Embodiment 1

[0065] In the present embodiment, liquid material component is:

[0066]

[0067] The powder components are:

[0068]

[0069] The liquid-to-powder ratio of the formula is 1:3.3, according to the enterprise standard >, "JC / T 1066-2008 Limits of Harmful Substances in Architectural Waterproof Coatings" and "JC / T 984-2011 Polymer Cement Waterproof Mortar" to test and evaluate the formula.

[0070] Table 3 shows the odor test results of the waterproof material prepared by the formula of Example 1 (ie the example formula 1 in the table) and common waterproof materials on the market.

[0071] Table 3 Odor test results

[0072]

[0073] The results of the odor test show that the odor of the waterproof material formulated in Example 1 can reach level 2 in the first odor test, while the odor of ordinary waterproof material products on the market can only reach level 2 after the fourth cycle.

[0074] The harmful substance detection result of example formula 1 is shown in t...

Embodiment 2

[0083] In the present embodiment, liquid material component is:

[0084]

[0085] Powder formula:

[0086]

[0087] The liquid-to-powder ratio of the formula in this example is 1:2.5, according to the enterprise standard >, "JC / T 1066-2008 Limits of Harmful Substances in Architectural Waterproof Coatings" and "GB / T 23445-2009 Polymer Cement Waterproof Coating" tests and evaluates this formula.

[0088] Table 6 shows the odor test results of the waterproof material prepared by the formula of Example 2 (ie the example formula 2 in the table) compared with common waterproof materials on the market.

[0089] Table 6 Odor test results

[0090]

[0091] The results of the odor test show that the example formula 2 can reach the odor intensity level 2 after 3 cycles, while the common waterproof materials on the market cannot meet the requirement of clean odor.

[0092] The harmful substance detection result of example formula 2 is shown in table 7.

Abstract

The invention discloses an environmentally-friendly odor removing dual-component cement-based waterproof material, which is prepared from the following ingredients in parts by weight: 1 part of liquidmaterial ingredient and 1-6 parts of powder material ingredient, wherein the powder material ingredient comprises cement, sand, inert filler, active filler and chemical additive; the liquid materialingredient comprises polymer emulsion, defoamer, bactericide and water. The environmentally-friendly odor removing dual-component cement-based waterproof material has the characteristics of extremelylow ammonia content, odor removal, good environment protection performance, good physical performance, good construction hand feeling and convenience in use and is suitable for various construction technologies including spraying, rolling and brushing, and VOC (volatile organic compounds), formaldehyde and harmful heavy metal powder can not be detected.

Description

technical field [0001] The invention relates to a two-component cement-based waterproof material, in particular to an environment-friendly and odor-free two-component cement-based waterproof material. Background technique [0002] Two-component cement-based waterproof materials have been emerging in my country since the 1990s. Especially in recent years, the development of two-component cement-based waterproof materials has been very rapid. However, the performance of the current two-component cement-based waterproof materials is uneven, especially However, there are disadvantages such as containing harmful heavy metals and releasing toxic and pungent odors. Specifically, there may be VOC, formaldehyde, APEO, harmful heavy metals, and acrylamide in the polymer emulsion, where acrylamide reacts with strong alkaline cement to release ammonia with a pungent odor; formaldehyde that may exist in fungicides; Formaldehyde and harmful heavy metals that may exist in the water agent. ...
