preparation example Construction

[0031] The preparation method of acid-resistant clay is as follows: add soybean polysaccharide and sodium fluorosilicate to potassium water glass and mix it, pour it into the mixer, add sodium silicate into the machine, stir for 5 minutes until it is evenly mixed, then add phenolic resin to continue Stir for 5 minutes, and the acid-resistant cement is obtained after the stirring is completed.

[0032] A preparation process for a flame-retardant and burn-resistant rubber conveyor belt, comprising the following steps:

[0033] S1. Add styrene-butadiene rubber to the internal mixer, then press the top bolt for 50 seconds to lift the weight, then add anti-aging agent, coking agent, flame retardant, dispersant and 1 / 2 White Carbon black, press the top bolt for 90 seconds and lift the mound, then add the remaining White Carbon black and press the top plug for 120 seconds, after heating up to 120°C, deglue at a speed of 25rpm to obtain rubber material A;

[0034] S2. Pour the rubber ...

Embodiment

[0038] In the following examples one to three, the same raw materials were used to prepare the cover layer, and the composition of the raw materials in each example is shown in the table below:

[0039]

[0040]

[0041] In each embodiment, the process steps of preparing a kind of flame-retardant and burning-resistant rubber conveyor belt from the above-mentioned raw materials are as follows:

[0042] S1. Add styrene-butadiene rubber to the internal mixer, then press the top bolt for 50 seconds to lift the weight, then add anti-aging agent, coking agent, flame retardant, dispersant and 1 / 2 White Carbon black, press the top bolt for 90 seconds and lift the mound, then add the remaining White Carbon black and press the top plug for 120 seconds, after heating up to 120°C, deglue at a speed of 25rpm to obtain rubber material A;

[0043] S2. Pour the rubber material A in S1 into a mixing kettle, add sodium linoleate aqueous solution, lead acetate aqueous solution and acid-re...

Abstract

The invention relates to the technical field of rubber products, in particular to a flame-retardant burning-resistant rubber conveying belt and a preparation process thereof. The surface of the conveying belt is coated with a covering layer. The covering layer is prepared from the following raw materials in parts by mass: 90 to 110 parts of butadiene styrene rubber, 2 to 6 parts of an anti-aging agent, 50 to 70 parts of white carbon black, 2 to 5 parts of a dispersing agent, 1 to 5 parts of sulfur, 0.5 to 1.5 parts of a vulcanization accelerator, 8 to 10 parts of a flame retardant, 8 to 16 parts of a coking agent, 3 to 5 parts of a sodium linoleate aqueous solution, 0.3 to 0.7 part of a lead acetate aqueous solution and 3 to 7 parts of acid-resistant daub; the preparation process of the conveying belt comprises the following steps: S1, adding the butadiene styrene rubber into an internal mixer, and then adding the anti-aging agent, the coking agent, the dispersing agent and the white carbon black. The flame-retardant burning-resistant conveying belt can improve the flame-retardant burning-resistant capability of the conveying belt and the corrosion resistance of the conveying belt to strong acid, and the corrosion resistance of the conveying belt can be further improved through a protective layer formed by lead soap generated by reaction on the conveying belt.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a flame-retardant and burn-resistant rubber conveyor belt and a preparation process thereof. Background technique [0002] Conveyor belt is the main part of belt conveyor. It is mainly used for large-scale continuous transportation of coal, mining, metallurgy, chemical industry, construction and transportation. The materials to be transported are divided into block, powder, paste and parts. items etc. According to the different raw materials used in the covering layer, the conveyor belt industry can be divided into two categories: heavy-duty conveyor belts and light-duty conveyor belts. The former uses rubber (including natural rubber and synthetic rubber) as the main raw material, so it is also called rubber conveyor belt. Its use The scope is concentrated in the fields of heavy industry and infrastructure construction; the latter mainly uses polymer materials, which ar...
