Abstract
A permanently antistatic fire-retarding colour veneer used for floor, wall, ceiling and consol is prepared from a surface paper layer with two surfaces coated by conducting composite mica powder and multiple layers of paper immersed in phenolic resin containing carbon black through pressing and solidifying. Its advantages include stable antistatic performance, high antiwear and fire-retarding nature, not cracking and low cost.
Description
The present invention relates to a kind of thick china, refer to a kind of permanently antistatic fire-retarding colour veneer especially.
Mainly contain two kinds of antistatic thick chinas at present on the domestic market: permanently antistatic PVC plate and impermanency antistatic wood based panel.The main raw material of permanently antistatic PVC plate is polyvinyl chloride resin and conductive particle (carbon black or graphite), rely on the three-dimensional link of the conductive particle formation of certain relative quantity to play anti-static electrification, its advantage is that antistatic performance is stable, but easy irregular cracking, and wear no resistance, color is single.But not being its antistatic performance, the defective of permanently antistatic wood based panel maximum fluctuates with the variation of ambient humidity, and passing in time and quicken to weaken, the sheet resistance index is low.
The purpose of this invention is to provide stable, wear-resisting, fire-retardant, easy to crack, the not cheap coloured facing plate of a kind of antistatic performance.
The object of the present invention is achieved like this: will build up certain thickness through certain chemically treated colored top layer paper and multilayer bottom paper, in 170～240 kilograms per centimeter
2Heat preservation solidification was shaped to thick china in 20～40 minutes under pressure, 130～140 ℃ the condition.The thickness of this thick china is 0.6～2.0mm, and surface resistivity is 1 * 10
6～1 * 10
8Ω .cm, specific insulation are 1 * 10
7～1 * 10
9Ω .cm.The number of bottom paper is adjusted with the thickness of sheet material; Hardening time is relevant with the thickness of plate, and plate is thick more, corresponding increase hardening time; Pressure during curing, temperature are relevant with the characteristic of the resin of processing top layer paper.
The chemical treatment method of colored top layer paper is the melamine resin coating 0.080～0.120mm that applies the composite conducting mica powder that is mixed with 10%～20% percentage by weight on paper two surfaces with rubbing method, 110 ℃～130 ℃ prebakes in 10 minutes.The fineness of composite conducting mica powder, mix the size of the surface resistivity of percentage decision sheet material.
The chemical treatment mode of bottom paper is after paper passes through the resin impregnating of the carbon black that mixes 4 ‰～8 ‰ percentage by weights, prebake in 10 minutes about 120 ℃～140 ℃.The fineness of carbon black, the specific insulation size of mixing percentage decision sheet material.
When aforesaid colored top layer paper and bottom paper are carried out chemical treatment, before uncoated and before not flooding, can directly add percentage by weight and be the solid, powdery alkalescence Firebrake ZB of 0.8-1.2% in the corresponding resin liquid on bottom and top layer, other condition and step are with preceding identical.Can strengthen the flame retardant effect of thick china of the present invention like this.
The composite conducting mica powder melamine resin coating of top layer paper is light blue, also can be mixed into other color with other colorants, and is not only attractive in appearance, and can be used as different signs
Permanently antistatic fire-retarding colour veneer of the present invention can be applied to the surface lining of sheet materials such as antistatic floor, antistatic wallboard, antistatic furred ceiling, antistatic operating desk.
The present invention has significant excellent specific property:
1) owing to the bottom of sheet material and the conductive particle that all there is stable chemical performance on the top layer, no
Only play the effect of antistatic, and rely on conductive particle to be in contact with one another the formation electrical network
The network layer, the nonvolatil antistatic of energy;
2) if before uncoated and before not flooding, straight in the liquid resin on bottom and top layer
Connect and add solid, powdery alkalescence Firebrake ZB, behind the sheet metal forming, fire-retardant index can reach oxygen and refer to
Several 37 (GB/T7911-1999) and FV-1 (GB4609-84), flame retardant effect is bright
Show;
3) thick china is formed body with the paper, and each is little to difference, not easy to crack;
4) contain special film forming matter-melamine in the top layer, solidify back hardness height, ginseng
According to GB7911-1999 standard (thermosetting resin impregnated paper high pressure laminated decorative board)
Measure: wear-resistant revolution is 400 commentaries on classics, and wearing valve is changeed smaller or equal to 0.08 gram/100,
Thereby improved the service time of thick china;
5) the composite conducting mica powder coating on top layer is light blue, can be with other colorant blendings
Become relevant colors, not only attractive in appearance, and can be used as different signs;
6) bottom is conductive particle with the carbon black, and cost is low, and the top layer is with the composite conducting mica powder
Be conductive particle ... coat is 0.08.～0.120mm only, and integrated cost is cheap.
The composite conducting mica powder that 1. pairs of colored top layers of embodiment paper adopts when carrying out chemical treatment be
Tin oxide and antimony oxide that 600 purpose mica powders surface coats 0.2～2 μ m thickness mix
Thing, its proportioning are mica: tin oxide: antimony oxide=51: 36: 13, (can adopt
The prosperous C type 600 order composite conducting mica powders of basis that Hai Junjiang Science and Technology Ltd. produces);
The proportioning of melamine resin is a melamine: formaldehyde=2: 7, (can select four for use
Chuan Chuanization group company produces 100% purity melamine＜GB/T79567-1999〉and
37% purity formaldehyde＜GB9009-88 that Shanghai solvent factory produces 〉).
When the fineness of mixing 16% in the coated on both sides of colored top layer paper is that 600 purposes are compound
Behind the melamine resin 0.100mm of conductive mica powder, at 120 ℃ of following preliminary dryings
The surface resistivity of the sheet material that makes when doing 10 minutes is 1 * 10
7～1 * 10
8Ω .cm.To the bottom paper carry out chemical treatment the time phenolic resins that adopts proportioning be-benzene
Phenol: formaldehyde=5: 7, (the optional 100% purity benzene of producing with the Shanghai Gaoqiao chemical plant
Phenol＜GB339-89〉and 37% purity formaldehyde＜GB9009-of producing of Shanghai solvent factory
88>)。
When to the bottom paper process, the paper process is mixed the carbon black of 5 ‰ 1000 order fineness
Resin impregnating after, the volume resistance of the sheet material that after 130 ℃ of prebake, makes
Rate is 1 * 10
7～1 * 10
8Ω .cm.3. build up certain through certain chemically treated colored top layer paper and multilayer bottom paper
Behind the thickness, the heat preservation solidification aftershaping is the present invention under condition under certain pressure and the temperature
Thick china.The number of bottom paper is adjusted with the thickness of sheet material, and 0.6mm is thick
Plate is with 5 on the paper of 100 grams, and the plate of 1.0mm is with 8 on 100 paper that restrain; During curing
Between relevant with the thickness of plate, plate is thick more, corresponding increase hardening time, pressure, temperature
Relevant with the characteristic of resin:
1) thickness is that the plate of 0.8mm (soaks with 100 6 on gram half bleaching sulfate wood pulp paper
