[0009] 5. Accumulated charge, dust
Although the polyurea prepared by the above method has good water resistance, flexibility, high elongation at break, plant puncture resistance, aging resistance, etc., it does not consider that polyurea products will accumulate electric charges during long-term use. Static electricity, static electricity can cause damage to sensitive equipment, etc.

Abstract

The invention discloses a polyurea wear-resistant coating material with an anti-static function and a preparation method thereof. The polyurea wear-resistant coating material comprises a component A and a component B, wherein the component A is prepared from isocyanate, polyether polyol and diluent; and the component B is prepared from a chain extender, polyether amino resin, diluent, an active filler, auxiliary and a conductive filler. The conductive filler in the polyurea wear-resistant coating material has the characteristics of light color, stable performance, less addition amount, and the like. The polyurea wear-resistant coating material has the characteristics of high curing speed, water proofness, wear resistance, high tensile strength and the like.

Description

technical field [0001] The invention relates to a polyurea wear-resistant coating material with antistatic function and a preparation method thereof. It belongs to the field of high-elastic anti-corrosion and waterproof polymer chemical materials for construction engineering. It can be used in high-speed railways, building roofs and basements, oil tanks, subways, automobiles, road bridges, pools, coastal facilities, hydropower, thermal power, nuclear power and other fields. Building anti-corrosion and waterproof. Background technique [0002] Polyurea (SPUA for short) is an emerging waterproof and wear-resistant material with only a dozen years of development history. Component A is prepared by reacting isocyanate with oligomer diol or triol; component B is composed of amino-terminated polyether, liquid amine chain extender, pigment, filler and auxiliary agent. Components A and B are sprayed or cast polyurea elastomer through the host and spray gun. This process belongs t...
