Abstract

The invention discloses an environment-friendly rubber pipe which comprises a modified polypropylene resin pipe body and a TPE elastomer rear plug. The invention further discloses a preparation method of the environment-friendly rubber tube. Rice straw fibers and polypropylene are subjected to cross-linking polymerization, the composite material is endowed with easily degradable and renewable environment-friendly performance, a modified silane coupling agent is used for modifying the rice straw fibers, so that the number of -OH on the surfaces of the fibers is reduced, the hydrophobicity and lipophilicity of the fibers are increased, the compatibility of the fibers and a polymer matrix is improved, and aluminum sol is thermally decomposed into nano Al2O3; nanometer Al2O3 shows a certain degree of lipophilicity and cooperates with polysiloxane, the affinity of the plant fibers and polypropylene is also improved, in addition, in the preparation process of the TPE elastomer rear plug, the feeding ratio of the SEBS elastomer to the polypropylene is strictly controlled to be 0.03: 1, and a rear plug prepared under the ratio has high light transmittance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an environment-friendly rubber hose and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic polymer polymerized from propylene as a monomer, referred to as PP. Polypropylene has rich sources of raw materials and cheap prices. Compared with other plastics, it has low relative density, excellent processing performance, high yield strength, tensile strength and elastic modulus, and better chemical resistance. Its products are non-toxic, tasteless, and have good gloss. They have become widely used materials in the packaging fields of automobiles, electrical appliances, daily necessities and furniture. At present, the industry is not limited to focusing on the mechanical and physical properties of the material itself such as impact resistance and compression resistance, and is gradually becoming more and more interested in materials wi...
