Title:
【発明の名称】抗菌性軟質ポリウレタンフォームの製造方法
Document Type and Number:
Japanese Patent JP2813693
Kind Code:
B2
Abstract:
The present invention provides a process for producing an antibacterial flexible polyurethane foam containing an antibacterial agent dispersed therein from a foaming mixture composed of polyols, organic isocyanates, catalysts, and blowing agents. The process is characterized in that the antibacterial agent is added to the foaming mixture and the catalyst is an organic amine which is used alone or in combination with a tin compound. In the latter case, the tin compound is a tetravalent tin compound or a divalent tin compound which is used in an amount less than 1 part by weight for 1 part by weight of the antibacterial agent. The antibacterial flexible polyurethane foam retains the antibacterial action for a long time and is safe because it contains an inorganic antibacterial agent dispersed therein which does not yield resistant bacteria.
