[0003] In the prior art, the Chinese invention patent "An Antistatic Floor Veneer and Its Manufacturing Method" with the publication number CN1114606 discloses a manufacturing method of an antistatic floor veneer, which adds metal particles, inorganic Aqueous compounds and adhesive polymers are formulated with PVC resin, plasticizer dioctyl ester, stabilizer trisalt, lubricant stearic acid, filler talcum powder, polyolefin and antistatic agent, and then rolled. Due to the lack of compatibility between the antistatic agent and the resin matrix, the antistatic performance is affected to a certain extent.
[0004] The Chinese invention patent "corrosion-resistant and flame-resistant structural composite board and its preparation method" with the publication number CN1654202 uses the molding technology of pouring thermosetting resin to decorate the cladding layer first, then pouring concrete to reinforce the base layer and then making the structural composite board. , the plate has excellent corrosion resistance, flame retardant and other properties, but it does not have antistatic properties, so its application range is limited to a certain extent

Embodiment 1

[0018] In this embodiment, fatty acid polyoxyethylene ether is selected as the antistatic agent.

[0019] See attached figure 1 , to prepare a kind of antistatic composite board with hydraulic cementitious material as the base layer, polymer concrete as the transition layer, and polymer material as the cladding layer. The method is to mix the resin with the weight ratio of phenolic resin and epoxy resin 1:1, 400 mesh talcum powder, carbon black, ammonium polyphosphate, glass fiber, hexabromocyclododecane, fatty acid polyoxyethylene ether are mixed according to the weight ratio of 100:120:1:30:1:10:3 and Stir evenly, then add diethylenetriamine, the amount of which accounts for 15% of the weight of the resin, stir evenly, pour into the mold, and naturally cure at room temperature for 20-40min, then cure at 90°C for 100min to prepare a polymer Material cladding [3] with a thickness of 3mm.

[0020] Mix the above mixed resin, diethylenetriamine and No. 425 Portland cement in a ...

Embodiment 2

[0024] The antistatic agent of this embodiment selects conductive carbon black, first conducts super-dispersion treatment on conductive carbon black, mixes 100 parts of conductive carbon black, 5 parts of hyperdispersant and petroleum ether into a paste, and pulverizes it in a cone mill at room temperature for 40 minutes , mix until uniform.

[0025] See attached figure 1 , to prepare an antistatic composite board with hydraulic cementitious material as the base layer, polymer concrete as the transition layer, and polymer material as the cladding layer. The method is to mix unsaturated resin and epoxy resin with a weight ratio of 1:1, 500 mesh kaolin, iron yellow, ammonium polyphosphate, polypropylene fiber, brominated epoxy resin, and conductive carbon black are mixed in a weight ratio of 100:100:1:40:1:20:3 and stirred evenly , then add the curing system as triethylamine, methyl ethyl ketone and cobalt naphthenate, the weight ratio is 1:1:1, and the amount accounts for 15% ...

Embodiment 3

[0030] In this embodiment, graphite is selected as the antistatic agent. Firstly, the graphite is subjected to hyperdispersion treatment, and 100 parts of graphite, 4 parts of hyperdispersant and petroleum ether are mixed into a paste, and pulverized in a cone mill at room temperature for 50 minutes, and mixed until uniform.

[0031] See attached figure 1 , to prepare a kind of antistatic composite board with hydraulic cementitious material as the base layer, polymer concrete as the transition layer, and polymer material as the cladding layer. The method is to use a mixed resin of phenolic resin and unsaturated resin, and its weight ratio 1:1, 400 mesh calcium carbonate, carbon black, magnesium hydroxide, polybutadiene diol, chlorinated paraffin-70, and graphite are mixed in a weight ratio of 100:120:1:30:5:15:3 Stir evenly, then add dimethylaniline and benzoyl peroxide, the weight ratio is 1:1, and the amount accounts for 10% of the resin weight ratio, stir evenly, pour into ...

Abstract

An antistatic composite plate used in electronic and computer areas is composed of a basic layer made of water-hardening cementing material, a transition layer made of polymer and concrete, and a surface layer made of high-molecular material and the antistatic agent prepared from amphophilic compound, electric conductive carbon black or graphite or metal powder, diluent or coupling agent, block copolymer and super-disperser. It has high antistatic, fire-proof, mechanical and anticorrosion performance.

Description

technical field [0001] The invention relates to a structural composite board and a preparation method thereof, in particular to a structural composite board in which a polymer material layer and an inorganic material layer are compounded with corrosion resistance, flame retardancy and antistatic properties and a preparation method thereof. Background technique [0002] With the development of social economy, plates with antistatic properties have been widely used, especially in some special fields and places such as electronics and computers. [0003] In the prior art, the Chinese invention patent "an antistatic floor veneer and its manufacturing method" with the publication number CN1114606 discloses a manufacturing method of an antistatic floor veneer, which adds metal particles, inorganic Water-containing compound and adhesive polymer are prepared by PVC resin, plasticizer dioctyl ester, stabilizer trisalt, lubricant stearic acid, filler talcum p...
