Description
Technical field
The present invention relates to environment friendly plastic thermal insulation material field, be specifically related to a kind of without chlorion or containing environment-friendly type rubber-plastic heat insulation material for the insulation of air-conditioning or HVAC metallic conduit of denier chlorion and preparation method thereof.
Background technology
Air-conditioning heat insulation pipe adopts NBR/PVC rubber plastic foam material now, and formula in chlorine element more, and the chlorion producing has larger corrodibility to copper pipe, as in November, 2012, the inspecting standard of Gree requires the chloride ion content in air-conditioning rubber-plastic thermal insulation pipe to be less than 100mg/kg; Pvc resin paste grade in existing NBR/PVC rubber plastic foam material formula, its raw material is if the residue vinylchlorid of S700 polymerization is in 10mg/kg, and raw material, if the residue of P450 polymerization is in 7.81mg/kg, comprises that vinyl chloride-vinyl acetate resin, CPE etc. can have chloride ion content in addition.
2012.11.19 the newly-increased chloride ion content testing method of Gree:
A) sample thief weight is 1g left and right, sample is put into the encloses container of 100ml;
B) in container, add 40ml pure water, cover sealing cover, manually vibrate approximately 30 seconds, make sample be stained with moisture; And under the condition of 90 DEG C, place 24 hours;
C) while taking out encloses container, manually vibrate again approximately 30 seconds, after solution is cooling, take out liquid, adopt ion chromatograph to analyze soak solution ions content;
D) ion content of soak solution is converted to the ion content of insulating pipe.
The harm of chlorion pitting is under the surfaces such as stainless steel, copper pipe, galvanized sheet, to produce large depression again.Low flow velocity or stagnant water " conventionally can cause and pitting, very high flow velocity can stop corruption " erosion property material is concentrated along surface, and slows down the trend of pitting.Once depression is initiated and reaches the stable stage, it will expand continuously in stainless steel; Because the acidity of solution in cave is more much better than than surrounding environment, metal wherein is just more easily corroded.At initiating stage, corrosion product can form a duricrust and cover above depression, and the size of this sealed area is the lasting key of pitting.Positive charge density in depression is very large, can attract chlorion to keep the electric neutrality in cave by electromigration.Due to the hydrolysis of metal chloride and the generation of HCl, even water body near neutral, the pH in stainless steel depression also can approach 1.Because be primary anode (depression) with respect to large negative electrode (peripheral region), erosion rate just may be very high.In general, 304/316 stainless pitting tendencies will increase with the rising of temperature and chlorine ion concentration.
