Problems solved by technology

The polyurea waterproof coating mainly made of aromatic sprayed polyurea elastomer uses aromatic isocyanate as the main raw material to synthesize isocyanate prepolymer or semi-prepolymer, and diethyltoluenediamine is used as the chain extender. It is easy to age and cannot meet the requirements of a waterproof surface layer that is exposed to the environment for a long time and requires high color retention
There are not many waterproof materials based on non-polar materials reported in the prior art, but non-polar materials can avoid the aging problem of organic waterproof materials

Embodiment Construction

[0015] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0016] In the embodiments of the present invention, the weight of each portion is selected to be 1 kg, and each component is made of commonly used materials in the field of construction engineering. The formulas of the specific embodiments are shown in the table below.

[0017]

[0018] The above-mentioned examples were prepared using the following method steps: (1) add common ash, fine sand, rubber powder, wood fiber, and cellulose ether into the container in sequence, and stir at the same time, so that the entire system is finally mixed evenly; (2) Add water to the homogeneously mixed system prepared in step (1), and stir at the same time to make the homogeneously mixed system. The fine sand used is preferably 50-100 mesh.

[0019] The above-mentioned examples were tested for waterproof performance, and the results showed that the waterproof...

Abstract

The invention discloses a waterproof mortar material which comprises, by mass, 200 to 400 parts of ordinary lime mortar, 300 to 900 parts of fine sand, 10 to 50 parts of glue powder, 1 to 5 parts of wooden fibers, 1 to 5 parts of cellulose ether and 300 to 860 parts of water. The waterproof mortar material is prepared by uniformly mixing the above-mentioned components with stirring and is uniformly coated when utilized; the material can effectively resist water, facilitates construction and prevents boundary defects.

Description

technical field [0001] The invention relates to a waterproof material, more specifically, to a waterproof mortar material and a preparation method thereof. Background technique [0002] With the development of my country's economic construction, there is an urgent need for an advanced waterproof material in the difficult waterproofing of large-scale infrastructure construction such as high-speed railways, subways, tunnels, and water conservancy projects. This kind of waterproof coating should overcome the shortcomings of traditional waterproof materials such as aging resistance, no exposure, low strength, no puncture resistance, high requirements on the construction environment, slow curing, and low work efficiency. [0003] The polyurea waterproof material in the prior art is a material with a 100% solid content, which utilizes the -NCO of the A component and the -NH of the B component 2 It is solidified into a film by the reaction between them, and is applied by two-compo...
