The invention discloses an antistatic compact grade laminate. A core plate of the antistatic compact grade laminate is made by the following raw materials in percentage by weight: 40-50% of fiber, 35-45% of phenolic resin, 3-8% of antistatic agent, 5-10% of carbon black and 1-3% of coupling agent; and the antistatic agent is coated on the surfaces of decorative papers. During the preparation of the compact grade laminate, the antistatic agent is added in the core plate and the decorative papers on two surfaces of the core plate respectively, so that a stereoscopic antistatic effect jointly acted by interior and surfaces is formed and excellent properties such as antistatic property and high density are obtained; the antistatic compact grade laminate is widely suitable for special industries or occasions having antistatic requirements on building decorative materials; the surface and stereoscopic antistatic property is lasting and not easy to fade way; and the carbon black has electric conductivity. Moreover, according to the invention, the characteristic of being made by paper of the conventional compact grade laminates is changed and craft paper is replaced by fiber, so that the aim of reducing the cost is achieved.

The coloring agglomerate consists of pigment, plastic assistants and carrier resin, and the plastic assistants include N, N'-ethylene amido bistearate, polyvinyl wax, zinc stearate and antistatic agent. The preparation process includes mixing the materials, high speed kneading in kneading pot with current controlled in 30-50 A, extruding the mixture in a double-screw extruder at 100-160 deg.c, cooling, stoving and pelletizing. The polyethylene tire-packing film with the coloring agglomerate has no color penetration, no adhesion, no falling off and antistatic performance, and may be used to complete the packing and storing of rubber tire at about 80 deg.c.
