Flaming-retardant and heat-resisting conveyer belt

Abstract

The invention discloses a flaming-retardant and heat-resisting conveyer belt, and relates to the field of conveyer belt manufacturing. The conveyer belt comprises, by mass, 60-100 parts of ethylene-propylene-diene monomer rubber, 60-100 parts of ethylene-propylene-diene monomer regenerated rubber, 30-60 parts of carbon black, 12-15 parts of zinc oxide, 10-20 parts of composite flame retardant, 3-10 parts of high-temperature stabilizers, 1-3 parts of stearic acid, 1-10 parts of phenolic resin BN-1, 1.5-5 parts of accelerant, 1.5-3 parts of vulcanizing agents, 2-5 parts of aluminium hydroxide, 1-3 parts of anti-aging agents and 0.1-0.3 part of sulphur. Combining smelting is carried out on synthetic rubber, the synthetic rubber is mixed with various compounding agents, compound smelting is carried out, compound rubber is prepared, after sheeting, cooling and placing are carried out on the compound rubber, rolling forming is carried out, a belt embryo is formed, and after combing is carried out on the belt embryo, the flaming-retardant and heat-resisting conveyer belt is obtained. The flaming-retardant and heat-resisting conveyer belt is a safe product which has the flaming-retardant and heat-resisting performances, raw materials are easy to obtain and can be bought in the market, the production technology is simple, and the flaming-retardant and heat-resisting conveyer belt is suitable for industrial production.

Description

Technical field [0001] The present invention involves the field of conveyor belt manufacturing, which specifically involves a flame retardant heat -resistant conveyor belt. Background technique [0002] At present, in order to meet the environmental requirements of the on -site use environment in the metallurgy and steel industry, the domestic conveyor belt is basically mainly to improve thermal resistance.It is easy to lead the heat -resistant conveyor that does not have flame retardant performance, which brings great hidden dangers to the lives of the staff at the equipment and work site. [0003] Because in the steelmaking plant, thermal power plant, cement plant and other companies, the materials transported by the transportation machinery are all high -temperature materials. If the metal tracking material is used, it is not only the power consumption, the heat loss is large, but it is easy to cause the damage of the personnel.Convenient, so light weight and good intensity co...

Problems solved by technology

[0002] At present, the conveyor belts used in the metallurgical and iron and steel industries are mainly used to meet the environmental requirements of the site. The domestically produced conveyor belts are basically designed to improve heat resistance. However, in many on-site environments, high-temperature materials often have open flames. It is easy to ignite the heat-resistant transport that does not have flame-retardant properties, which will bring great hidden dangers to the lives of equipment and personnel at the work site

[0003] Because in steel mills, thermal power plants, cement plants and other enterprises, the materials transported by the conveying machinery are all high-temperature materials, if metal crawlers are used to transport materials, not only the power consumption is large, the heat loss is large, and it is easy to cause personal injury, it is very difficult to operate. Convenience, so the conveyor belt with light weight and good strength is more and more favored by the industry

, the heat resistance of the conveyor belt is generally not good, the main reason is that the skeleton material can not withstand high temperature, and the temperature and heat resistance of the rubber surface itself is poor, and the rubber surface of the conveyor belt will form expensive cracks due to carbonization and sintering under high temperature environment , due to the large gaps formed by cracks, the heat of high-temperature materials is easily and quickly transferred to the skeleton layer with core, thereby reducing the life of the conveyor belt

The Chinese patent No. 02261969.0 discloses a conveyor belt. The conveyor belt is modified by adding a layer of heat insulation and asbestos between the covering glue and the skeleton to prevent high temperature from passing to the canvas skeleton, but its temperature resistance is only 200 degrees Celsius. Left and right, throwing can not meet the industry's requirements for high temperature resistance of conveyor belts
