Abstract

The invention provides a rubber composite material, which comprises the following components in parts by weight: 100 parts of natural rubber, 6 parts of zinc oxide, 1 part of stearic acid, 1.5 parts an antioxidant, 0.1 part of a scorch retarder, 0.7 part of an accelerator CZ, 0.3 part of an accelerator TMTD, 2.5 parts of sulfur, 40 parts of carbon black, 10 parts of a wood cellulose-montmorillonite rubber reinforcing agent, and less than or equal to 6 parts of liquid rubber. According to the composite material provided by the invention, the liquid rubber is added to a formula of rubber, so that the tensile strength and the elongation at break of rubber can be improved, the dispersion of the lignocellulose-montmorillonite reinforcing agent in a natural rubber matrix is improved, the interfacial interaction of the rubber and the wood cellulose-montmorillonite reinforcing agent is effectively enhanced, and the environment is protected. The invention also provides a preparation method of the rubber composite material. The preparation method has the advantages of simple process, low cost and easiness in industrial production.

Description

technical field [0001] The invention belongs to the technical field of rubber polymer composite material preparation, and in particular relates to a rubber composite material and a preparation method thereof. Background technique [0002] With the increasing scarcity of petrochemical resources and serious environmental problems, the use of renewable biomass raw materials instead of petrochemical raw materials to synthesize new polymer materials has attracted more and more attention. Lignocellulose is the most abundant renewable resource in nature. Lignocellulose is rich in hydroxyl groups. After vulcanization, it is easy to chemically react with inorganic fillers and rubber to form a resin network. It is used as a filler in rubber and is an excellent reinforcing material. However, its interface adhesion with non-polar or weakly polar polymer matrix is ​​poor, and the hydrophilic fibers cannot be well dispersed in the polymer matrix, resulting in a decrease in the mechanical ...
