Embodiment Construction

[0033] The present invention will be further explained below with examples, but the scope of the present invention is not limited to these examples, of course.

[0034] sample preparation

[0035] According to the formula shown in Table 1, with a 1.6 liter Banbury mixer, rubber, carbon black, and other compounds except sulfur, methylene donor and vulcanization accelerator were mixed for 6 minutes to obtain a masterbatch, and then A vulcanization accelerator, a methylene donor, and sulfur were mixed in a master batch using an open rubber mill to obtain rubber compositions, and each rubber composition thus obtained was vulcanized at a temperature of 150° C. for 30 minutes to obtain vulcanized rubber.

[0036] Anti-reversion performance

[0037] In accordance with GB / T 16584-1996, the test method for measuring vulcanization characteristics with a rotorless vulcanizer, measure the vulcanization reversion rate at 150°C for 60 minutes, and the anti-vulcanization reversion rate is ex...

Abstract

The invention provides a rubber composition applied to tire bead fillers. The rubber composition has the characteristics of high elongation at break, high breaking strength and prominent cure reversion resistance. The rubber composition comprises the following components in parts by mass: 100 parts of rubber components, 50-100 parts of carbon black, 3-25 parts of phenolic resin and a methylene donor, wherein each 100 parts of the phenolic resin needs 1-20 parts of the methylene donor. Besides, the invention further relates to a pneumatic tire prepared from the tire bead fillers prepared from the rubber composition.

Description

technical field [0001] The present invention relates to a rubber composition, in particular to a rubber composition and a pneumatic tire using the rubber composition. Background technique [0002] Rubber is a chain-like polymer material, adding a vulcanizing agent can produce a cross-linking reaction with it, forming a three-dimensional network structure, making the rubber change from a plastic material to an elastic material, making the rubber highly elastic and flexible in a wide temperature range. Low plasticity and high strength, but low hardness of vulcanized rubber. It is well known that tires and rubber products require vulcanized rubber with higher hardness. There are many methods for improving and increasing the hardness and modulus of vulcanized rubber, such as increasing the amount of vulcanizing agent or active agent, and adding phenolic resin. The method of increasing the amount of vulcanizing agent can easily cause the amount of sulfur and other vulcanizing ag...
