Problems solved by technology

As we all know, nitrile rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. It has good oil resistance, good heat resistance and excellent antistatic performance. However, the disadvantage of single nitrile rubber as the main rubber is its low elasticity. Average wear resistance, average strength, small surface friction coefficient

Embodiment 1

[0045] 1) Preparation and mastication of raw rubber

[0046] Plastication of butadiene rubber: weigh butadiene rubber (BR9000), adjust the roller distance of the open rubber mixer to 0.5mm, put the butadiene rubber on the roller, let it fall freely, and add peptizer I (SJ-103). Repeat the thin pass six times and then use it.

[0047] Mastication of natural rubber: Weigh natural rubber (constant viscosity CV60), add peptizer II (SJ-103), and the operation process is the same as above.

[0048] Plastication of nitrile rubber: weigh nitrile rubber (NBR220), add peptizer III (SJ-103), and the operation process is the same as above.

[0049] 2) Mixing of glue

[0050] Carry out mixing according to the raw material proportioning of table 1, specifically comprise the following steps:

[0051] Put the butadiene rubber, natural rubber and nitrile rubber masticated in step 1) into the internal mixer, press down the top bolt, the pressure is 0.8MPa, and banbury for 1.5 minutes, so th...

Embodiment 2-3

[0075] According to the preparation of raw materials in Table 1, the rubber friction layer was prepared according to the same operation as Step 1)-Step 4) of Example 1, and the same performance test was carried out. See Table 2 for the performance test results.

Abstract

The invention discloses a high-wear-resistance rubber friction layer for a folder gluer conveying belt and a preparation method of the rubber friction layer. The friction layer is prepared from raw materials in parts by weight as follows: 60-90 parts of butadiene rubber, 5-20 parts of natural rubber, 5-20 parts of NBR (nitrile butadiene rubber), 40-60 parts of a reinforcing agent, 3-5.5 parts of aprotective agent, 8-12 parts of a vulcanizing agent, 6-9 parts of a vulcanizing aid and 12-16 parts of rubber oil through plastifying, mixing, rolling and vulcanization. Three different types of rubber are combined and can make up defects of one another and play respective advantages, tensile strength, wear resistance and rebound resilience are significantly improved, the surface friction coefficient is increased, and wear resistance is enhanced, so that the overall performance of the folder gluer conveying belt is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a rubber friction layer of a conveyor belt of a folder-gluer with high wear resistance and a preparation method thereof. Background technique [0002] In the packaging and printing industry, the application of the folder-gluer is the last process of packaging box processing. It is to fold the printed and die-cut cardboard into shape and paste it. The machine-glued box replaces the manual box-gluing method, which reduces labor costs. , improving production efficiency. [0003] The main function of the folder-gluer conveyor belt is to transport cardboard, printed books, etc. Whether its operation is smooth or not directly determines the production efficiency of the entire equipment. The structure of the traditional conveyor belt consists of five layers, from top to bottom: upper friction layer, upper connection layer, middle skeleton layer, lower connection la...
