Abstract
The invention relates to the technical field of rubber V belt manufacturing, in particular to a composition for manufacturing cold-resistant rubber V belts. The composition is prepared from, by weight, 60 parts of cis-butadiene rubber, 40 parts of styrene butadiene rubber, 5 parts of zinc oxide, 2 parts of stearic acid, 30 parts of a reinforcing agent, 3 parts of an anti-aging agent, 3 parts of peroxide, 50 parts of a filler and 8 parts of a plasticizer. The composition is simple in structure and good in practicability.
Description
Technical field
The present invention relates to the manufacturing technology field of V-shaped rubber belt, a kind of formula manufacturing arctic rubber V band.
Background technology
Traditional V-shaped rubber belt is during extremely frigid zones uses, owing to strand spacing declines, the internal resistance of strand increases, and strand internal friction increases, and relaxation drastically slows down, elasticity significantly reduces, the ability to work causing rubber declines, such as Chinese invention patent: the one of Application No. 201310753450.3 resists cold natural rubber formulations, by weight, composed of the following components: natural rubber 100 parts, the rubber diaphragm that this cold-resistant formula makes has good pneumatic susceptiveness.Meet railway wagon brake valve rubber in actual use and seal the low temperature requirements of lamina membranacea, the problem solving rubber diaphragm winter low temperature poor sensitivity.But, in actual application process, General Purpose Rubber V band poor-performing (bearing capacity, service life etc.) during extremely frigid zones uses, because the V-shaped rubber belt utilizing single rubber components to form should meet V band performance, meet cold-resistant requirement again, do not reach often, thus, attend to one thing and lose sight of another.
Such as Chinese invention patent: the one of Application No. 201310753450.3 resists cold natural rubber formulations, by weight, composed of the following components: vulcanizing agent 3～5 parts, the rubber diaphragm that this cold-resistant formula makes has good pneumatic susceptiveness.Meet railway wagon brake valve rubber in actual use and seal the low temperature requirements of lamina membranacea, the problem solving rubber diaphragm winter low temperature poor sensitivity.But, the rubber elastomer making the mode of rubber molecule interchain crosslinking (non-carbon-carbon bond) obtain as vulcanizing agent with sulfur is polysulfide bond, and its bond energy is relatively low, is easily broken off (the most aging), and service life is the longest.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide a kind of formula manufacturing arctic rubber V band.
For achieving the above object, the technical scheme is that a kind of formula manufacturing arctic rubber V band, by weight, composed of the following components:
Cis-butadiene cement 60 parts；
Butadiene-styrene rubber 40 parts；
Zinc oxide 5 parts；
Stearic acid 2 parts；
Reinforcing agent 30 parts；
3 parts of age resistor；
Peroxide 3 parts；
Filler 50 parts；
Plasticizer 8 parts.
Further, described peroxide is crosslink agent DCP.
Further, described filler is calcium carbonate.
Further, described age resistor is 4010NA.
Further, described plasticizer is aromatic naphtha.
Further, described reinforcing agent is white carbon black.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the present invention provides is brought: 1. utilize the blended rubber elastomer of 60 parts of cis-butadiene cements and 40 parts of butadiene-styrene rubbers, the cold tolerance of cis-butadiene cement is high (because not having side base on strand, during molecular chain movement, resistance is little, internal friction is little, vitrification point is-105 DEG C), and the performance that butadiene-styrene rubber can make V-shaped rubber belt improves, therefore, select the high rubber elastomer made with high-performance rubber paralled system of cold tolerance can meet V band performance, can meet again cold-resistant requirement, both take into account.2. utilizing crosslink agent DCP rubber each molecule interchain during sulfuration to form carbon-carbon bond (bond energy is high), structure is more stable.3. plasticizer is aromatic naphtha, can significantly reduce brittle temperature and the vitrification point of vulcanization of rubber glue, improves the performance (aspect such as bearing capacity, elasticity) of V-shaped rubber belt.
Detailed description of the invention
A kind of formula manufacturing arctic rubber V band, by weight, composed of the following components:
Cis-butadiene cement 60 parts；
Butadiene-styrene rubber 40 parts；
Zinc oxide 5 parts；
Stearic acid 2 parts；
Reinforcing agent 30 parts；
3 parts of age resistor；
Peroxide 3 parts；
Filler 50 parts；
Plasticizer 8 parts.
Utilize 60 parts of cis-butadiene cements and 40 parts of butadiene-styrene rubbers the blended rubber elastomer with making, the cold tolerance of cis-butadiene cement is high (vitrification point is-105 DEG C), and the performance that butadiene-styrene rubber can make V-shaped rubber belt improves, therefore, the blended rubber elastomer selecting the high formula with high-performance rubber paralled system of cold tolerance to make can meet V band performance, can meet again cold-resistant requirement, both take into account.
Further, described peroxide is crosslink agent DCP, utilizes crosslink agent DCP rubber each molecule interchain during sulfuration to form carbon-carbon bond, and structure is more stable.
Further, described filler is calcium carbonate, in the case of ensureing V-shaped rubber belt performance, reduces cost.
Further, described age resistor is 4010NA, prevents V-shaped rubber belt aging, extends the service life of V-shaped rubber belt.
Further, described plasticizer is aromatic naphtha, can significantly reduce brittle temperature and the vitrification point of vulcanization of rubber glue, improves the performance (aspect such as bearing capacity, elasticity) of V-shaped rubber belt.
Further, described reinforcing agent is white carbon black.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, those skilled in the art carries out common variations and alternatives in the range of technical solution of the present invention and should comprise within the scope of the present invention.
