Abstract

The invention provides an anti-static coating used for a computer, and a preparation method thereof. The anti-static coating is prepared from the following ingredients: organosilicone polyurethane, alkyd resin, xylene, composite conducting filler, polyhydric alcohol, trimethylolpropane, modified foamy copper, bamboo charcoal material, deformer, flatting agent, antioxidant and water. The anti-static coating prepared with the preparation method has the advantages of short surface dry time, good heatproof effect, small surface resistance, high abrasive resistance, low cost, simple preparation method and wide application range.

Description

technical field [0001] The invention belongs to the technical field of antistatic coatings, and in particular relates to an antistatic coating for computers and a preparation method thereof. Background technique [0002] At present, the conductive materials used in anti-static coatings in my country can be divided into two categories according to their composition and conductive mechanism: structural type (also known as intrinsic type) and composite type (also known as additive type). The conductive material of the intrinsic conductive coating is the polymer itself. The conductive material of the additive conductive coating is a conductive substance (metal, graphite, etc.) added to the insulating polymer, and the conductive material is used to make the polymer conductive. [0003] Application number 201310723392.X, titled a high-temperature oxidation-resistant coating for electronic products and its preparation method, the coating contains the following components in parts ...
