Problems solved by technology

[0004] Generally, the surface resistance of the antistatic plate is 10 7 ~10 9 Ohm is only a very thin layer, which needs to be adhered to other composite materials. It is troublesome to use, high in cost, and it is difficult to meet the requirements of fire and water resistance; for important facilities such as airplanes and spacecraft, simple surface antistatic can no longer meet the normal requirements. Operational Security Requirements
On the premise of not changing the excellent performance of the existing decorative boards such as high density, it is difficult to make them reach the antistatic level (that is, the surface three-dimensional resistance of 10 3 ~10 6 ohm), although some surface resistance can meet the standard, but the volume resistance is not good, which has become a difficulty in breaking through the existing technology

Abstract

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.

Description

technical field [0001] The invention relates to an antistatic decorative board and a preparation method, in particular to an antistatic combite board and a preparation method. Background technique [0002] As a kind of decorative board, Kangbeit board is a one-piece decorative material produced by dissolution and irreversible aging hardening under high temperature and high pressure. This kind of board material has high stability, shockproof and fall resistance, cold and heat resistance, fire resistance, moisture resistance and smoke resistance, and its density is mostly 1.4 to 1.5g / cm 3 between. The application range of the decorative board is extremely wide, ranging from the aerospace industry to civilian daily necessities, kitchen countertops, washstands, dining tables, desks, door leaves in home life, and even bathroom and toilet compartments in public places, sinks, reception counters, Lockers, ceilings, desks and office cubicles can all be made of decorative panels. ...
