Problems solved by technology

[0004] The floor is currently also suitable for the floor decoration of some factories, especially for companies that need to transport materials frequently in daily situations, especially electronic factories, etc., which put forward higher requirements for the anti-static and impact resistance of the floor. The more commonly used floors have relatively low antistatic and impact resistance, which cannot meet the needs of these companies in the future

Embodiment approach

[0028] As a preferred embodiment, the epoxy resin is bisphenol A epoxy resin;

[0029] Preferably, the bisphenol A epoxy resin is polyimide modified bisphenol A epoxy resin.

[0030] The preparation method of the bisphenol A type epoxy resin modified by polyimide comprises the steps:

[0031] (1) Preparation of polyimide: 2.13g of 4,6-diaminoresorcinol hydrochloride (DAR, CAS No. 16523-31-2) and 1mL of triethylamine were dissolved in 25mL of N-methyl Add 3.1g of diphenyl ether tetracarboxylic dianhydride (CAS No. 50662-95-8), 10mL of toluene and 1.0g of glacial acetic acid to the base pyrrolidone, then raise the temperature to 180°C and keep it for 5 hours. Precipitate in methanol, filter and dry in vacuo to obtain polyimide.

[0032] (2) the polyimide, norbornene diacid anhydride, 2,4,6-tri( Dimethylaminomethyl) phenol was mixed, stirred while heating, heated to 120° C. for 1 hour, and then heated to 150° C. for 3 hours to obtain a polyimide-modified bisphenol A epoxy resi...

Embodiment 1

[0104] An impact-resistant, anti-static and environment-friendly coating material, which is composed of two components, A and B. In parts by weight, the A component includes the following raw materials: 55 parts of epoxy resin, 12 parts of color paste, 33.5 parts of colored sand parts, 5 parts of monoepoxy glycidyl ether, 8.5 parts of fillers, 1.8 parts of defoamers, and 0.7 parts of leveling agents; the B component includes 55 parts of aminophenyl compounds.

[0105] Described epoxy resin is the bisphenol A type epoxy resin of polyimide modification, and the preparation method of the bisphenol A type epoxy resin of described polyimide modification comprises the steps:

[0106] (1) Preparation of polyimide: Dissolve 2.13g of 2,4-dihydroxy m-phenylenediamine hydrochloride and 1mL of triethylamine in 25mL of N-methylpyrrolidone, add 3.1g of diphenyl ether tetra Carboxylic acid dianhydride (CAS No. 50662-95-8), 10mL of toluene and 1.0g of glacial acetic acid, then heated to 180°C...

Embodiment 2

[0136] An anti-shock, anti-static and environment-friendly coating material, which is composed of two components, A and B. In parts by weight, the A component includes the following raw materials: 45 parts of epoxy resin, 9 parts of color paste, 14 parts of colored sand 3 parts, 3 parts of monoepoxy glycidyl ether, 6 parts of filler, 1 part of defoamer, 0.1 part of leveling agent; the B component includes 45 parts of aminophenyl compounds.

[0137] The epoxy resin is a polyimide-modified bisphenol-A epoxy resin, and the preparation method of the polyimide-modified bisphenol-A epoxy resin is the same as in Example 1.

[0138] The color paste was purchased from Dongguan Beinu Composite Materials Co., Ltd.

[0139] The colored sand is a mixture of epoxy resin sand containing modified graphene oxide and resin colored sand, 4 parts of epoxy resin sand containing modified graphene oxide, and 10 parts of resin colored sand.

[0140]The resin colored sand was purchased from Shanghai ...

Abstract

The invention belongs to the technical field of terrace materials, and particularly relates to a graphene composite impact-resistant anti-static environment-friendly coating material and a preparationmethod thereof. The graphene composite impact-resistant anti-static environment-friendly coating material is composed of a component A and a component B. The component A is prepared from the following raw materials in parts by weight: 45-70 parts of epoxy resin, 14-40 parts of colored sand and 3-8 parts of monoepoxy glycidyl ether. The component B comprises 45 to 70 parts of an amino phenyl-containing compound.

Description

technical field [0001] The invention belongs to the technical field of floor materials, and in particular relates to a graphene composite anti-shock, anti-static and environment-friendly coating material and a preparation method thereof. Background technique [0002] With the advancement of science and technology, my country's flooring industry has developed by leaps and bounds, and has been widely used in many specific fields, such as plastic runways in sports fields, repairing of cracks in building concrete, filling and repairing gaps between beams and buildings, indoor Floor decoration and so on. [0003] So far, the development of related technologies of floor materials has been very mature, and can be roughly divided into three categories, namely epoxy resins, acrylics and polyurethanes, the three major resin systems. In these systems, the matrix resin is generally an amorphous viscous liquid, which has no obvious melting point, tends to soften when heated, and then gra...
