Abstract
The invention discloses a low temperature resistant high-toughness rubber material, comprising the following components in parts by weight: 30-50 parts of natural rubber, 20-40 parts of butadiene rubber, 15-30 parts of silicon rubber, 15-30 parts of ethylene propylene rubber, 10-15 parts of calcium carbonate, 5-10 parts of carbon black, 3-8 parts of zinc oxide, 1-5 parts of a flexibilizer, 1-3 parts of an antioxidant, 0.5-2 parts of anti-ageing agent and 0.1-1 part of a cross-linking agent. The rubber material disclosed by the invention has excellent cold resistance, and is suitable for a low-temperature environment; and meanwhile, the rubber is high in tensile strength, good in toughness, excellent in physical and mechanical properties, long in service life in comparison with similar rubber in the low-temperature environment, and good in oil resistance.
Description
Technical field
The present invention relates to a kind of macromolecular material, be specially a kind of elastomeric material of low-temperature-resistance high-toughness.
Background technology
Rubber, has the strong flexible polymer material of reversible deformation.At room temperature high resilience, can produce comparatively large deformation under very little External Force Acting, resilient after removing external force.Rubber belongs to complete amorphous polymer, and its second-order transition temperature is low, and molecular weight is often very large, is greater than hundreds of thousands of.The molecular chain of rubber can be cross-linked, when rubber after crosslinked deforms by External Force Acting, there is the ability of restoring rapidly, and there are good physical and mechanical property and chemical stability, rubber is the basic raw material of rubber industry, is widely used in and manufactures tire, sebific duct, adhesive tape, cable and other various rubber item.
The winter hardiness of rubber, under the low temperature of regulation, namely keep the ability of its elasticity and normal work, the winter hardiness of rubber depends primarily on two fundamental characteristics of superpolymer, glass transition and crystallization, and rubber both can be made to lose elasticity at low temperatures.The motor capacity that the winter hardiness of rubber is mainly reflected in molecular chain is comparatively strong, relative easy of intermolecular motion, relative low of the energy of cohere.Rubber after sulfuration all has elasticity in the temperature province that near room temperature is very large, and along with the decline of temperature, the pedesis of particulate weakens, and rubber can present hide-like because of the increase of internal viscosity.The pedesis reducing particulate when temperature further stops completely, and rubber will produce freezeout, has both entered brittle glassy region.The crystalline polamer of Here it is crystallinity rubber.This phenomenon shows: by by rubber as at suitable temperature, a part in the irregular molecular structure of rubber inside will there will be and rearrange, its result causes modulus to increase, and tension set expands, and the elasticity of prolongation rubber in time is also slowly lost.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of tensile strength high, and low temperature performance excellent, the elastomeric material of the low-temperature-resistance high-toughness that rebound performance is strong.
The present invention is achieved through the following technical solutions:
