Embodiment 1

[0026] A. React natural crystalline sulfur with a modifier to generate a sulfur polymer with a network polymer structure. The specific method is to heat the sulfur to 120°C and mix it with the modifier. The weight of the modifier is 2%. , and continue to heat the sulfur-generating polymer. The modified sulfur polymer has strong stability, strong waterproof, anti-seepage and corrosion resistance, and good quick-drying property.

[0027] Modifiers can be aromatic hydrocarbons, such as styrene, vinyltoluene, methylstyrene, etc.; they can also be diene (genus) hydrocarbons or olefinic hydrocarbons, such as: 2,3 - indane, dicyclopentadiene. The modifier may be one or a combination of two or more of the above compounds.

[0028] B, after the polymer melting of the sulfur that step A obtains is sprayed to form waterproof, anti-corrosion layer through cleaning and drying in advance on the surface layer, the thickness of waterproof, anti-corrosion layer should be 0.3mm-1MM to play wa...

Embodiment 2

[0030] A. The difference from step A in Example 1 is that the sulfur is refined from petroleum or desulfurized from natural gas, and the weight of the modifier is 10%. The modification process needs to mix the natural sulfur with the modifier after being heated to 150° C. Continued heating yields polymers of sulfur.

[0031] B, then mix solid powder in the polymer that obtains sulfur, preferably fly ash, its particle is uniform, with low cost, main purpose is to increase the strength and density of the material of the present invention, improve water resistance and impermeability. Solid powder can also choose one or a mixture of several of the following materials: fly ash after coal combustion, steel slag, ash after garbage incineration, construction waste ash, solid waste powder from chemical plants , Radioactive solid waste particles. The mixing amount of the solid powder should be 3%-10% (weight ratio) of the sulfur polymer, and the inorganic solid powder should be 50 mesh...

Embodiment 3

[0034] With step A difference in the embodiment 2, the weight of modifier is 25%, and the heating melting temperature of sulfur is 160 DEG C; Mix with the polymer weight 10%-20% (weight ratio) of sulfur with solid powder weight, solid The powder is preferably steel slag, and its particle size is 80 mesh. It is sprayed on the surface layer after hot stirring and mixing, and its purpose is to improve the wear resistance of the surface layer.

Abstract

To solve the problem that the prior art has no paint with waterproof, watertight and anticorrosive performances, the invention provides waterproof paint with good waterproof, watertight and anticorrosive performances. The waterproof paint comprises a sulfur polymer which has a netted macromolecule structure and also comprises solid powder particles interfused into the polymer. The waterproof paint can be applicable for a waterproof, watertight and anticorrosive pool of concrete, tunnels, underground, bridge surfaces and chemical plants, a methane pool and other surfaces which need waterproofing and anticorrosion.

Description

technical field [0001] The invention belongs to a waterproof coating, in particular to a waterproof coating for the construction field. Background technique [0002] The coatings used in construction are mainly divided into waterproof coatings and anti-corrosion coatings, which have the functions of waterproof, anti-seepage and anti-corrosion respectively. In practical applications, the coating layer is often required to have waterproof and anti-corrosion functions at the same time. For example, the impact of acid rain is increasing, and external coatings are required to be waterproof and acid-resistant at the same time. Utilize existing technology to only be coated with waterproof coating and anticorrosion coating respectively to form waterproof layer and anticorrosion layer. The problem is that the outermost coating, whether it is a waterproof layer or an anti-corrosion layer, will be damaged under the action of acid rain, and the built-in anti-corrosion or waterproof lay...
