Detailed Description
In order that the objects, features and advantages of the invention will be more clearly understood, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the description that follows, but which are intended to be encompassed by the invention in many different forms, all of which are deemed to be within the scope of the invention. Accordingly, the invention is not limited by the specific implementations disclosed below.
Example one
The embodiment provides a chlorosulfonated polyethylene rubber composition which comprises the following raw materials in parts by weight: 60 parts of chlorosulfonated polyethylene rubber; 7.5 parts of butadiene rubber; 15 parts of high styrene; 3 parts of a vulcanizing agent; 19 parts of white carbon black; 30 parts of kaolin; 11 parts of a plasticizer; 1.5 parts of paraffin; 1.8 parts of an accelerator; 9 parts of antimony trioxide; 45 parts of superfine aluminum hydroxide.
The chlorosulfonated polyethylene rubber used in this example had a chlorine content of 30%, which had a significant effect on the properties of the chlorosulfonated polyethylene rubber. The chlorine content used in the invention is 27-33%, so that the chlorosulfonated polyethylene rubber has more excellent processing performance, and the compatibility of the chlorosulfonated polyethylene rubber with the raw materials of a filling system and a vulcanization system during blending is improved, thereby effectively introducing high acid and alkali resistance into the prepared chlorosulfonated polyethylene rubber composition.
The rubber composition has an advantage over natural rubber in that the performance complementation is achieved by blending of various raw materials. The chlorosulfonated polyethylene rubber composition prepared by the embodiment retains the acid and alkali resistance of chlorosulfonated polyethylene rubber, improves the elasticity by adding butadiene rubber, improves the hardness by adding high styrene, enables the rubber composition to obtain more excellent performance than monomer rubber, can be suitable for more use occasions, and meets more strict use requirements.
In the vulcanizing agent of this example, active magnesium oxide having an iodine absorption value of 150 was used to promote vulcanization of chlorosulfonated polyethylene rubber and to sufficiently progress the crosslinking reaction.
The white carbon black and the kaolin are used as reinforcing agents, so that the processability of the rubber composition can be improved, and the mechanical property can be improved.
The white carbon black and hydroxyl groups and other groups on the surface of the kaolin can generate strong absorption with chlorosulfonated polyethylene rubber between molecular interfaces, so that a slidable strong bond is formed, the reactivity of the rubber composition is further reduced, and the acid and alkali resistance of the rubber composition is improved.
The plasticizer of this example uses dioctyl phthalate DOP as an ester plasticizer, and can improve the performance of the rubber composition at low temperature.
The paraffin wax also has a plasticizing effect, but in the embodiment, the paraffin wax plays a protective function more, and can be transferred to the surface of the rubber composition after vulcanization, so that the effect of physically isolating acid and alkali liquor can be achieved.
The accelerator of the embodiment is compounded by using 2, 2' -dibenzothiazyl disulfide DM and dipentamethylenethiuram tetrasulfide DPTT, and the mass ratio is 2: 3, the crosslinking degree of the vulcanization reaction can be improved.
Antimony trioxide and superfine aluminum hydroxide are compounded to serve as a flame retardant, and the antimony trioxide and the superfine aluminum hydroxide have a synergistic effect and can realize halogen-free flame retardance.
