Abstract

The invention provides a silane crosslinked PE / EVA (polyethylene / ethylene-vinyl acetate copolymer) flexible water hose and a preparation method thereof and solves the technical problems of narrow application range, poor transparency and absence of bacteriostatic ability of an existing water pipe. The silane crosslinked PE / EVA flexible water hose is prepared from 85% by mass of a material A and 15%by mass of a material B; the material A is prepared from components in parts by weight as follows: 68.79-70 parts of PE, 28.68-30 parts of EVA, 0.1-0.12 parts of DCP and 1-1.2 parts of silane; the material B is prepared from components in parts as follows: 97.6-97.8% of PE, 2 parts of a silver-carrying calcium phosphate antibacterial agent and 0.2-0.4 parts of a catalyst. The invention further provides the preparation method of the silane crosslinked PE / EVA flexible water hose.

Description

technical field [0001] The invention relates to a water delivery hose and a preparation method thereof, in particular to a silane crosslinked PE / EVA water delivery hose and a preparation method thereof. Background technique [0002] At present, the water pipe industry has a great demand for transparent hoses. Water pipes made of different materials have great differences in temperature resistance. For example, polypropylene (PP) pipes cannot be used in low temperature environments, and heat-resistant polyethylene (PERT) pipes The high temperature resistant temperature can only reach about 60 ℃, and the scope of application is narrow, which cannot meet the needs of low temperature resistance and higher high temperature at the same time. Moreover, most of the existing water pipes have poor transparency, mostly white and black pipes, and there are precipitations. Once corrosion or damage occurs inside the pipes, people cannot observe the situation in the pipes in a timely and c...
