Problems solved by technology

The Chinese invention patent "corrosion-resistant and flame-retardant structural composite board and its preparation method" with the publication number CN1654202 provides a board and its preparation method. Combustion agent, and then cured by the curing system to make a polymer material cladding layer, reproduce the molding technology of pouring concrete to strengthen the base layer and then make a structural composite board. The board has excellent corrosion resistance and flame retardant properties, but due to its The main component of the cladding layer is thermosetting resin, so it is difficult to have scratch resistance. In use, it is easy to be scratched by metal or sharp objects, which affects the service life and appearance to a certain extent.

Embodiment 1

[0016] In this embodiment, glass hollow microspheres are selected as the anti-scratch agent. First, the glass hollow microspheres are pretreated with a coupling agent, and then mixed with diluent petroleum ether and coupling agent titanate to form a paste. 1% by weight of hollow microspheres, under room temperature, stir in a high-speed kneader for 5 minutes to make it evenly mixed.

[0017] See attached figure 1 , to prepare a scratch-resistant 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 phenolic resin and epoxy resin with a weight ratio of 1:1 mixed resin, 400 mesh talcum powder, carbon black, flame retardant ammonium polyphosphate, reinforced fiberglass, flame retardant hexabromocyclododecane, coupling agent pretreated glass hollow microspheres at a ratio of 100:120:1 : 30: 1: 10: 3 weight mixing and stirring evenly, then add curing agent d...

Embodiment 2

[0022] In this embodiment, glass hollow micropowder is selected as the anti-scratch agent. First, the glass hollow micropowder is pretreated with a coupling agent, and then mixed with diluent petroleum ether and coupling agent silane to a paste. Silane accounts for 1.5% of the weight of the glass hollow micropowder. , at room temperature, stirred in a high-speed kneader for 10 minutes to make it evenly mixed.

[0023] See attached figure 1 , to prepare a scratch-resistant 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 Resin mixed resin, then with 500 mesh kaolin, iron yellow, flame retardant ammonium polyphosphate, toughened fiber polypropylene fiber, brominated epoxy resin, coupling agent pretreated glass hollow micropowder according to 100:100:1: 40:1:20:4 weight ratio after mixing, s...

Embodiment 3

[0028] In this embodiment, a copolymer of dimethylsiloxane and ethylene oxide is selected as the anti-scratch agent.

[0029] See attached figure 1 , to prepare a scratch-resistant 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, chrome yellow, flame retardant magnesium hydroxide, polybutadiene diol, flame retardant chlorinated paraffin 70, dimethyl siloxane and polyethylene oxide copolymer by 100 : 120: 1: 30: 5: 15: 5 after mixing in weight ratio, stir evenly, then add curing agent dimethylaniline and benzoyl peroxide, the weight ratio is 1: 1, and the amount accounts for 10% of resin weight , stirred evenly, poured into the mold, cured naturally at 20°C for 20-40 minutes, and then cured at 100°C for 40 minutes to prepare a polymer materia...

Abstract

An antiscratch composite plate is composed of a basic layer made of hydraulic cementing material, a transition layer made of polymer and concrete, and a surface layer made of antiscratch agent, diluent, and surfactant or coupling agent or block copolymer or super disperser. Said antiscratch agent is prepared from organic silicon-polyether copolymer and / or hollow glass microbeads (or microparticles).

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 scratch resistance and a preparation method thereof. Background technique [0002] Corrosion-resistant plates have been widely used in various fields. The Chinese invention patent "corrosion-resistant and flame-retardant structural composite board and its preparation method" with the publication number CN1654202 provides a board and its preparation method. Combustion agent, and then cured by the curing system to make a polymer material cladding layer, reproduce the molding technology of pouring concrete to strengthen the base layer and then make a structural composite board. The board has excellent corrosion resistance and flame retardant properties, but due to its The main component of the cl...
