Abstract

An antistatic one-time plastic-coated wooden board used in an antistatic working environment. A conducting layer (2) is added in a common one-time plastic-coated wooden plate. When static electricity exists on the decorative surface layer (1), the static electricity can be leaked to the ground through the conductive layer (2) to prevent the damage.

Description

Anti-electrostatic one-time plastic-covered wood board

The utility model relates to the sheet material of the timber processing of using in a kind of antistatic working environment, specifically a kind of have an electrostatic-proof function, and surface recombination has plastics, the sheet material of timber processing.

Common particieboard with the timber making, fiberboard etc. can once-combinedly be gone up the thermosetting resin decorative surface layer in process of production.It is determined by international standard ISO4586 " plastics-thermosetting resin is the decorative laminate on basis ", standard GB 7911 " thermosetting resin decorative laminate " and GB4897 " particieboard technical conditions " etc., this product is because the gummed of top layer and basic unit is once to finish simultaneously with the curing of resin, so gel fastness height, cost is also low.But this product has such problem: be compounded in the plastics of surface of wooden substrate such as particieboard, because resistance is very big, generally greater than 10 ¹¹Europe, not only can not leak static by it, it also is easy to produce static with other article frictions, therefore present floor of in the antistatic working environment, using, timber-works such as terminal identity have to be moulded again by secondary again on wood based panel and stick one deck antistatic thick china again, so not only increased technique for sticking one time, and after in use very easy the coming unglued of veneer that be stained with, thick china is its flatness of assurance and intensity as an independent product simultaneously, its thickness must be more than 0.8mm, be that the thickness once moulded again is more than three times, thickness increases antistatic performance and degenerates, and cost but greatly increases.

The purpose of this utility model is that a kind of improved wood based panel of once moulding again will be provided, and it has the good electrostatic hazard performance that prevents.

The purpose of this utility model is achieved in that conductive layer of increase between once-combined plastics surface layer to wood based panel and wooden basic unit, makes electrostatic energy pass through the conductive layer admittance, reaches the surface resistivity of moulding wood based panel again or system resistance 10 ⁵Europe to 10 ¹⁰Between the Europe.

The utility model is owing to only increasing conductive layer former once moulding again on the wood based panel basis, so simple in structure; Simultaneously,, improved product quality and performances price ratio so cost is low owing to be once to mould again and have antistatic performance.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Accompanying drawing is a schematic diagram of moulding wood based panel according to the antistatic that the utility model proposes again.

Below in conjunction with description of drawings according to detail and the working condition that the utility model proposes.

This is moulded wood based panel again and comprises: architectural surface ［ 1 ］, it generally is to soak the MF(melamine formaldehyde resin) or MPF(melamine-fluosite) paper make; Conductive layer ［ 2 ］ generally is to have the MF resin or the glue of acetylene carbon black to make; Wooden basic unit ［ 3 ］ generally is to be made of particieboard, medium-density plate, glued board or fiberboard, also has the bottom ［ 4 ］ with antistatic performance, and its material is identical with ［ 1 ］ or ［ 2 ］.

Moving articles such as the human body static that contact architectural surface ［ 1 ］ produces when work, because ［ 1 ］ is very thin, can leak into soon on the conductive layer ［ 2 ］ by it, and conductive layer ［ 2 ］ is connected with earth system in use, therefore static can be gone into ground safety quickly, has prevented that static is to the harm of sensitive components with to the interference of electronic equipment.

Claims

The antistatic that uses in a kind of antistatic working environment is once moulded wood based panel again, this plate has architectural surface [1], wooden basic unit [3] and bottom [4], it is characterized in that: also have a conductive layer [2] between architectural surface [1] and the wooden basic unit [3], make the surface resistivity or the system resistance of moulding wood based panel again reach 10 ⁵Europe to 10 ¹⁰Between the Europe.
