Embodiment Construction

[0068] The present invention is further illustrated below with examples, but the present invention is not limited thereto.

[0069] The preparation method of embodiment comprises the following steps:

[0070] (1) take the raw material by the weight of the components in the above-mentioned each embodiment and each component;

[0071] (2) High-temperature rubber mixing: the components weighed in parts by weight include nitrile rubber, aluminum hydroxide, polyethylene glycol, antimony trioxide, protective wax, oxidized paraffin wax, anti-aging agent (4020), DCP cross-linking agent, anti-aging agent (RD), antioxidant (AST-500), dioctyl ester (DOP), and epoxy soybean oil (ADDA) are put into the mixing room and mixed until high temperature discharge. The plastic is made of EVA material, and the density The refining temperature is about 160°C;

[0072] (3) Milling: Pour the output from step (2) into the mill to slice, the thickness of the cut film is 6.5mm, and the width of the...

Abstract

The invention relates to an environment-friendly rubber plastic heat-insulating material and its preparation method, and the rubber plastic heat-insulating material is prepared from butyronitrile rubber (NBR), antimonous oxide (Sb2O3), zinc oxide, sulfur, dioctyl-phthalate (DOP), epoxidized soybean oil (ADDA), mercaptobenzothiazole (M), anti-aging agent (4020), antioxidant (AST-500), protective wax (HGB-3), ethylene-vinyl acetate copolymer (EVA), dicumyl peroxide (DCP crosslinking agent), polyethylene glycol (PEG), stearic acid, aluminum hydroxide, foaming agent-dinitrosopentamethylene tetraamine (H), diphenylguanidine (D), pigment, anti-aging agent (RD), anti scorching agent (PVI), and the like. By limited use of raw materials containing chlorine ion components and cooperation of a new vulcanization foaming technology, environment-friendly and heat-insulating performances of the product can be stabilized, the prepared environment-friendly rubber plastic heat-insulating material has no corrosion performance in use, the material life is prolonged, metal pipes in refrigeration equipment can be effectively protected, and maximized performance of the product can be performed.

Description

technical field [0001] The invention relates to the field of environment-friendly rubber and plastic heat insulation materials, in particular to an environment-friendly rubber and plastic heat insulation material for heat preservation of air-conditioning or HVAC metal pipelines without chloride ions or containing a very small amount of chloride ions and a preparation method thereof. Background technique [0002] Nowadays, NBR / PVC rubber and plastic foaming materials are used for air-conditioning insulation pipes, and the formula contains more chlorine elements, and the chlorine ions produced are highly corrosive to copper pipes. For example, in November 2012, Gree air-conditioning inspection standards required The chloride ion content in the air-conditioning rubber and plastic insulation pipe is less than 100mg / kg; the polyvinyl chloride paste resin in the existing NBR / PVC rubber and plastic foaming material formula, its raw material such as S700 polymerization residue vinyl ...
