Abstract
The invention discloses heat-resistant chloroprene rubber which is prepared from the following components in parts by mass: 70-80 parts of chloroprene rubber, 5-6 parts of zinc oxide, 0.5-3 parts of dimethylaniline, 10-20 parts of white carbon black, 10-15 parts of ground calcium carbonate, 2-13 parts of dioctyl phthalate, 0.5-1.5 parts of benzothiazolethiol, 3-12 parts of heavy aromatic oil and 2-8 parts of an emulsifier. The heat-resistant chloroprene rubber is characterized in that the heat-resistant chloroprene rubber is good in heat resistance and can be used for some machines under a high temperature condition so as to realize the effects of no aging and deforming for a long time.
Description
Technical field
The present invention relates to a kind of chloroprene rubber, particularly relate to a kind of thermotolerance chloroprene rubber.
Background technology
The kind of rubber is a lot, and rubber is divided into natural rubber and synthetic rubber by raw material.Rubber is divided into again universal and Special type two class by use.
The over-all properties of general purpose rubber is better, and application is comparatively extensive, mainly contains natural rubber, polyisoprene rubber, styrene-butadiene rubber(SBR) and cis-1,4-polybutadiene rubber.Special type rubber refers to the rubber with some property, mainly contains chloroprene rubber, paracril, silicon rubber, viton and thiorubber etc.
Chloroprene rubber has lot of advantages, than if any higher chemical stability, has good water tolerance etc., and its good performance determines its purposes widely, and therefore, chloroprene rubber is widely used in all trades and professions.
Summary of the invention
The present invention relates to a kind of thermotolerance chloroprene rubber, be characterized in that there is good thermotolerance, can effectively prevent high temperature and cause the aging distortion of rubber item.
A kind of thermotolerance chloroprene rubber, it is characterized in that, each component material and mass fraction thereof are: chloroprene rubber 70 ~ 80 parts, 5 ~ 6 parts, zinc oxide, xylidine 0.5 ~ 3 part, white carbon black 10 ~ 20 parts, water-ground limestone 10 ~ 15 parts, dioctyl phthalate (DOP) 2 ~ 13 parts, benzothiazolyl mercaptan 0.5 ~ 1.5 part, high aromatic oil 3 ~ 12 parts, emulsifying agent 2 ~ 8 parts.
A kind of manner of formulation of thermotolerance chloroprene rubber is: by fritter chloroprene rubber raw material and zinc oxide, xylidine, white carbon black, water-ground limestone, dioctyl phthalate (DOP), benzothiazolyl mercaptan, high aromatic oil, emulsifying agent, be placed in colloidal sol still, rotating speed is 60 ~ 80r/min, and dissolving and mix and blend obtain product in 24 ~ 32 hours.
Embodiment
Embodiment 1:
To prepare thermotolerance chloroprene rubber 100g:
Chloroprene rubber 60g, zinc oxide 5g, xylidine 1.5g, white carbon black 15g, water-ground limestone 11g, dioctyl phthalate (DOP) 3g, benzothiazolyl mercaptan 0.8g, high aromatic oil 5g, emulsifying agent 3g.
A kind of manner of formulation of thermotolerance chloroprene rubber is: by fritter chloroprene rubber raw material and zinc oxide, xylidine, white carbon black, water-ground limestone, dioctyl phthalate (DOP), benzothiazolyl mercaptan, high aromatic oil, emulsifying agent, be placed in colloidal sol still, rotating speed is 60 ~ 80r/min, and dissolving and mix and blend obtain product in 24 ~ 32 hours.
In above-described embodiment, apply rational proportioning, and suitable method, the chloroprene rubber obtained has good thermotolerance, the aging and distortion that can effectively prevent Yin Gaowen from causing.
To prepare thermotolerance chloroprene rubber 100g:
Chloroprene rubber 65g, zinc oxide 5.5g, xylidine 2g, white carbon black 12g, water-ground limestone 12.5g, dioctyl phthalate (DOP) 3.5g, benzothiazolyl mercaptan 0.7g, high aromatic oil 6.5g, emulsifying agent 3.5g.
The manner of formulation of thermotolerance chloroprene rubber is identical with embodiment 1.
In above-described embodiment, have changed the mass fraction of each material, make the product thermotolerance that obtains better.
In sum, the present invention has good thermotolerance, may be used for some machinery under hot conditions, reaches long-time not aging, indeformable effect.
Although done detailed description, protection domain has been not limited thereto.
