Abstract

The present invention relates to one facture of the antistatic floor which is lignum-base metallic-membrane plating. The technique is to afford one kind of material which will not only keep the physical mechanical property of the lignum-base material, but also suit to the antistatic request. The following is the facture of this invention. The preparative of the primary material, it contains the lignum which is used for base and the metal which is used for exterior metallic-membrane. Drying process, assure the moisture content is less than 10% or theoretical dry. Process the flat blank, and deal with polishing. Shelling-out and drying, use the colophony dope to brush the ligneous floor and then drying. Evaporate, deliver the flat blank into the vacuum coating apparatus and evaporate. The degree of vacuum of the surface should be controlled between 5x10-2Pa and 10x10-5Pa, the time should be controlled between 0.5 hour and 3 hours, the thickness of the film should be controlled between 0.2micron m and 20micron m. The present invention can also be used in trimming.

Description

It with timber the preparation method of antistatic floor of the metal-coated surface of matrix

Technical field

The present invention relates to a kind of is the preparation method of antistatic floor of the metal-coated surface of matrix with timber.Be applicable to the decoration field of decorating.

Background technology

Wood floors have specific strength height, heat insulation performance good, advantages such as better elastic are arranged, be widely used for the various places of interior decoration.Dry timber is not suitable for the production or the workplace of antistatic because its electrical insulation capability height in use easily produces accumulation of static electricity, as the inflammable and explosive workshop of ultrapurification environment, computer or communication apparatus machine room, high dust etc.Static might cause dust suction seriously to be difficult to purify and destroy the ultrapurification environment, thereby influences the operation of product appearance or precision instrument; Static discharge can make various precision instruments, electronic devices and components are breakdown and scrap, or causes the Device Host fault; In industries such as explosive, colliery, oil, chemical industry, weaving, static discharge causes the on fire or blast of inflammable and explosive substances, causes huge serious accident.So antistatic floor is used widely in above-mentioned place.

Present antistatic floor is divided three classes substantially: the one, and all steel or the full aluminium type floor of all adopting metal material; The 2nd, on the compound floor of antistatic materials such as enterprising row metal paper tinsel of the matrix of particieboard and fiberboard or conductive plastics surface veneer; The 3rd, adopt and add PVC or the rubber floor covering that antistatic additive is prepared from.First kind cost is higher, and the consumption of metal material is big; Second kind of surface and high base strength are not high; And the third is being short of aspect intensity or the wearability usually to some extent.

Summary of the invention

The technical problem to be solved in the present invention is: providing a kind of is the preparation method of antistatic floor of the metal-coated surface of matrix with timber, be intended to make the both whole physical and mechanical property that has kept original wood materials of material, satisfied anlistatig requirement simultaneously, the metal-plated rete has very high adhesive force, and the consumption of metal seldom, meets the intensification principle that non-renewable resources are utilized.

The technical solution adopted in the present invention is:

1) raw material are prepared

1. the wood materials as matrix comprises solid wood, particieboard, fiberboard, glued board, core-board;

2. the metal material as surface coating comprises aluminium, copper, nickel, chromium, titanium and alloy thereof;

2) drying

The moisture content that makes timber is less than 10% or carry out over dry and handle;

3) processing slab

Process the slab of wood floors, and carry out sanding and handle;

4) brushing and oven dry

Adopt resinae coating that the wood floors slab is brushed or sprayed, and dry;

5) evaporation

Slab sent into carry out evaporation in the vacuum coater, its vacuum degree control is 5 * 10 ^-2～10 ^-5Between the Pa, the evaporation time was controlled at 0.5～3 hour, and the thickness of surface coating metal can be adjusted by coating process between 0.2～20 μ m as required.

The invention has the beneficial effects as follows: the first, use the mode of vacuum coating that metalized is carried out on the wood floors surface, metal consumption is few, and its antistatic property is suitable with the all-metal material floor; The second, use this evaporation mode in the antistatic property that increases material surface, not destroy intrinsic other performance (as mechanical mechanics property, heat insulation performance etc.) of wood materials again; The 3rd, the antistatic property of this coating is permanent stable, and the variation with humidity, time does not change; The 4th, the surface resistivity of this coating can be carried out suitable adjusting by coating process as required.

The specific embodiment

The present invention be a kind of be that the surface of matrix is the permanence antistatic floor of plated film metal with the wood materials, the thickness of its surface coating metal is 0.2～20 μ m, can adjust by coating process as required.The antistatic property of its coating is stable, the peel strength height, and the metal material consumption is little, does not destroy the original mechanical mechanics property of wood floors simultaneously.

The base material that the present invention relates to is selected wood materials for use, can be solid wood, particieboard, fiberboard, glued board, core-board.

The plated film metal aluminium that relates to, copper, nickel, chromium, titanium etc., and alloy.

The resinae coating that relates to can be melamine coating, polyurethane coating, phthalic resin coating, also can be its modified product.

The surface resistivity of coating is relevant with factors such as base material kind, substrate surface roughness, thickness of coating.Along with coating thickens, its surface resistivity reduces thereupon, and the surface resistivity of coating is 10 ⁰～10 ⁵Between the Ω.

Preparation method of the present invention is according to the following steps: carry out drying earlier, the moisture content that makes timber is less than 10% or carry out over dry and handle, and processes the slab of wood floors, and carries out sanding and handle, adopt resinae coating that the wood floors slab is brushed or sprayed again, and dry.Send into then and carry out evaporation in the vacuum coater, its vacuum degree control is 5 * 10 ^-2～10 ^-5Between the Pa, the evaporation time was controlled at 0.5～3 hour.The thickness of surface coating metal can reach 0.2～20 μ m, can adjust by coating process as required.

Embodiment 1: solid wooden floor board surface aluminizer

Aluminium film color and luster silvery white, and be difficult for oxidation, the surface coating that is suitable for wood floors is handled.The plating material is selected 99.99% fine aluminium silk, and the working vacuum degree is 1 * 10 ^-2Pa, the evaporation time is 1 hour, coating film thickness is 1.5 μ m.Both reached antistatic effect after the plating, its surface also has good glossiness, has reached decorative effect again.

Embodiment 2: face veneer red copper plating film

The red copper film has good decoration effect, and the copper wire of selection 99% is as the plating material, and working vacuum is 2 * 10 ^-2Pa, the evaporation time is 0.6 hour, coating film thickness is 0.5 μ m.The plating rear surface has good antistatic effect, has reached decorative effect again.
