Abstract
Belting for use in a conveyor. The belting includes a fabric base and an environmentally friendly rubber composition. The environmentally friendly rubber composition is applied to at least one surface of the fabric base. The environmentally friendly rubber composition includes a rubber component, a filler, a processing oil and a vulcanizing agent. The filler is provided at a concentration of between about 50 and 150 parts per hundred weight of the rubber component. The processing oil is substantially devoid of aromatic oil. The processing oil is provided at a concentration of between about 20 and 60 parts per hundred weight of the rubber component. The vulcanizing agent is provided at a concentration of between about 1 and 10 parts per hundred weight of the rubber component.
Claims21
Belting for use in a conveyor, wherein the belting comprises:
- a fabric base;
- and
- an environmentally friendly rubber composition applied to at least one surface of the fabric base, wherein the environmentally friendly rubber composition comprises:
- a rubber component;
- a filler provided at a concentration of between about 50 and 150 parts per hundred weight of the rubber component;
- a processing oil that is substantially devoid of aromatic oil, wherein the processing oil comprises soybean oil, wherein the processing oil is provided at a concentration of between about 30 and 60 parts per hundred weight of the rubber component;
- and
- a vulcanizing agent provided at a concentration of between about 1 and 10 parts per hundred weight of the rubber component, wherein the environmentally friendly rubber composition exhibits a tensile strength of between about 2,000 psi and about 2,500 psi, an elongation of between about 500% and about 600% and a Din abrasion of less than about 250 mm3.
An environmentally friendly rubber composition comprising:
- a rubber component;
- a filler provided at a concentration of between about 50 and 150 parts per hundred weight of the rubber component;
- a processing oil that is substantially devoid of aromatic oil, wherein the processing oil comprises soybean oil, wherein the processing oil is provided at a concentration of between about 30 and 60 parts per hundred weight of the rubber component;
- and
- a vulcanizing agent provided at a concentration of between about 1 and 10 parts per hundred weight of the rubber component, wherein the environmentally friendly rubber composition exhibits a tensile strength of between about 2,000 psi and about 2,500 psi, an elongation of between about 500% and about 600% and a Din abrasion of less than about 250 mm3.
A method of belting for use in a conveyor, wherein the method comprises:
- preparing an environmentally friendly rubber composition comprising a rubber component, a filler, a processing oil and a vulcanizing agent, wherein the filler is provided at a concentration of between about 50 and 150 parts per hundred weight of the rubber component, wherein the processing oil is substantially devoid of aromatic oil, wherein the processing oil comprises soybean oil, wherein the processing oil is provided at a concentration of between about 30 and 60 parts per hundred weight of the rubber component and wherein the vulcanizing agent is provided at a concentration of between about 1 and 10 parts per hundred weight of the rubber component, wherein the environmentally friendly rubber composition exhibits a tensile strength of between about 2,000 psi and about 2,500 psi, an elongation of between about 500% and about 600% and a Din abrasion of less than about 250 mm3;
- coating the rubber composition on a fabric base to form a coated belt;
- and
- vulcanizing the coated belt to form the conveyor.
