Abstract

The invention discloses the technical field of rubber products and particularly relates to a rubber conveyor belt. The invention aims at providing a rubber conveyor belt which has the advantages of good wear resistance, good heat-conducting effect, good strength and good elongation. The rubber conveyor belt comprises the following components: 100 parts of butadiene-styrene rubber 1500, 5-15 parts of nanometer ZnO, 0.5-3 parts of stearic acid, 0.5-5 parts of an anti-aging agent RD, 0.5-5 parts of protective wax RP-3, 0.5-5 parts of an anti-aging agent 4010NA, 1-15 parts of an anti-aging agent MB, 0.5-65 parts of carbon black N234, 0-3 parts of a dispersant AT-C, 0-15 parts of petroleum resin, 1-10 parts of dioctyl sebacate, 0.5-3 parts of an accelerator CZ, 0.5-3.5 parts of an accelerator DTDM and 0.5-2 parts of an accelerator TMTD. After being used for a long term, the rubber conveyor belt disclosed by the invention is high in wear-resistant strength at both sides and good in heat-conducting property and after being aged, the conveyor belt has better change rate of strength and the change rate of elongation at break.

Description

A kind of rubber conveyer belt

Technical field

The present invention relates to a kind of rubber item technical field; Especially a kind of rubber conveyer belt.

Background technology

In use there is some shortcoming following in rubber conveyer belt common on the market at present: (1) both sides abrasion of conveying belt after long-time use are comparatively serious; (2) thermal conductivity of conveying belt is bad; (3) conveying belt after weathering, and change rate of strength≤-30% of this conveying belt, pulls apart elongation change≤-50%.

For above problem, be badly in need of us and solve.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of rubber conveyer belt that a kind of wear resistance is good, good heat conduction effect, intensity are good and elongation is good is provided.

In order to achieve the above object, a kind of rubber conveyer belt designed by the present invention, it is made up of 100 parts of butadiene-styrene rubbers, 1500,5 ~ 15 parts of nano zine oxides, 0.5 ~ 3 part of stearic acid, 0.5 ~ 5 part of anti-aging agent RD, 0.5 ~ 5 part of protection wax RP-3,0.5 ~ 5 part of antioxidant 4010NA, 1 ~ 15 part of antioxidant MB, 0.5 ~ 65 part of carbon black N234,0 ~ 3 part of dispersant A T-C, 0 ~ 15 part of petroleum resin, 1 ~ 10 part of dioctyl sebacate, 0.5 ~ 3 part of accelerant CZ, 0.5 ~ 3.5 part of vulkacit D TDM and 0.5 ~ 2 part Vulcanization accelerator TMTD.

The preparation technology flow process of this rubber conveyer belt in a mixed technique is as follows:

The first step, adds butadiene-styrene rubber 1500 60 DEG C ~ 80 DEG C time, then 85 DEG C ~ 90 DEG C time, adds nano zine oxide, stearic acid, anti-aging agent RD, protection wax RP-3, antioxidant MB, dispersant A T-C and petroleum resin successively;

Second step, then carbon black N234 and dioctyl sebacate is added 95 DEG C ~ 135 DEG C time;

3rd step, finally adds accelerant CZ, vulkacit D TDM and Vulcanization accelerator TMTD 85 DEG C ~ 105 DEG C time.

A kind of rubber conveyer belt of gained of the present invention, after long-time use, the both sides abrasive wear resistance of conveying belt is high, and the thermal conductivity of conveying belt is good, and conveying belt after weathering, the change rate of strength of this conveying belt and to pull apart elongation change performance better.

Embodiment

A kind of rubber conveyer belt that the present embodiment describes, it is made up of 100 parts of butadiene-styrene rubbers, 1500,6 parts of nano zine oxides, 2. part stearic acid, 1.5 parts of anti-aging agent RDs, 1 part of protection wax RP-3,1 part of antioxidant 4010NA, 1.5 parts of antioxidant MBs, 53 parts of carbon black N234,2 parts of dispersant A T-C, 6 parts of petroleum resin, 2.5 parts of SA dioctyl esters, 2.5 parts of accelerant CZs, 2 parts of vulkacit D TDM and 1 part Vulcanization accelerator TMTDs.

The preparation technology flow process of a kind of rubber conveyer belt of the present invention in a mixed technique is as follows:

The first step, adds butadiene-styrene rubber 1500 70 DEG C time, then 90 DEG C time, adds nano zine oxide, stearic acid, anti-aging agent RD, protection wax RP-3, antioxidant MB, dispersant A T-C and petroleum resin successively;

Second step, then carbon black N234 and dioctyl sebacate is added 110 DEG C time;

3rd step, finally adds accelerant CZ, vulkacit D TDM and Vulcanization accelerator TMTD 100 DEG C time.

The performance index of a kind of rubber conveyer belt of gained of the present invention are as follows:
