Problems solved by technology

However, there is a problem in the durability of the effect against abrasion
Furthermore, the coating containing Si-H-containing siloxane and a tin catalyst as a specific example has problems in terms of environment and toxicity because it contains a tin compound.
[0004] In addition, although the present inventors proposed a water-repellent gravel treated with Si-H-containing siloxane and a platinum catalyst (Patent No. 3804759: Patent Document 3), the understanding of electrical resistance and wear resistance is not yet known. incomplete

Abstract

Electric resistance stone materials and a method for manufacturing the same are provided to reduce a step voltage and a contact voltage and to maintain high electric resistance for a long period of time by securing water repellent characteristic and non-repairing characteristic based on a silicon water repellent layer. A method for manufacturing electric resistance stone materials(1) includes the following: A composition containing (A) components and (B) components is prepared. The composition is attached to the surface of dry natural stone(2) of 5-50mm diameters. A heat treating process is implemented at a temperature between 50 and 250 degrees Celsius. The (A) components are organopolysiloxane containing at least three Si-H bonds in one molecule, and the (B) components are platinum catalysts.

Description

technical field [0001] The invention relates to a resistance stone which maintains a high resistance value for a long time and a manufacturing method thereof. Background technique [0002] In maintenance, inspection, and management of electric power, communications, and railways, etc., it is necessary to ensure a safe working environment that protects operators from electric shocks, etc. Moreover, as a method for this, it is considered to use special work clothing to protect the body from lightning for outdoor activities such as anti-electric clothing (Japanese Patent Application Laid-Open No. 6-235102; Patent Document 1). To prevent electric shock, etc. [0003] However, in the vicinity of facilities such as electric power, communication, and railways, in order to ensure safety when abnormal voltages are generated, ground current may flow into the ground, and operators working around the facilities may be exposed to step voltage or contact Voltage. In addition, the so-ca...
