Problems solved by technology

From the analysis of the microstructure of the current copolymer materials, the bonding between the two phases is mostly a physical combination, and most of them form sea-island structures instead of interpenetrating polymer networks (IPN), which directly affects the strength properties of the materials and cannot be used as Alternative materials for some metal equipment or metal parts in mining machinery

Embodiment 1

[0012] Embodiment 1: In the open mill that roll temperature is 140 ℃, add raw material successively by weight ratio: polystyrene 70, styrene-butadiene rubber 30, phenolic resin 40, initiator HMT (C 6 h 12 N 4 ) 3, zinc oxide 5, reinforcing agent high wear-resistant carbon black 25, anti-aging agent A 1.5, sulfur 1.5, accelerator DM 0.5, TT 0.7, CZ 1.2. Add the above raw materials one by one and knead them evenly, then remove the sheet, cool and park for 12 hours, then cut the mixture and put it into the vulcanizer for vulcanization and cross-linking reaction. When the vulcanization temperature is 155°C, the time is 25 minutes, and the pressure is 16KNf , the minimum wear of the obtained polymer material is 0.3cm 3 / 1.61km.

[0013] It can also be done using a mixer. In the above process, after adding the reinforcing agent and before adding the active agent zinc oxide, coumarone resin and paraffin wax with a weight ratio of 4 and 2 are added, so that the resulting polymer m...

Abstract

The present invention discloses a polymer material with its preparation method and applications. The said preparation method is: plastics and rubber are orderly melted in rubber refining machine; after being completely mixed, phenolic resin, initiator, reinforcing agent, active-agent zinc oxide, stearic acid, antioxidant A are orderly added; at last, crosslinking agent sulfur, accelerator DM, TT, CZ are added, and are taken out, after being uniformly mixed; Let them cooling for 12 hours, the materials are put into vulcanizer for crosslinking vulcanization. Finally, the polymer material which has high density of chemical crosslinking, good stability, excellent wear resistance, and high strength, is produced. The present invention is simple in process, by which the acquired polymer material can be used in mine machines and equipments or those devices which order excellent wear resistance, high resistance to impact strength, to widely replace metal materials, and has broad application prospect and great popularization value.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a mining polymer material and its manufacturing method and application. Background technique [0002] In the process of screening and crushing ore in the mining industry, mining machinery is directly subjected to wear, impact, and vibration to produce different degrees of fatigue deformation. Compared with other equipment, the maintenance rate is high and the service life is shortened due to material failure. This is not only It consumes a lot of steel, wastes manpower and delays the construction period, resulting in serious economic losses. Therefore, it is an important topic in the research of mining machinery to study a non-metallic material to replace metal parts, achieve the effect of using softness to overcome rigidity, and increase the service life of mechanical parts. [0003] At present, polymer blending has become a very popular technology. As long as two pol...
