Abstract

The adhesive for brake block of oil field drilling machine consists of adhesive, curing agent, promoter, friction performance regulator, activator, assistant and solvent. The adhesive is linear phenolic resin and acrylonitrile-butadiene rubber, the curing agent is sulfur and hexamethine tetramine, the promoter is cyclohexyl-benzothiazole sulfenamide, the friction performance regulator is carbon black and stannous chloride, the assistant is barium sulfate and the solvent is mixed solvent. The adhesive is suitable for brake block of oil field drilling machine and may be also used in brake blockfor train, automobile, etc.

Description

Technical field: [0001] The invention describes an adhesive used for brake pads of an oil field drilling rig. Specifically, the present invention describes an adhesive suitable for brake pads of oilfield drilling rigs, brake pads of workover rigs, and brake pads of trains and automobiles. Background technique: [0002] The adhesive for brake pads of oilfield drilling rigs is a special adhesive, which uses adhesives to evenly distribute the friction modifier and its fillers in the metal-glass fiber base or metal-asbestos base or other material brake pad matrix, and is produced through a specific process. Into the brake pads, so as to play the role of transmitting power or stopping motion. There are many types of brake pads currently used for oil field drilling rigs, but the disadvantages are low friction coefficient, poor braking stability and wear resistance. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art...
