Oil-resistant flame-retardant covering adhesive and preparation method thereof

Abstract

The invention provides an oil-resistant flame-retardant covering adhesive with good oil resistance and flame-retardant properties and a preparation method thereof. According to the technical scheme, the adhesive comprises the following components in parts by weight: 0-50 parts of butadiene-acrylonitrile rubber, 0-50 parts of butadiene styrene rubber, 25-75 parts of reinforcing fillers, 0.5-5 parts of a vulcanizing agent, 0.2-5 parts of a vulcanizing accelerator, 2-10 parts of a vulcanizing activator, 0.5-2.5 parts of a coupling agent, 5-25 parts of a plasticizer, 1-5 parts of an anti-aging agent and 5-50 parts of a flame retardant. The preparation method comprises the following steps: (1) plastifying; and (2) mixing. The oil-resistant flame-retardant covering adhesive disclosed by the invention has the beneficial effects that the formula adopts proper materials and scientific ratios, and the covering adhesive has high oil resistance and flame-retardant properties. The application range of the conveyor belt is widened, and the safety coefficient and working efficiency of transportation materials are improved.

Description

Technical field:

[0001] The invention relates to the technical field of covering glue, in particular to an oil-resistant and flame-retardant covering glue and a preparation method thereof. Background technique:

[0002] With the development of China's economy, there have been new changes in the parts of the conveyor belt for transporting materials. The oil-resistant conveyor belt has relatively good oil resistance and is suitable for transportation of oily materials and occasions where oily and chemical solvents may appear. The general flame-retardant fabric core flame-retardant conveyor belt is suitable for conveying non-corrosive block, granular and powdery materials in flammable and explosive environments such as wells. In some special environments, the materials conveyed by conveyor belts are oily and have fire hazards. However, at present, oil-resistant conveyor belts and general-purpose fabric-core flame-retardant conveyor belts can only meet the requirements of a sin...
