Embodiment 1

[0010] The present invention relates to a butadiene rubber. Contains the following components: 30 parts of cis-polybutadiene mixture, 5 parts of cyclohexane, 1 part of cobalt oxide, 2 parts of zinc oxide, 3 parts of sulfur, 3 parts of stearic acid, 5 parts of nickel naphthenate, triiso 9 parts of butyl aluminum, 4 parts of boron trifluoride ether, 2 parts of heptane, 8 parts of hydrogen gasoline, 19 parts of accelerator NS, 13 parts of HAF, 15 parts of ASTM type 103 oil, 8 parts of aluminum oxide clinker, 5 parts of cresol. The cis-polybutadiene mixture is formed by mixing cis-1,4-polybutadiene and cis-1,3-polybutadiene. The weight ratio of cis-1,4-polybutadiene and cis-1,3-polybutadiene to the total mixture is 2:5.

Embodiment 2

[0012] The present invention relates to a butadiene rubber. Contains the following components: 50 parts of cis-polybutadiene mixture, 9 parts of cyclohexane, 3 parts of cobalt oxide, 2 parts of zinc oxide, 5 parts of sulfur, 2 parts of stearic acid, 4 parts of nickel naphthenate, triiso 6 parts of butyl aluminum, 4 parts of boron trifluoride ether, 5 parts of heptane, 7 parts of hydrogen gasoline, 19 parts of accelerator NS, 13 parts of HAF, 15 parts of ASTM type 103 oil, 6 parts of aluminum oxide clinker, and 5 parts of cresol. The cis-polybutadiene mixture is formed by mixing cis-1,4-polybutadiene and cis-1,3-polybutadiene. The weight ratio of cis-1,4-polybutadiene and cis-1,3-polybutadiene to the total mixture is 2:5.

Abstract

The invention relates to a butadiene rubber including following components: 30-50 parts of a cis-polybutadiene mixture, 5-9 parts of cyclohexane, 1-3 parts of cobalt oxide, 2-5 parts of zinc oxide, 3-7 parts of sulfur, 1-3 parts of stearic acid, 1-5 parts of nickel naphthenate, 5-9 parts of triisobutyl aluminium, 2-4 parts of boron trifluoride diethyl etherate, 2-6 parts of heptane, 3-8 parts of hydrogenated gasoline, 15-19 parts of an accelerant NS, 10-13 parts of HAF, 11-15 parts of ASTM-typed 103 oil, 2-8 parts of an aluminum oxygen clinker and 2-5 parts of chloroxylenol. The cis-polybutadiene mixture consists of cis-1,4-polybutadiene and cis-1,3-polybutadiene, wherein a weight ratio of the cis-1,4-polybutadiene to the cis-1,3-polybutadiene is 2:5 in the mixture. The butadiene rubber contains the cis-polybutadiene mixture so that the butadiene rubber is effectively reduced in tear strength, is enhanced in anti-slippery performance and adhesive property, and is low in heat-generating property.

Description

technical field [0001] The invention belongs to the field of chemical materials and relates to butadiene rubber. Background technique [0002] In the prior art, butadiene rubber is especially suitable for making automobile tires and cold-resistant products, and can also be used to make cushioning materials and various rubber shoes, adhesive plasters, tapes and sponge rubber. Butadiene rubber has disadvantages such as poor processing performance and raw rubber has a certain cold flow tendency. The emergence of oil-extended butadiene rubber can improve the above shortcomings to a certain extent. However, its tear strength is low, its wet skid resistance is not good, and its adhesion is not as good as that of natural rubber and styrene-butadiene rubber, so it needs to be studied and improved. Therefore, it is urgent to propose a butadiene rubber formulation with better wet skid resistance and adhesion. Contents of the invention [0003] The technical problem to be ...
