Abstract

The invention discloses a cold-resistant natural rubber compound. The cold-resistant natural rubber compound is characterized by comprising the following components in parts by weight: 100 parts of natural rubber, 5-10 parts of zinc oxide, 1-2 parts of stearic acid, 20-40 parts of carbon black, 10-20 parts of cold-resistant plasticizer, 3.5-5 parts of anti-aging agent and 3-5 parts of vulcanizing agent. Compared with the prior art, the cold-resistant natural rubber compound has the advantages that the -50 DEG C low temperature test proves that a rubber diaphragm plate manufactured by using the cold-resistant natural rubber compound has good pneumatic sensitivity. In the practical use, the cold-resistant natural rubber compound meets the low temperature requirements of rubber sealing diaphragm plates of brake valves of railway freight cars and solves the problem of poor low temperature sensitivity in winter of the rubber diaphragm plate.

Description

A kind of cold-resistant natural rubber formulations
Technical field
The present invention relates to a kind of cold-resistant natural rubber formulations, belong to chemical technology field.
Background technology
At present, the rubber diaphragm of rail freight air brake valve, in transportation, because China's the North and South span is comparatively large, in the winter time under low temperature condition, traditional rubber diaphragm can become stiff, sensitivity is poor, can not meet the low temperature requirements of railway wagon brake valve rubber sealing lamina membranacea.
Summary of the invention
The present invention is to solve above-mentioned deficiency, provides a kind of cold-resistant natural rubber formulations, and solve conventional rubber lamina membranacea elasticity variation at low temperatures, lamina membranacea becomes stiff, the problem that sensitivity is poor.
Above-mentioned purpose of the present invention is realized by following technical scheme: a kind of cold-resistant natural rubber formulations, is characterized in that: by weight, composed of the following components:
Natural rubber 100 parts;
5 ~ 10 parts, zinc oxide;
Stearic acid 1 ~ 2 part;
Carbon black 20 ~ 40 parts;
Cold resistant plasticizer 10 ~ 20 parts;
3.5 ~ 5 parts, anti-aging agent;
Vulcanizing agent 3 ~ 5 parts.
Cold-resistant natural rubber tensile strength of the present invention: 20 ~ 30MPa; Tensile yield: 500 ~ 800%; Hardness: 40 ~ 50Shore A; Low temperature brittleness :-55 DEG C ~-60 DEG C, the cold-resistant coefficient (-50 DEG C) of compression: 0.6 ~ 0.7.
The present invention's advantage is compared with prior art: the present invention, through-50 DEG C of low-temperature tests, has good pneumatic susceptibility with the rubber diaphragm that this cold-resistant formula makes.Meet the low temperature requirements of railway wagon brake valve rubber sealing lamina membranacea in actual use, solve the problem of rubber diaphragm winter low temperature poor sensitivity.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
A kind of cold-resistant natural rubber formulations, is characterized in that: by weight, composed of the following components:
Natural rubber 100 parts;
5 ~ 10 parts, zinc oxide;
Stearic acid 1 ~ 2 part;
Carbon black 20 ~ 40 parts;
Cold resistant plasticizer 10 ~ 20 parts;
3.5 ~ 5 parts, anti-aging agent;
Vulcanizing agent 3 ~ 5 parts.
Cold-resistant natural rubber tensile strength of the present invention: 20 ~ 30MPa; Tensile yield: 500 ~ 800%; Hardness: 40 ~ 50Shore A; Low temperature brittleness :-55 DEG C ~-60 DEG C, the cold-resistant coefficient (-50 DEG C) of compression: 0.6 ~ 0.7.
With the truck air brake valve lamina membranacea that this natural gum formula manufactures, low temperature elasticity is good, sealing and sensitivity excellence is used at low temperature, lamina membranacea have passed the Low temperature property requirements at cryogenic freezing station, Qiqihar, solve lamina membranacea low temperature elasticity in actual use well poor, brake and alleviate insensitive problem.
It is last it is noted that above-described embodiment is only for example of the present invention is clearly described; and the restriction not to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all embodiments; and thus the apparent change of amplifying out or variation, be still among protection scope of the present invention.
