Problems solved by technology

[0006] The disadvantage of the meta-formazan-white system is that it affects the vulcanization speed of the rubber material, which will slow down the vulcanization speed and affect the production efficiency
In order to increase the vulcanization speed, it is necessary to increase the amount of vulcanization system in the rubber compound, or use a more efficient accelerator, resulting in higher costs
In addition, due to the poor thermal stability of the formaldehyde carrier, it is easy to release formaldehyde in advance when heated, so the temperature of the rubber should be reduced as much as possible, and the requirements for tooling are higher

Embodiment 1

[0036] 1. The raw material components of the adhesion promoter are as follows (parts by weight):

[0037] 80.8 parts of liquid butadiene rubber;

[0038] 18 parts of maleic anhydride;

[0039] Initiator DCP 1.2 parts.

[0040] 2. Preparation of adhesion promoter

[0041] (1) Inject liquid butadiene rubber into the reaction kettle, stir and heat to 135±3°C;

[0042] (2) Maleic anhydride is dropped into the reactor, and under stirring condition, it is incubated for 10 ± 1 minute;

[0043] (3) adding initiator DCP;

[0044] (4) Continue to stir and keep warm for 15-20 minutes to obtain the adhesion promoter.

[0045] 3. The application of this adhesion promoter in general-purpose fabric core conveyor belts. The product implements the national standard GB / T7984—2001 "Conveyor belt with rubber or plastic covering layer for general purpose fabric core conveyor belt", in which the requirement for bonding strength is not less than 4.5N / mm, and this application example can reach ...

Embodiment 2

[0051] 1. The raw material components of the adhesion promoter are as follows (parts by weight):

[0052]

[0053] The dispersant is sodium dodecylbenzenesulfonate.

[0054] 2. Preparation of adhesion promoter

[0055] (1) Inject liquid butadiene rubber into the reaction kettle, stir and heat to 135±3°C;

[0056] (2) Maleic anhydride is dropped into the reactor, and under stirring condition, it is incubated for 10 ± 1 minute;

[0057] (3) Add initiator DCP and dispersant;

[0058] (4) Continue to stir and keep warm for 15-20 minutes to obtain the adhesion promoter.

[0059]3. The application of this adhesion promoter in tubular fabric core conveyor belts. The basic requirements of this product are the same as those of Example 1, but because its use environment is much harsher than that of Example 1, it is required to have a bonding strength of more than 13.0 N / mm, which is much higher than the requirements of GB / T7984-2001, and the difficulty is relatively high. This a...

Abstract

The invention discloses an adhesion promoter for rubber as well as a preparation method and application thereof, belonging to the technical field of rubber preparation. The adhesion promoter comprises the following components in parts by weight: 60-85 parts of liquid cis-butadiene rubber, 13-25 parts of maleic anhydride, 1-4 parts of an initiator and 0.1-0.8 part of a dispersant, wherein the sum of the components is 100. The prepared adhesion promoter is applied to a rubber preparation formula, so that a mixing process of rubber materials is simplified, matching requirements of various types of rubber can be widely met, and meanwhile, the adhesive strength between the rubber and fabrics can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of rubber preparation, in particular to the application of an adhesion promoter for rubber. Background technique [0002] The bonding of rubber and fabric has always been a subject of continuous improvement in the rubber industry, especially in the rubber conveyor belt industry, which requires extensive use of fabric as a skeleton material. The general solution is to add a traditional chemical adhesive, i.e., a meso-formic-white adhesive system, to the rubber formula to improve the bonding force between the rubber and the fabric. [0003] The m-formula-white adhesive system refers to the addition of hexamethylenetetramine or hexamethoxymethylmelamine as methylene donor, resorcinol or its derivatives as resorcinol in the rubber formula. Three materials of diphenol donor and white carbon black can improve the bonding strength between rubber and fabric. At this time, it is generally believed that hexamethylen...
