Embodiment 1

[0013] An environment-friendly high-performance inorganic coating additive formulated from the following raw materials in weight percent:

[0014]

[0015] Mix the above-mentioned raw materials in proportion and stir evenly to obtain.

Embodiment 2

[0017] An environment-friendly high-performance inorganic coating additive formulated from the following raw materials in weight percent:

[0018]

[0019] Mix the above-mentioned raw materials in proportion and stir evenly to obtain.

Embodiment 3

[0021] An environment-friendly high-performance inorganic coating additive formulated from the following raw materials in weight percent:

[0022]

[0023] Mix the above-mentioned raw materials in proportion and stir evenly to obtain.

[0024] The product of the present invention is a gasified powder, white powder, with a specific surface area of ​​30-35m 2 / g, the general dosage is 3% to 6% of the cementitious material, the water reducing rate is 20% to 30%, the early strength is increased by 80% to 100%, and the strength is increased by more than 30% after 28 days of use. The cohesive force of the body is increased by more than 50%, and the impermeability index is increased by more than 80%, which can obviously reduce the shrinkage and creep of inorganic coatings. In the production of inorganic dry powder coatings, when the ratio of water to cement is mixed with 3%, the fluidity of the slurry is greatly increased, and it has good plasticity. It can increase the polymer ...

Abstract

The invention discloses an environment-friendly high-performance inorganic coating additive. The additive is prepared from the following raw materials by weight: 76% to 80% of inorganic nanoscale micropowder, 10 to 15% of natural polymeric modified starch, 8% to 12% of a highly-efficient SM water-reducing agent and 0.5% to 1% of an anticaking agent. The additive provided by the invention is non-toxic and odorless, is free of chlorine salt, does not discharge volatile organic compounds (VOC) in the use process, has the characteristics of high water reduction, low water bleeding, self waterproofing to inorganic coatings, etc., and can significantly change mixability and fluidity of the inorganic coatings.

Description

technical field [0001] The invention relates to the field of additives, in particular to an environment-friendly high-performance inorganic coating additive applied to building materials. Background technique [0002] With the rapid development of my country's economy and the gradual promotion of urbanization, the central and local governments have paid more and more attention to the protection of the ecological environment. In recent years, various policies have been continuously introduced to limit the emission of VOC volatiles in the construction field, and vigorously promote green and environmentally friendly building materials. . At present, the coatings and paints in the construction field on the market contain a large amount of VOC volatiles, which cause great harm to the human body. There are few products that do not contain VOC volatiles and various additives. The additive of the invention is non-toxic, tasteless, does not contain chlorine salt, does not emit VOC vo...
