Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with examples.

[0011] The present invention prepares fatigue-resistant eucommia gum and its combined rubber vulcanizate according to a specific process, and the described eucommia gum and its combined rubber vulcanized rubber include the following components in parts by weight:

[0012] Eucommia gum / combined rubber: 100-10 / 0-90 parts; active agent: 4-8 parts;

[0013] Antiaging agent: 1-4 parts; Vulcanizing agent: 1-6 parts;

[0014] Reinforcing filler: 30-80 parts; vulcanization accelerator: 1-4 parts;

[0015] Softener: 0-10 parts

[0016] The eucommia gum involved in the present invention is a kind of good insulating material with the characteristics of hard quality at room temperature, low melting point, easy processing, etc., and it has good acid resistance, alkali resistance and seawater corrosion resistance. Adding eucommia gum to natural rubber or synthetic rubber can reduce the heat gen...

Abstract

The invention provides natural and fatigue-resistant gutta-percha vulcanized rubber and a preparation method thereof and relates to rubber and a preparation method thereof. The natural and fatigue-resistant gutta-percha vulcanized rubber is prepared from components in parts by weight as follows: 10-100/0-90 parts of the gutta-percha/blend rubber, 4-8 parts of an active agent, 1-4 parts of an anti-aging agent, 30-80 parts of reinforcing filler, 1-6 parts of a vulcanizing agent, 1-4 parts of a vulcanization accelerator, 0-10 parts of a softening agent and other auxiliaries. The preparation method of the fatigue-resistant gutta-percha/blend rubber vulcanized rubber comprises the following technological steps: A, plastication and mixing; B, remilling and vulcanization. The fatigue-resistant gutta-percha/blend rubber vulcanized rubber has reasonable components in the formula and higher anti-fatigue performance. The vulcanized rubber material prepared with the method has good anti-fatigue performance and long service life, can be widely applied to tires, triangular belts, synchronous belts, conveying belts and shock-reducing rubber products and has higher popularization and application value.

Description

technical field [0001] The invention relates to a rubber and a preparation method thereof, in particular to a natural fatigue-resistant Eucommia vulcanized rubber and a preparation method thereof. Background technique [0002] Eucommia rubber, also known internationally as gutta-pereha, is a natural polymer material produced from the Eucommia tree, which is isomers with natural rubber. Eucommia rubber is extracted from Eucommia ulmoides and other plants, and its main component is trans-1,4-polyisoprene (EUG for short), which crystallizes rapidly and presents two crystal forms below 60°C. Crystalline polymer with high hardness and high tensile strength. At present, the rubber composition modified by Eucommia rubber has the advantages of wear resistance, tear resistance, corrosion resistance, and fatigue resistance. It can be used together with natural rubber and synthetic rubber, and is a good material for preparing high-quality rubber products. It is expected that Eucommia...
