Abstract

The antistatic floor board consists of facing layer, base layer and bottom layer and it features the composition of base layer of magnesite powder 60-66 wt%, magnesium chloride 15-20 wt%, talcum powder 5-15 wt%, wood dust 12-15 wt% and modifier 0.9-1.5 wt%. Its main advantages include low cost, high strength, anticorrosion, and antistatic, fireproof and waterproof property. The said antistatic floor board is suitable for use in TV station, electronic control room, and computer room.

Description

Antistatic raised floor

The invention belongs to a kind of antistatic raised floor.

In the eighties, the antistatic raised floor that uses in the electron trade is to make with aluminium alloys, cost an arm and a leg, and intensity does not reach standard, and some adopts shaving board to make the plate base, and it is not prevented fires, and is non-watertight, and also antistatic not is out of favour.After the nineties, produce all steel floor, but cost height, weight big, sell also bad.Produce cement-bonded wood chipboard recently, because its fire prevention is poor, explosive to uniform temperature, particularly weight is big, is difficult to bear.

The objective of the invention is at the shortcoming that exists in the prior art, the spy develops that a kind of cost is low, intensity is high, anticorrosion, antistatic, waterproof, fireproof antistatic raised floor.

The technical scheme of antistatic raised floor of the present invention is: it mainly is made of surface layer, plate base and bottom, it is characterized in that the composition material of described plate base and percentage by weight (%) thereof are respectively:

Magnesium oxychloride 60-66 magnesium chloride 15-20 French chalk 5-15

Wood powder 12-15 modifier 0.9-1.5

The wood powder of described 12-15% can replace with the perlite of 8-12%.Contain gauze wire cloth in the described plate base, glass fiber screen cloth or bamboo reinforcement.Described surface layer is a PVC sheet material.Described bottom is sheet iron or aluminium foil.Be coated with anti-static coatings on described iron sheet surface.Around described aluminium foil, stud with aluminium extruded sections or adhesive tape.Described iron sheet envelopes described plate base, and except that upper surface, the anti-static coatings spraying is all adopted on five surfaces of other of iron sheet.The composition material of described antistatic powder coating and percentage by weight thereof (%) are: alkyd resin, epoxy resin or polychlorostyrene fat resin 40-50, conducting medium 20-30, filler 20-30%, curing compound 2-3, levelling agent 3-4.

The technical performance of the plate base of anlistatig movable floor of the present invention:

Reach GB6650-86 after testing, GB2828-87 computer floor standard, its mechanical strength deflection when all carrying 26000N is below the 1.55mm, when point load 2500N, deflection is below the 1.5mm, and fire prevention detects oxygen index (OI) greater than 80% through GB8924-98 and the compulsory standard GB50222-95 of the Ministry of Construction; Waterproof is overflow with water purification and was steeped 1 year, and nothing is crooked after taking out, and weight does not increase; Antistatic resistance system: 1.0 * 10 ⁶-1.0 * 10 ⁸Ω (ohm).

The major advantage of antistatic raised floor of the present invention is: cost is low, intensity is high, anticorrosion, antistatic, fire prevention, waterproof, be a kind of desirable antistatic floor material, this floor is applicable in the machine rooms such as TV station, electronic program machine room, military project, command centre, public security, bank.The structure of antistatic raised floor of the present invention as shown in Figure 1, in Fig. 1: 1 surface layer, 2 plate bases, 3 bottoms, 10 movable floors.

Embodiment 1:

Movable floor 10 as shown in Figure 1, it is by surface layer 1, and plate base 2 and bottom 3 constitute, and surface layer 1 wherein is a PVC sheet material, bottom 3 is an aluminium foil, and the composition material and the percentage by weight thereof of plate base 2 are respectively: magnesium oxychloride 62%, magnesium chloride 18%, French chalk 10%, sawdust 9%, modifier 1%.

In plate base 2, be placed with the glass fiber screen cloth, be provided with adhesive tape at aluminium foil 3 peripheries.

Embodiment 2:

Movable floor 10 as shown in Figure 1, its surface layer 1 is a PVC sheet material, bottom 3 is an iron sheet, be coated with anti-static coatings on the iron sheet surface, the composition material of plate base 2 and percentage by weight thereof are: magnesium oxychloride 66%, magnesium chloride 14%, French chalk 11%, perlite 7.5%, modifier 1.5%, and in plate base 2, be placed with bamboo reinforcement.

Embodiment 3:

Movable floor 10 as shown in Figure 1, its surface layer 1 is a PVC sheet material, and the composition material of bottom plate base and percentage by weight thereof are with embodiment 1, and the iron sheet of its bottom 3 coats whole plate bases, and except that upper surface, all the other five surfaces all are coated with antistatic coating.
