Abstract
The ingredients (wt%) of the invented plates are: polyvinyl-chloride resin 100, caleium curbonate 10-200, dioctyl phthalate 10-40, aluminium sulphite 0.5-3, stearic acid 0.5-3, conductive carbon black 0.1-5 and quaternary ammonium salt 0.1-5. Said invention can suit the needs of leakage resistance up to 10 K ohm-100 mega chm under 30-500 V condition. The exterior of the product can be designed into various patterns similar to terrazzo figure.
Description
The present invention relates to functional construction material, particularly relevant functional plastic sheet material and preparation method thereof.
All multidisciplinary in electronics, post and telecommunications, communication, chemical industry, weaving etc., because science and technology development, requirement to inside, house antistatic is more and more higher, mating formation of antistatic plastic sheet material become requisite architecture engineering material, but the product of each manufacturer production at present, normally in resin, sneak into 10～30 conductive carbon blacks and mix that refining is moulded, the antistatic of pulling-on piece, a kind of black of hot-forming one-tenth is moulded plate, apply mechanically GB6650-86 computer floor antistatic standard, test its bleeder resistance over the ground with 500V megohm meter, its allowed band is:
A level: 1 * 10
5-1 * 10
8
B level: 1 * 10
5-1 * 10
9
But under many occasions, the standard of narrow like this range is difficult to be suitable for, as producing the microelectronics factory of MOS, cmos device, when device meets the 30V electrostatic potential, device will puncture or half puncture, and necessarily require plastic plate to have antistatic performance this moment under 30V voltage.In addition, under other occasions, can propose 100V again, 200V, 300V etc. require different antistatic performance.And the product that prior art is produced only can guarantee to have antistatic performance under certain voltage conditions, when voltage changes, or meet and just be difficult to guarantee its antistatic performance when sudden voltage applies, or its R-V characteristic can not guarantee to reach even variation and does not have sudden change.
The present invention is directed to and existing mould plate, be difficult to take into account the antistatic performance shortcoming under the various voltages, provided and to adapt to 30～500V voltage, have the plastic plate and the processing technology of even non-linear resistance characteristic because range is narrow.
The present invention adds processing such as antistatic additive, plasticizer, stabilizing agent, lubricant, inserts, carbon black for realizing its purpose to Corvic (PVC) material, to guarantee its uniformity and even non-linear effect.In the present invention, material each component (wt%): Corvic 100, filler is selected charcoal acid calcium 10～200 for use, plasticizer is selected dioctyl phthalate 10～40 for use, stabilizing agent is selected tribasic aluminium sulfite 0.5～3 for use, lubricant is selected stearic acid 0.5～3 for use, and conductive black is 0.1～5, and antistatic additive is selected quaternary amine 0.1～5 for use.Above Corvic and various auxiliary agent are mixed, refining was moulded 1～5 hour, pulling-on piece is broken into particle, mix with conductive black and antistatic additive again, pressurization 10～800 handkerchiefs heated up 0.2～2 hour at 130 ℃～280 ℃, were incubated 0.2～2 hour, with hot-forming sheet material, carry out surface finish and the fixed thick bulk that is processed into again.
Superiority of the present invention is:
1. test voltage is under the situation of 30～500V after testing for the product that utilizes the present invention to produce, and the bleeder resistance value is 1 * 10
5-1 * 10
8In the scope.
2. the product appearance of Sheng Chaning has changed the single color (black) of existing product, can be designed to each pattern of similar water mill decorative pattern.
3. the goods anti-wear performance is improved, and the abrasion loss on GB4085 standard code anti-static plastic floor is 0.02g/cm
2, the mill amount of disappearing of product of the present invention is 0.001g/cm
2
Embodiment of the present invention are as follows:
With polyvinyl chloride resin 100kg, calcium carbonate 100kg, dioctyl phthalate 30kg, tribasic aluminium sulfite 3kg, stearic acid 1kg puts into mixed agency and mixes after 1 hour, material is emitted to drop into to refine in the extruder mould, through mill pulling-on piece (extruder temperature is 160 ℃, 170 ℃, 180 ℃, 160 ℃ of the temperature of mill).The plastic sheet of pulling out is through putting into the broken mechanism of glass after the cooling naturally, and glass is broken into moulds a particle.Take by weighing the 100kg particle, 0.2kg conductive carbon black, 0.2kg quaternary amine mixed 10 minutes in special use, made surface attachment one deck conductive carbon black of particle, it is molded that the particle that will adhere to carbon black is sent hot press to, 165 ℃ of press temperature, the demoulding gets the black sheet material of moulding, and the black sheet material of moulding is decided thick shearing through the sand mill sand milling, finally makes the surface and has the black conductive path, integral body has three-dimensional conductive network, and outer appearnce is like the sheet material of terrazzo.
