Rubber and ceramic composite material and preparation method thereof

Abstract

The invention provides a rubber and ceramic composite material and a preparation method thereof. The rubber and ceramic composite material is prepared from the following components in percentage by weight: 50 percent to 55 percent of natural rubber and 50 percent to 45 percent of nano powder; the total mass is 100 percent. The nano powder is prepared from the following components in parts by weight: 40 to 45 parts of nano silicon dioxide, 35 to 40 parts of nano aluminum sesquioxide, 1 to 1.5 parts of nano molybdenum dioxide, 0.8 to 1 part of nano graphene, 1.5 to 2 parts of a silane coupling agent and 10 to 10.5 parts of an auxiliary material. According to the composite material provided by the invention, four types of dispersed nanoparticles are uniformly embedded into a rubber macromolecular grid to form a grid core and are mutually matched, so that the wearing resistance and anti-ageing performance of the composite material are effectively improved and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of nano-polymer materials, and in particular relates to a ceramic rubber composite material for improving the abrasion resistance of roller rubber and a preparation method thereof. Background technique [0002] The pulley lagging and wear-resistant composite rubber materials commonly used in the market include thermal vulcanization lagging, cold lagging, polyurethane lagging, and ceramic block lagging. The hot-vulcanized lagging was applied relatively early, and the advantage is that the cost is low. The traditional hot-vulcanized lagging has the strongest adhesive force at present, so hot-vulcanized lagging is the mainstream choice for small and medium-sized conveying machinery at present. . However, due to the low vulcanization pressure and high sulfur content of the hot-vulcanized lagging roller, coupled with the low rubber content of the lagging panel, the rubber surface has poor wear resistance and sho...

Problems solved by technology

However, due to the cold bonding method of ceramic lagging, the requirements for the treatment of the surface of the drum and the environment are relatively high; since the ceramic lagging is pasted in a single-piece structure, there will be certain gaps between the pieces. It cannot be bonded with the roller, once water or mud invades and the tape is squeezed, it will inevitably form a glue layer; in addition, due to the bonding of small ceramic sheets and rubber sheets after long-term use, it is easy to fall off; the high hardness of ceramics reduces The friction coefficient between the belt and the belt will cause driving slippage in extreme rainy and snowy weather, which will aggravate the wear of the belt and seriously affect the service life of the belt

[0006] Therefore, at present, the domestic belt conveyor pulley rubber-covering wear-resistant technology has its own advantages and disadvantages. The wear-resistant technology of traditional technology cannot fully meet the requirements of on-site working conditions. It needs to be replaced by a new product that integrates the advantages of various traditional technologies and avoids traditional technologies. The shortcomings of rubber, the advantages of good impact resistance and adhesion of rubber and the high wear resistance of ceramics and polyurethane are organically integrated, and become this new material invention.
