Embodiment 1

[0035] Such as figure 1 , figure 2 with image 3 As shown, a flat belt with super high temperature resistance includes a bottom surface, an intermediate reinforcement layer and a main body covering layer, and the flat belt also includes a first buffer rubber 2 and a second buffer rubber 4 processed by fluororubber, and the bottom surface is fluororubber rubber Aramid fiber cloth 1 treated with pulp, the middle reinforcing layer is an aramid fiber thread layer 3 composed of aramid fiber threads treated with fluororubber glue, and the subject covering layer 5 is fluororubber;

[0036] The aramid fiber cloth 1 is coated with the first buffer glue 2 on one side, and then the aramid fiber thread is wound on the first buffer glue 2 to form an aramid fiber thread layer 3, and then the aramid fiber A layer of second buffer glue 4 is coated on the line layer 3, and finally the main body covering layer 5 is coated on the second buffer glue 4 to obtain a plane belt skeleton, and the p...

Embodiment 2

[0051] A super high temperature resistant flat belt, including a bottom surface, an intermediate reinforcement layer and a main body covering layer, the flat belt also includes a first buffer rubber 2 and a second buffer rubber 4 processed by fluororubber, and the bottom surface is processed by fluororubber glue Aramid fiber cloth 1, the middle reinforcement layer is an aramid fiber line layer 3 composed of aramid fiber lines treated with fluororubber glue, and the subject covering layer 5 is fluororubber;

[0052] The aramid fiber cloth 1 is coated with the first buffer glue 2 on one side, and then the aramid fiber thread is wound on the first buffer glue 2 to form an aramid fiber thread layer 3, and then the aramid fiber A layer of second buffer glue 4 is coated on the line layer 3, and finally the main body covering layer 5 is coated on the second buffer glue 4 to obtain a plane belt skeleton, and the plane belt skeleton is trimmed and then placed in a hot The vulcanizing m...

Embodiment 3

[0067] The ultra-high temperature resistant flat belt of this embodiment is basically the same as that of Embodiment 1, the main difference being that the angle range between the first aramid fiber line 301 and the second aramid fiber line 302 is 45 degrees, The included angle formed by the first aramid fiber line 301 and the third aramid fiber line 303 is 135 degrees.

[0068] The steps of the thermal vulcanization overlapping operation are as follows: firstly carry out the first-stage vulcanization at a temperature of 165° C. and a pressure of 10 MPa for 15 minutes, and then gradually raise the temperature to 230° C. for a second-stage vulcanization for 24 hours.

[0069] The aramid fiber cloth 1 processed by the fluororubber glue, in its specific processing method:

[0070] Preparation of S1 fluororubber mortar: Weigh 100 parts by weight of fluororubber and add it to an open mill with a roll distance of 0.4mm for 9 times of plasticizing; add the plasticized fluororubber to ...

Abstract

The invention discloses a flat belt with super high temperature resistance, which comprises a bottom surface, a middle reinforcement layer, a main body covering layer and a fluorine rubber processing buffer rubber, the bottom surface is aramid fiber cloth treated with fluorine rubber glue, and the middle reinforcement layer It is an aramid fiber thread layer composed of aramid fiber threads treated with fluororubber glue, and the subject covering layer is fluororubber; the first buffer rubber is coated on one side of the aramid fiber cloth, and then the aramid fiber The thread is wound on the first buffer glue to form an aramid fiber thread layer, followed by coating the second buffer glue on the aramid fiber thread layer, and finally coating the main body cover on the second buffer glue layer, to obtain a plane belt skeleton, trim the plane belt skeleton and place it in a hot vulcanizer for thermal vulcanization lap joint operation, after vulcanization, cool and stand still to obtain the super high temperature resistant plane belt. The super high temperature resistant flat belt of the present invention meets the specific industrial use occasions where the normal use temperature is 200-220°C and high wear resistance is required.

Description

technical field [0001] The invention relates to the technical field of belt transmission, in particular to a super high temperature resistant flat belt. Background technique [0002] The traditional heat-resistant conveyor belt is made of multi-layer rubber cotton canvas (polyester cotton cloth) or polyester canvas covered with high-temperature resistant or heat-resistant rubber, bonded together by high-temperature vulcanization, which mainly includes the bottom surface of the canvas, the middle reinforcement layer and the main body cover Glue is mainly used in metallurgy, construction and other industries to transport sinter, coke, cement clinker and other high-temperature materials. The temperature of the materials is often at 200-500 ° C, sometimes even above 800 ° C, coupled with severe wear, impact and The driving effect requires a high-temperature-resistant conveyor belt that is compatible with it. [0003] The intermediate reinforcing layer of the prior art generally...
