technical field

The invention relates to a method for producing an antistatic floor and an antistatic wallboard with macromolecular chemical materials. the

Background technique

Traditional anti-static flooring can be divided into different base materials and veneer materials: steel base, aluminum base, composite base, particle board base (also called wood base), calcium sulfate base, etc. The veneer can be melamine (HPL) and PVC. the

The price of aluminum base and calcium sulfate base is relatively high, and the floor of aluminum base will not rust, but the precision of domestic aluminum base floor is not high, and the price of imported aluminum base is too high; 

The steel base and composite base are moderate, but the section of the steel base floor is prone to rust, so the section needs to be painted for anti-rust treatment, and the section of the composite base floor should also be treated for dust prevention. the

The price of the particle board base is relatively low, but the water absorption rate is too high, and the fire resistance is poor, and the load capacity is low, so it is not suitable for places with high requirements. the

Using melamine (HPL) as a veneer is easy to age and peel, the surface is easy to scratch, and the corners are easy to fall off. the

Using PVC as a veneer is easy to age, and it is not easy to clean after laying, the floor is easy to age, and the fire performance is not good. the

The present invention will include A component (polyol, chain extender, foam stabilizer, blowing agent, catalyst, flame retardant, filler material and conductive material) and B component include (isocyanate, epoxy resin) by mass The ratio of 1:1-2 is mixed and injected into the mold, and then the anti-static floor made by processing can not only overcome the shortcomings of the above-mentioned various anti-static floors, but also has the functions of heat preservation, moisture resistance, flame retardancy, anti-aging, no deformation, and direct laying without keel The advantages. The most prominent feature is that the whole body has the same anti-static and flame-retardant properties, and even the glue used in the installation process also has anti-static and flame-retardant properties (separate patent application). In addition, it has the characteristics of flexible specifications and styles, simple and convenient construction, etc. the
