Abstract

The invention discloses a making method and device of carbon nanometer pipe with high-density conductive hard-polyurethane foam plastic, which comprises the following steps: oxidizing the surface of carbon nanometer pipe; adopting distilled water as diluent; vibrating and grinding through ultrasound; dispersing carbon nanometer pipe in the polyether polyol; evaporating water in the system; obtaining the composite liquid of carbon nanometer pipe and polyether polyol; blending with organic tin, silicon oil and water according to certain proportion through mechanic stirring device evenly; mixing with certain quantity of isocyanate completely; casting in the mould; closing mould lid; ripening; obtaining the product.

Description

1. Technical field [0001] The invention belongs to the technical field of new polymer materials, and relates to a method for producing conductive or antistatic rigid polyurethane foam plastics by utilizing carbon nanotubes (CNTs) and polyurethane. 2. Background technology [0002] Polymer materials have excellent comprehensive properties (such as light weight, corrosion resistance, easy processing, low cost, convenient use, etc.), and are widely used in the field of defense industry. The volume resistivity of polymer materials is usually very large, about 10 10 ~10 20 Between Ω·cm, it is undoubtedly very good as an electrical insulating material. However, with the development of the national defense electronics industry and information technology and the requirements for electromagnetic shielding of weapons, wave-absorbing stealth and special items (such as high-energy explosives, precision electronic and electrical components), polymer materials with certain conductive fu...
