Description
Technical field
The present invention relates to a kind of water tube hose and working method thereof touched; The silane crosslinking polyolefin elastic body that is particularly related to the environmentally-friendly sanitary of a kind of Shao A hardness in 55 ~ 95 scopes touches water tube hose; It can be through the test of mikrobe toxicity; Have more outstanding sanitation performance, be especially suitable for use as the pipe in the water that touches of braided tube, flower sprinkling tube etc.
Background technology
Braided tube that
are traditional or flower sprinkling tube can use terpolymer EP rubber (EPDM) sebific duct or SE (PVC) sebific duct to do usually and touch pipe in the water.These touch, and there is number of drawbacks in pipe in the water; Little etc. if any peculiar smell, loss of properties on aging, use temperature scope, the most important thing is not environmental protection of EPDM or PVC material itself, pvc material self is chloride; And EPDM also can add multiple harmful additive etc. in the course of processing; Ooze out polluted-water easily, the braided tube or the flower sprinkling tube that therefore use these materials to process generally all do not reach sanitary index, are difficult to test through mikrobe toxicity.
silane crosslinking polyolefin elastic body material has attracted more and more people's research and use owing to have good low-temperature resistance, performance such as wear-resisting, ageing-resistant and corrosion-resistant and excellent bending property.There is patent report that the silane crosslinking polyolefin elastic material is used as cable insulation, obtained the flexible insulation cable.Many pieces of patent reports are also arranged about the preparing method's of silicane cross-linking polyolefin composition research and about the research of other physicochemical properties of silane cross-linked polyolefin material and improvement etc., but the report of the toxicity aspect of still unmatchful silane cross-linked polyolefin material and the report of the research in the pipe in the water that touches that is applied to high braided tube of hygienic requirements or flower sprinkling tube at present
Summary of the invention
technical problem to be solved by this invention be overcome braided tube in the prior art or flower sprinkling tube touch that pipe does not reach the defective of hygienic requirements in the water, a kind of water tube hose that touches of environmentally-friendly sanitary is provided.
another object of the present invention provides the above-mentioned working method of touching water tube hose.
the 3rd purpose of the present invention is that the above-mentioned water tube hose that touches is used for touching in the water of braided tube or flower sprinkling tube and manages, and makes the braided tube or the flower sprinkling tube product that have outstanding sanitation performance, can not polluted water.
