate resin and a polytrimethylene terephthalate resin in a mass ratio of 90:10-50:50.

Description

TECHNICAL FIELD[0001]This invention relates to a molding material for a household plumbing equipment containing a thermoplastic resin and a household plumbing equipment fabricated using the molding material.BACKGROUND ART[0002]Conventionally, some of thermoplastic resins such as a polypropylene resin (PP), a polybutylene terephthalate resin (PBT), and a polymethyl methacrylate resin (PMMA) have been used for fabricating household plumbing equipments such as a toilet, a hand wash basin, or a face wash basin.[0003]The thermoplastic resin has superior shape forming characteristics and has a cost advantage. However, the thermoplastic resins have disadvantages as well as advantages in physical property. Therefore, the thermoplastic resin has not been used often for fabricating the household plumbing equipment exemplified above. Also, the thermoplastic resins is limited of its intended use depending on the characteristics thereof.[0004]As an example, the polypropylene resin has superior c...

AI Technical Summary

Benefits of technology

[0019]The above described first invention can assure superior surface hardness as well as superior water resistance inherent from the polymethyl methacrylate resin for use in the household plumbing equipment, and yet provide sufficient solvent resistance resulting from the combination of the polytrimethylene terephthalate resin to the polymethyl methacrylate resin to the household plumbing equipment.

[0020]The above described second invention is allowed to have sufficient surface hardness as well as sufficient water resistance for use in the household plumbing equipment, and yet have sufficient solvent resistance for the household plumbing equipment resulting from the combination of the polytrimethylene terephthalate resin to the polymethyl methacrylate resin.

Problems solved by technology

However, the thermoplastic resins have disadvantages as well as advantages in physical property.

Therefore, the thermoplastic resin has not been used often for fabricating the household plumbing equipment exemplified above.

Also, the thermoplastic resins is limited of its intended use depending on the characteristics thereof.

The polybutylene terephthalate resin has superior chemical resistance and superior solvent resistance, but has low surface hardness and inferior durability of water-resistance.

However, it has inferior solvent resistance.

However, this molding material is not suitable, in aspect of the physical property, for fabricating the above-exemplified household plumbing equipments, considering that it is composed mainly of the poly trimethylene terephthalate resin and considering the characteristics of combined material with the various addition ingredients.
