Abstract

The invention discloses a masterbatch of rubber and plastic foaming thermal insulation materials, which relates to the field of rubber and plastic foaming thermal insulation materials, and comprises the following components in parts by mass: 5 to 18 parts of nitrile rubber (NBR); ) 10-18 parts; chlorinated paraffin 0-15 parts; aging-resistant modifier 3-15 parts; aging-resistant plasticizer 3-20 parts; flame retardant 25-40 parts; foaming agent 10-15 parts; 10-25 parts of filler; 0.1-2% parts of anti-aging agent. Using butyl rubber, EPDM rubber or a mixture of two kinds of anti-aging modifiers, using dipropylheptyl phthalate as anti-aging plasticizer, the anti-aging performance is obviously improved, and can be maintained for a long time Its elasticity prevents cracking and increases its service life. The invention also discloses a preparation method of the rubber-plastic foaming thermal insulation material.

Description

technical field [0001] The invention relates to the field of rubber and plastic foaming thermal insulation materials, in particular to a masterbatch of rubber and plastic foaming thermal insulation materials and a method for preparing the rubber and plastic foaming thermal insulation materials. Background technique [0002] At present, NBR / PVC system rubber and plastic foam insulation materials have been widely used in air conditioners, refrigerators and other household appliances and outdoor pipe insulation and other fields. Existing rubber and plastic foam materials are prone to aging at high temperature, lose elasticity and even crack, resulting in shortened service life. [0003] At the same time, with the introduction of the REACH regulations of the European Union for the preventive management of all chemicals entering its market, the export of household appliances such as air conditioners and refrigerators needs to specially control the content of short-chain chlorinat...
